£1,600 in late filing penalties. Even if your tax bill is zero.
That's not a typo. HMRC's Self Assessment penalties are automatic, and they don't care whether you owe anything:
✅ £100 the day after the deadline
✅ £10 a day after 3 months — up to £900
✅ £300 or 5% at 6 months
✅ £300 or 5% again at 12 months
No warning letter. No grace period. It just runs.
And most people who get caught didn't think Self Assessment applied to them. Sole traders, landlords, company directors, anyone with dividend income, capital gains, or side income over £1,000 — if HMRC doesn't already tax it at source, you have to declare it.
There's a bigger shift happening too. Making Tax Digital started in April 2026 for income over £50,000, which turns one annual return into five submissions a year — four quarterly updates plus a final declaration.
We handle all of it. Every income source captured, every allowable expense claimed, payments on account planned, and MTD quarterly updates filed on time. You'll know your bill months early instead of finding out on the 31st of January.
Don't wait for January. The initial consultation is free — just call or email us using the details below.
