What married couples and common-law partners should know
Many couples in Canada wonder whether they should file their income tax returns together or separately.
Should you combine your income? Can your spouse’s income affect your refund? What happens if one spouse has no income?
Let’s answer these questions in a simple way.
1. Do Couples File One Joint Tax Return in Canada?
No. Married couples and common-law partners generally file separate individual tax returns.
Each person reports their own income, deductions, and tax credits.
However, you can prepare both tax returns together. This allows you to consider information about both spouses when applying relevant tax rules.
Example
Sarah earns $45,000, and her husband John earns $60,000.
Sarah files her own tax return, and John files his own.
Their tax preparer can prepare both returns together to review applicable credits, transfers, and family-related information.
Remember: Preparing returns together does not mean submitting one joint tax return.
2. Does My Spouse’s Income Affect My Taxes?
Yes, your spouse’s income can affect certain tax credits and government benefits.
However, you generally do not pay income tax on your spouse’s salary.
Each person reports their own income, while certain benefits and credits use information about both partners.
Example
Sarah earns $35,000, and John earns $80,000.
Their individual tax returns are calculated based on their own income. However, their combined family income may affect eligibility for certain income-tested benefits.
This is why reporting your marital status and your spouse’s information accurately is important.
3. Why Is Your Marital Status Important?
CRA recognizes different marital statuses, including married and common-law.
Your marital status can affect certain tax and benefit calculations.
You should update the CRA when your marital status changes, such as when you get married or become separated.
Important: CRA has specific rules for determining when someone becomes common-law or separated. You should follow those rules rather than choosing a status based on personal preference.
4. Can One Spouse Claim Amounts for the Other?
In certain situations, one spouse may qualify for tax amounts involving the other spouse.
Examples include:
- Spouse or common-law partner amount: May be available when the spouse’s income meets the applicable conditions.
- Medical expenses: Couples may need to consider which spouse should claim eligible medical expenses.
- Tuition amounts: Certain unused tuition amounts may be transferable.
- Pension income splitting: Available for eligible pension income under specific rules.
Not every tax credit can be transferred, and eligibility depends on the circumstances.
Preparing both returns together helps your tax preparer review these possibilities.
5. What If One Spouse Has No Income?
A spouse with no income may still need to file a tax return, depending on their circumstances.
Filing can be important for accessing certain benefits and credits.
In some situations, the spouse with income may also qualify for a tax amount involving their partner.
Don’t assume that a spouse with no income should automatically be excluded from the tax filing process.
6. What If One Spouse Is Self-Employed?
If one spouse operates a business, their business income and eligible expenses must be reported on their own tax return.
For example, if John operates a handyman business and Sarah works for an employer:
- John reports his business income and eligible expenses.
- Sarah reports her employment income.
- Both returns can be prepared together.
Self-employed individuals should also review their GST/HST obligations, where applicable, and keep proper records.
7. Common Mistakes Couples Should Avoid
Here are a few things to remember:
1. Assuming couples file one joint return
Canada generally requires separate individual returns.
2. Forgetting to update marital status
Changes should be reported according to CRA requirements.
3. Assuming your spouse’s income is always combined with yours
Each person generally reports their own income, although some calculations use family income.
4. Assuming preparing returns together guarantees a bigger refund
Tax results depend on individual circumstances and applicable rules.
Final Thoughts
Filing taxes as a couple in Canada doesn’t mean submitting one joint return.
Each spouse files individually, but preparing both returns together can help ensure that relevant tax credits, transfers, and family information are considered.
Whether you are married, common-law, newly separated, or self-employed, understanding these rules can help you prepare your tax return accurately.
