New York estimated tax (quarterly) calculator
Plan quarterly payments based on New York tax rules.
How this calculator works
Step 1 estimates your New York tax based on the taxable income you provide and the New York 4% to 10.9% brackets. The tool adjusts for New York-only income using your allocation %.
Step 2 uses your withholding and prior-year tax (if provided) to estimate a quarterly plan that aligns with New York's 90% current-year or 100% prior-year safe-harbor rules.
Step 3 divides the remaining tax into four equal payments and lists the standard due dates used by New York.
Frequently asked questions
When are New York estimated payments due?
New York uses the standard quarterly dates: April 15, June 15, September 15, and January 15 of the following year.
What if withholding changes later?
Recalculate with updated withholding to keep your quarterly plan accurate.
Is the safe harbor the same as federal?
New York generally follows a 90% current-year or 100% prior-year safe harbor. Special rules apply if at least two-thirds of your income is from farming or ranching.
Estimates use New York's published brackets (4% to 10.9%) and are not a substitute for official payment calculations.
