Understanding the 2023 Medicare Surcharge Tax

The Additional Medicare Tax for 2023 continues at a rate of 0.9% on earned income above certain thresholds. These thresholds remain at $200,000 for single filers and $250,000 for married couples filing jointly — notably, they are not adjusted for inflation.

This means more taxpayers cross these thresholds each year as wages increase, making it increasingly important to understand and plan for this tax alongside IRMAA surcharges.

How the Additional Medicare Tax Works

The 0.9% additional tax applies to wages, compensation, and self-employment income exceeding the threshold for your filing status. Different income types are considered separately for the tax calculation.

2023 Additional Medicare Tax Thresholds

  • Single/Head of Household: $200,000
  • Married Filing Jointly: $250,000
  • Married Filing Separately: $125,000
  • Tax Rate: 0.9% on income above threshold
  • Not indexed for inflation

Managing Medicare Taxes and Surcharges

Financial professionals should help clients understand the full picture of Medicare-related costs: the standard 1.45% Medicare tax, the 0.9% Additional Medicare Tax, the 3.8% Net Investment Income Tax, and IRMAA premium surcharges.

Strategic MAGI management can help minimize both IRMAA and Medicare surtax exposure. Understanding the interplay between these taxes is essential for comprehensive retirement planning.
