For a growing UK business, reaching the VAT registration threshold is an important accounting milestone. It can affect pricing, invoicing, bookkeeping, cash flow, contracts, reporting processes and the way a business communicates with customers.
A business does not become VAT registered simply because its annual profit reaches a particular level. VAT registration is primarily connected with taxable turnover and the relevant rolling 12-month period. A business can therefore have relatively modest profits but still have to register for VAT if its taxable turnover exceeds the applicable threshold.
As of 2026, the UK VAT registration threshold is £90,000 of taxable turnover. The deregistration threshold is £88,000. The registration threshold has applied since 1 April 2024, following an increase from £85,000.
For a business approaching £90,000, waiting until the end of its financial year to check turnover can create a compliance problem. VAT registration is based on specific tests, including the value of taxable turnover in a rolling 12-month period and, in some circumstances, expectations about the next 30 days.
This guide explains what a growing UK business should check before reaching the VAT threshold, how taxable turnover is calculated, what sales count towards the threshold, when registration is required, what happens after registration, how pricing may change, and how to prepare the bookkeeping system.
What Is the UK VAT Registration Threshold?
The VAT registration threshold is the level of taxable turnover at which a business is generally required to register for VAT.
The current UK VAT registration threshold is £90,000. The deregistration threshold is £88,000.
The key term is taxable turnover.
This does not mean:
- Total money in the bank
- Net profit
- Gross profit
- Total business income in every situation
Taxable turnover generally relates to the value of supplies that are relevant for VAT purposes.
This distinction is important because a business may have income that does not count towards the VAT registration threshold in the same way as standard-rated taxable sales.
A business approaching the threshold should therefore review its transactions rather than simply looking at the bank balance or annual accounts profit.
The VAT Threshold Is Based on a Rolling 12-Month Period
One of the most important points for growing businesses is that the VAT registration test is not simply based on a calendar year or accounting year.
The taxable turnover test generally looks at the value of taxable supplies over the previous 12 months.
This means a business should monitor turnover continuously.
For example, suppose a business has the following taxable turnover:
- January to March: £18,000
- April to June: £20,000
- July to September: £22,000
- October to December: £24,000
The total for the 12-month period is £84,000.
The business is approaching the threshold and should monitor the next transactions carefully.
If the following month adds £8,000, the business may exceed £90,000, but the calculation also needs to remove the oldest month from the rolling 12-month period.
This is why a fixed annual turnover figure can be misleading.
A monthly VAT threshold tracker should show the current rolling 12-month taxable turnover and highlight how close the business is to £90,000.
What Counts as Taxable Turnover?
Taxable turnover generally includes the value of taxable supplies made by the business.
These can include:
- Standard-rated sales
- Zero-rated sales
- Some reduced-rated supplies
- Certain other taxable supplies
Zero-rated supplies are important because they can still count towards the VAT registration threshold even though the VAT charged to the customer is 0%.
This means a business selling zero-rated goods cannot automatically assume that VAT registration is irrelevant.
The VAT treatment of each type of sale should be identified before calculating taxable turnover.
Businesses with mixed supplies need particular care because exempt income is treated differently from taxable turnover.
Taxable Supplies Versus Exempt Supplies
Not all income is treated the same way for VAT purposes.
A business may make:
- Standard-rated supplies
- Reduced-rated supplies
- Zero-rated supplies
- Exempt supplies
- Outside-the-scope transactions
These categories should not be mixed together when monitoring the VAT threshold.
For example, a business with £100,000 of income does not automatically have £100,000 of taxable turnover.
The actual VAT treatment of the underlying supplies needs to be established.
This can be particularly relevant to businesses that provide more than one type of service.
A business should review its product and service list and assign an appropriate VAT treatment to each category.
What Should a Business Do When Turnover Reaches £80,000?
There is no legal requirement to register simply because turnover reaches £80,000.
However, reaching this level should trigger closer monitoring because the business is approaching the £90,000 registration threshold.
At this stage, the business should:
- Confirm its rolling 12-month taxable turnover.
- Review the VAT treatment of its sales.
- Check whether any zero-rated sales are included.
