Employer did not deduct FICA and Medicare. How should I proceed?
On Dec 1st, I was notified by my employer that due to an error in reclassification of my immigration status in the payroll system when I transitioned from F-1 OPT to H-1B Visa, the appropriate FICA and Medicare taxes were not deducted from my paychecks in 2008. I was not aware of this error and, since (until recently) I had no idea about FICA and Medicare, I was sure that all appropriate taxes were deducted from me.
Now the employer wants to collect the debt owed from me before the end of the year. The employer wants to implement the following:
1. Company will pay to IRS the total debt owed. The amount paid by Company will be considered my additional earnings.
2. From my next six biweekly paychecks, 1/6 of the debt (per paycheck) will be deducted (that is approx. half of my net biweekly pay and, obviously, extends these deductions into the next year)
... and they are pressing me to sign a statement that I accept these terms ASAP.
At least from the way I am being treated, I feel like I need get an advice from a third-party tax professional before signing anything. However, I have no such opportunity at the moment as I am away on a business trip.
I've read IRS Publication 15 and understand that, in theory, underpaid FICA is employer's responsibility. But how is it in practice?
How should I proceed?
Thank you.
