Final answer:
The limit for the deduction of medical expenses is 10% of AGI for most taxpayers, but temporarily set at 7.5% for taxpayers who are 65 or older.
Step-by-step explanation:
The limit for the deduction of medical expenses is 10% of AGI for most taxpayers. However, for taxpayers who are 65 years of age or older, the limit is temporarily set at 7.5% of AGI until December 31, 2020. This means that you can only deduct medical expenses that exceed either 10% or 7.5% of your AGI, depending on your age.
For example, if your AGI is $50,000 and you are under 65 years of age, you can only deduct medical expenses that exceed $5,000 (10% of $50,000). If you are 65 years of age or older, you can deduct medical expenses that exceed $3,750 (7.5% of $50,000).
