How this is worked out
The Rent a Room Scheme lets you earn up to £7,500 a year tax-free from furnished accommodation in your own home, or half that if you share the income with someone else. Below the threshold the exemption is automatic.
Above it you complete a tax return and either opt in, paying tax on rent above £7,500, or opt out and deduct your actual expenses instead. Opting out only lowers the bill if your expenses are more than £7,500.
The tax shown is the extra Income Tax once the taxable rent is added to your salary, so it uses your marginal band. Assumptions: England, 2026-27 rates, tax code 1257L, sole recipient of the rent, no other income.
