Introduction
The UK property market faces significant tax reforms in 2025, impacting landlords, second homeowners, and investors. From stricter capital gains rules to green retrofit deadlines, staying compliant while maximizing profits requires careful planning. This guide breaks down the latest changes and actionable steps to protect your investments.
1. Income Tax Changes for Landlords
- Mortgage Interest Tax Relief:
- Landlords can claim 20% tax relief on mortgage interest (basic rate only).
- Higher-rate taxpayers face increased liabilities vs. pre-2020 rules.
- Furnished Holiday Lets (FHL):
- New Criteria: Properties must be available for rent 210 days/year (up from 182) and booked for 105 days.
- Scotland/Wales: Additional licensing fees for short-term lets.
Mitigation Strategy:
- Incorporate your portfolio (19% corporation tax vs. 40% income tax).
- Offset allowable expenses (maintenance, agent fees, utilities).
2. Capital Gains Tax (CGT) Updates
- Reduced Allowance: Annual tax-free allowance drops to £3,000 (from £6,000 in 2024).
- Higher Rates:
- Basic-rate taxpayers: 18% on property gains (up from 10%).
- Higher-rate taxpayers: 28% (up from 20%).
- Reporting Deadline: 60 days to report and pay CGT post-sale (penalties up to 30% for delays).
Example: Selling a second home for £150k profit in 2025 incurs £40,320 tax (28% of £150k – £3k allowance).
3. Stamp Duty Land Tax (SDLT) Adjustments
- Second Home Surcharge: Remains at 3% but now applies to properties under £40k (previously exempt).
- First-Time Buyer Relief: Extended to shared ownership properties valued up to £625k (from £500k).
- Green Discount: 1% SDLT reduction for EPC A/B-rated homes until 2027.

| Property Value | Standard Rate | Second Home Rate |
| £300k | £5,000 | £14,000 |
| £500k | £15,000 | £30,000 |
4. EPC Requirements and Penalties
- Rental Property Deadline: All UK rentals must meet EPC C by 2028 (plan upgrades by 2025 to avoid rushed costs).
- Fines: Up to £30,000 for non-compliance.
- Grants: Use the Great British Insulation Scheme to cover 50%–100% of insulation costs.
Top Upgrades for EPC C:
- Loft insulation (£300–£600).
- Double glazing (£3k–£8k).
- Heat pumps (£7k–£13k, with £7.5k grants).
5. Inheritance Tax (IHT) and Property
- Main Residence Nil-Rate Band: Stays frozen at £175k until 2028.
- Gifting Rules:
- £3,000/year tax-free gifts (can be rolled over one year).
- Gifts from income (e.g., rent) are IHT-free if regular and from surplus income.
Strategy: Transfer property into a trust or limited company to reduce IHT exposure.
Case Study: Navigating Tax as a Portfolio Landlord
James, a London landlord, restructured his 4-property portfolio in 2025:
- Incorporated: Saved £12k/year in corporation tax vs. income tax.
- EPC Upgrades: Installed insulation and heat pumps, qualifying for £5k grants.
- Gifted 1 Property: Used annual allowances to transfer a £250k flat to his daughter, avoiding IHT.
5 Tax-Saving Tips for 2025
- Use Allowances: Maximize £3k CGT and £7.5k Rent-a-Room allowances.
- Claim Green Grants: Reduce SDLT and upgrade costs via government schemes.
- Offset Mortgage Interest: Deduct 20% even if incorporated.
- Plan Disposals: Sell assets across tax years to use multiple allowances.
- Consult a Tax Advisor: Optimize ownership structures and reporting.
2025 Deadlines to Remember
- 31 January 2026: File 2024/25 self-assessment tax returns.
- 5 April 2025: Use annual CGT and gifting allowances before they reset.
- 1 April 2025: EPC requirements apply to new tenancies.
