Thomson Reuters ONESOURCE Tax Provision software calculates corporate tax estimates in seconds, and lets you quickly review data with filtering and drill-down capabilities. Plus, you can easily move data from tax provision to other direct tax solutions, so you only have to enter it once. Automation during the tax provision process results in more efficiency across the tax lifecycle. Which means closing faster, filing earlier, and freeing up time to grow your business.
