I was audited, they changed my filing status to married filing separate, they disallowed some of my income. I have not signed the 4549 because I now have proof of income that I did not have before, and I want to change filing status to married filing joint, because I was told if I was married for 6 months that I can file married filing joint.

I am thinking that it might solve the whole thing to ammend and change my filing status, as well as include the unincluded income and send it back with the unsigned 4549.

Is that the way to handle it or is there a better way.
