A New York tax-exempt certificate is the document a buyer hands to a seller to make a purchase without paying sales tax, and the specific form you need depends on why the purchase qualifies. Nonprofits use Form ST-119.1. Businesses buying inventory to resell use Form ST-120. Manufacturers and qualifying research operations use Form ST-121. Government employees on official travel use Form ST-129. Each form has its own qualification path, its own rules for how and when to present it, and its own audit exposure if used incorrectly.
Which Certificate You Need
The reason for the exemption drives the form. Getting this wrong is one of the most common ways a claimed exemption falls apart on audit.
- Form ST-119.1, Exempt Organization Exempt Purchase Certificate. This is what a qualifying nonprofit presents at the point of sale. The state mails it to the organization once the exemption application is approved.1New York State Department of Taxation and Finance. Sales Tax Exempt Organizations
- Form ST-120, Resale Certificate. Used by registered vendors buying goods they intend to resell. No state approval is required to issue it, but the buyer must already hold a valid Certificate of Authority.2New York State Department of Taxation and Finance. New York State and Local Sales and Use Tax Resale Certificate
- Form ST-121, Exempt Use Certificate. Covers machinery, equipment, and supplies used directly and predominantly in manufacturing, production, or qualifying research and development. “Predominantly” means more than 50% of the time. It also covers fuel and utilities consumed exclusively in production.3New York State Department of Taxation and Finance. Exempt Use Certificate
- Form ST-129, Exemption Certificate for Hotel Occupancy. For government employees claiming exemption from state and local sales tax on hotel stays taken on official business.4New York State Department of Taxation and Finance. Purchases and Sales by Governmental Entities
One point worth clearing up before anyone hands a piece of paper to a cashier: the ST-119 is the status certificate the state issues to an approved nonprofit. It is not the form you give the vendor. The form you actually present is the ST-119.1. Handing over the ST-119 at checkout tends to produce confused looks and refused exemptions.
Qualifying for Nonprofit Exempt Status
New York Tax Law Section 1116 controls who qualifies as an exempt organization. The main categories are nonprofits organized and operated exclusively for religious, charitable, scientific, literary, or educational purposes, along with organizations that prevent cruelty to children or animals. No part of the organization’s earnings can benefit any private individual, and it cannot devote a substantial part of its activities to lobbying or take part in political campaigns for or against any candidate.5New York State Senate. New York Code TAX 1116 – Exempt Organizations
Federal and New York State government entities, political subdivisions, and public corporations are exempt as well. For federal employees traveling on business, the exemption tracks the payment method, not the person. A GSA SmartPay purchase card that is centrally billed qualifies for exemption in all states; a personal credit card used by the same employee does not.6GSA SmartPay. Frequently Asked Questions
For a nonprofit, exempt status in New York is a two-step process. First, the IRS must issue a determination letter recognizing the organization under Section 501(c)(3) or another qualifying section. Organizations that received their letter on or after January 1, 2014, can retrieve a copy through the IRS Tax Exempt Organization Search tool; older letters require Form 4506-B. Organizations under a group exemption ruling should go through their central organization instead of the IRS.7Internal Revenue Service. EO Operational Requirements: Obtaining Copies of Exemption Determination Letter From IRS
With the IRS letter in hand, the organization files Form ST-119.2, Application for an Exempt Organization Certificate, with the New York State Department of Taxation and Finance. The packet must include the organization’s articles of incorporation, charter, or trust agreement with any amendments; current bylaws; a full description of current and proposed activities; and financial statements showing receipts, expenditures, assets, and liabilities for the most recent fiscal year. The completed application goes to the Sales Tax Exempt Organizations Unit in Albany.8New York State Department of Taxation and Finance. A Guide to Sales Tax in New York State for Exempt Organizations
Once approved, the state issues Form ST-119, which carries a six-digit New York sales tax exemption number. That number is specific to New York and is entirely separate from the organization’s nine-digit federal EIN. The state explicitly warns that the federal EIN is not a sales tax exemption number.1New York State Department of Taxation and Finance. Sales Tax Exempt Organizations The organization’s name and address on the application must match its IRS records exactly, and later changes to legal name or location need to be reported to keep exempt status active.
