What Is the £45,000 Tax-Saving Trick Revealed?
This term has become a buzzword in UK financial circles—but it’s not about a loophole or secret tax exemption. Instead, it’s about understanding and combining the tools HMRC already provides for reducing your taxable income. Let’s break down how people can realistically save up to—or even more than—£45,000 in taxes and grow their wealth without any grey-area schemes.
1. Maximise Your Pension Contributions
One of the most powerful tax planning tools is the pension system. In 2025/26, you can contribute up to £60,000 annually into your pension and receive tax relief at your marginal rate.
If you’re a higher-rate taxpayer (40%), contributing £40,000 can save you £16,000 in income tax. If you’re an additional rate taxpayer (45%), the savings could be even higher.
- Contributions can be made personally or via your employer (through salary sacrifice).
- You may also carry forward unused allowance from the past three years.
Tip: Check your adjusted income, as high earners may have a reduced pension allowance.
2. Leverage Salary Sacrifice Schemes
With salary sacrifice, you reduce your gross pay in exchange for benefits like:
- Additional pension contributions
- Childcare vouchers
- Cycle-to-work schemes
- Electric car leases
This not only reduces your income tax and National Insurance but can also help you stay below key tax thresholds, such as the £100,000 level where your personal allowance begins to taper off.
Example: Sacrificing £5,000 towards pension contributions could save over £2,000 in combined tax and NI.
3. Max Out Your ISA Allowance
The £20,000 per person ISA limit lets you save or invest without paying any income tax, dividend tax, or capital gains tax on your returns.
- Choose from Cash ISAs, Stocks & Shares ISAs, or Lifetime ISAs (for first-time buyers or retirement).
- A couple can shelter £40,000 tax-free annually.
Pro Tip: If you’re investing for the long-term (5+ years), a Stocks & Shares ISA can generate better returns than a cash ISA, especially in a low-interest environment.
4. Gift Aid Charitable Donations
When you donate to UK-registered charities and tick the Gift Aid box, the charity can claim 25% extra from the government, and you may claim additional relief if you’re a higher or additional-rate taxpayer.
- Donate £1,000 → The charity receives £1,250
- You can claim back £250 (higher rate) or £312.50 (additional rate) via Self Assessment
This not only supports worthy causes but also lowers your tax bill.
5. Use Capital Gains Tax (CGT) Allowance Wisely
The CGT annual exemption in 2025/26 is just £3,000, down from previous years. If you own shares, crypto, second properties, or other investments, consider:
- Crystallizing gains to use your allowance each year
- Bed & ISA: Sell and immediately buy back within an ISA to shelter future growth
- Transfer assets to a spouse or civil partner to double the allowance
Example: A couple selling shares with £6,000 in gains can avoid any CGT by using their allowances strategically.
6. Marriage Allowance Transfer
If one spouse earns below the personal allowance (£12,570) and the other is a basic-rate taxpayer, the lower earner can transfer £1,260 of their allowance—cutting the other’s tax bill by up to £252 per year.
You can backdate this claim for up to four years, potentially claiming over £1,000 in total.
7. Tax-Efficient Investing (EIS, SEIS & VCTs)
For experienced investors with higher risk tolerance, Enterprise Investment Scheme (EIS), Seed Enterprise Investment Scheme (SEIS), and Venture Capital Trusts (VCTs) offer:
- Income tax relief (30% for EIS/VCT, 50% for SEIS)
- CGT deferral or exemption
- Loss relief on failed investments
These are advanced strategies and should only be used after taking professional financial advice.
