Frequently asked questions
What is the full new State Pension in 2024/25?
The full new State Pension in 2024/25 is £221.20 per week, equivalent to £11,502.40 per year. This is the amount you receive if you have 35 or more qualifying National Insurance years. The State Pension increased by 8.5% in April 2024 under the Triple Lock guarantee, which increases the State Pension each year by the highest of average earnings growth, CPI inflation, or 2.5%. The State Pension age is currently 66 for both men and women, rising to 67 between 2026 and 2028 for those born between 6 April 1960 and 5 April 1977. Future increases to age 68 are under review.
How do I get qualifying NI years for the State Pension?
You earn a qualifying National Insurance year in any tax year where you either pay sufficient NI contributions or receive NI credits. You pay NI automatically if you are employed and earn above the lower earnings limit (£6,396/year in 2024/25), or if you are self-employed and pay Class 2/4 NI. NI credits are awarded automatically in certain circumstances: if you claim Child Benefit for a child under 12, claim certain sickness or disability benefits, are a registered carer, or are on jury service. If you are not working and not receiving credits, you can make voluntary Class 3 contributions (£17.45/week in 2024/25) to fill gaps. Each qualifying year of Class 3 costs about £907 and is worth approximately £6.35 per week of additional State Pension for life.
Can I defer my State Pension to get a higher amount?
Yes. If you delay claiming the State Pension after you reach State Pension age, your pension increases for every week you defer. Under the new State Pension, deferring adds 1% for every 9 weeks deferred — equivalent to approximately 5.8% per year. There is no maximum deferral period, and you can take the deferred pension as either higher weekly payments or (if deferred for at least 12 consecutive months) an untaxed lump sum. Deferring is most beneficial for those in good health who expect to live well into their eighties, as it takes several years to recoup the pension income foregone during deferral. There is no benefit to deferring if you are still working, as the State Pension is taxable and will be taxed on top of your employment income regardless.
Does the State Pension count towards my income tax?
Yes. The State Pension counts as taxable income, but it is paid gross without any tax deducted at source. In 2024/25, the full new State Pension (£11,502/year) is well below the personal allowance of £12,570, so most people with only the State Pension pay no income tax. However, if you have other pension income, part-time work, or savings interest, the combined income may exceed the personal allowance, making your State Pension effectively partially taxable. HMRC usually collects tax on the State Pension by adjusting the tax code applied to other sources of income such as a private pension or employment income, rather than asking for direct payment.

The new State Pension: what you need to know
The new State Pension applies to those reaching State Pension age on or after 6 April 2016. It replaces the old two-tier system of basic State Pension and State Second Pension (S2P). Under the new system, your entitlement is based solely on your National Insurance record — specifically the number of qualifying years you have built up. You need a minimum of 10 qualifying years to receive any State Pension at all, and 35 qualifying years for the full amount, which is £221.20 per week (£11,502/year) in 2024/25. There is no benefit to having more than 35 qualifying years. Some people who were contracted out of the old S2P through a workplace pension may find their starting amount is lower than 35/35 of the full rate — they were allowed to build up a higher private pension in return for lower State Pension accrual. The State Pension is uprated annually under the Triple Lock: it rises by the highest of earnings growth, CPI inflation, or 2.5%.
Plugging gaps: voluntary NI contributions and NI credits
If you have gaps in your National Insurance record — perhaps from years spent studying, travelling abroad, caring for family, or earning below the NI threshold — you may be able to fill them. Voluntary Class 3 NI contributions in 2024/25 cost £17.45 per week, or £907.40 for a full year. Each additional qualifying year adds roughly £6.35 per week (£330/year) to your State Pension for life. The payback period is typically under 3 years, making it one of the highest-return "investments" available to UK residents. The government has periodically extended deadlines for filling historic gaps going back to 2006, so it is always worth checking your NI record on the government's personal tax account. NI credits are free and awarded automatically in many circumstances — including Child Benefit claims, Jobseeker's Allowance, Employment and Support Allowance, Carer's Credit, and Specified Adult Childcare Credits for grandparents who care for grandchildren under 12.
