What Is the £45,000 Tax-Saving Trick Revealed?
It’s not a hidden loophole or secret scheme—it’s a collection of HMRC-approved strategies that, when used together, can significantly reduce the amount of income tax, capital gains tax, and National Insurance you pay. Smart Brits are combining pensions, ISAs, salary sacrifice arrangements, and other tools to keep more of their earnings and plan better for the future.
Let’s explore how each of these strategies works and how they can be applied in 2025.
1. Maximise Your Pension Contributions
Pension contributions are one of the most powerful tax-saving tools available in the UK. In 2025, you can contribute up to £60,000 per year into your pension (depending on income and previous allowances).
- Higher-rate taxpayers (40%) get £16,000 back in tax relief for every £40,000 contributed.
- Additional-rate taxpayers (45%) can save even more.
- Contributions via salary sacrifice can increase savings further by lowering both income tax and NI.
Tip: You may also carry forward unused allowances from the past three years if you qualify.
2. Leverage Salary Sacrifice Schemes
Salary sacrifice allows you to exchange part of your salary for non-cash benefits, reducing your gross income—and therefore your tax and National Insurance bill.
Popular options include:
- Additional pension contributions
- Childcare vouchers
- Cycle-to-work schemes
- Electric car leases
Example: Sacrificing £5,000 of your salary into your pension can save you over £2,000 in combined taxes while boosting your retirement fund.
3. Max Out Your ISA Allowance
In 2025, you can invest up to £20,000 per year in an ISA with zero tax on income, dividends, or capital gains.
Types of ISAs:
- Cash ISAs – for savings with fixed interest
- Stocks & Shares ISAs – for long-term investment
- Lifetime ISAs – ideal for first-time buyers or retirement saving
For couples: You can shelter £40,000 annually across two ISAs.
Pro Tip: Stocks & Shares ISAs are usually more rewarding over 5+ years than Cash ISAs, especially in a low-interest environment.
4. Gift Aid Charitable Donations
When you donate to a UK-registered charity and select Gift Aid, the charity receives an extra 25% from the government. If you’re a higher-rate (40%) or additional-rate (45%) taxpayer, you can also claim extra tax relief.
Example:
- Donate £1,000 → charity receives £1,250
- You can reclaim £250–£312.50 depending on your tax rate via Self Assessment
This is a great way to support good causes and reduce your tax at the same time.
5. Use Capital Gains Tax (CGT) Allowance Wisely
In 2025, the annual CGT exemption is just £3,000, down from previous years. To make the most of it:
- Sell and rebuy assets within an ISA to shield future gains (known as Bed & ISA)
- Transfer assets to a spouse to use both allowances
- Crystallise gains annually to avoid large tax bills later
Example: A couple with £6,000 in capital gains can sell strategically and avoid any CGT through careful planning.
6. Marriage Allowance Transfer
If one partner earns below the personal allowance threshold (£12,570) and the other is a basic-rate taxpayer, you can transfer £1,260 of unused personal allowance.
This can save up to £252 per year, and claims can be backdated up to 4 years, totaling over £1,000 in refunds.
7. Tax-Efficient Investing (EIS, SEIS & VCTs)
For experienced or high-net-worth investors, government-backed schemes like:
- Enterprise Investment Scheme (EIS)
- Seed Enterprise Investment Scheme (SEIS)
- Venture Capital Trusts (VCTs)
…offer significant tax advantages:
- Income tax relief of 30% (EIS/VCT) or 50% (SEIS)
- Capital Gains Tax relief or deferral
- Loss relief on failed investments
Note: These come with higher risk and should only be used under financial advice.
