Form 1040 is one of the most commonly filled out tax forms in the U.S. tax system. Because so many people need to fill it out on a yearly basis, it’s important to understand IRS Form 1040 instructions, including a full understanding of the basics of the 1040 form.

What is a 1040 Form?

With a Form 1040, you can report all types of income, expenses, and credits.

Previously, the IRS offered different types of Form 1040 – the 1040A and 1040 EZ.

New Form 1040 Instructions

Here are the new 1040 form instructions as of 2019 from the IRS:

You will use the redesigned Form 1040, which now has three new numbered schedules in addition to the existing schedules such as Schedule A. Many people will only need to ­use Form 1040 and none of the new numbered schedules. However, if your return is more complicated (for example, you claim certain deductions or credits or owe additional taxes), you will need to complete one or more of the new numbered schedules. Below is a general guide to which schedule(s) you will need to ­use based on your circumstances. See the 1040 instructions for the schedules for more information. If you e-file your return, you generally won’t notice much of a change and the software will generally determine which schedules you need.
