Deferring State Pension 2026/27: 5.8% Extra & Break-Even

Deferring your State Pension: what you get and how long it takes to pay back

You do not have to claim your State Pension at State Pension age. If you wait, you can get a one-off payment for up to 52 weeks or a permanently higher weekly pension.

Short answer

If you reached State Pension age on or after 6 April 2016, your State Pension increases by 1% for every 9 weeks you defer, just under 5.8% a year. Deferring a full new State Pension (£241.30 a week in 2026/27) for 52 weeks adds about £13.99 a week for life. Alternatively you can take up to 52 weeks of arrears as a one-off payment (£12,547.60 for a full year), with no interest. GOV.UK says it takes over 15 years to get back 52 weeks of deferred full new State Pension.

Your options

Extra State Pension: you must defer for at least 9 weeks. Each 9 weeks adds 1% to the weekly amount for life.
One-off arrears payment: up to 52 weeks of the pension you deferred, paid without interest.
Both: for example, defer 78 weeks, take 52 weeks as arrears and receive extra pension for the other 26 weeks (£6.97 a week on the full rate, according to GOV.UK).

Worked example: is a year of deferral worth it?

	Amount
Pension given up by deferring 52 weeks	£12,547.60
Extra pension	£13.99 a week = £727.48 a year
Simple payback before tax and uprating	about 17.2 years
With a 20% tax rate on the extra pension	about 21.6 years

The extra amount is usually uprated by CPI each year, which shortens the period somewhat; GOV.UK summarises it as over 15 years. Compare that with life expectancy, health, other income and your tax position. By contrast a confirmed voluntary NI year that adds £358.50 a year for £956.80 pays back in about 2.7 years.

When deferral does not build up

You cannot build up deferred State Pension while you or your partner are getting certain benefits, or for time spent in prison. Extra payments from deferral can be taxed. For people living abroad the extra amount may not be uprated each year.

Common mistakes

Assuming the arrears lump sum earns interest. It does not.
Deferring while a partner gets a benefit that stops the increase.
Forgetting that deferral increases your taxable income later, possibly at a higher rate.

Frequently asked questions

How much does deferring the State Pension add?

HMRC: ask which contributions you may pay, the exact price, application or transitional conditions, payment reference and allocation. Check overseas eligibility and application guidance.

Below State Pension age: use the Future Pension Centre to check whether a particular payment increases your pension, subject to its service scope.
