Question 1

What is income tax in Canada?

Accepted Answer

Income tax is money the government collects from your earnings to pay for public services like healthcare, roads, and schools. Canada uses a progressive tax system, meaning the more you earn, the higher percentage you pay on the portion above each threshold. Your first dollars are taxed at the lowest rate (15% federally), and only the income above each bracket boundary is taxed at the higher rate.

Question 2

What is CPP (Canada Pension Plan)?

Accepted Answer

CPP is a mandatory retirement savings plan. Both you and your employer contribute a percentage of your pay (5.95% each in 2026). The money goes into a national fund and is paid back to you as a monthly pension when you retire (starting as early as age 60). If you work in Quebec, you contribute to QPP instead, which works similarly but at a slightly higher rate (6.40%).

Question 3

What is EI (Employment Insurance)?

Accepted Answer

EI is a program that provides temporary income if you lose your job through no fault of your own. You pay a small premium on every paycheque (1.64% in 2026, capped at about $1,077/year). If you are laid off, you can apply for EI benefits to help cover expenses while you search for a new job. EI also covers maternity/parental leave and sickness benefits.

Question 4

What is the difference between marginal and average tax rate?

Accepted Answer

Your average tax rate is the total tax you pay divided by your total income. It tells you what percentage of your entire pay goes to taxes. Your marginal tax rate is the rate applied to your next dollar of income. For example, if your marginal rate is 33%, a $100 raise would result in only $67 extra take-home pay. Your marginal rate is always higher than your average rate because of progressive taxation.

Question 5

Do I need to file taxes if I earn under $15,000?

Accepted Answer

Yes, you should still file even if you owe nothing. The Basic Personal Amount (about $16,129 federally in 2026) means you won't owe federal tax on roughly the first $16,000 of income. However, filing a return ensures you receive benefits like the GST/HST credit, Canada Workers Benefit, and provincial credits. If your employer withheld taxes from your pay, filing gets that money refunded to you.

Question 6

What tax credits are available for students?

Accepted Answer

Students can claim the tuition tax credit for eligible post-secondary tuition fees. You can also carry forward unused tuition credits to future years or transfer up to $5,000 to a parent or grandparent. The Canada Training Credit provides up to $250 per year for training expenses. If you are under 18 and earned income, your parent may also claim the Canada Child Benefit.

Question 7

How is Quebec different for taxes?

Accepted Answer

Quebec has its own provincial tax system separate from the federal one. Instead of CPP, Quebec workers pay into the Quebec Pension Plan (QPP) at 6.40%. Quebec also has the Quebec Parental Insurance Plan (QPIP) at 0.494%, and a lower EI rate (1.32% instead of 1.64%). You file two separate tax returns: one federal and one provincial to Revenu Quebec.

Question 8

When is the tax filing deadline in Canada?

Accepted Answer

For most Canadians, the deadline to file your income tax return is April 30 each year. If you or your spouse are self-employed, the filing deadline is June 15, but any taxes owed are still due by April 30. You can file online using CRA-certified software (many are free for simple returns) or through the CRA's My Account portal.
