Form ST-930: Certification of Tax Status for Telephony and Telegraphy Services

Form ST-930, issued by the New York State Department of Taxation and Finance, is a certification document used to establish the tax status of information or entertainment services provided through telephony or telegraphy, or through telephone or telegraph services. In plain terms, it’s a way for a purchaser to formally tell a vendor whether the service being bought is subject to New York sales tax or qualifies for an exemption under state law.

New York taxes certain telecommunications services, but the rules get complicated when a service involves information or entertainment content delivered over phone lines — think of pay-per-call information lines, entertainment hotlines, or similar dial-up services. Because the taxability depends on how the service is classified, the state needs a documented way for buyers and sellers to agree on that classification before the transaction is billed. That’s exactly what Form ST-930 does.

Who Needs This Form

Form ST-930 is typically used by businesses or organizations that purchase information or entertainment services delivered via telephony or telegraphy for resale, or by vendors who need documentation to support the tax treatment applied to a customer’s account. If you operate a business that resells telecommunications-based services, or if you’re a service provider trying to determine whether to charge sales tax on a particular offering, this certification helps clarify the transaction’s tax status upfront.

It’s also relevant for accounting and compliance staff at telecommunications companies, since incorrect tax treatment on these services can lead to audit issues down the line. Having a properly completed ST-930 on file gives both the vendor and the purchaser a paper trail showing that the tax status was reviewed and certified at the time of the transaction.

When the Form Is Used

This certification generally comes into play at the start of a business relationship involving telephony or telegraph-based information or entertainment services, or whenever there’s a change in how a service is classified for tax purposes. Vendors may request it from purchasers before setting up billing, especially if the purchaser claims the transaction should be treated differently than the default taxable rate. Because tax rules for telecommunications services can shift with regulatory updates, some businesses also complete a new ST-930 periodically to keep their records current.

Like other New York sales tax certifications — similar in spirit to how Form TP-385 certifies residential energy use for tax purposes — ST-930 exists to document a specific factual claim that affects how tax is calculated and collected. The state relies on these certifications to keep vendors from having to make tax status determinations entirely on their own, shifting some of that responsibility (and the burden of proof) to the purchaser.

How to Get and Complete the Form

Form ST-930 is available directly from the New York State Department of Taxation and Finance as a fillable PDF, which means you can complete it digitally on your computer before printing it for signature or submission. The form asks for basic identifying information about the business, details about the service being certified, and a declaration regarding its tax status. Since it’s a certification document, accuracy matters — the person signing is attesting to the classification under penalty of the state’s tax fraud statutes.

Once completed, the form is generally kept on file by the vendor rather than mailed directly to the Department of Taxation and Finance, similar to how exemption certificates work for other specialized transactions. If you’re unfamiliar with how New York handles these vendor-purchaser certifications, it can help to look at other exemption-related forms, such as the ST-860 exemption certificate for guide and service dogs, which follows a similar documentation logic even though the subject matter is different. For businesses dealing with recaptured tax benefits or other specialized sales tax situations, the ST-65 IDA report is another example of how New York uses targeted forms to track specific tax circumstances.

Before submitting or relying on Form ST-930, double-check that the service description matches how the New York tax code defines information and entertainment services under the telephony and telegraphy provisions. If there’s any ambiguity about classification, it’s worth confirming with a tax professional or directly with the Department of Taxation and Finance before finalizing the certification.
