Running a UK limited company involves more than filing accounts and paying Corporation Tax. A company must also maintain records that show what money came into the business, what it spent, why transactions took place, and how the figures reported to HM Revenue and Customs (HMRC) were calculated. Good record keeping is not simply an administrative exercise. It gives directors evidence to support tax returns, makes year-end accounts easier to prepare, helps accountants work accurately, and gives the company something to rely on if HMRC opens a compliance check.

For most UK companies, the practical rule is to keep relevant accounting and tax records for at least six years from the end of the company financial year they relate to, although some records have different statutory periods and particular circumstances can require records to be retained for longer. This guide explains what records a UK company should keep, how long to retain them, and how founders can build a simple record-keeping system that works as the business grows.

What Are Tax Records?

Tax records are the documents and information a company uses to calculate and support its tax position. They can include financial documents such as:

• Sales invoices
• Purchase invoices
• Receipts
• Bank statements
• Expense records
• Payroll information
• VAT records
• Contracts
• Records of assets and equipment
• Loan documentation
• Accounting ledgers
• Records supporting tax deductions
• Company correspondence relevant to tax matters

HMRC expects companies to keep sufficient records to make a correct and complete Company Tax Return. For Corporation Tax purposes, companies must retain records and supporting documents that support their tax position. The important principle is that a record does not have to be labelled a "tax document" to matter for tax.

For example, a bank statement may not look like a tax record, but it can provide evidence that a business expense was actually paid. Similarly, a contract can help establish what a payment related to, while an invoice can demonstrate the amount, date and nature of a transaction.

What Tax Records Must a UK Company Keep?

There is no single document called a "tax records file". Instead, companies should maintain a complete trail of their financial activity.

1. Sales and Income Records

A company should keep records showing the money it receives from customers and other sources. Depending on the business, this could include:

• Sales invoices
• Credit notes
• Receipts
• Sales reports
• Till records
• Online payment reports
• Marketplace statements
• Contracts
• Customer payment records
• Records of other business income

HMRC's guidance specifically requires companies to keep records of money received by the company, including invoices, contracts, sales books and till rolls where relevant. For an ecommerce business, for example, the accounting trail might include Shopify or marketplace sales reports, payment processor statements and the company's bank statements. Keeping only the bank statement may not be enough to explain every transaction properly.

2. Purchase and Expense Records

Companies should keep evidence of money spent on business activities. Typical records include:

• Supplier invoices
• Receipts
• Purchase orders
• Delivery notes
• Expense claims
• Business credit card statements
• Supplier contracts
• Records of professional fees
• Travel and accommodation records
• Software subscriptions
• Advertising invoices
• Office expenses

HMRC requires records of receipts and expenses connected with company activities, as well as information about the matters to which those receipts and expenses relate. This last point is particularly important. A receipt showing that £500 was spent does not always explain why the company spent £500. A useful record-keeping system should therefore preserve enough information to establish the business purpose of the transaction.

3. Bank Statements and Financial Records

Company bank statements are among the most useful records a business can maintain. They help reconcile:

• Customer payments
• Supplier payments
• Tax payments
• Payroll
• Bank charges
• Loan repayments
• Director transactions
• Transfers between accounts

UK companies should keep company finances separate from the personal finances of directors and shareholders. GOV.UK specifically recommends using a business bank account to keep company and personal finances separate. For founders, this is one of the simplest habits that can prevent accounting problems later. If a director pays a company expense personally, the transaction should still be properly recorded rather than disappearing into personal banking records.

4. Accounting Records and Ledgers

A company also needs accounting records that bring individual transactions together into a coherent financial picture. These can include:

• General ledger
• Sales ledger
• Purchase ledger
• Cash book
• Trial balance
• Profit and loss records
• Balance sheet records
• Journal entries
• Stock records where relevant
• Fixed asset records

The purpose is not simply to produce attractive accounts. These records help explain how the figures in the company's accounts and tax returns were calculated. There is also an important distinction between Companies Act accounting requirements and tax record requirements.

For example, Companies House guidance states that private companies generally have a three-year statutory accounting-record retention period under the Companies Act, while tax rules generally require relevant company records to be retained for longer. For a private company, the six-year Corporation Tax requirement will therefore often be the more important practical retention period. When different rules apply to the same record, the safer approach is to retain it for the longest applicable period.

