Illinois imposes a statewide sales tax of 6.25% with local jurisdictions able to add additional rates. Remote sellers with over $100,000 in sales must register and collect tax, and exemption claims require an STAX-1 certificate. Filing can be done electronically via My Tax Illinois or on paper using forms ST‑1, ST‑2, and ST‑44.

Utah has enacted legislation extending sales and use tax to a broad range of digital products and subscription-based services effective 1 July 2026. The new rules tax payments for access to digital audio/video, streaming, gaming, e‑books, music, SaaS, and cloud‑hosted software, with a 4.7 % rate and a $100,000 remote‑seller threshold. Existing services under the Multi‑Channel Video or Audio Service Tax Act remain exempt to avoid double taxation.
