The short answer
Canada and Australia are close cousins: both tax residents on worldwide income (no citizenship-based taxation), both use a dividend-imputation system to avoid double-taxing corporate profits, both effectively tax only half of a capital gain (Canada via a 50% inclusion rate, Australia via a 50% discount on assets held over 12 months), and both run a broad GST. The main differences: Australia's financial year runs July 1 to June 30 (Canada uses the calendar year), Australia mandates 12% superannuation contributions (Canada's RRSP is voluntary), and Australia's GST is 10% nationally vs Canada's 5% federal GST plus provincial sales tax.
Canada vs Australia at a glance
| Dimension | Canada | Australia |
|---|---|---|
| Tax authority | Canada Revenue Agency (CRA); Revenu Quebec in Quebec | Australian Taxation Office (ATO) |
| Basis of taxation | Residence -- worldwide income while resident; departure tax on emigration | Residence -- worldwide income while resident; CGT on departure for some assets |
| Tax year | Calendar year (Jan 1 - Dec 31) | Financial year July 1 - June 30 |
| Top marginal rate | 33% federal; combined with provincial tax exceeds 50% in several provinces | 45% top marginal rate + 2% Medicare levy (tax-free threshold AUD 18,200) |
| Capital gains | 50% of the gain included in ordinary income | 50% CGT discount on assets held more than 12 months (so half the gain is taxed) -- similar net effect |
| Dividends | Gross-up-and-credit (dividend tax credit) -- a form of imputation | Dividend imputation with franking credits -- the same idea, more fully built out |
| Retirement | RRSP (voluntary, pre-tax) + TFSA (tax-free) | Superannuation -- compulsory employer contributions at 12% of ordinary earnings |
| Consumption tax | 5% federal GST + provincial sales tax / HST | GST at a flat 10% nationally |
| Social / payroll | CPP 5.95% + CPP2 4%; EI | No separate social-security contribution; funded via the Medicare levy and general tax |
Two systems that rhyme
Canada and Australia arrive at similar places by similar routes. Neither taxes on citizenship, so a Canadian who becomes an Australian resident generally leaves the Canadian net (after the departure tax). Both avoid double-taxing corporate profits by giving shareholders credit for tax the company already paid -- Canada through the dividend gross-up and dividend tax credit, Australia through franking credits. And both effectively tax only half of a long-term capital gain: Canada includes 50% of the gain in income, while Australia gives a 50% discount on assets held more than 12 months. Different mechanics, very similar outcome.
The financial-year mismatch
Canada files on the calendar year. Australia's financial year runs July 1 to June 30. For a Canadian moving to Australia, income around the move has to be apportioned across two different year-ends, and foreign-tax-credit claims in either direction need careful timing -- the same issue Canadians face with the UK, just with a different cut-off.
Superannuation vs the RRSP
The biggest structural difference is retirement saving. Australia mandates superannuation: employers must contribute 12% of ordinary earnings (2025/26) into a super fund, on top of salary. Canada's RRSP is voluntary -- you choose how much to contribute, up to your limit, and deduct it. Australia's compulsory system produces large preserved balances; Canada's relies on individual discipline plus the CPP. For a Canadian relocating, super contributions are not optional and are taxed under their own concessional regime.
Consumption tax and rates
Australia's GST is a flat 10% nationally, with no separate provincial layer. Canada's is 5% federal plus a provincial sales tax (harmonised into 13-15% HST in many provinces), so the combined Canadian rate can approach Australia's or exceed it depending on the province. Australia's top marginal rate is 45% plus a 2% Medicare levy; Canada's top is 33% federal but combined with provincial tax exceeds 50% in several provinces -- so top-end Canadians and Australians face broadly comparable peak rates.
Key facts
Frequently asked questions
Are Canada and Australia really that similar on tax?
Structurally, yes -- more than almost any other pair. Both tax residents on worldwide income with no citizenship-based taxation, both use dividend imputation to avoid double-taxing corporate profits, both effectively tax half of a long-term capital gain, and both run a broad GST. The headline differences are the July-to-June financial year, compulsory 12% superannuation, and a flat 10% GST -- not the fundamentals.
If I move from Canada to Australia, do I keep paying Canadian tax?
Generally no, once you become a non-resident of Canada -- but you pay Canada's departure tax (a deemed disposition of most property at fair market value) on the way out, then you are taxed by the ATO on the residence basis. Neither country taxes on citizenship, so there is no permanent dual-filing trap. Watch the financial-year mismatch in your year of arrival.
How does Australia's 50% CGT discount compare to Canada's 50% inclusion?
They reach almost the same place. Canada includes 50% of a capital gain in your ordinary income and taxes that at your marginal rate. Australia taxes the full gain at marginal rates but first discounts it by 50% if you held the asset more than 12 months. Either way, roughly half the gain is taxed at ordinary rates -- the difference is mostly in the holding-period condition Australia attaches to its discount.
