LabJack collects sales tax for many USA jurisdictions as required by law. If your company/organization is tax exempt or a valid reseller, please Contact Us prior to purchasing online or include proof of tax exempt status at checkout.
If you paid us sales tax, but don't think you should have, you must request such a refund within 15 days of the transaction. Sales tax refunds are complicated from the get-go, but they are even worse after we send the money on to the government.
