Pension Carry Forward for Contractors - The Three-Year Rule and High-Profit Planning

The annual allowance and why it matters to contractors

The annual allowance (AA) is the maximum that can go into your pensions in a tax year without triggering a tax charge. For 2026/27 the allowance is £60,000 across all your pension schemes combined. That sounds generous, but for a contractor building a serious pension pot in a high-profit year, or planning a structured exit, a single year's £60,000 can feel restrictive.

The carry-forward rule eases that. Instead of being limited to £60,000 in any one year, you can use unused allowance from the previous three tax years, potentially reaching £240,000 in a single year if you carried forward the full £60,000 from each of those years.

The rule turns pension planning from a year-by-year constraint into a multi-year strategy. For a contractor on a variable income, that flexibility is genuinely useful.

How the three-year carry-forward works

Carry-forward follows a fixed order. You use the current year's allowance first, then unused allowance from the previous three tax years, taking the earliest year first. You cannot look back more than three years.

The mechanics are straightforward. If you contributed nothing in 2023/24, 2024/25 and 2025/26, you have £60,000 of unused allowance from each of those years. In 2026/27 you have £60,000 of current-year allowance plus that £180,000 of carry-forward, totalling £240,000. If you then contribute £180,000 in 2026/27, you use the £60,000 current-year allowance first, then £60,000 from 2023/24 (the earliest year), then £60,000 from 2024/25, leaving the £60,000 from 2025/26 still available to carry into later years.

One timing point is easy to miss. Unused 2023/24 allowance can only be carried as far forward as 2026/27. Whatever is left of it after 2026/27 is lost, because by 2027/28 the three-year window has moved on to 2024/25, 2025/26 and 2026/27. That is why using the earliest year first matters: it spends the allowance that is closest to expiring.

Carry-forward is distinct from the annual allowance itself. The allowance can be reduced if your income is high (the taper, covered below), and that reduction feeds through to what you can carry forward from a tapered year. The money-purchase annual allowance can further restrict it. Absent those, the three-year window is a simple calendar: back three years only, earliest first.

Employer versus personal contributions: why employer wins for PSC directors

Not all pension contributions are equal for tax purposes. For an in-depth look at PSC tax planning and extraction, see our guide to PSC limited company contractor tax.

A personal contribution (money you pay in from your own salary or savings) is capped at 100 per cent of your relevant UK earnings in the year. Relevant earnings are broadly salary, not dividends. A contractor on a salary of £8,000 can make a personal contribution of at most £8,000 that year, however much profit the company makes.

An employer contribution (money the company pays in on your behalf) has no such cap. It is limited only by the annual allowance (plus carry-forward) and the wholly-and-exclusively test (the contribution must be a genuine cost of the business, not disguised profit withdrawal). The company deducts the contribution against its profit for corporation tax, so a £60,000 employer contribution on a £100,000 profit reduces the taxable profit and saves corporation tax at the applicable rate (19 to 26.5 per cent depending on profit level).

For a PSC director on a low salary and high dividends, the employer route is the only way to shelter large amounts in a pension. A director on £6,708 salary (the LEL, chosen to secure a qualifying NI year) can make only a £6,708 personal contribution. An employer contribution of £60,000 faces no earnings restriction.

That is why the employer contribution is described as the contractor's biggest tax-efficient extraction lever. It is the most direct way to move profit out of the company, free of NIC and untaxed on the director when paid in, into a long-term savings vehicle.

The tapered annual allowance: the high-earner trap

The £60,000 allowance does not apply equally to everyone. For high-earning contractors it tapers. This interaction with dividend and salary planning is explored in our guide to contractor pension employer contributions.

The taper applies where two tests are both met: threshold income exceeds £200,000 AND adjusted income exceeds £260,000. The two measures are different and easy to confuse, so it is worth stating them carefully. Threshold income is broadly your taxable income for the year with most pension contributions stripped out. Adjusted income takes a similar starting point but adds your pension savings back in, including employer contributions. Both definitions have detailed adjustments, so treat the descriptions here as directional and confirm your own figures with an adviser.

Where both limits are crossed, the allowance reduces by £1 for every £2 of adjusted income above £260,000, down to a floor of £10,000. The allowance will not taper below that, however high income rises.

