Who needs to file a Self Assessment tax return?
You'll usually need to file a return if, in the last tax year (6 April to 5 April), you:
- were self-employed and earned more than £1,000 before expenses
- were a partner in a business partnership
- had income from renting out property
- had untaxed income, such as tips, commission, foreign income or significant savings and investment income
- need to pay the High Income Child Benefit Charge
- sold assets and made a gain above the Capital Gains Tax allowance
If you're not sure, an accountant can check your situation in a few minutes and tell you whether you need to register.

Key Self Assessment deadlines
- 5 October: register for Self Assessment if you need to file for the first time
- 31 October: paper tax returns are due
- 31 January: online tax returns are due, along with any tax you owe and your first payment on account
- 31 July: your second payment on account is due
Miss the 31 January deadline and HMRC charges an automatic £100 penalty, even if you don't owe any tax. More penalties and interest follow the longer it's late.
What an accountant does for you
A good accountant does far more than type numbers into HMRC's website. They'll make sure you claim the expenses and allowances you're entitled to, check whether you can reduce your payments on account, spot anything HMRC is likely to question and file everything on time. Many will also remind you what's coming up, so January is never a last-minute scramble.
If you're behind on returns or have had a letter from HMRC, an accountant can sort out late returns and deal with HMRC for you.
Self Assessment questions
How much does an accountant charge for a Self Assessment tax return?
As a rough guide, a straightforward return costs from around £150 to £400. It costs more if you have several income sources, rental properties, capital gains or a lot of bookkeeping to tidy up first. Ask for a fixed fee before you commit.
Can an accountant help if my tax return is late?
Yes. Accountants deal with late and missing returns all the time. They'll get your returns filed, work out what you owe and, where there's a reasonable excuse, can help you appeal penalties.
What do I need to give my accountant?
Usually your UTR (Unique Taxpayer Reference), your National Insurance number, records of your income and expenses, P60s or P45s from any jobs, and details of any rental income, pensions, savings interest or dividends.
