The government is reintroducing interest deductibility for landlords, allowing them to deduct mortgage interest costs from rental income to lower their taxable income. This reverses the previous government's phase-out policy.
The new rules are being phased in:
- 2023/24 tax year: 60% deductible
- 2024/25 tax year: 80% deductible
- 2025/26 tax year: 100% deductible