- Identify exempt or outside-scope income.
- Review expected sales for the next few months.
- Check whether the business could cross the threshold quickly.
- Review pricing and contracts.
- Check accounting software.
- Improve VAT record keeping.
- Discuss registration timing with an accountant if the threshold is likely to be exceeded.
The earlier these checks are made, the easier the transition becomes.
What Should a Business Do at £85,000?
At £85,000, the business is only £5,000 below the current VAT registration threshold.
At this point, monitoring should be more frequent.
A business with rapidly increasing sales could cross £90,000 within a short period.
Review:
- Current rolling 12-month turnover
- Current month’s sales
- Confirmed customer orders
- Contracts already signed
- Recurring subscriptions
- Seasonal sales
- Expected large invoices
- Sales pipeline
The business should also check whether the next 30 days could create a separate VAT registration obligation.
This matters because the VAT rules include circumstances where a business must register based on the value of taxable supplies it expects to make during the following 30-day period.
What Happens If the Business Exceeds £90,000?
If a business exceeds the VAT registration threshold under the rolling 12-month test, it generally needs to register for VAT.
The registration deadline and effective registration date depend on the circumstances.
The business should not assume that it can simply wait until the end of the accounting year.
The registration process should be handled promptly once the obligation arises.
HMRC’s official guidance sets out the registration rules and deadlines that apply to businesses exceeding the threshold.
A business that has crossed the threshold should establish:
- Date the threshold was exceeded
- Amount of taxable turnover
- Effective VAT registration date
- VAT treatment of sales from the effective date
- Invoicing requirements
- VAT accounting method
- VAT return obligations
- Record-keeping requirements
What Happens If You Expect to Exceed the Threshold Soon?
There is another important VAT registration test.
A business may need to register if it expects the value of its taxable supplies in the next 30-day period alone to exceed the VAT registration threshold.
This can occur when a business receives a major contract or large order.
For example, a business with £70,000 of rolling taxable turnover might sign a £100,000 taxable contract that will be supplied during the next month.
The business should not assume that it can continue operating without VAT registration simply because the previous 12 months were below £90,000.
The expected taxable supplies test can apply in circumstances such as this.
Because the consequences of getting the effective date wrong can be significant, businesses facing a sudden large contract should seek professional VAT advice before issuing invoices.
Check Your Sales Categories Before Registering
A business approaching the threshold should review every major revenue stream.
Create a list of:
- Products
- Services
- Subscriptions
- Consulting
- Training
- Digital products
- Delivery charges
- Commission income
- Marketplace sales
- Other business income
Then identify the VAT treatment of each category.
For example:
| Revenue Type | Possible VAT Treatment |
|—|—|
| Standard business services | Standard-rated in many cases |
| Eligible zero-rated goods | Zero-rated |
| Certain qualifying services | Could be exempt depending on circumstances |
| International supplies | Treatment depends on customer, service and place of supply |
| Non-business receipts | May be outside scope |
The table is illustrative. The correct VAT treatment must be determined from the actual goods or services and the transaction circumstances.
A business should not rely on a generic VAT category simply because a competitor uses it.
Check Whether Your Customers Are Businesses or Consumers
VAT registration can affect pricing differently depending on the customer base.
A business selling mainly to VAT-registered companies may be able to charge VAT without the same direct effect on the customer’s final cost because the customer may be able to recover input VAT, subject to the normal rules.
A business selling mainly to consumers may face a different commercial situation.
For example:
Current price: £100
If VAT is added at 20%, customer price becomes £120.
Alternatively, if the business maintains a £100 VAT-inclusive price, the business does not simply receive £100 of net sales. The VAT element needs to be accounted for.
This makes pricing strategy important.
A business approaching VAT registration should model the effect before registration rather than changing prices without analysis.
Review Your Pricing Strategy
VAT registration does not automatically mean that every price should increase by 20%.
The commercial impact depends on:
- Customer type
- Competitor pricing
- Gross margins
- Product costs
- Ability to recover input VAT
- Market positioning
- Existing contracts
- Price sensitivity
For example, a B2B consultancy may have more flexibility to show prices plus VAT than a consumer-facing retailer.
