Hi, my mother's net income is 24,000 and she has 2000 in medical expenses...I thought she should receive some credits but it shows 0 on line 33099

Thank you for the question.

First, not all medical expenses are eligible; you have to make sure your expenses qualify for favorable tax treatment.

When it comes to eligible medical expenses, you can claim the total amount of eligible medical expenses minus $2,352* or 3% of your net income, .... In the case of your mother, 3% of her net income is $720.
