I have not filed my UK tax return
What to do if your UK Self Assessment tax return is late, missing, or unfiled. How to stop fines and appeal penalties.
Short answer: Don't panic if your UK tax return is late. Late returns trigger an immediate £100 fine, plus daily penalties up to £900+ and interest. Matthew brings your unfiled returns up to date fast, files them directly with HMRC, and appeals unfair late penalties.
Key points
- An automatic £100 fine applies the moment the 31 January deadline passes.
- After 3 months, daily £10 penalties start building up to an extra £900.
- Filing your return immediately stops further penalties and daily interest.
- Matthew can submit formal penalty appeals where you had a reasonable excuse.
- Authorising Matthew under Form 64-8 stops stressful HMRC letters and phone calls.
Stop mounting penalties immediately
If you have missed one or more tax years, the worst thing you can do is wait for HMRC to take enforcement action.
Penalties increase automatically over time. By submitting your outstanding returns immediately, you freeze the penalty clock and prevent further daily interest.
