Is SaaS taxable in New York, and where is it used?

What is taxable, and what the invoice can separate

The platform subscription is the core taxable item: the recurring fee for access to the software, however the invoice denominates its quantity, months, seats, or a single annual line. Around it cluster charges that New York does not generally tax when they are distinct and separately stated: professional services, consulting, implementation work that is not itself the sale of software, and similar service lines. Custom research and analysis belongs on that list only subject to the information services rule discussed below. Two disciplines keep the distinction alive.

The first is separation on the invoice, and it rests on statute rather than on examiner habit. Services performed on computer software are exempt from the services tax, but where they are provided to a customer in conjunction with a sale of tangible personal property, which includes prewritten software, the charge is exempt only when it is reasonable and separately stated on an invoice or other statement of the price given to the purchaser (Tax Law section 1115(o)). A single bundled price for platform plus services forfeits that condition. Where software and services are sold together, the Tax Appeals Tribunal in the Beeline matter asked whether the software license was incidental to the services rendered or was itself what the customer bought, and the Appellate Division accepted that inquiry as the functional equivalent of the primary function test used to classify services. Separately stated service charges, priced with commercial reality, are what let the service lines keep their own character.

The second is consistency of description. Relabeling the platform fee as a service does not change what the customer is buying, and descriptions on invoices are the first thing an auditor reads. The seller's product catalog, contracts, and invoices should tell one consistent story about which lines are access to software and which are human work.

Custom software has its own statutory rule. Software designed and developed to the specifications of a specific purchaser is not prewritten software, though it becomes prewritten when sold to anyone other than that purchaser (Tax Law section 1101(b)(14)). Prewritten software modified to one purchaser's specifications remains prewritten software. Where the modification carries a reasonable, separately stated charge on an invoice or other statement of the price, the modification itself is not prewritten software (Tax Law section 1101(b)(14)). A configured instance of a standard product is still prewritten software: in Beeline, the Appellate Division held it rational for the Tribunal to conclude that software tailored to clients' needs was not designed and developed to the specifications of a specific purchaser (Matter of Beeline.com, Inc. v. State of New York Tax Appeals Tribunal (3d Dept 2026) 2026 NY Slip Op 00175).

One of those service lines deserves more caution than the list above implies, because it has its own taxing provision. Tax Law section 1105(c)(1) imposes tax on the furnishing of information, which the statute defines to include the services of collecting, compiling or analyzing information of any kind and furnishing reports of that information. The exclusion that bears on most platform output is narrow: information that is personal or individual in nature and that is not, or may not be, substantially incorporated in reports furnished to other persons. The statute also excludes the services of advertising or other agents, or other persons acting in a representative capacity; information services used by newspapers, electronic news services, and radio and television broadcasters in the collection and dissemination of news; and meteorological services (Tax Law section 1105(c)(1)). A line item labeled custom research and analysis therefore does not fall outside the tax because of its label. It falls outside under the personal-or-individual exclusion only if what the customer receives is personal or individual and is not reusable in reports furnished to anyone else, which is a demanding description of most platform analytics, benchmarking output, and market data work.

The Court of Appeals has upheld the Tribunal on both conditions of that exclusion. In Matter of Wegmans Food Markets, Inc. v. Tax Appeals Tribunal (2019) 33 NY3d 587, it applied the presumption in favor of the taxing power to the exclusion and upheld as rational the Tribunal's finding that competitive price reports compiled for one customer from non-confidential shelf prices were not personal or individual in nature; the court did not reach the second condition. In Matter of Dynamic Logic, Inc. v. Tax Appeals Tribunal (N.Y. Ct. App., No. 35, April 17, 2025), it upheld the Tribunal's conclusion that advertising-effectiveness data reincorporated into benchmarking reports sold to others was substantially incorporated in reports furnished to other persons, so the exclusion did not apply. For classifying a service as an information service, the Department asks what the primary function of the service is, the analysis set out in Technical Memorandum TSB-M-10(7)S (July 19, 2010); that memorandum addresses information services, not software. The practical consequence for a platform seller is that separating a research or analysis line in the belief that services are exempt can still produce an assessment, on the information services theory rather than the software theory, where the line is compiled information delivered through the platform. Separation on the invoice remains worth doing; it establishes what each charge is, not that the charge is exempt.

The user-location measure, and the billing-address trap

Where a customer's employees use the software both inside and outside New York, the Department's guidance taxes the portion of the receipt attributable to New York users, which makes the seat map the tax base. The rule rests on guidance rather than statute. Tax Bulletin ST-128 cites no statute or regulation for it and describes itself as an informational document that is not intended to replace the law or change its meaning, and Tax Law section 1111 contains no software or user-location rule. The Department's advisory opinions apply the same users' portion rule (for example, TSB-A-08(62)S and TSB-A-24(8)S), but each binds the Department only as to the petitioner that requested it.

