Where Do You Mail a Tax Return in Canada?
If you file a paper income tax return in Canada, you must mail it to the Canada Revenue Agency tax centre assigned to your province, territory, or specific area of Ontario or Quebec.
The correct address matters. Mailing your return to the wrong CRA tax centre can delay processing, delay your Notice of Assessment, and slow down any refund or benefit-related updates.
As of May 29, 2026, CRA drop boxes are permanently closed. That means paper returns and documents must generally be submitted online where available or mailed to the correct CRA address.
Quick Answer: Where to Mail a Paper Tax Return in Canada?
For most resident individuals, use the CRA tax centre address based on where you lived on December 31 of the tax year.

| Alberta, British Columbia, Manitoba, Saskatchewan, Northwest Territories, or Yukon | Winnipeg Tax Centre, Post Office Box 14001, Station Main, Winnipeg MB R3C 3M3 |
| Ontario: Hamilton, Kitchener, Waterloo, London, Thunder Bay, or Windsor | Winnipeg Tax Centre, Post Office Box 14001, Station Main, Winnipeg MB R3C 3M3 |

What Is a Mailed Tax Return in Canada?
A mailed tax return is a paper version of your income tax and benefit return that you complete, sign, and send to the CRA through Canada Post or another mail service.
Although the CRA encourages most taxpayers to file electronically using NETFILE-certified software, paper filing is still available for many individuals.
A paper tax return usually includes:
- The completed T1 Income Tax and Benefit Return
- Required federal and provincial or territorial forms
- Required schedules
- One copy of each income slip, such as T4, T4A, T5, or other slips
- Any documents the return package specifically asks you to attach
- Your signature and date on the certification section
Do not send original receipts unless the CRA specifically asks for them. Keep receipts and supporting records in your own files.
Filing Deadline for 2025 Tax Returns Filed in 2026
For the 2025 tax year, most individuals had to file their return by April 30, 2026.
If you or your spouse or common-law partner were self-employed in 2025, the filing deadline was June 15, 2026. However, any balance owing was still due by April 30, 2026.
Because both key 2026 deadlines have now passed, anyone who has not filed should file as soon as possible. If tax is owed, filing late may result in penalties and interest.
Filing vs Paying: Do Not Confuse the Two
A common mistake is assuming your tax return and tax payment must be mailed to the same place. They are handled differently.
Mailing a Tax Return
If you are mailing your completed paper tax return, send it to the CRA tax centre listed for your province, territory, or region.
Use the resident individual address table above if you live in Canada.
Mailing a Payment by Cheque
If you owe tax and want to pay by cheque or money order, the CRA uses a separate payment address.
Mail cheque payments to:
Canada Revenue Agency
PO Box 3800 STN A
Sudbury ON P3A 0C3
Make the cheque or money order payable to:
Receiver General for Canada
In the memo field, include your relevant tax number. For individuals, this is usually your Social Insurance Number, Individual Tax Number, or Temporary Taxation Number.
For security and speed, the CRA generally encourages electronic payments instead of mailed cheques.
How to Mail Your Tax Return in Canada?: Step-by-Step
Step 1: Get the Correct Tax Package
Use the income tax package for the tax year you are filing and the province or territory where you lived on December 31 of that year.
For example, if you lived in Ontario on December 31, 2025, use the 2025 Ontario tax package.
Step 2: Complete Every Required Form
Fill in your:
- Full legal name
- Current mailing address
- Social Insurance Number or other CRA tax number
- Date of birth
- Marital status
- Residency information
- Income details
- Deductions and credits
- Direct deposit information, if applicable
Incorrect identification or address details can delay processing and may affect benefit payments or credit payments.
Step 3: Attach Required Slips
For a paper return, include one copy of each required information slip, such as:
- T4 employment income slip
- T4A pension, retirement, annuity, and other income slip
- T5 investment income slip
- T3 trust income slip
- T5007 benefits slip
- Other income slips that apply to your situation
If a slip is missing, do not ignore the income. Use the best available information, such as final pay stubs or online CRA records, and consider including a note explaining what happened.
Step 4: Include Required Schedules
Your tax return may need supporting schedules or forms depending on your claims.
