When you move back in with your parents, you may lose some tax credits and deductions but could gain access to others depending on your age, income, and family situation. The main tax impact involves changes to your dependant status, potential loss of rent deductions, and eligibility for new credits based on shared household expenses. Your parents may also benefit from claiming you as a dependant if you meet CRA rules, though this creates important coordination between your returns. Moving back home typically triggers one major shift: you're no longer paying rent as an independent household. In Canada, rent itself is not tax-deductible for personal use housing. However, the move can affect several tax credits you may have claimed when living independently. If you were claiming the Canada Housing Benefit (CHB) or other rental assistance credits, these generally phase out when your rent expense decreases. Your parents may also want to claim you as an eligible dependant on their tax return if you don't have a spouse or common-law partner and your net income falls below the threshold (around $15,705 for the 2025 tax year).
Yes, if you're under 18, or if you're 18+ with a net income below the threshold (approximately $15,705 for 2025), and you live with them for the entire year without a spouse or common-law partner. Your parents can claim the eligible dependant credit on their tax return. You and your parents should coordinate filing to avoid both claiming the same credit.
Generally yes. Rental housing benefit credits (like the Canada Housing Benefit) apply only when you pay rent. Once you move in with your parents, your rent expense drops to zero, so these credits no longer apply. Check your provincial website to see if there are any special circumstances that might allow you to keep claiming.
Possibly, if you have a dedicated workspace and you're self-employed or required by your employer to work from home. You'd calculate a reasonable proportion of shared household expenses (utilities, rent, property tax) as a deduction. Discuss the arrangement with your parents and keep documentation of the arrangement and any shared costs.
Shared household expenses cannot be claimed as rent deductions on your return, because you don't own the home. Your parents may claim property tax and home heating rebates. If you contribute money toward utilities or internet, treat it as personal living expenses, not tax-deductible payments. Only claim amounts if you have a legitimate business use (home office) supported by documentation.
There's no tax rule against it, but it's a personal family decision. Contributing to groceries, utilities, or other household costs doesn't affect your tax return or your parents' ability to claim you as a dependant. Just make sure any contributions are not structured as rent payments, which could create confusion with the CRA.
