Two of the biggest tax cuts in Republican proposals to repeal the Affordable Care Act would deliver roughly $144 billion over the coming decade to those with incomes of $1 million or more, according to a congressional analysis.

The assessment was made by the Joint Committee on Taxation, a nonpartisan panel that provides research on tax issues.

It is not unusual for tax cuts to benefit mostly the wealthiest, but still save some money for a majority of Americans. But the benefits of these reductions would be aimed squarely at the top.

The provisions would repeal two tax increases on high earners enacted in 2010 to help pay for the Affordable Care Act: an increase in capital gains taxes and other investment-related income, and a surcharge on Medicare taxes.
