AI summary
The government is reintroducing interest deductibility for rental property mortgage costs, reversing the previous phase-out policy. Landlords can now claim a percentage of their interest expenses against their rental income.
The phased reintroduction is as follows:
- 2023/24 tax year: 60% deductible
- 2024/25 tax year: 80% deductible
- 2025/26 tax year: 100% deductible
Additionally, the bright-line test has been shortened to two years. Landlords should consult a tax accountant to navigate these changes and ensure compliance.
