Form 1040 is used by U.S. taxpayers to file an annual income tax return.
For Tax Year 2018, you will no longer use Form 1040A or Form 1040EZ, but instead will use the redesigned Form 1040. Many people will only need to file Form 1040 and no 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 Form 1040 Schedules. Below is a general guide to what Schedule(s) you will need to file. (See the instructions for Form 1040 for more information on the numbered schedules.) For Schedule A and the other lettered schedules, see Schedules for Form 1040.
