What Is a Stamp Duty Land Tax Rebate?
A Stamp Duty Land Tax (SDLT) Rebate may be available if you purchased a property that was uninhabitable at the time of completion.
This applies to both main residences and investment properties, including buy-to-lets. If the property meets HMRC’s definition of “uninhabitable,” you may be entitled to claim back some or all of the SDLT originally paid.
Our Specialist Tax Advisers guide you through every step to strengthen your claim and ensure full compliance.
Key Points for Claiming SDLT on an Uninhabitable Property
Definition of ‘Uninhabitable’
To qualify, a property must lack essential living facilities or be unsafe to live in. Cosmetic issues, such as decoration or minor repairs, do not qualify.
Non-Residential or Mixed-Use SDLT Rates
If HMRC agrees the property was uninhabitable, it may be reclassified as non-residential or mixed-use, which often results in lower SDLT rates.
Claiming an SDLT Refund
If residential rates were paid in error, a refund can be claimed within 12 months of the original SDLT return.
Evidence Required
Supporting evidence may include:
-
Surveyor reports
-
Photographic evidence
-
Documentation from local authorities or utilities
Additional Dwelling Supplement (ADS) Rebate
If you paid the 3% ADS surcharge, this may also be reclaimable if the uninhabitable property replaced your main residence.
Practical Steps to Claim SDLT Relief
1. Review HMRC Guidance – Ensure your property meets uninhabitable criteria.
2. Prepare Evidence – Gather reports, photos, and documentation.
3. Submit an SDLT Reclaim – File within the statutory timeframe.
4. Seek Professional Advice – Specialists handle the process, liaise with HMRC, and strengthen your case.
