Council Tax vs. Business Rates
One of the first considerations for holiday let tax in Wales is determining whether your property is subject to council tax or business rates.
🏠 Council Tax
If your holiday let is not meeting the Welsh letting criteria, the property is treated as a domestic residence and is subject to council tax. In Wales, the current rule for self‑catering properties to be treated as non‑domestic (business rates) is that they must be:
-
Available to let commercially for at least 252 days per year, and
-
Actually let commercially for at least 182 days in the year.
If a property fails either of these conditions, it is liable for council tax rather than business rates.
Councils in Wales can charge council tax premiums on second homes or empty properties — often significantly higher than standard council tax — to reflect the housing pressures in popular tourist areas.
Business Rates
💼 Business Rates
If your holiday let meets both the 252‑day availability and 182‑day actual let thresholds, it may qualify for business rates instead of council tax. This can be more beneficial, especially for smaller properties that qualify for Small Business Rate Relief, which can reduce or eliminate business rates where the rateable value falls below certain thresholds.
Tax Treatment of Holiday Lets Post-FHL
A major shift in holiday let tax in Wales (and the rest of the UK) is the abolition of the Furnished Holiday Let (FHL) tax regime.
The FHL regime — which previously gave owners special tax treatment including certain capital allowances, favourable CGT reliefs, and pension contribution advantages — was abolished:
- From 6 April 2025 for Income Tax and Capital Gains Tax, and
- From 1 April 2025 for Corporation Tax.
This means that holiday lets are now treated in the same way as standard property income businesses for tax purposes.
Importantly, the abolition of FHL tax rules does not affect rules on council tax or business rates — those remain under devolved authority and have their own separate criteria.
Income Tax on Holiday Let Income
Owners of holiday lets in Wales must pay income tax on profits generated from their properties. Since the FHL regime ended in April 2025:
- Profits from holiday lets are taxed like normal residential rental income.
- You calculate profits by deducting allowable expenses from gross rental income.
Mortgage Interest
Mortgage interest can no longer be deducted from rental profits as a business expense. Instead, you receive a basic rate (20%) tax credit on mortgage interest costs for income tax purposes.

Capital Allowance and Other Reliefs
With the end of the FHL regime:
Capital Allowances
You can no longer claim capital allowances on furniture, fittings, or equipment purchased for the holiday let — these are treated like standard residential property.
Replacement of Domestic Items Relief
You can still claim Replacement of Domestic Items Relief when you replace worn‑out items (beds, sofas, appliances, etc.) like‑for‑like. This relief applies in place of capital allowances for new expenditure on equipment.
Inheritance Tax (IHT)
Holiday lets in Wales may still be eligible for Business Property Relief (BPR) for Inheritance Tax, but qualifying is challenging. To claim BPR, the property must be operated as a genuine business rather than passive rental. This typically requires providing substantial additional services, such as:
- Concierge or guest support services
- Regular catering
- Daily cleaning and linen changes
Passive letting without significant service provision is unlikely to satisfy the BPR conditions under HMRC’s criteria. Because IHT is complex, specialist advice from a tax adviser or accountant is strongly recommended. (HMRC guidance on BPR is available via official tax manuals and professional advisories.)
Navigating Holiday Let Tax in Wales
Owning and operating a holiday let in Wales can still be profitable, but the removal of FHL tax benefits and stricter letting thresholds mean owners must now navigate a more complex tax landscape. Tax reliefs such as CGT exemptions, capital allowances, and enhanced pension contributions no longer apply under the new system.
As always, it is highly recommended to consult a tax adviser or accountant to ensure you are complying with the latest legislation and making the most of any remaining tax reliefs available.
