AI Agent Sales Tax by State: The Complete 2026 Guide

Beardsley Rumble|2026-04-07|16 min read

When your AI agent buys compute in Texas, purchases data in New York, and accesses a SaaS platform in Washington, each transaction triggers a different sales tax obligation. There is no uniform federal classification for AI agent transactions. Every state makes its own rules.

This guide covers all 50 states plus the District of Columbia. For each jurisdiction, you will find the current sales tax rate, whether digital services are taxable, the economic nexus threshold, and any special rules that affect AI agent transactions specifically.

Last updated: July 23, 2026. All rates verified against state Department of Revenue sources. Recent 2026 changes reflected below: California S.B. 122 (signed June 29, 2026 — SaaS and prewritten software taxable from January 1, 2027), Colorado HB 26-1223 (signed June 4, 2026 — software becomes taxable tangible personal property on the same January 1, 2027 date), Chicago's Personal Property Lease Transaction Tax increase to 15%, and Kentucky's prewritten-software guidance for AI agent operators.

How AI Agent Transactions Are Classified

States classify AI agent transactions into categories like data processing, information services, digital automated services, or prewritten computer software. The classification determines whether the transaction is taxable and at what rate.

AgentTax maps every transaction to one of five work types — compute, research, content, consulting, and trading — and then resolves the applicable economic category per state. The result is a per-transaction, per-jurisdiction tax determination.

A word of caution on terminology before the tables. "Agent tax compliance" is not one phrase in tax law — it is four, and three of them are terms of art that attach duties to a person, not to software. A withholding agent, an enrolled agent, and a state-registered tax agent each carry obligations an autonomous agent cannot hold. Which one you mean changes who is liable for everything below: what "agent tax compliance" actually means, and which of the four owes the tax.

Try it yourself: Use the AgentTax API Playground to calculate tax on any AI agent transaction — no signup required.

This page is the per-state reference. If you want the tax computed rather than looked up, see calculating AI agent sales tax at the transaction — what is taxable by transaction type, when nexus creates an obligation, and how to get the amount back in one API call.

The Quick Summary

  • 5 states have no sales tax: Alaska, Delaware, Montana, New Hampshire, Oregon

  • 26 states + DC tax digital services: These states explicitly tax SaaS, data processing, cloud computing, or digital automated services

  • 23 states do not tax digital services: Arkansas, California, Florida, Georgia, Idaho, Illinois, Indiana, Kansas, Michigan, Minnesota, Missouri, Nebraska, Nevada, North Carolina, North Dakota, Oklahoma, Virginia, Wisconsin, Wyoming (and the 5 no-tax states above, minus Alaska which has local taxes). Note: California leaves this group on January 1, 2027 under S.B. 122 (see below). Updated August 2026: Arkansas, Idaho, Indiana, Kansas, Minnesota, North Carolina, Wisconsin, and Wyoming moved to this group after a primary-source re-verification — their statutes and revenue departments exempt remotely accessed software, and this guide previously overstated their reach. Nebraska and North Dakota moved in a follow-up August 2026 verification pass — both have closed taxing statutes that reach delivered software, not remote access.

  • Key special rules: Texas (80% taxable), California (S.B. 122 — SaaS taxable from Jan 1, 2027), Connecticut (1% data processing rate), Maryland (B2B/B2C split), Iowa (B2B digital exempt), Washington (SB 5814 expansion), Chicago (15% Personal Property Lease Transaction Tax on cloud/SaaS leases)

You do not have to track all of this by hand. AgentTax returns a per-transaction, per-state tax determination — rate, jurisdiction, classification, and audit trail — from a single API call across every jurisdiction below.

States With No Sales Tax

These five states do not levy a state sales tax. AI agent transactions in these states have no state-level sales tax obligation.

Alaska (AK) — No State Tax, But Local Taxes Apply


  • State rate: 0%

  • Digital services taxable: No

  • Special note: Alaska has no state sales tax, but municipalities can levy local sales taxes up to 7.5%. Juneau, Anchorage, and other cities have their own rates. If your agent transacts with buyers in Alaska municipalities, local tax may apply.

Delaware (DE) — No Sales Tax


  • State rate: 0%

  • Digital services taxable: No

Montana (MT) — No Sales Tax


  • State rate: 0%

  • Digital services taxable: No

  • Special note: Montana has a resort tax in certain tourist areas, but it does not apply to digital services.

