Once i change filing status from 2015 will i have to change whole return

[viray77]

It's look like you want to amend your 2015 tax return? In my case, I am changing my filing status from filing separately to filing jointly. I have some changes for example; the total gross income and exemptions amounts will be increase.  You may have to include or exclude some credits depending upon the status. For example, my educational credit wasn’t included in filing separately but you can in filing jointly.  In short, you don’t change the whole return. Form 1040X is the form that you need to use to amend your tax return. It will show the increase and decrease of amount to be changed in that form. I hope this will help you. Good luck.
