I was incarcerated from 2012 to 2014. Am I supposed to file taxes and if so how do I file or what do I file under since I paroled. I'm from Stockton CA. I await an answer.
Being incarcerated is irrelevant. You have to file taxes if you earn enough income to be required to file taxes. Most inmates won't earn enough, but it is quite possible you have income from other sources.
The minimum income beyond which you are required to file depends on your filing status, your age, and the year. It's just below $10,000 for 2012, and now appears to be just a little over, assuming you are single and under 65.
If in doubt, I'd recommend filing. If you don't owe anything, it won't cost you anything other than the hassle of filing. Again, there's nothing different about filing because you were incarcerated, it just may be more of a hassle to gather the information you need.
