Updated Checked by the Tax-Services.ca editorial team How we check
The highest taxes in the world depend on what you measure, and we couldn’t confirm a single world ranking on an official page. What we could confirm is the OECD’s 2025 figure for the tax wedge on a single worker at the average wage: it averaged 35.1% across member countries, from about 52.5% in Belgium and 49.3% in Germany down to zero in Colombia.
What does highest taxes actually mean?
People use the phrase for at least three different things. One is the top income tax rate. Another is total tax as a share of the whole economy. The third is how much of a typical paycheque goes to tax, and that’s the one the OECD reports each year in its Taxing Wages series.
The tax wedge counts income tax and social security paid by the worker and the employer, then compares it with the full cost of employing that person. So a country with a modest top rate can still show a heavy wedge if payroll charges are large.
We didn’t find a reliable source that ranks every country by top rate or by total tax take, and the lists that circulate online rarely say the year or the definition. Treat any of them with suspicion, including ones that name a country and a single percentage.
Where does Canada sit?
Canada isn’t in the OECD summary lines we could read, so we won’t put a rank or a percentage on it. That’s a gap, and we’d rather show it than guess. The number you can do something about is your own, and we can calculate it for Canada.
Take a $300,000 salary. In Ontario the income tax calculator shows $114,093.67 of federal and Ontario tax, an average of 38.0%, plus $5,769.52 for CPP and EI. In Alberta the same pay gives $100,688.87, or 33.6%. Same country, a gap of $13,404.80 a year, or about $1,117 a month. Picture two colleagues on identical pay, one in Calgary and one in Mississauga. Over a year, the Calgary one keeps the price of a decent used car more than the other, and nobody in either city did anything clever.
Which province takes the most from a high earner?
Here’s the tax on the next dollar for someone with $400,000 of taxable income, federal and provincial together, from the engine behind our marginal tax rate calculator.
| Province | Combined top rate |
|---|---|
| Nova Scotia | 54.00% |
| Newfoundland and Labrador | 53.80% |
| Ontario | 53.53% |
| Quebec | 53.31% |
| Prince Edward Island | 53.00% |
| New Brunswick | 52.50% |
| Manitoba | 50.40% |
| Alberta | 48.00% |
| Saskatchewan | 47.50% |
Outside Quebec the federal share is 33% and the rest is the province. Quebec residents get a federal abatement, so their federal share is lower. In Newfoundland and Labrador the top rate goes to 54.8% above $1,141,275. We left out British Columbia and the territories, since we haven’t fully confirmed every 2026 figure there.
Why the top rate overstates what you pay
A top rate applies only to income above the top step. On $300,000 in Ontario, the average is 38.0% while the next dollar costs more than 50%. Almost nobody pays the headline rate on all their income.
Capital gains work differently again. Only part of a gain is taxable, and the calculator uses a 50% inclusion rate for 2026. That rate isn’t stated on a CRA page we could read, so we treat it as our working figure. The proposed rise to two-thirds was cancelled in the Prime Minister’s release of 21 March 2025. Try your own case in the capital gains tax calculator.
Which number should you use to compare countries?
It depends on the question. If you’re asking what a country takes from a middle-income worker, use the tax wedge. If you’re weighing a big raise or a promotion, use the marginal rate, because it tells you what the next dollar is worth after tax. If you’re asking how heavy the state is overall, the share of the economy is the tool, and that one includes corporate, sales and property taxes that never touch your pay slip. Mixing the three is how headlines like “world’s highest taxes” get written, and why the same country can look both heavy and light in one week of news.
A single-year ranking also moves. Social security rates, tax brackets and wages all shift, so a country can rise or fall several places without changing much at all.
Taxes are more than the rate on your pay
A country’s headline can hide the rest. Sales tax, property tax and payroll charges all take a share, and what you get back in services and benefits is the other side of the ledger. Comparing take-home pay across countries also means comparing housing, health care and child care, which no rate table captures. Paying a few bucks more in tax for care you’d otherwise buy privately isn’t the same as paying them for nothing.
For your own pay, the take-home pay calculator is the honest measure. It shows what’s left after every payroll deduction, and our guide on how to calculate how much tax you will pay walks through one case.
What this page is based on
The tax wedge figures come from the OECD’s Taxing Wages 2026 report, which covers 2025. We read them through search summaries of the report because the OECD pages blocked our tool, so check the figures on the OECD site. Canadian rates are the 2026 federal and provincial schedules from the CRA and provincial governments. This site isn’t linked to any government or to the OECD.
Frequently asked questions
Which country has the highest tax wedge?
In the OECD's Taxing Wages 2026 report, Belgium is highest for a single average earner in 2025 at about 52.5%, ahead of Germany at 49.3%.
What is the tax wedge?
It's income tax plus employee and employer social security, as a share of the total cost of employing someone.
Is Canada's tax the highest in the world?
We couldn't confirm a Canadian rank on an official page. Your own rate depends on income and province.
What is the highest tax rate in Canada?
For a $400,000 earner our engine shows 54.00% in Nova Scotia and 53.53% in Ontario, federal and provincial combined.
Does the top rate apply to all my income?
No. It applies only to income above the top step, so your average rate is lower.
