For tax year 2018, the Internal Revenue Service introduced the "postcard" 1040, along with six new schedules (to make up for chopping the Form 1040 in half). Forms 1040-A and 1040-EZ were also eliminated.
For tax year 2019, the Internal Revenue Service is introducing the Form 1040-SR, U.S. Tax Return for Seniors.
Interestingly, the old Form 1040 was largely able to accommodate everything the 1040-A, 1040-EZ, the new "postcard" 1040, and the 1040-SR could accommodate without the six additional schedules.
So while these curious new forms are somewhat interesting, they have done little, if anything, to streamline tax filing. This seems to be another case of the government fixing something that is not broken, as the Form 1040 was a finely-honed and efficient form that did an exemplary job of reporting individual income to the Internal Revenue Service.
