Property Income Tax Calculator
Use this property income tax calculator to estimate the tax due on UK residential rental income. Enter your rent, allowable expenses, mortgage interest, employment income, self-employment profit and PAYE tax already deducted.
The calculator treats residential mortgage interest and finance costs as a basic rate tax reducer, not as a direct deduction from rental income. It is designed for individuals and gives an estimate only.
For most individual residential landlords, mortgage interest is not deducted from rental income when calculating taxable property profit. Instead, it normally gives a 20% tax reducer, restricted by the finance costs, property profit and taxable income position.

How the calculator works
Mortgage interest is treated differently from other expenses
For individual landlords with residential property, most finance costs are not deducted from rental income as a normal expense. The calculator therefore deducts allowable property expenses first, but keeps mortgage interest separate.
It then estimates a 20% basic rate tax reduction based on the lower of mortgage interest, property profit and taxable income above the Personal Allowance.
This calculator does not include
- Property losses brought forward.
- Joint ownership splits.
- Furnished holiday letting rules.
- Limited company property income.
- Capital Gains Tax on property sales.
- Student loan repayments.
- High Income Child Benefit Charge.
- Payments on account and HMRC interest.
When to ask for help
Ask us to check your landlord tax position before filing
Rental income can become complex where there are mortgage costs, joint owners, repairs, losses, capital improvements, overseas landlords or undeclared earlier-year income.
You have mortgage interest
Finance costs normally give a tax reducer rather than a deduction, and the relief can be restricted.
You have joint property
Ownership shares, Form 17, beneficial interests and spouse allocations may need review.
You made repairs or improvements
Repairs may be revenue expenses, while improvements may be capital and relevant for CGT.
You have property losses
Losses usually need to be carried forward within the property business and tracked correctly.
You are a non-resident landlord
NRL scheme, UK Self Assessment and UK rental reporting may need to be dealt with separately.
You missed earlier years
Undeclared rental income may need a Let Property Campaign disclosure rather than a normal return.

Common questions
Property Income Tax Calculator FAQs
Can I deduct mortgage interest from rental income?
For most individual residential landlords, mortgage interest is not deducted as a normal expense. It normally gives a basic rate tax reducer instead.
What expenses can I include?
Common allowable expenses include letting agent fees, repairs, insurance, service charges, accountancy fees and other costs incurred wholly and exclusively for the rental business. Mortgage interest should be entered separately.
Does this calculator include property losses?
No. It is a simplified annual estimate. Property losses brought forward and carried forward should be reviewed separately before filing a tax return.
Does this calculate Capital Gains Tax?
No. This calculator estimates Income Tax on rental profits. Capital Gains Tax on a property sale uses different rules, reliefs, rates and reporting deadlines.
Can this be used for a limited company property?
No. This calculator is designed for individual landlords. Limited companies are taxed under Corporation Tax rules and usually treat finance costs differently.
