  • Secondly, add allowable expenses and put the amount under self-assessment tax return.

You do not need to send proof of expenses along with your tax return. They are to be kept if asked by HMRC.

Final thoughts

Accuracy is the focus while calculating deductible expenses. Any mistake means you are claiming less than you are entitled to, and your tax refund claim will be less. Claiming more implies a risk of fines from HMRC.
