I am self-employed and purchase my spouse's health insurance on the Federal Marketplace with no subsidy. Can I claim 100% of her health insurance premiums?

Yes, you can. You will enter it under business expenses: Insurance.

The deduction is generally limited to your net profit from your self-employment (or your self-employed earnings as a partner or your paid wages as a shareholder in an S corporation).
