A Utah tax ID number lookup usually means one of two things, and the database you need depends on which. The Entity Number, which confirms a business is legally registered in Utah, is searchable free through the Division of Corporations. The Utah State Tax Commission (USTC) account number, which tracks sales tax, withholding, and other state tax filings, is treated as confidential and is not offered through a public search-by-name tool.1Utah State Tax Commission. Create, Manage, or Update a Business Tax Account Both are separate from the federal Employer Identification Number issued by the IRS.2U.S. Small Business Administration.

Knowing which number you actually need saves a lot of time. Vendors confirming that a business can legally collect sales tax want the USTC account number. Someone checking whether a company is real, active, and in good standing before signing a contract wants the Entity Number. Many situations call for both.
Looking Up the Entity Number
The Utah Division of Corporations runs a free public Business Entity Search at secure.utah.gov/bes.3Utah Department of Commerce. CORP Searches No login, no account. The search accepts either the business’s legal name or a known Entity Number. You can also search by registered agent name, and a separate registered principal search is available for a $3 fee, which helps when you know the owner but not the exact company name.4Utah Department of Commerce. CORP About
Use the exact legal name on file. Searching “Bob’s Auto” when the business registered as “Robert’s Automotive LLC” returns nothing useful. If you’re unsure of the exact form, drop trailing words like “LLC” or “Inc.” and let the results narrow themselves.
What the Results Show
Clicking into a result opens a detail page with the Entity Number displayed prominently, along with:
- Status — Active, Expired, or Delinquent
- Entity type — LLC, corporation, partnership, nonprofit, or other
- Registration date
- Registered agent name and Utah physical address
- Principal address on file
An Expired or Delinquent status means the business has fallen behind on required annual filings. That does not mean the business no longer exists, but it does mean the entity may be blocked from entering contracts, applying for loans, or defending lawsuits until it reinstates.5Utah Department of Commerce. CORP Renewal Process
From the same search tool you can also order a Certificate of Existence, the official state document confirming the entity is registered and in good standing. That certificate is commonly required for business loans, bank accounts, and registering to do business in another state.3Utah Department of Commerce. CORP Searches
Finding a USTC Account Number
The Tax Commission does not offer a public search-by-name lookup for USTC account numbers. Tax account information is confidential, and the state’s online tools are built for account holders to manage their own filings, not for third parties to search other businesses. How you find the number depends on whose account it is.
If It’s Your Own Business
Your USTC account number appears on any prior state tax return you’ve filed, on your original sales tax license, and on correspondence from the Tax Commission. Checking old records is usually the fastest route.
If you have online access, log in to the Taxpayer Access Point at tap.tax.utah.gov. TAP is the state’s primary portal for applying for tax accounts, filing returns, making payments, and viewing account information.6Utah State Tax Commission. Online Services When you first registered your business for sales tax or withholding, the Tax Commission mailed you the account number and a PIN. If either has been lost, you can request them by emailing TAPSupport@utah.gov (include your username and, if you have it, your account number) or by calling 801-297-3996.7Utah State Tax Commission. TAP FAQ – Registration Expect to verify your identity as the account owner or registered agent before the Commission releases anything.
If You’re Verifying Another Business
The most reliable approach is to ask the business for a copy of its sales tax license. The license displays the USTC account number and confirms the business is authorized to collect sales tax in Utah. This is standard practice in business-to-business transactions, and legitimate vendors expect the request.
If direct verification isn’t practical, contact the Tax Commission at 801-297-2200 or toll-free at 800-662-4335. General tax questions can also be sent to taxmaster@utah.gov.8Utah State Tax Commission. Contacting the Tax Commission The Commission can confirm whether a business holds an active sales tax license, though it may decline to release the full account number to a third party.
What About the Federal EIN?
The federal Employer Identification Number is issued by the IRS and is not part of any Utah lookup.2U.S. Small Business Administration. Get Federal and State Tax ID Numbers Neither the Division of Corporations database nor the USTC’s records display it. If someone has asked you for a Utah tax ID and you’re holding an EIN, that’s a different number, and you may need to register with the state separately.
If the Business Isn’t Registered Yet
If a search of the Division of Corporations returns nothing, the entity may never have registered. On the tax side, businesses apply for a USTC account by completing Form TC-69 through TAP.9Utah State Tax Commission. Sales and Use Tax The single application covers sales tax, withholding, and other state tax types. During the application, new businesses estimate their expected sales tax liability, and the Tax Commission assigns a filing frequency of monthly, quarterly, or annually based on that estimate. Owners, partners, or officers with prior late filings or unpaid balances need to clear those first, and the Commission may require a surety bond before issuing a license.10Utah State Tax Commission. Sales and Use Tax FAQ
Out-of-state sellers often need a USTC account too. Utah requires remote sellers to register, collect, and remit sales tax if they receive more than $100,000 in gross revenue from sales of tangible goods, electronically transferred products, or services consumed in Utah during the current or previous calendar year.11Utah State Tax Commission. Out-of-State (Remote) Sellers The rule has been in effect since January 1, 2019, following South Dakota v. Wayfair. Remote sellers register through the same TAP portal.6Utah State Tax Commission.

When the Entity Shows as Expired or Delinquent
All registered Utah entities must file an annual report to keep an active status.5Utah Department of Commerce. CORP Renewal Process Missing that filing doesn’t dissolve the business immediately, but the status change carries real consequences for anything that requires proof of good standing.
Reinstatement is available through the Division of Corporations. The fee is $54 for a domestic LLC or corporation, and $30 for a nonprofit corporation.12Utah Department of Commerce. Updated Fee Schedule The process also asks you to update information on file, including the registered agent address and principal details. On the tax side, the Commission may require the business to clear any outstanding tax liabilities or produce a Letter of Good Standing before reinstatement is complete. The Tax Commission issues Letters of Good Standing free through its online services.6Utah State Tax Commission. Online Services That letter is separate from the Certificate of Existence issued by the Division of Corporations, and some transactions call for both.
