The Affordable Care Act (ACA) helps millions of Americans reduce the cost of health insurance through income-based subsidies, also known as premium tax credits. But how exactly are these subsidies calculated — and how can you estimate yours for 2026 coverage?
In this guide, we'll break down the ACA subsidy formula, income requirements, and how your household size and location affect your monthly savings.
✅ What Are ACA Subsidies?
ACA subsidies are tax credits that lower your monthly health insurance premiums when you buy a plan through the HealthCare.gov marketplace or your state exchange. They are officially called premium tax credits.
The amount you qualify for depends on your income compared to the Federal Poverty Level (FPL), your household size, and the benchmark plan in your area.
🧮 The ACA Subsidy Formula (Simplified)
Here's how the subsidy is calculated:
- Estimate your Modified Adjusted Gross Income (MAGI) for 2026
- Find your income as a % of the Federal Poverty Level
- Determine your expected premium contribution (a % of income)
- Subtract that from the cost of the benchmark Silver plan in your area
💡 Example: A household of 3 making $45,000 per year in 2026 might qualify for a $450/month subsidy, depending on their ZIP code and ages.
📊 2026 Federal Poverty Level (FPL) Estimates
ACA subsidies are generally available to households earning between 100% and 400% of the FPL. However, under recent laws, many people above that level still qualify.
Here are estimated income limits for 2026 (lower 48 states):
| Household Size | 100% FPL | 400% FPL |
|---|---|---|
| 1 | $14,900 | $59,600 |
| 2 | $20,100 | $80,400 |
| 3 | $25,300 | $101,200 |
| 4 | $30,500 | $122,000 |
These numbers can vary by year and state, so it's best to use a subsidy calculator to get an accurate 2026 estimate.

💬 Common Questions
Do I need to file taxes to get an ACA subsidy?
Yes. You must file a federal tax return and reconcile your premium tax credit using Form 8962.
Are ACA subsidies available to self-employed people?
Yes. Self-employed individuals can estimate their annual MAGI and qualify based on that projection.
Can I qualify if I already have employer coverage?
Usually not, unless your employer plan is deemed unaffordable. This is known as the "family glitch."
