There is only a tax credit for rent in certain provinces:
If you live in Ontario, search for “rent” in the search box and select the Ontario Trillium Benefit section. Claim any relevant credits and report your rent in that section.
If you live in Manitoba, indicate that you qualify for the Manitoba Education Property Tax Credit in the About You section. Find this under the Manitoba Tax Credits heading.
If you live in an eligible dwelling in Québec you may be entitled to the Solidarity Tax Credit. Report the amount from your RL-31 in the Solidarity Tax Credit section.
You may also claim your rent if you are self-employed or if you are allowed to claim employment expenses (i.e., you have a signed T2200 from your employer). In this case, enter your rent as an “Other Expense” where you claim your use-of-home expenses.
