Slack is experiencing some connectivity issues — please stand by. Check
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:
Add Slack's full name and address to your tax exempt certificate:
Slack Technologies, Inc. 500 Howard Street San Francisco, CA 94105 USA
Send your current and signed sales tax exempt certificate to firstname.lastname@example.org, and include your Slack URL (e.g., url.slack.com) in your message.
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.
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 Authorization Certificate are exempt from VAT, and we can help remove VAT from your purchase. Please send a copy of your VAT56B Authorization Certificate to email@example.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.
Effective January 1, 2019, VAT will be added to your purchase if the billing address associated with your Slack workspace or org is in Russia. Starting on this date, customers can provide their Tax Identification Number (TIN) to be included on billing statements and invoices.
Slack’s Tax Registration Reason Code (KPP) will be available once registration is completed in early 2019. Stay tuned!
Note: If your billing address is outside of the EU and Russia, you won't be charged VAT or a similar transaction tax.
Update tax info and business status
If your billing address is in Australia, the EU, Quebec (Canada), or Norway, update your billing info to include your Australian Business Number, Quebec Registration Number*, or VAT ID, as applicable, and select your business status.
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 won't be applied. You'll be responsible for self-assessing and payment VAT on purchases at the applicable rate of the country you're doing business in.
Non-business status: You don't use Slack for business purposes. If you select this option, standard VAT may be automatically applied based on your billing address. We reserve the right to change your status to Business if we learn your workspace is being used for business purposes.
*Beginning February 1, 2019, customers can provide their Quebec Registration Numbers, if applicable.
