How Xero sales tax works

What Xero does

Xero's US plans include automated sales tax powered by Avalara, which calculates tax on invoices across US jurisdictions. Xero also gives you sales tax reports and due-date tracking.

Where it stops

For filing, Xero points to Avalara's separate automated e-filing service, and notes the feature is best suited to businesses that invoice in Xero.

What Kintsugi adds

Kintsugi goes further. Its tax engine calculates sales tax on your Xero invoices in real time, it tracks nexus across the US and internationally from your invoices and credit notes, and it registers, files, and remits for you.
