How does AI actually work in sales tax compliance? It's a question we hear often, and it deserves a straight answer.

Here's what we don’t do: use AI to calculate your taxes or validate filing accuracy. Tax calculations require precise, legally defensible rules, and probabilistic models don’t cut it. 

Here's where we do use AI: high-volume, rules-based tasks like nexus monitoring, transaction reconciliation, and risk scoring. Kintsugi Intelligence optimizes workflows and task routing to save your team hours every month, while humans stay in the loop for every decision that requires judgment. 

We believe in applying AI ethically, in the right places, to deliver real value to you and your clients.

Platform Updates

We’ve been hard at work behind the scenes, launching new countries, integrations and always enhancing the product and support experience. Kintsugi is now available in 100+ countries and supports 40+ integrations. Here’s a few to highlight:

🌍 New countries: We’ve launched in the United Kingdom, Turkey, UAE, Kenya, Nigeria, Armenia, China, and many more. 

🔗 New integrations: Rillet, Maxio, Orb Billing, Ordway, and Sage are now supported, making it easier to connect your existing tech stack and keep compliance running automatically.

🎉 Sales tax holiday support is now live. Kintsugi now automatically applies sales tax holiday rules to eligible transactions, so you don't have to manually track or adjust for temporary exemptions. Sales tax holidays are limited periods when states temporarily remove or reduce sales tax on certain purchases. They occur a few times per year, with the most common ones around back-to-school season in late July and August.

Success Stories

Pins & Aces, a Colorado-based golf brand, spent two years on a compliance platform that misfiled returns, failed to pull accurate Shopify data, and left them with over $10,000 in penalties. After switching to Kintsugi, they achieved day-one compliance, seamless Shopify integration, and now spend about two minutes per week on sales tax.

Regulatory Updates

Several changes took effect March 1, with Alabama launching massive changes across the board. Here’s what you need to know.

Ask Kintsugi

🤔 If a client uses a third-party fulfillment center like Amazon FBA, do they need to register in every state where inventory is being held?

💡 It depends. Storing inventory in some states creates physical nexus, which triggers a registration requirement. The Kintsugi team can help you sort where you have exposure. 

🤔 Does a client need to be registered in a state to issue a resale certificate? Can Kintsugi prepare resale certificates?

💡 Generally, yes. A valid resale certificate typically requires an active registration in the state where the purchase is being made. Kintsugi prepares resale certificates for premium plan clients.

Closing

Sales tax compliance should not cost you hours of manual work, unexpected penalties, or sleepless nights before a filing deadline. Kintsugi automates the complexity so you can focus on what actually moves your business forward.
