When each spouses in a married couple retire earlier than 65, they most definitely will purchase medical health insurance from the ACA market except they’ve retiree medical health insurance protection or they solely have a brief hole that may be lined by COBRA. When there’s an age distinction between the 2 spouses, the older partner will begin Medicare at 65, leaving the youthful partner in ACA medical health insurance.
Reader Charlie introduced up this actual situation. Each Charlie and his spouse have ACA medical health insurance now. After Charlie turns into eligible for Medicare subsequent 12 months, his 58-year-old spouse will proceed on the ACA plan. Now, after they swap from overlaying each of them on the ACA plan to overlaying only one individual, how will their ACA medical health insurance premiums change?
Will their premiums drop 50%, as a result of they’ll cowl only one individual as an alternative of two? Or really greater than 50%, as a result of the individual coming off the plan, Charlie, is older and costlier to insure?
Will their premiums keep the identical, as a result of ACA premiums are tied to revenue, and their revenue received’t change?
Will their premiums really improve, or drop, however by lower than half, as a result of if it isn’t bizarre and counterintuitive, it wouldn’t make an fascinating topic for a weblog submit?
The reply is — all the above, relying on whether or not they obtain a subsidy and what plan they’ve.
We’re not speaking about premium will increase from the insurance coverage firm or adjustments to the premium tax credit score from adjustments in revenue. Simply altering the variety of individuals lined by an ACA well being plan can have bizarre and sudden results.
No Subsidy
The ACA premium subsidy cliff is scheduled to return in 2026. The latest authorities shutdown didn’t push it out. You received’t obtain any premium subsidy in case your revenue is above 400% of the Federal Poverty Degree (FPL), which is $84,600 in 2026 for a two-person family within the decrease 48 states.
It’s extra intuitive if you don’t qualify for a premium subsidy. Once you pay the total value, insuring two individuals certain prices greater than insuring only one individual. When the older partner begins Medicare, your ACA medical health insurance premiums will drop by half. As a result of it often prices extra to insure an older individual, it’ll fall by barely greater than half.
Subsidy – 2nd Lowest Value Silver Plan
In case your revenue qualifies you for a subsidy, the subsidy is calculated from the premiums for the Second Lowest Value Silver Plan (SLCSP) in your space. If it occurs to be the plan you select, you can be requested to pay a set proportion of your family revenue for that plan. The federal government pays the rest with a premium subsidy. See ACA Well being Insurance coverage Premium Tax Credit score Percentages.
The quantity you’re anticipated to pay towards a second lowest price Silver plan goes by the family dimension and family revenue. It doesn’t matter how many individuals within the family are on the coverage. When one individual goes on Medicare, your family dimension doesn’t change. Nor does your family revenue. Due to this fact, you’re nonetheless anticipated to pay the identical quantity.
Suppose your family revenue is slightly below the utmost that qualifies for the premium tax credit score for a two-person family, and also you select the second lowest price Silver plan in your space. Your web premiums after the subsidy will likely be the identical whether or not you cowl each of you or just one individual. The one distinction is that the premium subsidy turns into smaller when the overall premiums earlier than the subsidy drop by half.
After the older partner begins Medicare, additionally, you will must pay for Medicare Half B and Half D, and probably a Medicare Complement coverage. Your complete spending on well being insurance coverage will improve. However, as a result of the deductible and co-pay on Medicare are decrease than these on an ACA plan, your complete healthcare spending might lower. And since you’ll nonetheless obtain a subsidy if you cowl only one individual, albeit a smaller subsidy than if you cowl two individuals, a subsidy remains to be a subsidy. You’re higher off with a subsidy and never seeing a premium drop than for those who should pay the total value.
Subsidy – Extra Costly Plan
Once you qualify for a premium subsidy and also you select a costlier plan than the second lowest price Silver plan in your space, you pay 100% of the value distinction along with your regular web premium. The formulation in your web premiums is:
Revenue * Relevant Proportion + (full value in your chosen plan – full value for the Second Lowest Value Silver Plan)
When one individual goes off the ACA plan, the value distinction additionally drops by half. Your premiums after the subsidy will go down by the lower within the value distinction.
Suppose you select a Gold plan, and it’s costlier than the second lowest price Silver plan by $500 monthly for 2 individuals. You pay 100% of this $500 value distinction. The worth distinction might change into $240 monthly if you cowl only one individual. Due to this fact you save $260 monthly when the older partner begins Medicare.
Subsidy – Much less Costly Plan
The other occurs if you select a cheaper plan. You obtain 100% of the value distinction as your price financial savings to scale back your regular web premiums. Your web premiums after the subsidy are:
Revenue * Relevant Proportion – (full value for the Second Lowest Value Silver Plan – full value in your chosen plan)
When one individual goes off the ACA plan, your price financial savings drop by half. Your premiums after the subsidy will go up by the lower within the value distinction.
Suppose you select a Bronze plan, and it’s cheaper than the second lowest price Silver plan by $400 monthly for 2 individuals. You obtain 100% of this $400 value distinction. The worth distinction might change into $180 monthly if you cowl only one individual. Due to this fact you lose $220 monthly in price financial savings when the older partner begins Medicare, and your web premiums will rise by $220 monthly.
You pay extra to cowl one individual in a cheaper plan than to cowl two individuals. Such is the punishment for selecting a cheaper plan.
Impact on HSA Contributions
All Bronze ACA plans are eligible for HSA contributions beginning in 2026. Once you select a Bronze plan, you go from household protection to single protection for HSA after one partner begins Medicare, and also you’ll have a decrease HSA contribution restrict. As a result of HSA contributions decrease your Modified Adjusted Gross Revenue (MAGI) for ACA medical health insurance, your MAGI will improve if you contribute much less to the HSA. The next MAGI means a decrease subsidy, or probably shedding the subsidy altogether when your MAGI goes over the 400% FPL cliff.

Right here’s a abstract of all of the eventualities:
| Change in Internet Premiums | |
|---|---|
| No Subsidy | Lower by 50% or extra |
| Subsidy – 2nd Lowest Silver Plan | No change |
| Subsidy – costlier plan | Lower by 50%+ of the value distinction between your plan and the SLCSP |
| Subsidy – cheaper plan | Improve by 50%+ of the value distinction between the SLCSP and your plan, plus the impact from HSA contributions and MAGI |
Charlie and his spouse qualify for a premium subsidy, and so they desire a Bronze plan. Their web ACA plan premiums will go up considerably when Charlie begins Medicare. It’s counterintuitive, however that’s the way it works.