5. Corporation Tax Records

Corporation Tax records should allow the company to support the figures reported to HMRC. This includes records supporting:

• Turnover
• Allowable business expenses
• Capital expenditure
• Capital allowances
• Interest
• Losses
• Tax adjustments
• Company profits
• Tax payments
• Related transactions

HMRC's guidance says companies required to submit a Company Tax Return must generally retain records until the later of the applicable retention date and the completion of an enquiry into the relevant matters, subject to the specific rules. This means a company should not automatically destroy records as soon as six years have passed if another rule requires them to be retained longer.

6. VAT Records

VAT-registered companies have additional record-keeping responsibilities. VAT records include:

• VAT invoices issued
• VAT invoices received
• Credit notes
• Debit notes
• Purchase records
• Sales records
• VAT account
• Import and export documentation where applicable
• Records of VAT calculations
• Relevant business correspondence

HMRC says VAT-registered businesses generally need to keep VAT records for at least six years. Certain businesses using the VAT One Stop Shop or legacy Mini One Stop Shop arrangements may have a 10-year retention requirement. VAT records also have digital requirements. Businesses within Making Tax Digital for VAT generally need to maintain relevant VAT records digitally unless an exemption applies. This is especially important for companies using accounting software, ecommerce platforms and multiple payment providers.

7. PAYE and Payroll Records

If a company employs people or operates a PAYE scheme, it must maintain payroll records. These can include:

• Employee pay
• Income Tax deductions
• National Insurance deductions
• Payroll reports submitted to HMRC
• Payments made to HMRC
• Tax code notices
• Employee leave and sickness records
• Taxable benefits
• Taxable expenses
• Payroll Giving documents where applicable

HMRC currently requires employers to keep PAYE records for three years from the end of the tax year they relate to. Again, a company should consider whether another legal or tax requirement means a particular document needs to be retained for longer.

8. Records for Company Assets

Companies should maintain records for significant business assets. For example:

• Computers
• Machinery
• Vehicles
• Office equipment
• Property
• Business premises improvements
• Other capital assets

Keep documentation showing:

• What was purchased
• Purchase date
• Purchase price
• Supplier
• How the asset was used
• Disposal date, if applicable
• Disposal proceeds
• Related professional or transaction costs

Asset records can become particularly important when calculating capital allowances or determining the tax treatment of an asset sale. HMRC specifically notes that records relating to assets expected to last more than six years may need to be kept for longer than the standard six-year period.

9. Loan and Director Transaction Records

Company loans should be properly documented. This includes:

• Business loans
• Director loans
• Money introduced by shareholders
• Money withdrawn by directors
• Repayment records
• Loan agreements
• Interest calculations
• Bank documentation

Director loan accounts deserve particular attention because transactions between a company and its directors can have accounting and tax consequences. A simple spreadsheet entry saying "director paid £2,000" may not provide enough context. The records should make clear whether the amount was:

• A reimbursed business expense
• Salary
• Dividend
• Money introduced into the company
• A director's loan
• Something else

Clear documentation can prevent confusion when the accounts are prepared.

10. Records Supporting Tax Reliefs and Deductions

Tax deductions should be supported by evidence. If a company claims a deduction, keep the documentation explaining why the expense qualifies. Depending on the business, this could include evidence relating to:

• Research and development
• Professional training
• Business travel
• Capital expenditure
• Employer pension contributions
• Professional fees
• Charitable donations
• Bad debts
• Interest
• Business insurance

The more unusual or significant the deduction, the more important supporting evidence becomes. For example, if a startup claims a substantial R&D-related tax relief, it should maintain detailed evidence of the relevant projects, expenditure and eligibility rather than relying on a single accounting entry.

How Long Should a UK Company Keep Tax Records?

For most company tax and accounting records, six years is the key practical benchmark. GOV.UK states that companies generally need to keep records for six years from the end of the last financial year they relate to. Longer retention can apply where:

• A transaction covers more than one accounting period
• The company owns an asset expected to last more than six years
• A Company Tax Return was submitted late
• HMRC has started a compliance check

A useful summary is:

These are general rules rather than a substitute for checking the requirements that apply to a particular company.

Can Tax Records Be Stored Digitally?

Yes. Modern businesses can maintain many records electronically, provided the records remain accurate, accessible and usable when required. Digital records might include:

• PDF invoices
• Scanned receipts
• Bank statements
• Accounting software records
• Payroll reports
• Cloud storage
• Electronic contracts
• Email correspondence

The goal is not to accumulate thousands of files in a folder called "Accounts". The goal is to create a reliable audit trail. A useful digital structure might look like:

2026 → Sales → Expenses → Bank → Payroll → VAT → Corporation Tax → Assets → Loans

Within each folder, files can be organised by month or accounting period.

