On a part Age Pension they keep about £1,254.76 of it, paid back in 5.3 years; below the income-test free area they keep all £2,509.52, paid back in 2.6 years.** The reason is the Age Pension income test, which counts a UK pension as income. The UK pension is also frozen in Australia. ## Three Australian cases, worked out | Household | Years bought | Cost | UK pension a week | Gain a year | Kept a year | Payback | | --- | --- | --- | --- | --- | --- | --- | | 20 UK years, gaps 2020–21 to 2026–27, on a part Age Pension (above the free area) | 7 | £6,614.40 | £137.89 to £186.15 | £2,509.52 | £1,254.76 | 5.3 years | | The same record, income below the free area | 7 | £6,614.40 | £137.89 to £186.15 | £2,509.52 | £2,509.52 | 2.6 years | | 25 UK years, gaps 2024–25 to 2026–27, part Age Pension | 3 | £2,787.20 | £172.36 to £193.04 | £1,075.36 | £537.68 | 5.2 years | Worked out by the engine behind our calculator, all at Class 3. Pension = qualifying years ÷ 35 × the full new State Pension of £241.30 a week (2026–27). “Kept” is the gain after the Age Pension income test: half of it above the free area, all of it below. Years before April 2016 can change your starting amount, so check the Future Pension Centre’s forecast. **[Work out your own years with the voluntary NI from abroad calculator](https://decisionscalc.com/tools/uk-voluntary-ni-abroad-calculator/)**: choose Australia, say whether you are above the free area, and it shows the cost, the deadline for each year and what you keep. ## How the Age Pension income test treats it Australia counts a UK pension as income for the Age Pension. The free areas are $226 a fortnight for a single person and $396 a fortnight combined for a couple. Up to that point, extra income costs you nothing. Above it, the Age Pension falls by 50c for each $1 for a single person, and 25c each for a couple (50c for the two of you). - **On a part Age Pension you keep about half** of each extra pound of UK pension, because the other half comes off the Age Pension. That is why the first household’s payback rises from 2.6 to 5.3 years. - **Below the free area you keep it all**, as long as the extra UK pension does not take you over it. - **Tax is separate.** Australia taxes it, and lets you deduct 8% of a category A UK State Pension (ATO). ## What a frozen pension misses The UK State Pension is frozen in Australia: you get the rate from when you first claim, with no yearly increases. The one published rise takes the full rate from £241.30 to £250.70 a week in 2027–28, about 3.9%. If rises carried on at that pace, this is the gap after 10 years against someone drawing the same pension where it rises. | Household | Frozen in Australia | 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 | | 25 years plus 3 bought | £193.04 | £283.01 | £89.97 | £4,678.44 | This assumes rises continue at the one published rise (2026–27 to 2027–28); later rises are not yet known. ## The 5 April 2027 deadline - 2020–21 closes on 5 April 2027: after that this gap year can never be filled. - The first household would lose 2020–21 by waiting, and pay £184.60 more for the rest at the 2027–28 rates announced at Budget 2026. The 25-year household has no gap that old, but waiting still costs it £83.20. Read [the 5 April 2027 deadline](https://decisionscalc.com/articles/uk-voluntary-ni-deadline-april-2027/) for the transitional rules. ## What people get wrong - **“The Age Pension will take it all back.”** No. Above the free area the taper is 50c per $1 for a single person, so about half is kept. - **“It makes no difference to the Age Pension.”** It does once your income is above the free area. - **“The UK pension goes up every year.”** Not in Australia: it is frozen at your first rate. - **“I can choose Class 2.”** Only for years up to 2025–26, and only with UK work right before leaving plus work in Australia. Otherwise it is Class 3 at £18.40 a week. - **“I will pay when HMRC asks.”** HMRC does not ask. You must apply, and 2020–21 closes on 5 April 2027. ## How to buy the years from Australia 1. Check your UK National Insurance record and forecast on GOV.UK; our [UK State Pension age and forecast reader](https://decisionscalc.com/tools/uk-state-pension-age-and-forecast/) explains the figures. 2. Run the calculator with your gaps and your Age Pension position. 3. Apply with form CF83 online. For 2026–27 onwards you need 10 years in a row living in the UK or 10 years of UK-paid contributions, or the transitional rule. 4. Pay only after HMRC’s letter gives the amount and payment reference, oldest year first.

Australia counts a UK pension as income for the Age Pension income test. Above the free area ($226 a fortnight single, $396 combined for a couple) the Age Pension falls by 50c for each $1 of income, 25c each for a couple. Below the free area nothing is lost. **Is it still worth buying UK years if I live in Australia?** It can be. Our household on a part Age Pension pays £6,614.40 for 7 years and keeps about £1,254.76 a year of the £2,509.52 gain: paid back in 5.3 years. Below the free area it keeps all of it, paid back in 2.6 years. **Is my UK State Pension frozen in Australia?** 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 is the UK State Pension taxed in Australia?** Australia taxes it, and lets you deduct 8% of a category A UK State Pension (ATO). **How far back can I buy?** 2020–21 is the oldest year still open, and its deadline is 5 April 2027. Older gaps can no longer be filled. ## Related - [Voluntary NI from abroad calculator](https://decisionscalc.com/tools/uk-voluntary-ni-abroad-calculator/): years, class, cost, deadlines and what you keep in Australia. - [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 New Zealand](https://decisionscalc.com/articles/uk-state-pension-living-in-new-zealand/) · [in Canada](https://decisionscalc.com/articles/uk-state-pension-living-in-canada/) · [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) - [Services Australia: income test for Age Pension](https://www.servicesaustralia.gov.au/income-test-for-age-pension?context=22526) - [ATO: foreign pensions and annuities (myTax 2026)](https://www.ato.gov.au/individuals-and-families/your-tax-return/instructions-to-complete-your-tax-return/mytax-instructions/2026/income/foreign-income/foreign-pensions-and-annuities) - [GOV.UK: State Pension if you retire abroad](https://www.gov.uk/state-pension-if-you-retire-abroad/rates-of-state-pension) Read 13 November 2026.
