Do I need to file a tax return if I earned nothing?

If HMRC has sent you a notice to file a tax return, you must file it, or get the notice withdrawn, even if you earned nothing. The duty comes from the notice, not from your income, and a late return brings a £100 penalty whether or not you owe tax. If HMRC has never asked you for a return and you had no taxable income, you do not need to file.

Does a notice to file apply if I had no income?

Yes. GOV.UK says simply: “You must send a return if HMRC asks you to.” That covers anyone registered for Self Assessment who has been sent a notice or a reminder for the 2025-26 tax year (6 April 2025 to 5 April 2026).

HMRC does not close records on its own. Its press release of 27 August 2024 on Self Assessment myths says HMRC will not take you out of Self Assessment automatically, will keep sending reminders and “may charge a penalty”.

Which applies to you?

Stopping self-employment part way through 2025-26 still means a return for that year, because you had income in it. See our guide to Self Assessment thresholds to check whether any income source needs reporting.

How to ask HMRC to cancel your return

Tell HMRC as soon as you know you no longer need to file. GOV.UK’s no longer need to send a tax return page says HMRC needs time to review your request before the 31 January deadline.

1. Check you have no reason to file. Look at every income source, gain and charge for the year.
2. Use the online service. Sign in to HMRC’s Self Assessment service and tell HMRC you do not need to send a return.
3. Or phone or write. If you cannot use the online service, contact the Self Assessment helpline or write to HMRC. Agents cannot use the online service and must phone or write.
4. Keep your UTR. Your Unique Taxpayer Reference stays with you if you need to file again. See how to find your UTR.
5. Wait for confirmation. HMRC will tell you whether you still need to send a return. Until it does, plan to file.

What happens if you ignore the notice?

Late filing penalties apply automatically, even when there is no tax to pay. GOV.UK’s penalties page sets them out.

With no income, the 5% charges are worked out on nil tax, so the £300 minimums apply. Twelve months late, a nil return can cost £1,600 in total.

Can a penalty be cancelled after the deadline?

Often, yes. Section 8B of the Taxes Management Act 1970 lets HMRC withdraw a notice to file, at your request or on its own initiative. The withdrawal period is 2 years from the end of the tax year, so for 2025-26 it runs to 5 April 2028. HMRC can extend it in exceptional cases.

A withdrawal notice can cancel the late filing penalty from the date it gives. Two limits apply:

• you cannot ask for withdrawal once you have filed the return for that year
• you cannot ask once HMRC has issued a determination of your tax for that year

If you have already filed late, appeal the penalty instead. HMRC accepts appeals where you have a reasonable excuse. See how to appeal an HMRC penalty.

When filing with no income makes sense

You may want to file even with nothing to tax. HMRC’s myths release lists reasons:

• Voluntary National Insurance. Self-employed people with low or no profits can pay voluntary Class 2 contributions, £3.65 a week for 2026-27, to protect State Pension qualifying years.
• Claiming a refund. You may be owed tax back, for example on pension contributions or tax deducted from income.
• Claiming reliefs. Losses from a trade can be recorded to set against future profits.
• Proving self-employment. Some benefit and mortgage applications ask for a filed return.

A “nil return” is just a normal return with no income entered. File it online by 31 January 2027.

What to do now

1. Check your personal tax account for any 2025-26 return HMRC is expecting.
2. If you have no reason to file, ask HMRC to cancel it now, not in late January.
3. If you are unsure, file a nil return before 31 January 2027. It costs nothing and removes the penalty risk.
4. If you need to start filing again later, register again by 5 October after that tax year ends.

Frequently asked questions

Do I have to file a tax return if I had no income?

Only if HMRC has sent you a notice to file. If it has, file by 31 January 2027 or ask HMRC to withdraw the notice.

Will I get a penalty for not filing a nil return?

Yes, if HMRC issued a notice and you neither filed nor had it withdrawn. The first penalty is £100, even with no tax due.

How do I tell HMRC I no longer need to file?

Use HMRC’s online Self Assessment service, phone the helpline or write. Agents must phone or write.

Can HMRC cancel a late filing penalty if I had no income?

HMRC can withdraw the notice to file within 2 years of the end of the tax year, which can cancel the penalty, provided you have not filed the return.

Do I need to file if I stopped being self-employed?

Yes, for the tax year in which you stopped, because you had trading income in that year. After that, tell HMRC so it can close your record.
