Tax Year Prior to 2020: Is premiums for long term care insurance deductible

[KarenL2]

Usually, yes.  They are entered in the Medical Expenses area.  There will be blue text and Learn More links that will provide helpful information for you.

For medical expenses to be deducted on the tax return, you must itemize deductions on Schedule A, and your unreimbursed medical expenses must exceed 10 percent of your adjusted gross income (AGI).   Then, you can only deduct the amount by which your unreimbursed medical expenses exceed this 10 percent threshold (7.5% of AGI for age 65 and older until 2017). However, some states allow the full deduction, even if you don't have enough for your federal taxes.
