If your diesel repair shop, fleet operation, or agricultural business qualifies for sales tax exemption, you should not be paying tax on the parts you resell or use in exempt operations. Valley Fuel Injection & Turbo makes it easy to set up tax-exempt purchasing on your account — submit your certificate once and every qualifying order is tax-free going forward.

Who Qualifies for Tax-Exempt Purchasing?

  • Diesel repair shops purchasing parts for resale (with valid resale permit)
  • Agricultural operations with farm exemption certificates
  • Government agencies (federal, state, and local)
  • Nonprofit organizations with valid 501(c) exemption
  • Manufacturers purchasing components for production

Not sure if you qualify? Contact us and we will help you figure it out.

What to Submit

To set up tax-exempt purchasing on your trade account, we need:

  1. Completed exemption form (below) with your business details
  2. Tax ID or EIN
  3. State-issued exemption certificate (resale permit, ag exemption, government exemption letter, etc.)
Pro Tip:
Have your certificate ready as a PDF, JPG, or PNG file before starting the form. Most states let you download a copy from your tax authority’s website.

Submit Your Tax Exempt Certificate












    Multi-State Purchases

    If your business operates in multiple states, you may need to submit a certificate for each state where you claim exemption. California resale permits are accepted for all purchases shipped to California addresses. For out-of-state shipments, provide the exemption certificate for the destination state.

    Compliance Note:
    Tax-exempt certificates must be current and valid. Expired certificates will need to be renewed before we can continue processing tax-free orders. We may periodically request updated documentation to maintain compliance with state tax regulations.
