Understanding the Medicare Surcharge Tax

The Additional Medicare Tax is a 0.9% surtax that applies to earned income above certain thresholds. For 2022, these thresholds were $200,000 for single filers and $250,000 for married couples filing jointly.

This tax is separate from the standard Medicare payroll tax (1.45%) and from IRMAA surcharges on Medicare premiums. Understanding both is essential for comprehensive retirement tax planning.

How the Additional Medicare Tax Works

The 0.9% additional tax applies to wages, railroad retirement compensation, and self-employment income above the threshold. Employers must begin withholding once wages exceed $200,000 — regardless of filing status.

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

Planning Strategies

For high-income professionals, understanding both the Additional Medicare Tax and Medicare IRMAA surcharges is essential. Together, these can significantly impact take-home pay and retirement income.
