Most UK business records need to be kept for at least six years, but the exact time depends on the document and the tax it relates to. At M&J Bowers, we handle confidential waste for businesses across South and Central England every week, and “how long do we actually need to keep this?” is one of the questions we hear most.

We have pulled together the main document retention periods in the UK, covering everything from tax and company records to employee files, so you know what to hold on to, for how long, and what to do once a document has served its purpose.

Why Do Retention Periods Matter?

Retention periods exist for two reasons that pull in opposite directions.

On the one hand, HMRC, Companies House and employment law all require you to keep certain records for a set number of years so you can prove your figures if you are ever asked. On the other hand, data protection law says you should not keep personal information for longer than you need it.

Good record keeping sits in the middle: keep documents for as long as the rules require, then destroy them securely. Holding paperwork “just in case” for years after it is needed is not a safe habit. It increases your storage costs and your risk if that data is ever lost or stolen.

How Long to Keep Tax Records in the UK

Tax records are where most business owners want a clear answer, so let us start there. The right retention period depends on how your business is set up.

Self-employed people and partnerships should keep their business records for at least five years after the 31 January Self Assessment deadline for the relevant tax year. For example, if you filed your 2023 to 2024 return by 31 January 2025, you would keep those records until at least the end of January 2030.

Limited companies must keep their accounting and company records for at least six years from the end of the financial year they relate to. That covers everything from invoices and receipts to details of money the company received and spent.

VAT-registered businesses need to keep VAT records for at least six years. If you are signed up to Making Tax Digital, those records need to be kept digitally.

Employers must keep PAYE and payroll records for at least three years from the end of the tax year they relate to. In practice, we would suggest keeping them for six years, which brings payroll in line with National Minimum Wage records and the time limit for most employment claims.

There are times when you need to keep tax records for longer than the standard period. HMRC lists a few:

• A transaction covers more than one accounting period.
• You buy equipment or machinery expected to last more than six years.
• You filed your tax return late.
• HMRC has opened a compliance check into your figures.

It is also worth knowing that where HMRC suspects deliberate error or fraud, it can look back much further than six years, so accurate records protect you as much as they protect the taxman.

Document Retention Periods at a Glance

Here are the most common business documents and how long to keep each one. Treat these as safe minimums rather than hard limits:

• Self Assessment records (sole traders and partnerships): 5 years after the 31 January deadline.
• Limited company accounting records: 6 years from the end of the financial year.
• VAT records: 6 years.
• PAYE and payroll records: 3 years minimum, though 6 is safer.
• National Minimum Wage records: 6 years.
• Working Time Regulations records: 2 years.
• Statutory Maternity, Paternity and Sick Pay records: 3 years.
• Accident book and incident reports: 3 years from the last entry.
• Personnel and HR files (after an employee leaves): 6 years is common practice (5 in Scotland).
• Certificate of incorporation, statutory registers and board minutes: the life of the company.

How Long to Keep Employee and HR Records

Employee records are the area where the rules are least tidy, because different documents carry different legal roots.

Some periods are fixed in law. National Minimum Wage records must be kept for six years, a period that rose from three years in April 2021. Working Time Regulations records need only two years, and records for Statutory Maternity, Paternity and Sick Pay should be kept for three years after the end of the relevant tax year.

For general personnel files, there is no single statutory figure. Most employers keep them for around six years after someone leaves (five in Scotland), which matches the time limit for bringing most contract claims. Data protection law expects you to have a reason for holding on to that information, so a written retention schedule is the simplest way to show your reasoning.

Which Documents Should You Keep Permanently?

A small group of documents are best kept for the life of the business, and sometimes beyond it.

These include your certificate of incorporation, your memorandum and articles of association, statutory registers such as the register of members, board and shareholder meeting minutes, and key records relating to pensions, insurance and significant property or legal matters. Because these documents can be needed years or even decades later, they are the ones to file away safely rather than shred.

What Happens If You Do Not Keep Records Long Enough?

Failing to keep the right records can be costly. HMRC can charge a penalty of up to £3,000 for not keeping adequate accounting records, and company directors can, in serious cases, be disqualified.

There are quieter costs too. Without proof of your expenses, you could miss out on tax relief you were entitled to. And if HMRC opens an enquiry and you cannot produce the paperwork, it can estimate your bill for you, which rarely works in your favour.

Keeping records too long carries its own risk. Every box of old files holds personal data that you are responsible for protecting, so once a document is genuinely no longer needed, the safest thing to do is destroy it properly.

What Should You Do When the Retention Period Ends?

When a document reaches the end of its retention period, deleting a file or dropping paper in the recycling bin is not enough. Confidential business and personal information needs to be destroyed in a way that cannot be reconstructed, which is where secure shredding comes in.

When paperwork does reach the end of its life, our on-site and off-site shredding services destroy it securely and issue a Certificate of Destruction, so you have proof the job was done and can show your data was handled responsibly.

A Simple Rule to Work By

If you remember one thing, make it this: six years is a sensible default for most business and tax records, with a handful of documents kept for longer and a few, like company registers, kept for good. Build those periods into a short retention schedule, review it once a year, and you will always know what to keep and what is ready to go.
