HMRC Pension Top-Up Rules Change on 14 July 2026

If you save into a workplace pension and assume the tax side sorts itself out automatically, this quiet rule change is worth your attention. A new Statutory Instrument on legislation.gov.uk, the Registered Pension Schemes (Net Pay Arrangements) Regulations 2026, was made on 22 June 2026, laid before the House of Commons on 23 June 2026, and comes into force on 14 July 2026. The short version is simple. HMRC is widening top-up payments for some people in net pay pension schemes, because some savers were still getting less tax relief than they would have received in a relief at source scheme.

To see why that matters, we need one plain-English point. In a net pay arrangement, your pension contribution is taken before income tax is worked out. In a relief at source scheme, the contribution is paid from income after tax and the pension provider claims basic-rate tax relief back from HMRC. Both methods are meant to support retirement saving, but they do not always produce the same result. When that happens, two people can pay the same pension contribution and still end up with different levels of tax help. That is the fairness gap these Regulations are trying to narrow.

This sits inside section 193A of the Finance Act 2004, a provision added in 2023 to deal with an unfairness in net pay schemes. Until now, HMRC only had to make direct top-up payments where a person’s total taxable income was below the personal allowance. That helped some low earners, but the explanatory note says it did not catch everyone who lost out. Some people earned above the personal allowance and were still worse off than they would have been under relief at source. Being a taxpayer, in other words, did not always mean the system had treated you equally.

The legal change is quite tidy once you strip away the wording. The legislation rewrites section 193A so the test is no longer just whether someone had no income tax liability. Even the heading changes, from “relief where no income tax liability” to “disparity with relief at source”. From 14 July 2026, HMRC must compare the relief a person actually got under section 193, which covers net pay arrangements, with the amount they would hypothetically have received under section 192, which covers relief at source. Where there is a difference, HMRC must arrange to pay that difference to the individual, so far as reasonably practicable.

That comparison is technical because the law has to be exact. The revised section tells HMRC to look beyond the final tax bill and to account for cases where other tax reductions could hide the size of the pension relief someone missed. The text specifically refers to married couples’ and civil partners’ tax reductions, community investment tax relief, and the adjustments that would have applied under relief at source for Scottish or Welsh income tax rates. **What this means in practice:** HMRC is being asked to do a fuller like-for-like check. The question is not simply whether you paid tax, but whether your pension tax relief came out smaller because your scheme used net pay rather than relief at source.

The Regulations also add a recovery rule. If HMRC pays someone an amount that should not have been paid, it can assess and recover that money as though it were income tax due for the relevant tax year. That may sound severe, but it is really an administrative safeguard. It tells us these top-up payments are part of the tax system, with the usual checks attached, rather than a one-off extra that sits outside normal HMRC rules.

**What it means for you:** this is mainly a change to HMRC’s duty to make the payment, so most savers will not be rushing to complete a new form on day one. The more useful question is whether your workplace pension uses a net pay arrangement and whether you may have received less relief than a similar saver in a relief at source scheme. If you are unsure, your payslip, pension paperwork, payroll team or scheme administrator should be able to tell you which method your scheme uses. For teachers, public sector workers and anyone else in occupational pension schemes, that small bit of wording can make a real difference to what reaches your pension pot or your pocket.

The explanatory note says no Tax Information and Impact Note was prepared because the measure does not make a substantive change to tax policy. That is worth pausing on. The Treasury is not announcing a brand-new pension giveaway here; it is trying to make an existing promise of fairer treatment work more properly. So this may look like a niche legal amendment, but it speaks to a bigger lesson. Pension tax relief is not only about headline rates and big Budget speeches. Sometimes the most important change is a fix to the plumbing, because small design gaps can cost real savers real money.
