Where to mail tax return Canada?

Filing your income tax return in Canada means choosing how and where to send it.

The federal tax authority, the Canada Revenue Agency (CRA), accepts paper filings by mail and electronic filing through its NETFILE service.

What Is NETFILE in Canada?

NETFILE is an electronic service provided by the Canada Revenue Agency (CRA) that allows you to send your personal income tax return directly online using certified tax software.

The service opens each tax season and lets you file your return securely without mailing any paper forms.

You must use NETFILE-certified software to prepare your return before submitting it online. You can find the list of certified software on the CRA’s official tax software page.

Once prepared, the software sends your return directly to the CRA through the NETFILE service.

When Does NETFILE Open?

Each year the NETFILE service has a specific start date, usually in late February. For the 2026 tax season, the CRA reopens NETFILE on February 23, 2026 at 6:00 a.m. Eastern Time.

After this date, you can electronically send your 2025 tax return using certified tax software.

Using NETFILE is generally faster than mailing a paper return. The CRA usually processes NETFILE returns more quickly, and you can receive your notice of assessment and refund sooner.

Do I Have to Mail a Paper Return?

You may choose to file a paper return if you are not eligible or able to use NETFILE. Paper filing means printing your completed tax forms and sending them by postal mail to the CRA.

The CRA still accepts paper returns, though processing times can be longer compared with electronic filing.

To file on paper, you need to complete the appropriate income tax and benefit package for the tax year and then mail it to the correct CRA tax centre based on where you live.

Where Do I Mail My Paper Tax Return?

The mailing address for your paper tax return depends on your province or territory of residence as of December 31 of the tax year.

Are There Other CRA Tax Centres?

In addition to the main centres that process personal tax returns, the CRA also has other offices and centres that handle business-related returns and other correspondence.

If you are filing a corporate tax return (T2) or another specific type of return, contact CRA or check the CRA’s official contact pages for the correct address.

What Should I Include When Mailing My Return?

When mailing your paper return, include:

  • Your completed T1 income tax and benefit return and all required schedules
  • All necessary tax slips such as T4, T5, and others
  • Your signature and date on the return
  • Copies of supporting documents only if requested

Send separate envelopes for separate individuals if filing more than one person’s return. Use official CRA addresses and double-check them before sending to ensure correct delivery.

What Happens After I Mail My Return?

Once your paper return is received, the CRA processes it and sends you a Notice of Assessment (NOA).

Processing times for paper filings are typically longer than NETFILE processing times, so expect several weeks after mailing before you receive your NOA or refund.

Should I Choose NETFILE or Mail?

NETFILE is usually faster and more efficient. Filing electronically often results in quicker processing and faster refunds. Paper filing is an option if you cannot file online or prefer a physical submission.

Regardless of method, ensure your return is complete, accurate, and sent to the correct address or submitted through certified software.
