Should both partners defer their State Pension, or just one?
State Pension deferral pays about 5.8% more per year deferred, recovered only by living long enough. For a couple the useful insight is that the two decisions are separate and should not match: the partner with the better longevity prospects and the less pressing income need is the one for whom deferral works.
- Two decisions: each partner's State Pension is their own and is deferred independently.
- The bet: about 5.8% a year more, recovered after roughly seventeen years of receipt.
- The survivor: very little of a deferred State Pension passes on, so deferral does not protect a spouse.
- The income: one partner deferring is affordable in a way that both deferring often is not.
01 The decisions are independent
Each partner has their own State Pension based on their own National Insurance record, and each can defer independently. There is no household election and no interaction between the two decisions in the rules.
That means the right answer can be different for each of them, and frequently is. Reaching State Pension age at different dates, with different records, different health and different other income, produces different arithmetic.
Households nevertheless tend to do the same thing for both, because the decision is made once and applied. The deferral arithmetic deserves running twice.

02 Who should defer
Deferral is recovered by living long enough, so the partner with the better longevity prospects has the stronger case — and for most couples that is a real difference rather than a theoretical one.
It also depends on the income need. Deferring means going without that income for the period, so the partner whose income the household can most easily do without is the one for whom deferral is affordable. Deferring both at once usually is not.
And the tax position matters. A partner still working past State Pension age can defer and claim once their earnings stop, moving the whole pension from a higher band to a lower one — an effect separate from and often larger than the 5.8%.
Shows: the income forgone by deferring one State Pension against deferring both, and what each buys. Ignores: tax, means-tested benefits, and each partner's actual longevity.
On the defaults above, the worked example shows £12,548. One partner deferring gives up £12,548 and gains £627 a year; both deferring doubles each figure and doubles the income the household has to do without.

03 What deferral does not do
It does not protect the survivor. Under the new State Pension very little passes to a spouse, so a deferred pension enhanced by years of waiting largely dies with the person who deferred it. Deferral is a bet on your own life rather than provision for a partner.
It also interacts badly with means-tested benefits: a deferred State Pension is treated as if it were being received for Pension Credit purposes, so the household loses the income and gains nothing in the calculation.
For a couple wanting to raise the survivor's income, the effective routes are different — a joint-life annuity, a survivor's pension in a scheme, or building the lower earner's own National Insurance record.

Households make this decision once and apply it to both people, and it is two decisions. Deferral is a bet on living long enough to collect, so the partner with the better health and family history has the stronger case — and the partner still working has a separate and often larger tax argument for waiting until their earnings stop. What deferral does not do is help the survivor, because almost none of the new State Pension passes on. If protecting a spouse is the objective, this is the wrong instrument entirely.
FAQ
Do we have to make the same decision?
No. Each partner's State Pension is their own and is deferred independently, and the right answer is frequently different for each — different records, different health, different other income and different State Pension ages.
Does deferral help my spouse after I die?
Very little. Under the new State Pension only a protected payment and, in some cases, part of an additional State Pension can pass on. A deferred pension enhanced by years of waiting largely dies with the person who deferred it.
Can we defer while claiming Pension Credit?
You can, and it makes the household worse off. A deferred State Pension is treated as if it were in payment for Pension Credit purposes, so you lose the income and gain nothing in the calculation.
