Hey, I landed in 2014 and was unemployed and then joined school in 2014 August till 2015 December and was searching for job (unemployed till 2016 April), I filed taxes for 2014,2015 and 2016. My question is for years 2014, and 2015? Was i required to file taxes as I was unemployed and student? Do i need to tick required or unrequired for the two years of unemployment and school?
