All online orders will show tax charges. If you are tax exempt, enter the tax exempt number in the online order comments with a note that states that you are tax exempt and are sending in your tax exempt certificate. Then follow up with a fax of the tax-exempt certificate to 301.263.3017 or scan and email to taxdepartment@lwtears.com. Please be sure to note the online order's reference order ID so that we can locate your order. We will make sure that if we have the proper tax exempt information, we will not charge you tax.
