A New York sales tax permit and a Certificate of Authority are the same document. The New York State Department of Taxation and Finance (the Tax Department) issues it, and you must hold one before you make any taxable sale in the state.
Any business selling taxable goods or services into New York needs one, whether you run a storefront or ship in from out of state. Registration is legally required before your first taxable sale. You apply as a sales tax vendor through the Tax Department’s official “Register as a sales tax vendor” page.

What Is a Certificate of Authority in New York?
A Certificate of Authority is New York’s name for a sales tax permit, issued by the New York State Department of Taxation and Finance. You need one before any taxable sale. It authorizes your business to collect sales tax and to issue and accept most New York State exemption documents, such as resale certificates. You must display it prominently at your place of business.
The certificate is the output of registering as a sales tax vendor. It applies to sales of taxable tangible personal property and taxable services, per the Tax Department registration page. A separate certificate is required for each business location.
Who Needs to Register for Sales Tax in New York?
You must register if you sell taxable goods or services in New York. This covers in-state sellers with any physical presence, out-of-state sellers who meet the economic nexus threshold, and businesses that sell through their own channels alongside marketplaces. New York requires registration before you begin business, whether you sell from a store, home, cart, or website.
The Tax Department states that every person selling taxable tangible personal property or services must register before beginning business, per its registration guidance. Physical presence and economic activity are separate triggers, covered in the two sections below.
What Is New York’s Economic Nexus Threshold?
New York’s economic nexus threshold is more than $500,000 in gross receipts from tangible personal property delivered into the state AND more than 100 such sales, measured over the immediately preceding four sales tax quarters, per the Tax Department’s nexus publication. Both conditions must be met. This “AND” test makes New York harder to trip into than states that use an “OR” test.
| Component | Requirement | Source |
|---|---|---|
| Gross receipts test | More than $500,000 from tangible personal property delivered into NY | Tax Department nexus publication |
| Transaction test | More than 100 such sales | Tax Department nexus publication |
| Test type | Both required (AND test) | Tax Department nexus publication |
| Lookback period | Immediately preceding 4 sales tax quarters: Mar 1–May 31, Jun 1–Aug 31, Sep 1–Nov 30, Dec 1–Feb 28/29 | Tax Department nexus publication |
| Effective date | June 21, 2018 (the Wayfair decision) | Tax Department nexus publication |
Once you cross both thresholds, the Tax Department requires you to register within 30 days and to begin collecting tax 20 days after that, per its nexus publication.
What Creates Physical Nexus in New York?
Any physical presence in New York creates nexus regardless of sales volume. That includes an office, store, or warehouse, inventory stored in the state (including stock held in a New York fulfillment center), and employees, agents, or salespeople operating there. Any one of these triggers a duty to register for a Certificate of Authority before you make taxable sales.
Inventory is the common surprise for online sellers. Goods you hold in a New York fulfillment center give you physical nexus even if you never cross the economic thresholds, per the Tax Department’s registration guidance.
How Does New York’s Marketplace Facilitator Law Affect Sellers?
Marketplace providers that meet the economic nexus threshold must collect and remit New York sales tax on behalf of their third-party sellers, per the New York State Department of Taxation and Finance. If you sell only through such marketplaces, you may not need your own Certificate of Authority for those sales. If you also sell through your own website or another channel and have nexus, you still must register.
The practical test is whether you have any direct sales channel or physical presence in New York. If you do, marketplace collection does not cover you, and you register as a sales tax vendor through the Tax Department.
Regular vs. Temporary Certificate of Authority: Which Do You Need?
Choose a regular certificate if you make taxable sales on an ongoing basis, and a temporary certificate if you expect taxable sales for no more than two consecutive sales tax quarters in a 12-month period. The temporary option fits seasonal vendors, craft-fair sellers, and pop-ups, per the New York State Department of Taxation and Finance.
Most businesses need the regular certificate. The temporary certificate exists so short-run sellers can collect tax legally without committing to permanent vendor status. Both are requested through the same sales tax vendor registration.
What Documents Do You Need to Register for Sales Tax in New York?
You need your business identity, tax IDs, responsible-person details, and activity description ready before you apply. Gathering these first prevents delays in your Certificate of Authority.
| Item | Notes |
|---|---|
| Legal business name and DBA | DBA means “doing business as,” your trade name |
| Business structure | Sole proprietorship, LLC, corporation, or partnership |
| Federal EIN | EIN is your Employer Identification Number; sole proprietors without one may use an SSN |
| SSN | Social Security Number, for sole proprietors and responsible persons |
| Physical and mailing addresses | Include business phone and email |
| NAICS code and activity description | NAICS is the North American Industry Classification System |
| Responsible-person details | Names, SSNs, and titles of owners, partners, or officers |
| Anticipated start date | The date taxable sales begin |
| Prior registration history | Whether you have registered in New York before |

How Much Does a New York Sales Tax Permit Cost?
A New York sales tax permit costs $0. The New York State Department of Taxation and Finance charges no application fee for the Certificate of Authority and no routine renewal fee, per its registration page. Free registration does not mean free compliance. Your duty to collect, file, and remit sales tax starts immediately once you begin taxable sales.
How Long Does It Take to Get a Certificate of Authority in New York?
Apply at least 20 days before you make taxable sales. The Tax Department frames 20 days as the recommended lead time and maximum expected wait, not a fixed processing time, per its how-to-register bulletin. Online applications through Business Express process faster than paper.
New York Business Express reports an average processing time of about five days for online applications, per its guidance. Applying early leaves room if the Tax Department needs more review.
What Happens If You Sell Without a Certificate of Authority in New York?
Selling taxable goods without a valid Certificate of Authority carries an escalating civil penalty, and you cannot legally issue or accept resale certificates. The Tax Department can also treat willful sales without a certificate as a misdemeanor under Tax Law §1817.
| Violation | Penalty | Source |
|---|---|---|
| First day of unauthorized sales | Up to $500 | Tax Department penalties bulletin |
| Each additional day | Up to $200 | Tax Department penalties bulletin |
| Maximum aggregate penalty | $10,000 | Tax Department penalties bulletin |
| Failure to display the certificate | Up to $50 | Tax Department penalties bulletin |
These amounts come from the Tax Department’s sales and use tax penalties bulletin. Owners and officers can also face personal liability for uncollected tax.
Does a New York Sales Tax Permit Need to Be Renewed?
No routine renewal is required. Your Certificate of Authority stays valid while you file and pay on time. New York Business Express notes the certificate is renewable at the Tax Department’s discretion, so the state can require re-registration in specific cases, per its guidance. Keep your account information current to stay in good standing.
What Are Your Obligations After You Register?
After you register, display the certificate prominently, collect sales tax on taxable sales, file returns on your assigned frequency, file zero returns for periods with no sales, and keep records. The Tax Department assigns monthly, quarterly, or annual filing based on your sales volume.
Quarterly returns are due no later than 20 days after the end of each sales tax quarter, per the Tax Department’s filing requirements bulletin. Failing to display the certificate carries a $50 penalty, so keep it visible at all times.
