I just started gathering my tax papers for 2005 and noticed that I have inadvertently exceeded the $14k 401k limit for the year. I changed employers in 2005 and so had already invested about $2500 at the first employer before closing that account, and rolling it over to an IRA. I then put the full $14k into my new 401k plan at my new employer. Dunno how I managed not to think of the obvious for close to a year, but it seems to be the case. What are my options?

At best, I suppose only $14k of the 401k contributions will be pre-tax, but is there any provision for after-tax dollars going into a 401k above the $14k limit? If not, how exactly do you "take back" an investment to satisfy the IRS?
