Sales tax is charged on all orders shipped to Colorado. The current sales tax rate at our Boulder location is 8.36%.

If you’re in Colorado but have a tax-exempt status, please first register as a customer. Then, email a copy of your exemption certificate to info@modrobotics.com. We’ll apply the exemption to your account and reply to your email to let you know. At that point you will be able to place your order as normal, and tax won’t be added at checkout.

Sales tax is not charged on orders that ship outside of Colorado.