A consumer ecommerce business may need to absorb some of the VAT in its existing prices to remain competitive.
The correct decision depends on the business model.
Before registration, calculate several scenarios.
Scenario A: Add VAT to existing prices
Net price: £100
VAT at 20%: £20
Customer pays: £120
Scenario B: Keep customer price at £100
VAT element at 20% VAT-inclusive pricing: £16.67
Net sales: £83.33
The difference between these scenarios can have a significant effect on margins.
Review Existing Contracts
A business with long-term contracts should review whether prices are:
- VAT inclusive
- VAT exclusive
- Subject to VAT if applicable
- Fixed regardless of tax status
- Adjustable if VAT becomes payable
This can become important when the business is approaching the registration threshold.
A contract stating £10,000 may not clearly explain whether the amount is exclusive or inclusive of VAT.
The business should review its terms and conditions and, where necessary, obtain legal or accounting advice before registration.
Review Your Invoicing System
Once VAT registered, invoices need to contain the required VAT information.
The business should make sure its invoicing software can:
- Apply VAT rates correctly
- Calculate VAT
- Show VAT separately where required
- Include the business’s VAT registration number
- Produce compliant invoices
- Maintain invoice records
- Support VAT reporting
Do not wait until the first VAT invoice needs to be issued before testing the software.
A business should configure its accounting system before the effective registration date.
Check Your Accounting Software
A VAT registration is an appropriate time to review accounting software.
The system should support:
- VAT coding
- VAT return preparation
- Bank feeds
- Sales invoices
- Purchase invoices
- Expense records
- Credit notes
- Digital records
- Reporting
- MTD where applicable
If the business currently uses spreadsheets, it should assess whether the system can handle the additional VAT reporting requirements efficiently.
AccountancyNet provides accounting and bookkeeping support for UK businesses that need help preparing financial records and managing VAT-related processes.
Review Your Expenses and Input VAT
VAT registration can allow a business to recover eligible input VAT on qualifying business purchases, subject to the relevant VAT rules.
This makes expense records particularly important.
Review:
- Supplier invoices
- Software subscriptions
- Professional fees
- Equipment
- Office costs
- Advertising
- Business travel
- Stock purchases
- Utilities
Not every business cost includes recoverable VAT.
A valid VAT invoice or appropriate supporting evidence is important for many input VAT claims.
The business should therefore ensure that suppliers provide appropriate VAT documentation where VAT is charged.
Check Your Historic Purchases
When a business registers for VAT, it may be possible to reclaim certain VAT incurred before registration, subject to specific rules and time limits.
The treatment differs between goods and services.
Goods that are still held or being used by the business at registration can be subject to different rules from services purchased before registration.
Businesses should therefore review previous invoices rather than assuming that all historical VAT can be reclaimed.
Keep the original invoices and supporting records.
An accountant can review the purchases and determine which items may qualify under the applicable pre-registration VAT rules.
Review Your Stock
Retail and ecommerce businesses approaching VAT registration should review their stock records.
Check:
- Quantity held
- Purchase cost
- Supplier
- Purchase date
- VAT on purchase invoices
- Stock currently available
- Damaged or obsolete stock
If eligible pre-registration VAT can be reclaimed on qualifying goods, accurate stock records can make the process easier.
A stock reconciliation also helps establish a reliable starting point for future VAT accounting.
Review Your Business Bank Account
VAT registration creates a tax liability that should be planned for.
Once VAT is collected from customers, that money is not simply additional business income.
A portion may ultimately need to be paid to HMRC after accounting for eligible input VAT and other adjustments.
A business should therefore monitor:
- VAT collected
- Input VAT
- Expected VAT liability
- VAT payment dates
- Cash reserved for VAT
A dedicated savings account can be useful for some businesses to set aside money for future VAT payments.
The exact amount to reserve depends on the business’s VAT position.
Do Not Treat VAT Collected as Profit
This is a common cash-flow mistake.
Suppose a business charges:
Net sale: £1,000
VAT: £200
Customer pays: £1,200
The £200 VAT is not ordinary business revenue.
