Where to mail your tax return as a non-resident or deemed resident

If you live in the United States, United Kingdom, France, Netherlands, or Denmark, mail your non-resident T1 return to the Winnipeg Tax Centre, PO Box 14001, Station Main, Winnipeg MB R3C 3M3, Canada. From every other country, mail it to the Sudbury Tax Centre, 1050 Notre Dame Avenue, Sudbury ON P3A 5C2, Canada. The address depends on where you live now — not on where in Canada you used to live.

Key facts

  • Only five countries route to Winnipeg: the USA, UK, France, the Netherlands, and Denmark. Every other country on the planet files in Sudbury.
  • Your current country of residence decides the address — not the Canadian province you left or where your income came from.
  • The CRA considers a return filed on time if received or postmarked on or before the due date, so keep dated proof of mailing when filing internationally.
  • Write "CANADA" as the last line of the address — foreign postal services need the destination country spelled out.
  • Mailing from abroad can take weeks and you cannot walk into a Canada Post office overseas. PostPal lets you upload your return online from anywhere and mails it domestically within Canada.
  • PostPal deposits your letter with Canada Post the next business day — order early for deadline filings.

How to mail it, step by step

  1. 1

    Identify which tax centre takes your return

    Check your current country of residence. The USA, UK, France, the Netherlands, and Denmark map to the Winnipeg Tax Centre (PO Box 14001, Station Main, Winnipeg MB R3C 3M3). Every other country maps to the Sudbury Tax Centre (1050 Notre Dame Avenue, Sudbury ON P3A 5C2).

  2. 2

    Use the non-resident tax package

    Non-residents and deemed residents file with the Income Tax and Benefit Package for Non-Residents and Deemed Residents of Canada, not a provincial package. Complete it, attach the required slips, and sign it — an unsigned return is not considered filed.

  3. 3

    Decide how to get it to Canada

    International post is slow and hard to track. Instead of mailing a paper envelope across an ocean, upload your completed return to PostPal — we print it in Canada and send it to the right tax centre through Canada Post, $6 flat.

  4. 4

    Keep dated proof for the deadline

    The postmark date is what proves on-time filing. PostPal emails you a dated confirmation when your letter is deposited with Canada Post, which is far easier to obtain than a foreign postmark receipt.

Common questions

I am a Canadian living in Australia — where do I mail my return?

To the Sudbury Tax Centre, 1050 Notre Dame Avenue, Sudbury ON P3A 5C2, Canada. Only filers living in the USA, UK, France, the Netherlands, or Denmark mail to Winnipeg; residents of every other country, including Australia, mail to Sudbury.

Does it matter which province I lived in before leaving Canada?

No. For non-residents and deemed residents, the mailing address is set by the country you live in now. Whether you left from British Columbia or Nova Scotia, the rule is the same: Winnipeg for the five listed countries, Sudbury for everywhere else.

How do I mail a CRA return if I cannot access Canada Post from abroad?

You do not have to use your local foreign postal service. Upload your completed T1 to PostPal from anywhere in the world; we print it in Canada, put it in an envelope, and hand it to Canada Post the next business day for $6 — no international postage, no customs delays.

What counts as on time when I file from another country?

The CRA considers a return filed on time if it is received or postmarked on or before the due date. A domestic Canada Post postmark obtained through PostPal is dated in Canada, which avoids any ambiguity about foreign postmarks and transit times.

Am I a non-resident or a deemed resident — and does the address change?

Non-residents have cut residential ties with Canada; deemed residents (such as some government employees posted abroad or people who stayed in Canada 183 days or more without establishing residency) are taxed as if resident. Both groups use the same two addresses based on the country they live in.

Should I write CANADA on the envelope?

Yes, if you mail from abroad — the destination country must appear as the last line so foreign sorting facilities route it correctly. If you use PostPal, the letter is mailed within Canada, so this issue disappears entirely.