How Global Founders Can Manage Tax Records Remotely

For a founder living outside the UK, record keeping can become more complicated because documents may come from different countries, currencies and payment platforms. A practical system should centralise:

1. Company bank statements
2. Accounting records
3. Sales invoices
4. Supplier invoices
5. Tax correspondence
6. Payroll records
7. VAT records, if applicable
8. Company documents
9. Asset documentation
10. Accountant communications

Currency conversion should also be documented where transactions occur in currencies other than sterling. International founders should remember that UK company records are only one part of their potential tax obligations. Their personal country of residence and the countries where the business operates may create additional record-keeping requirements.

What Happens If Company Records Are Lost?

Accidents happen. A laptop can fail, cloud access can be lost, or paper records can be destroyed. If company records are lost, stolen or destroyed and cannot be replaced, GOV.UK says the company should do its best to recreate them, notify its Corporation Tax office and include relevant information in its Company Tax Return. This is why backups matter. A sensible company should maintain at least:

• Primary accounting records
• Cloud backup
• Secure document backup
• Access controls
• A clear document naming system

For important records, relying on a single laptop is a poor risk-management strategy.

What If HMRC Investigates the Company?

HMRC can check company records as part of a compliance check. The purpose is to establish whether the company has calculated and reported its tax correctly. A well-organised company should be able to answer questions such as:

Where did this £10,000 of income come from?

Why was this £4,000 expense claimed?

What does this bank transfer represent?

How was this tax adjustment calculated?

What evidence supports this deduction?

The strongest record-keeping systems make these answers easy to trace. A company does not necessarily need a huge accounting department. It needs a reliable system in which transactions can be connected to supporting evidence.

Common Tax Record-Keeping Mistakes

Mixing personal and company expenses

This makes it difficult to establish which transactions genuinely belong to the company.

Keeping only bank statements

Bank statements show money moving, but they may not explain the business purpose of every transaction.

Deleting old documents too quickly

The fact that a document is several years old does not automatically mean it can be destroyed.

Losing access to accounting software

If records are stored only within one platform, the company should understand how to retain or export the information it needs.

Failing to document unusual transactions

Large loans, asset purchases, director transactions and significant tax deductions deserve proper supporting evidence.

Treating digital copies as disposable

Electronic records are still business records. They should be backed up and protected from accidental deletion.

Frequently Asked Questions

How long must a UK company keep tax records?

For Corporation Tax and many general company accounting records, the key practical period is generally six years from the end of the relevant financial year, although some circumstances require longer retention.

Do UK companies have to keep paper copies of tax records?

No. Many records can be maintained electronically, provided they remain accurate, accessible and capable of being produced when required. VAT businesses also have specific digital record-keeping requirements under Making Tax Digital where applicable.

How long should a company keep VAT records?

Generally, VAT records must be retained for at least six years. Some businesses using specific VAT schemes can have longer requirements, including 10 years for certain OSS/MOSS records.

How long should PAYE records be kept?

HMRC currently requires employers to keep PAYE records for three years from the end of the tax year they relate to.

Do bank statements count as tax records?

Yes. Bank statements can form an important part of the company's accounting and tax evidence. However, they should normally be supported by invoices, receipts, contracts and other documents that explain the transactions.

Can I delete records after six years?

Not always. Six years is an important general benchmark, but records may need to be retained longer if, for example, they relate to assets with longer useful lives, a late Company Tax Return or an ongoing HMRC compliance check.

What happens if a company loses its tax records?

The company should attempt to recreate the records and notify its Corporation Tax office where required. Maintaining secure backups is therefore an important part of financial administration.

Does a dormant company need to keep records?

Yes. A dormant company should still maintain appropriate company and accounting records. Its record-keeping obligations do not simply disappear because it is not actively trading.

Conclusion

Good tax record keeping is one of the less visible responsibilities of running a UK company, but it becomes extremely valuable when accounts are prepared, tax returns are filed, investors request financial information or HMRC asks questions. The safest approach is to build the system before the business becomes complicated. Keep evidence of income, expenses, banking, payroll, VAT, assets, loans and other transactions. Store records securely, back them up, and make sure someone can understand the company's financial trail without having to reconstruct it from memory.

For most UK companies, six years is the central Corporation Tax record-retention benchmark, but it should not be treated as a universal rule for every document. Different taxes and circumstances can create different periods, and some records may need to be retained longer.

For global founders managing a UK company remotely, a disciplined digital record system is particularly valuable. It reduces the friction of working with accountants, makes compliance easier to manage and gives the company a dependable financial history as it grows. Ultimately, good records are not just about satisfying HMRC. They give directors a clearer picture of the business itself—and that makes better financial decisions possible.
