Federal & State tax not withheld by employer
Hello,
One of my friend's employer didn't withheld federal & state tax for the entire year 2006. Now his current year's tax is around $3,000. Last year's tax was around $275.
I want to know, whether he is supposed to pay any penalty or interest? If yes, then is there any option for paying only tax with the return & IRS will calculate penalty & send the bill? Or does he have to calculate penalty himself & pay when he pays tax.
How about State tax? He is in NJ.
Thanks in advance.
