Dear Liz: We’re living on a very tight budget and often have to put groceries and unexpected expenses on a credit card that’s in my husband’s name only. I have no personal income. My husband is on Medicare, but I’m too young to qualify and need to find low- or no-cost healthcare, (I haven’t had any insurance since 2007.) They are using my husband’s total income and coming up with high rates that are supposed to be lowered by tax credit, but we don’t pay income tax because our income is too low. Should they be using what the IRS considers our income to be? Or could I apply using my zero personal income?

Answer: By “they,” you presumably mean a health insurance marketplace where you shopped for policies offered by private insurers. HealthCare.gov is the federal marketplace and many states, including California, offer their own. When you shop for a policy through a marketplace, you can qualify for subsidies that can dramatically lower the cost of your coverage.

This subsidy, also known as a premium tax credit, is based on your household income, not your individual income. The tax credit is refundable, which means you get it whether or not you owe federal income taxes, and you can opt to have the subsidy paid in advance to the health insurer to lower your premiums. You don’t have to wait until you file your taxes to get the money back.

You’ll want to act quickly, though, because the penalty for not having coverage is rising. The penalty for 2016 is the greater of $695 per adult or 2.5% of income. You still have a short window to avoid that hit: The enrollment deadline is Jan. 31.
