Managing sales tax compliance across multiple e-commerce platforms like Shopify, Amazon, and Etsy can be overwhelming for sellers. Each platform has different rules, transaction flows, and reporting formats. Integrating a robust sales tax software solution can streamline tax collection, filing, and remittance, saving you time and reducing the risk of non-compliance.
PEAK Business Consultancy Services, a tax consultancy based in India, works with U.S. CPA firms and e-commerce businesses to manage complex sales tax filing across platforms. Learn more about our sales tax support and outsourcing services.
Why Sales Tax Integration Matters
States have implemented economic nexus rules, making it mandatory for out-of-state sellers to collect and remit sales tax once they hit certain thresholds. Manual tracking and filing are no longer sustainable. Sales tax software integration allows for:
- Real-time tax calculation based on customer location
- Automated reporting and filings across multiple states
- Audit trail with jurisdiction-wise breakdowns
- Reduced risk of undercollection or overcollection
Step-by-Step: Integrating Sales Tax Software with Shopify
- Choose a Sales Tax Software: Popular options include Avalara, TaxJar, and Sovos. Verify that the software supports Shopify integration.
- Install the App: Go to the Shopify App Store and install the relevant plugin (e.g., TaxJar Sales Tax Automation).
- Connect Shopify to the App: Grant permissions for access to orders, customer data, and product details.
- Configure Nexus Settings: Indicate states where you have nexus and set up the jurisdictions where tax needs to be collected.
- Enable Auto Filing (optional): Many tools offer automatic filing to state portals—verify filing frequency and due dates.
- Test Transactions: Run test sales to ensure correct tax rates are applied and properly recorded.
Integrating with Amazon Seller Central
Amazon offers built-in tax collection under its Marketplace Facilitator Laws, but you still need integration for reporting accuracy and filing in non-facilitated states:
- Log into Your Tax Software: Choose a tool that supports Amazon (e.g., Avalara or TaxJar).
- Link Amazon Account: Through OAuth or API keys, grant access to your sales and transaction history.
- Import Historical Data: Backfill up to 12-24 months of transaction data for accurate filings.
- Review Amazon Nexus Rules: Amazon collects and remits for most states, but ensure your software doesn’t double-report in those jurisdictions.
- Generate Reports: Use the software dashboard to generate monthly, quarterly, or annual sales tax summaries.
PEAK Business Consultancy Services can assist e-commerce sellers and CPA firms with Amazon sales tax reconciliation, ensuring no overpayment or filing discrepancies. Speak to our advisors today.
Integrating with Etsy
Etsy also complies with marketplace facilitator laws and handles collection in most U.S. states. However, your responsibility includes proper record-keeping and remitting in states not covered.
- Select Compatible Software: Choose one that supports Etsy API integration, such as TaxJar or Avalara.
- Connect Etsy Shop: Use OAuth login to authorize your Etsy shop with the software dashboard.
- Confirm Marketplace Collections: Mark Etsy as a marketplace facilitator within your software to exclude tax already collected and remitted.
- Generate Nexus Alerts: Software tools monitor when you hit economic nexus thresholds in new states.
- Map Products & Categories: Ensure that the taxability codes of your products are correctly mapped to state definitions (e.g., clothing exemptions).
Choosing the Right Sales Tax Software
Here are a few comparisons of the most commonly used platforms:
- Avalara: Comprehensive, robust, supports global compliance, best for mid-size and enterprise-level businesses.
- TaxJar: Easy to use, designed for small to mid-sized businesses, strong Shopify and Etsy integrations.
- Sovos: Corporate-grade solution, ideal for multi-entity sellers and complex reporting needs.