New Hampshire (NH) — No Sales Tax


  • State rate: 0%

  • Digital services taxable: No

Oregon (OR) — No Sales Tax


  • State rate: 0%

  • Digital services taxable: No

States That Tax Digital Services

These 26 states plus DC explicitly tax some or all digital services. If your AI agent has economic nexus in these states (typically $100,000 in sales or 200 transactions), you must collect and remit sales tax on applicable transactions.

Alabama (AL)


  • State rate: 4.0%

  • Digital services taxable: Yes

  • Nexus threshold: $250,000

Arizona (AZ)


  • State rate: 5.6%

  • Digital services taxable: Yes

  • Nexus threshold: $100,000

Colorado (CO)


  • State rate: 2.9%

  • Digital services taxable: Yes

  • Nexus threshold: $100,000

  • Special note: Colorado has a complex local tax structure. Denver, Boulder, and other home-rule cities administer their own sales taxes separately from the state.

  • 2027 change — HB 26-1223: Colorado enacted HB 26-1223 (signed June 4, 2026), folding "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, effective January 1, 2027 (the same date as California's S.B. 122). 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.

Connecticut (CT)


  • State rate: 6.35% (standard) / 1% (data processing)

  • Digital services taxable: Yes

  • Nexus threshold: $100,000 or 200 transactions

  • Special rule: Connecticut taxes computer and data processing services at a reduced 1% rate under Conn. Gen. Stat. § 12-408(1)(D)(i) (the service is defined at § 12-407(a)(37)(A)). Electronically accessed prewritten software sold to consumers is taxed at the full 6.35% under § 12-407(a)(13)(B); the 1% rate applies to business purchases for business use and to true data processing. On a $10,000 compute purchase, the difference is $100 vs. $635.

District of Columbia (DC)


  • Rate: 6.0%

  • Digital services taxable: Yes

  • Nexus threshold: $100,000 or 200 transactions

Hawaii (HI)


  • State rate: 4.0% (General Excise Tax)

  • Digital services taxable: Yes

  • Nexus threshold: $100,000 or 200 transactions

  • Special note: Hawaii's GET is imposed on the seller's gross receipts, not passed to the buyer as a separate line item. The economic effect is similar to sales tax but the legal structure differs.

Iowa (IA)


  • State rate: 6.0%

  • Digital services taxable: Yes (B2C only)

  • Nexus threshold: $100,000

  • Special rule: Iowa exempts B2B digital service transactions by statute. If your AI agent is purchasing on behalf of a business entity, the transaction is exempt. B2C transactions remain taxable at the full rate.

Kentucky (KY)


  • State rate: 6.0%

  • Digital services taxable: Yes

  • Nexus threshold: $100,000 or 200 transactions

Louisiana (LA)


  • State rate: 4.45%

  • Digital services taxable: Yes

  • Nexus threshold: $100,000 or 200 transactions

Maine (ME)


  • State rate: 5.5%

  • Digital services taxable: Yes

  • Nexus threshold: $100,000 or 200 transactions

Maryland (MD)


  • State rate: 6.0%

  • Digital services taxable: Yes

  • Nexus threshold: $100,000 or 200 transactions

  • Special rule: Maryland applies a split rate for digital services: 3% for B2B transactions and 6% for B2C. This applies to data processing, information services, and digital services. AI agents purchasing on behalf of business entities pay the reduced 3% rate.

Massachusetts (MA)


  • State rate: 6.25%

  • Digital services taxable: Yes

  • Nexus threshold: $100,000

Mississippi (MS)


  • State rate: 7.0%

  • Digital services taxable: Yes

  • Nexus threshold: $250,000

New Jersey (NJ)


  • State rate: 6.625%

  • Digital services taxable: Yes (information services; remotely accessed SaaS itself is exempt)

  • Nexus threshold: $100,000 or 200 transactions

  • Special rule: Remotely accessed SaaS is not taxable in New Jersey — TB-72 (July 3, 2013) treats SaaS access as a non-enumerated service with no transfer of tangible personal property, and TAM 2013-10 reaches only downloadable prewritten software, not SaaS access. Information services remain taxable at 6.625%. Professional services remain exempt — but AI agent output is generally not classified as professional services under NJ law.

