FAQs
What triggers sales tax compliance requirements?
Physical presence (office, employees, inventory) or economic nexus (typically $100,000 in sales or 200 transactions per state). Each state has different thresholds
What is the best software to use for sales taxes?
For sales tax specifically: Kintsugi for multi-channel sellers who want true automation; Avalara for Fortune 500 companies with complex international needs; Vertex for enterprises with existing ERPs.
What does compliance cost with Kintsugi?
$75 per filing or registration, or fixed monthly plans for higher volume. No per-transaction fees. Free compliance assessment to start.
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.
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.
We're already non-compliant. Is it too late?
No. Voluntary disclosure always beats involuntary discovery. We handle VDAs regularly, often reducing penalties by 75% or more. The sooner you address sales tax compliance, the better your outcome.
How is Kintsugi different from TaxJar or Avalara?
We automate everything, not just calculations. While they focus on enterprise complexity, we focus on actual automation. Connect once, stay compliant forever. No modules, add-ons, or implementation consultants required.
