Pension Allowance Calculator UK 2026/27

A UK pension allowance calculator helps answer a specific planning question: after adding personal contributions, employer contributions and defined-benefit pension growth, how much pension input may remain for 2026/27, and could carry forward, tapering or the Money Purchase Annual Allowance change the result?

Use the Pension Allowance Calculator→ to model current-year pension input, unused allowance from earlier years, tapering and MPAA scenarios. This is a calculator-workflow guide. The existing Pension Annual Allowance guide explains the wider rules; this page focuses on entering the correct evidence, interpreting the waterfall and knowing which outputs still need provider or HMRC confirmation.

Key takeaways

What the calculator is actually estimating

The calculator creates a planning waterfall. It starts with a standard or entered Annual Allowance, adjusts it for a simplified taper or MPAA assumption, adds eligible unused allowance from earlier years, and compares the total available amount with the pension input entered for the current tax year. It may also show an illustrative excess or tax-charge estimate.

That output is not a provider statement. It does not independently verify:

• the pension input period for every scheme;
• the defined-benefit increase in promised benefits;
• contributions paid by an employer or another person;
• the correct threshold-income and adjusted-income figures for tapering;
• whether flexible access actually triggered MPAA;
• whether the previous three years’ membership condition is met;
• whether carry forward has already been used;
• tax relief on personal contributions; or
• whether a pension scheme can or will use Scheme Pays.

The right interpretation is “available under the entered assumptions”. Before making a large contribution, request statements from every provider and reconcile the tax year, contribution date, pension input amount and carry-forward history.

Step 1: identify every pension arrangement

Annual Allowance is not a per-pension limit. GOV.UK says it applies to all private pensions if you have more than one. For defined-contribution arrangements, the total input generally includes contributions paid by you, your employer or another person. For defined-benefit arrangements, the input is based on the increase in promised benefits under the statutory test, not simply the amount shown as a monthly employee deduction.

Create an inventory before entering the calculator:

Do not enter only the amount you personally paid if the employer also contributed. Do not use the fund’s investment growth as the defined-contribution input. Conversely, do not use the contribution total alone for a defined-benefit scheme.

Step 2: choose the tax year and input timing

The UK tax year runs from 6 April to 5 April. A contribution paid shortly before or after 5 April may fall into a different tax year, and a payroll record can show a different date from the date the employee expected. Enter the tax year shown on the provider statement.

For 2026/27, GOV.UK states that the standard Annual Allowance is £60,000. That is the starting point, not a guarantee that every saver can use £60,000 for personal tax relief or that the amount is available after tapering or MPAA. Keep the calculator’s tax-year label visible in any saved scenario so a future change in rates or rules is not confused with the current estimate.

If the calculator uses monthly inputs, reconcile the monthly total to the provider’s tax-year total. An employer may pay contributions after payroll closes, and a defined-benefit scheme may issue its statement later. The statement is more authoritative than an even-monthly assumption.

Step 3: test carry forward separately

GOV.UK says you may be able to carry forward unused Annual Allowance from the previous three tax years. HMRC’s guidance explains that the current-year allowance is tested with the relevant previous years, subject to conditions including pension scheme membership. The available carry forward is not simply “three times £60,000”: each year has its own allowance, pension input and unused amount.

Use a year-by-year table:

Replace the placeholders with actual statements. If the current-year input does not exceed the current-year allowance, carry forward may not be needed at all. If there is an excess, use the oldest available amount in accordance with the statutory calculation rather than choosing the most convenient year.

Carry forward increases Annual Allowance capacity. It does not automatically increase the amount of personal contribution that receives tax relief. Relevant UK earnings and the contribution method remain separate checks.

Step 4: check whether tapering applies

For 2026/27, GOV.UK states that tapered Annual Allowance applies if both threshold income is over £200,000 and adjusted income is over £260,000. The calculator may use a simplified salary or income proxy, but the statutory definitions can include more than basic salary and can involve pension contributions, taxable income and other adjustments.

Do not enter a headline salary and assume the result is the official adjusted-income test. Gather:

• employment and self-employment income;
• taxable benefits, savings and dividend income where relevant;
• pension contributions by the employee and employer;
• salary sacrifice changes;
• reliefs and deductions included in the statutory tests; and
• any other amount required by HMRC’s taper guidance.

If the result is near a threshold, run a lower and higher scenario and request a professional calculation. A small change in an input can affect the available allowance, while an inaccurate proxy can create false confidence that a contribution is within the limit.

Step 5: identify a possible MPAA trigger

The Money Purchase Annual Allowance can apply after certain forms of flexible access to a defined-contribution pension. GOV.UK lists examples such as taking cash or a short-term annuity from a flexi-access drawdown fund or taking an uncrystallised funds pension lump sum. The 2026/27 MPAA is £10,000 according to the published pension rates.

The trigger is not the same as simply reaching a pension access age or taking every kind of tax-free cash. Check what was actually taken, when it was taken and what notice the provider issued. If MPAA applies, the money-purchase input is tested against that lower amount, while the wider Annual Allowance calculation may still involve an alternative allowance for other pension input.

In the calculator, treat “MPAA triggered” as a fact to verify, not a casual toggle. Keep the provider’s event statement and the date of flexible access. Do not make a large contribution based only on the default “not triggered” state if you have already accessed a pension flexibly.

Step 6: keep Annual Allowance separate from tax relief

There are two different ceilings:

GOV.UK says tax relief on private pension contributions can be available up to 100% of annual earnings, with a £3,600 gross basic amount relevant in some low- or no-earnings cases. The provider may claim 20% relief under relief at source, while additional relief can require a Self Assessment claim depending on the taxpayer and scheme.

An employer contribution can count towards Annual Allowance even though it is not a personal relief-at-source payment. A salary-sacrifice contribution can change the payroll and tax position while still counting as pension input. The calculator should show these paths as separate inputs rather than merging them into one “contribution” number.

Step 7: interpret an excess and Scheme Pays carefully

If entered pension input exceeds available Annual Allowance after carry forward, the calculator may display an illustrative excess or charge. GOV.UK says the excess can be reported through the pension savings tax charges section of Self Assessment, even if a pension provider pays all or part of the charge. The provider’s statement and the relevant return determine the actual reporting.

Scheme Pays is not a universal automatic solution. The scheme rules, type of charge, amount, election deadline and provider agreement matter. A charge paid from the pension can reduce future retirement value. Before selecting a Scheme Pays scenario, identify whether the scheme offers mandatory or voluntary Scheme Pays and obtain the required notice.

Do not simply reduce a contribution because the calculator shows an excess. Compare the cost of the charge, the value of carry forward, employer matching, the retirement objective, cash flow and the provider’s available options. A tax charge can be manageable in one situation and material in another.

Run four useful scenarios

The useful output is not just “remaining allowance”. Compare the remaining allowance, tax-relief capacity, employer match, immediate net-pay effect, possible charge, retirement value and access restrictions. A contribution that fits the allowance can still be unaffordable or unsuitable; a contribution that exceeds the current allowance may be defensible only after verified carry forward and specialist review.

Records to keep before relying on the result

Keep the calculator inputs with the provider evidence. For each scheme, store the Annual Allowance statement, contribution dates, employer contribution record, defined-benefit input, flexible-access statement and any previous-year carry-forward calculation. Keep payslips and salary-sacrifice agreements where they explain the contribution route.

If a provider has not issued a statement, use a clearly marked estimate and do not present it as confirmed unused allowance. If you have multiple schemes, ask each provider for the relevant statement. If a previous employer’s pension is defined benefit, the calculation may require information that is not visible on a current payslip.
