"If my employer withholds Additional Medicare Tax from my wages in excess of $200,000, but I won't owe the tax because my spouse and I file a joint return and we won't meet the $250,000 threshold for joint filers, can I ask my employer to stop withholding Additional Medicare Tax?
No. Your employer must withhold Additional Medicare Tax on wages it pays to you in excess of $200,000 in a calendar year. Your employer cannot honor a request to cease withholding Additional Medicare Tax if it is required to withhold it. You will claim credit for any withheld Additional Medicare Tax against the total tax liability shown on your individual income tax return (Form 1040)."
