Do States Tax SaaS? A 50-State Guide for 2026
Last updated: July 24, 2026 — California S.B. 122 and Colorado HB 26-1223 are both enacted and both take effect January 1, 2027. Two states in this guide's exempt column are on a timer.
If you sell AI services, cloud software, or any form of digital product, the single most confusing question in tax compliance is: Is my product taxable in this state?
The answer depends entirely on how each state classifies what you're selling. And the classifications are wildly inconsistent. As of 2026, approximately 25 U.S. jurisdictions tax some form of SaaS, though the specific rules vary dramatically from one to the next (Ordway Labs, February 2026; TaxCloud, January 2026).
This guide gives you the full 2026 picture — organized by how states approach digital product taxation, with specific notes relevant to AI builders.
Read the exempt table with a calendar in hand. Two of the largest states in it, California and Colorado, enacted laws in June 2026 that make prewritten software and SaaS taxable effective January 1, 2027. They are exempt as you read this and taxable on New Year's Day. See the January 1, 2027 cliff below.
Why SaaS Taxability Is So Complicated
U.S. sales tax was designed for physical goods. The legal frameworks were written decades ago around tangible personal property — things you can hold in your hands. When software emerged, states had to decide: is it tangible property (taxable) or an intangible service (often exempt)?
For boxed software sold on a CD, most states said "tangible, taxable." When software moved to downloads, many states followed along. But when software moved to the cloud — accessed via browser, never downloaded, never installed — the classification became genuinely ambiguous (TaxJar, December 2025; Anrok).
Different states resolved this ambiguity in completely different ways:
- Some treat SaaS as equivalent to tangible software: taxable
- Some treat SaaS as a non-enumerated service: exempt
- Some created new categories like "data processing service" or "digital automated service" with their own rules: it depends
- Some distinguish between business and consumer use: taxable for one, exempt for the other
The result is a patchwork that defies simple categorization. But here's our best effort.
States That Tax SaaS (Fully or Substantially)
These states treat SaaS as taxable — either as tangible personal property, prewritten software, or an enumerated digital product. If you have nexus here and sell digital services, you almost certainly need to collect.
| State | Rate | Classification | Notes |
|---|---|---|---|
| Arizona | 5.6% | TPP | Transaction Privilege Tax applies |
| Connecticut | 6.35% / 1% | Digital good | 1% rate for business use; full rate for personal (TaxJar, December 2025) |
| Hawaii | 4.0% | Service | GET applies to virtually all services |
| Iowa | 6.0% | Specified digital product | Taxable for consumers; exempt for business customers |
| Kentucky | 6.0% | Digital property | Explicit SaaS taxation |
| Louisiana | 5.0% | Digital product | Rate increased from 4.45% to 5.0% as of January 2025 |
| Maryland | 3.0% / 6.0% | Data/digital service | Split-rate system (July 2025). SaaS purchased solely for use in an enterprise computer system: 3% "tech tax" (NAICS 518, 519, 5415, 5132). Anything else, including individual use: 6%. Per Technical Bulletin No. 56 the axis is USE, not buyer status — a business buyer whose purchase is not solely enterprise-system use is on the 6% side |
| Massachusetts | 6.25% | TPP | Prewritten software, regardless of delivery method |
| New Mexico | 5.0% | Service | Gross Receipts Tax applies broadly |
| New York | 4.0% | Prewritten software | SaaS taxed as prewritten software, fully taxable |
| Ohio | 5.75% | Computer service | Taxable as "automatic data processing" or electronic information services, only when provided for use in business (R.C. 5739.01(B)(3)(e)); consumer purchases are exempt |
| Pennsylvania | 6.0% | Software | Canned software taxable regardless of delivery |
| Rhode Island | 7.0% | Software | SaaS treated as prewritten software |
| South Carolina | 6.0% | Communication | Taxable as communication service |
| South Dakota | 4.5% | Digital product | Broadly taxes electronic products |
| Tennessee | 7.0% | Software | SaaS taxable as software |
| Texas | 6.25% | Data processing | 80% of charge taxable as "data processing service" — effective rate 5.0% (TaxJar, December 2025) |
