Jan 8, 2025
The OneSource Tax Provision has the ability to perform calculations and provide updates on regulations. This prevents me from sharing tax information with you and reduces the number of tools you can use to analyze tax.

OneSource Tax Provision had a simplified data entry and calculation system which was much more efficient than the manual process. Another added advantage was the real-time tax rate updates, which made it easy for me to get the right tax provision calculations.

Like

- It will do the job eventually

Like

Easy to use and quick

Dislike

I've encountered discrepancies between the software's calculations and our final tax liabilities. This has created a lot of last minute changes in provisions and trying to justify the variances at the end of the quarter.

Dislike

Regarding Transfer pricing module: - Not efficient to work with - Not user-friendly - Buggy in some cases

Dislike

It is slow at times and may not have all the relevant information and Implementation time is very long
