Working with Avalara has been perfect. We rely on their expertise in so many ways — like using Avalara Tax Research to determine a product’s taxability in various jurisdictions. Being able to trust that expertise saves my team so much time, I don’t know how they could live without it.

Industry: Software

If it’s a question about drop shipping or a nexus threshold, whatever it is, I’ll type it into Avalara Tax Research. Usually the same day, I have an answer. That’s important when I’m being told, ‘We have an order that has to go out. Can you figure this out so we don’t have a delay?’ I love it.

FAQ

Avalara Tax Research is the only major tax research platform that is part of an end-to-end agentic compliance system. Thomson Reuters Checkpoint, Bloomberg Tax Research, and Wolters Kluwer CCH AnswerConnect are research-only libraries built primarily for CPA firms and tax attorneys, so once you find an answer you still have to act on it in another system. Vertex sells a tax engine and offers research only through partners or add-ons; it doesn’t have a native tax research product comparable to Avalara Tax Research. Avalara Tax Research goes further: Avi, the AI research assistant, is built into the same portal as Avalara AvaTax, Avalara Returns, Avalara Exemption Certificate Management, and Avalara Cross-Border, so the answer you find can be applied to a calculation, a return, an exemption rule, or an HS code in the same workflow. Every answer is backed by curated Avalara tax content with verifiable citations, not generic web data.

Avi for Tax Research is the AI research assistant, built into Avalara Tax Research and the Avalara Portal. You ask a sales tax, use tax, VAT, or cross-border tax question in plain English and Avi returns a clear yes/no or summary answer with citations to the underlying Avalara content in seconds. Avi is grounded, not generated from the open internet: It retrieves answers from curated Avalara tax content, including pre-answered tax questions covering all 50 U.S. states, the District of Columbia, and key global jurisdictions. As part of the broader Avalara Agentic Tax and Compliance™ platform, Avi is the lead orchestrator that can also delegate work to other Avalara AI agents for filing, exemption validation, classification, and notice management, with built-in checkpoints for human review and approval.

Yes. Avalara operates MCP servers that let third-party AI agents and large language models discover and call Avalara APIs, including the Avalara Tax Research content layer, using natural language. That means a copilot in your ERP, an internal LLM assistant, or a Google Gemini Enterprise agent can ask Avalara for a citation-backed tax answer and receive structured content back, not just a link. Developers can connect through Avalara MCP servers at developer.avalara.com, and partners can integrate Avi into the agentic workflows they’re building. This is a meaningful difference from competitor research products, which still require a human to sign in, search, and copy answers manually.

Yes. With Avalara Tax Research Standard or Premium, you can use the Contact Tax Expert feature to submit your question directly to the Avalara Tax Research team. You’ll get a timely, personalized response that you can save, share, and use to defend a position. The Avalara Tax Research team includes attorneys and seasoned indirect tax practitioners who maintain the underlying Avalara Tax Research content. Avalara Tax Research Essentials includes a limited number of expert inquiries per year. This combination of self-serve AI (Avi), the searchable Q&A library, and direct human escalation is intentional: Most questions get answered in seconds; the hardest questions still get a human expert.

Avalara Tax Research is built for audit readiness. Every answer is law-backed and includes citations, so you can document the basis for any past tax determination. Avalara Tax Research Standard and Premium include a history of tax laws and answers, so you can show the rule that applied on the date the transaction took place, not just the rule in effect today. Taxability charts can be exported and shared with auditors, internal stakeholders, or external advisors. Avalara Tax Research is also trusted by state and local governments, and customers report meaningful audit-prep efficiency improvements (a Forrester Total Economic Impact study commissioned by Avalara found a composite organization saved up to 34 hours per audit and improved audit prep efficiency by 85%). When you combine Avalara Tax Research with our Reporting AI agents, every reported number can be traced back to its source transaction. 

Yes. Avalara Tax Research provides U.S. sales and use tax content for all 50 states and the District of Columbia, plus VAT and cross-border content. In late 2025, Avalara expanded Avi for Tax Research with the Avalara trade and tariff library, so you can research duties, de minimis thresholds, country-specific VAT, and HS code classification in the same AI experience you use for U.S. sales and use tax. That means tax, finance, AP, and supply chain teams no longer need separate research subscriptions for domestic and international questions. Users can also look up the latest tariff rates for products or components to understand cost and risk exposure across sourcing decisions.

For most recurring sales and use tax research questions, yes. Customers tell us they use Avalara Tax Research to answer day-to-day questions about product taxability, exemption certificates, drop shipment rules, nexus, and jurisdiction-specific rate questions — work that previously went to outside tax counsel or Big Four advisors at billable rates. For deeper or unique questions, Avalara Tax Research Standard and Premium include a Contact Tax Expert feature so you can submit your question directly to the Avalara Tax Research team and receive a timely, expert response. The ROI shows up in two places: outside-firm fees you no longer need to incur, and the time your in-house team gets back. The Forrester Total Economic Impact study commissioned by Avalara found Avalara Tax Research users recaptured up to 90% of tax research time and 384 hours annually.
