what can i do if my employer has deducted too much for medicare wages?

Answer 1

If your employer withheld more than 1.45% in Medicare tax, the employer must refund that to you.

You can only pursue this directly from the government if you have made a due-dilligence effort to recover it from the employer and the employer has failed to return the money to you. It doesn't matter if it's for the current tax year or a prior tax year, the debt is owed to you by the employer. If you attempt to get the money from the government, you'll have to provide evidence of the efforts you have made to recover the money.

Answer 2

I'm assuming you mean they deducted more than the 7.65% social security/medicare tax. If the overdeduction was made in the current year, the employer can and should make a correction and refund the extra tax to you. If it was in a previous year, you apply for a refund from the government.

Answer 3

Go to IRS.GOV and use the forms order section. There is a form you fill out and file to ask for a refund of excess medicare tax taken from wages.
