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.
