FAQ
Which tax year does this cover?
The tool covers the 2024/25 tax year (6 April 2024 to 5 April 2025), due by 31 January 2026. I also offer a 2025/26 update as a gig extra. All figures use current HMRC rates including the personal allowance and National Insurance thresholds.
. Do I need an accountant to use this?
No. This toolkit is built for people who want to file their own HMRC Self Assessment return without paying accountant fees of £200–£500. You enter your figures, the calculator does the maths, and the guide shows you exactly what to submit.
What expenses can I claim on Self Assessment?
Sole traders and freelancers can claim office costs, travel, equipment, phone bills, marketing, and professional subscriptions. My expenses maximiser worksheet covers every HMRC-allowable deduction so you pay the least tax legally possible.
