New York Resale Certificate: How Resellers Get One (2026 Guide)

Every wholesale application eventually reaches the same line: attach your resale certificate. For resellers registered in New York, that document is the New York State and Local Sales and Use Tax Resale Certificate — proof that you are buying inventory for resale, not consumption, so the supplier does not have to charge you sales tax.

This guide covers the New York specifics: which agency issues what, the exact form, what it costs, how long it takes, and how your suppliers will verify it. It is part of our step-by-step wholesale sourcing roadmap.

The documents in New York

Certificate: New York State and Local Sales and Use Tax Resale Certificate (ST-120). Prerequisite registration: Certificate of Authority (apply via Form DTF-17 / NY Business Express). Issuing agency: New York State Department of Taxation and Finance.

How to get it, in order

1. Register for the Certificate of Authority (apply via Form DTF-17 / NY Business Express) with the New York State Department of Taxation and Finance. Cost: $0. Typical timing: About 5 business days online; apply at least 20 days before doing business.
2. Self-completed blanket or single-purchase certificate given to suppliers; NY-registered purchasers must list their Certificate of Authority number, and using ST-120 without a valid Certificate of Authority when required carries steep penalties.
3. Send the completed certificate to each distributor at account opening, and keep a copy — most suppliers keep blanket certificates on file so you do not repeat this for every order.

Out-of-state suppliers and buyers

NY does not accept the MTC uniform form, but ST-120 Part 2 lets out-of-state purchasers not required to register in NY use their home-state registration number.

How suppliers verify your certificate

New York provides an online lookup where a supplier can confirm your registration is valid: official verification tool. Expect serious distributors to use it — verifying buyer credentials is a standard part of wholesale onboarding, and supplier profiles in our catalogue note when a resale certificate is required.

FAQ

Does it expire?

Certificate of Authority generally does not expire (DTF may require reregistration); blanket ST-120 remains valid until revoked or information changes.

Can I buy wholesale without one?

Usually yes — but the supplier must then charge you sales tax, which comes straight out of your margin, and some distributors simply refuse accounts without resale documentation. Getting the certificate first is almost always worth it.

Anything specific to New York?

NY sales tax audits are aggressive; keep ST-120s complete and dated within 90 days of first sale. Amazon/marketplace sellers with NY nexus still need their own Certificate of Authority to issue ST-120.
