What is the 90% rule for newcomers to Canada?
Federal non-refundable tax credits are credits that lower the amount of tax you have to pay. (And who wants to pay more tax than they have to?) For instance, the Basic Personal Amount is how much money a person can earn without paying income tax. For 2023, that amount is $15,000 for federal taxes.
If you’ve lived in Canada for only part of the year, that amount is adjusted to match the percentage of the year you were a resident. However, if 90% of your income in the part of the year you were not a resident of Canada is from Canadian sources, you can claim the full Basic Personal Amount (as well as other nonrefundable tax credits).
