The Higher-Rate Pension Relief Claim You Might Not Have

I was three screens into HMRC's higher-rate pension relief claim before I worked out I didn't have a claim to make.

Every few months a post does the rounds telling higher-rate taxpayers they're owed free money on their pension.

"Claim your extra 20%." "Backdate it four years." I've seen enough of them to have half-believed I was one of the people missing out.

I wasn't. And the reason took a payslip and a deleted form to work out.

What the posts don't say

The advice isn't wrong exactly. It's aimed at a different kind of pension arrangement to the one a lot of us have through work. There are three ways a workplace or private contribution can be handled, and only one of them leaves you with anything to claim.

With relief at source, typically a personal pension or SIPP, you pay in from your take-home pay and the provider claims 20% back from HMRC and adds it to the pot. If you pay tax at 40% or 45%, that 20% isn't enough, and HMRC owes you the difference. You claim it through self-assessment or by writing to them, and you can backdate it four years. Gov.uk sets this out, including the backdating window.

With a net pay arrangement, the contribution comes out of your gross pay before income tax is worked out, so you get full relief at your marginal rate automatically, in the same payslip. Nothing to claim.

And with salary sacrifice, you give up part of your salary and your employer pays it into the pension instead. You get full income tax relief automatically, the same as net pay, and because the sacrificed pay never counts for National Insurance either, you save NI on top of the tax. Again, nothing to claim, and slightly better value than the other two.

The posts doing the rounds are about the first of those three. The other two relieve you in full as you go, so there's nothing sitting on the table. They rarely mention the distinction, because their target reader is the relief-at-source one.

Checking my own payslip

I went back to a payslip from before I retired. My workplace pension isn't relief at source. It's salary sacrifice, and the payslip shows it plainly once you know what you're looking at. My contribution comes off before the taxable pay figure is worked out, and the giveaway is in the pension balances: my employee pension contribution shows as zero, while the employer figure rises by the amount I'd sacrificed. That's the fingerprint of salary sacrifice. My contribution has been converted into an employer one. I'd also paid additional voluntary contributions through the same scheme in my last year, and they work the same way. Relieved in full, nothing outstanding.

The form gave it away

I started the HMRC online claim anyway, out of curiosity. It asks you to upload evidence, and one of the accepted documents is proof that you received 20% relief at source from your employer. That option only makes sense if the form expects some workplace schemes to work that way and some not to. I couldn't produce it, because that kind of relief doesn't exist in my scheme. I deleted the form before submitting anything.

Which camp are you probably in?

You can't read this off perfectly from someone's job, because the same employer can run different arrangements for different staff, and schemes change providers over time. But there are patterns.

You're most likely to have an actual claim if you pay into a personal pension or SIPP yourself, outside any workplace scheme. That's always relief at source, so the self-employed, contractors, and anyone topping up their own private pot are the clearest case. Some employees auto-enrolled through a master trust or group personal pension are in the same boat, which is common at smaller and medium employers. NEST, the big auto-enrolment provider, is one example that operates relief at source.

You're more likely to be relieved in full already, with nothing to claim, if you're in the public sector, the NHS, teachers, civil service, local government and the armed forces, where net pay arrangements are the norm. Larger private employers running their own occupational scheme often use net pay too. And salary sacrifice, my own case, is increasingly common across medium and large private firms, because the employer saves National Insurance as well. If your scheme is badged "SMART" or something similar, that's usually the sign.

One thing holds with no exceptions: none of this matters unless you pay tax at 40% or 45%. A basic-rate taxpayer in a relief-at-source scheme already gets the right amount through the automatic 20%, and has nothing to claim. The unclaimed money only exists for higher and additional-rate payers who are in relief-at-source schemes.

What's actually worth checking

If you're in a workplace pension, look at your own payslip. If your pension contribution comes off before your taxable pay is calculated, whether through a net pay arrangement or salary sacrifice, you're already getting full relief and there's no claim to make. If your taxable pay is your full gross figure and the pension is taken separately from what's left, relief at source is more likely, and it's worth working out whether you've claimed what you're owed.

If you can't tell which one yours is, your scheme booklet, or a quick question to HR or your provider, will settle it.

The people telling you to claim aren't lying. They're just not telling you the bit that decides whether it applies to you.