It represents VAT collected from the customer, subject to the relevant VAT accounting.
If the business spends the entire £1,200 without considering its VAT liability, it may face a cash-flow problem when the VAT return is due.
Businesses approaching registration should therefore adjust their cash-flow planning before the effective VAT date.
Review Your Bookkeeping Frequency
Before VAT registration, monthly bookkeeping may have been sufficient for a small business.
After registration, more frequent bookkeeping can become useful.
The appropriate frequency depends on transaction volume, but businesses should avoid leaving VAT records until immediately before the filing deadline.
Regular bookkeeping allows the business to:
- Identify missing invoices
- Correct VAT coding errors
- Reconcile bank accounts
- Review input VAT
- Check sales VAT
- Investigate unusual transactions
- Forecast VAT liabilities
- Prepare accurate returns
The higher the transaction volume, the greater the benefit of keeping records current.
Check VAT Codes
Accounting software commonly uses VAT codes to determine how transactions appear on the VAT return.
Incorrect codes can produce incorrect VAT calculations.
Review common categories such as:
- Standard-rated purchases
- Standard-rated sales
- Zero-rated sales
- Exempt transactions
- Outside-scope transactions
- Reverse-charge transactions
- Imports
- International sales
The exact codes depend on the software.
Do not choose a VAT code based only on the name of the supplier.
The VAT treatment depends on the underlying transaction.
Review Overseas Sales
Businesses selling internationally need additional checks before VAT registration.
Consider:
- Customer location
- Goods location
- Where goods are dispatched from
- Value of consignments
- Customer type
- Marketplace involvement
- Import and export arrangements
- Relevant VAT or overseas tax obligations
For example, a UK ecommerce business selling to customers in the EU may have obligations that are separate from ordinary UK domestic sales.
VAT registration in the UK does not automatically resolve overseas VAT obligations.
International ecommerce businesses should review their cross-border sales separately.
Review Overseas Purchases
Buying services or goods from overseas suppliers can also create VAT considerations.
Common examples include:
- Software subscriptions
- Advertising
- Cloud services
- Professional services
- Stock
- Equipment
The treatment can depend on whether the purchase is goods or services, where the supplier is established and where the supply takes place.
Reverse-charge rules may apply to certain services received from overseas suppliers.
A business approaching VAT registration should review its major overseas suppliers before the first VAT return.
Consider the VAT Accounting Scheme
VAT-registered businesses may have different VAT accounting options depending on their eligibility.
The appropriate scheme can affect cash flow, administration and how VAT is reported.
Possible considerations include:
- Standard VAT accounting
- Cash Accounting Scheme
- Flat Rate Scheme
- Annual Accounting Scheme
Eligibility requirements and commercial suitability vary.
A business should not choose a VAT scheme simply because it appears easier.
For example, the Cash Accounting Scheme may have cash-flow benefits for certain businesses because VAT is generally accounted for based on payments rather than invoices, subject to the scheme rules.
The Flat Rate Scheme has specific eligibility conditions and may produce different results depending on the business’s costs and sector.
Professional advice can help determine whether a particular scheme is appropriate.
Review Whether the Flat Rate Scheme Is Suitable
The Flat Rate Scheme is designed for certain smaller VAT-registered businesses.
Instead of calculating input VAT in the same way as standard VAT accounting, the business applies a fixed percentage to relevant turnover, subject to the scheme’s rules.
The percentage depends on the business sector.
There are also special rules for businesses that meet the definition of a limited cost trader.
A business should calculate the actual financial impact before choosing the scheme.
A lower administrative burden does not necessarily mean a lower tax cost.
Consider Cash Accounting
Cash accounting can be useful for eligible businesses where customer payment timing creates cash-flow pressure.
Under the scheme, VAT is generally accounted for when payment is received and when purchases are paid, rather than simply when invoices are issued or received.
This can be particularly relevant to businesses with longer customer payment terms.
However, eligibility requirements and exceptions apply.
A business should compare the scheme with standard VAT accounting before making a decision.
Understand VAT Return Frequency
Once registered, the business will normally need to submit VAT returns according to its assigned VAT accounting period.
