Form 8959, Additional Medicare Tax, is required when your earned income, compensation, or self‑employment income exceeds the thresholds set by the IRS. Whether you are filing as an individual or on behalf of a small business, our Fill out this form button launches the Formize PDF Filler – a secure, browser‑based editor that lets you complete the form without downloading any software.
Form 8959 calculates the extra 0.9% Medicare tax that applies to high‑income earners. The tax is applied to wages, compensation, and self‑employment income above $200,000 (single) or $250,000 (married filing jointly). The form is attached to your annual Form 1040 filing.
Attach the completed Form 8959 to your Form 1040 when filing electronically or include it with your paper return. If you use a tax professional, provide them the saved PDF.
