Form 1040 Tax Year 2017: A Comprehensive Filing Checklist
Overview of Tax Year 2017
The 2017 tax year marks full implementation of the Affordable Care Act shared responsibility requirements on line 61. This year does not involve Economic Impact Payment reconciliation, Tax Cuts and Jobs Act modifications, American Rescue Plan Act provisions, unemployment exclusions, or above-the-line charitable deductions that would apply in later years.
Form 1040 for 2017 permits standard income types, above-the-line deductions on lines 23 through 35, and credits on lines 48 through 54. For 2017, taxpayers could choose between Form 1040, Form 1040A, or Form 1040EZ, depending on their individual situations. Beginning with the 2018 tax year, Forms 1040A and 1040EZ will be discontinued.
