Should I File Taxes as a Couple or Separately? Canada 2026

Canada doesn’t have a joint tax return: every individual files their own return. Being married or common-law still ties the two returns together, because each one reports the other partner’s income and several credits can be claimed by either partner. This page covers how couples file, what you report about your partner, and which partner claims which credit. For the rest of the process, see the guide to filing a tax return in Canada.

There is no “joint return” in Canada

Unlike the United States, Canadians do not have the option to file a joint return with a spouse or common-law partner. Each person files their own T1 General return separately. However, both returns must be coordinated because:

• You must disclose your spouse/partner’s net income on your return
• Many credits and deductions are calculated based on family net income (both partners combined)
• Several income-splitting opportunities exist that require claiming on the correct partner’s return

These rules apply to married couples and to common-law partners. Whether CRA treats you as common-law (the 12-month and child tests) is explained in am I common-law for tax purposes?

Disclosing your spouse’s income

When you file, you must report your spouse’s or common-law partner’s net income on your return (Line 23600 of your T1). This figure feeds into several credits, most importantly the spouse or common-law partner amount.

CRA cross-references both returns, so both partners’ returns should be filed to avoid delays.

Credits that depend on your partner

• Spouse or common-law partner amount (Line 30300): one partner can claim a federal credit when the other partner’s net income is low. How the amount is worked out is covered in the guide to the tax benefits of getting married.
• Age amount transfer: From the year you turn 65, you can claim the federal age amount: $9,208 for 2026, reduced by 15% of net income above $46,432. If your spouse qualifies for it but their income is too low to use all of it, they can transfer the unused portion to you.
• Disability tax credit transfer: if your spouse has an eligible disability but can’t use the full disability tax credit due to low income, the unused credit can be transferred to you.

Who claims which credit

Medical expenses

Either partner can claim combined medical expenses for both spouses on one return. Only expenses above a threshold of 3% of the claimant’s net income (or a fixed dollar cap, whichever is less) count, so the claim usually goes further on the lower earner’s return. The current threshold and eligible expenses are in the medical expense tax credit guide.

Charitable donations

Charitable donations made by both spouses can be combined and claimed by either partner. The federal credit applies one rate to the first $200 and another to the rest, so pooling donations on one return means the first-$200 tier applies once instead of on each partner’s return. The rates are in the charitable donation tax credit calculator.

Other deductions

Claimed by the higher-income partner:

• RRSP deductions (at their higher marginal rate, which saves more tax per dollar)
• Home office expenses (if both work from home, split by days worked from home)

Claimed by the lower-income partner:

• Child care expenses: under the CRA rule these must be claimed by the lower-income partner, with exceptions for the higher earner in cases of incapacity or full-time student status
• Medical expenses (claim on the return where they exceed the 3% income threshold)

Income splitting between partners

• Pension income splitting: eligible pension income can be split with your spouse on your returns through a joint election, with no money changing hands. Eligibility and the election form are covered in pension income splitting in Canada.
• Spousal RRSP: the higher earner contributes in the lower earner’s name and deducts the contribution; withdrawals are later taxed to the annuitant. See should I contribute to a spousal RRSP?
• Investment income: income from money gifted to a lower-income spouse is generally taxed back to the giver under the attribution rules. A loan charged at the CRA prescribed interest rate is the usual way to shift investment income legally.
• Rental income: if rental property is jointly owned, income is split proportionally by ownership percentage. Ownership is easiest to support when it is documented (title shows percentage or a co-tenancy agreement exists).

Marital status changes

Once you’re married or common-law, the spousal credits and rules above apply, and benefits such as the Canada Child Benefit and the Canada Groceries and Essentials Benefit (formerly the GST/HST credit) are recalculated on family income. Not updating your status can lead to retroactive reassessment of those payments; the steps for telling CRA are in how to update your marital status with CRA.

Frequently asked questions

Can we file our tax returns at different times? Yes. There’s no requirement for both partners to file simultaneously. However, several credits (spousal amount, pension splitting) require both partners’ information to be calculated correctly. Filing together or close together reduces the chance of errors.

We’re both high earners. Are there any tax benefits to being a couple? Fewer, but still some. You can split eligible pension income after 65 (which can meaningfully reduce tax if one partner has a DB pension). You can combine charitable donations. And whichever partner is higher on medical expenses in a given year gets a better credit result.

My partner doesn’t have a SIN or isn’t a Canadian resident. Do I still have to disclose their income? CRA asks for your spouse’s net income even if they’re a non-resident or don’t have a SIN. Report what you know; CRA will process accordingly. If your partner has no Canadian income, their net income is typically zero.

What if we separated during the tax year? Use your marital status as of December 31. If you were separated for 90+ consecutive days by December 31, you file as “separated” for the full year. Credits are recalculated accordingly. If you reunited before December 31, you’re still considered married/common-law.
