Sales tax and VAT

Slack reserves the right to assess applicable taxes as required by local law. Depending on location, customers may be charged transaction taxes when purchasing the Pro, Business+ or Enterprise Grid subscription.

The basics

  • Your company address is used to determine the correct tax rate, if applicable.
  • Prices shown on our website do not include sales tax or value-added tax.
  • Workspace owners, or the person who upgraded a workspace, can update the company address and other billing details from the Billing page.


US sales tax

US customers may be subject to state and local sales taxes. The postal code entered for your company address will determine whether your workspace is subject to tax, and the applicable state and local tax rates. Sales tax charges will be included as a line item on your billing statement or invoice.

Business customers who provide an Australian Business Number (‘ABN’) and confirm that they are registered for GST in Australia will not have GST added to their future invoice.

When applicable, if a valid tax registration number is entered and VAT/GST has previously been charged on the invoices issued to you, then upon request by you, Slack may refund VAT/GST included on invoices issued in the ninety days prior to a valid tax ID being provided. However, VAT/GST will not be refunded on any invoices issued outside of this ninety-day period.

  • VAT/GST registered status: Your company is registered for VAT/GST in your country of operations. If you select this option, VAT/GST won't be applied, if applicable.
