Can I claim medical expenses such as the purchase of prescription glasses for my 21 year old son who is away from home attending university?
Only if at some time in the year your 21 year old son was dependent upon you for support. In order to calculate how much can be claimed on behalf of your dependant, your claim must be reduced by the amount by which the dependant’s net income exceeds $7,231 multiplied by 4. For example, if your son’s net income was $7,300, the claim would be calculated as: the total medical expense minus ($7,300-7,231) x 4. So if the cost of his glasses was $300, the amount that you could claim would be: $300 minus ($7,300-7,231) x 4 = $24.
