AVC Pensions Explained: Boost Your Pot Tax-Free in 2026/27

Quick answer

An AVC (Additional Voluntary Contribution) is an extra payment into your workplace pension on top of your standard contributions. You get Income Tax relief at your marginal rate, so GBP 100 in your pot costs a basic-rate taxpayer GBP 80, a higher-rate payer GBP 60, and an additional-rate payer GBP 55. AVCs share the GBP 60,000 annual allowance, grow largely tax-free, and are accessed under normal pension rules.

How AVCs work

When you join a workplace pension you agree a standard contribution, usually a fixed percentage of salary, and your employer typically adds its own. An AVC is anything you choose to pay above that baseline. The defining feature is the tax relief: every pound you contribute is topped up so that your taxable income falls by the gross amount.

There are three common mechanisms, and which one your scheme uses changes the maths:

• Relief at source. You pay from net (after-tax) pay and the scheme reclaims 20% basic-rate relief from HMRC and adds it to your pot. Higher and additional-rate taxpayers claim the extra relief through Self Assessment or by contacting HMRC.
• Net pay arrangement. Your AVC is deducted from gross pay before Income Tax is calculated, so you get full relief at your marginal rate immediately. There is no separate claim to make.
• Salary sacrifice. You formally give up part of your gross salary in return for an employer pension contribution. This saves Income Tax and employee National Insurance, and is usually the most efficient option.

The 2026/27 tax relief in numbers

Relief follows your highest rate of Income Tax. The table below shows the real cost of getting GBP 1,000 into your pension for England, Wales and Northern Ireland taxpayers in 2026/27.

Scottish taxpayers get relief at their own band rates, which range from the 19% starter rate up to 42%, 45% and the 48% top rate. The principle is identical - relief at your marginal rate - but the exact net cost differs.

The single most valuable case is the 60% effective band. Because the Personal Allowance of GBP 12,570 is tapered away by GBP 1 for every GBP 2 of income above GBP 100,000, every pound earned between GBP 100,000 and GBP 125,140 is effectively taxed at 60%. An AVC that brings your adjusted income back below GBP 100,000 reclaims that allowance, so GBP 1,000 in your pension can cost as little as GBP 400 net.

The annual allowance and your earnings limit

Tax relief is not unlimited. Two ceilings apply.

First, the annual allowance of GBP 60,000 for 2026/27 caps the total that can go into all your pensions in a year with relief - that includes your standard contributions, your employer's contributions and your AVCs combined. Exceed it and you can face an annual allowance charge that effectively removes the relief on the excess.

Second, your relief is limited to your relevant UK earnings for the year. You cannot get relief on more than you earn (beyond a small basic floor for non-earners), so very large AVCs from modest salaries may not all qualify.

Two special cases narrow the GBP 60,000 figure:

• The Money Purchase Annual Allowance (MPAA) of GBP 10,000 applies once you have flexibly accessed a defined-contribution pension.
• A tapered annual allowance can reduce the GBP 60,000 for high earners, depending on total income.

AVCs versus an ISA

The most common question is whether to use AVCs or an ISA. They are tax-advantaged in opposite directions.

A simple way to think about it:

• If you are a higher or additional-rate taxpayer now but expect to draw income at the basic rate in retirement, the pension usually wins - you get 40% or 45% relief going in and pay 20% on much of it later, with a tax-free lump sum on top.
• If you need access before pension age or value flexibility, an ISA is hard to beat.
• Many people sensibly do both, using AVCs for the long-term, tax-relieved core and an ISA for medium-term goals.

A Lifetime ISA adds a 25% government bonus of up to GBP 1,000 a year for those saving towards a first home or retirement, which can sit alongside an AVC strategy.

The salary sacrifice advantage

If your employer offers salary sacrifice for AVCs, it is normally the most efficient route. By reducing your gross salary, you cut both Income Tax and the employee National Insurance you pay - 8% on earnings between GBP 12,570 and GBP 50,270, and 2% above that. Net pay and relief-at-source AVCs do not save NI.

For example, a higher-rate taxpayer sacrificing GBP 1,000 of salary saves GBP 400 in Income Tax and GBP 20 in the 2% NI band, so the net cost of getting GBP 1,000 into the pension is around GBP 580 rather than GBP 600. Some employers also pass on part of their own 15% employer NI saving, boosting the contribution further.

Salary sacrifice does reduce your headline salary, which can affect borrowing assessments, some benefits and life cover based on salary. Confirm the details with your payroll team before signing up.

Accessing your AVC pot

AVCs follow standard pension access rules. You generally cannot touch the money until the minimum pension age set by legislation and your scheme, which sits below State Pension age but is scheduled to rise over time. From that point you can typically take a tax-free lump sum, subject to the usual limits, and use the remainder for income through drawdown or an annuity.

Withdrawals beyond the tax-free element are taxed as income in the year you take them, using the same bands as your salary - 20%, 40% and 45% in England, Wales and Northern Ireland. Planning the timing of withdrawals to stay within lower bands is a core part of retirement strategy.

Who benefits most from AVCs

AVCs suit anyone with spare income who wants to build retirement savings tax-efficiently, but some groups gain disproportionately:

• Higher and additional-rate taxpayers, who claim 40% or 45% relief.
• Earners in the 60% trap between GBP 100,000 and GBP 125,140, where AVCs reclaim the tapered Personal Allowance.
• Those approaching retirement who want to fill unused allowance via carry forward.
• Employees whose schemes offer salary sacrifice, adding the NI saving.

If you are self-employed rather than an employee, the AVC label does not apply, but the same logic works through a personal pension or SIPP. Use our self-employed tax calculator to see how much spare profit you could redirect into a pension with full relief.

Bottom line

AVCs are one of the most powerful tax-relief tools available to UK employees. Within the GBP 60,000 annual allowance, every contribution is topped up at your marginal rate, growth is largely tax-free, and salary sacrifice can add a National Insurance saving on top. The trade-off is access: the money is locked until pension age and most of it is taxed as income on the way out. Weigh that against the flexibility of the GBP 20,000 ISA allowance, model the figures with our pension and take-home pay calculators, and consider regulated advice for large or complex contributions.
