The future of the Affordable Care Act is uncertain, with Republicans in Congress vowing to swiftly repeal the law, albeit with a substantial delay — as much as four years — before the repeal is actually implemented. And while we don’t know exactly what will be introduced as a replacement for the ACA, there have been numerous proposals over the last few years that give us insight into what’s likely to be included in the replacement.

Our Repeal & Replace section has more details in terms of what’s likely to happen, and how subsidies might end up being structured a few years down the road. But for 2017, nothing will change in terms of premium subsidies. If you’re already enrolled in a plan with a subsidy, the subsidy will continue throughout the year, as long as you remain eligible for it.

Open enrollment for 2017 continues through the end of January, with subsidies available for those who meet the eligibility criteria. If you’re eligible for a subsidy, or think you might be, it’s essential that you enroll in a plan through the exchange by January 31. Subsidies aren’t available if you get your coverage outside the exchange, and if you wait until after the end of January, you’ll need a qualifying event (with proof) in order to enroll in coverage for 2017.

Use our subsidy calculator. Get started.

As of March 2016, there were 9.4 million people receiving premium subsidies through the exchanges. That’s almost 85 percent of everyone who was enrolled in the exchanges at that point. For enrollees across all 50 states and DC, those subsidies averaged $291 per month in 2016. That’s a significant portion of the $386 per month average premium (before subsidies) for people who got coverage through Healthcare.gov.

In short, the subsidies are a significant part of the “affordable” in Affordable Care Act. With each successive open enrollment period, awareness of the law’s premium tax credits (subsidies) has continued to grow. But many Americans may still be wondering, “Am I eligible to receive a premium subsidy – and if so, what should I expect?”

Subsidies based on the cost of Silver plans

Middle-income and low-income people buying coverage in the exchanges are eligible for government subsidies that come in the form of tax credits. Most eligible enrollees take those tax credits in advance, paid directly to their health insurance carrier each month to offset the amount of premiums due.

But you can also pay full price throughout the year for a plan through the exchange, and then claim your subsidy as a lump sum when you file your taxes. (Subsidy reconciliation is completed when you file taxes, using form 8962. If the subsidy you receive during the year is too high, you’ll pay back some or all of it when you file taxes; if it was too low – or if you didn’t receive an advance subsidy at all during the year – you’ll get the balance of the tax credit when your return is processed).

Premium subsidies are available to exchange enrollees if their income is between 100 percent and 400 percent of the federal poverty level. (Off-exchange enrollments are not eligible for subsidies, regardless of income). In states that have expanded Medicaid under the ACA, Medicaid is available to enrollees with incomes up to 138 percent of the poverty level, and subsidies are not available below that threshold.

In all states, the upper limit for subsidy eligibility is 400 percent of the poverty level. For plans purchased during the 2017 open enrollment period (November 1, 2016 to January 31, 2017), that upper subsidy threshold is $97,200/year for a family of four; subsidy availability extends well into the middle class. (Some people with incomes under 400 percent of the poverty level don’t receive subsidies simply because the unsubsidized cost of coverage in their area is under the threshold established by the ACA).

Subsidies are tied to the cost of the second-least expensive Silver plan in your area (ie, the benchmark plan). The architects of the Affordable Care Act (ACA) wanted to make sure that people who must buy their own insurance can afford that benchmark Silver plan, even in regions where health care is extremely expensive. So knowing the price of a Silver plan in your region is key to calculating the size of your subsidy.

In October 2016, just prior to the start of open enrollment for 2017, HHS published a report showing the average change in benchmark premiums across all the states that use HealthCare.gov, along with several of the state-based exchanges. The average benchmark premium increase was 22 percent. Although that was alarmingly high, it’s important to keep in mind that when benchmark premiums rise, subsidies increase too, offsetting some or all of the premium increase.

The enrollment software will automatically calculate your subsidy, but many enrollees are curious about how the subsidy amount is determined, so here are the details:

What exactly is a Silver plan?

In the exchanges, insurers offer Bronze, Silver, Gold and Platinum plans. (Catastrophic plans are also available to young adults and people with hardship exemptions, although subsidies are not available on catastrophic plans). All must cover the ten benefits that Congress decided are “essential” (outpatient care, emergency services, hospitalization, maternity and newborn care, mental health and substance abuse disorder services, behavioral health treatment, prescription drugs, rehabilitative services, laboratory services, preventative care and pediatric services, including oral and vision care for children.)

All plans also must offer free preventive care, and they cannot refuse to cover you or charge you more because you suffer from a pre-existing condition.

The only major difference between the four tiers is that Bronze and Silver plans have lower premiums, with higher co-pays and deductibles – up to a maximum of $7,150 in out-of-pocket costs in 2017. After that, the insurer pays for all essential benefits.

Gold and Platinum plans’ premiums are higher, but total out-of-pocket exposure on those plans is often lower ($7,150 is the maximum individual out-of-pocket exposure on any plan in 2017, but Gold and Platinum plans often have lower caps on out-of-pocket costs). Silver plans pay roughly 70 percent of enrollees’ expected healthcare costs, and have premiums that are higher than Bronze plans, but lower than Gold plans (note that “expected healthcare costs” is in relation to the average costs for the entire population covered by the plan, including those with very high healthcare costs; it does not apply to each individual insured).

Who is eligible for a subsidy?

If your employer offers “affordable” comprehensive insurance, you’re not eligible to receive a subsidy in the exchange. Note that the affordability test only applies to coverage for the employee; the cost to add dependents to the plan is not taken into consideration. But if the employee’s coverage is considered affordable, the dependents are not eligible for premium subsidies in the exchange – this is known as the family glitch.

