I have never filed taxes so i can't use non filers portal.couse you need your last e sighn pin.or AGI,sence ive never filed i dont have either,i did wrk for about a month last year

You can use 0 as your prior year AGI when you file.   You create your own 5 digit pin when you file, so you don't need to have one from a previous year.  

I tried udong 0 and made up a pin.then i hit file and it just keeps coming bck.error chk. Name address ss#..i have chkd and double chkd.what next?
