Got a “personal” bonus from my boss. Do I have to pay taxes and if so, how do I go about that?
Yes, it's taxable. If anyone suggests it's a gift, they are mistaken. There's a line on the 1040 for "other" and as long as you claim it, you're fine with the IRS. It's 2012 income as you already got it.  Edit - mhoran makes two good points I'm not really able to address. (a) does a late bonus such as this effect one's penalty? (b) since it skipped payroll, will there be an issue by not having FICA withheld?
