Integration: Built and supported by Miva, certified by Avalara

Sales tax can be a burdensome part of doing business, but getting it wrong puts your business at risk for large fines and penalties. Fortunately, automating compliance is easier than you may think. Avalara AvaTax connects directly to Miva software and applies the latest rates, saving you time, money, and effort.


AvaTax applies sales tax and VAT calculations at the point of purchase. Centralized, secure management enables tax schedules for new locations to be assigned and maintained automatically.


AvaTax integrates seamlessly with multiple business systems, maintaining data continuity across teams. Rates are calculated and applied “behind the scenes,” without disrupting user flow or burdening your IT or finance teams. On-demand reporting gives you the information you need for returns or audits.


Forget about updating tax tables, monitoring rule changes, and scheduling tax holidays. AvaTax continuously updates data, applying the latest rates available for over 12,000 U.S. sales tax jurisdictions. With advanced address validation, sourcing and taxability determination, and jurisdiction assignment technology, you’ll improve rate accuracy while reducing audit risk.


AvaTax is a scalable, subscription SaaS solution, with pricing based on each customer’s needs. The cloud-based service eliminates additional hardware costs and allows your IT and finance teams to focus on work that adds value and grows your business.
