Hello I am now very worried about what additional payments/penalties I may owe at tax time for my 401K withdrawal. I lost my job last year and took out my 401K to support myself and my children. The taxable amount on the 1099-R I received says $25,520.29. It also says under federal income tax withheld $5104.06 and box 7 has a 1. I'm hoping you can give me an idea of what I may still owe IRS... I received unemployment benefits for about 9 months, of which I did have 10% tax withheld, and income of about $13,000 from first 3 months of the year... I think I'm really screwed, and since I still have not found another job, I do not have the $ to pay any owed penalty.. I was hoping for my normal refund to help us just get by a while longer... am I in BIG trouble?? Thanks for your help... I use to LIKE tax time, this year may really hurt me... J.H.
