Should you and your spouse file taxes together or separately?
Unlike other countries such as the United States, Canadian tax rules don’t allow spouses or common-laws to file joint income tax returns. Each Canadian files their own tax return and indicates their marital status and name of their significant other on the return.
A coupled return means that each spouse files an individual return, but the returns are prepared together. If you can split or combine any of the above credits, a coupled return is your best bet.
What happens when one spouse earns more income than the other?
Couples where one individual earns significantly more money than the other, often pay more income tax than they would if their incomes were equal.
So it’s important for the spouse with the higher income to maximize deductions to reduce paying taxes at a higher rate.
The CRA doesn’t always allow deductions to be passed on to the spouse. For example, if you or your spouse spends money on child care, it may be possible to deduct some of those expenses from your income when filing your federal income tax return. But with certain exceptions, the person with the lower income must claim the child care expenses.
Are there any tax benefits to being married
The good news is that you can now transfer some credits to your spouse (if you don’t use them first) and pool others. Specifically you can:
Transfer unused credits. If you file as married or common law and have some unused credits, these can be transferred to your spouse or partner. These include tuition amount, age amount, disability amount, and pension income amount.
不過你哋要beware of the 90% rule.

Newcomer to Canada—why do I need to report my foreign-source income?
This only applies if you immigrated to Canada in the year.
You must report your foreign-source income from the part of the year before you immigrated to Canada because this amount is used to determine if you meet the 90% rule (see below).
When you meet the 90% rule, you can claim the full amount of all Canadian tax credits, even though you didn’t live here all year. If you don’t meet the 90% rule, several credits must be pro-rated based on your date of entry.
You meet the 90% rule if, in the part of the year before you moved to Canada:
you didn’t earn any foreign-source income, or
90% or more of your income was Canadian-sourced.
