Free through NYBE
You apply online through New York Business Express, and there is no fee.
The short answer
File 20 days ahead
You cannot sell until the certificate reaches you. File at least 20 days ahead, and treat that as the earliest possible start date.
Display and file
Once granted, you must display it, file returns on the schedule you are given, and file even in periods with no sales.

Collect from the registered start date, then file every period.
Nothing may be sold until step 3 is done, even after 20 days pass. Launches slip because the certificate has to be in hand, not just applied for.

Start early
Free, quick — and gated by timing
Registering as a New York sales tax vendor is free and reasonably quick, and most of the trouble we see comes from starting too late rather than filing wrongly.
02Documents
Documents to gather for a Certificate of Authority application
- Confirm you need one. Selling taxable goods or services, having a physical presence in the state, or crossing the economic nexus threshold all trigger it. Who needs a Certificate of Authority covers each test, including which services the law names as taxable.
- Have your EIN. You cannot register without one, and obtaining an EIN is a separate federal step.
- Know your start date. The application asks when you will begin selling, and it needs to be at least 20 days out.
- Identify the responsible person. An owner or officer whose details go on the registration. This matters later, because sales tax carries personal liability for responsible persons.
03Where to apply
Applying through New York Business Express
The application goes through New York Business Express. There is no filing fee.
You will be asked for the entity's legal name and any trade name, the formation details, and the business address. New York also wants every location you will sell from, a description of what you sell, and the responsible person's information.
04Duties
Your duties once the certificate is granted
- Display it. The certificate has to be on show at the place of business it covers, and failing to display it carries a $50 penalty.
- Start collecting. From your registered start date, sales tax comes off every taxable sale.
- File on your assigned schedule. New York assigns quarterly, annual, or part quarterly filing on expected volume, and each return is due within 20 days of the period ending.
- File even when there is nothing to report. A zero return is still a return. Missing one because you had no sales is the single most common penalty we see on new registrations.
- Keep the records. Sales, exempt sales, and the resale certificates you accepted. On audit, an exempt sale without a valid certificate behind it becomes a taxable one.
05Changing ownership
Changing ownership, or surrendering the registration
The certificate does not expire. It stays valid until you surrender it or New York revokes it.
An address change is an update to your registration. A change of owner is not. A Certificate of Authority cannot be transferred or assigned.
Buying an existing business, taking over a family business, or converting a sole proprietorship into a corporation each require a new certificate, and the new business must hold it before it trades.
If you close or sell, surrender the certificate and file a final return. Leaving it open generates filing obligations for a business that no longer trades, and the penalties accrue against a responsible person who has stopped paying attention.
06FAQ
Certificate of Authority registration FAQs
How long does a Certificate of Authority application take?
Plan on more than 20 days. That figure is the notice New York asks for, not a processing time, and the department mails the certificate once it approves you. Nothing can be sold in the gap.
Is there a fee for a Certificate of Authority?
No. The sales tax registration costs nothing. The $225 charge belongs to the Department of State filing, which is a different document that happens to share the name.
What if I have no sales in a period?
File anyway. A zero return is still a return, and missing one on the grounds that there was nothing to report is the most common penalty we see on new registrations.
Do I need a new Certificate of Authority if I incorporate?
Yes. Changing legal form creates a new business for sales tax purposes, and it needs its own certificate in hand before it trades.

“As a solo founder running an LLC alongside W-2 income, my situation wasn't exactly simple. They took the time to actually explain what was happening with my return instead of just handing me paperwork.”
