Frequently Asked Questions

You need to file if you're self-employed, a company director, earn over £150,000, have rental income, have significant investment income, or have capital gains to report. If you're unsure, we can quickly check if you need to file.

The deadline for online self assessment tax returns is 31 January following the end of the tax year (5 April). For paper returns, the deadline is 31 October. We recommend filing as early as possible to avoid the last-minute rush.

We'll send you a simple checklist, but generally you'll need your P60/P45, details of any self-employment income and expenses, rental income records, bank interest statements, dividend vouchers, and details of any asset sales.
