WASHINGTON — The new IRS Form 1040 will be released next week, and it will be significantly smaller than the current version, Treasury Secretary Steven Mnuchin said Wednesday.

“It will be a postcard, as we have promised,” he said at an event celebrating the six-month anniversary of the tax law that lowered rates and removed some tax breaks. “Hardworking taxpayers won’t have to spend nearly as much time filling out their taxes.”
