Your first year end accounts can feel complicated when you have spent the year focused on winning customers, delivering work and keeping the business running. However, preparing your records early can make the accounting process much easier and help you avoid last minute problems.
For a UK limited company, annual accounts are prepared from the company’s financial records at the end of its financial year. These accounts report the company’s financial position and performance and are used for reporting to Companies House and HMRC.
The first year can be particularly important because you are establishing the accounting systems and habits that you will use in future years. Getting the basics right now can make every subsequent year end more straightforward.
Whether you have recently incorporated a limited company or are approaching your first accounting year end, this guide explains what to prepare, what records to check and how to work effectively with your accountant.
What Are First Year End Accounts?
Year end accounts are financial statements prepared for a business at the end of its accounting period.
For a limited company, statutory accounts generally include a balance sheet and profit and loss account, together with relevant notes and other information depending on the company’s size and circumstances.
The profit and loss account shows the company’s income, costs and resulting profit or loss during the accounting period.
The balance sheet provides a snapshot of what the company owns, what it owes and what is owed to it at the end of the financial year.
These figures are not simply a summary of your bank balance. Your accountant may need to make year end adjustments so the accounts accurately reflect the company’s financial position.
When Is Your First Accounting Year End?
One of the first things to establish is your company’s accounting reference date.
When a company is incorporated, Companies House normally sets its first accounting reference date as the last day of the month in which the anniversary of incorporation falls.
For example, if your company was incorporated on 15 September 2025, its first accounting reference date would normally be 30 September 2026.
Your first accounts can therefore cover more than 12 months. GOV.UK gives the example of a company incorporated on 11 May whose first accounts cover the period from incorporation until 31 May of the following year.
Do not assume that your first year end is simply 12 months after you started trading. Check the company’s accounting reference date and the relevant Corporation Tax accounting period.
What Is the Difference Between Accounts and Your Tax Return?
It is easy for a new business owner to assume that year end accounts and the Corporation Tax return are exactly the same thing.
They are closely connected, but they are not identical.
Your company accounts describe the company’s financial performance and position. The Corporation Tax return uses the relevant accounting information to calculate the company’s taxable profit and Corporation Tax position.
There are also different filing deadlines.
For a private limited company, annual accounts normally need to be filed with Companies House within nine months of the financial year end. Corporation Tax is normally due nine months and one day after the end of the Corporation Tax accounting period, while the Company Tax Return is normally due within 12 months of the end of that accounting period.
This is why knowing your dates early matters.
First Year End Accounts Checklist
Before sending your records to an accountant, work through a basic year end checklist.
1. Make Sure All Sales Are Recorded
Start by checking that every sale made during the accounting period has been recorded.
Look at your:
- Sales invoices
- Receipts
- Card payments
- Cash sales
- Online payments
- Ecommerce platforms
- Customer refunds
- Credit notes
If you invoice customers, compare your bookkeeping records against your invoicing system.
If you operate an ecommerce business, do not rely solely on the amount that reaches your bank account. Platform fees, refunds, payment processing charges and other deductions can mean that bank deposits do not represent your gross sales.
The aim is to establish a complete and accurate record of business income.
2. Reconcile Your Business Bank Account
Bank reconciliation should be one of the most important parts of your first year end preparation.
Compare the transactions recorded in your accounting software with the actual bank statements.
Look for:
- Missing transactions
- Duplicate transactions
- Unexplained payments
- Unrecorded bank charges
- Transfers entered incorrectly
- Customer payments that have not been matched
- Payments made personally on behalf of the company
Ideally, your bookkeeping should already be reconciled regularly. If it has not been, year end is a good opportunity to bring the records up to date.
For a limited company, keeping company finances separate from personal finances is particularly important because the company is a separate legal entity. GOV.UK recommends keeping business banking separate from personal banking.
3. Check Your Business Expenses
Go through your expenses and make sure they are properly recorded and supported by appropriate documentation.
Common categories may include:
- Office costs
- Software subscriptions
- Professional fees
- Advertising
- Travel
- Business insurance
- Equipment
- Telephone and internet costs
- Rent
- Training
- Stock and materials
Do not assume that every expense paid from a business bank account automatically receives the same tax treatment.
Your accountant can review the transactions and determine how they should be treated in the accounts and tax computation.
4. Gather Your Receipts and Invoices
Your bookkeeping entries should be supported by appropriate evidence.
For example, a bank statement can show that £500 left your account, but it may not explain whether the payment was for advertising, equipment, personal spending or something else.
Keep supplier invoices, receipts, contracts, payment confirmations and other relevant documents.
