Key Points

  • TaxJar simplifies sales tax calculation and filing for US-based Squarespace stores
  • Choose between TaxJar's automatic tax calculations or Squarespace's built-in feature
  • Ensure your plan supports the TaxJar features you need - both services require specific subscription levels
  • Connect TaxJar via Squarespace Extensions panel, then configure your business profile and tax settings
  • Add state registrations in TaxJar for accurate sales tax calculations at checkout
  • Disconnect TaxJar to revert to Squarespace's automatic tax settings

Understanding TaxJar Integration with Squarespace

TaxJar integrates with your Squarespace online store to manage sales tax calculations, reporting, and filings. This feature is only available for US-based sellers dealing with US taxes, designed to simplify the complex web of state and local tax regulations.

Choosing Your Plan

Both TaxJar and Squarespace require specific subscription plans depending on your needs. Here's what you need:
  • Tax Rate Calculations Only: Any Squarespace commerce plan + any paid TaxJar plan
  • Sales Tax Filing and Reporting: Any Squarespace commerce plan + any paid TaxJar plan (Professional Plan gives you full features)

Setting Up TaxJar on Your Squarespace Site

Connecting TaxJar to your Squarespace site takes a few steps, but it's straightforward if you follow the process.

Connect Your TaxJar Account

  1. Go to the Extensions panel on your Squarespace dashboard
  1. Find and connect to the TaxJar extension, then either sign in to your existing account or create a new one
  1. Fill in your email address, select 'Business profile' from the dropdown, and save your business information

Register Your Tax States

  1. In TaxJar, go to 'Add State Registrations'
  1. Add all the states where you have a business presence (nexus) and set up details for each
  1. Enable TaxJar's API to allow real-time tax rate calculations during checkout
Make sure you've added all registered states to avoid issues with tax collection at checkout.

Configure Additional Settings (Optional)

You can classify products under specific tax categories within Squarespace, tailoring tax rates based on product types. However, consult a tax professional if you're unsure about the applicable categories for your products.
Pixelhaze Tip: Always double-check that your TaxJar integration doesn't overlap with Squarespace's own automated taxes. Having both enabled could cause conflicts in tax calculations.

FAQs

How can I switch to Squarespace's built-in automated taxes? Disconnect TaxJar and then turn on automated taxes from the Taxes panel in Squarespace.
What if my tax setup shows as incomplete? This typically means not all business locations are registered. Check TaxJar and complete the necessary location settings.
Why didn't tax get charged on an order? Make sure the TaxJar connection is complete and relevant state settings are activated.

Jargon Buster

  • TaxJar: Automates sales tax calculations, filing, and reporting processes
  • Nexus: A legal term for the required presence of a business in a state that subjects it to state tax laws

Final Thoughts

Integrating TaxJar with your Squarespace site can significantly streamline your sales tax operations. It's a powerful tool for any US-based online store. Make sure you set it up properly by selecting appropriate plans, enabling required settings, and understanding concepts like nexus and tax categories. With everything in place, managing sales tax becomes much smoother, freeing you up to focus on growing your business.
