FAQs
1. What is sales tax automation software?
Software that handles your entire compliance workflow—calculations, product classifications, monitoring nexus, filing returns, remitting payments—without manual work. Connect once, stay compliant forever.
2. How quickly can we get started?
Most businesses see their tax liability in 3 minutes and are fully automated within two weeks. We import your existing registrations so nothing's lost.
3. What makes Kintsugi different?
True automation and AI. While others offer "tax services" Kintsugi uses AI to do the math, and human tax experts for support.. Plus a growing list of integrations that actually work.
4. How does pricing work?
Kintsugi is free to use, and $75 per automated action (filings and registrations). Month-to-month pricing with no annual contract lock-ins. We also offer fixed rate contracts for companies with higher sales volumes.
5. What happens if I ignore sales tax compliance?
States are getting aggressive. They're buying transaction data, hiring auditors, and sharing information. When they find you—and they will—you'll owe back taxes, penalties, and interest for every year you weren't compliant.
6. Why can't my accountant handle sales tax compliance?
They can file returns, but can they track nexus across 45 states? Calculate rates for 13,000 jurisdictions? Manage exemption certificates? Most CPAs refer sales tax compliance to specialists—like us.
