The federal poverty level is an income threshold published each January by the Department of Health and Human Services. For ACA Marketplace enrollments, FPL is the denominator behind every subsidy calculation: APTC eligibility, CSR tier, and the Medicaid boundary all depend on the ratio of a household's projected MAGI to the FPL amount for their household size.
Key Takeaways
- HHS publishes FPL guidelines each January. The ACA uses these to determine APTC eligibility and CSR tiers for the same plan year.
- APTC eligibility begins at 100% FPL in non-expansion states. In Medicaid expansion states, Medicaid covers adults up to 138% FPL, and Marketplace APTC applies above that.
- CSR lowers cost-sharing on Silver plans for households at 100% to 250% FPL. Three distinct CSR tiers exist within that range, with meaningful actuarial value differences at the 150%, 200%, and 250% boundaries.
- The 400% FPL subsidy cliff was eliminated by the American Rescue Plan. Above 400% FPL, APTC is calculated to cap the Silver benchmark premium at 8.5% of household income.
- ACA income is MAGI, not gross revenue. A sole proprietor with $80,000 in gross revenue and $25,000 in business deductions has a $55,000 MAGI, not $80,000. Getting this right at intake determines the correct FPL percentage and subsidy amount.
What FPL is and where it comes from
HHS has published poverty guidelines since the 1960s, derived originally from Social Security Administration subsistence income research. Today the guidelines are adjusted each January to reflect inflation. The ACA uses the guidelines published for the current year to calculate APTC eligibility and CSR tiers for the same plan year.
Alaska and Hawaii have separate, higher FPL tables. Every other state and DC use the 48 contiguous states table. Clients who recently moved between Alaska or Hawaii and the lower 48 may see their FPL percentage shift even if their income did not change.
FPL thresholds and what they trigger
The ACA uses specific FPL percentage boundaries to determine eligibility and the depth of subsidy. Knowing which tier applies before the quote call is what determines which plans are worth showing first.
| FPL range | APTC eligible? | CSR tier | Notes |
|---|---|---|---|
| Below 100% | No | None | Non-expansion states: coverage gap. Expansion states: Medicaid eligible. |
| 100% to 150% | Yes (non-expansion states only at 100% to 138%) | 94% AV Silver | Highest CSR tier. Deductibles and OOP max significantly reduced on Silver. |
| 151% to 200% | Yes | 87% AV Silver | Strong CSR tier. Silver plan cost comparison is essential in this band. |
| 201% to 250% | Yes | 73% AV Silver | CSR still applies on Silver. Bronze vs Silver math still often favors Silver. |
| 251% to 400% | Yes | None | APTC applies on any metal tier. No CSR. Bronze vs Silver depends on utilization. |
| Above 400% | Yes (enhanced subsidy cap) | None | Silver benchmark premium capped at 8.5% of income after APTC. Phases down as income rises. |
FPL in dollar terms
Knowing that 200% FPL puts a household in the 87% actuarial value CSR tier is useful. Knowing what annual income produces 200% FPL for a given household size is what makes the intake question meaningful. The table below shows approximate dollar thresholds for the 48 contiguous states and DC. HHS updates these figures annually. Verify current amounts at aspe.hhs.gov before using them in client conversations or enrollment submissions.
| Household size | 100% FPL | 150% FPL | 200% FPL | 250% FPL | 400% FPL |
|---|---|---|---|---|---|
| 1 | ~$16,100 | ~$24,150 | ~$32,200 | ~$40,250 | ~$64,400 |
| 2 | ~$21,800 | ~$32,700 | ~$43,600 | ~$54,500 | ~$87,200 |
| 3 | ~$27,500 | ~$41,250 | ~$55,000 | ~$68,750 | ~$110,000 |
| 4 | ~$33,200 | ~$49,800 | ~$66,400 | ~$83,000 | ~$132,800 |
Approximate figures for illustrative purposes, 48 contiguous states and DC. HHS adjusts FPL guidelines annually. Verify current thresholds at aspe.hhs.gov before using these amounts in client conversations or enrollment submissions.
To illustrate: a household of 3 with projected MAGI of $55,000 and a 2026 FPL guideline of approximately $27,500 for a 3-person household calculates as 200% FPL. That places the household at the 87% actuarial value CSR tier boundary on Silver plans. Income a few hundred dollars lower shifts the household deeper into the 87% tier. A few hundred dollars higher pushes it toward the 73% tier. The CSR difference between those two tiers is material: out-of-pocket maximum and deductible change, which changes the plan comparison.
