When do self-employed cleaners pay tax?

Any tax owed for a tax year is due by 31 January following that year's end. If payments on account apply, you'll also pay instalments each 31 January and 31 July toward the following year's bill.

What happens if I miss the deadline?

A late return brings an automatic £100 penalty even if you owe no tax, with further penalties as the delay grows, plus interest on late payments. If something's gone wrong, file and contact HMRC as soon as possible; penalties escalate with time.

How much tax will I actually pay?

Tax is charged on profit above your £12,570 Personal Allowance, at 20% within the basic rate band, plus Class 4 National Insurance on profits above its threshold. A part-time cleaning profit of £8,000 with no other income generates no Income Tax at all; the same profit alongside a full-time job is taxed from the first pound.

What are payments on account?

Advance instalments toward your next tax bill, triggered once your bill exceeds £1,000. You pay half of last year's bill on 31 January and half on 31 July, credited against whatever you actually owe next year. They surprise almost everyone in year two, which is why this article exists.

Do I need to keep every receipt?

Keep a record of every business expense, and evidence (receipts or bank records) to support it, for at least five years after the filing deadline. Photographed receipts are fine. If you can't evidence a claim, you risk losing it if HMRC ever asks.

Can I complete my own Self Assessment?

Yes, and most solo cleaners with organised records do. The online form calculates everything for you and shows the total before you submit. Consider an accountant when your situation stops being simple or when the peace of mind is worth the fee.

Do I still file a return if I earned very little?

Once you're registered, yes, every year unless HMRC tells you otherwise, even if you owe nothing. If you've genuinely stopped trading, tell HMRC so they can close the requirement properly.
