How much extra do I get if I defer my State Pension?

For every 9 weeks you defer, your State Pension increases by 1%. That works out to approximately 5.8% extra per year. On the full new State Pension of £230.25 per week, deferring for one year adds approximately £13.36 per week (£694 per year) for life. This increase is also protected by the triple lock, so it rises each year.

Is it worth deferring the State Pension?

It depends on your health, other income, and tax situation. The break-even point is approximately 17 years. If you defer for 1 year, you forgo £11,973 in pension payments but gain £694 per year permanently. You need to live approximately 17 years past the point you start claiming to come out ahead. If you're in good health and have other income, it can be worthwhile. If you need the money, claim it.

Can I defer my State Pension and claim it as a lump sum?

Under the new State Pension (from 6 April 2016), you can no longer take a lump sum. You can only get a higher weekly pension. Under the old State Pension (pre-2016), there was an option for a lump sum with interest, but this only applies to people who reached State Pension age before 6 April 2016.

How do I defer my State Pension?

You do not need to do anything — if you don't claim your State Pension when you reach State Pension age, it is automatically deferred. To start claiming later, contact the Pension Service on 0800 731 7898 or claim online at gov.uk/get-state-pension. You can claim backdated payments for up to 12 months.

State Pension Deferral UK — Is It Worth Delaying Your State Pension? | PocketWise

You do not have to claim your State Pension as soon as you reach State Pension age. Deferring it means you give up payments now in exchange for a higher amount later. Here is whether the trade-off works in your favour.

How Deferral Works

Detail	New State Pension (from 6 April 2016)
Increase per 9 weeks deferred	1%
Annual increase	~5.8%
Lump sum option?	No — higher weekly pension only
Minimum deferral period	9 weeks (to gain any increase)
Maximum deferral period	No maximum — you can defer as long as you want
Is the increase guaranteed?	Yes — it becomes part of your pension for life
Does the increase rise with inflation?	Yes — protected by the triple lock

The Numbers — Full New State Pension 2026/27

Scenario	Weekly amount	Annual amount
Claiming at State Pension age (no deferral)	£230.25	£11,973
Deferred 1 year	£243.61	£12,668
Deferred 2 years	£257.00	£13,364
Deferred 3 years	£270.36	£14,059
Deferred 5 years	£297.11	£15,450

What You Give Up vs What You Gain

Deferral period	Pension foregone	Extra per year (for life)	Break-even point
1 year	£11,973	£694	~17 years
2 years	£23,946 + Year 1 increase	£1,390	~17 years
3 years	~£37,310	£2,086	~17 years
5 years	~£65,337	£3,476	~17-18 years

The break-even point is consistently around 17 years regardless of how long you defer. If you defer for 1 year from age 67, you need to live to approximately 84 to come out ahead.

Should You Defer? — Decision Guide

Your situation	Defer?	Reasoning
Good health, family history of longevity	Consider it	More likely to live past break-even
Still working and don’t need the income	Good candidate	Avoid adding State Pension to employment income (higher tax)
Other pension/investment income covering expenses	Worth considering	The extra income later could be valuable
No other income — need the pension to live on	No — claim it	You need the money now
Poor health or reduced life expectancy	Probably not	Less likely to reach the break-even point
You’d invest the pension if you received it	Compare returns	5.8% guaranteed return is hard to beat tax-free, but consider your tax position

Tax Implications

While Deferring

Situation	Tax position
Working and deferring	You avoid adding State Pension to your employment income — could keep you in a lower tax band
Self-employed and deferring	Same — may reduce your overall tax bill during working years
Not working and deferring	Less beneficial — you’re giving up tax-free or basic-rate income

When You Start Claiming

Situation	Tax position
State Pension only income (below Personal Allowance)	No tax — but the higher deferred pension may push you above £12,570
State Pension + other income	The higher pension adds to your taxable income
Higher rate taxpayer in retirement	The extra pension is taxed at 40%+ — less beneficial

Worked Example — Tax Impact

Detail	Claim at 67	Defer 1 year
State Pension	£11,973/year	£12,668/year
Private pension income	£8,000/year	£8,000/year
Total income	£19,973	£20,668
Personal Allowance	£12,570	£12,570
Taxable income	£7,403	£8,098
Tax at 20%	£1,481	£1,620
Net income after tax	£18,492	£19,048

In this example, deferring adds £556 per year after tax. The break-even point shifts to approximately 21 years when tax is included (because you’re also paying tax on the extra pension).

Deferral vs Investing

What if you claimed the pension and invested it instead?

Scenario	Detail
Claim at 67 and invest £11,973/year for 1 year	You have £11,973 plus any growth
Defer for 1 year — extra £694/year for life	Guaranteed, inflation-linked
Investment would need to return	~5.8% net per year just to match deferral
Key advantage of deferral	Guaranteed, inflation-linked, no investment risk
Key advantage of investing	You have a capital sum, flexibility, can be inherited

For risk-averse people, the guaranteed 5.8% return from deferral is very attractive. For those comfortable with investment risk, investing the pension may provide more flexibility.

How to Defer

Action	Detail
To defer	Simply do not claim when you reach State Pension age — it defers automatically
HMRC letter	You’ll receive a letter about 2 months before your State Pension age — you can ignore it if you want to defer
To start claiming later	Contact the Pension Service on 0800 731 7898 or claim online at gov.uk/get-state-pension
Backdating	You can claim up to 12 months of backdated payments (at the un-deferred rate)

Backdating

Option	Detail
Claim with no backdating	Your enhanced pension starts from when you claim
Claim with up to 12 months backdating	You receive the arrears at the original (lower) rate, and your ongoing pension is recalculated based on actual deferral period minus the backdated months

Example: If you deferred for 2 years then decide to claim with 12 months backdating, you receive one year’s arrears at the original rate plus an ongoing pension enhanced for 1 year of deferral (not 2).

Old State Pension Rules (Pre-6 April 2016)

If you reached State Pension age before 6 April 2016, different (more generous) rules apply:

Feature	Old rules
Increase per year deferred	~10.4% (1% per 5 weeks)
Lump sum option?	Yes — you could take a lump sum with interest
Lump sum interest rate	Base rate + 2%
Tax on lump sum	Taxed at your highest rate in the year you receive it

The old rules were more generous. If you are still deferring under the old rules, take advice before claiming — the lump sum option may or may not be better than the weekly increase depending on your circumstances.

Special Situations

Already Deferring and Changed Your Mind

Situation	What to do
Want to stop deferring and start claiming	Contact the Pension Service — you can claim at any time
Want backdated payments	Request up to 12 months backdating when you claim
Partner has died while you were deferring	Your deferred State Pension is yours — it doesn’t transfer. But check inherited State Pension eligibility separately

Deferring and Care Home Fees

Point	Detail
If you need care and are self-funding	A higher pension is still preferable — more income to cover costs
Local authority financial assessment	Your State Pension counts as income whether you claim it or not — deferring does not hide income from means-testing

Important: Local authorities assess your entitlement to State Pension, not just what you receive. Deferring does not reduce your assessed income for care home fees.
