T4 box 10: province of employment

Your employer issues a T4 for every job you had during the year, by the end of February.

What it is: The province or territory where you reported for work, shown as a two-letter code such as ON or BC. ZZ means you worked outside Canada.
Where it goes on your return: Nothing to enter. It's for the CRA. Your provincial tax is based on where you lived on December 31, not this box.

If you moved during the year, the province in box 10 can differ from your home province, and that's normal.
Your employer withholds provincial tax based on box 10, so moving between provinces can leave you with a refund or a balance owing.
