What happens if I miss an MTD quarterly update?
Missing a quarterly update deadline isn’t ideal, but it isn’t the cliff-edge it might sound like. HMRC uses a penalty points system designed to be lenient about the occasional slip while still discouraging a pattern of lateness.
How the points system works
Each time you miss a deadline, you get one penalty point. Points expire after a period of consistent on-time filing. A financial penalty only kicks in once you reach a points threshold (the exact threshold depends on how often you’re required to file), a single missed update on its own doesn’t trigger a fine.
The first-year soft landing
HMRC has said it will take a lighter-touch approach to penalties in the first year of the mandate, recognising that taxpayers, agents, and software are all adjusting at the same time. That’s a reason to fix a mistake calmly rather than panic, not a reason to ignore deadlines altogether.
What to actually do if you’re late
- Submit it anyway, as soon as you can. A late update is still better than no update, and stops the gap from growing.
- Check what caused it. If it was a software issue, a change of address, or lost access to your Government Gateway account, that context can matter if you ever need to explain a pattern of lateness.
- Get ahead of the next one. Use the deadline calculator to add every quarter’s due date to your calendar in one go, so it isn’t a surprise next time.
The bigger picture
A quarterly update being late doesn’t change how much tax you owe: it’s a compliance matter, not a tax bill. See what a quarterly update actually is if that distinction isn’t clear yet.