Many businesses submit quarterly VAT returns.
The return reports relevant VAT figures and calculates the amount payable to or recoverable from HMRC.
The business needs to maintain accurate records throughout the VAT period rather than attempting to reconstruct transactions at the deadline.
Prepare for Making Tax Digital for VAT
VAT-registered businesses must follow Making Tax Digital for VAT requirements where applicable.
This includes keeping required records digitally and submitting VAT returns through compatible software.
A business approaching the VAT threshold should therefore consider whether its existing bookkeeping system can support digital VAT compliance.
AccountancyNet provides Making Tax Digital support to businesses that need assistance with digital accounting and compliance.
The transition to VAT registration is easier when the bookkeeping system is already structured digitally.
Keep VAT Records Organised
A VAT-registered business should maintain records supporting:
- Sales
- Purchases
- VAT charged
- VAT paid
- Credit notes
- Import VAT
- Reverse-charge transactions
- VAT adjustments
- VAT returns
- VAT payments
The records should allow the VAT return figures to be traced back to the underlying transactions.
This is important if HMRC asks questions about the figures.
Review Your Credit Notes
Credit notes can affect VAT.
If a customer receives a refund or price adjustment, the VAT treatment needs to be reflected correctly.
Businesses should retain:
- Original invoice
- Credit note
- Reason for adjustment
- Customer details
- VAT amount
The accounting system should link the credit note to the original transaction where practical.
Review Bad Debts
A business may have customers who do not pay their invoices.
Bad debt relief can potentially apply to qualifying unpaid debts under specific VAT rules.
The business should keep appropriate evidence and follow the required conditions.
Do not automatically remove VAT from every unpaid invoice.
Bad debt relief has specific requirements.
Check Your VAT Registration Date
Once the business is required to register, the effective date matters.
The date can depend on whether the registration obligation arose because the rolling 12-month threshold was exceeded or because the business expected to exceed the threshold in the next 30 days.
The business should record:
- Date threshold test was triggered
- Relevant turnover calculation
- Registration deadline
- Effective registration date
- Invoices affected
- VAT accounting start date
Incorrectly assuming the registration date can result in invoices being issued without VAT when VAT should have been accounted for.
What Happens to Existing Customers?
Existing customers should be considered before VAT registration.
If the business has recurring customers, communicate pricing changes clearly.
For B2B customers, invoices may need to show VAT separately.
For consumer customers, the business needs to decide how prices will be displayed and whether existing prices will change.
Review:
- Website pricing
- Online checkout
- Price lists
- Contracts
- Quotes
- Subscription plans
- Recurring invoices
- Sales proposals
This is particularly important for ecommerce businesses where thousands of product prices may need updating.
Review Your Website and Ecommerce Platform
A VAT registration can require changes to the online store.
Check:
- Product prices
- VAT display
- Checkout calculations
- VAT invoices
- Customer receipts
- Shipping charges
- Customer location rules
- VAT registration number
- Accounting integration
The exact configuration depends on the ecommerce platform.
Test the checkout process before the VAT registration date.
A pricing error affecting hundreds of orders can create a significant bookkeeping correction later.
Check Your Marketplace Settings
Amazon, eBay, Etsy and other platforms can have their own tax settings.
Review:
- Seller VAT number
- Business address
- Tax settings
- VAT invoice settings
- Marketplace collection rules
- Customer location
- Product tax categories
Do not assume that changing a VAT number automatically completes all tax configuration.
The platform settings should be tested and reconciled against the accounting system.
Review Your Terms and Conditions
The business’s terms should clearly explain pricing and taxes.
Consider whether prices are:
- Inclusive of VAT
- Exclusive of VAT
- Subject to VAT where applicable
This is particularly important for service businesses quoting fixed prices.
A quote of £5,000 can have a different commercial result depending on whether £5,000 is VAT-inclusive or VAT-exclusive.
Prepare Staff for VAT Changes
If the business has employees, bookkeepers or sales staff, they should understand the new VAT process.
