MTD for multiple businesses can create confusion for sole traders who operate more than one income source. If you run multiple businesses, HMRC generally expects you to keep accurate digital records for each relevant business activity and ensure your quarterly updates correctly reflect the income and expenses connected to each activity.
Many entrepreneurs now operate more than one business at the same time. A consultant may also run an online store. A tradesperson may have a separate property income stream. A freelancer may provide different services under separate brands.
While managing multiple income sources can create new opportunities, it also creates additional bookkeeping responsibilities. Under Making Tax Digital for Income Tax, accurate digital records are essential to ensure each business activity is reported correctly.
This guide explains how MTD works when you have more than one business, whether you need separate records, how quarterly updates are submitted and how professional bookkeeping support can help you stay compliant.
Quick Answer: Do You Need Separate MTD Records for Multiple Businesses?
Yes, in most cases you should keep separate digital records for each business activity.
HMRC needs to understand the income and expenses generated by each trade or business. Keeping separate records helps ensure:
- Income is reported under the correct business activity
- Expenses are allocated correctly
- Quarterly updates contain accurate information
- Year end tax calculations are easier to complete
- Business performance can be reviewed separately
For example, if you operate a web design business and an ecommerce store, combining all transactions into one set of records can make it difficult to identify which expenses belong to which activity.
Separate records create a clearer picture for both you and HMRC.
What Is MTD for Multiple Businesses?
MTD for multiple businesses refers to the process of using Making Tax Digital compatible software when an individual has more than one qualifying business activity.
Making Tax Digital for Income Tax applies to individuals who receive qualifying self employment or property income above the relevant threshold.
Instead of keeping traditional paper records or disconnected spreadsheets, affected taxpayers must maintain digital records and send updates to HMRC through compatible software.
When someone operates multiple businesses, each business may need its own digital bookkeeping records.
The purpose is not to create unnecessary administration. It is to ensure that income and expenses can be accurately linked to the correct activity.
For example:
A Manchester based entrepreneur operates:
- A freelance marketing consultancy
- An online clothing business
The consultancy has:
- Client invoices
- Software subscriptions
- Professional costs
The clothing business has:
- Stock purchases
- Packaging costs
- Shipping expenses
- Marketplace fees
These are two different business activities and should not simply be merged into one unclear record.
Why Separate Records Matter Under MTD
Accurate separation is important because different businesses often have different financial patterns.
One business may generate high turnover with low expenses.
Another may have significant costs before becoming profitable.
Combining everything together can hide important information.
Separate records help with:
Accurate Quarterly Updates
MTD quarterly updates are based on totals generated from digital records.
If transactions are mixed together, the quarterly figures may not accurately represent each business.
Correct Expense Allocation
Some expenses clearly belong to one business.
For example:
A photographer purchases a professional camera.
That expense may relate directly to photography services.
However, if the same person also operates a marketing consultancy, the camera expense should not automatically be allocated to both activities.
Easier Tax Preparation
At the end of the tax year, your accountant needs accurate information to prepare your final tax position.
Separate records reduce the time required to identify:
- Business income
- Allowable expenses
- Private use adjustments
- Capital purchases
- Missing transactions
How Does MTD Work If You Have Two Self Employed Businesses?
If you operate two self employed businesses, you should maintain digital records for each business.
For example:
Business One: Plumbing Services
Records may include:
- Customer invoices
- Materials purchased
- Vehicle costs
- Tools
- Insurance
- Subcontractor payments
Business Two: Property Maintenance Training
Records may include:
- Course income
- Website costs
- Advertising expenses
- Software subscriptions
- Professional fees
Although both activities belong to the same individual, they are separate business activities.
Each should have clear records showing the income and expenses connected with that activity.
Your accounting software may allow you to manage multiple businesses within one account, but each business should usually have separate bookkeeping records or files.
How Do MTD Quarterly Updates Work With Multiple Businesses?
MTD quarterly updates are submitted through compatible software.
If you have multiple businesses, the software must be able to identify the relevant income and expense information for each activity.
Quarterly updates generally include:
- Reporting period dates
- Income totals
- Expense totals
- Relevant business categories
The updates are usually cumulative.
This means each submission updates HMRC with totals from the beginning of the tax year up to the reporting period.
For example:
A sole trader has:
- A consulting business
- An online retail business
The first quarterly update includes figures from the start of the tax year until the first reporting deadline.
The second update includes updated cumulative figures covering the period from the start of the tax year until the second deadline.
Maintaining accurate records throughout the year makes this process significantly easier.

