If your partner is your dependant you can claim tax credits like the spousal amount on line 30300, and the Canada caregiver amount on line 30425.
To claim these (and other) credits, answer all the questions that appear in the Your Partner section. If your returns are linked, you should also complete their entire return.
Keep in mind:
- you might need to Check & Optimize your return for certain credits to appear, and
- you cannot add your partner to the Dependants section.
