The date of first letting is critical for tax purposes, as it impacts eligibility, timing, and clawbacks for various reliefs and deductions:
Tax Reliefs:
- Section 23 Relief and RPRIR rely on this date for claiming deductions. Properties must remain rented for a set period (4 years for RPRIR) to avoid clawbacks.
Clawback of Reliefs:
- If a property is sold or no longer qualifies as a rental property within the designated period, reliefs can be clawed back.
Pre-Letting Expenses:
- Expenses incurred within 12 months before letting can be deducted, based on the first letting date.
Capital Gains Tax:
- The date affects CGT calculations, especially for properties previously used as a principal residence.
VAT:
- For property developers, the first letting date impacts VAT adjustments under the Capital Goods Scheme.
Compliance:
- It marks the start of rental activity for tax purposes and ensures compliance with RTB registration.
