New York applies a statewide base sales tax of 4% as of 2025, but counties and cities add their own local rates on top, so the real rate you pay depends on location. This calculator adds or removes sales tax at whatever rate you set, instantly and entirely in your browser.
How it works
The calculator uses your rate (default 4%) in one of two modes:
- Add Sales Tax — tax = price × (rate ÷ 100), and total = price + tax.
- Remove Sales Tax — the entered amount is the tax-inclusive total, so pre-tax = total ÷ (1 + rate ÷ 100), and the tax is the difference.
Because New York is a destination-based state with local add-ons, set the rate field to your combined rate — for example 8.875% in New York City — for a real-world total.
Example
On a $100 pre-tax purchase at the 4% state base rate:
| Field | Value |
|---|---|
| Pre-tax | $100.00 |
| Sales tax (4%) | $4.00 |
| Total | $104.00 |
At the NYC combined rate of 8.875%, the same $100 item costs $108.88. To reverse a tax-inclusive total in Remove mode, divide by 1 plus the rate (for example $108.88 ÷ 1.08875 = $100.00).
Important: New York’s state rate is 4%. Local taxes (county + city) typically add 3-5%, so NYC residents pay 8.875% combined. Groceries and prescription drugs are exempt.
All calculations run entirely in your browser — no amounts or personal data are transmitted.
