For most LGPS members, the pension they build up each year sits comfortably within the standard annual allowance — the amount by which your total pension savings can grow, tax-free, in a single tax year. But for members who receive a large pay rise, get promoted into a considerably higher-paid role, or buy extra pension in one go, the LGPS's own particular way of measuring "growth" against the annual allowance can produce a surprisingly large figure, even though nothing about their own personal contribution actually changed. This guide explains how the annual allowance calculation works for LGPS members, why a pay rise can trigger it, and what to do if you receive a Pension Savings Statement telling you that you've exceeded it.
How defined benefit pension growth is measured against the allowance
Unlike a defined contribution pension, where the annual allowance simply measures the money paid in during the year, a defined benefit scheme like the LGPS measures allowance usage very differently. What's tested against your £60,000 standard annual allowance is the increase in the value of your annual LGPS pension entitlement over the tax year — not the amount you or your employer actually paid in contributions. For a full explanation of how the standard allowance works across all pension types, see our guide to the annual allowance explained.
In practice, this is worked out using a formula set by HMRC: broadly, your opening pension entitlement at the start of the tax year is increased in line with inflation (CPI), and then compared with your closing pension entitlement at the end of the tax year. The difference between the revalued opening value and the closing value is multiplied by a factor of 16 to convert it from an annual pension figure into a notional capital value, and it's this capital value that counts as your "pension input amount" for annual allowance purposes.
Why a pay rise can catch LGPS members by surprise
Because the calculation is based on the growth in the value of your pension entitlement, and that value is directly driven by your pensionable pay, a significant pay increase in a single tax year feeds straight into a bigger notional pension input amount for that year — even though you haven't personally paid a penny more in contributions than the normal rate for your new salary band. This is the single biggest reason LGPS members are caught out by the annual allowance: it isn't really about how much you're saving, it's about how much your future pension promise has grown in value.
Take an officer who receives a substantial promotion partway through the year, moving their pensionable pay up considerably. Even though their percentage contribution rate hasn't changed, the pension they're entitled to for every year of past service effectively gets "repriced" at the new, higher salary level when calculating their closing pension value for that year, which can produce a pension input amount well above the norm for that single tax year, purely as an artefact of the pay rise itself rather than any change in actual saving behaviour.
Worked example: a pay rise triggering LGPS annual allowance growth
Who's most likely to be affected
In practice, it tends to be a fairly specific group of LGPS members who need to pay close attention to this: senior local government officers and directors who receive significant salary increases on promotion; long-serving members, because the repricing effect of a pay rise is amplified by more years of past service being revalued at the new salary; and members who choose to buy additional pension in a single lump sum payment, since that purchase itself adds directly to the pension input amount for the year it's bought. Someone early in their career on a modest salary, with only gradual, inflation-linked pay rises, is very unlikely to come anywhere near the standard allowance from LGPS growth alone.
The tapered annual allowance and high earners
Very high-earning LGPS members — typically senior officers and directors with total taxable income (including the value of pension growth itself) above certain thresholds — may also be subject to the tapered annual allowance, which reduces the standard £60,000 allowance by £1 for every £2 of adjusted income above the relevant threshold, down to a minimum tapered allowance. This can compound the effect of a pay rise: not only does the rise increase the LGPS pension input amount itself, it can also increase adjusted income enough to reduce the available allowance at the same time, creating a double squeeze for the small number of members affected.
Carry forward — using unused allowance from previous years
One relief valve that catches out fewer LGPS members than it should is carry forward. If your pension input amount in the current tax year exceeds £60,000, you may be able to offset the excess using any unused annual allowance from the three previous tax years, provided you were a member of a registered pension scheme in those years. Because most LGPS members use only a small fraction of the standard allowance in a typical year, there's often a reasonable amount of unused allowance sitting from earlier years that can absorb a one-off spike caused by a pay rise or an added years purchase, potentially avoiding a tax charge altogether. Carry forward doesn't happen automatically — you need to work out whether it applies, usually with the help of the pension input amounts shown on Pension Savings Statements for the relevant years, so it's worth checking rather than assuming a large one-off growth figure automatically means a tax charge is due.
Scheme Pays — how the LGPS can settle the tax charge for you
If your total pension savings across all your registered pension schemes exceed the annual allowance in a tax year, the excess is subject to an annual allowance charge, effectively clawing back the tax relief you received on the excess growth. Rather than needing to find a potentially large tax bill from your take-home pay, the LGPS (like most public sector schemes) offers a facility called Scheme Pays.
Under Scheme Pays, the scheme itself pays some or all of the annual allowance charge directly to HMRC on your behalf, and in exchange, your future LGPS pension is permanently and actuarially reduced by an amount that reflects the value of the charge paid. This avoids you needing to find a large cash sum immediately, spreading the cost instead across your future pension in payment. Mandatory Scheme Pays is available where your charge for LGPS growth alone exceeds £2,000 and your total pension savings growth exceeds the standard allowance; voluntary arrangements may be available in some other circumstances too, so it's worth asking your pension fund administering authority directly about your options if you're affected.
