Newcomers Guide to Canada Taxes: Complete 2026 Guide

Question: Do I file taxes for a partial year if I arrived mid-year?

Answer: Yes, you must file a Canadian tax return for the year you became a resident, even if you only lived in Canada for part of the year. Your tax return will cover the period from your arrival date to December 31st. You'll only pay Canadian tax on income earned while you were a Canadian resident (not income earned before arriving). Make sure to indicate your entry date on your T1 General form and file as a 'part-year resident' for that first year.

Question: What if I have foreign income from before I arrived in Canada?

Answer: Income earned before you became a Canadian resident is generally not taxable in Canada. However, once you become a resident for tax purposes, you must report worldwide income from that date forward. For example, if you moved to Canada in July, income earned January-June in your home country is not reported on your Canadian return, but income from July-December (both Canadian and foreign) must be reported. Keep documentation showing when you became a resident and where income was earned.

Question: When do I start paying CPP and EI contributions?

Answer: You start paying Canada Pension Plan (CPP) and Employment Insurance (EI) contributions immediately when you begin working in Canada with a valid Social Insurance Number (SIN). Your employer will deduct these from your paycheque automatically. CPP is 5.95% of your employment income (2026 rate, up to maximum) and EI is 1.63%. These contributions make you eligible for CPP retirement benefits later and EI if you lose your job. Self-employed individuals must pay both employee and employer portions of CPP.

Question: How do I get a Social Insurance Number (SIN) as a newcomer?

Answer: Apply for your SIN as soon as you arrive in Canada - you cannot work legally without it. If you're a permanent resident, visit a Service Canada office with your immigration documents (COPR - Confirmation of Permanent Residence) and ID. The SIN is issued immediately and free. If you're on a work permit, you need your work permit document plus ID. Do NOT apply online for your first SIN - in-person is required for newcomers. Once you have your SIN, give it to your employer and keep it safe - you'll need it for tax filing, banking, and government benefits.

Question: What is a tax treaty and how does it affect me?

Answer: Tax treaties are agreements between Canada and other countries to prevent double taxation on the same income. If your home country has a tax treaty with Canada, you may be eligible for reduced tax rates on certain income types or foreign tax credits for taxes already paid abroad. For example, if you earned employment income in your home country before moving to Canada and paid tax there, the treaty may prevent Canada from taxing that same income. Each treaty is different. Consult a tax professional familiar with your specific country's treaty with Canada.

Question: Can I claim Canada Child Benefit (CCB) as a newcomer?

Answer: Yes! You can apply for Canada Child Benefit as soon as you become a resident of Canada and have children under 18. You don't need to wait a full year or be a citizen - permanent residents and some temporary residents qualify immediately. The benefit is income-tested and tax-free (up to $7,800+ per child annually for low-income families). To apply, file your tax return and register for My CRA Account, then apply for CCB online or with Form RC66. Payments start the month after you apply. You must file taxes every year to continue receiving CCB, even if your income is zero.
