Accountancy fees

Fees for preparing business accounts and dealing with the tax affairs of the business are normally allowable.

Conditions

  • Fees for work on the business are allowable — preparing the business accounts, bookkeeping, payroll, and the accountancy work behind the self-employed pages of a tax return. HMRC's longstanding practice allows the normal recurring cost of preparing accounts and agreeing the tax liability on trading profits.
  • The purely personal side of a Self Assessment return — calculating personal tax, or dealing with personal investment income, capital gains and similar — is not a business cost. Where one bill covers both, only the business portion is allowable, so ask for an itemised invoice.
  • For a limited company, fees for the company's accounts and Corporation Tax return are allowable, but fees for a director's personal tax return are a personal cost — if the company pays them, it is a benefit in kind.
  • Fees for an HMRC enquiry are allowable only where it results in no adjustment, or an adjustment that does not arise from careless or deliberate error; fees tied to your own carelessness or wrongdoing are not allowable.

Common mistakes

  • Claiming the cost of personal tax advice unrelated to the business.
  • Including fees for capital or one-off transactions that may need separate treatment.

What to keep

  • Invoices from your accountant or bookkeeper.

Real-world example

A limited company pays its accountant to prepare the annual accounts and corporation tax return. These fees are a normal cost of running the company and are allowable.

Frequently asked

Are the costs of completing my Self Assessment allowable?
The element relating to the business accounts is usually allowable. A purely personal element may not be, so it can help to ask your accountant to split the fee.
Can I claim my accountant's fee for handling an HMRC enquiry?
Sometimes. If the enquiry ends with no adjustment, or an adjustment that isn't down to careless or deliberate error, the fee is usually allowable. If it uncovers mistakes caused by your own carelessness or wrongdoing, it is not.

Not sure how this applies to you?

The rules shift with your circumstances. A qualified accountant can confirm what you can claim and handle it for you.
