Figures name their source and the date they were read. --- UK State Pension · Canada # Living in Canada with UK National Insurance gaps: what buying the missing years is worth **Someone in Canada with 20 UK qualifying years and gaps from 2020–21 to 2026–27 can buy 7 years for £6,614.40, lifting their UK State Pension from £137.89 to £186.15 a week: £2,509.52 a year more, paid back in 2.6 years.** OAS and CPP are not cut for it, though the GIS and the Allowance can be. The catch is that the pension is frozen in Canada: after 10 years at the one published rise, £186.15 a week would be £86.76 a week behind the UK rate. ## Two Canadian households, worked out | Household | Years bought | Cost | UK pension a week | Kept a year | Payback | | --- | --- | --- | --- | --- | --- | | 20 UK years, moved to Canada, gaps 2020–21 to 2026–27 | 7 | £6,614.40 | £137.89 to £186.15 | £2,509.52 | 2.6 years | | 15 UK years, one gap left to fill: 2020–21 | 1 | £956.80 | £103.41 to £110.31 | £358.80 | 2.7 years | Worked out by the engine behind our calculator, at Class 3. Pension = qualifying years ÷ 35 × the full new State Pension of £241.30 a week (2026–27). “Kept” assumes you get neither the GIS nor the Allowance. People with years before April 2016 may have a different starting amount; the Future Pension Centre’s forecast is the one to trust. **[See your own figures in the voluntary NI from abroad calculator](https://decisionscalc.com/tools/uk-voluntary-ni-abroad-calculator/)**: choose Canada and it lists the years you can buy, the cost and deadline of each, and what the extra pension is worth. ## What living in Canada changes - **OAS and CPP stay whole.** Neither is reduced because you have a UK State Pension. - **The GIS and the Allowance can fall.** Both are based on your previous year’s income, and the Allowance asks for foreign pension income. If you expect either, the real gain from buying years is lower than our kept figure. - **It is taxed in Canada.** Canada taxes it: report the gross foreign pension in Canadian dollars (CRA line 11500). - **It is frozen.** You get the rate from when you first claim, with no yearly increases while you live in Canada. ## What a frozen pension misses The only published rise so far takes the full rate from £241.30 to £250.70 a week in 2027–28, about 3.9%. Someone living in the UK gets rises like that each April. In Canada you do not. If the rises carried on at that pace, here is the gap after 10 years. | Household | Frozen in Canada | If it rose, after 10 years | Behind a week | Behind a year | | --- | --- | --- | --- | --- | | 20 years plus 7 bought | £186.15 | £272.91 | £86.76 | £4,511.52 | | 15 years plus 1 bought | £110.31 | £161.72 | £51.41 | £2,673.32 | This assumes rises continue at the one published rise (2026–27 to 2027–28); nobody knows the later ones yet. A frozen pension still pays the same pounds for life, so the payback above does not change. ## The 5 April 2027 deadline - 2020–21 closes on 5 April 2027: after that this gap year can never be filled. - For the first household, waiting loses 2020–21 and adds £184.60 to the cost of the rest, at the 2027–28 rates announced at Budget 2026. - For the second household it is all or nothing: its only gap is 2020–21, so after 5 April 2027 there is nothing left to buy. The detail is in [the 5 April 2027 deadline](https://decisionscalc.com/articles/uk-voluntary-ni-deadline-april-2027/). ## What people get wrong - **“The UK pension will be taken off my OAS or CPP.”** Neither is reduced for it. - **“Low income means it does not matter.”** On the GIS or the Allowance it can matter, because they look at last year’s income. - **“I can buy older years later.”** You can only pay for the past six years. 2020–21 is the oldest still open, until 5 April 2027. - **“Class 2 works for me.”** Only for years up to 2025–26, and only if you worked in the UK immediately before leaving and work in Canada. Otherwise it is Class 3 at £18.40 a week. - **“I report the net amount.”** The CRA asks for the gross foreign pension, in Canadian dollars. ## How to buy the years from Canada 1. Look up your UK National Insurance record and forecast on GOV.UK. The [UK State Pension age and forecast reader](https://decisionscalc.com/tools/uk-state-pension-age-and-forecast/) explains your date and amount. 2. Use the calculator to see which gaps are worth filling. 3. Apply with form CF83 online. From 2026–27 you need 10 years in a row living in the UK or 10 years of UK-paid contributions, unless the transitional rule covers you. 4. Do not pay until HMRC writes with the amount and payment reference. Then pay 2020–21 first.

The Guaranteed Income Supplement and the Allowance are based on your previous year’s income, and the Allowance asks for foreign pension income. So if you get either, a bigger UK pension can mean a smaller payment. **Is the UK State Pension frozen in Canada?** Yes. You get the rate from when you first claim, with no yearly increases. If UK rises carried on at 3.9% a year, £186.15 a week would be £86.76 a week behind after 10 years. **How do I report it on my Canadian tax return?** Canada taxes it: report the gross foreign pension in Canadian dollars (CRA line 11500). **I only have one gap year left to buy. Is it worth it?** For our 15-year example, 2020–21 costs £956.80 and adds £358.80 a year, paid back in 2.7 years. It must be paid by 5 April 2027, or it is gone for good. ## Related - [Voluntary NI from abroad calculator](https://decisionscalc.com/tools/uk-voluntary-ni-abroad-calculator/): years, class, cost, deadlines and what you keep in Canada. - [UK State Pension from Ireland and abroad](https://decisionscalc.com/articles/uk-state-pension-from-abroad/) · [the 5 April 2027 deadline](https://decisionscalc.com/articles/uk-voluntary-ni-deadline-april-2027/) · [State Pension age and forecast reader](https://decisionscalc.com/tools/uk-state-pension-age-and-forecast/) - [The 10-year test](https://decisionscalc.com/articles/uk-voluntary-ni-10-year-test/): who can still buy Class 3 from abroad from 2026 to 2027, and the old 3-year rule. - Other countries: [UK State Pension in Australia](https://decisionscalc.com/articles/uk-state-pension-living-in-australia/) · [in New Zealand](https://decisionscalc.com/articles/uk-state-pension-living-in-new-zealand/) · [in Ireland](https://decisionscalc.com/articles/uk-state-pension-living-in-ireland/) · [in the US](https://decisionscalc.com/articles/uk-state-pension-living-in-the-us/) ## Sources - [GOV.UK: Voluntary National Insurance](https://www.gov.uk/voluntary-national-insurance-contributions) (rates, the six-year limit, deadlines) and [if you live or work abroad](https://www.gov.uk/voluntary-national-insurance-contributions/if-you-live-or-work-abroad) (Class 2 ended, the 10-year test) - [GOV.UK: State Pension if you retire abroad](https://www.gov.uk/state-pension-if-you-retire-abroad/rates-of-state-pension) - [Canada.ca: the Allowance, income to report](https://www.canada.ca/en/services/benefits/publicpensions/old-age-security/guaranteed-income-supplement/allowance/apply.html) - [CRA: line 11500, foreign pension income](https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/tax-return/completing-a-tax-return/personal-income/line-11500-other-pensions-superannuation.html) Read 13 November 2026.
