DianeW777, your advice appears to differ from the IRS instructions for form 8959. The "Who Must File" paragraph begins: You must file Form 8959 if one or more of the following applies to you. •Your Medicare wages and tips on any single Form W-2 (box 5) are greater than $200,000 (followed by more reasons not of interest to me.)
I questioned my employer for withholding beginning at $200K when the threshold for owing the tax is $250K for MFJ, and they explained they are required to begin withholding at $200K for everyone because they cannot be certain you will still be married on 12/31 and file MFJ. Therefore, form 8959 is necessary to get credit for the excess Medicare tax withheld.
