Accept Payments with Sales Tax Automation

Automate sales tax calculation, collection, and remittance for every transaction.

Why Sales Tax Automation Matters

The US has over 13,000 tax jurisdictions, each with different rates, rules, and filing requirements. After the 2018 South Dakota v. Wayfair Supreme Court decision, online sellers have sales tax obligations in states where they have economic nexus, even without physical presence.

Manual tax compliance is impractical for any business selling in multiple states. Tax automation platforms calculate the correct rate for every transaction based on the ship-to address, product category, and applicable exemptions.

How Tax Automation Integrates with Payments

Tax automation plugs into your payment gateway or e-commerce platform. When a customer checks out, the tax engine determines the correct tax rate in real time, adds it to the transaction total, and records it for filing.

Integration options include API-based calculation for custom checkout flows, plugins for Shopify, WooCommerce, and other platforms, and POS integration for in-person transactions.

Filing and Remittance

Beyond calculation, tax automation platforms handle filing returns and remitting taxes to each jurisdiction on your schedule. This eliminates the risk of late filings, missed jurisdictions, and penalty assessments.

Most platforms provide a single dashboard showing your tax obligations across all states, with automated filing at the correct frequency (monthly, quarterly, or annually depending on the state).

Frequently Asked Questions

Do I need to collect sales tax for online sales?

If you have economic nexus in a state (typically $100,000+ in sales or 200+ transactions), you are required to collect and remit sales tax in that state. Tax automation determines where you have nexus.

How much does sales tax automation cost?

Tax automation platforms typically cost $50 to $500 per month depending on transaction volume and features. This is far less than the penalties for non-compliance or the cost of manual tax management.

Does sales tax automation handle exemptions?

Yes. Tax automation platforms manage exemption certificates, tax-exempt customer profiles, and product-specific exemptions. Exempt transactions are properly documented for audit purposes.

What is economic nexus?

Economic nexus means you have a tax collection obligation in a state based on your sales volume there, even without physical presence. Thresholds vary by state but are typically $100,000 in sales or 200 transactions.

Can tax automation file returns for me?

Yes. Most platforms offer automated filing and remittance to all required jurisdictions. Returns are filed on the correct schedule with the correct amounts, eliminating late filing penalties.
