Employers must withhold Additional Medicare Tax— at a rate of 0.9%—
on wages or compensation paid to an employee in excess of $200,000 in
a calendar year.
Penalties for Noncompliance: Employers that do not deduct and
withhold Additional Medicare Tax as required are liable for the tax, unless
the tax they failed to withhold is paid by the employee. Even if not liable
for the tax, employers that do not meet their withholding, deposit,
reporting and payment responsibilities for Additional Medicare Tax may
be subject to the applicable penalties for willfully failing to deduct and
withhold.
Applicable large employers or ALEs (generally those with 50 or more
full-time employees, including full-time equivalents) must offer
affordable health insurance that provides a minimum level of coverage
("minimum value") to full-time employees and their dependents OR pay a
penalty tax if any full-time employee is certified to receive a premium tax
credit for purchasing coverage on the Health Insurance Exchange
(Marketplace).
Penalties for Noncompliance: There are two circumstances
under which ALEs may owe a penalty:
1. Employers Not Offering Coverage: For 2024, an ALE that does
not offer coverage or that offers coverage to fewer than 95% of its
full-time employees (and their dependents) during the calendar
year owes a penalty equal to the number of full-time employees
employed for the year (minus up to 30) multiplied by $2,970, as
long as at least one full-time employee receives a premium tax
credit. For an ALE that offers coverage for some months but not
others during the calendar year, the penalty is computed
separately for each month for which coverage was not offered.
The amount of the penalty for the month equals the number of
full- time employees employed for the month (minus up to 30)
multiplied by 1/12 of $2,970. For 2024, the rate is $2,970.
2. Employers Offering Coverage That Is Not Affordable or Does
Not Provide Minimum Value: For an ALE that offers coverage to
at least 95% of its full-time employees (and their dependents) but
has one or more full-time employees who receive a premium tax
credit, the penalty is computed separately for each month. The
amount of the penalty for the month equals the number of full-
time employees who receive a premium tax credit for that month
multiplied by 1/12 of $4,460. The penalty is the lesser of the
amount calculated or the amount that would be owed if the
employer did not offer coverage. For 2024, the rate is $4,460.