Where to check — your Pension Savings Statement
You don't need to work out any of this yourself. If your pension growth in the LGPS (combined with any other registered pension schemes) exceeds the standard annual allowance in a tax year, your LGPS administering authority is required to automatically issue you a Pension Savings Statement, usually by 6 October following the end of the relevant tax year. This statement sets out your pension input amount for that year, and it's the starting point for working out whether you owe an annual allowance charge and whether Scheme Pays might be worth using. If you think you might be affected — for example, following a large pay rise — but haven't received a statement, it's worth contacting your fund administrator directly rather than assuming you're automatically in the clear, since statements are based on scheme records and can occasionally be delayed.

How the pension input period lines up with the tax year
For all defined benefit schemes since April 2016, the period used to measure annual allowance growth — the pension input period — has been aligned with the standard UK tax year, running from 6 April to the following 5 April. This means your LGPS pension input amount for annual allowance purposes always covers the same twelve months as your income tax year, which makes it easier to line up alongside other tax considerations, such as your adjusted income for tapered annual allowance purposes, since both are calculated over the same period.
Before this alignment took effect, different schemes could use different input periods, which occasionally made it harder for members of more than one scheme to work out their combined position for a single tax year. Since the alignment, if you're a member of the LGPS alongside a personal pension or another workplace scheme, all of your pension input amounts for a given tax year can be added together directly without needing to adjust for mismatched periods.
If you're a member of more than one pension scheme
The £60,000 standard annual allowance applies across all of your registered pension schemes combined, not separately to each one. If you're an LGPS member who also pays into a personal pension, a workplace pension with a previous employer, or a scheme from an earlier public sector role, you need to add together the growth in all of them for the tax year to see whether you've exceeded the allowance overall — even if no single scheme's growth alone would have triggered it.
This is a particular risk for people who've moved between the public and private sectors, or between different public sector employers, during a single tax year, since it's easy to focus on the LGPS Pension Savings Statement in isolation and overlook growth elsewhere. If you have benefits in more than one scheme, it's worth gathering the pension input amount figures from each provider for the relevant tax year before concluding whether an annual allowance charge applies, rather than assuming the LGPS figure alone tells the whole story.
Keeping records to avoid surprises
Because LGPS annual allowance calculations depend on pay figures and revaluation factors that can be hard to reconstruct after the fact, it's worth keeping your own simple record of significant pay changes — promotions, large bonuses, or added years purchases — alongside any Pension Savings Statements you receive. This makes it much easier to sense-check a statement when it arrives, and to spot quickly if a particular year's figure looks unusually high because of a specific, identifiable event like a promotion, rather than needing to query it with your administering authority from scratch.
If you're approaching a period where you expect a significant pay change — for example, a known promotion or a planned large pension purchase — it can also be worth asking your LGPS fund in advance for an estimate of how this might affect your annual allowance position for that tax year, so that any potential Scheme Pays decision or use of carry forward can be planned for rather than discovered only after the statement arrives.
What to do if you think you'll be affected next year
If you know a significant pay rise, promotion, or added years purchase is coming up, it's worth thinking about your annual allowance position before the tax year in question ends, rather than waiting for a Pension Savings Statement to tell you after the fact. Some members choose to ask their LGPS fund for an estimate of the likely pension input amount for the year in advance, particularly where a large one-off change (such as buying a significant amount of additional pension) is being considered, so the potential tax impact can be weighed up as part of the decision rather than discovered only once it's already happened.
Because carry forward can only be used against unused allowance from the three previous tax years, it's also worth keeping a rough sense of how much of your allowance you've used in recent years, since a member who has consistently used only a small fraction of the standard allowance is in a much stronger position to absorb a one-off spike than someone who has already used most of their allowance through other pension savings, such as a personal pension or a previous employer's scheme.
The bigger picture: annual allowance is about growth, not affordability
It's worth remembering that an annual allowance charge doesn't mean you've done anything wrong, or that your pension saving was somehow excessive in ordinary terms — it simply means the value of your pension promise grew by more than the tax rules allow to receive tax relief in a single year, often for reasons entirely outside your control, such as your employer awarding you a well-deserved promotion. Many members who receive a Pension Savings Statement showing they've exceeded the allowance are surprised, precisely because the trigger is a change in salary rather than a deliberate decision to save more.
Understanding this distinction can make the whole process feel less alarming: it's a technical measurement of pension growth for tax purposes, not a judgement on your financial decisions, and mechanisms like Scheme Pays and carry forward exist specifically to make sure a one-off, pay-driven spike doesn't create an unmanageable cash-flow problem for members affected by it.
