How can I “prove” that I purchased medical insurance in order to write it off?

Sand Dunes: How can I “prove” that I purchased medical insurance in order to write it off?
I itemize and writing off a portion of the $ 6k I paid in insurance premiums would help. I am self-employed and, because decent individual health insurance is nearly extinct, I got my insurance through my domestic partner’s employer. How can I “prove” that I paid for this health insurance? Do I need to have a $ 6k check written to my domestic partner that says “for health insurance” on it or am I pretty much screwed? (Which I’ve been learning is fairly typical for self-employed persons.)

I think you’re screwed. My guess is the IRS would see your partner as paying the premium. In any event, you can only deduct medical expenses that are in excess of 7.5% of your AGI.

The answer is the same as you asked before. The costs must be 1)more than 7.5% of your adjusted gross income, 2) you must be eligible to itemize so your itemized expenses must be more than your standard deduction, this is not a write off on your schedule C, 3) it cannot be a pretax deduction on your domestic partners insurance. If it is pretax then it is not deductible at all.
