Financial Management
Rental Income Tax
Rental profit is taxed as income. See our property tax guide for full details.
| Income | Expenses | Profit | Tax (40% rate) |
|---|---|---|---|
| £12,000 | £4,000 | £8,000 | £3,200 |
Plus mortgage interest tax credit (20% of interest, not deducted from income):
| Mortgage Interest | Tax Credit (20%) | Net Tax Relief |
|---|---|---|
| £6,000 | £1,200 | Basic rate: full relief; Higher rate: only 20% |
Allowable Expenses
| Deductible | Not Deductible |
|---|---|
| Letting agent fees | Mortgage capital repayments |
| Insurance (landlord, buildings) | Property purchase costs |
| Maintenance and repairs | Your own time/labour |
| Ground rent and service charges | Capital improvements (but CGT offset) |
| Accountancy fees | Personal use portions |

Annual Financial Summary
| Item | Annual Amount |
|---|---|
| Rental income | £12,000 |
| Less: Mortgage interest | -£6,000 |
| Less: Other expenses | -£3,000 |
| Net cash flow | £3,000 |
| Tax on profit (£8,000 at 40%) | -£3,200 |
| Plus mortgage interest credit | +£1,200 |
| After-tax cash flow | £1,000 |
This example shows why the mortgage interest restriction has significantly reduced returns for higher rate taxpayer landlords.

|---|---|
| Void periods (empty property) | Price competitively, maintain well, tenant retention |
| Late rent payments | Screen tenants well, clear payment terms, prompt follow-up |
| Maintenance issues | Respond quickly, use reliable contractors, regular inspections |

Tax-Efficient Structuring
Limited Company
Some landlords hold property through a limited company:
| Feature | Personal Ownership | Limited Company |
|---|---|---|
| Mortgage interest | Basic rate tax credit only | Fully deductible |
| Tax rate on profits | Up to 45% income tax | 25% corporation tax |
| Extracting profits | N/A | Taxed again (dividend/salary) |
| CGT on sale | 18/24% | Corporation tax, then extraction costs |
| Mortgage availability | Wider, lower rates | More limited, slightly higher rates |
Consider a limited company if: buying new properties, higher rate taxpayer, planning to retain profits for further investment. Seek professional advice before restructuring.
