Time completions to spread SDLT payments across financial years if managing multiple purchases.

📈 Capital Gains Tax Planning for Property
Property CGT Rates 2024/25
- Basic Rate Taxpayers: 18% on property gains
- Higher/Additional Rate: 28% on property gains
- Annual Allowance: £3,000 tax-free gains
- Company Ownership: 19-25% Corporation Tax on gains
CGT Minimization Strategies
1. Use Annual Allowances
Sell properties across multiple tax years to utilize £3,000 allowance repeatedly. Joint ownership with spouse doubles this to £6,000.
2. Consider Company Structure
For higher rate taxpayers, company ownership can reduce CGT from 28% to 19-25% Corporation Tax.
3. Private Residence Relief
If you lived in the property, you may qualify for relief that can eliminate CGT entirely for those periods.
4. Lettings Relief
If you let a property that was once your main home, you may qualify for up to £40,000 lettings relief.

🎯 Practical Tax Optimization Strategies
1. Income Splitting Through Joint Ownership
How It Works: Own property jointly with spouse/partner to split rental income
Tax Benefit: Utilize both personal allowances (2 × £12,570 = £25,140 tax-free)
Example Saving: £20,000 rental income split 50/50 = £10,000 each, potentially saving £2,000-£4,000 annually
Requirements: Genuine beneficial ownership, not just for tax avoidance
2. Mortgage Interest Strategy
Personal Ownership: Only 20% tax relief on mortgage interest (from 2020/21)
Company Ownership: Full deduction of mortgage interest against rental income
Example: £10,000 annual interest = £2,000 tax credit (personal) vs £1,900-£2,500 Corporation Tax saving (company)
Impact: Company structure becomes more attractive with higher mortgage interest
3. Capital Gains Tax Planning
Annual Allowance: Use £3,000 CGT allowance each year (£6,000 for couples)
Timing: Spread property sales across tax years to maximize allowances
Company vs Personal: 19-25% Corporation Tax vs 18-28% personal CGT
Relief Claims: Consider lettings relief, private residence relief, or business asset disposal relief
4. Expense Optimization
Keep Records: Document all property-related expenses for tax relief
Pre-letting Expenses: Claim renovation costs as allowable expenses
Mileage Claims: 45p per mile for property visits
Professional Fees: Accountancy, legal, and survey costs are deductible
