Sales tax and VAT software for Squarespace

Yes, on the Core, Plus, Advanced, Business, Commerce Basic and Commerce Advanced plans. Automated tax rates cover US sales tax, EU and UK VAT including the EU One Stop Shop, and GST, and they handle US tax holidays and item-level exceptions such as New York clothing under 110 dollars when the product carries the right tax code. The fee is 0.15% per transaction on Business and Core, 0.10% on Plus and Commerce Basic, and 0.05% on Advanced and Commerce Advanced, capped at 0.99 dollars. The limit is scope: it calculates only where you have already added a tax registration, and Squarespace states your store will not charge tax if the customer's address falls outside your registered regions.

By the billing postal code tied to the member's payment method. Squarespace applies that rule to both Digital Products pricing plans and Member Sites memberships, while physical products use the shipping address and local pickup uses the taxation address unless you set a taxation address. Its accounting export excludes the billing address on digital products, because they do not collect that information. That matters because digital goods taxability varies by state and by EU member state, and a postal code without a country is thin evidence for a return. Commenda holds the ship-to jurisdiction and a product tax code on every line, so a course, a download, and a shirt are each taxed the way that jurisdiction taxes them.

Not on its own. Squarespace states that a subscription product renews using the tax rate from the original order, and that it recalculates taxes only when you reprice the subscription. Changing the renewal frequency or the product name does not trigger a recalculation, and neither does a rate change in the customer's jurisdiction. Commenda calculates each period's liability against the rate in force for that period, so a state or member state rate change flows into the next renewal without you repricing the product.

No. Squarespace states it is not possible to exempt certain customers from paying sales tax, and its VAT guide repeats it for VAT. There is no customer-level exemption on manual rates or on automated ones. Product tax codes can make an item non-taxable for everybody, which is a different thing. Commenda applies the exemption at the customer level: the certificate is validated on upload, stored against that customer, and applied automatically in the states where it is valid, with expiries tracked. Where you need the exemption reflected at checkout, our API returns the rate for that customer and that address.

Squarespace recommends its own automated taxes and states that TaxJar's automatic calculations conflict with them. The two cannot run at once: connecting TaxJar disables automated taxes and limits collection to the United States, and disconnecting restores your earlier rates. TaxJar is the only one of the two that files, on a paid TaxJar plan, and Squarespace supports only connecting and disconnecting the extension. Commenda does both jobs in one place, US sales tax alongside EU VAT and GST, without turning off the calculation you already rely on.
