4 – Paperwork, record keeping and digital reporting

Things to keep

Everyone hates filing, so…

Set up a filing system that’s easy to top up as you go along, and easy to understand if you need to look something up later.

PAYE freelancer

If you’re paid PAYE it’s a good idea to hold on to the following information:

  • pay slips
  • P60 (each tax year if you’re employed on 5th April)
  • P45 (on leaving employment, though not all freelancers get one)
  • Bank statements
  • Contracts and other agreements

Sole traders and people running companies need to keep hold of:

  • Proof of purchase for business-related expenses
  • Proof of turnover – i.e. invoices
  • Access to bank statements
  • Contracts and other agreements
  • A record of income and expenses for the business

These are a minimum, and you should keep them for at least 6 years. This is in case you are audited by the tax office, or you have a query about tax.

What are business-related expenses?

Legitimate expenses (or ‘business costs’) can be recorded so that they are ‘offset’ against tax. This means they are deducted from your turnover at the end of each tax year, making your taxable profit smaller.

Every business is potentially different, so technically every business’s costs could be different. But there are parameters:

Sole Traders can also make use of special flat rates which are called simplified expenses. These include a sliding scale of flat rates for ‘use of home’ which covers heating and lighting the place in your home where you work.

The rates are not particularly generous, but they cut down on the paperwork. [Simplified expenses are not available to Limited Companies.]

We have set up an online calculator to help you work out sole trader ‘use of home’ expenses.

Sole Traders also have a Trading Allowance of £1000, which means you don’t have to report precise expenses figures on the tax return.

This can be beneficial if you have low expenses. But you still need to keep records so that you can tell if your actual expenses are more than £1000.

We have a spreadsheet for recording turnover and business expenses, with a guide to the expense categories and a tab for recording any costs in each category:

‘Making Tax Digital for Income Tax’ (MTD for IT) – a big change for sole traders and landlords

Sole trader icon

HMRC is introducing a new system of tax reporting. Eventually nearly every sole trader (or landlord) will have to:

  • report income and business expenses every 3 months
  • use HMRC-authorised ‘cloud accounting’ software to do it

The date for reporting income tax in this way by some sole traders is April 2026 (delayed countless times for countless reasons).

We have moved all our MTD information to a special MTD section under ‘FreeStuff’.

Can PAYE freelances get tax relief on costs?

PAYE freelancer

HMRC is very suspicious of people who are paid as employed wanting to get tax back on expenses.

In their eyes it is the employer’s responsibility to reimburse their employees for out-of-pocket costs.

However there may be some scope to get tax relief in some categories of expense, as long as the employer is not reimbursing you.

You won’t be reimbursed for the whole expense – that’s not how tax relief works! But you might get a slightly lower tax bill, or a tax rebate at the end of the year.

To make things clearer, HMRC changed their systems slightly in December 2024, and you can read more about the process on this page:

Note that you need to have proof AND a justification for asking for the tax relief.