Companies are required to maintain accounting records that show and explain their transactions, including money received and spent, assets and liabilities.
5. Review Outstanding Customer Invoices
If customers still owe your company money at the year end, make sure your accounting records show the outstanding amounts.
Create a list of unpaid invoices and check whether the amounts are still recoverable.
This can help your accountant determine the correct year end treatment.
It can also give you a useful snapshot of your company’s debtor position.
A business can be profitable on paper while experiencing cash flow pressure because customers have not yet paid their invoices.
6. Check What You Owe Suppliers
The same principle applies to supplier invoices.
You may have received goods or services before the year end but not yet paid the supplier.
Make sure these outstanding amounts are identified.
Your accountant may need this information when preparing the year end accounts.
This is one reason why simply looking at your bank balance is not enough to understand your company’s financial position.
7. Review Stock
If your business holds stock, you should establish the stock position at the year end.
This can include:
- Products held for sale
- Raw materials
- Packaging
- Components
- Work in progress
Accurate stock information can affect the figures reported in your accounts.
Companies that deal in goods have specific record keeping requirements around stock and stocktaking.
For a growing retail or ecommerce business, a proper year end stock process can therefore be particularly important.
8. Record Business Assets
Make a list of significant assets owned by the company.
These might include:
- Computers
- Machinery
- Vehicles
- Furniture
- Specialist equipment
- Fixtures
- Other long term business assets
Include information such as the purchase date, cost and relevant supporting documentation.
Your accountant can then determine the appropriate accounting treatment and whether capital allowances or other tax considerations may apply.
9. Check Company Loans and Finance
If you borrowed money to start or expand the company, provide details of the finance arrangements.
This could include:
- Business loans
- Director loans
- Hire purchase
- Asset finance
- Overdrafts
- Other financing arrangements
Provide loan statements where available.
The year end accounts need to reflect relevant liabilities and balances accurately.
10. Review the Director’s Loan Account
If you are a company director and have taken money from the company or personally paid company expenses, the director’s loan account may need attention.
This is an area where new company owners can easily become confused because company money and personal money should not simply be treated as interchangeable.
Give your accountant complete information about money you have taken from or paid into the company.
Do not attempt to hide or ignore unusual transactions.
A complete record allows the correct accounting and tax treatment to be considered.
What Documents Should You Give Your Accountant?
The exact information required depends on the business, but a useful first year end pack can include:
| Document or Information | Why It Matters |
| Business bank statements | Supports bank reconciliation |
| Sales invoices | Supports recorded income |
| Purchase invoices | Supports business expenditure |
| Receipts | Provides evidence of costs |
| VAT returns | Helps reconcile VAT balances |
| Payroll reports | Supports wages and payroll liabilities |
| Loan statements | Supports finance balances |
| Asset purchase details | Helps identify business assets |
| Stock valuation | Supports year end stock figures |
| Debtor list | Shows amounts owed to the company |
| Creditor list | Shows amounts owed by the company |
| Ecommerce reports | Helps reconcile online sales |
| Director loan information | Supports director related balances |
| Previous accounting information | Helps establish opening balances |
| The better organised this information is, the easier it is for your accountant to identify discrepancies and prepare the accounts efficiently. |
What Year End Adjustments Might Be Needed?
Your bookkeeping records are not necessarily the final accounts.
An accountant may need to make adjustments so the accounts reflect the correct accounting period and financial position.
These can include:
Accruals
An accrual may be needed where the company has received a service or incurred a cost before year end but has not yet received or paid the relevant invoice.
Prepayments
A prepayment can arise when a business has paid for something in advance that relates partly to a future accounting period.
Depreciation
Certain business assets may need to be accounted for over their useful economic life rather than treating the entire purchase price as an immediate accounting expense.
Bad Debts
If a customer balance is unlikely to be recovered, your accountant may need to consider the appropriate treatment.
Stock Adjustments
If the company holds stock, the year end accounts may need to reflect the appropriate stock figure.
Corporation Tax
The accounts and tax computation need to be considered together so the company’s Corporation Tax position can be calculated correctly.
These adjustments are one reason professional year end accounts preparation involves more than simply exporting a profit and loss report from accounting software.
What Should a Small Business Do Before Its First Year End?
The best preparation starts months before the deadline.
A simple monthly routine can make the eventual year end process considerably easier.
Keep Bookkeeping Up to Date
Do not leave 12 months of transactions for your accountant to untangle at the end of the year.
Update your records regularly.
