Option 1: Personal Name — Basic Rate Taxpayer
Under Section 24, you are taxed on gross rent (£1,000), not on your real profit (£500). However, you receive a basic rate tax credit on the mortgage interest.
Tax at 22% on £1,000 = £220
Less: 22% credit on £500 mortgage interest = £110
Tax to pay: £110
Net profit after tax: £390
This is effectively the same as paying 22% on the real profit of £500. Section 24 does not create additional damage for basic rate taxpayers because the credit cancels out the distortion.
Option 2: Personal Name — Higher Rate Taxpayer
The same property. The same mortgage. But your salary or other income has pushed you into the higher rate band. Your property income now sits in 42% territory.
Tax at 42% on £1,000 = £420
Less: 22% credit on £500 mortgage interest = £110
Tax to pay: £310
Net profit after tax: £190
This is where Section 24 becomes seriously damaging. Your real profit is £500 but you take home £190. The higher rate of tax combined with Section 24 means you lose more than 60% of what you actually earned.
Option 3: Limited Company
The company is not subject to Section 24. It can deduct the full £500 of mortgage interest as a business expense.
Gross rent: £1,000
Less mortgage interest (100% deductible): £500
Taxable profit: £500
Corporation tax at 19%: £95
Net profit retained in company: £405
The company retains more than double the net profit compared to the higher rate personal name position, from the exact same property.
Key Takeaway
- At the higher rate, personal name investors keep less than 40p per £1 of real profit.
- A limited company retains £405 from the same property that leaves a higher rate taxpayer with £190.
- The Director's Loan Account allows you to access your own money tax-free.
- Structure is the first decision. Get it right before you buy.