If your employer offers affordable coverage that provides minimum value, you already are receiving a subsidy from your employer in the form of pre-tax health insurance benefits and an employer contribution to your premiums. The exchanges offer subsidized health insurance benefits to the self-employed, the unemployed, and employees who work for a company that does not offer affordable health benefits.

How to calculate your subsidy in four easy steps

The size of your subsidy is based on your income, the number of people in your household, and the price of the benchmark Silver plan in your region.

To calculate the size of your subsidy:


1) Use this table to find out whether your income and household size makes you eligible for a subsidy in 2017 (these numbers are based on the 2016 federal poverty guidelines. Since open enrollment for 2017 began in 2016, these numbers will be used throughout 2017).

For instance, as the table indicates, a family of three with household income up to $80,360, and a family of five with income up to $113,640, are eligible to receive a tax credit for 2017, depending on the cost of a Silver plan in their area.

Percent of Federal Poverty Level (FPL)
Household Size 100% 133% 150% 200% 300% 400%
1 $11,880 $15,800 $17,820 $23,760 $35,640 $47,520
2 $16,020 $21,307 $24,030 $32,040 $48,060 $64,080
3 $20,160 $26,813 $30,240 $40,320 $60,480 $80,640
4 $24,300 $32,319 $36,450 $48,600 $72,900 $97,200
5 $28,440 $37,825 $42,660 $56,880 $85,320 $113,760
6 $32,580 $43,331 $48,870 $65,160 $97,740 $130,320
For each additional person, add $4,160 $5,533 $6,240 $8,320 $12,480 $16,640

2) Find out how much the Affordable Care Act expects you to contribute to the cost of your insurance by consulting Table 2. The expected contribution is adjusted slightly each year – these percentages are for 2017. If you decide not to buy insurance, you won’t have to pay a premium, but you will have to pay a penalty that will be at least $695 per uninsured adult in 2017 (there was no inflation adjustment for 2017, so this is the same as it was in 2016), or 2.5 percent of taxable household income above the filing threshold, whichever is higher. And the penalty does not purchase anything—you wouldn’t have coverage if you needed medical care.

If you earn Your expected contribution is
Up to 133% of FPL 2.04% of your income
133%-150% of FPL 3.06%-4.08% of your income
150%-200% of FPL 4.08%-6.43% of your income
200%-250% of FPL 6.43%-8.21% of your income
250%-300% of FPL 8.21%-9.69% of your income
300%-400% of FPL 9.69% of your income

The subsidy will make up the difference between the amount an individual is expected to contribute (based on income) and the actual cost of the area’s second-lowest-cost silver plan.


3) Determine out how much a benchmark Silver plan costs in the area where you live. You can scroll through the available quotes in your state’s exchange and see what the second-lowest-cost silver plan’s premium would be for you and your family, or you can call the exchange. It’s important to note that the benchmark plan changes from one year to another; carrier A might have the second-lowest-cost Silver plan one year, but due to premium fluctuations, carrier B might take over that spot the following year.


4) See Table 2. Subtract the amount that you are expected to contribute (based on your income) from the cost of your benchmark silver plan. For instance, let’s say your silver plan costs $3,000 a year, and you are expected to contribute $1,000. You will receive a subsidy of $2,000


Sample calculations

Rick is 27 and lives in Alabama. In Alabama in 2017, the average benchmark Silver plan costs $384 a month for a 27-year-old or $4,608 annually (the exact amount for Rick would depend on his zip code, but for the sake of this example, we’re just using the state-wide average).

If Rick earns $23,760 (or 200 percent of FPL) he would be expected to kick in 6.43 percent of his income, or $1,528 toward his insurance. (0.0643 x $23,760 = $1,528)

To calculate his subsidy, he just needs to subtract $1,528 (the amount he kicks in) from $4,608 (the cost of the plan). His subsidy will be $3,080.

[Note that you can also calculate your expected contribution percentage if your income is somewhere in the middle of one of the ranges shown in Table 2. Here’s how it works].

If Rick’s 27-year-old cousin Alice, earns the same amount as Rick, but lives in New Hampshire – where health care is less expensive – she’ll pay the same amount for the benchmark plan, but her subsidy won’t need to be as large. In New Hampshire, the average benchmark premium for a 27 year-old is $219 per month, or $2,628 for the year.

If Alice also earned $23,760 (200 percent of the FPL) the government would expect her to spend 6.43 percent of her income on coverage, just like her cousin in Alabama (remember, the expected contribution is tied to income, not the underlying cost of the plan). So she, too, would contribute $1,528. But because the benchmark plan in Burlington costs $2,628, her subsidy would be just $1,100. ($2,628 — $1,528 = $1,100).

Since Rick and Alice earn the same amount, they pay the same in after-subsidy costs for the benchmark plan: $1,528 for the year. This is based on their income — not their age, health status, or location. But Rick’s subsidy has to be larger than Alice’s, because the unsubsidized cost of his plan is so much more, due to his location.

If Rick and Alice were younger, the silver plan would be less expensive and their subsidies would be smaller. If they were older, the Silver plan would be more expensive, and their subsidies would be higher.

The idea behind the subsidies is to level the playing field and bring average premiums to a middle ground for everyone who has the same general level of income. So at the same income level, an older person will receive a higher subsidy than a younger person, but they’ll both ultimately pay the same price for the benchmark plan.
