Alberta income tax deadline: what you need to know
If you’re an Alberta resident, your personal income tax is filed with the Canada Revenue Agency (CRA). The deadline to file your return and to pay any tax owing is the same as in the rest of Canada, with a small exception for self-employed filers. Here’s the plain‑language guide.
Quick answer
- Most individuals: file and pay your personal income tax by April 30 of the year following the tax year.
- Self-employed individuals: you can file by June 15, but any tax owing is still due by April 30.
- Alberta-specific note: Alberta personal income tax is administered through the CRA, so there isn’t a separate Alberta filing deadline beyond the federal one—the same rules apply in Alberta.

Key filing deadlines
- April 30 (every year):
- The general deadline to file your T1 personal income tax return.
- Any tax you owe for the year is due by this date.
- June 15 (if applicable):
- Filing deadline for self-employed individuals (or if you, your spouse or common-law partner is self-employed).
- Important: even though you have until June 15 to file, you still must pay any tax owed by April 30.
- Example: For the 2023 tax year, most people file by April 30, 2024. If you were self-employed, you could file by June 15, 2024, but any balance owing would still be due by April 30, 2024.

Who this applies to in Alberta
- Alberta residents who file a standard personal income tax return.
- You file the same T1 return with federal and provincial information; no separate Alberta personal tax return is required.
- The provincial portion is calculated as part of the same tax return managed by the CRA.
Note: This guidance is for individuals. If you’re asking about corporate taxes or other Alberta-specific taxes, deadlines can be different and depend on the type of filing.

What happens if you miss the deadline
- Filing late or paying late can result in penalties and interest.
- If you owe taxes and don’t file on time, penalties can apply, and interest accrues on any unpaid balance.
- If you’re due a refund, filing your return late won’t delay your refund once your return is processed.
Tip: If you’re unsure about your filing status or deadline, it’s better to file on time (even if you owe money and need to arrange a payment plan) than to miss the deadline.

How to file (and where to learn more)
- Filing method:
- Online via NETFILE (CRA-certified software) or an approved EFILE service.
- Paper filing is still possible, though electronic filing is faster.
- Where to manage your return:
- CRA’s My Account (for individuals) to view notices, track refunds, and manage payments.
- Alberta-specific information:
- Alberta residents use the CRA-administered process for personal income tax; Alberta’s provincial tax is not filed separately through a different provincial portal for individuals.

Quick tips for beginners
- Mark April 30 in your calendar as the main due date for most years.

- Start gathering documents early: T4 slips, receipts, investment statements, and any RRSP contributions.
- Consider using CRA’s online tools (My Account, NETFILE) for faster processing and easier record-keeping.
- If you expect to owe money, set aside funds ahead of the due date or arrange a payment plan with CRA.
