How to Prepare for a 2027 ACA Premium Increase in July 2026: What the Preliminary Rate Filings Mean and 6 Moves to Make Before Open Enrollment

July 15 was the deadline for ACA marketplace insurers to file their proposed 2027 premium rates with state regulators. Early analyses of those filings are not comforting: across roughly 77 insurers in 16 states and D.C. that had submitted by mid-July, the median proposed increase is about 14%, with the bulk of requests landing between 10% and 20%. Twenty carriers have asked for more than 20%. This comes on top of an average 26% sticker-price jump for 2026 that translated into roughly a 58% net premium spike for subsidized enrollees after the enhanced tax credits expired.

Two questions matter right now. First: what will your actual 2027 premium look like, not the headline? Second: what can you do between mid-July and Open Enrollment on November 1 to keep the number in your budget? This guide walks through both.

Rate filings are proposals, not final numbers. Every summer, insurers submit them to state departments of insurance, which then review the assumptions, sometimes ask for changes, and approve final rates in late summer or early fall. The public gets a preview because rate-filing dockets are public in most states — sites like Rate Review at healthcare.gov, RateReview.org, and state DOI portals let you look up your carrier's requested increase for your county.

The headline number — a 14% median increase for 2027 — masks a lot of variation:

• Metal level matters. Silver plans, especially the benchmark second-cheapest silver, often see different pricing than bronze or gold because of how silver-loading (see below) affects insurer pricing strategy.
• Geography matters. Rural single-carrier counties tend to see the biggest increases; urban counties with three or more competing insurers usually see smaller ones.
• Age matters. ACA premiums are age-rated at a maximum 3-to-1 ratio, so a 60-year-old's percentage increase and dollar increase are typically the largest.
• Tobacco use matters. Up to 50% surcharge (or state-specific rules) can amplify the increase.

From 2021 through 2025, the American Rescue Plan and Inflation Reduction Act pushed ACA subsidies well past their original design. Two features stood out: the 400% federal poverty level "subsidy cliff" was removed, and the sliding-scale share of income you owed for the benchmark plan was cut. A household at 150% of FPL paid $0 for a benchmark plan; a household above 400% of FPL was capped at 8.5% of income for it. Those enhancements expired December 31, 2025, and Congress did not renew them for 2026 or 2027.

The result: net premiums for subsidized enrollees jumped an average of 58% in 2026 even though gross premiums rose "only" about 26%. If 2027 gross premiums rise another 14%, subsidized enrollees will feel the increase on top of a much higher starting base — and households just above 400% of FPL will pay the full sticker price with no subsidy at all.

If you're on the edge of the cliff, run your projected 2027 modified adjusted gross income now. Our ACA Subsidy Calculator can show you where your household's MAGI falls in the FPL bands, whether you'll receive any subsidy in 2027, and how much staying below 400% of FPL is worth in your county. If you're close, small legal MAGI adjustments (HSA contributions, traditional IRA contributions if eligible, self-employed retirement plans) can shift a household from "no subsidy" to a meaningful subsidy.

For subsidized enrollees, the plan that matters is not your plan — it's the second-cheapest silver plan in your rating area. That plan is the benchmark, and it sets the size of your Advance Premium Tax Credit (APTC). Your APTC equals the cost of the benchmark plan minus your "expected contribution" based on income. You can spend that APTC on any metal-level plan.

When insurers price 2027 plans, most will "silver-load" — concentrate the cost of unfunded Cost-Sharing Reductions (CSR) into silver premiums. That inflates the benchmark, which inflates your APTC, which typically makes bronze and gold plans a better deal than a non-benchmark silver. So the same person, same income, same county can pay significantly different net premiums for 2027 depending on which plan they select relative to the benchmark.

You can't stop the rate increase, but you can control your net premium and your exposure. Here is the pre-Open-Enrollment checklist for July through October 2026.

You are approaching Medicare eligibility in 2027

If you turn 65 in 2027, your Initial Enrollment Period for Medicare is a seven-month window around your 65th birthday. Your marketplace plan and any APTC end when Medicare Part A begins. Coordinate the transition carefully to avoid a coverage gap, a Part B late-enrollment penalty, or an HSA contribution problem tied to Medicare's six-month lookback. For the details, see our companion guide on the HSA-Medicare six-month lookback trap.

You lost enhanced-subsidy coverage in 2026 and have not re-enrolled

Some enrollees dropped coverage when net premiums jumped in January 2026. If that is you, and your income has since changed, the 2027 numbers may look different. Even if you are still uninsured, you can enroll during Open Enrollment for 2027 coverage without needing a Special Enrollment Period.

You are a small-business owner or self-employed

Consider whether an ICHRA, QSEHRA, or a Solo 401(k)/SEP-IRA-driven MAGI cut serves you better than the marketplace directly. For ICHRA specifics, see our guide on what to do if your employer offered an ICHRA.

You may qualify for Medicaid or CHIP in 2027

If your income has dropped below 138% of FPL (in expansion states) or your state's threshold otherwise, you may be eligible for Medicaid, which has no premium and much lower cost sharing than any marketplace plan. Marketplace enrollment automatically checks Medicaid eligibility. If you were enrolled in Medicaid and unwound, our losing-Medicaid guide walks through the transition.

Between now and late summer, three things will move:

1. State regulators will review filings. Some states (New York, California, Rhode Island, others) actively negotiate rates down; others largely defer. Expect final rates to be slightly lower than the July requests in most active-review states.
2. Congress may act on subsidies. Bipartisan proposals to restore some form of enhanced ACA subsidies before Open Enrollment surface periodically. Watch legislative news through September. Anything passed and signed before enrollment begins would materially change the net-premium math.
3. Insurers may enter or exit specific counties. Some carriers reduce their footprint when rates are cut; others enter counties where competitors leave. This can change your benchmark and shift plan availability. Final plan lists publish alongside final rates.

The one thing you can control now is your income planning, your provider audit, and your Open Enrollment readiness. The move that saves the most money for most households is not "picking the right plan" — it's shopping every year rather than auto-renewing. In a year of shifting benchmarks and shifting subsidies, that is doubly true for 2027.

A double-digit ACA rate increase is likely for 2027, layered on top of the biggest one-year net-premium jump the marketplace has seen since 2018. But "rate increase" and "your bill" are not the same number. Your income, your subsidy, your benchmark, and your plan choice all sit between the two. Use the four months between now and Open Enrollment to project your MAGI honestly, lower it if you can, check your carrier's proposed rate, and pre-shop your plan options as soon as the 2027 marketplace opens.
