Global indirect tax challenges aren’t getting any easier

- Continued cost pressure on tax department
57% of tax departments expect signiﬁcant change to government requirements in the next 1-2 years 
Accuracy is foundational
Compliance is about the right answer. Innovation lets us get it faster— and multiply its value. Getting modern sales and use tax, VAT, and GST right means bringing content, business data, and calculation together in real time.
