Every Self Assessment date, with the amount due.
For sole traders and freelancers in the UK. Pick the tax year, enter your bill, and see the return deadlines and what to pay on 31 January and 31 July.
What the rules ask
- The online return and the balancing payment are due on 31 January after the tax year ends; paper returns by 31 October (GOV.UK).
- Payments on account are each half of the previous bill, due 31 January and 31 July, unless the bill is under GBP 1,000 or more than 80% was taken at source (GOV.UK).
- A late return gets a GBP 100 penalty, even if no tax is owed.