Many billing systems do not capture the seat map. Invoices carry a bill-to address, often a procurement office or headquarters with no relationship to where the licensed users sit, and both the seller's exposure and the seller's over-collection risk flow from treating that address as the answer. Two patterns follow. The seller that never collected anywhere discovers its New York-billed accounts and assumes the worst, though a documented user-level analysis can pull much of the base out of state. The seller that collected on billing address discovers it has been taxing customers whose users are elsewhere while missing customers billed elsewhere whose users are in New York.

The out-of-state share comes out of the base only on proof. Receipts are presumed taxable, and the burden of proving that a receipt is not taxable is on the person required to collect the tax or on the customer (Tax Law section 1132(c)(1)). In Matter of NetVoyage Corp. (Tax Appeals Tribunal, DTA No. 850246, August 27, 2026), the Division computed the audit from New York billings and said in writing that it would accept a breakdown of users in and outside the state. It rejected the seller's list of customers' office locations because the list did not account for the number of employees in New York versus outside New York. The Tribunal, affirming the administrative law judge, held that the seller had failed to prove that it was entitled to an apportionment. A billing-address audit was the Division's starting point in NetVoyage, and the seller that cannot produce user-level evidence keeps it.

The fix is contractual and administrative rather than legal. At sale, the order form or invoice can require the customer to state where the software will be used, as a percentage or seat allocation by state, and the seller should retain those declarations with the same care as resale certificates. No statute gives a use-location declaration the protection that Tax Law section 1132(c)(1) gives a properly completed resale or exemption certificate, so the declaration is evidence rather than a safe harbor. It is, however, the evidence the Division asked for in NetVoyage: a customer's contemporaneous statement of where its users sit is the document that both sets the collection and supports it later. Within New York, the same data sets the local rate, which follows the location from which the customer uses or directs the use of the software (Tax Bulletin ST-128). Retrospectively, in an audit that has already arrived, the same information is gathered by customer letters, and the companion article on New York software audits covers that machinery, the verification letters that support removing substantiated out-of-state use and customer-paid use tax from an assessment, in detail.

Assessment, refund, and appeal

The look-back is set by the limitations rule, not by the first sale. A seller whose only tie to New York is its sales becomes a vendor required to register and collect when, in the immediately preceding four quarterly periods ending on the last day of February, May, August and November, it had gross receipts over $500,000 from sales of property delivered in the state and made more than 100 such sales (Tax Law section 1101(b)(8)(i)(E) and (iv)). Where no return has been filed, the tax may be assessed at any time; otherwise the assessment period is generally three years from the filing of the return, extendable by written consent (Tax Law section 1147(b) and (c)). That open period for a non-filer is what keeps voluntary disclosure worth considering for a seller that is behind.

A notice of determination becomes an assessment unless the taxpayer applies to the Division of Tax Appeals for a hearing within 90 days of its mailing; a request for a conciliation conference with the Bureau of Conciliation and Mediation Services suspends that period (Tax Law sections 1138(a)(1) and 170(3-a)(b)). Late filing or payment carries a penalty of 10 percent of the tax for the first month plus 1 percent for each additional month, up to 30 percent, which is waived where the failure was due to reasonable cause and not willful neglect (Tax Law section 1145(a)(1)(i) and (iii)).

Over-collection on billing address creates refund claims of its own. A customer charged tax on users outside New York may apply for a refund within three years after the date the tax was payable by the seller to the Department, and a seller may obtain a refund of tax it collected only after establishing that it has repaid the tax to the customer (Tax Law section 1139(a)).

Practice notes

The compliance architecture for a SaaS seller with New York accounts has four pieces, each modest in cost relative to the assessment it prevents. Nexus comes first: post-Wayfair economic thresholds can create the New York collection obligation before anyone at the seller has looked, and because a non-filer's assessment period does not close (Tax Law section 1147(b)), voluntary disclosure stays on the table for the seller that is behind. Product taxonomy comes second: a standing memo mapping every SKU and invoice line to taxable software, taxable information service, or nontaxable service, applied consistently in billing, so that the taxability of the catalog is a decision made once rather than invoice by invoice. User-location capture comes third: the declaration at sale, refreshed on renewal for accounts whose footprint moves, with the arithmetic applied to collection and the declarations kept as the evidence NetVoyage shows the Division will ask for. Invoice hygiene comes last: separate statement of service lines at reasonable prices, quantity fields that mean something, and descriptions an auditor can read without a meeting, because in a receipts tax the invoice is the return's supporting schedule whether or not anyone designed it that way. The seller that builds these four pieces has converted New York from its worst audit exposure into a computation; the seller that builds none of them meets the same rules in the audit posture the companion article describes.