Training may cover:
- VAT invoices
- Expense receipts
- Supplier invoices
- Customer refunds
- Credit notes
- VAT codes
- Mileage claims
- Business expenses
- Purchase approvals
Staff should know that an ordinary receipt may not contain enough information to support an input VAT claim in every circumstance.
Check Your Payroll Separately
VAT registration does not directly change PAYE or National Insurance requirements.
However, a growing business approaching VAT registration may also be increasing its workforce.
Review payroll separately:
- Employees
- Contractors
- PAYE
- National Insurance
- Workplace pension
- Payroll records
AccountancyNet provides payroll services for businesses that need payroll support as they grow.
Keeping VAT and payroll processes organised separately helps prevent one compliance area from being overlooked while focusing on another.
Review Your Business Structure
A business approaching £90,000 turnover should also consider whether its current structure remains appropriate.
A sole trader and limited company have different tax and accounting responsibilities.
However, VAT registration itself does not require a business to become a limited company.
The decision to incorporate should be based on factors such as:
- Tax position
- Profit level
- Liability
- Administration
- Commercial requirements
- Future growth
- Investment
- Director responsibilities
Do not incorporate solely because VAT registration is approaching.
Do Not Split the Business to Avoid VAT
Businesses should not artificially separate activities or entities simply to avoid VAT registration.
HMRC has rules concerning artificial separation and whether businesses are genuinely separate.
If several businesses are closely connected and economically or financially linked, the VAT registration position may require careful analysis.
A business should seek professional advice before restructuring its activities with VAT registration in mind.
Monitor Turnover With a Monthly VAT Dashboard
A simple dashboard can make VAT monitoring easier.
Track:
| Month | Taxable Turnover | Rolling 12-Month Total | Distance From £90,000 |
| January | £7,000 | £70,000 | £20,000 |
| February | £7,500 | £75,000 | £15,000 |
| March | £8,000 | £80,000 | £10,000 |
| April | £9,000 | £86,000 | £4,000 |
| May | £7,000 | £89,000 | £1,000 |
| The figures above are illustrative. | |||
| The dashboard should be updated every month and should use the correct taxable turnover calculation. | |||
| A business with seasonal sales should pay particular attention to months where turnover can increase sharply. |
What Growing Businesses Should Check at £70,000
At £70,000, the business has significant room below the current threshold but should still establish a reliable monitoring process.
Check:
- Accounting software
- Sales categories
- Rolling turnover
- Pricing
- Bookkeeping frequency
- Customer types
- International sales
- Expected growth
The purpose is preparation rather than immediate registration.
What Growing Businesses Should Check at £80,000
At £80,000:
- Start monthly VAT threshold reviews.
- Confirm taxable versus exempt turnover.
- Review upcoming contracts.
- Check pricing strategy.
- Review accounting software.
- Review VAT invoice capability.
- Identify overseas transactions.
- Review input VAT records.
- Discuss registration implications with your accountant.
What Growing Businesses Should Check at £85,000
At £85,000:
- Review turnover at least monthly and consider more frequent monitoring if sales are accelerating.
- Forecast the next 30 days.
- Review major contracts.
- Check expected invoices.
- Review customer pricing.
- Prepare VAT registration information.
- Review software.
- Review VAT codes.
- Plan cash flow.
- Consider whether a VAT accounting scheme may be suitable.
What Growing Businesses Should Check at £89,000
At £89,000:
- Verify the rolling 12-month calculation.
- Review every transaction contributing to taxable turnover.
- Confirm whether any transactions have been incorrectly categorised.
- Review expected sales for the next 30 days.
- Prepare for registration if the threshold is exceeded.
- Avoid issuing invoices without considering the VAT implications.
- Discuss the position with an accountant.
At this point, a single large taxable sale could materially change the position.
What If Turnover Falls Back Below £90,000?
A business that has registered for VAT does not automatically cease being registered when turnover falls below £90,000.
Deregistration has separate rules and thresholds.
The current UK VAT deregistration threshold is £88,000.
A business should not repeatedly register and deregister based on small changes in turnover.
The decision needs to follow the applicable HMRC rules and the actual circumstances.
Voluntary VAT Registration
A business below the mandatory threshold can choose to register voluntarily.
