💊 CRA Medical Expenses (Lines 33099 & 33199): Complete Tax Credit Guide

Maximize your tax refund by correctly claiming eligible medical expenses on your Canadian tax return.

📌 What Are Lines 33099 and 33199?

The Canada Revenue Agency (CRA) allows you to claim eligible medical expenses as a non-refundable tax credit on your tax return.

Line 33099: Expenses for yourself, your spouse/common-law partner, and children under 18
Line 33199: Expenses for other dependants (e.g., adult children, parents, relatives)

These lines are part of Step 5 – Federal tax on your return.

👥 Who Can You Claim For?

✔ Line 33099

Yourself
Your spouse or common-law partner
Your children under 18

✔ Line 33199

Children 18+
Parents, grandparents
Siblings, aunts, uncles, nieces, nephews

These dependants must rely on you for support and generally be Canadian residents during the year.

💰 How Much Can You Claim?

You can claim medical expenses that exceed a minimum threshold:

✔ 3% of net income OR
✔ A fixed amount (e.g. $2,834 — whichever is lower)

Only the portion above this threshold is eligible for the tax credit.

📊 How to Calculate (Simple Steps)

Add all eligible medical expenses
Calculate 3% of net income
Compare with the fixed threshold
Subtract the lower amount
Claim the remaining balance

Tip: The lower-income spouse should usually claim the expenses for maximum benefit.