Monthly bookkeeping makes it easier to identify missing receipts, unusual transactions and discrepancies while they are still easy to investigate.
Keep Business and Personal Spending Separate
For a limited company, maintain a clear division between company and personal finances.
GOV.UK states that because a company is a separate legal entity, there must be a clear division between the company’s finances and those of its owners and directors.
A separate business bank account can make this much easier.
Save Documents Digitally
Instead of keeping receipts and invoices in different physical locations, use a consistent digital filing system.
You could organise documents by:
- Month
- Supplier
- Expense category
- Project
- Financial year
The exact system is less important than using it consistently.
Review Your Accounts Monthly
A monthly review can reveal issues before they become year end problems.
Look at:
- Revenue
- Gross profit
- Operating costs
- Outstanding invoices
- Cash flow
- VAT
- Payroll
- Unusual transactions
- Director balances
You do not need to be an accountant to benefit from understanding these numbers.
What If Your Records Are Incomplete?
Do not wait until the filing deadline if your records are missing information.
Start by identifying the gaps.
For example, you might discover:
- Three months of bank transactions have not been reconciled
- Several supplier invoices are missing
- Some customer invoices were never entered
- Personal transactions were mixed with company spending
- Ecommerce sales do not match bank deposits
- Stock records are incomplete
The next step is to reconstruct the information using reliable evidence.
Bank statements, supplier invoices, customer records, payment platform reports and accounting software can all help.
Companies are required to keep accounting records that are sufficient to show and explain transactions and allow directors to ensure their accounts comply with relevant requirements.
If you are dealing with several months of incomplete bookkeeping, professional help can save significant time and reduce the risk of submitting inaccurate figures.
What Happens After Your First Year End Accounts Are Prepared?
Once the accounts are prepared, the company may need to use them for several purposes.
For a private limited company, statutory accounts generally need to be provided to shareholders and filed with Companies House and HMRC as part of the Company Tax Return.
Your accounts can also help you understand:
- How profitable the business was
- How much the company owns
- How much it owes
- How much customers owe
- How much cash is available
- Whether expenses are increasing
- Whether the business is ready to grow
This is where year end accounts become more than a compliance exercise.
They provide a financial picture that can help you make better business decisions during the following year.
What Are the First Year Accounts Deadlines?
For many private limited companies, the standard deadline for filing annual accounts with Companies House is nine months after the financial year end.
However, the first accounting period can have different rules.
For a company’s first accounts, if the accounts cover more than 12 months, a private company generally has 21 months from incorporation to deliver them to Companies House, subject to the applicable rules.
Corporation Tax deadlines are separate.
Corporation Tax is generally due nine months and one day after the end of the accounting period, while the Company Tax Return is generally due 12 months after the end of that accounting period.
Because deadlines can depend on your company’s specific circumstances, check the dates applicable to your company rather than relying on a generic calendar reminder.
What Happens If You File Your Accounts Late?
Late filing can result in penalties.
Companies House explains that companies must file their accounts on time and that there can be serious consequences for failing to comply with filing responsibilities.
The practical lesson is simple: do not wait until the deadline to discover that your bookkeeping is incomplete.
Give yourself and your accountant enough time to investigate missing information, prepare the accounts, review the figures and file the necessary documents.
Do Small Companies Need an Accountant for Year End Accounts?
A company does not necessarily have to use a professional accountant to prepare its accounts. However, directors remain responsible for ensuring that the company meets its legal and reporting responsibilities.
For a straightforward business, accounting software may help with day to day bookkeeping.
However, year end accounts can involve adjustments, tax considerations, balance sheet items and filing requirements that are not always obvious to someone preparing accounts for the first time.
An accountant can also provide a useful independent review of your records and identify issues before they become expensive problems.

First Year End Accounts: Common Mistakes to Avoid
Leaving Bookkeeping Until the Last Minute
Year end should be a review process, not the first time anyone looks at the bookkeeping in months.
Treating the Bank Balance as Profit
Your bank balance does not tell you your accounting profit.
Money may relate to loans, VAT, unpaid invoices, capital purchases or other transactions.
Mixing Personal and Company Expenses
This makes reconciliation harder and can create confusion around director balances.
Forgetting Outstanding Invoices
Unpaid invoices can still be relevant to the accounts even if the customer has not paid.
Ignoring Small Transactions
A large number of small transactions can become significant when added together.
Assuming Accounting Software Does Everything
Software can improve record keeping, but it does not remove the need for accurate data and appropriate accounting decisions.
Missing Filing Deadlines
A well prepared set of accounts is only useful if it is filed correctly and on time.
