Get your taxes done using TurboTax
TurboTax uses the IRS worksheet to do the calculation.
The Additional Medicare Tax is calculated on Form 8959.
The base number is
- W-2 Box 5 Medicare Wages
- plus unreported tips,
- plus Uncollected Social Security and Medicare Tax on Wages From 8919 line 6.
The allowable limits by filling status are:
- Single, HOH or Qualified Widow - $200,000
- Married filling Joint - $250,000
- Married filling Separate - $125,000
Subtract the allowable limit from the base number
This will yield the income subject to the additional tax.
The additional tax rate is 0.9%. So multiply by .009 .
This will yield the amount of additional tax.