This may be appropriate in some circumstances.
Potential reasons include:
- Business customers expect VAT invoices.
- The business has significant VAT-bearing costs.
- The business wants to reclaim eligible input VAT.
- The business expects to exceed the threshold soon.
- VAT registration supports commercial credibility in a particular market.
Potential disadvantages can include: - Additional administration
- VAT return obligations
- Pricing considerations
- More complex bookkeeping
- Cash-flow management
A voluntary registration decision should therefore be based on the economics and administration of the business rather than simply registering because competitors are VAT registered.
Common VAT Threshold Mistakes
Mistake 1: Checking annual turnover only
VAT uses specific threshold tests, including a rolling 12-month test.
Mistake 2: Confusing profit with taxable turnover
VAT registration is not based on net profit.
Mistake 3: Ignoring zero-rated sales
Zero-rated taxable supplies can still count towards the registration threshold.
Mistake 4: Assuming every income source counts
Exempt and outside-scope transactions can have different treatment.
Mistake 5: Waiting until year-end
The VAT test can arise before the financial year ends.
Mistake 6: Forgetting the 30-day test
A business expecting a large taxable supply may need to consider the separate future-supplies test.
Mistake 7: Adding 20% to every price without analysis
The commercial impact depends on the customer and pricing model.
Mistake 8: Spending VAT collected
VAT collected should be considered a tax liability rather than ordinary profit.
Mistake 9: Applying incorrect VAT codes
Incorrect software coding can result in incorrect VAT returns.
Mistake 10: Assuming platforms handle everything
Ecommerce platforms can assist with tax calculations and collections but do not necessarily remove all obligations from the seller.

Frequently Asked Questions
What is the current UK VAT registration threshold?
The current VAT registration threshold is £90,000 of taxable turnover. The deregistration threshold is £88,000.
Is the VAT threshold based on profit?
No. VAT registration is generally based on taxable turnover rather than net profit.
Is the VAT threshold based on calendar-year sales?
No. The main compulsory registration test uses taxable turnover over a rolling 12-month period.
Do zero-rated sales count towards the VAT threshold?
Yes, zero-rated taxable supplies can count towards taxable turnover even though the VAT rate charged is 0%.
Do exempt sales count towards the threshold?
Exempt supplies are treated differently from taxable supplies and should not automatically be included in the same way.
What happens if I exceed £90,000?
If the relevant VAT registration test is met, the business generally needs to register with HMRC and account for VAT from the applicable effective date.
Can I voluntarily register below £90,000?
Yes, businesses below the mandatory threshold can generally apply for voluntary VAT registration, subject to the relevant rules.
Should I add 20% to my prices after registering?
Not necessarily. The commercial decision depends on the customer base, existing pricing, competition and whether prices are quoted inclusive or exclusive of VAT.
Can I reclaim VAT on purchases made before VAT registration?
Potentially. Specific rules and time limits apply to qualifying goods and services purchased before registration.
Does VAT registration mean I need an accountant?
No, but professional support can be useful when a business has complex sales, international transactions, ecommerce activity, large amounts of input VAT or uncertainty about registration dates.
Does VAT registration automatically mean I need to become a limited company?
No. VAT registration and incorporation are separate decisions.
Can I avoid VAT registration by creating another business?
Artificial separation of activities to avoid VAT can create significant compliance issues. The commercial and VAT position should be reviewed professionally before changing the business structure.
Final Thoughts
Approaching the VAT threshold should trigger preparation rather than panic.
The most important step is to monitor taxable turnover using the correct rolling 12-month calculation. A business should distinguish taxable supplies from exempt and outside-scope income, include relevant zero-rated sales, and consider the separate rules that can apply when taxable supplies are expected to exceed the threshold in the next 30 days.
Once registration becomes necessary, the business needs to consider its effective registration date, pricing, contracts, invoices, bookkeeping software, VAT codes, input VAT, cash flow, international transactions and reporting procedures.
The current UK VAT registration threshold is £90,000, but the threshold itself is only one part of VAT compliance. The quality of the underlying bookkeeping determines whether the business can calculate its position accurately and submit correct VAT returns.
