Generally speaking they run from April 6th to April 5th, with the payment being due the following January

Green Row
The tax return and payment due on the 31st January 2026, is for any sales you made between April 6th 2024 and April 5th 2025.
So, in reality, this year (24/25) has already closed in regard to sales made, it's just that payment is due this coming January.
Blue Row
This is known as the 'current tax period' in regard to recording sales made. This started on April 6th 2025 and will end on April 5th 2026. Your tax return and any payments will be due on January 31st 2027
So your actions at the moment should be;
1 Getting your tax numbers together for January, so you can either pay any tax due or show HMRC you don't owe any tax.
2 Keeping records of your sales between April 6th 2025 and will end on April 5th 2026.
We advise you do this on an ongoing basis.
