Tax compliance software

Make indirect tax your strategic advantage 

Prepare returns faster, with fewer errors, and gain complete audit transparency with AI-powered tax compliance software — built to help tax teams across thousands of jurisdictions worldwide

Compliance complexity is outpacing manual processes

Indirect tax compliance is becoming more digital, more complex, and more unforgiving due to:

Thousands of jurisdictions with constantly changing U.S. sales and use tax rules

Global digitization mandates for VAT, SAFT, S-II, and near-real-time reporting

Fragmented data across enterprise resource planning (ERP), general ledger (GL), billing, and e-commerce systems

Tight filing windows with increasing audit scrutiny

Our approach: AI that works with you, not against you

ONESOURCE combines agentic AI with predictable automation and human oversight to handle the full compliance life cycle — without sacrificing control or auditability.

Frequently asked questions

What is the difference between sales tax compliance software and global tax compliance software?

Sales tax compliance software typically focuses on U.S. state and local sales and use tax obligations, including return preparation, validation, and filing. Global tax compliance software supports international indirect-tax requirements, including VAT, GST, digital reporting, listings, and country-specific filing formats across multiple jurisdictions.

How does AI help with tax compliance?

AI helps identify anomalies, classify exceptions, suggest or apply approved corrections, accelerate reconciliations, and reduce repetitive manual tasks. In ONESOURCE, AI is combined with predictable automation and human controls to support explainability, transparency, and auditability.

Who should use sales tax compliance software?

Sales tax compliance software is ideal for corporations with U.S. sales and use tax filing obligations, especially those managing large filing volumes, multiple jurisdictions, or complex compliance requirements. It is also useful for firms and enterprises seeking to reduce manual return preparation and filing efforts.

Who should use global tax compliance software?

Global tax compliance software is designed for multinational organizations that manage VAT, GST, SAFT, SII, listings, and other international indirect tax obligations. It is especially valuable for teams operating across multiple countries, systems, and digital reporting frameworks.
