SaaS vs. Digital Downloads
In 2026, states like Maine have expanded taxes to digital audio/visual downloads but still maintain an exemption for SaaS accessed remotely. If your platform allows users to download a desktop client, you may inadvertently trigger "Tangible Property" status in otherwise exempt states.
B2B vs. B2C Sourcing
For B2B SaaS, the "Benefit of Use" rule often applies. If a company buys 1,000 licenses but only 200 are used in a taxable state like New York, you may be able to apportion the tax. In 2026, auditors are increasingly looking for Multi-State Benefit (MSB) certificates to justify partial tax collection.
