I am on Medicare and Social Security. My wife is self employed and needs insurance from the state exchange. How do we figure our household income?

Q. I am on Medicare and Social Security, my wife recently became self-employed and needs health insurance from the state exchange, as she’s not yet old enough to qualify for Medicare. How do we figure our household income? Does my social security count toward household income, even though I will not be buying insurance?

A. For the purpose of determining subsidy eligibility, here’s the formula that’s used to calculate modified adjusted gross income (MAGI). MAGI is based on household income, even if only one spouse is applying for a policy in the exchange.

Keep in mind that subsidy eligibility is a function of income related to the poverty level. Although your total household income is obviously higher than your wife’s income alone, the poverty level for a household of two is also higher than the poverty level for a household of one.

What are the income limits for ACA subsidy eligibility?

For 2020 coverage, the upper income limit for a household of one to receive subsidies is $49,960. (Here’s how household income is calculated under the ACA.) For a household of two, it’s $67,640.

So while your income is counted when determining whether she’ll qualify for a subsidy, you’re also counted as part of the household when determining how the household’s income compares with the poverty level.

The exchange will look to see what percentage of your total household income is necessary to cover the full-price cost of the benchmark plan for your wife. If it’s more than the percentage of income that people are expected to pay for their coverage, she’ll qualify for a premium subsidy. But the amount that you pay for your Medicare coverage will not be counted; they will only look at how much your wife’s policy costs in relation to your total household income. Here are some examples of how differing family sizes affect total subsidy amounts, as it can sometimes be a bit counter-intuitive.

In order to qualify for a subsidy, married applicants must file joint tax returns. If your wife experienced a qualifying event (for example, losing her employer-sponsored plan when she became self-employed), she can enroll in the exchange during the special enrollment period triggered by her qualifying event. If not, she’ll have access to individual market plans when open enrollment begins again on November 1.

Your wife can use your most recently filed tax return to provide income information to the exchange. But if your household income has changed significantly as a result of her recent self-employment, she can instead provide the exchange with an estimated projection of your household income, and then provide updates to the exchange later on if her income changes again.

For any year that she receives advance premium tax credits (subsidies) during the year (or if she pays full price through the exchange but ends up with a household income that makes her subsidy-eligible), she’ll need to use Form 8962 to reconcile her subsidy on your joint tax return.

Regarding the above situation, it is similar to my own, this is the first time I am seeking a credit on I believe to be overpayment of premiums, but when my husband is filing his taxes showing our earnings which are within the threshold for a couple it shows no refund, I am not sure why. Although I’ve checked on the marketplace it says different when I fill out the information as a reference. Is this because my husband is on Medicare so I am being seen as only one and not entitled to a lower premium or refund after all.

When you’re a household of two, the premium for just yourself is compared with your total household income to determine if you qualify for a subsidy (and they also use the poverty level for a household of two, so potential subsidy eligibility does extend to a higher income in that situation). It’s based on keeping your premium in the exchange (in this case, for just yourself) at the percentage of your household income that’s considered affordable. (you can see more about those percentages here: )
So yes, the subsidy is much smaller if only one spouse is enrolling through the exchange, because the pre-subsidy premium for just one person is less than it would be for two people. Have you completed Form 8962 yet? It will show you the price of the benchmark plan in your area, the price of the plan you purchased, and the amount of premium subsidy — if any — that you should receive.

my wife and I went on the ACA in the Nov of 2020 when I retired. In June of 2022 she will turn 65 and go on Medicare. I will only be 57 at that time and on the ACA by myself. When she switches over to Medicare does that trigger a qualifying event for me so I can go on a different plan or do I have to wait until open enrollment to switch plans? Once she goes on Medicare, does the money we are paying for Medicare part B, Medigap and a part D plan still count as part of our MAGI or do we subtract that amount when calculating our income for the ACA for me? How does the fact that she will be on the ACA for six months and medicare for six months affect us? Ideally, once she goes on the ACA I would like to go onto a high deductible plan. Right now we are on a very low deductible plan because she has had numerous health problems for years. Me, on the other hand, I generally go to my doctor once per year for my annual wellness physical and I do not have any health issues.

There is not a special enrollment period for that specific circumstance, but if your eligibility for a premium subsidy changes at the same time, that would trigger a special enrollment period:
Unfortunately, the money you’ll be paying for Medicare coverage would not be taken into account when your subsidy eligibility for your own plan is calculated. Here’s more about how that works: (it can be quite counterintuitive)
In terms of the mid-year plan change, if you’re receiving a premium subsidy, the subsidy for your wife would end when she switched to Medicare, and this will be reflected on the 1095-A that you receive from the marketplace. Although you’re unlikely to be able to switch plans for yourself at that point (and would have to wait until open enrollment that fall), keep in mind that it’s possible to put yourselves on two different plans as of the start of 2022, if that’s your preference. You can still receive a premium subsidy for your household, even if there are multiple marketplace plans for the same household.

We have a family of three. If all three enroll, the premium after the subsidy is less than if one or even two of us join. That’s right. The household income is the same, but premium is double if two join instead of three.

So next year when he goes on Medicare, the two remaining family members will pay double for ACA, and he’ll pay for Part B plus a premium for his health plan. In total our costs will go up 500%.

We expect to pay added costs for him, but we should expect to pay less for the remaining two.

Our income hasn’t gone up, so why should two family members pay more than three?

Premium subsidies in the marketplace only account for how the marketplace premium (for whichever household members are enrolling) compares with the total household income. The cost to obtain non-marketplace coverage for one household member (for example, someone who transitions to Medicare) is not taken into consideration.

If the household is enrolled in the benchmark plan (the second-lowest-cost silver plan, upon which subsidy amounts are based), their after-subsidy premium should remain no more than it was when all three family members were on the marketplace plan, since that’s capped as a percentage of total household income. The subsidy will be considerably smaller, however, since the pre-subsidy total premium for two members is lower than it would have been for three members.

But if the household is applying the subsidy to a lower-cost plan, they may very well see a considerable increase in the after-subsidy premium when one family member transitions to Medicare and the marketplace subsidy decreases.

As an example, consider a couple, age 63 and 64, living in Chicago and earning $60,000 in 2021. They qualify for a $1,245/month subsidy, and the benchmark plan costs $360/month after that subsidy is applied. But they can get the cheapest available plan for about $8/month after the subsidy.

If we now assume it’s a year later and they are 64 and 65 with the older spouse eligible for Medicare, most of the numbers are different — except the after-subsidy cost for the benchmark plan for the 64-year-old spouse will still be the same $360/month. But the subsidy is much smaller ($449/month), and it doesn’t go as far toward bringing down the cost of the lowest-priced plan, which will be $180/month (versus just $8/month when both spouses were enrolled together).

You can use our subsidy calculator to see more examples of how this works:

But the general idea is that the cost of the benchmark plan in the marketplace will be capped at the same amount for a household both before and after a family member transitions to Medicare. But the cost of the Medicare premiums isn’t taken into consideration when accounting for how much the household is spending on premiums, and the cost of a non-benchmark plan could vary quite a bit when the subsidy decreases following the removal of one family member from the marketplace plan.
