Structuring your finances tax efficiently in 2026/27

Knowing how to structure your money tax efficiently means organising your income, savings and investments to make full use of the UK’s tax-free allowances. Structuring your finances tax efficiently, using the personal allowance, ISAs and pension relief can significantly impact your financial future. This guide covers the main tax-free allowances for 2026/27 and practical strategies to minimise your tax bill.

UK tax-free allowances

The UK tax system provides a range of annual tax allowances that let individuals earn certain types of income tax-free. Used together, these allowances can shelter a significant amount of income from tax each year. The main allowances for the tax year 2026/27 are:

Tax-free allowance	Amount	Details of income
Personal allowance (Tax code of 1257L)	£12,570	UK individuals can earn income up to £12,570 a year tax-free
Capital gains allowance	£3,000	Profit on sale of assets – such as shares, property and art
Personal savings allowance – Basic rate taxpayers	£1,000	Interest on savings
Personal savings allowance – Higher rate taxpayers	£500	Interest on savings
Starting rate savings allowance	£5,000	Available in full if your other income is less than £12,570
Dividend allowance	£500	Dividend income from shares
Trading allowance	£1,000	For trading or casual income
Rent a room scheme	£7,500	Income from letting a furnished room in your home
Marriage allowance	£1,260	Couples can save up to £252 in tax

When your income exceeds an allowance threshold, the amount above the threshold is taxed at the rate applicable to that type of income. Employment income, savings interest, and pension income are taxed at standard income tax rates, while capital gains and dividends have their own separate rates. The tax band your total income falls into determines which rate applies. The tax rates are listed below for all three income types across the basic, higher, and additional rate tax bands.

Tax rates on income exceeding the allowance thresholds

Basic rate taxpayers:

• Income – 20%
• Capital gains – 18%
• Dividends – 10.75%

Higher rate taxpayers:

• Income – 40%
• Capital gains – 24%
• Dividends – 35.75%

Additional rate taxpayers:

• Income – 45%
• Capital gains – 24%
• Dividends – 39.35%

Tax bands and rates

Tax band	Range	I	CG	D
Personal allowance	up to £12,570	0%	0%	0%
Basic rate	from £12,570 to £50,270	20%	18%	10.75%
Higher rate	from £50,271 to £125,140	40%	24%	35.75%
Additional rate	Over £125,140	45%	24%	39.35%

Column “I” covers the broadest category of income. The rates apply to employment and self-employment earnings, savings interest, pension income, and property income falling within each tax band. If you have more than one of these income types, they are added together to determine your overall tax band.

Column “CG” covers capital gains tax, which is the tax due on profits from selling assets such as shares, property, or valuables above the £3,000 annual allowance. Column “D” covers dividend income above the £500 allowance. Unlike income tax, neither capital gains nor dividends are added to your other income to determine your tax band. They sit on top of your income and are taxed at the rate corresponding to whichever band they fall into.

The UK uses a marginal tax system, which means you pay the higher tax rate only on the income that falls within the higher band, not on everything you earn. For example, if you earn £55,000, you don’t pay 40% on the full amount. You pay 0% on the first £12,570, 20% on the next £37,700, and 40% only on the remaining £4,730 that exceeds the £50,270 threshold.

Future tax increases

From April 2027, the tax rate for savings interest and property income is increasing by 2%. Basic rate taxpayers will see their rate rise from 20% to 22%, higher rate taxpayers from 40% to 42%, and additional rate taxpayers from 45% to 47%. This change makes ISAs, which shelter interest from tax, a valuable tax-saving tool.

As mentioned, income is taxed in a specific order on Self Assessment tax returns, and you can learn more using the link below:

A breakdown of the tax allowances

Personal allowance

If you have the standard tax code 1257L, you receive the full personal allowance of £12,570, meaning the first £12,570 of your income is tax-free. The next £37,700 is taxed at 20%, taking you up to the £50,270 higher rate threshold. Income between £50,270 and £125,140 is taxed at 40%, and anything above £125,140 is taxed at the additional rate of 45%.

Capital gains tax

Any capital gains over £3,000 from the sale of taxable assets, such as shares, property, and art, are taxed at 18% for basic rate taxpayers and 24% for higher and additional rate taxpayers.

Dividends

The first £500 of dividends are tax-free for all taxpayers, regardless of their tax bracket. Any dividends over the £500 allowance are subject to tax of 10.75% if they fall within the basic rate tax band (up to £50,270). Dividend income that falls in the higher rate band is taxed at 35.75%, while dividend income is taxed at 39.35% for additional rate taxpayers (income above £125,140).

