Self-employed tax in 2026/27

Sole traders pay income tax and Class 4 NIC on their profit (revenue minus allowable expenses). Class 2 was abolished in April 2024, but Class 4 is now 6% between £12,570 and £50,270, then 2% above. Most sole traders get a payment-on-account demand on top of their balancing payment, due in two halves on 31 January and 31 July. From 6 April 2026, MTD for Income Tax is mandatory if your qualifying self-employment and/or property income (gross turnover, not profit) exceeds £50,000, falling to £30,000 in 2027 and £20,000 in 2028.

How much tax do I pay if I'm self-employed in 2026/27?

You pay income tax on your profit using the same bands as employees (20%, 40%, 45%) after the £12,570 personal allowance. On top, Class 4 National Insurance is 6% between £12,570 and £50,270, then 2% above. Class 2 was abolished from April 2024, so most sole traders no longer pay it.

What are payments on account?

If your income tax + Class 4 NIC bill is over £1,000 and less than 80% is collected at source, HMRC asks you to make two payments on account, each 50% of the previous year's bill, due 31 January and 31 July. The Afterax self-employed calculator highlights when the payment-on-account trigger applies.

What expenses can I claim?

Anything wholly and exclusively for the business: subscriptions, equipment, business travel (not home-to-work), use-of-home, accountancy fees, mobile and broadband proportional to business use, and so on. Keep records, Making Tax Digital for Income Tax requires digital records from April 2026 for income above £50,000.

Should I pay voluntary Class 2 NIC?

Only if your profits are under the Small Profits Threshold (£7,105 for 2026/27) and you want a qualifying year for the State Pension. The voluntary rate is £3.65/week. Above the threshold, you get the qualifying year automatically without paying anything.
