Your 2025/26 Self Assessment
This questionnaire covers the tax year 6 April 2025 to 5 April 2026. It takes 10–25 minutes depending on how many sections apply to you.
On the next page you'll tell us which types of income, gains and reliefs applied to you during the year. You'll then only be shown the questions that are relevant — you can skip everything else.
Before you start, it helps to have to hand: P60 and/or P45, P11D, bank and building society interest statements, dividend vouchers, rental statements, pension statements, and details of any assets you sold.
You can stop at any point and come back later using the link we email you. If you're unsure about an answer, give us your best estimate and add a note — please don't leave it blank.
Please return this by 31 October 2026 so we can prepare your return in good time. Information received after 31 December 2026 may not be filed by the 31 January deadline.
