Sales tax and VAT

Slack reserves the right to assess applicable taxes as required by local law. Depending on their location, customers may be charged transaction taxes when purchasing the Standard, Plus or Enterprise Grid subscriptions.

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.

Request an exemption

If your company is tax exempt, please follow the steps below. 501(c)(3) status from the IRS is not sufficient proof of state or city sales tax exemption.

  1. Add Slack's full name and address to your tax exempt certificate:

    Slack Technologies, Inc.
    500 Howard Street
    San Francisco, CA 94105
    USA
  2. Send your current and signed sales tax exempt certificate to tax@slack.com, and include your Slack URL (e.g. url.slack.com) in your message.


Value-added tax

Slack will charge value-added tax (VAT) on electronic services. Whether you're charged VAT or consumption tax on your purchases depends on your billing address and how you use Slack.

Note: If your billing address is outside of the EU, Japan, South Africa, the Republic of Korea, Switzerland and Russia, you won't be charged VAT, JCT or a similar transaction tax.

EU

VAT will be added to your purchase if the billing address associated with your Slack workspace or org is in the EU. In Ireland, however, customers will be charged VAT unless an exemption applies.  VAT will be listed as a separate line item on billing statements and invoices.

Request an exemption

  • Ireland
    Customers with a VAT56B Authorisation Certificate are exempt from VAT, and we can help to remove VAT from your purchase. Please send a copy of your VAT56B Authorisation Certificate to tax@slack.com, and include your Slack URL (e.g. url.slack.com) in your message.
  • Other countries in the EU
    Other customers in the EU (not in Ireland), may be exempt from VAT when a valid VAT ID is entered on your Billing page. Learn how to update this information.

Update tax info and business status

If your billing address is in Australia, the EU, Quebec (Canada), South Africa, the Republic of Korea, Norway, Singapore, United Arab Emirates, Saudi Arabia or Chile, update your billing info to include your Australian Business Number, Quebec Registration Number, VAT ID, GST ID, Tax Registration Number (TRN) or Taxpayer ID Number (TIN) as applicable, and select your business status (if applicable).

  • Business status: You use Slack for business purposes and expect to receive revenue (e.g. corporations, affiliates, sole traders, self-employed merchants, partnerships, etc.). If you select this option, VAT/GST won't be applied. You'll be responsible for self-assessing and paying VAT/GST on purchases at the applicable rate of the country that you're doing business in.
  • Non-business status: You don't use Slack for business purposes. If you select this option, standard VAT/GST may be automatically applied based on your billing address. We reserve the right to change your status to Business if we learn that your workspace is being used for business purposes.
