In 2002 I cashed in a 401k and received about 14,000. I knew about the taxes but didn't know for sure I would receive a penalty because everything I read said I "may" and I figured they would let me know... anyway, I owed the IRS 1,800 and they put me on a pmt plan of $25 to federal IRS every month but the part I don't understand is I have to pay $50 every 45 days to the state of Oklahoma when the 401k was from a job I had in Indiana and I had only just moved to Oklahoma when I cashed it out... can anyone explain this to me? Thanks
