Tax the rich? How Biden's budget proposal to save Medicare could work — and if it can.

President Joe Biden says he’s found a way to keep Medicare beneficiaries receiving full benefits for at least another 25 years: in part, make the rich pay more.

In his fiscal year 2024 budget proposal, Biden says he wants to raise Medicare taxes to 5% from 3.8% on annual income above $400,000 and eliminate a loophole business owners and high earners can exploit to avoid additional taxes, directing  revenue from that to Medicare. He also expects to save the federal government and seniors money by allowing Medicare to negotiate prices on more medications and sooner after they come to market.

If this sounds complicated, it’s because it is. Not only are there few details on how this would all work in practice, there are also a couple of different taxes involved. Here, we’ll try to break down what we do know.

What are the Medicare taxes now and who pays them?

There are three taxes to consider:

  1. Medicare Tax: The Medicare tax rate in 2022 is 2.9%, which is evenly split between an employer and employee, each paying 1.45%. The employee’s portion is taken out of each paycheck. “Economists generally agree (the employer’s portion) is passed on to employees in the form of lower wages,” according to the nonprofit, nonpartisan Institute on Taxation and Economic Policy (ITEP). “This means that most people pay a Medicare payroll tax equal to 2.9% of their earnings.”

  2. Additional Medicare Tax: Introduced with the Affordable Care Act (ACA), households earning more than $250,000 (or $200,000 for single filers) pay an additional 0.9% on their wage and salary income exceeding that amount. This brings the total Medicare payroll tax rate paid by these households to 3.8%.

  3. Net Investment Income Tax (NIIT): Also introduced with the ACA, this 3.8% tax is aimed at wealthy individuals who make more money through investments than wages. It’s applied to whatever portion of a household’s general income over $250,000 (or more than $200,000 for individual filers) is investment income. Though introduced with the ACA, NIIT revenue technically doesn’t currently fund Medicare.
