What are the rules for paying into your spouse's pension?
Anyone under 75 can contribute £2,880 net to a pension and receive £720 of basic-rate relief, giving £3,600 gross — regardless of whether they have any earnings at all. For a household with one earner, that is the only route to building a pension in the non-earning partner's own name, and the relief is real money from HMRC.
- The amount: £2,880 net becomes £3,600 gross after basic-rate relief.
- The condition: under 75, and no earnings requirement at all.
- The purpose: a pension and eventually a personal allowance in the lower earner's own name.
- The reality: the contribution is a gift; the pension is theirs.
01 How the relief works
Contributions to a relief-at-source pension attract basic-rate relief whether or not the contributor pays tax. A payment of £2,880 has £720 added by HMRC, giving £3,600 in the pot, and no tax needs to have been paid for that to happen.
The limit for someone with no relevant earnings is £3,600 gross a year. Someone with earnings can contribute up to 100% of them instead, capped by the annual allowance, so the £3,600 floor matters specifically for non-earners.
The contribution can be funded by anyone — a spouse, a parent, a grandparent — but the relief and the pension belong to the person the contribution is made for.

02 Why it is worth more than the relief
The £720 a year of relief is useful and it is not the main benefit. The main benefit is that the non-earning partner ends up with a pension in their own name, and therefore with income to set against their own personal allowance in retirement.
Ten years of contributions is £36,000 gross plus growth, which drawn at £3,600 a year covers a decade of using an allowance that would otherwise be wasted. At the basic rate that is worth £720 a year of tax saved, every year, on top of the relief already received.
It also gives the lower-earning partner an asset of their own, which matters for survivorship and for the household's flexibility in ways a single large pension does not.
Shows: the pot built by the £3,600 route and the annual tax saving it eventually produces. Ignores: investment returns beyond the rate you enter, charges, and the State Pension.
On the defaults above, the worked example shows £60,167. Relief of £8,640 along the way, and a pot that can produce income against a personal allowance that would otherwise go unused.
03 The things to be clear about
The pension is theirs. It is their asset in a divorce, it forms part of their estate, and they decide what to do with it — including when and how to draw it. That is a real consequence and it should be understood rather than glossed over.
The contribution also has to be affordable from the household's actual surplus. £2,880 a year locked away until 57 is not the right destination for money that might be needed, and an ISA offers the same household benefit with access.
And keep contributing after the higher earner retires if the allowance is still there. The £3,600 route continues to age 75, and the years immediately before State Pension age are when the resulting income is most useful.
The £720 a year of relief for someone who paid no tax is the part that surprises people, and it is the smaller half of the argument. What you are really building is a pension in the lower earner's name, and therefore an income they can set against their own personal allowance in retirement — which is worth another £720 a year, every year, and which is otherwise simply wasted. Be clear that the pot is theirs. That is what makes it work, and it is the part worth saying out loud before the first payment.
FAQ
Can someone with no income get pension tax relief?
Yes. A contribution of £2,880 net attracts £720 of basic-rate relief and becomes £3,600 gross, regardless of whether the person has any earnings or has paid any tax.
Who does the pension belong to?
The person it is contributed for. It is their asset in a divorce, part of their estate, and theirs to draw when and how they choose. The contribution is a gift from whoever funds it.
Is it better than an ISA?
Different. The pension gets relief on the way in and 25% out tax free, and it eventually gives the lower earner income against their own personal allowance. An ISA gives access. For money that might be needed before 57, the ISA is the right home.
