Navigating the Rapid Expansion of Digital Taxation
The digital economy now dominates consumer and business spending. As such, states are responding by aggressively expanding sales and use tax bases to capture revenue from digital products and services. In our recent Advantous webinar, we explored what’s driving these changes, where states are heading, and the key compliance risks businesses should be watching.
Why Digital Taxation Is Expanding
States are facing revenue pressure as tangible goods represent a shrinking portion of taxable transactions. At the same time, SaaS, streaming, cloud computing, and digital services continue to grow. Legislatures are responding by:
-
- Expanding tax bases to include digital goods and services
- Reclassifying SaaS and cloud services as taxable
- Updating sourcing rules to reflect remote and multistate use
- Tightening enforcement through economic nexus standards
The result is a patchwork of rules that vary significantly by state.
The Core Challenges
Digital taxability often turns on classification:
-
- Is it a product or a service?
- Is it software, data processing, or information?
- Is the customer purchasing access or ownership?
Bundled transactions, such as SaaS combined with implementation or training, present additional risk. In many states, failure to separately state charges can cause the entire transaction to become taxable.
Sourcing is equally complex. Determining where a digital product is “used” or where the customer receives the benefit can vary by state, especially when multiple users or locations are involved.
Key State Developments
Several states enacted or expanded digital taxation in 2025 and beyond:
-
- Texas significantly revised its data processing rule (effective April 2025), expanding the tax base and shifting focus to what the seller does rather than the “essence of the transaction.” SaaS continues to be treated as taxable data processing, and new sourcing rules presume benefit in Texas unless proven otherwise.
- Louisiana broadened its tax base effective January 1, 2025, to include digital goods and software access services, while creating exemptions for certain business use, financial institutions, and healthcare providers.
- Washington expanded its tax base to include several professional and digital services, including advertising and IT services.
- Maryland implemented a 3% sales tax on data and IT services and continues to defend its digital advertising tax in litigation.
- Maine expanded its sales tax base to include digital audiovisual and audio works, including streaming services, effective January 1, 2026.
Proposed Legislation and Digital Advertising Taxes
Multiple states are considering further expansion, particularly targeting digital advertising and IT services. Proposals in Virginia, Utah, Nebraska, Tennessee, Rhode Island, and New York reflect a broader trend: states are looking beyond traditional goods and applying tax to digital consumption and service-based revenue models.
Digital advertising taxes, in particular, remain a hot-button issue and are facing constitutional challenges.
Federal Guardrails and Litigation
The Internet Tax Freedom Act (ITFA) continues to limit state authority by prohibiting:
-
- Taxes on internet access
- Multiple taxation of the same transaction
- Discriminatory treatment of electronic commerce
Ongoing litigation, including challenges to Maryland’s digital advertising tax, will shape how far states can go in taxing digital transactions.
What Businesses Should Do Now
With definitions evolving and sourcing rules tightening, businesses should:
-
- Reevaluate how digital products and services are classified
- Review bundled transactions and invoicing practices
- Assess multistate sourcing methodologies
- Monitor legislative and litigation developments
Digital taxation is no longer emerging policy, it is an active and expanding area of enforcement. Proactive planning and regular review are critical to managing risk in today’s multistate environment.