Savings interest

Basic rate taxpayers receive a personal savings allowance of £1,000 which lets them earn up to this in interest tax-free. Interest income above the allowance is taxed at 20% (22% from April 2027). Higher rate taxpayers have a reduced allowance of £500 a year, and pay tax of 40% on interest over this (42% from April 2027). Additional rate taxpayers have no allowance and pay tax of 45% (47% from April 2027) on their interest from savings.

Starting rate for savings allowance

If your other income, such as wages and pensions, is less than £17,570, you may benefit from the starting rate for savings. With this allowance, you can earn up to £5,000 in savings interest tax-free, as long as your other income for the year is less than £17,570. The allowance is reduced by £1 for every £1 of other income earned over £12,570.

For example:

• If your other income is £12,570 (equal to the Personal Allowance), you get the full £5,000 allowance.
• If your other income is £15,070, your allowance reduces to £2,500.
• If your other income is £17,570 or more, you get no allowance.

You still receive the £1,000 personal savings allowance, meaning you can earn an additional £1,000 in tax-free interest in the above examples.

Rent a room

You can rent out furnished accommodation in your home under the rent a room scheme and earn up to £7,500 per year tax-free. You can learn more about this by visiting HMRC’s website:

Side hustles and the trading allowance

If you have income from casual work or self-employment, you can earn £1,000 a year tax-free. If you earn more than the £1,000 allowance, you will need to register with HMRC and complete an annual Self Assessment tax return.

Marriage allowance

The marriage allowance lets you transfer up to £1,260 of your personal allowance to your partner, potentially reducing their tax by up to £252. To be eligible for this allowance, the lower earner of the couple usually needs to earn less than the personal allowance of £12,570.

Tax structuring strategies

Taking time to look at your finances strategically can have long-term benefits, from reducing the amount of tax you pay to increasing your overall wealth. It’s important to structure your finances to benefit from the tax-free allowances and make use of tax-free wrappers like ISAs. The strategies below include some of the most common and effective ones that can be adapted to your personal financial circumstances.

ISAs

An ISA, or individual savings account, provides a tax-free wrapper for saving and investing. An ISA lets you earn interest, dividends and capital gains on your savings and investments tax-free. You can save up to £20,000 into ISAs each year, and when you withdraw money, it’s completely tax-free. From April 2027, a cap of £12,000 applies to new cash contributions into ISAs for those under 65.

Capital gains on assets

If you hold assets outside an ISA, consider spreading the sale of the assets over several tax years to reduce your tax liability. By keeping the profit on annual sales within the capital gains allowance of £3,000, you can eliminate any tax liability.

For example, if you hold shares outside an ISA with a total gain of £9,000, selling them all in one tax year would leave £6,000 above the allowance and subject to capital gains tax. Spreading the sales over three tax years, and only realising £3,000 of gain each year, could mean no capital gains tax is due at all.

Transfer stocks and shares to ISAs

Consider gradually transferring shares held in a regular investment account into an ISA. As long as the profit from selling the shares is within the £3,000 capital gains allowance and the total value of the shares is below the £20,000 ISA limit, you should be able to transfer them into an ISA without paying tax.

Dividend income

The tax-free dividend allowance is just £500, which makes ISAs particularly appealing for protecting dividend income from tax. This is especially beneficial for investments in shares with high dividend yields.

Reducing dividend tax by making pension contributions.

Contributing to a personal pension not only benefits your pension pot but can reduce the tax you pay on dividends by increasing your basic rate tax threshold. The example below assumes someone earning £51,000 a year from employment receives dividend income of £2,000 outside of an ISA. If they made contributions of £3,000 into a personal pension plan, their basic rate threshold increases to £53,270, which decreases the dividend tax rate from 35.75% to 10.75%, saving them £375 in tax.

	Without pension contributions	With a £3,000 pension contribution
Basic rate threshold	£50,270	£53,270
Dividends tax rate	35.75%	10.75%
Tax on £1,500 dividend	£536	£161
Saving		£375

Without any pension contributions, the first £500 of dividends is tax-free, with the remaining £1,500 taxed at the higher rate of 35.75%, or £536 in tax. With the pension contribution increasing the basic rate band, the £1,500 of dividends that aren’t covered by the dividend allowance are now taxed at the basic rate of 10.75%.

