In an effort to become tax compliant, Heroku will be charging taxes on invoices to customers in certain states on August 1, 2019. Some customers may be tax exempt and should not pay these taxes.
Customers who are tax exempt must submit a copy of their Tax Exemption Certificate in a ticket to Heroku Support under the Billing category.
Please note, only teams can be marked as tax exempt. If you currently have your apps on a personal account, you'll need to create a team account and transfer your applications to the team account. Please review our documentation on Heroku Teams if you have any questions. You can reference our documentation on transferring applications here.
