New York State sales and use tax is administered by the Department of Taxation and Finance under Articles 28 and 29 of the Tax Law. A business that makes taxable sales in New York registers for a Certificate of Authority, collects tax at the combined state and local rate for the delivery location, and files a return on a schedule the Department assigns.
Two features of the New York system surprise people who have filed elsewhere: the sales tax year runs March through February, not January through December, and the filing frequency is set by the Department rather than chosen by the business.
New York sales tax login
Sales Tax Web File lives inside Business Online Services, so the New York sales tax login is the Department's Tax Online Services Portal at ols.tax.ny.gov. Web File itself cannot be bookmarked — it is generated inside an authenticated session, so a saved link returns “You can only access this application through your Online Services account.” You also need a business NY.gov ID; a personal one will not reach it.

The numbers at a glance
New York's sales tax year runs from March 1 through the end of February. The quarters are March–May, June–August, September–November and December–February, each due 20 days after the quarter ends. A calendar-quarter assumption will make you late.
How the system fits together
1. Get a Certificate of Authority
Apply at least 20 days before you begin making taxable sales. Operating without one carries a penalty of up to $500 for the first day plus up to $200 a day after, to a $10,000 maximum.
2. Collect at the right rate
Rates are destination-based: the point of delivery determines the rate. Combined rates run from 7% to 8⅞% depending on jurisdiction.
3. File on the Department's schedule
Annual, quarterly or part-quarterly (monthly), assigned by the Department based on your receipts. Most new vendors start quarterly on Form ST-100.
4. Web File and claim the credit
Most vendors must file and pay electronically. Quarterly and annual filers who file on time and pay in full may keep 5% of the tax reported, capped at $200.
Things people most often get wrong
- Filing frequency is assigned, not chosen. Crossing $300,000 in taxable receipts, purchases subject to tax, rents and amusement charges in a quarter moves a vendor to monthly filing from the first month of the next quarter.
- Part-quarterly filers do not get the vendor collection credit. Neither do PrompTax enrollees, amended returns or past-due returns.
- A return is required even with no sales. The Department is explicit about it, and the minimum penalty for a late return with no tax due is $50.
- Being registered means being in business for sales tax purposes. Publication 750 puts it directly: once you hold a Certificate of Authority you are considered in business even if you never make a sale.
- Two different “Oneida” jurisdictions exist. Oneida County is 8¾%; the city of Oneida sits in Madison County at 8%.
