So the IRS has released a preliminary form 1040 for 2018 to be filed in 2019.
It looks to be about an 8 1/2 inch wide by 5 1/2 inch tall. It is also extremely simple by itself.
But there are also additional schedules as well as forms and worksheets that are needed to actually file the 'postcard.'
For instance you still may have to file Schedule 1 (a catch all form for income and adjustments) Schedule A (if you itemize) Schedule C (if you have a small business) Schedule D (if you have capital gains or losses) Schedule E ( if you have rentals, investment in partnerships, S Corporations and LLC) Schedule SE (for self employment taxes) plus other forms and worksheets for other income and deductions.
So even though the postcard is only half the size of the previous 1040, there is still a lot of work to be done to file a return.
If you efile your return and/or use a preparer you will probably not notice any differences when you are filing.
Paper filing may be an adventure as you will have to send in just as much paperwork as before depending on your situation.
One more interesting thing about the postcard - it may be the size of a postcard but you will have to mail to the government in an envelope (you really don't want anyone to see the front and back of the postcard in the mail, do you?) Plus you may need to send the IRS a check.
Here is the preliminary form the IRS released:
