<prompt> Human: Amidst a messy divorce and crippling depression that resulted from it Ive been incredibly irresponsible about my finances, living paycheck to paycheck and finally turned a corner and need to get my life back on track.How do I go about fixing my unfiled returns both federal and state CA?  <response>: I cant speak about state returns. But, I will relate how I fixed my 3 year didnt file situation with Federal. It was during a time when I wasnt making much and I figured that it was close so I just didnt file. I moved, got a better job and learned that I was due a significant sum as a refund. I found out that the IRS was serious about my filing every year even if it was close. So, I contacted my local IRS office, asked them what I should do and they told me to file. I said I didnt any of the information to do so. They got copies for all that stuff for the 3 years for me. I took it all home, filled out the 1040 EZ forms they had them, too and sent all 4 years off in the same envelope.Took just over an hour to finish up.I will say that I had tiny refunds due for each of those years. If it turns out that you will owe...Im sure theres a payment option to catch up.
