1. What is Rental Income Tax?

Rental income tax is the tax you pay on profits from renting out property in the UK. It's calculated by deducting allowable expenses and allowances from your gross rental income, then applying the appropriate tax rate.

2. How Does the Calculator Work?

The calculator uses the rental income tax formula:

Where:

• \( Rental\ Income \) — Total rent received (GBP)
• \( Allowances \) — Property allowance (£1,000) or actual expenses
• \( Expenses \) — Deductible expenses (mortgage interest, repairs, etc.)
• \( Tax\ Rate \) — Your income tax band rate (basic: 20%, higher: 40%, additional: 45%)

Explanation: The calculator first determines your taxable profit by subtracting allowances and expenses from rental income, then applies your tax rate to calculate the tax due.

3. Importance of Accurate Calculation

Details: Accurate rental income tax calculation is essential for UK self-assessment tax returns. Underpayment can lead to penalties, while overpayment means losing money unnecessarily.

4. Using the Calculator

Tips: Enter all amounts in GBP. The standard property allowance is £1,000, but you can claim actual expenses if higher. Tax rates vary by income band (20%, 40%, or 45%).