New Mexico (NM)


  • State rate: 4.875% (Gross Receipts Tax)

  • Digital services taxable: Yes

  • Nexus threshold: $100,000

  • Special note: New Mexico uses a Gross Receipts Tax rather than a traditional sales tax. Like Hawaii's GET, it is imposed on the seller.

New York (NY)


  • State rate: 4.0% (+ local rates up to 4.875%)

  • Digital services taxable: Yes

  • Nexus threshold: $500,000 and 100 transactions

  • Special rule: NY taxes SaaS and cloud computing as "prewritten computer software" under NY Tax Law Section 1101(b)(6). A January 2026 appellate ruling confirmed this classification even when software is delivered via the cloud and bundled with services. Combined state + local rates in NYC reach 8.875%.

Ohio (OH)


  • State rate: 5.75%

  • Digital services taxable: Yes

  • Nexus threshold: $100,000 or 200 transactions

Pennsylvania (PA)


  • State rate: 6.0%

  • Digital services taxable: Yes

  • Nexus threshold: $100,000

  • Special note: PA also levies a local services tax in some jurisdictions. Philadelphia adds 2% for a combined 8%.

Rhode Island (RI)


  • State rate: 7.0%

  • Digital services taxable: Yes

  • Nexus threshold: $100,000 or 200 transactions

South Carolina (SC)


  • State rate: 6.0%

  • Digital services taxable: Yes

  • Nexus threshold: $100,000

South Dakota (SD)


  • State rate: 4.2%

  • Digital services taxable: Yes

  • Nexus threshold: $100,000 or 200 transactions

  • Historical note: South Dakota v. Wayfair (2018) established the modern economic nexus standard. The thresholds above originate from this case.

Tennessee (TN)


  • State rate: 7.0%

  • Digital services taxable: Yes

  • Nexus threshold: $100,000

Texas (TX)


  • State rate: 6.25%

  • Digital services taxable: Yes

  • Nexus threshold: $500,000

  • Special rule: Texas taxes AI agent compute purchases as "data processing services" under TX Tax Code Section 151.351. However, only 80% of the charge is subject to tax — the other 20% is exempt by statute. On a $1,000 transaction, the effective tax is $50 (5.0%), not $62.50 (6.25%). Most generic tax calculators miss this distinction.

Utah (UT)


  • State rate: 6.1%

  • Digital services taxable: Yes

  • Nexus threshold: $100,000 or 200 transactions

Vermont (VT)


  • State rate: 6.0%

  • Digital services taxable: Yes

  • Nexus threshold: $100,000 or 200 transactions

Washington (WA)


  • State rate: 6.5% (B&O Tax)

  • Digital services taxable: Yes

  • Nexus threshold: $100,000

  • Special rule: Washington's SB 5814 expanded taxation of digital automated services in 2025. The grace period for existing contracts expired April 1, 2026. If your agents transact with WA-based buyers and you have economic nexus, B&O tax applies to those sales. Washington also has significant local tax add-ons.

West Virginia (WV)


  • State rate: 6.0%

  • Digital services taxable: Yes

  • Nexus threshold: $100,000 or 200 transactions

States That Do Not Tax Digital Services

These states either have no sales tax or do not apply their sales tax to digital services and SaaS. AI agent compute, data, and SaaS transactions in these states generally have no state sales tax obligation.

Arkansas (AR) — 6.5%


  • Digital services taxable: No

  • Nexus threshold: $100,000 or 200 transactions

  • Arkansas excludes electronically delivered software from tax by definition — A.C.A. § 26-52-304(a)(1) says computer software "does not include software that is delivered electronically or by load and leave" — and SaaS is not an enumerated service; DFA Revenue Legal Counsel opinions 20180901 and 20200903 say so directly. Watch the other edge: Arkansas taxes specified digital products — digital audio, video, and books, including streaming subscriptions (A.C.A. § 26-52-301(3)(C)(iii), base from Act 141 of 2017) — so delivered or subscription content is a different answer.

California (CA) — 7.25%


Digital services are not taxable under California law through December 31, 2026 — SaaS and cloud computing are not currently treated as taxable tangible personal property. That is changing. 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 / SaaS layer flips to taxable. 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.

Florida (FL) — 6.0%


Florida does not currently tax SaaS or digital services. The state considered a digital services tax in 2021 but did not enact it. AI agent transactions for compute, data, and SaaS are currently exempt.

