How does the tapered annual allowance work for high earners?
The tapered annual allowance cuts the £60,000 pension annual allowance by £1 for every £2 of adjusted income above £260,000, to a floor of £10,000. It only bites if threshold income also exceeds £200,000, and that second test is the one worth planning around — because pension contributions themselves reduce it.
- The taper: £1 of allowance lost for every £2 of adjusted income above £260,000, floor £10,000.
- The gate: no taper at all unless threshold income also exceeds £200,000.
- The lever: personal contributions reduce threshold income; employer contributions do not.
- The charge: excess contributions are taxed at your marginal rate, cancelling the relief.
Tom Whitfield, my closest friend from my London years and now in Manchester, hit this the year his employer restructured its bonus. His salary had not changed much, but a deferred award vesting in the same tax year pushed his adjusted income to £284,000 — and the letter telling him his annual allowance was £48,000 arrived after he had already contributed £60,000.
01 Two income tests, not one
The taper only applies if you fail both tests, and this is where most of the confusion in this area comes from. Threshold income is broadly your taxable income less your own pension contributions. Adjusted income is broadly your taxable income plus all pension contributions, including your employer's. The taper starts only when threshold income exceeds £200,000 and adjusted income exceeds £260,000.
The two definitions pull in opposite directions on purpose. Adjusted income adds contributions back so that someone cannot escape the taper by sacrificing salary into a pension. Threshold income subtracts them so that someone whose income is high only because of employer contributions is not caught. The result is a genuine gate: a director on a £150,000 salary with £150,000 of employer contributions has adjusted income of £300,000 and threshold income of £150,000, and is not tapered at all.
Getting the two figures right is most of the work. They are not the numbers on a P60, and they include investment income, rental profit, and any bonus that falls into the year.
02 What the taper costs when it applies
Every £2 of adjusted income above £260,000 removes £1 of annual allowance, so £320,000 of adjusted income leaves £30,000 and £360,000 or more leaves the £10,000 floor. Contributions above whatever allowance survives attract an annual allowance charge at your marginal rate, which for this population is 45% plus, in Scotland, more.
The charge is not a penalty on top of tax — it removes the relief the contribution attracted. That makes an over-contribution close to neutral in cash terms and negative in flexibility, because the money is now locked in a pension having received no net advantage. Which is precisely the outcome to avoid rather than to accept.
Where the charge exceeds £2,000 and the excess relates to a single scheme, the scheme can be asked to pay it in exchange for a reduction in benefits. That converts a cash bill into a smaller pension, and for a defined benefit member it is often the only practical route.
Shows: your annual allowance after the taper, from your threshold and adjusted income. Ignores: carry-forward from earlier years, defined benefit pension input amounts, the money purchase annual allowance, and Scottish rates on the charge.
On the defaults above, the worked example shows £40,000. Both tests failed, so the allowance is cut by £20,000 to £40,000.

03 The lever: personal contributions cut threshold income
A personal contribution reduces threshold income pound for pound, and threshold income is the gate. Someone with threshold income of £205,000 and adjusted income of £280,000 is tapered to £50,000; a personal contribution of £5,000 brings threshold income to £200,000, and the taper falls away entirely, restoring the full £60,000. The contribution bought back £10,000 of allowance at a cost of £5,000 of money that was going into a pension anyway.
This only works near the threshold, and it only works with personal contributions — a salary sacrifice into an employer contribution reduces taxable pay but is added back into adjusted income, and gift aid donations reduce threshold income too. Above about £210,000 of threshold income the arithmetic stops paying, because the contribution needed to reach £200,000 exceeds what it recovers.
It is also a timing question. Bonuses, share vestings and property disposals are what push people over, and where any of those can be moved across a tax year boundary the taper can be avoided rather than mitigated. Sacrificing salary does not help with adjusted income but does help with the tax on it.
04 Carry-forward still works, with a catch
Unused annual allowance from the previous three tax years can be carried forward against a tapered allowance, and for high earners this is usually where the headroom is. The catch is that the carried-forward amount is the tapered allowance for each of those years, not £60,000 — so someone tapered for four consecutive years has far less available than the arithmetic suggests.
You also have to have been a member of a registered pension scheme in each year you carry forward from, even if you contributed nothing. Membership without contributions preserves the allowance; no membership loses it. That single condition is the reason a self-employed year with no scheme is worth opening a nominal pension in.
05 The order to do this in
Establish the two income figures before the tax year ends, not after. Adjusted and threshold income are only knowable once bonuses and investment income are settled, and the useful moves — a personal contribution, a gift aid donation, deferring a disposal — all have to happen inside the year.
Then check carry-forward for the three preceding years, at their tapered levels. Then contribute up to whatever the two together allow. Doing it in the other order, contributing first and calculating in the summer when the pension savings statement arrives, is how Tom ended up with an allowance charge on money he had already committed.
The taper is the only pension rule I know that punishes you for a number you cannot see until the year is over. Everyone I have watched get caught was caught by timing — a bonus, a vesting, a property sale — not by their salary. So the move is not clever structuring, it is calendar discipline: work out both income figures in January, not July, and if threshold income is sitting just over £200,000, a personal contribution to push it under is the highest-return five thousand pounds you will spend that year. Above about £210,000 that trick stops working, and then it is carry-forward or nothing.
FAQ
What is the difference between threshold and adjusted income?
Threshold income is broadly your taxable income minus your own pension contributions; adjusted income is broadly your taxable income plus all pension contributions including your employer's. The taper needs threshold income above £200,000 and adjusted income above £260,000 — failing only one leaves the full allowance.
Can salary sacrifice get me under the taper?
Not by itself. Sacrificed salary becomes an employer contribution, which is added back into adjusted income, so the adjusted income test is unchanged. It does reduce threshold income, which can matter if that is the test you are failing marginally.
What happens if I contribute more than my tapered allowance?
An annual allowance charge applies at your marginal rate on the excess, which removes the tax relief the contribution attracted. Where the charge exceeds £2,000 and relates to one scheme, you can ask the scheme to pay it in exchange for reduced benefits.
Does carry-forward still work if I am tapered?
Yes, but the amounts carried forward are each year's tapered allowance, not £60,000. You also need to have been a member of a registered pension scheme in each year you carry forward from, even if you paid nothing into it that year.
