1. Does she need to file her own tax? 2. She is listed as dependant and when I file my tax it asks if she made any income.. what do I put there since she did not file?
This CRA webpage has information on who is required to file a tax return: https://www.canada.ca/en/services/taxes/income-tax/personal-income-tax/who-should-file-tax.html
If she doesn't file a return you can enter her T4 income minus the deductions listed on the T4.