| Utah | 6.35% min | Software | Taxable as seller-hosted prewritten software since July 1, 2026 — full Utah guide |
| Washington | 6.5% | Digital product | SaaS taxable as digital automated service |
| West Virginia | 6.0% | Service/software | Broadly taxes services including SaaS |
| D.C. | 6.0% | Digital good | Increasing to 7.0% for digital goods/services October 1, 2026 |
States That Exempt SaaS (Generally)
These states generally do not tax SaaS, either because they classify it as a non-taxable service, haven't legislated on it, or have explicit exemptions:
| State | Rate | Why Exempt |
|---|---|---|
| Alabama | 4.0% | SaaS not specifically enumerated as taxable |
| Arkansas | 6.5% | Cloud-based software generally not taxable |
| California | 7.25% | Exempt through December 31, 2026 only. No tangible property transferred; SaaS treated as a non-taxable service (Ordway Labs, 2026). S.B. 122 makes prewritten software and SaaS taxable January 1, 2027 |
| Colorado | 2.9% | Exempt through December 31, 2026 only. SaaS generally not taxable at state level (but local jurisdictions vary significantly). HB 26-1223 folds computer software into taxable TPP January 1, 2027 |
| Florida | 6.0% | SaaS exempt; no tangible property changes hands |
| Georgia | 4.0% | SaaS not specifically taxed |
| Idaho | 6.0% | SaaS generally exempt |
| Illinois | 6.25% | SaaS exempt at state level (but Chicago imposes a 15% lease tax — see local issues below) |
| Indiana | 7.0% | SaaS exempt by statute — Ind. Code § 6-2.5-4-16.7(b): remote access to prewritten software "does not constitute a retail transaction." Downloaded software and permanent-use digital audio/video/books remain taxable |
| Kansas | 6.5% | Remote access to software generally not taxed |
| Michigan | 6.0% | SaaS generally exempt |
| Minnesota | 6.875% | SaaS generally not taxed |
| Mississippi | 7.0% | Since July 1, 2023, software on a server outside Mississippi and accessible only via the internet "is not a taxable retail sale" (Miss. Code § 27-65-7, 2023 SB 2449). Software on an in-state server, or code delivered to the buyer, stays taxable |
| Missouri | 4.225% | SaaS exempt; no tangible property |
| Nebraska | 5.5% | Access-only SaaS and cloud services are outside the closed enumeration of taxable services (Neb. Rev. Stat. § 77-2701.16) — software is taxable only when furnished or transferred, so downloaded software remains taxable |
| Nevada | 6.85% | SaaS generally exempt |
| New Jersey | 6.625% | SaaS exempt when accessed remotely |
| North Carolina | 4.75% | SaaS generally not taxable |
| North Dakota | 5.0% | Closed taxing list has no remote-access clause; software is taxed only when actually delivered (N.D.C.C. § 57-39.2-02.1(1)(g)), and the state's admin rule calls computer time via terminal a nontaxable service. Software downloads stay taxable |
| Oklahoma | 4.5% | SaaS not specifically enumerated |
| Virginia | 5.3% | SaaS exempt |
| Wisconsin | 5.0% | SaaS generally exempt (downloaded software is taxable) |
| Wyoming | 4.0% | SaaS generally exempt |
States With No Sales Tax
| State | Notes |
|---|---|
| Alaska | No state tax, but local jurisdictions may tax. ARSSTC applies to remote sellers in participating boroughs (TaxCloud, January 2026) |
| Delaware | No sales tax |
| Montana | No state sales tax (some resort jurisdictions have local taxes) |
| New Hampshire | No sales tax |
| Oregon | No sales tax |
Critical 2026 Updates
Several changes took effect or were announced for 2026 that AI builders should track:
Maine added digital audiovisual and digital audio services to its taxable category for 2026. SaaS and streaming businesses may need to update product taxability (TaxCloud, "Sales Tax Changes 2026," December 2025).
D.C. will increase its tax rate on digital goods and services from 6.0% to 7.0% effective October 1, 2026.
Illinois eliminated its 200-transaction economic nexus threshold effective January 1, 2026, moving to a $100,000 revenue-only threshold (TaxCloud, December 2025).
Louisiana increased its state sales tax rate from 4.45% to 5.0% as part of a broader tax reform package effective January 2025, which carries into 2026.
Utah codified "seller-hosted prewritten computer software" by name in S.B. 162, effective July 1, 2026, moving SaaS taxability out of administrative guidance and into the statute.