Examples include:
- Federal tax schedules
- Provincial or territorial forms
- Donations and gifts schedule
- Self-employment forms
- Rental income forms
- Tuition-related forms
- Benefit application forms
Only include forms that apply to your tax situation.
Step 5: Do Not Send Original Receipts Unless Asked
Do not automatically mail original receipts for:
- Medical expenses
- Charitable donations
- Moving expenses
- Tuition
- Childcare expenses
- Employment expenses
Keep receipts and supporting documents for at least six years. The CRA may request them later if your return is reviewed.
Step 6: Sign and Date the Return
A paper tax return is not complete unless it is signed and dated.
Before mailing, check the certification section carefully. An unsigned return can be delayed or returned.
Step 7: Mail to the Correct CRA Tax Centre
Use a secure envelope. Consider using a trackable mailing service if you are sending sensitive documents or filing close to a deadline.
Keep a copy of the full return and proof of mailing for your records.
Non-Resident Individuals: Where to Mail a Tax Return
If you are a non-resident individual filing a Canadian tax return, the CRA mailing address may depend on your country of residence or your Canadian connection.
The CRA has also temporarily accepted some non-resident income tax returns by fax because of international mail delays. Always confirm the latest non-resident mailing and fax details on the CRA website before sending documents.

Can You Still Drop Off a Tax Return at the CRA?
No. As of May 29, 2026, CRA drop boxes are permanently closed across Canada.
If you need to submit a paper tax return, you should mail it to the correct CRA tax centre. If you need to submit documents for a CRA request, check whether the CRA allows upload through My Account or another secure online service.
Do not send tax returns or sensitive tax documents by regular email. Email is not a secure method for filing a tax return with the CRA.
Better Alternatives to Mailing a Tax Return
Mailing is still possible, but it is usually slower than electronic filing.
NETFILE
NETFILE allows individuals to send their personal tax return directly to the CRA using certified tax software. Some certified software products are free depending on the taxpayer’s situation.
The NETFILE access code is an 8-character code found on your Notice of Assessment or in your CRA account. It is not mandatory, but it helps confirm identity when filing electronically.
EFILE Through a Tax Professional
Tax preparers and accountants use EFILE to submit returns for clients.
This may be useful if you have:
- Self-employment income
- Rental income
- Capital gains
- Foreign property
- Business income
- Multiple years of unfiled returns
- A deceased person’s return
- A complicated residency situation
Free Tax Clinics
If you have a modest income and a simple tax situation, you may be eligible for help through a free tax clinic. These clinics are hosted by community organizations through the Community Volunteer Income Tax Program, and in Quebec through the Income Tax Assistance – Volunteer Program.
How Long Does a Paper Tax Return Take to Process?
Paper returns take longer than online returns.
The CRA’s tax-season service standard is generally faster for electronically filed returns than paper returns. Paper returns can take weeks longer, especially if information is missing, documents are incomplete, or the return is selected for review.
To avoid delays:
- Use the correct tax year package
- Sign the return
- Attach required slips
- Keep receipts instead of mailing unnecessary originals
- Use the correct CRA tax centre address
- Keep proof of mailing
What Should You Send With a Paper Tax Return?
Use this checklist before sealing your envelope.
Send These
- Completed and signed T1 Income Tax and Benefit Return
- Required federal schedules
- Required provincial or territorial schedules
- One copy of each income slip
- Required forms that support your claims
- Explanatory note if a slip is missing
- Required legal authorization forms, if filing as a representative
Keep These Unless CRA Asks
- Original receipts
- Medical expense receipts
- Donation receipts
- Tuition receipts
- Moving expense receipts
- Childcare receipts
- Bank statements
- Cancelled cheques
- A copy of your completed return
- Notice of Assessment and reassessment documents
Common Mistakes When Mailing a Tax Return
Mailing to the Wrong CRA Address
Always use the address assigned to your province, territory, or Ontario/Quebec region. Do not guess based on the nearest office.
Sending a Cheque to the Tax Return Address
If paying by cheque, use the CRA payment mailing address, not necessarily the same tax centre used for the return.
