The bill puts income restrictions on insurance tax credits and drops a proposed cap on the tax break for employer-sponsored health coverage. The Congressional Budget Office has not released its estimate on how much the bill would cost. The legislation is expected to be marked up later this week.

The Republican-backed measure, called the American Healthcare Act, repeals most of the Affordable Care Act’s taxes, but at a later date than originally envisioned. It would keep the law’s “Cadillac tax” on high-cost health plans on the books, but would delay its implementation until 2025.

The tax credits proposed by Republicans would be age-based, not income-based as they are under Obamacare. But in the bill released Monday, they would be reduced for individuals earning more than $75,000 and for households earning more than $150,000. Individuals earning more than $215,000 couldn’t receive any of the tax credits.
