Once you have submitted your current tax-exempt certificate, Rio Grande will apply the most advantageous tax rates to your future purchases, which may include lower or no sales tax.
Please note: Although a tax-exempt certificate contains similar information to your business license, a business license is not a tax-exempt certificate.
