ONESOURCE Sales and Use Tax AI AI features and pricing (October 2026)

ONESOURCE Sales and Use Tax AI is a Thomson Reuters product for corporate tax departments and accounting firms that prepare US sales and use tax returns. AI agents prepare and validate return data and flag anomalies, with human review steps built in.

The product is part of the ONESOURCE tax suite and was made available on January 15, 2026. It connects to ERP and business systems, prepares and validates data, generates returns and supports electronic filing. Coverage spans more than 1,200 returns across the US, Canada and Puerto Rico and over 100 local jurisdictions, with e-filing in 33 states. Thomson Reuters, headquartered in Toronto, says the tool is meant for tax departments of all sizes and for accounting firms. The launch release cites up to 65 percent faster compliance, a figure from the vendor.

• Prepares and maps return dataAgentic AI imports transaction data from ERP and other business systems, validates it and maps it to the returns of each jurisdiction. The vendor says this cuts manual steps by up to 50 percent, which leaves tax staff more time to review exceptions.
• Detects anomalies continuouslyThe system monitors compliance data and flags anomalies as they appear, giving daily insights instead of only periodic reports. Tax teams can correct a mapping or data problem before it reaches a filed return.
• Keeps an auditable trailEvery automated action is recorded so it can be traced later, and customers configure review gates where a person must approve before the process continues. This helps when auditors or state authorities ask how a figure was produced.

• Part of the ONESOURCE suite, so it can sit alongside Thomson Reuters determination and other tax products already in use.
• Configurable human review gates are part of the design rather than an add-on.
• Covers returns in the US, Canada and Puerto Rico, with e-filing support in 33 US states.

Thomson Reuters released the product in January 2026 for US corporations and accounting firms; it covers more than 1,200 returns for the US, Canada and Puerto Rico and e-files in 33 states.
