Pennsylvania Proposed Tax Sourcing Rules Create Compliance Ambiguity for Streaming Subscriptions

Multistate streaming services face immediate risk of double taxation or audit adjustments if Pennsylvania classifies their subscriptions under different service categories with conflicting sourcing tests. As states move toward market-based sourcing, the lack of a uniform definition for digital customers complicates tax apportionment for providers with centralized billing but distributed user bases. The broader industry must watch the Independent Regulatory Review Commission's response by September 23, 2026, as it will signal whether the state will revert to the more detailed, license-count-based sourcing used in previous guidance.

The Pennsylvania proposal follows a broader legislative shift in the state’s corporate tax regime. Governor Tom Wolf signed House Bill 1342 in July 2022, which formally adopted market-based sourcing for receipts from intangibles and began a multi-year reduction of the corporate net income tax rate. Per Forvis Mazars in July 2022, this law codified the state's economic nexus threshold, creating a rebuttable presumption that any corporation with over $500,000 in Pennsylvania-sourced receipts has a filing requirement, regardless of physical presence. The current regulatory effort seeks to move these long-standing department policies into formal administrative code.

Nationally, Pennsylvania aligns with a significant trend toward market-based sourcing for digital services. According to Grant Thornton in June 2025, Arkansas enacted legislation adopting market-based sourcing for the 2026 tax year, though it notably allowed telecommunications and cable providers to elect to continue using cost-of-performance sourcing until 2035. Similarly, Indiana launched a tiered framework in February 2025 that sources digital revenue first to the benefit location and then to the customer billing address, per EY reporting. These state-level variations emphasize the fragmentation streaming companies face when quantifying their "market" across different jurisdictions.

While corporate income tax sourcing rules target how a company’s profit is apportioned, they are advancing alongside a surge in digital sales and use taxes. According to Holland & Knight and RSM in July 2026, California Governor Gavin Newsom recently signed Senate Bill 122, which extends sales and use tax to software-as-a-service (SaaS) and other digital products starting January 1, 2027. Unlike the corporate tax sourcing rules, the California law explicitly excludes streaming media and digital audiovisual works. This highlights a growing complexity for B2B streaming vendors, who must now distinguish between corporate income sourcing for their entire platform and potential sales tax obligations for specific digital toolsets.
