Who We Help

Who Needs a Canadian T1 Return?

Start with your residence history and income sources. The situations below are reasons to review filing requirements, not a conclusion that every person needs the same returns.

Situations to Discuss

Canadians who lived or worked in Canada for any part of the year
US citizens or Green Card holders with Canadian income or residency
Canadians who moved to the US and need a departure return
Dual citizens with income in both Canada and the US
Canadians with RRSP, TFSA, or Canadian pension income
US residents receiving Canadian rental income
Canadians returning to Canada after US residency

Canadian Accounts and US Reporting

A Canadian account label does not determine its US tax treatment. Review the account agreement, investments and income before deciding which US tax and information returns apply. FBAR and Form 8938 have separate requirements; foreign-trust reporting requires its own classification and exception review.

RRSP Treaty Elections

Form 8891 is obsolete. Under Revenue Procedure 2014-55, eligible individuals receive automatic US tax deferral on undistributed income in qualifying Canadian retirement plans. Eligibility depends on US return filing and prior reporting of plan income and distributions; FBAR and Form 8938 obligations remain separate.

For preparation involving both countries, work with a US-Canada cross-border tax accountant and discuss the scope of the engagement.

Departure Returns

Becoming a Canadian non-resident can trigger a deemed sale of certain property at fair market value. Exceptions include Canadian real estate and specified registered plans. Review residential ties, the departure date and the assets involved before determining your reporting obligations.

Canadian T1 Tax Return Filing Requirements

For the 2025 Canadian return, filing reasons include tax owing, a CRA request, claiming a refund and maintaining benefit payments. Other triggers also apply. Review the CRA checklist for your circumstances rather than assuming citizenship alone determines whether you must file.

For 2025 returns, most people had an April 30, 2026 filing and payment deadline. The filing deadline was June 15, 2026 if you or your spouse or common-law partner carried on a business, except where business expenditures related mostly to a tax shelter investment. Payment remained due April 30. Special situations require a separate deadline check.

Before preparation, gather income slips, prior returns, CRA notices, residence dates and relevant account records. Agree which returns and information forms are included, how documents will be provided and who will submit each filing. Confirm the available filing method for the return concerned.

Canadian Benefits and RRSP Deduction Room

Benefit eligibility depends on income, family circumstances and other conditions. Eligible newcomers may receive some payments before filing their first return; annual filing by both partners, where applicable, is needed to maintain payments. Check the current CRA rules instead of relying on an undated maximum benefit amount.

The 2026 RRSP dollar limit is CAD 33,810. Your personal deduction limit also reflects prior-year earned income, unused deduction room and applicable pension adjustments; check your CRA deduction-limit statement before deciding how much to contribute or deduct.

Bring statements and contribution records for your Canadian registered accounts to the preparation discussion. Ask which Canadian deductions, US income items and information returns need review before making account-specific decisions.

T1 Filing for US-Canada Dual Citizens

US citizens and resident aliens abroad generally apply the same US filing rules as those living in the United States. Income, filing status and age affect the return requirement. Check Canadian obligations separately; dual citizenship does not by itself establish that both returns are required every year.

Qualifying foreign income taxes may support a US foreign tax credit, commonly claimed on Form 1116. Taxes on income excluded from US gross income cannot also support that credit. Do not assume Canadian tax paid will eliminate the US balance; review the income and applicable credit rules.

US returns report amounts in US dollars. IRS guidance generally uses the exchange rate when an item is received, paid or accrued, and accepts consistently used posted rates. Keep transaction dates and conversion records; do not assume one annual average rate is suitable for every income item or information return.

T1 Canada Return FAQs

What is a T1 Canadian tax return?

The T1 is Canada's individual income tax and benefit return. Review the CRA filing checklist for your income, tax owing, benefits and other filing triggers.

Do US citizens living in Canada need to file both a T1 and a US return?

Check each country separately. US income, age and filing status affect the US return requirement, while Canadian filing triggers depend on your circumstances. Citizenship alone does not establish that both returns are required every year.

What is a Canadian departure return?

In the year you become a non-resident, report worldwide income for the Canadian-resident portion and review Canadian-source income afterward. A deemed disposition can apply to certain property, with exceptions. Moving abroad does not by itself settle tax residency.

When is the T1 filing deadline?

For most 2025 returns, filing and payment were due April 30, 2026. Qualifying self-employed filers had until June 15 to file, with payment still due April 30. Check special circumstances and the rules for the actual tax year.

How are RRSPs treated for US tax purposes?

Do TFSAs need to be reported to the US?

Review FBAR and Form 8938 separately against their filing requirements. Account structure and transactions also matter for any foreign-trust reporting analysis; do not infer a Form 3520 obligation from the TFSA label alone.

Can I discuss both my Canadian T1 and US return?

Use the introductory call to explain the work you need in each country. Confirm the returns, tax years, preparation responsibilities and fees in the engagement scope before paid work begins.
