Estimate the additional Income Tax due from rental profit when you also have salary/other income. This models marginal bands by comparing Income Tax with vs without rental profit.
Two landlords with the same rental profit can pay different tax if one already uses up Personal Allowance or is in a higher band. This page focuses on the incremental tax due from rental profit given your other income.
Use your annual taxable pay (e.g., from your P60). Do not use take-home pay. If you have multiple sources (salary + other), combine them as other income.
Example only: other income £60,000 and rental profit £10,000 can mean the rental profit is taxed mostly at the higher rate. Enter both values to see the incremental tax attributable to the rental profit.

No. Use taxable income (e.g., your taxable pay from P60), not take-home pay.
Only if you enter it in the tax already paid field. Otherwise, the tool estimates incremental tax due from rental profit.
No, this rental tool is Income Tax only.
