To get a reseller permit in New York, you apply online for a Certificate of Authority from the Department of Taxation and Finance through the New York Business Express portal. There is no fee, and you must register at least 20 days before your first taxable sale.1Department of Taxation and Finance. How to Register for New York State Sales Tax – Tax Bulletin ST-360 Once approved, the certificate lets you collect sales tax from customers and, just as important for most resellers, issue Form ST-120 to your suppliers so you can buy inventory tax-free.
New York does not use the phrase “reseller permit” in its own paperwork. The state document that gives you the authority to resell is the Certificate of Authority, and the document you hand a supplier to buy tax-free is the Resale Certificate (Form ST-120). You need the first one before you can legally use the second.
Who Needs to Register
You need a Certificate of Authority before your first transaction if you make retail sales of tangible personal property, charge for taxable services like repairs or cleaning, rent hotel rooms, or charge admission fees.2Department of Taxation and Finance. Selling Products or Services The requirement also applies if you only buy products for resale to other registered vendors and never sell directly to consumers.3New York State Senate. New York Tax Law 1134 – Registration That second category catches a lot of wholesalers and drop-shippers who assume registration only kicks in when you have retail customers.
Remote sellers with no physical presence in New York still need to register if, over the preceding four sales tax quarters, gross receipts from sales delivered into New York exceeded $500,000 and they made more than 100 such sales.4Department of Taxation and Finance. Sales Tax Nexus Both thresholds must be met. Crossing only one does not trigger registration.
One boundary worth naming: a Certificate of Authority is not the same as a sales tax exemption certificate. Exemption certificates are for nonprofits, government agencies, and certain educational institutions buying tax-free based on their exempt status. If you’re running a for-profit business making taxable sales, the Certificate of Authority is what you need.
What to Gather Before You Apply
The application is Form DTF-17. Pulling your information together before you start saves time, because the online system asks for everything in one sitting.5Department of Taxation and Finance. Instructions for Form DTF-17 – Application to Register for a Sales Tax Certificate of Authority
- Federal Employer Identification Number (EIN). Required for partnerships, corporations, LLCs, and any business that will hire employees. A sole proprietor without employees can use a Social Security number instead.
- Legal name and any trade name. Your exact registered legal name, plus any DBA you operate under publicly.
- NAICS code. A six-digit code identifying your primary business activity. The Department lists these in Publication 910.
- Responsible person information. Names, home addresses, and Social Security numbers for every person with a duty to act on behalf of the business. For a corporation that means the CEO, CFO, president, treasurer, and secretary. For an LLC, all members and any appointed managers. For a partnership, all general partners.
- Business start date. The date you expect to make your first taxable sale. The Department uses this to assign your first filing period, and it will expect a return for that period even if you make no sales.
- Business location and mailing address. Where you keep records and where you want tax correspondence sent.
Have Form DTF-17.1, the Business Contact and Responsible Person Questionnaire, filled out for each responsible person before you start.6Department of Taxation and Finance. Register as a Sales Tax Vendor If your business has multiple locations, you will also need Form DTF-17-ATT to list each one.7Department of Taxation and Finance.

Applying Online Through New York Business Express
Registration runs through the New York Business Express portal at businessexpress.ny.gov. You will need a NY.gov Business account to access it. A personal NY.gov account, if you already have one, will not work; the Business account is separate.6Department of Taxation and Finance. Register as a Sales Tax Vendor
Once you’re in, work through the prompts and enter the information listed above. At the end you get a confirmation page. Print it and save it with your records. The Department sends status updates by email from noreply.businessexpress@custhelp.com, so watch that inbox. You’ll get notifications when your application is submitted, when it needs attention, and when it has been approved.
The Department does not publish a guaranteed processing time. Plan around the 20-day window the law already requires. Incomplete applications and mismatched information (a legal name that doesn’t line up with your other state filings, for example) are the fastest way to delay approval.
What Happens After Approval
The Department mails a physical Certificate of Authority to your registered business address. New York Tax Law requires you to display it prominently at the place of business listed on the certificate.3New York State Senate. New York Tax Law 1134 – Registration If you sell from a cart, truck, or market stand rather than a fixed location, attach the certificate to each merchandising device you use.
The certificate is tied to the address on its face. If you operate from multiple locations, you get a separate certificate for each. A certificate issued for your warehouse does not cover a pop-up shop in another county.
Using Form ST-120 to Buy Inventory Tax-Free
With your Certificate of Authority active, you can issue Form ST-120, the Resale Certificate, to suppliers when purchasing inventory you intend to resell.2Department of Taxation and Finance. Selling Products or Services Handing over a completed ST-120 means the supplier doesn’t charge you sales tax. You collect the tax later, when you sell the product to the end consumer.
Timing matters on both sides of this. Suppliers have 90 days from delivery to collect a valid resale certificate from you. Without one in that window, the sale is presumed taxable and the supplier is on the hook for the uncollected tax.8New York State Senate. New York Tax Law 1132 – Collection of Tax From Customer When you’re the seller, the rule flips: get a resale certificate from your buyer within 90 days or treat the sale as taxable.
Penalties for Skipping Registration or Misusing the Certificate
Making taxable sales without a Certificate of Authority carries steep fines. New York can impose up to $500 for the first day of unauthorized sales or purchases, plus up to $200 for each additional day, capped at $10,000.3New York State Senate. New York Tax Law 1134 – Registration Failing to file the required certificate of registration at all can bring an additional penalty of up to $200. These are civil penalties, separate from any tax you actually owe.
Misusing the resale certificate is the more common trap for new business owners. Handing an ST-120 to a supplier for something you’ll use personally, or use inside the business rather than resell, exposes you to:
- A penalty equal to 100% of the tax that should have been paid on the purchase.
- A $50 penalty for each fraudulent resale certificate issued.
- Criminal prosecution. Willfully issuing a resale certificate with intent to evade tax can be charged as a felony under New York law.
- Revocation of your Certificate of Authority, which shuts down your ability to make taxable sales.
The ST-120 itself spells out these consequences in its certification language, and auditors know the patterns to look for.9New York State Senate. New York Tax Law 1145 – Penalties and Interest If you buy something tax-free for resale and then use it in the business instead, you owe the tax. Report it as a taxable purchase on your next sales tax return rather than waiting for an audit to surface it.
Keep every resale certificate you accept, every purchase invoice, every sales record, and every filed return for at least three years, which is the general statute of limitations on New York sales tax audits.10Department of Taxation and Finance. Publication 130-D – The New York State Tax Audit: Your Rights and Responsibilities For any period where you never filed a return, no statute of limitations applies at all.
