Tax for the Self-Employed in 2026/27
If you are self-employed in the UK, you pay Income Tax on your profits above the £12,570 Personal Allowance at the same rates as employees (20%, 40%, 45%). However, instead of employee National Insurance, you pay Class 4 NI contributions at 6% on profits between £12,570 and £50,270, and 2% above that.
Mandatory Class 2 NI contributions were abolished from April 2024. You must register for Self Assessment with HMRC and file a tax return each year by 31 January. Your tax bill is due in two payments on account — 31 January and 31 July.

Frequently Asked Questions
How much tax do self-employed people pay? ▼
Self-employed people pay Income Tax at 20%, 40% or 45% on profits above £12,570, plus Class 4 NI at 6% (up to £50,270) and 2% above that. The exact amount depends on your profit level.
Do I pay Class 2 NI anymore? ▼
No. Mandatory Class 2 NI was abolished from April 2024. Those earning between £6,725 and £12,570 still receive NI credits automatically to protect their state pension entitlement.
When is my Self Assessment tax return due? ▼
The Self Assessment deadline for online returns is 31 January each year. Your tax is paid in two payments on account — 31 January and 31 July — plus a balancing payment by the following 31 January.
Can I reduce my tax bill through pension contributions? ▼
Yes. Pension contributions made to a personal pension reduce your taxable profits, lowering your Income Tax and Class 4 NI bill. This is one of the most tax-efficient ways for self-employed people to save.
