Managing indirect tax compliance around the world

Thousands of domestic and multinational corporations count on Thomson Reuters ONESOURCE for the only truly complete indirect tax solution — from research to determination and compliance.
 

Why choose ONESOURCE Determination

As your business grows, calculating, collecting, and reporting for global tax purposes gets more complicated. You need to accurately report on sales and use tax, goods and services (GST) tax, value-added tax (VAT)  and excise tax – no matter how often the rates or rules change. You also need to plan responses to market disruptors like changing economic nexus rules and tax regulations. Our cloud-based, global, tax determination software allows companies to automate tax calculations on transactions without the headache of managing and maintaining an in-house solution or reporting system. 65% of Fortune 500 companies and multinational corporations have relied on our global tax technology for more than a decade.  As a cloud-native application, our tax automation software minimizes the cost of scaling quickly to meet the needs of a  growing business, without the worry of downtime for updates.

We wanted to use a simple system, a single set of rules that the tax department could control — not IT and not the end user — to make sure that our tax liability was accurate.
