A Spouse or Common-law Partner Affects How You File Your Tax Return

Even though each person must still file separately, here's what you need to know:

You Must Report Your Spouse’s Information

Even though you each file an individual return, the CRA requires you to:

  • Indicate your spouse’s name, SIN, and net income

  • Include this info even if they had no income

This allows the CRA to properly calculate income-tested benefits and credits, like the GST/HST credit or Canada Child Benefit (CCB).

Claim Spousal Tax Credits

You may be eligible to claim:

  • Spousal amount (line 30300): If your spouse’s net income is less than $15,705 (2024 threshold), you may claim up to that amount.

  • Transferable credits: Your spouse can transfer unused credits (e.g., age amount, disability amount, tuition) to reduce your taxes.

Impact on Benefits and Credits

The CRA uses family income to determine:

  • GST/HST credit

  • Canada Child Benefit (CCB)

  • Age amount or Guaranteed Income Supplement (GIS) eligibility

If only one of you files, CRA may deny or delay benefits without the other’s return.

Income Splitting Opportunities

While not directly tied to filing, some tax-saving strategies like pension income splitting or spousal RRSPs must be reported properly on your returns.

You Must Update Your Status

If your marital status changed during the year (e.g., you got married, separated, or became common-law), you must:

  • Indicate the exact date of the change

  • Notify CRA within one month
