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

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 |

This example shows why the mortgage interest restriction has significantly reduced returns for higher rate taxpayer landlords.

Tax-Efficient Structuring
Limited Company
Some landlords hold property through a limited company:

Consider a limited company if: buying new properties, higher rate taxpayer, planning to retain profits for further investment. Seek professional advice before restructuring.
