Check Your State Pension Forecast: A Step-by-Step Guide for 2026

The full new state pension in 2025/26 is £221.20 per week — that's £11,502 per year, or approximately £230,000 over 20 years of retirement. Yet millions of UK adults have no idea what they'll actually receive because they've never checked their forecast. According to the DWP, only 34% of working-age adults have ever viewed their state pension forecast online. The remaining 66% are guessing — and many will receive less than the full amount because of gaps in their National Insurance record they didn't know existed. Checking takes less than 10 minutes and could be worth thousands of pounds. Your forecast shows how many qualifying years of National Insurance contributions you have, how many you need for the full pension (35 years), whether you have any gaps, and what your projected weekly pension amount is based on your current record. Critically, it also highlights where you can buy missing years. The deadline to buy back NI years going as far back as 2006/07 has been extended, but it won't last indefinitely. Each missing year costs approximately £824 to buy (Class 3 voluntary contributions for 2025/26) and adds roughly £328 to your annual pension for life. That's a payback period of just 2.5 years — an extraordinary return.

Visit gov.uk/check-state-pension. You'll need a Government Gateway or GOV.UK One Login account. If you don't have one, you can create it during the process — you'll need your National Insurance number, a UK mobile phone, and a form of ID. Step one: log in and navigate to "Check your State Pension." The system will show your forecast: what you'll receive per week based on your current record, and what you'd receive if you continue contributing until state pension age. Step two: click "View your National Insurance record" (linked from the forecast page, or go directly to gov.uk/check-national-insurance-record). This shows every tax year from when you started working, marked as either "full year," "year is not full," or "no record." Step three: identify any gaps. Look for years marked as "not full" or years where you were working but no contributions appear. Common causes include: time spent abroad, self-employment with low profits (below the Class 2 NI threshold), career breaks for caring responsibilities, gaps between jobs, and administrative errors. Step four: note the earliest gap year and the cost to fill it. The further back the gap, the cheaper it may be to fill (older years' voluntary contributions were set at lower rates). However, the deadline for buying back years from 2006-2016 is time-limited.

Not every NI gap needs filling. The key calculation is whether buying the year would increase your pension. If you already have (or will have by state pension age) 35 qualifying years, additional years don't increase your pension — you're already at the maximum. If you have fewer than 35 qualifying years and won't reach 35 through future employment, buying missing years makes financial sense. The maths is compelling: buying one year of Class 3 voluntary NI contributions costs approximately £824 (2025/26 rate). This adds 1/35th of the full pension to your entitlement, which is approximately £6.29 per week or £328 per year. If you receive the state pension for the average retirement duration (approximately 20 years for men, 23 years for women based on ONS life expectancy data), that £824 investment yields £6,560-7,544 over your retirement. That's an 8-9x return with zero risk — backed by the UK government. For people with multiple gaps, the total investment can be significant (five gaps = approximately £4,120) but the lifetime return is proportionally large. Note: if you receive certain benefits (Carer's Allowance, Child Benefit for a child under 12, Universal Credit), you may get NI credits automatically. Check your record to see if credits have been applied — sometimes they're missing due to administrative issues and can be claimed retrospectively.

NI credits count as qualifying years without requiring cash contributions. Many people are entitled to credits they're not receiving. Child Benefit credits: if you're claiming Child Benefit for a child under 12, you automatically receive NI credits. But if your partner claims Child Benefit and you're the one staying home or working part-time, the credits go to them — not you. You can transfer the credits by completing form CF411A. This is one of the most common and costly oversights in the UK pension system, particularly affecting mothers who stopped working or reduced hours. Carer's credits: if you care for someone for 20+ hours per week and they receive a disability benefit, you can claim Carer's Credit (not Carer's Allowance — the credit has no income requirement). Jobseeker's Allowance and Universal Credit: periods on these benefits should generate automatic NI credits, but check your record to confirm they've been applied. Jury service: time spent on jury service earns NI credits. If your record shows a gap for a year when you served on a long jury case, contact HMRC. Armed Forces: service personnel receive credits automatically, but reservists may need to claim separately for training periods.

With the ISA deadline on April 5, 2026 also marking the end of the current tax year, there's a dual pension opportunity for forward planners. First, any voluntary NI contributions for the 2025/26 tax year must be made before the standard deadline (typically six years after the year in question, but the extended deadline for older years is a special case). Second, if you're using salary sacrifice to boost pension contributions, doing so before April 5 maximises the benefit for this tax year. For those approaching state pension age, checking your forecast now gives you time to buy any missing years before you start claiming. Once you're receiving the pension, you can still buy back years to increase it, but the administrative process is longer. The state pension is increasingly important in the context of falling private pension returns and longer life expectancies. The triple lock (pension increases by the higher of inflation, average earnings growth, or 2.5%) means the state pension maintains its purchasing power over time — unlike many private pensions. Even if you have substantial private pension savings, the state pension provides a guaranteed, inflation-protected income floor that reduces reliance on volatile investment returns. Maximising it is one of the smartest financial moves available to UK workers.

Once you know your projected state pension and have identified any gaps, create an action plan. If you have gaps that are worth buying: contact HMRC's NI helpline (0300 200 3500) to confirm the cost and process for each year. They can also confirm whether buying will actually increase your pension — essential before spending money. You can pay by bank transfer, debit card, or cheque. If you're missing credits: submit the relevant forms (CF411A for Child Benefit credit transfer, Carer's Credit application online at gov.uk). HMRC can backdate credits in many cases. If you have 35+ qualifying years: no action needed on state pension specifically, but use this as a prompt to review your total retirement provision. Does your workplace pension plus state pension provide enough income for the retirement you want? Use the PLSA's Retirement Living Standards as a benchmark: £14,400/year for minimum, £31,300/year for moderate, and £43,100/year for comfortable (single person, 2025 figures). If your combined pension provision falls short, consider increasing workplace pension contributions or opening a SIPP.