Using a Resale Certificate
Form ST-120 works on a different track. There is no state approval process. The buyer fills in the form, provides the sales tax identification number from their Certificate of Authority, and hands it directly to the seller.2New York State Department of Taxation and Finance. New York State and Local Sales and Use Tax Resale Certificate
Timing matters. The certificate must reach the seller no later than 90 days after delivery of the goods. If it arrives after that, both the buyer and the seller carry the burden of proving the sale was actually exempt, and the state can demand additional documentation.2New York State Department of Taxation and Finance. New York State and Local Sales and Use Tax Resale Certificate
Buyers who purchase regularly from the same supplier can check the blanket certificate box instead of the single-purchase box. A blanket certificate covers all similar future purchases from that seller and stays in effect indefinitely, provided the buyer keeps making exempt purchases. Any change to the buyer’s address, identification number, or other details requires an updated certificate, and the seller can also request an update at any time.9New York State Department of Taxation and Finance.

Seller Obligations and Recordkeeping
Sellers carry real exposure in these transactions. A properly completed certificate accepted in good faith protects the seller from liability for the uncollected tax. That protection disappears if the seller knew the purchase was not for an exempt purpose or knew the certificate was false or fraudulent.9New York State Department of Taxation and Finance. Exemption Certificates for Sales Tax
Every certificate must stay on file for at least three years from the due date of the sales tax return on which the last covered sale was reported.10Legal Information Institute. N.Y. Comp. Codes R. and Regs. Tit. 20 533.2 – Records to Be Kept The seller also needs a way to link each exempt sale to the specific certificate that supports it. Auditors will ask for both the certificate and the corresponding invoice; if the certificate is missing or incomplete, the seller can end up owing the tax that should have been collected.
The state applies an “ordinary care” standard. That means checking that every required field is filled in, that the buyer’s identification number is present, and that the stated reason for exemption makes sense given what is being bought. A restaurant supply company accepting a resale certificate from a law firm buying office furniture is the classic example of a seller who should have asked questions. Ignoring obvious problems forfeits the good-faith protection.
Penalties for Misusing a Certificate
The consequences of misuse land from more than one direction. On the civil side, when a failure to pay sales tax is due to fraud, the penalty doubles to two times the tax owed, plus interest at 14.5% per year or the state’s underpayment rate, whichever is higher.11New York State Senate. New York Code TAX 1145 – Penalties and Interest Even without fraud, late-filing penalties start at 10% of the tax due for the first month and add 1% each additional month, up to 30%, with a $50 minimum for registered vendors who fail to file.
Criminal exposure exists as well. Anyone required to hold a Certificate of Authority who willfully sells taxable goods, or buys goods for resale, without a valid certificate commits a misdemeanor. A second offense within five years of a prior determination to suspend or revoke the certificate carries a mandatory minimum fine of $500 on top of any other penalties.12New York State Senate. New York Consolidated Laws, Tax Law – TAX 1817 The state can also revoke the Certificate of Authority outright, which ends the business’s ability to collect sales tax or claim any exemption going forward.2New York State Department of Taxation and Finance. New York State and Local Sales and Use Tax Resale Certificate
Using a certificate to avoid tax on personal purchases, or on items unrelated to the exempt purpose, is not a gray area. Auditors look for patterns, and the penalties are structured to dwarf whatever tax was avoided.
How Long a Certificate Stays Valid
Validity depends on the type. Government exemptions are permanent and require no renewal. A nonprofit’s ST-119 has no built-in expiration date and stays in force as long as the organization continues to operate within the requirements of Tax Law Section 1116, but the organization must keep its state records current. Unreported changes to legal name, address, or organizational purpose can interrupt exempt status.
A resale certificate is only as valid as the buyer’s Certificate of Authority behind it. If the state suspends or revokes that Certificate of Authority, every ST-120 the buyer has issued becomes invalid. A seller who continues accepting those certificates could face liability for the uncollected tax if there was reason to know the buyer’s registration had lapsed. Businesses relying on blanket resale certificates from regular customers should periodically verify each buyer’s registration status with the Department of Taxation and Finance.9New York State Department of Taxation and Finance.

Exemptions That Skip the Certificate Entirely
Some New York sales tax exemptions do not involve any paperwork at the register. Clothing and footwear sold for less than $110 per item or pair are exempt from the state’s 4% sales tax automatically, no matter how many items are in the transaction. A shopper buying five $100 shirts pays no state sales tax on any of them. Some counties and cities impose their own local sales tax on clothing regardless of price, so the local piece varies by location.13New York State Department of Taxation and Finance. Clothing and Footwear Exemption
Most grocery food, prescription drugs, and certain medical equipment are also exempt without a certificate. These are built into the tax code under Section 1115 and apply to every buyer, not just qualifying organizations or registered vendors.14New York State Senate. New York Code TAX 1115 – Exemptions From Sales and Use Taxes If your exemption fits one of these categories, there is no form to file and nothing to hand the cashier.
