Calculate your eligible medical expenses and estimated federal + provincial tax credit under CRA rules.
Scenario: Richard ($2,500), Pauline ($2,000), Jen age 16 ($1,800), Rob age 19 ($1,300).
Line 33099 (self, spouse, children under 18):
Richard + Pauline + Jen = $6,300
Pauline's net income = $55,000 → 3% = $1,650 (less than $2,834)
Claim = $6,300 − $1,650 = $4,650
Line 33199 (Rob, age 19): Rob's expenses ($1,300) minus threshold based on Rob's net income → separate calculation.
Each dependant has their OWN threshold based on their net income. Add one row per dependant.
Claim the incremental cost: cost of gluten-free product − cost of similar gluten product.
The METC is a non-refundable federal tax credit for eligible medical expenses you paid during the year. It is calculated as the amount of eligible expenses exceeding the lesser of 3% of your net income or $2,834 (2025), multiplied by 14.5%.
The 2025 threshold is the lesser of 3% of your net income or $2,834. The threshold is applied separately for Line 33099 (based on your income) and Line 33199 (based on each dependant's income).
Line 33099: Yourself, your spouse/common-law partner, and your children under 18. Line 33199: Other dependants — children 18+, grandchildren, parents, grandparents, brothers, sisters, uncles, aunts, nephews, and nieces who depended on you for support.
You can claim expenses paid during any 12 consecutive months ending in 2025, as long as those expenses were not claimed by anyone else for 2024. Strategically choosing a period that spans two calendar years can capture more expenses.
If you claim full-time nursing home care as medical expenses, you cannot also claim the Disability Amount for the same person. You can claim the Disability Amount plus up to $10,000 of attendant care salaries (Ontario: $17,627).
The refundable medical expense supplement (Line 45200) is available to working individuals with low income and high medical expenses. It is refundable — you receive it even if you owe no tax.
Common ineligible expenses include over-the-counter medications, cosmetic surgery, athletic club fees, organic food, and anything reimbursed by insurance. See the "Ineligible Expenses" accordion above for the full list.
Québec has its own medical expense rules on Line 381 using family income, plus a separate refundable credit on Line 462. Use the provincial portion of your Québec return for accurate calculation.
