Your First Canadian Tax Return as a Newcomer: A Practical Guide

Summary

For individuals who have recently arrived in Canada, understanding when tax residency begins and what filing obligations follow is the critical first step in navigating the Canadian tax system.

The Canada Revenue Agency (CRA) considers you a newcomer for the first year you are a resident of Canada for income tax purposes. For most newcomers, residency begins on the first day they live in Canada, once they have established significant residential ties — such as a home, a spouse, or dependants residing in Canada.

As a Canadian tax resident, you are taxed on your worldwide income from the date you become a resident, not for the full calendar year. This means you report only the Canadian-source and foreign-source income earned after your residency start date. For assets you already owned before becoming a resident, the cost basis is set at their fair market value on the day you became a resident — a crucial detail that will affect capital gains calculations when those assets are later sold.

An important relief provision for newcomers concerns Form T1135, the Foreign Income Verification Statement. Under the CRA's published guidance, an individual does not have to file Form T1135 for the tax year in which they first become a resident of Canada. The T1135 filing threshold is triggered when the total cost amount of specified foreign property exceeds $100,000 CAD at any time during the year. While the first year is exempt, from the second year onward, newcomers must use the fair market value at the time of immigration as the cost basis when determining whether the $100,000 threshold has been crossed.

Newcomers can also apply for Canadian benefit and credit payments — including the GST/HST credit and the Canada Child Benefit (CCB) — even before filing their first tax return. The CRA provides a dedicated application pathway for this purpose.

Our Take

The first year of Canadian tax residency can be overwhelming, particularly for clients who also hold U.S. tax status. We recommend that newcomers take several steps as soon as possible after arrival. First, establish a clear residency start date — this anchors your worldwide income reporting period. Second, inventory all foreign assets held before immigration and document their fair market value on that date, both for future capital gains purposes and for T1135 readiness starting in year two. Third, use the first-year T1135 exemption window to organize your global asset records while the filing pressure is off.

For clients who must also file U.S. returns, a key point to remember is that becoming a Canadian tax resident does not end U.S. filing obligations for U.S. citizens and green card holders. Both countries' reporting timelines and disclosure requirements must be coordinated. A common practical challenge is the TFSA — while tax-free in Canada, it is not recognized as a tax-exempt account for U.S. purposes, and its income remains reportable to the IRS. We strongly advise consulting a cross-border tax professional in your first year of Canadian residency to build a comprehensive compliance plan.
