But there’s a catch: you need to act fast, prepare early, and understand how to position yourself.
This article explains the tax strategy in simple terms, identifies who can benefit the most, offers step-by-step guidance, and shows how to use existing rules to save thousands right now—even if the proposal doesn’t come into law.

The proposed increase in the UK’s Personal Allowance to £45,000 could unlock life-changing tax savings, particularly for middle-income earners. While it isn’t law yet, taking proactive steps now helps you prepare for the best-case scenario while benefiting from tax-efficient strategies under the current system.
From pension top-ups to ISAs, salary sacrifice, and marriage allowances, there are multiple ways to reduce your taxable income today. Think of this as future-proofing your finances.
What Is the 2025 Tax Strategy All About?
At the heart of this strategy is a proposed increase in the Personal Allowance – the amount of income you can earn each year before paying any income tax. Currently set at £12,570, the idea is to boost it to as high as £45,000 in 2025 to help households cope with rising living costs and improve spending power across the economy.
This would be one of the biggest tax breaks in UK history for middle-income earners. For someone earning £45,000, this could mean avoiding tax on over £32,000 of income, which would usually be taxed at the basic rate of 20%. That equates to an annual tax saving of approximately £6,486, not including any impact from NI or other reliefs.
If such an allowance were sustained over multiple tax years, the cumulative savings could amount to tens of thousands of pounds, especially when paired with smart tax planning. However, there’s a big caveat…
Important: This proposed change is still speculative. It has been discussed in political circles and media reports, but is not yet law, and may change depending on the next fiscal budget or general election.
Why Acting Now Matters
Even though the change hasn’t been enacted, preparing now gives you two key advantages:
- You’re ready to act immediately if it’s introduced in a future budget.
- Most of the tactics involved are already beneficial under current rules, so you save money regardless.
Waiting for legislation to be passed could leave you scrambling at the last minute, missing out on opportunities to align your income, pension, and investments in a tax-efficient way. The sooner you start planning, the more control you have over how much you pay — or don’t pay — in taxes.
Who Benefits Most From This Strategy?
While this change would benefit nearly all UK taxpayers, certain groups stand to gain the most:
- Employees and freelancers earning £45,000 or less, as their entire income would be tax-free
- Dual-income households, especially where one partner earns under the threshold
- Self-employed individuals and small business owners, who can adjust income timing
- Retirees drawing income from pensions and savings, who may shift withdrawals to stay within a tax-free bracket
- Young professionals building long-term wealth, who can start planning early and compound tax savings
If you’re in one of these groups, the time to optimize your tax strategy is now, not when the rules change.
How to Save Tax in 2025
1. Understand Your Taxable Income
Start by calculating all sources of income:
- Employment or salary income
- Self-employment profits
- Investment income (dividends, interest)
- Pension income or state benefits
- Rental income from properties
Use HMRC’s calculator here: Check your income tax
Knowing your total taxable income helps you understand where you sit in the tax bands and how much of your income could potentially be shielded if the allowance increases.
2. Boost Your Pension Contributions
One of the best ways to reduce your taxable income is by contributing more to your pension. Contributions are eligible for tax relief, meaning:
- If you’re a basic rate taxpayer, HMRC tops up your contribution by 20%
- Higher-rate taxpayers can claim back an additional 20% via self-assessment
By contributing now, you get immediate tax benefits and, if the tax-free threshold rises, you can draw income later tax-free.
2025 rules allow up to £60,000 in annual contributions (subject to earnings). More details
3. Maximize Your ISA Allowances
ISAs (Individual Savings Accounts) are completely tax-free on interest, dividends, and capital gains. You can contribute:
- £20,000 per person, per tax year
- To any mix of Cash ISAs, Stocks & Shares ISAs, Innovative Finance ISAs, or Lifetime ISAs (for under 40s)
ISAs are ideal for building long-term wealth without future tax liability. Explore your options
4. Leverage Salary Sacrifice Schemes
Salary sacrifice lets you reduce your gross pay in exchange for certain benefits, which lowers your taxable income. Examples include:
- Extra pension contributions
- Electric car leasing
- Cycle-to-work schemes
- Childcare vouchers (for older agreements)
This can save you both income tax and National Insurance. It’s worth checking with your employer what schemes are available.
5. Use the Marriage Allowance
If you’re married or in a civil partnership, and one person earns below the Personal Allowance, you can transfer up to £1,260 of unused allowance to the higher earner.
This can reduce your household tax bill by up to £252 per year, and it’s quick and easy to apply. Check eligibility and apply
6. Make Charitable Donations with Gift Aid
Donating to charity via Gift Aid gives tax relief:
- For every £1 you donate, the charity gets £1.25
- Higher rate taxpayers can claim the additional 25p as tax relief
This reduces your taxable income and supports good causes. Learn how
7. Defer Income or Bonuses Strategically
If you’re expecting a large bonus or dividend in early 2025, speak to your employer or accountant about deferring it to the new tax year.
If the £45,000 threshold becomes law, this could allow you to receive more income tax-free, rather than losing a portion to tax in the current regime.
This strategy works especially well for self-employed people who control when income is withdrawn.
8. Use Capital Gains Tax (CGT) Exemptions Wisely
If you plan to sell shares or property, consider the timing:
- The CGT annual exempt amount is £3,000 in 2025/26
- Married couples can combine allowances (£6,000 total)
- Holding assets longer or selling in phases may keep gains below the threshold
Investing through ISAs avoids CGT altogether.
A Word of Caution
While the potential savings are substantial, it’s important to remember:
- The £45,000 allowance is not yet law, and could change based on political shifts
- Overreacting based on speculation could lead to unintended tax consequences
- Tax planning should align with your long-term financial goals, not just the next budget announcement
That said, all the strategies we’ve shared are 100% legal and effective under existing tax rules. Even if the allowance remains at £12,570, you’ll still benefit by reducing your taxable income and securing more of your hard-earned money.

FAQs about This 2025 Tax Strategy Could Save You £45,000
Is the £45,000 tax-free allowance confirmed?
No. As of April 2025, the Personal Allowance remains at £12,570. The £45,000 figure is part of a proposed tax reform and has not been approved or passed into legislation.
Can I really save £45,000?
No. The figure refers to the amount of income you could earn tax-free, not the savings. At most, you could save around £6,486 per year in tax, depending on your income level.
When will we know if the allowance will change?
Likely updates will come in the Autumn Budget 2025 or earlier if a snap general election brings tax reform. Stay tuned to HM Treasury updates.
Should I change my salary or defer bonuses?
Only after consulting a tax adviser. This strategy can be beneficial but depends on income timing, employment contracts, and HMRC guidance.
Are ISAs or pensions better for tax saving?
It depends on your goals:
- Pensions offer upfront tax relief and long-term growth, but access is limited until age 55+
- ISAs are more flexible and provide tax-free withdrawals anytime
Ideally, use both to diversify your tax-free income streams.