An example: a contractor with adjusted income of £280,000 is £20,000 above the £260,000 limit, so the allowance reduces by £10,000, from £60,000 to £50,000. At adjusted income of £320,000 the reduction is £30,000, taking the allowance to £30,000. At £360,000 or above the allowance is at the £10,000 floor.

The trap is that the taper can be sharp and is easy to miss. A high-earning contractor who is unaware of it can make a contribution they believe is within the limit and find at Self Assessment that they have an annual-allowance charge. Because adjusted income adds employer contributions back in, a large employer contribution does not reduce adjusted income and cannot, on its own, lift you back out of the taper. The interaction with dividends and other income is genuinely complex, and is one to model with an adviser before committing.

The money-purchase annual allowance: the flexible-access trap

A separate and often overlooked trap is the money-purchase annual allowance (MPAA).

If you have flexibly accessed a defined-contribution (money-purchase) pension, you trigger the MPAA. Flexibly accessing broadly means taking an income through flexi-access drawdown, or taking a lump sum beyond the tax-free element. Once triggered, contributions to defined-contribution pensions are limited to £10,000 a year, and carry-forward is lost for those contributions.

The MPAA applies to defined-contribution schemes, not defined-benefit pensions. For most contractors, who use defined-contribution personal pensions or receive employer contributions into a money-purchase scheme, the MPAA is the relevant limit.

The trap occurs when a contractor flexibly accesses a pension (say, drawing an income from an old pot from a previous employer) and then later wants to make a large contribution into a new scheme. The MPAA locks new defined-contribution contributions to £10,000 a year, with no carry-forward, turning what looked like a £60,000-plus opportunity into £10,000. Some contractors do not realise they have triggered it, perhaps because the access happened years earlier. If you have drawn from any pension, confirm your position with your adviser before planning a large contribution.

Once triggered, the MPAA does not go away. It applies to all future defined-contribution contributions unless the rules change.

Why low-salary, high-dividend contractors benefit most from carry-forward

The typical PSC director structure is a low salary (commonly between the secondary threshold of £5,000 and the LEL of £6,708) combined with dividends. This limits National Insurance on the salary and lets the bulk of profit come out as dividends (taxed at 10.75 per cent in 2026/27, with no NIC). For more on the wider salary and dividend split, see our guide to PSC limited company contractor tax.

A low salary means a low personal-contribution cap. A director on £6,708 salary can contribute only £6,708 personally. The company, though, can make an employer contribution with no salary-based cap, subject only to the annual allowance and carry-forward.

Over a run of years with variable profit, a low-salary director might make small contributions (or none) in lean years, building carry-forward, and then deploy it in a profitable year. A worked example shows how the ordering works:

• 2023/24: a quiet year. Allowance £60,000, employer contribution £0, so £60,000 of unused allowance is available to carry forward.
• 2024/25: a modest year. Allowance £60,000, employer contribution £20,000, leaving £40,000 unused.
• 2025/26: a moderate year. Allowance £60,000, employer contribution £30,000, leaving £30,000 unused.
• 2026/27: a strong year, company profit well up. The director has £60,000 of current-year allowance plus carry-forward of £60,000 (from 2023/24), £40,000 (from 2024/25) and £30,000 (from 2025/26): £190,000 in total.

If the company makes a £190,000 employer contribution in 2026/27, the allowance is used in the set order: £60,000 current year first, then £60,000 from 2023/24 (the earliest year), then £40,000 from 2024/25, then £30,000 from 2025/26. That comes to exactly £190,000, with no annual-allowance charge. Had the contribution been smaller, the earliest year would still be used first, and any 2023/24 allowance left unused after 2026/27 would be lost, because it cannot be carried beyond the three-year window. This is a legitimate way to deploy a run of underused allowance in a high-profit year, but the figures should be confirmed against your actual statements and your adviser before contributing.

This pattern is common among contractors: income is variable, and the ability to under-contribute in lean years and catch up in strong years, without an annual-allowance charge, is a real advantage of the carry-forward rule.

Planning for high-profit years and one-off contributions

A high-profit year creates a corporation-tax bill. If the company retains profit rather than distributing it as salary or dividend, that profit is charged to corporation tax at 19 to 26.5 per cent depending on the profit level and any marginal-relief interaction.