Forgetting to Sign the Return
Unsigned paper returns can be delayed or returned.
Sending Original Receipts
Keep original receipts unless the CRA specifically requests them.
Waiting Until the Deadline
Mail delivery time matters. If you file close to the deadline, use a service that provides tracking or proof of mailing.
Filing Late When You Owe Tax
If you owe money and file late, penalties and interest may apply. Even if you cannot pay in full, filing as soon as possible may reduce additional charges.
Special Note for Quebec Residents
Quebec residents generally deal with both the CRA and Revenu Québec.
The CRA handles the federal return, while Revenu Québec handles the Quebec provincial return. If you lived in Quebec on December 31 of the tax year, check both agencies’ requirements before filing.
For your federal paper T1 return, use the CRA mailing address assigned to your Quebec region. For the Quebec provincial return, follow Revenu Québec’s instructions.
Before You Mail: Final Checklist
Before mailing your return, confirm that:
- You used the correct tax year package
- Your name, SIN, and address are correct
- Your marital status is correct
- All income has been reported
- All required slips are included
- Required schedules are included
- The return is signed and dated
- Your cheque, if any, is payable to Receiver General for Canada
- Your tax number is included in the cheque memo field
- You are mailing the return to the correct CRA tax centre

Conclusion
Knowing where to mail a tax return in Canada is essential if you choose to file on paper. The CRA assigns tax centre addresses based on where you live, and sending your return to the wrong location can delay processing.
For 2026, the biggest update is that CRA drop boxes are now permanently closed. Paper returns must be mailed to the correct CRA tax centre, while payments by cheque must be sent to the CRA payment address in Sudbury.
For faster processing, consider NETFILE or a certified tax professional. If you still prefer paper filing, use the correct address table, attach only what is required, sign your return, and keep copies of your records for at least six years.
FAQs About Where to Mail Tax Return Canada
Can I mail documents to the CRA?
Yes. The CRA still accepts many paper tax returns and tax documents by mail. However, you must send them to the correct CRA address. If the CRA asks for documents, check the request letter carefully because it may include a specific mailing address or online upload option.
Can I drop off my tax return at a CRA office?
No. CRA drop boxes permanently closed on May 29, 2026. After that date, taxpayers should use online services where available or mail paper documents to the correct CRA address.
Do I need to file a tax return in Quebec?
If you lived in Quebec on December 31 and are required to file, you may need to file both a federal return with the CRA and a Quebec provincial return with Revenu Québec. Quebec has its own provincial income tax system, so residents should check both CRA and Revenu Québec requirements.
What happens if I mail my tax return to the wrong CRA address?
It may still be redirected internally, but it can cause processing delays. To avoid problems, use the CRA address assigned to your province, territory, or region before mailing.
Should I send receipts with my paper tax return?
Only send receipts or documents that the tax return package specifically tells you to attach. In most cases, you should keep receipts for at least six years in case the CRA asks to review them later.
Where do I mail a cheque payment to the CRA?
Mail cheque payments to:
Canada Revenue Agency
PO Box 3800 STN A
Sudbury ON P3A 0C3
Make cheques payable to Receiver General for Canada and include your tax number in the memo field.
Is mailing a tax return slower than filing online?
Yes. Paper returns generally take longer to process than electronically filed returns. NETFILE or EFILE is usually faster if you are eligible to file electronically.
What is the penalty for filing a personal tax return late?
If you file late and have a balance owing, the CRA may charge a late-filing penalty and interest. The standard late-filing penalty for 2025 returns is 5% of the balance owing, plus 1% for each full month late, up to 12 months. Repeated late filing can result in a higher penalty.
What is the penalty for not filing T4A slips?
This applies to businesses, payers, or issuers, not ordinary recipients of a T4A slip. CRA penalties for late T4A information returns depend on the number of slips filed late and may include a minimum penalty. If you are a payer, check the CRA’s latest T4A filing guidance or speak with a payroll professional.
Can I email my tax return to the CRA?
No. Do not email your tax return or sensitive tax documents to the CRA. Use CRA secure online services, NETFILE, EFILE, or mail where applicable.