In addition to the reduction in dividend tax, personal pension contributions receive tax relief. Keep in mind that while this strategy helps with dividend tax, it doesn’t impact how much capital gains tax you pay.

SIPP – Self-invested personal pension

Personal pension contributions receive tax relief at your marginal income tax rate, with HMRC adding tax relief on top of what you contribute. They are effectively reimbursing the tax already paid on that money. The marginal rates are:

• Basic rate taxpayers receive 20% relief – a £1,000 personal pension contribution costs £800 after tax relief
• Higher rate taxpayers receive 40% relief – a £1,000 personal pension contribution costs £600 after tax relief

Income and capital gains from investments held within a SIPP are not subject to tax. This means they are not subject to capital gains or dividend tax, which means more of your money compounds over time. When you access your pension, you can take 25% of the total fund tax-free as a lump sum or withdraw it over time. The remaining 75% of the pension pot may be subject to income tax depending on your circumstances and is taxed at your marginal tax rate at that point in time.

Some FAQs

What is an adjusted tax code?

The standard tax code is 1257L, which gives you the full £12,570 personal allowance. Your code might be different if you’ve underpaid tax in a previous year, or if you receive taxable benefits from your employer, such as a company car or private medical (known as benefits in kind), or if you have other income that HMRC taxes through your tax code. Any of these adjustments will reduce your tax allowance and change your tax code.

For instance, a tax code of 950L means:

• Your tax-free allowance is reduced to £9,500 – this is the maximum you can earn tax-free.
• You will pay 20% tax on the next £37,700 of earnings
• Any income above £47,200 (£9,500 + £37,700) is taxed at 40%

If you are unsure why your tax code has changed, you can check it via your HMRC personal tax account at GOV.UK.

What happens to my personal allowance if I earn over £100,000?

If you earn over £100,000, your personal allowance is gradually withdrawn, creating the high earner 60% tax band. For every £2 earned above £100,000, you lose £1 of your personal allowance. Once your income reaches £125,140, the allowance is lost entirely.

This creates an effective tax rate of 60% on income between £100,000 and £125,140, because you are paying 40% tax on that income while simultaneously losing the personal allowance that was sheltering other income from tax.

One of the most effective ways to reduce or avoid this is through personal pension contributions, which reduce your adjusted net income, which is the figure HMRC uses to calculate allowance withdrawal. For example, if you earn £110,000 and contribute £10,000 to a personal pension, your adjusted net income falls to £100,000, and you still receive your full personal allowance. You also receive 40% tax relief on the pension contributions, making this a great strategy for earners in this band. Making Gift Aid donations is another strategy to reduce your adjusted net income.

What is adjusted net income and why does it matter?

Adjusted net income is your total income minus certain deductions, usually personal pension contributions and Gift Aid donations. HMRC uses this figure instead of your gross income to calculate adjustments to your personal allowance, child benefits, and your entitlement to the personal savings allowance. If your gross income is above a key threshold that impacts your tax exemptions, it is worth checking whether pension contributions could reduce your adjusted net income below that threshold.

What is the most tax-efficient way to save money in the UK?

For most people, the most tax-efficient way to save is through an ISA. You can save or invest up to £20,000 per tax year, and all interest, dividends, and capital gains within an ISA are completely tax-free. All money you withdraw from an ISA is tax-free too. From April 2027, the maximum new contributions you can put into a cash ISA will decrease to £12,000 a year, with the remaining £8,000 required to go into stocks and shares. For longer-term savings, a pension is efficient because contributions receive upfront tax relief, effectively increasing the amount you save.

Is it better to use an ISA or a pension?

This depends on your goals and time frames. Pensions offer upfront tax relief, which increases the total contribution. If you invest £80, HMRC adds another £20, but you can’t access the money until age 57 (rising to 58 in 2028). You do benefit from additional compounding returns on the tax relief. Pensions are partly taxable once you start withdrawing funds, with 25% tax-free. ISAs have no upfront tax relief, but the money is accessible at any time. All income and capital gains earned on ISA money are tax-free, as are withdrawals. For most people, the best approach is to use both: a pension for long-term retirement saving and an ISA for medium-term goals or accessible tax-free growth.

And finally…

Structuring your money tax efficiently can significantly impact your long-term wealth. By making full use of your personal allowances, ISAs, and pension contributions, you can minimise your tax liability while building your savings and investments for the future. Tax rules and allowances can change with each tax year, so it’s advisable to review your tax planning strategy annually and consider seeking professional financial advice for your specific circumstances.
