Where can I see how much I am getting charged for sales tax each month?

If you are being charged sales tax, you will see it as a line item on your invoice. You’ll be able to find the new sales tax line item by navigating to Account Details in the Twilio SendGrid UI, then by viewing your invoice, which is in PDF form.


Can I get an estimate of my sales tax?

Unfortunately, we cannot provide estimates of sales tax for an individual customer ahead of time. The taxes assessed could change monthly for various reasons, such as state or local tax laws changing. You can check your bill throughout the month for an estimate of your sales tax.


Will my tax amount vary from month to month?

Taxes charged can vary month to month. This may be caused by a change to local tax laws, or if your product mix causes your bill to be higher or lower than it was in previous months.


How does Twilio SendGrid calculate the sales tax owed?

Tax laws change regularly, so we use third-party software that monitors local and state tax laws. Twilio SendGrid uses this software to calculate the sales tax you are charged each month.
