Annual allowance and the NHS pension

Why a scheme you can't overpay into produces tax bills, and who it actually hits.

The annual allowance limits how much pension you can build in a year before a tax charge applies. It was designed with pots of money in mind, where the amount going in is a number you choose.

The NHS pension has no pot. What gets tested instead is how much the value of your promised benefits grew over the year, which is a figure you don't control, don't choose, and often can't predict.

That mismatch is why a consultant can get a five-figure tax bill in a year they did nothing differently.

What's actually measured

Your pension input amount is, broadly, the value of your benefits at the end of the year minus their value at the start, with the opening figure uprated for inflation first.

Benefits are valued by multiplying the annual pension by 16, and adding any automatic lump sum.

That multiplier is worth sitting with. An increase of £1,000 a year in your promised pension counts as £16,000 of pension growth. A modest-sounding improvement produces a large number in the calculation.

Your own contributions and your employer's are irrelevant to this. It doesn't matter that you paid the same percentage you always pay.

Why it hits consultants

Three things combine.

Final salary linking. If you have 1995 or 2008 Section benefits, a pay rise doesn't just improve this year, it revalues every year of service you have ever accrued. A consultant with twenty years' service getting a significant rise can see their promised pension jump substantially, and that jump is multiplied by 16.

The events that trigger it. Promotion to consultant. A clinical excellence or local award. Moving from part-time to full-time. Taking on extra sessions or a management role. A pay award outpacing the inflation figure used to uprate the opening value.

The tapered annual allowance. Above certain income levels the £60,000 allowance reduces, down to a floor of £10,000. Consultants with private practice income, on-call supplements, awards or additional NHS sessions can find themselves tapered without thinking of themselves as very high earners.

The taper turns on two separate measures, threshold income and adjusted income, and adjusted income includes your pension growth. That produces the circularity that catches people out: the pension growth creating the problem also shrinks the allowance available to absorb it.

Who it doesn't hit

Most members, and that's worth saying plainly, because the coverage is alarming and the reality is narrower.

If you're in the 2015 Scheme only, on a steady salary, with no unusual pay events, your pension input amount is unlikely to trouble a £60,000 allowance. Career average accrual doesn't produce the spikes final salary linking does.

The people who need to check are those with legacy service, a significant pay increase, or income high enough for the taper to bite.

Carry forward

Unused allowance from the previous three tax years can be carried forward, and it absorbs a great many charges before they ever become payable.

Two NHS-specific complications:

Your pension savings statement won't tell you. NHSBSA produces statements against the standard allowance. If you're tapered, your actual allowance in earlier years was lower than the statement assumes, and your real carry forward is less than it appears.

Excess in an intervening year eats earlier unused allowance first. A year where you exceeded the allowance consumes the oldest available headroom before the current year gets to it. Working that out by hand across four years is where most manual attempts go wrong.

The NHS Annual Allowance Check does the waterfall properly, deriving prior year tapered allowances rather than taking statement figures at face value.

If there is a charge

You have two ways to pay it: from your own money, or by asking the scheme to pay it in exchange for a permanent reduction in your pension. See Scheme pays.

There are also things that change the position for future years, including pension contributions elsewhere, salary sacrifice arrangements and the timing of awards. None is universally right, and they trade against each other, since reducing your income to restore your allowance also reduces your pension and your take-home. The calculator lets you model each without ranking them, because the right answer depends on what you're trying to protect.

What to do

Get your figures. Getting your pension figures explains what to ask for and when it arrives.

Run them through the NHS Annual Allowance Check.

If there's a charge, or if you're close to one, this is an area where advice earns its fee. The interaction of the taper, carry forward, the McCloud choice and scheme pays is genuinely difficult and the mistakes are expensive.
