Intermediate Quick Answer
Are resale certificates valid across multiple states?
⚡ TL;DR
State-issued resale certificates are valid only in the issuing state. For multi-state purchases, two options exist: the MTC Uniform Certificate (accepted in most states, with exceptions including California) and the SST Exemption Certificate (accepted across all 24 SST member states). Sellers must confirm their state accepts the form before honoring it.
State-issued resale certificates work only in the state that issued them. For multi-state buying, two standardized options exist: the MTC certificate and the SST Exemption Certificate.
Key takeaways
- State-issued resale certificates: valid only in the issuing state; a Texas resale certificate cannot be used to make an exempt purchase from a seller with nexus only in California
- MTC Uniform Sales and Use Tax Resale Certificate: a multi-state resale certificate accepted as a substitute for state-specific forms in most states; not universally accepted — CA, LA, and a few others have restrictions; the MTC maintains an acceptance list
- SST Exemption Certificate: the standardized certificate for the 24 SST member states; a single certificate accepted across all SST states for the same buyer; sellers enrolled in SST automatically accept it
- Seller’s obligation: verify that the certificate type presented is accepted in the state where the sale originates (the state where the seller has nexus); if unsure, require the buyer’s state-specific form
- Buyer’s obligation: obtain the correct certificate type for the seller’s nexus states; for national distributors, this often means maintaining MTC or SST certificates plus state-specific certs for the holdout states
- Best practice for buyers: for sellers who won’t accept MTC, obtain state-specific certificates for each state where purchases will occur; this is often part of vendor onboarding for large B2B buyers
Frequently asked questions
Can I use one resale certificate to make exempt purchases in multiple states?
Not with most state-issued certificates. Each state's certificate is typically valid only in that state. However, two multi-state options exist: the MTC (Multistate Tax Commission) Uniform Sales and Use Tax Resale Certificate is accepted in most states as an alternative to state-specific forms; and the SST Exemption Certificate is accepted by all 24 SST member states. Sellers must confirm which certificates their state of sale accepts before honoring them.
Does my state accept the MTC Uniform Resale Certificate?
Most states accept the MTC certificate but some have restrictions — California, for example, does not accept it; Louisiana and Massachusetts have specific requirements. Before accepting an MTC certificate from a buyer, check whether the destination state where you have nexus honors it. Your tax software documentation or the MTC's own acceptance chart lists which states accept the form and under what conditions.