An employer pension contribution is deductible against the company's profit before corporation tax is calculated. A £60,000 contribution on a £100,000 profit reduces the taxable profit to £40,000, saving corporation tax of £11,400 (at 19 per cent) up to £15,900 (at 26.5 per cent) depending on where the profit sits in the marginal band.

The contribution is also not taxed as income on the director in the year it is paid in (subject to the annual allowance), and the pension pot then grows in a tax-advantaged environment until retirement.

Where the company is heading for an exit (a sale or a solvent liquidation), a final large employer contribution before the exit can shelter profit that would otherwise be extracted as a dividend (10.75 per cent in 2026/27) or salary (20 per cent income tax plus 8 per cent employee NIC, with employer NIC on top). A pension contribution avoids both the income tax and the NIC, though the money is then locked in the pension until retirement, with only limited exceptions.

This is where carry-forward becomes strategic. If a contractor has accumulated unused allowance over several years, a single large contribution in the exit year can deploy that allowance without an annual-allowance charge, sheltering a meaningful amount of profit efficiently.

The wholly-and-exclusively test and when contributions are allowed

An employer pension contribution is deductible against company profit for corporation tax only where it is paid wholly and exclusively for the purposes of the business. The deduction is also given on a paid basis, meaning the contribution has to be actually paid in the accounting period, not merely accrued.

In practice this is rarely a problem for an ordinary contribution. An employer pension contribution for a working director is a standard business cost, and HMRC does not usually challenge it on this ground unless the contribution looks like disguised profit extraction or part of an avoidance arrangement. The company does need genuine resources to fund it: a contribution provided for in the accounts but not actually paid is deductible only in the period it is paid.

The test also underpins the difference between employer and personal contributions. A personal contribution from the director's own funds is not a company expense; it uses salary or dividend already extracted. An employer contribution is paid by the company and is deducted before corporation tax is calculated.

Recording the carry-forward: what you need to track

Carry-forward is not automatically calculated for you. You need to be able to evidence the unused allowance you are relying on, and to report any annual-allowance charge through Self Assessment if one arises.

Your pension provider sends an annual statement showing contributions paid in the year and, usually, your remaining allowance. Keep these statements for all years and all schemes. If you have a pension from a previous employer, ask that scheme's administrator for your historical position; any unused allowance from the relevant years is available to carry forward.

Where your contributions in a year stay within your available allowance (current year plus carry-forward), there is no charge and no separate claim is needed, but you should keep the working that shows how the carry-forward stacked up. If a charge does arise, it is calculated and reported through Self Assessment.

Many contractors ask their accountant to confirm this. The carry-forward calculation is not complicated, but accuracy matters, because a misjudged contribution can trigger a charge that removes the relief you were aiming for.

The interaction with corporation tax and dividend planning

An employer pension contribution affects the company's bottom line and so the profit available for dividends. A £60,000 contribution reduces the company's taxable profit by £60,000 and also reduces the post-tax profit available for extraction, because it is paid before corporation tax is calculated. The wider interaction of dividends with corporation tax is covered in our contractor pension employer-contribution guide.

Take a company with profit of £100,000. A £60,000 employer contribution leaves £40,000 of taxable profit. Corporation tax at 19 per cent is £7,600, leaving £32,400 of post-tax profit. A dividend of that £32,400 attracts dividend tax at 10.75 per cent (2026/27) of £3,483, leaving £28,917 in the director's hands, while the £60,000 sits in the pension.

If instead the whole £100,000 were taken as dividend, the company would pay corporation tax at 19 per cent (£19,000), and dividend tax at 10.75 per cent on the £81,000 distributed would be £8,708, leaving £72,292. No pension contribution is made.

The pension route takes £60,000 out of immediate income-tax and dividend-tax exposure, at the cost of locking it away until retirement. For a contractor with enough income from other years or sources, that trade is usually more tax-efficient. For one who needs maximum current income, the dividend route is the practical choice regardless.

The taper interacts here too, but not in the way it is sometimes described. Because adjusted income adds employer contributions back in, a large employer contribution does not pull adjusted income down and cannot by itself unwind the taper. What carry-forward does is let a high-profit year use unused allowance from earlier years, so the contribution can be larger without a charge. Whether the taper bites in any given year is a separate calculation that turns on your total income, and high earners should work it through with an adviser.