Below 100% FPL and the coverage gap
The ACA was designed with Medicaid expansion covering adults up to 138% FPL, so the Marketplace subsidy floor starts at 100% FPL. Adults below 100% FPL were intended to access Medicaid. In the 11 states that had not expanded Medicaid as of mid-2026, this creates a gap: adults between roughly 0% and 100% FPL in those states are not eligible for Medicaid under the non-expanded rules, and they are not eligible for APTC because the Marketplace floor is 100% FPL.
A client who reports $13,000 income in a non-expansion state as a single adult falls into this gap. No APTC, no Medicaid. The broker can explain the situation and check whether any state-specific programs exist, but there is no Marketplace subsidy available at that income level in those states. For the full coverage gap picture, including which states have not expanded and what limited options remain, read the ACA coverage gap in non-expansion states.
Above 400% FPL: what the American Rescue Plan changed
Before 2021, APTC phased out entirely at 400% FPL. A household one dollar above 400% FPL received no subsidy. The American Rescue Plan Act of 2021 removed this cliff and replaced it with a sliding cap: the Silver benchmark plan cannot cost more than 8.5% of household income after APTC at any income level. This extended subsidy eligibility to households significantly above 400% FPL.
That enhancement was extended through the Inflation Reduction Act and remained in effect for the 2026 plan year. A single adult with $90,000 income would pay no more than 8.5% of $90,000, or about $637 per month, for the Silver benchmark plan in their rating area. If the gross Silver benchmark premium in their area is lower than that cap, no APTC is applied. If the gross premium is higher, APTC covers the difference. The ACA subsidy calculator handles the APTC math at any income level, including above 400% FPL, using live CMS Marketplace data.
Using FPL in the quote conversation
Most quoting platforms, including Quotit and QuoteTurbo, display the calculated FPL percentage on the quote screen. The number is there. What the broker adds is the explanation of what it means for which plans the client should consider.
Three things to confirm before opening the plan list:
Confirm projected MAGI, not current pay. A W-2 employee who started a new job at $55,000 mid-year may have $30,000 in actual earnings by December 31. The correct figure at enrollment is projected annual MAGI for the full plan year. Self-employed clients should project net income after deductions, not gross revenue.
Flag income near CSR boundaries. A household of 2 projecting $43,500 income is just above the 200% FPL threshold. Adjusting the income projection down by $500 could shift the household into the higher 87% actuarial value CSR tier. The premium difference on that Silver plan tier shift can be several hundred dollars per year in cost-sharing. For how CSR tiers interact with plan selection, read ACA subsidy eligibility and the 2026 income limits.
Advise clients to report income changes mid-year. A raise, a side business launch, or a one-time payment mid-year can shift the FPL percentage and change the APTC amount. Reporting the change to Healthcare.gov adjusts APTC forward and reduces the Form 8962 surprise in February. The SLCSP benchmark for the year does not change; the monthly APTC does.
FAQ
Common questions brokers and clients ask about the federal poverty level and how it affects ACA subsidies.
What does FPL stand for and who publishes it?
FPL stands for federal poverty level. The Department of Health and Human Services publishes the annual poverty guidelines, typically in January. The ACA uses these guidelines to determine APTC eligibility and CSR tiers for the same plan year. The official tables are posted at aspe.hhs.gov. Alaska and Hawaii have separate, higher FPL guidelines.
How do I calculate a client's FPL percentage?
Divide the client's projected annual MAGI by the FPL dollar amount for their household size from the current HHS guidelines. A household of 2 with $40,000 MAGI and a 2026 FPL guideline of approximately $21,800 for a household of 2 calculates as roughly 183% FPL, which places the household in the 87% actuarial value CSR tier on Silver plans. Use projected annual income for the full plan year, not current monthly income multiplied by 12.
What is MAGI and how is it different from gross income?
Modified Adjusted Gross Income for ACA purposes starts with adjusted gross income on the federal tax return and adds back non-taxable Social Security benefits, tax-exempt interest, and excluded foreign income. For W-2 clients, MAGI is close to gross income. For self-employed clients, MAGI is net business income after deductions. A sole proprietor with $80,000 gross revenue and $25,000 in deductions has $55,000 MAGI for ACA purposes.
What happens if a client's income changes mid-year?
APTC is calculated on projected annual income at enrollment. If actual income differs from the projection, the IRS reconciles the difference on Form 8962 at tax time. Clients who earned more than projected repay some or all of the excess APTC. Clients who earned less may receive an additional credit. Brokers should advise clients to report mid-year income changes to Healthcare.gov so the monthly APTC adjusts forward rather than waiting for the annual reconciliation.
Does the FPL change every year?
Yes. HHS adjusts the poverty guidelines annually, typically to track inflation. A client who was just above a CSR threshold in one plan year could fall below it the next year if the FPL increase outpaces their income growth, which shifts their CSR tier and plan math. Verify the current FPL table at aspe.hhs.gov before running subsidy calculations each plan year.
