How to Get a Sales Tax Certificate in New York City
If you’re selling taxable goods or services in NYC, you need a sales tax certificate in NYC before you make your first sale. New York calls it a Certificate of Authority, and operating without one can mean fines, back taxes, and a shutdown order from the state. This guide walks you through exactly what it is, who needs one, and how to get it — step by step.
What Is a Sales Tax Certificate in NYC?
A sales tax certificate NYC businesses need is officially called a Certificate of Authority. It’s issued by the New York State Department of Taxation and Finance, and it’s what legally allows you to collect sales tax from customers and remit it to the state.
This isn’t a local NYC permit it’s a state-level registration that applies across New York, but it’s what every NYC business selling taxable goods or services needs to operate legally within the five boroughs. You need one whether you’re running a retail shop in Manhattan, a restaurant in Brooklyn, an online store shipping to NYC customers, or most service businesses that sell taxable items.
Without it, you can’t legally collect sales tax and if you’re supposed to be collecting it and aren’t, you’re still on the hook for what you should have collected, plus penalties and interest. The state doesn’t care whether you knew the rule or not.
Certificate of Authority vs. Resale Certificate — Don't Confuse Them
One of the most common mix-ups we see is between a Certificate of Authority and a resale certificate (Form ST-120). They’re not the same thing, and you may eventually need both.
Certificate of Authority lets you legally collect sales tax from your customers.
Resale certificate (ST-120) lets you buy inventory without paying sales tax, because you’ll be collecting tax from the end customer when you resell it.

You need a Certificate of Authority to register your business with the state. You use a resale certificate afterward, when you’re purchasing goods you intend to resell rather than use yourself. Confusing the two — or trying to use one in place of the other — is a fast way to end up with a compliance headache.
Who Needs a Sales Tax Certificate in NYC
Not every business needs one, but most that sell physical goods or certain taxable services in New York do. You generally need a Certificate of Authority if you:
- Sell tangible goods at retail, wholesale, or online to NY customers
- Operate a restaurant, bar, café, or other food service business
- Provide certain taxable services, such as some repair, maintenance, or installation work
- Sell at a temporary location, pop-up shop, or craft fair anywhere in NYC
- Run an e-commerce business that ships to New York customers, even if you’re based elsewhere
- Rent or lease tangible personal property
Some services are exempt — most professional services (legal, accounting, medical) generally don’t require sales tax collection, but the line isn’t always obvious. If you’re not sure whether your business falls into a taxable category, that’s worth confirming before you apply, not after you’ve already started collecting tax incorrectly.
NYC-Specific Considerations
New York City’s combined sales tax rate includes the state rate plus local NYC and MTA surcharges, which brings the total higher than many other parts of the state. Your Certificate of Authority covers your obligation to collect at the correct combined rate for wherever your sale is sourced — which matters more than you’d think if you sell across multiple boroughs, deliver goods, or run a mobile or pop-up business that moves around the city.
If you’re selling online to customers throughout New York State, not just NYC, you’ll also want to understand how destination-based sourcing affects which local rate applies to each sale.
How to Get a Sales Tax Certificate in NYC: Step by Step
1. Register Your Business First
You’ll need your business already registered LLC, corporation, partnership, or sole proprietorship with an EIN from the IRS before you apply for your Certificate of Authority. The state won’t process your application without a valid, matching business registration on file. If you haven’t set up your business structure yet, our Entity Formation Services team can help you do that correctly the first time, so you’re not backtracking later.
2. Gather Your Business Information
Before you start the application, have this ready so you’re not scrambling mid-process:
- Legal business name and any DBA (“doing business as”) name
- EIN (Employer Identification Number)
- Business address and mailing address
- Owner, officer, or responsible party information, including Social Security numbers for sole proprietors or partners
- Estimated start date for taxable sales
- A description of what you’re selling
3. Apply Through New York State
You apply for your Certificate of Authority through the NY State Department of Taxation and Finance’s Business Express portal. The application itself is free — the state doesn’t charge a fee for the certificate. Processing typically takes about 5 business days, but errors, missing information, or mismatches with your EIN can slow that down significantly, sometimes by weeks.
You can technically apply by mail as well, but the online portal is faster and gives you fewer opportunities to make a data-entry mistake that delays approval.
4. Wait for Your Certificate—and Display It
Once approved, the state mails you your Certificate of Authority. You’re legally required to display it at your place of business, and you can’t legally collect sales tax until you have it in hand. If you operate multiple locations, each one typically needs its own certificate or a properly registered branch under your main certificate — this is a detail that trips up multi-location businesses more than people expect.
5. Set Up Ongoing Sales Tax Filing
Getting the certificate is just the start. Once you’re registered, the state assigns you a filing frequency monthly, quarterly, or annually based on your expected sales volume. You’re required to file returns on that schedule even in periods where you made no taxable sales. Missing filings, even when you owe nothing, is one of the fastest ways to trigger a state audit or lose your certificate.
Costs, Timeline, and What to Expect
There’s no state fee to apply for a Certificate of Authority, which surprises some business owners who expect a licensing cost. The real cost is in getting the application right the first time a rejected or delayed application can push back your ability to legally open or sell, which has a real cost if you’re planning a launch date.
Typical timeline:
Business registration (EIN, entity formation): Can take anywhere from same-day to a couple of weeks, depending on entity type
Certificate of Authority application: Roughly 5 business days once submitted correctly
Total time to be fully operational: Often 1–3 weeks when everything is prepared in advance
Common Mistakes That Slow Down Your Application
Applying before your business is officially registered the state will reject the application outright.
Mismatched business information between your EIN, your entity registration, and your application.
Not knowing your filing frequency in advance, which leads to missed deadlines right out of the gate.
Collecting sales tax before your certificate is approved, which creates compliance problems you’ll have to unwind later.
Confusing the Certificate of Authority with a resale certificate and trying to use one to do the other’s job.
Forgetting to update the state when your business changes, new address, new owner, or change in business activity all require an update to your certificate.
What Happens If You Skip This Step
Selling taxable goods or services without a valid Certificate of Authority in NYC isn’t a minor paperwork issue. The state can assess penalties, hold you personally liable for uncollected tax, and in some cases suspend your ability to operate the business entirely. Unregistered vendors caught selling without a certificate can also face fines on top of the back taxes owed.
If you’ve been collecting sales tax without realizing you needed additional compliance steps, or you’re behind on filings, our Sales Tax Audit Services team can help you get caught up before it becomes a bigger issue. The sooner a gap like this gets addressed, the smaller it stays.
Do You Need to Renew Your Sales Tax Certificate?
Unlike some business licenses, a New York Certificate of Authority doesn’t expire on a set renewal cycle in the way a liquor license or professional license would — but it’s not something to treat as “set it and forget it” either. If your business changes ownership, moves locations, changes its legal structure, or stops selling taxable goods, you’re required to update or reapply for your certificate. Selling under an outdated or inaccurate certificate can create the same compliance problems as not having one at all.
