Medicare tax is also known as the “hospital insurance tax” because it helps pay for a portion of the Medicare insurance program.

One of the primary functions of the Medicare tax is to pay for Medicare Part A, which provides insurance for seniors and persons with disabilities or medical conditions.

Medicare hospital insurance covers inpatient and outpatient hospitalization, hospice and nursing home care, and some in-home care for approved beneficiaries.

The main points

  • Medicare taxes help pay for older and handicapped people’s hospitals, hospices, and nursing home care.
  • By 2021, the Medicare tax rate will be 2.9%, and employees and employers will pay it.
  • However, 92.35% of business earnings are subject to Medicare taxation. Therefore self-employed individuals must pay for both components.
  • High incomes face an extra Medicare surtax on top of their regular income.

How is the Medicare tax calculated?

Every person who works in the United States must contribute to this system. Federal law requires employers to deduct Medicare and Social Security taxes from employee paychecks (FICA). Similar conditions arise under the SECA, making it mandatory for self-employed workers to pay Medicare and Social Security taxes as part of their self-employment tax.

US Treasury administers Medicare and Social Security taxes and deposits them in trust funds. Part A coverage payments help fund the costs of the Hospital Insurance Trust Fund.

The Supplemental Medical Insurance Trust Fund pays for Medicare Part D (dental insurance). The beneficiary payments, tax receipts, and investment gains(prescription drug coverage) fund it.

Moreover, the funding will assist both current and future Medicare members.

According to the 2019 Trustees Report, the Hospital Insurance Trust Fund, on the other hand, has been suffering financial and solvency challenges and is likely to run out of money by 2026. Medicare may cut services or look for alternate funding if this occurs.

The CORONAVIRUS Act, which takes effect in 2020, would increase Medicare coverage to include therapy for COVID-19 pandemic survivors. The Medicare plan covered COVID-19-related hospitalizations and durable medical devices.

Medicare tax rates

The Medicare tax rate was 2.9% in 2021, with the payment burden that employees and employers will share equally. W-2 employees contribute 1.45%, with their employer covering the rest. Self-employed individuals must pay the total 2.9% tax because they are both employees and employers. There is no upper-income limit.

Medicare charges the tax on your earnings as you relate to your age. “Taxable benefits” include salary, tips, vacation allowances, bonuses, commissions, and other taxable benefits, up to a maximum of $200,000.

There is a tax on Medicare premiums:

There is an additional Medicare tax and a net investment income tax to fund Medicare expansion. Both were introduced in 2014 under the Affordable Care Act (ACA). However, both are for high earners based on their tax bracket. A taxpayer can be subject to both Medicare surtaxes.

People who get additional benefits pay a supplemental Medicare levy.

Additionally, anyone with income above certain thresholds (including wages and compensation and self-employment income) pays an additional amount. Individuals earning more than $200,000 and married couples applying together making more than $250,000 pay Medicare tax more than others.

A 0.9% surcharge is added to the base Medicare tax, and the additional 0.9% is applied solely to income that exceeds the threshold level set by taxing authorities. The first $200,000 in yearly revenue is subject to 1.45%, and the remaining $25,000 is subject to an extra 0.9% Medicare tax.

Unlike the Medicare levy, however, there is no employer contribution. The employee bears a total of 0.9% of the overall responsibility amount.

Net investment income is taxable.

The net investment income tax is commonly known as the “unearned income Medicare contribution surtax.” It is a 3.8% additional tax on net investment income and existing taxes. Additionally, there is no employer-paid share of this premium.

Examples of net investment income include interest, dividends, nonqualified annuities, capital gains, and rental income. It excludes tax-exempt interest. It is charged on the lesser of an individual’s net investment income or the excess of modified adjusted gross income over specific levels.

This example describes a couple that together earned $225,000 in salary. Additionally, the couple received $50,000 in investment income during the same tax year, increasing their modified adjusted gross income to $275,000 for the year. The Married Jointly filing barrier is $250,000, and the Single Filer threshold is $250,000. The couple must send 3.8% of the lesser of the MAGI excess ($25,000) or the entire investment income ($50,000) to the government, and the couple would owe $950 in investment income tax (3.8% x $25,000).
