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 plan.

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.


U.S. sales tax

U.S. 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 LLC, a Salesforce company
    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) or Goods and Service Tax (GST) on electronic services. Whether you're charged VAT or GST on your purchases depends on your billing address and how you use Slack.


Australia

Australia GST may be added to your purchase if the billing address associated with your Slack workspace or organization is in Australia. Business customers who provide an Australian Business Number (“ABN”) and confirm they are registered for GST in Australia will not have GST added to their future invoice.

Slack is registered as a non-resident vendor under the Simplified GST regime. As such, Slack is required to collect GST on sales of electronic services to Australian customers who have not provided their ABN and confirmed they are registered for GST in Australia.


Canada

Effective July 1, 2021, Canada GST/HST will be added to your purchase if the billing address associated with your Slack workspace or organization is in Canada. Business customers who provide a GST/HST ID will not have GST/HST added to their invoice.

Provincial Sales Tax (PST) may also be added to your purchase if the billing address associated with your Slack workspace or organization is one of the following provinces in Canada: British Columbia, Manitoba, or Saskatchewan.

Sales into the following provinces will be charged with following PST tax rates in addition to the 5% GST rate, if applicable:

British Columbia – 7%
Manitoba – 7%
Saskatchewan – 6%

    Other customers in the EU (not in Ireland), may be exempt from VAT on their future invoices 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 Norway, United Arab Emirates, Saudi Arabia, or one of the countries above, you can update your billing info to include your VAT/GST number (or applicable local tax registration number), and select your business status or tax registration 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.).
