How to Use Annual Allowance Carry Forward for Pension Contributions

The annual allowance (AA) caps how much can be contributed to your pension each tax year with tax relief. In 2026/27 the standard AA is £60,000. For most people, that is already generous — but business owners, directors, and professionals who have had years with low pension contributions (or no pension at all) often want to make a large one-off payment to catch up. Carry forward makes this possible.

Used correctly, carry forward can allow contributions of up to £240,000 in a single tax year, delivering income tax relief at your marginal rate on every pound.

What Is Annual Allowance Carry Forward?

Carry forward allows you to use unused annual allowance from the three previous tax years. If you had unused allowance in those years — because your contributions were below the AA limit — you can add that unused amount on top of the current year's AA.

The current year's AA must be used first. Only then can you layer in carry-forward amounts, working from the oldest year forward.

Example calculation (illustrating the rule with historical figures):

Tax Year	Annual Allowance	Contributions Made	Unused AA
2023/24	£60,000	£5,000	£55,000
2024/25	£60,000	£10,000	£50,000
2025/26	£60,000	£15,000	£45,000
2026/27	£60,000	—	—

In 2026/27, this individual can contribute up to £60,000 (current year) plus £55,000 + £50,000 + £45,000 (carried forward) = £210,000 in total, provided their earnings are sufficient to support the contribution.

The unused amount from each year is the allowance that applied in that year, not the current year's figure. In 2026/27 the annual allowance has been £60,000 in each of the three lookback years, so the maximum possible carry-forward total (if all three prior years were entirely unused) is £240,000.

The Earnings Requirement

There is a critical condition: you cannot contribute more to a pension than you earn in the relevant tax year. "Earnings" for this purpose means UK relevant UK earnings — broadly, employment income, self-employment profit, and certain other earned income.

Investment income, rental income, and pension income do not count. So if you have £500,000 of dividends and £20,000 of salary, you can only contribute up to £20,000 from your own pocket (though employer contributions are subject to different rules and can go up to the full AA limit regardless of earnings).

For business owners paying themselves largely through dividends, this earnings cap is often the binding constraint — not the AA itself.

Pension Scheme Membership Requirement

You can only carry forward unused allowance from a tax year in which you were a member of a registered pension scheme. This includes any scheme: an occupational scheme, a stakeholder pension, a personal pension, a SIPP. You do not need to have made contributions in that year — simply being a member is sufficient.

If you only opened a pension recently and were not a member in 2021/22, you cannot carry forward from that year. The allowance from years before your scheme membership simply does not exist for carry-forward purposes.

This is one reason to establish at least a nominal pension arrangement early in your career, even if contributions are minimal — the membership clock starts ticking.

The Order of Carry Forward

HMRC requires you to apply carry forward in a specific sequence:

1. Use the current year's annual allowance first.
2. Then carry forward from the earliest of the three eligible years.
3. Then from the next year.
4. Then from the most recent prior year.

This matters because years drop off the three-year window each April. For example, if you have significant unused allowance from 2023/24, you must use it (or lose it) by 5 April 2027.

The Tapered Annual Allowance

High earners face a reduced AA. If your "adjusted income" (broadly, total income including employer pension contributions) exceeds £260,000, your AA is tapered by £1 for every £2 of adjusted income above that threshold, to a minimum AA of £10,000.

Carry forward still applies to tapered allowances — but the calculation becomes more complex, as your tapered AA may differ in each of the three lookback years (since the threshold and taper rules have changed over time). Professional advice is strongly recommended before attempting carry forward if you may be subject to the taper.

Who Benefits Most?

Business owners and directors are the primary beneficiaries. A company director who has been drawing minimal salary and large dividends for several years may have significant unused AA. By raising their salary in the carry-forward year, and having the company make employer contributions, they can potentially clear the entire three-year backlog in a single year.

Employer contributions are corporation tax deductible (subject to the "wholly and exclusively" test) and do not attract National Insurance for employer or employee. The combined tax benefit can be substantial.

Professionals with lumpy income — partners in law or accountancy firms, consultants, surgeons in private practice — often have years of lower earnings followed by peaks. Carry forward allows them to make a large pension contribution in a high-income year, securing relief at 45% on amounts that would otherwise be taxed heavily.

Those approaching retirement who have built up assets outside a pension may wish to shift wealth into the pension environment (for IHT efficiency and tax-free growth) using carry forward to make a large last contribution before drawing benefits.

A Worked Example: Director Making Full Use of Carry Forward

Sarah is a company director. She pays herself £50,000 salary and has unused AA as follows:

• 2023/24: £55,000 unused
• 2024/25: £50,000 unused
• 2025/26: £45,000 unused

In 2026/27, her company makes an employer contribution of £210,000 into her SIPP (using carry forward to cover the full amount). The contribution is:

• Fully within the annual allowance when carry forward is applied
• Corporation tax deductible for the company (saving approximately £42,500 at the 25% main rate, or £32,300 at the 19% small-profits rate for companies with profits under £50,000)
• Tax-free inside the pension wrapper
• Not subject to income tax or NI for Sarah

The pension fund grows free of income tax and CGT. Currently, undrawn pension funds pass outside the estate for IHT purposes — but from 6 April 2027 (Finance Act 2026), unused pension funds and death benefits will be brought within the IHT estate. This is a significant planning consideration: the pension IHT shelter that made carry forward particularly attractive for estate planning purposes will be substantially reduced from that date. Income tax on drawdown by beneficiaries continues to apply after age 75 death as before.

Interaction with the Money Purchase Annual Allowance

If you have already flexibly accessed pension benefits — drawing income from a drawdown fund, for example — your AA for money purchase (defined contribution) contributions reduces to the Money Purchase Annual Allowance (MPAA), which is £10,000. Carry forward cannot be used to increase the MPAA. This is a significant restriction.

If you intend to use carry forward in the future, avoid triggering flexible access until after you have made your large contribution.

Practical Steps Before Making a Large Contribution

1. Confirm pension scheme membership in each of the three prior years.
2. Gather evidence of contributions made in those years — your pension providers can confirm these.
3. Calculate the remaining unused allowance for each year, remembering which AA applied.
4. Ensure your earnings in the current year are sufficient to support the personal contribution.
5. Check whether you are subject to the taper, and calculate your tapered AA for each relevant year.
6. Keep records — HMRC may ask you to demonstrate the carry-forward calculation.

You do not need to notify HMRC in advance, but you do need to keep adequate records and report large pension contributions through self-assessment.

How Global Investments Can Help

Pension carry forward calculations sit at the intersection of tax planning, business structuring, and long-term wealth management. Getting them wrong — for example, triggering an annual allowance charge by exceeding the limit — results in a tax bill that largely negates the benefit.

Global Investments works with directors, business owners, and professionals to model carry-forward scenarios, coordinate with company accountants on employer contributions, and integrate pension planning with broader wealth strategy. If you have unused allowances you want to use before they expire, speak to our advisers well before the tax year end.
