New York income tax at a glance
This guide explains how New York fits into your overall filing picture. Your federal Form 1040 is only half the story—states add their own definitions, subtractions, credits, and withholding rules.
Most New York residents will prepare IT-201 alongside the federal return. NYC/Yonkers may add local tax (not modeled in all flows).
Withholding and W-2 boxes
If you work in New York (or your employer withholds for New York), compare boxes 15–17 on your Form W-2 to what you expect on the state return. Mismatches here are a common source of balance due surprises.
Credits, deductions, and quirks
State returns often start from federal adjusted gross income (AGI) and then apply state-specific subtractions, additions, credits, and alternative minimum taxes. Read your state instructions for the exact list—this page is a hub, not a substitute for official guidance.

Upload your PDFs, assign them to a return, and run compute. When BasilTax supports New York end-to-end, you can trace state lines to the same documents you used for federal.
