Tax Calculation Summary

Understanding Buy to Let Taxation in the UK

If you own property that you rent out in the UK, the income you earn is taxable. HMRC requires landlords to declare rental income and pay tax on the profits after subtracting allowable expenses. The tax you pay depends on your total income, which includes earnings, pensions, and rental profits.

What Counts as Taxable Rental Income?

Gross rental income includes rent payments and any additional charges tenants pay (like maintenance or cleaning). Your net income is calculated after deducting allowable expenses like:

  • Letting agent fees
  • Maintenance and repairs
  • Property insurance
  • Council tax and utility bills (if paid by you)

Mortgage Interest Relief

As of current rules, you can't deduct full mortgage interest from rental income. Instead, you get a 20% tax credit on the mortgage interest paid, known as Section 24 relief.

Tax Bands and Rates

  • Basic rate: 20% on income between £12,571 to £50,270

  • Additional rate: 45% over £125,140