Georgia (GA) — 4.0%


Georgia does not tax SaaS or digital services — cloud computing and digital automated services are not enumerated, and SaaS is expressly excluded from the digital-products tax (Ga. Comp. R. & Regs. 560-12-2-.118(5)(c)). But since January 1, 2024, SB 56 (O.C.G.A. § 48-8-30(a)(2)) taxes permanent-use digital downloads sold to end users — ebooks, music, video, games, artwork — at 4% plus local rates. Electronically delivered prewritten software remains exempt (§ 48-8-3(91)), and subscriptions conditioned on continued payment are outside the tax. Agents buying content downloads in Georgia owe tax; agents buying software or SaaS do not.

Idaho (ID) — 6.0%


  • Digital services taxable: No

  • Nexus threshold: $100,000

  • Idaho Code § 63-3616(b) excludes remotely accessed computer software from tangible personal property outright, alongside custom and electronically delivered software. Digital music, books, videos, and games with a permanent right of use are still taxable regardless of delivery method.

Illinois (IL) — 6.25%


Illinois does not tax SaaS at the state level. The Illinois DOR confirmed in 2026 that AI services delivered via the cloud without transfer of tangible personal property are not taxable. However, Chicago's Personal Property Lease Transaction Tax (PPLTT) — raised to 15% effective January 1, 2026 — applies to cloud computing, SaaS, and compute delivered as nonpossessory leases to Chicago (ZIP 606xx) buyers. AgentTax returns the 15% Chicago PPLTT automatically on those transactions (and does not stack the 6.25% state rate on top). Downloaded digital goods remain exempt in Illinois.

Indiana (IN) — 7.0%


  • Digital services taxable: No

  • Nexus threshold: $100,000 or 200 transactions

  • Indiana wrote the SaaS exemption into statute: Ind. Code § 6-2.5-4-16.7(b) says a transaction in which an end user licenses the right to remotely access prewritten software "does not constitute a retail transaction." DOR Sales Tax Information Bulletin #8 confirms remote access is not taxable, and Revenue Ruling 2026-04-RST applies it to a cloud-hosted platform. Downloaded prewritten software remains taxable — the exemption turns on remote access, not on being software.

Kansas (KS) — 6.5%


  • Digital services taxable: No

  • Nexus threshold: $100,000

  • Kansas taxes enumerated services only, and hosted software is not among them. KDOR Opinion Letter O-2012-001 puts it plainly: "tax isn't imposed on the service charges in the first place." Data processing and information services are likewise nontaxable per EDU-71R. Prewritten software delivered electronically is still taxable (K.S.A. 79-3603(s)).

Michigan (MI) — 6.0%


Michigan does not tax SaaS or digital services. The one digital item in its tax base is prewritten computer software, which is taxable when "delivered by any means" — including download (MCL 205.51a). Treasury's RAB 2023-10 confirms the flip side: a digital good that is not prewritten software is not subject to sales or use tax whether it is downloaded, streamed, or accessed by subscription — so ebooks, media, and dataset downloads stay untaxed.

Minnesota (MN) — 6.875%


  • Digital services taxable: No

  • Nexus threshold: $100,000 or 200 transactions

  • Minnesota Revenue's computer software guidance (Fact Sheet 134) is direct: subscriptions to use online-hosted software are not taxable. The flip side: Minnesota taxes digital products broadly, including subscription and less-than-permanent rights (Minn. Stat. § 297A.61 subds. 50–54), so delivered digital content is taxable even though hosted-software access is not.

Missouri (MO) — 4.225%


Missouri does not tax SaaS or most digital services.
  • On the ballot August 4, 2026: Amendment 5 would phase out the individual income tax and open the sales tax base to services, with AI platforms named explicitly. A yes vote does not change taxability immediately — it starts a legislative rewrite window of up to five years. See Missouri Amendment 5 and the AI platform tax timeline.

Nebraska (NE) — 5.5%


  • Digital services taxable: No

  • Nexus threshold: $100,000 or 200 transactions

  • Nebraska's taxing statute is a closed enumeration with no SaaS, cloud, or remote-access hook (Neb. Rev. Stat. § 77-2701.16) — software is taxable only when it is furnished or transferred to the customer, so access-only SaaS and cloud services are outside the base. Downloaded or otherwise transferred software remains taxable, and enumerated security services (including security-monitoring SaaS) are separately taxable.

Nevada (NV) — 6.85%


Nevada does not tax SaaS or digital services.