Examples of Multiple Businesses Under MTD
Understanding real examples can make the rules easier to apply.
Example 1: Freelancer With an Ecommerce Store
Sarah works as a freelance graphic designer in Manchester.
She also sells handmade products through an online marketplace.
Her design business includes:
- Client payments
- Adobe subscriptions
- Laptop equipment
- Website costs
Her ecommerce business includes:
- Product materials
- Packaging
- Delivery costs
- Marketplace fees
These activities should have separate records because the income and expenses relate to different business operations.
Example 2: Builder With Rental Income
Ahmed operates as a self employed builder.
He also owns a rental property.
His construction business includes:
- Tools
- Materials
- Vehicle costs
- Customer invoices
His property activity includes:
- Rental income
- Property repairs
- Management fees
- Finance costs
Self employment income and property income should be recorded separately because they are different sources of income.
Example 3: Consultant With Two Service Businesses
A business owner provides:
- Business consultancy
- Online training courses
Although both activities involve professional services, they may have different customers, costs and income patterns.
Separate records allow better reporting and easier tax preparation.
Can You Use One Accounting Software for Multiple Businesses?
Yes, many accounting platforms allow users to manage multiple businesses.
However, using one software platform does not mean all transactions should be combined.
The important requirement is maintaining accurate digital records.
A suitable setup may include:
- Separate company files
- Separate bank feeds
- Separate income categories
- Separate expense tracking
- Separate reporting
Before choosing software, businesses should check whether it supports their specific MTD requirements.
An accountant can help review whether your current system is suitable.
What Digital Records Should You Keep for Each Business?
Each business should maintain records showing the financial activity connected with that operation.
Important records include:
Income Records
Examples include:
- Sales invoices
- Customer payments
- Online marketplace reports
- Payment processor statements
- Rental income statements
- Commission records
Expense Records
Examples include:
- Supplier invoices
- Receipts
- Software subscriptions
- Advertising costs
- Insurance documents
- Professional fees
- Equipment purchases
Bank Records
You should maintain records of:
- Business bank transactions
- Credit card payments
- Payment gateway transactions
- Cash payments
- Refunds
Separate business bank accounts are recommended because they make bookkeeping significantly easier.
Common Mistakes When Managing Multiple Businesses Under MTD
Many business owners unintentionally create problems by mixing records.
Combining All Income Together
Different businesses should not simply be treated as one activity.
This can make reporting inaccurate.
Using One Bank Account for Everything
While possible in some circumstances, mixing personal and business transactions increases bookkeeping complexity.
Forgetting Secondary Income Streams
Some business owners remember their main activity but overlook smaller income sources.
Examples:
- Online sales
- Consultancy projects
- Rental income
- Side businesses
Allocating Expenses Incorrectly
An expense should be connected to the business activity it relates to.
Incorrect allocation can affect tax calculations.
Waiting Until the Quarterly Deadline
Trying to organise several businesses at the last minute creates unnecessary pressure.
Regular bookkeeping is a better approach.
Do Separate Businesses Need Separate Bank Accounts?
HMRC does not require every business activity to have a separate bank account.
However, separate accounts are often recommended.
Benefits include:
- Easier transaction matching
- Faster bookkeeping
- Fewer errors
- Clearer financial reporting
- Better business decision making
For businesses with multiple income streams, separating finances can save significant time.
How Bookkeeping Supports MTD Compliance
Good bookkeeping is the foundation of successful MTD compliance.
The quarterly submission is only as accurate as the records behind it.
Professional bookkeeping support can help businesses:
- Categorise transactions correctly
- Reconcile accounts
- Track multiple income streams
- Identify missing records

- Reduce administrative workload

MTD for Multiple Businesses and Self Assessment
