Canada vs UK Tax — Side-by-Side Comparison for 2025 / 2026-27
Canada and the UK both run progressive PAYE-style income tax with mandatory pension contributions and universal healthcare — but the structural details (provincial vs national, CPP vs NI, RRSP vs pension, TFSA vs ISA) differ enough to materially change your take-home if you cross the Atlantic. This page compares federal + provincial / national income tax, payroll levies, and retirement schemes using CRA 2025 federal + Ontario figures and HMRC 2026-27 figures (rest of UK).
Take-home pay on the same nominal salary
Same numeric amount taxed as both a CAD salary (CRA federal + Ontario + CPP/EI) and a GBP salary (HMRC + Class 1 NI). Currencies aren't directly comparable — this is a structural tax comparison, not a cost-of-living comparison.
| Gross salary | CA fed + ON | CPP + EI | CA take-home | UK income tax | UK NI | UK take-home | Gap |
|---|---|---|---|---|---|---|---|
| $50,000 | $6,793 | $3,587 | $39,621 | $7,486 | $2,994 | $39,520 | +$101 |
| $100,000 | $21,057 | $5,508 | $73,436 | $27,432 | $4,011 | $68,557 | +$4,878 |
| $150,000 | $38,709 | $5,508 | $105,783 | $54,332 | $5,011 | $90,658 | +$15,125 |
| $250,000 | $79,333 | $5,508 | $165,159 | $99,332 | $7,011 | $143,658 | +$21,502 |
Gap shows Canada take-home minus UK take-home. Canada uses Ontario as a representative middle-tax province; Atlantic provinces tax more, Alberta/Yukon less. UK figures use rest-of-UK 2026-27 (Scotland uses different rates).

Retirement: RRSP / TFSA vs UK pension / ISA
Both countries pair tax-deferred and tax-free wrappers. Canada: RRSP (18% earned income, $32,490 cap; tax-deferred) + TFSA ($7,000/yr; tax-free). UK: workplace pension / SIPP (£60k Annual Allowance; tax-deferred) + ISA (£20,000/yr; tax-free) + Lifetime ISA (£4k/yr with 25% government top-up until 50). The UK pairing is more generous on tax-free room (ISA cap is ~3× TFSA).
Mandatory floor differs. Canada has no mandatory employer retirement contribution beyond CPP — RRSP is fully voluntary. The UK's 8% auto-enrolment minimum (3% employer + 5% employee) sets a floor that protects employees who don't actively elect. CPP is comparable to UK State Pension via NI: both fund a defined-benefit basic pension on top of personal savings.
Cross-border cautions. The Canada-UK treaty recognises RRSPs and UK pensions as 'pensions' for treaty purposes (deferred until withdrawal). Direct transfers between RRSP and UK QROPS schemes are not generally permitted; both stay in their home country with withdrawals taxed in the country of residence (with foreign tax credit). TFSA loses tax efficiency on UK residency (treated as taxable account). ISA loses tax efficiency on Canadian residency.
If you're moving Canada → UK
- Tax residency: Canadian residency ends when you sever 'significant residential ties' (home sold, spouse joins, dependants relocate). UK residency triggers under the SRT — 183+ days, or 91+ days with UK ties.
- RRSP: Stays in Canada; treaty-recognized as UK pension (no annual UK taxation on growth). Withdrawals taxed in both — Canada applies 25% withholding (NR4); UK taxes at marginal with foreign tax credit. Plan timing of any withdrawal carefully.
- TFSA caution: UK does not recognize TFSA as tax-free — growth and withdrawals are UK-taxable. Consider closing TFSA and moving to ISA after UK residency starts. Capital losses on closure may offset other gains in the year of departure.
- Capital gains: Canada deems disposition at departure on world property (the 'departure tax') — calculate the unrealized gain that crystallizes. Election to defer is possible by posting security with CRA; UK then steps up basis on entry.
- Property: SDLT (or LBTT/LTT) replaces provincial Land Transfer Tax. UK FHB relief up to £425k purchase, partial up to £625k.
- NHS access: Available immediately to UK residents — no provincial healthcare premium equivalent.
If you're moving UK → Canada
- Tax residency: Canadian residency triggers via 'significant residential ties' (home, spouse, dependants in Canada) or 183+ days. UK residency ends per the SRT — typically when you leave for full-time work overseas.
- UK pension: Stays in UK; treaty-recognized as Canadian pension (no annual Canadian taxation on growth). Withdrawals taxed at marginal Canadian rate; UK 25% lump-sum is NOT tax-free under Canadian rules — taxed as ordinary income.
- ISA caution: Lose tax efficiency on Canadian residency — CRA taxes growth and dividends as a regular taxable account. Consider closing or moving to cash before Canadian move.
- Higher take-home in Alberta: AB flat 10% provincial tax beats most UK higher-band scenarios. ON middle-tax; QC highest.
- Property: Provincial Land Transfer Tax (e.g. ON ~$8k on $500k home; Toronto MLTT doubles within city). Foreign Buyer Tax 25% in BC and ON for non-residents (PR/citizens exempt).
- RRSP / TFSA opening: Once tax-resident in Canada, contribution room starts accruing. RRSP requires earned income; TFSA from age 18.