The January 1, 2027 Cliff
Two states in the exempt table above are exempt only until the end of this year. Both laws are enacted — not proposed, not pending — and both take effect the same day.
California — S.B. 122, signed by Governor Newsom on June 29, 2026, extends California sales and use tax to prewritten software and SaaS at the 7.25% state rate effective January 1, 2027. The law excludes custom software, raw IaaS/compute, digital assets, and pure information services; only the prewritten-software and SaaS layer flips. If your agent delivers a SaaS or packaged-software product to California buyers, plan for taxability starting in 2027. Full analysis: California's SaaS tax signed into law.
Colorado — HB 26-1223, signed June 4, 2026, folds "computer software" — delivered by any means, including download and remote access — into taxable tangible personal property at the 2.9% state rate plus home-rule local tax, also effective January 1, 2027. The agent-relevant trap is the exemption: Colorado's negotiable-license carve-out expressly excludes "click-through agreements, online terms of service, and other boilerplate" — exactly how an autonomous agent acquires software. Where California's exclusions turn on what the software is, Colorado's decisive one turns on how the deal is papered. Full analysis: Why Colorado HB 1223 hits AI agents harder than California.
Why this matters more than a normal rate change: California and Colorado are not marginal jurisdictions. If you have economic nexus in either — and a high-volume agent crosses the $100,000 threshold faster than most operators expect — a product that is correctly exempt on December 31 is a collection obligation on January 1, with no invoice or pricing change to prompt you. Audit exposure starts accruing immediately.
California's S.B. 122 change is already carried in the AgentTax engine as an effective-dated rule, so /api/v1/calculate returns exempt for a 2026 transaction date and flags the S.B. 122 treatment for a 2027 one. Colorado's HB 26-1223 is not yet effective-dated in the engine; until it is, treat a 2027-dated Colorado software transaction as taxable and verify against the statute rather than relying on the API default.
The Local Jurisdiction Problem
State-level rules are only part of the picture. Several states allow local jurisdictions to impose their own tax rules that may differ from the state:
Colorado has "home rule" cities that set their own tax rules independently. Over 60 Colorado cities act as independent taxing authorities (OurTaxPartner, 2026). Denver may tax something that the state of Colorado doesn't.
Illinois — Chicago imposes a Personal Property Lease Transaction Tax that applies to SaaS, even though SaaS is exempt at the state level. The rate rose from 9% to 15% on January 1, 2026 (Chicago Mun. Code ch. 3-32). A streamed media subscription (video, music or games) takes Chicago's 10.25% Amusement Tax instead (Mun. Code § 4-156-020(A)(2)). (Updated September 30, 2026: this entry previously gave the pre-2026 9% rate.)
Alaska — Individual boroughs can levy their own sales taxes and may include digital services.
What This Means for AI Builders
If you sell AI services — inference APIs, compute, agent labor, SaaS tools — you need to classify your product under each state's framework. The same product might be:
- A "data processing service" in Texas (80% taxable)
- "Prewritten software" in New York (fully taxable)
- A "non-taxable service" in California (exempt through December 31, 2026 — taxable from January 1, 2027 under S.B. 122)
- A "digital automated service" in Washington (fully taxable)
- Somewhere in a gray area in a dozen other states
AgentTax classifies AI transactions into six types — compute, API access, data purchase, SaaS, AI agent labor, and storage — and maps each to a tax category (digital service, digital good, or general service) per state. The /api/v1/calculate endpoint handles this classification automatically so your agent doesn't have to.
Staying Current
SaaS taxability laws change frequently. States are actively expanding digital taxation as they seek new revenue sources. What's exempt today may be taxable next year — California and Colorado are the proof, and both dates are already on the calendar.
For the agent-specific version of this analysis — nexus, classification, and per-state collection duties for autonomous transactions — see the AI agent sales tax 50-state guide and the AI agent sales tax pillar.
AgentTax's rate database is verified against Tax Foundation data (as of January 1, 2026) and cross-referenced with TaxJar, TaxCloud, and the Sales Tax Institute. Our /api/v1/rates endpoint returns current rates and taxability status for any state, and our /api/v1/verify endpoint lets other AI systems independently verify our data.
Build your agents to check taxability dynamically, not to hardcode assumptions. The rules will change. Your code shouldn't have to.
