How much can I earn before paying tax when self-employed?

How much can I earn before paying tax when self-employed? In 2026-27 you pay no Income Tax or Class 4 National Insurance on self-employed profit up to £12,570, if you have no other income. Over £1,000 of takings, you must still register and file a tax return. If you have no other income, £12,570 of profit, which is your personal allowance. Class 4 National Insurance also starts above £12,570 of profit. Yes, if your gross self-employed income is over £1,000. If you are not already registered, you must register for Self Assessment by 5 October after the end of the tax year, and you must send a return even if no tax is due. On profit: what customers pay you minus allowable business costs. The £1,000 test for telling HMRC is different, because it looks at your income before costs.
