You still file taxes seperate. file 06 1st, get return then file 07.

I suggest contacting your employer(s) and request W2 copies for the years you are missing as well as the administrator for the 401K and request the required information, they should have record of the transaction. You don’t need to send in the actual W2 but you are required to keep your tax records for 7 years after filing and guessing isn’t the greatest idea. You can’t file a single return for both years but you can file both returns on the same day. You could file your 2007 return then later file your 2006 but it’s not the proper protocol. Good Luck!

You can get a print another w2 and 401K statement of income reported from your job. If they cannot find it or are out of business any local irs office can provide a copy. And although you cannot file 2006 and 2007 together, once irs receives both returns they will credit funds from overpayment to prior year less any penalties, interest and fees.

Dump that person doing your taxes and find someone else. if ez form you can probably do yourself and if under a certain amt irs rep will help you for free. if self employed hire a cpa
