Carry forward: using allowance you didn't use

Unused Annual Allowance from the last three years doesn't have to go to waste.

Most people never come close to the Annual Allowance, so carry forward passes them by entirely. But for anyone with a lump sum to deal with — a bonus, an inheritance, a business sale, a good year of self-employment — it's one of the more useful rules in the pension system, and it's routinely missed.

The basic idea

The Annual Allowance limits how much can go into your pensions each tax year with tax relief. The standard allowance is £60,000, and that figure includes everything: your contributions, your employer's, and tax relief.

If you don't use it all in a given year, the unused portion doesn't disappear immediately. You can carry it forward for up to three tax years and use it later.

So in a year where you have more to contribute than the annual limit allows, you may be able to use this year's allowance plus whatever's left over from the previous three.

The two conditions

You must have been a member of a registered pension scheme in the years you're carrying forward from. Membership, not contributions — a scheme you were in but didn't pay into still generates unused allowance to carry forward. But a year in which you had no pension at all generates nothing.

Your contribution can't exceed your earnings in the year you make it. This is the constraint that catches people. Tax relief on personal contributions is limited to 100% of your relevant UK earnings for that tax year. So someone with £150,000 of carry forward available but £40,000 of earnings can only personally contribute £40,000 with relief.

Employer contributions aren't restricted by your earnings in the same way, which is why this rule bites differently for company directors than for employees.

How the order works

You use the current year's allowance first, then the oldest carried-forward year, then work forward. Unused allowance older than three years is simply lost.

The practical implication: allowance from three years ago is about to expire. If it's going to be used, it has to be used now.

Where it actually helps

A bonus you'd rather not be taxed on. Particularly where it pushes you into a higher band, or across £100,000 where the Personal Allowance tapers away.

Self-employed income that varies. Lean years generate unused allowance; good years can mop it up.

A business sale or windfall. Subject to the earnings limit, which is often the binding constraint here.

Anyone catching up. People who couldn't afford to contribute in their thirties and can in their fifties are precisely who this rule helps.

High earners whose allowance is tapered. Carry forward can be used alongside a tapered allowance, though the calculation gets fiddly and the amounts carried forward are themselves reduced by the taper in those years.

Where it doesn't help

If you've triggered the Money Purchase Annual Allowance, carry forward can't be used for money purchase contributions at all. Taking taxable income flexibly from a defined contribution pension drops your allowance to £10,000 and closes this door permanently. If there's any chance you'll want to make a large contribution later, that's a significant reason not to trigger the MPAA casually — see Which pot do you spend first?.

If you weren't in a pension scheme in the earlier years, there's nothing to carry.

If your earnings are lower than the amount you want to contribute personally, the earnings cap limits you regardless of how much allowance is available.

Working out what you've got

You need, for each of the last three tax years: the Annual Allowance that applied to you, and the total that went into all your pensions. The difference is what's available.

That means gathering contribution records from every scheme, including employer contributions, which people routinely forget to count. The Pension Contribution Calculator will do the arithmetic once you have the figures.

Where a tapered allowance applies in any of those years, the calculation becomes considerably harder and is worth having checked properly.

The timing point

Carry forward operates on tax years, and the oldest year drops out on 6 April. Allowance you could have used on 5 April is gone on the 6th.

If you have a large contribution in mind and unused allowance from three years back, the deadline is real and it doesn't move.

If you're in the NHS Pension Scheme

NHSBSA statements are produced against the standard allowance and can't see private practice or other income, so the carry forward figure they imply may be too generous. NHS annual allowance carry forward opens the NHS calculator at the carry forward step.

This article is for general education only and isn't personal advice. Carry forward calculations depend on your contribution history across all schemes and become complex where a tapered allowance applies — worth getting checked before you rely on a figure.