Carry-forward and company exits: the strategic window

Contractors often plan an exit, either a sale to a buyer or a solvent liquidation. The exit creates a planning window. For more on company structure and exit planning, see our PSC limited company contractor tax guide.

In the final year or two before exit, a contractor may prefer not to leave profit sitting in the company, since it will be extracted anyway and extraction on a sale or liquidation carries its own tax consequences. A large employer pension contribution in that window can shelter profit that would otherwise be extracted and taxed. The contribution is irreversible, but the corporation-tax saving is immediate.

This is where accumulated carry-forward is most valuable. If a contractor has not used their full allowance in earlier years and has built up an unused balance, the exit year allows that balance to be deployed in a single large contribution, provided it has not already been consumed.

The exit raises one more point: the MPAA. A contractor who retires or semi-retires after the exit and starts drawing from the pension will trigger the MPAA on any flexible access, capping future defined-contribution contributions at £10,000. For someone who exits and then starts another venture, that can be a real constraint, so the sequencing of contributions and drawings is worth planning in advance.

Practical steps: modelling your carry-forward

To use carry-forward well, you first need to know what allowance you actually have available.

First, gather your annual benefit statements from every pension scheme (personal pension, any group scheme from previous employment, and any others). These should show your contribution history and your remaining allowance.

Second, confirm whether you have triggered the MPAA. If you have flexibly accessed any defined-contribution pension, note when and how much; that determines whether the £10,000 cap applies to your future contributions.

Third, estimate your income for the current year. If you are in the tapered-allowance band (threshold income over £200,000 and adjusted income over £260,000), model the taper and confirm your effective allowance for the year.

Fourth, decide on the contribution. Will you use the current-year allowance only, or deploy carry-forward? If deploying carry-forward, check that your provider will accept a contribution above the single-year allowance, as a few older schemes have restrictions.

Fifth, work with your accountant or adviser to confirm the contribution is properly deducted in the corporation-tax computation and that any Self Assessment reporting is right.

For contributions up to £60,000 this is straightforward. For larger contributions using carry-forward, or where the taper is in play, professional advice earns its keep, because the sums are large and a misjudged contribution can trigger an unnecessary charge.

The carry-forward rule versus rising dividend rates

The dividend ordinary rate rose from 8.75 per cent to 10.75 per cent from 6 April 2026, and the upper rate from 33.75 per cent to 35.75 per cent. That makes the pension route more attractive relative to dividend extraction than it was.

A contractor who would have taken profit as dividends in 2026/27 now meets the higher 10.75 per cent rate (or 35.75 per cent in the higher-rate band). An employer pension contribution avoids that dividend tax, gives a corporation-tax deduction, and is not taxed on the director when paid in. Carry-forward lets a contractor reach back to allowance from earlier, lower-dividend-rate years, which makes a larger one-off contribution feasible in a single year without a charge.

Limits and caveats

The carry-forward rule is generous, but it has real limits.

You can only look back three years. Anything older is lost. A contractor who has under-contributed for a decade cannot reach the earliest years; only the most recent three count.

The allowance you carry forward from a tapered year is the tapered figure that actually applied that year, not £60,000. This is fiddly to model and needs careful tracking.

The MPAA can cut defined-contribution carry-forward to £10,000 a year if you have flexibly accessed a DC pension. That restriction is, in practice, permanent.

A contribution must be actually paid (not just accrued) to count in a given year. Accrue it in the accounts but pay it the following year, and it counts as a contribution in that later year for annual-allowance purposes.

Finally, the wholly-and-exclusively test means the contribution must be a genuine, funded business cost. A contribution the company cannot actually afford to pay is neither deductible nor effective, and can prompt questions from HMRC.

Next steps

If you run a PSC and are not currently using your annual allowance, an employer pension contribution is likely the biggest tax-efficient lever available to you. The carry-forward rule makes it flexible: under-contribute in lean years, catch up in strong ones, without a charge.

Model your position. Gather your annual statements, confirm your carry-forward, check whether the MPAA applies, and test whether the taper bites on your income. If you are facing a high-profit year or an exit, a large employer contribution can shelter meaningful profit from both corporation tax and the tax on extraction.

Work with a specialist contractor accountant to structure the contribution and get the Self Assessment reporting right. The savings are substantial and the rules detailed enough that professional input is worthwhile.
