Under the American Health Care Act, tax credits would be based primarily on age, with a 64-year-old receiving twice as much help as a 21-year-old. But insurers could charge older adults up to five times more than younger adults, compared to three times more today. Tax credits wouldn’t go up in high-premium areas.

According to the Congressional Budget Office, a typical 64-year-old making $26,500 would have a net premium of $14,600 in 2026 under the Republican plan, compared to $1,700 under “Obamacare.” A 21-year-old making the same amount would pay slightly less than under “Obamacare” and a similar 40-year-old would pay slightly more.

Among people making $68,200, all three age groups would benefit under the GOP plan. The two younger groups would pay roughly three times less and the 64-year-old would pay slightly less.

Meanwhile, it’s not clear how many of the 242,000 people in Wisconsin who buy federally subsidized private insurance through the “Obamacare” marketplace would lose coverage under the Republican plan.