North Carolina (NC) — 4.75%


  • Digital services taxable: No

  • Nexus threshold: $100,000 or 200 transactions

  • North Carolina has no imposition statute reaching SaaS — it is neither tangible personal property nor "certain digital property," and G.S. 105-164.13(43), (43a), and (43b) exempt custom, enterprise-server, and component software. The trap for agents: certain digital property DOES tax electronically delivered reports, newsletters, and publications (G.S. 105-164.4(a)(1)b), so information output delivered as a report can be taxable even though the software access is not.

North Dakota (ND) — 5.0%


  • Digital services taxable: No

  • Nexus threshold: $100,000

  • North Dakota's taxing statute is a closed list with no SaaS or remote-access clause — it reaches prewritten software only when the software is actually delivered, electronically or by load-and-leave (N.D.C.C. § 57-39.2-02.1(1)(g)), and the state's own administrative rule treats computer time via terminal and reports from customer-furnished data as nontaxable services (N.D. Admin. Code § 81-04.1-03-11). Items delivered electronically are exempt outright (§ 57-39.2-04(54)) — but that exemption carves out prewritten software, so downloads stay taxable, and computer-compiled information products sold broadly are taxable too. No ND authority uses the word "SaaS," so the exemption rests on inference rather than an explicit state statement — a distinction that matters if the Tax Commissioner ever revisits remote access.

Oklahoma (OK) — 4.5%


Oklahoma does not tax SaaS or digital services.

Virginia (VA) — 5.3%


Virginia does not tax SaaS or digital services. The state applies sales tax to tangible personal property and certain enumerated services.

Wisconsin (WI) — 5.0%


  • Digital services taxable: No

  • Nexus threshold: $100,000

  • Wisconsin does not tax remote access to software running on the seller's equipment — Wis. Adm. Code Tax 11.71(3)(d) — and processing a client's data is a nontaxable service under Tax 11.71(3)(a). But Wisconsin taxes "additional digital goods" including electronically delivered newsletters, reports, and periodicals (Wis. Stat. § 77.52(1)(d); DOR Publication 240), so delivered content is a different answer than hosted access.

Wyoming (WY) — 4.0%


  • Digital services taxable: No

  • Nexus threshold: $100,000 or 200 transactions

  • The Wyoming DOR's Computer Sales and Services bulletin (revised February 2024) says it verbatim: SaaS, PaaS, and IaaS "are not subject to Wyoming sales tax" when the customer receives no tangible property or enumerated service. Any download or possession flips the transaction to taxable prewritten software — trackers that list Wyoming as taxing SaaS are conflating delivery with remote access.

What This Means for AI Agent Builders

If your AI agents transact across state lines — buying compute, accessing APIs, purchasing data, or using SaaS platforms — you likely have sales tax obligations in multiple states. The key factors are:

  • Economic nexus: Once you exceed a state's revenue or transaction threshold (typically $100,000 or 200 transactions), you must register, collect, and remit sales tax. Note that the transaction-count half of that test is disappearing — several states have repealed it since 2025, leaving revenue as the only trigger.

  • Transaction classification: The same transaction can be "data processing" in Texas, "prewritten software" in New York, and "digital automated service" in Washington. Classification determines taxability and rate.

  • B2B vs. B2C: Some states (Iowa, Maryland) treat B2B and B2C transactions differently. Whether your agent is acting for a business or an individual consumer affects the tax rate.

  • Local taxes: State rates are the floor. Local jurisdictions can add 1-5% more. New York City adds 4.5% to the state's 4%, for a combined 8.875%.

What to Do

  • Calculate per-transaction: Generic quarterly estimates are not sufficient. Each transaction needs a jurisdiction-specific tax determination at the time it occurs.

  • Track nexus thresholds: Monitor your revenue by state. As AI agent transaction volume grows, you will cross nexus thresholds in new states.

  • Maintain audit trails: Every tax determination should be documented with the rate, jurisdiction, classification, and confidence score.

Together, registering where you have nexus, classifying each transaction, and keeping a defensible audit trail are the core of agent tax compliance for autonomous commerce — with the caveat that the phrase itself carries four distinct meanings, and the duties in this guide land on the operator rather than on the agent.

AgentTax handles this automatically. One API call per transaction returns the tax amount, rate, jurisdiction, classification, and audit trail. Get your free API key (no credit card), compare plans and pricing, or try it in the playground first.
