How long do you need to keep tax records for in the UK? What’s the importance of record keeping? And more importantly, how should self-employed people go about keeping business records in the first place?

Accurate record keeping is really important for self-employed business owners.

Not only do accurate records mean you’ll pay the right amount of tax, they can also keep you out of trouble in the event of an HMRC tax investigation.

What’s more, business owners are required to keep tax records for a certain number of years.

How long do you need to keep tax records?

Self-employed Self Assessment taxpayers need to keep their business records for at least five years after the 31 January deadline of the relevant tax year.

So if you filed your 2022-23 tax returns ready for the relevant deadline on 31 January 2024, you’ll need to keep your records until 31 January 2029.

If you run a limited company and need to file a company tax return, there are more rules and regulations.

For example, you’ll need to keep your accounting records for longer – six years from the end of the last company year they relate to.

There are some situations when limited companies need to keep records for longer, such as:

Record keeping: step-by-step for the self-employed

Businesses need to keep records of their income and expenses, but the rules are different depending on your legal structure.

Record keeping for sole traders and partnerships

1. Choose an accounting method

There are two accounting methods the self-employed can use – traditional and cash basis accounting.

Using traditional accounting:

2. What business records to keep

HMRC lists the records that sole traders need to keep. They include:

And if you use traditional accounting there’s more records you need to keep, like what you’re owed but haven’t received yet, as well as how much you’ve invested in the business over the year.

3. How to keep business records

There’s lots of information you need to keep – HMRC says you should also keep proof alongside your records, including all:

So it’s really important to have an effective filing system for all your business records. This should make everything easier when it comes to the tax-year end.

There’s accounting and invoice software available that can automate some of these tasks and keep your records in one place. For example, some apps let you scan and upload your receipts.

If you do end up losing your records, you need to tell HMRC whether you’re using estimated figures or provisional figures when filling in your tax return. Provisional figures are best estimates while you wait for the actual figures.

Here are some tips for record keeping:

Record keeping for limited companies

1. Company records

While limited company directors will need to file a Self Assessment tax return, they’ll have more responsibilities than sole traders when it comes to record keeping.

That’s because the limited company legal structure is more complex, as it’s a separate entity.

This means you need to keep records of the company itself (not just financial records).

2. Accounting records

If you don’t keep accounting records, you can be fined £3,000 and disqualified as a company director, so it’s important you do this correctly.

As well as information about the company, you need to keep financial and accounting records.

If your records are lost, you need to try to recreate them. Tell your corporation tax office straight away and mention it in your company tax return.

3. How to keep limited company records

With the breadth of business records that limited companies need to keep, it’s important to have an effective system in place.

Hiring professionals like accountants and bookkeepers can be useful – but make sure you do your research and only work with people who have a good reputation.

While professionals are often expensive, they free up your time so you can focus on running your business. Plus, they can advise on record-keeping and your overall tax liabilities.

Accounting and invoice software can also make record keeping a lot easier.
