State Pension age in the UK is currently 66 for both men and women, with planned increases to 67 between 2026 and 2028, and 68 potentially later. But reaching State Pension age is not the same as being required to claim it. You have a choice — and deferring can significantly increase your income if you retire later or have other income to bridge the gap.
How State Pension Deferral Works
Under the new State Pension (which applies to anyone who reached State Pension age on or after 6 April 2016):
| Deferral period | Extra pension earned |
|---|---|
| Every 9 weeks deferred | +1% extra pension |
| 6 months deferred | ~+3.3% |
| 1 year deferred | ~+5.8% |
| 2 years deferred | ~+11.6% |
| 5 years deferred | ~+29% |
The uplift is permanent — you receive the higher pension for the rest of your life.
Worked Example: The Value of One Year’s Deferral
Scenario: Full new State Pension = £230.25/week (2026/27 estimated). You defer for exactly 52 weeks.
- Extra pension earned: 52 weeks ÷ 9 × 1% = 5.78%
- Weekly uplift: £230.25 × 5.78% = £13.31/week
- New weekly pension: £243.56/week
- Additional annual income vs claiming at 66: £692/year
Break-even analysis: You gave up one year of State Pension payments = ~£11,973. You now receive £692/year extra. Break-even point: approximately 17 years. If you live beyond age 83 (average UK life expectancy for a 66-year-old is around 85–87), you are financially better off for having deferred.
When Deferral May NOT Make Sense
Deferral is not always the right choice:
- Poor health or shorter-than-average life expectancy: If you are unlikely to reach the break-even point, taking the pension immediately gives you more overall
- Currently in a means-tested benefit: Receiving State Pension can actually help if you are eligible for Pension Credit — check before deferring if benefits are relevant to you
- No other income in the short term: If you need the money now, deferring is not a realistic option without savings or other income to cover living costs
How to Defer Your State Pension
You do not need to do anything active to defer — the State Pension does not start automatically. You only begin receiving it when you claim it.
When you reach State Pension age, DWP will write to you (approximately 2 months before your birthday) with a claim form. If you do not return it, you are effectively deferring.
To claim when you are ready:

- By phone: The Pension Service 0800 731 7898
- By post: The claim pack DWP sends you
Deferring and Taxes
State Pension income is taxable. Deferring can be tax-efficient if you are a higher-rate taxpayer in early retirement and expect to be a basic-rate taxpayer later, as a higher State Pension taken at a lower marginal rate may be more tax-efficient overall. Discuss with a financial adviser if your tax situation is complex.
Old State Pension Deferral Rules (Pre-April 2016)
If you reached State Pension age before 6 April 2016, the old rules applied:
- Uplift of 1% for every 5 weeks deferred (approximately 10.4% per year — significantly more generous)
- Option to take a taxable lump sum instead of ongoing uplift (lump sum earned interest at 2% above Bank of England base rate)
- These higher rates and lump sum options are no longer available to new claimants
