Ready to file, or to hand over

Export a PDF for a month, a quarter or the whole tax year, with income by category, your logged costs and the tax and National Insurance worked out. The tax-year version labels your figures with the SA103S self-employment (short) box numbers, so you can copy them into your online return or pass the PDF to an accountant.

Hamster doesn’t file your return for you, and its figures are estimates, not tax advice.

The top of a sample Hamster PDF marked “Sample with made-up figures”: income by category, logged expenses, then taxable profit, Income Tax and Class 4 National Insurance for 2025–26.
