Common questions

When do I actually have to pay?

Your Self Assessment return and payment are due by 31 January after the tax year ends — 31 January 2028 for 2026/27. If your bill is over £1,000, HMRC usually also asks for two “payments on account” towards next year: half by 31 January and half by 31 July.

Why is my first bill so much bigger than my tax?

In your first year of Self Assessment the January payment covers that year's tax plus the first payment on account for the following year (half of that bill again). It catches many new sole traders out — set money aside every month so it isn't a shock.

Do I need to use Making Tax Digital?

From 6 April 2026, self-employed people and landlords with qualifying income over £50,000 must keep digital records and send HMRC quarterly updates using compatible software. The limit drops to £30,000 from 6 April 2027 and £20,000 from 6 April 2028. Qualifying income is your gross income before expenses. Our Quarterly Filing plan takes care of it.

Is a limited company better than being a sole trader?

It depends on your profit, how much you want to take out, whether you'd leave profit in the company, your clients and your appetite for admin. Dividend tax rates rose in April 2026, so at many income levels the saving is smaller than it used to be — which is exactly why it's worth a conversation before you decide.

Does this work for Scotland?

No — Scottish Income Tax bands are different. Tell us you're in Scotland and we'll work it out for you.
