UK Freelancer Tax System 2026/27: Self Assessment Explained
UK freelancers and self-employed professionals file their taxes annually via Self Assessment with HMRC. The tax year runs from 6 April to 5 April. You must register for Self Assessment if your trading income exceeds £1,000 per year (the Trading Allowance threshold).
As a self-employed freelancer, you are responsible for paying your own Income Tax and National Insurance Contributions (NIC) — no employer deducts them at source. This means you should set aside approximately 25–30% of every invoice you receive for tax.

National Insurance for UK Freelancers (Class 4 NIC)
Self-employed freelancers pay Class 4 National Insurance on their taxable profits:
- 6% on profits between £12,570 and £50,270
- 2% on profits above £50,270
Class 2 NIC (£3.45/week) was abolished from April 2024. Class 4 NIC is calculated and paid through Self Assessment alongside income tax, in two payments on account (31 January and 31 July).
