The Medicare Surtax, also known as the Additional Medicare Tax, is an extra tax levied on high-income earners in the United States. It was introduced as part of the Affordable Care Act (ACA) to support the Medicare program by increasing revenue from taxpayers with higher earnings.
How It Works: Applicability and Thresholds
The Medicare Surtax is applied only to income that exceeds specific thresholds based on the taxpayer’s filing status. As of 2023, the thresholds are as follows:
- Single and Head of Household: $200,000
- Married Filing Jointly: $250,000
- Married Filing Separately: $125,000
The surtax rate is 0.9% and is added to the existing Medicare Tax rate for earnings beyond these thresholds.
Calculation Example
Let’s consider an example for a single filer:
- Gross Income: $250,000
- Threshold for Single Filer: $200,000
- Excess Income Subject to Surtax: $50,000
- Medicare Surtax Rate: 0.9%
The Additional Medicare Tax would be calculated as:
Thus, the taxpayer would owe an additional $450 in Medicare Surtax.
Special Considerations
Employer Responsibilities
Employers are required to withhold the Additional Medicare Tax from an employee’s wages if they exceed $200,000 in a calendar year, regardless of the employee’s filing status or additional income from other sources.
Self-Employed Individuals
Self-employed individuals must include the Medicare Surtax in their estimated tax payments and are subject to the same income thresholds.
Married Couples
For married couples filing jointly, both spouses’ incomes are combined to determine whether they exceed the $250,000 threshold. This combined consideration can significantly impact the tax liability.
Historical Context
The Medicare Surtax was implemented in 2013 as part of the ACA to help finance Medicare, a critical program providing health coverage to individuals aged 65 and older and to certain younger people with disabilities.
