Sales and Use Tax Agreement
What a Sales and Use Tax Agreement Is and why it matters
Why documented tax allocation reduces exposure
A Sales and Use Tax Agreement reduces audit exposure, allocates financial responsibility for tax liabilities, clarifies resale certificate handling, and documents who must register and remit taxes. Clear agreements streamline compliance and lower the risk of disputes or unexpected tax assessments.
Who typically relies on these agreements
Sellers, purchasers, accounting, tax compliance, procurement, and legal teams use Sales and Use Tax Agreements to assign tax responsibilities and manage liability.
- Sellers: determine collection obligations, accept resale certificates, and remit taxes or assign liability.
- Buyers: provide valid resale certificates and accept responsibility for use tax where applicable.
- Tax and legal teams: review jurisdictional rules, draft indemnities, and manage audit responses.
Both small businesses and enterprises use them to support audit defense, document exempt sales, and clarify remittance duties.

- Accepting an incomplete or expired resale certificate without verification, which exposes the seller to tax liability and potential audit penalties.
- Failing to specify jurisdiction and choice of law, creating disputes over which state's tax rules apply to the transaction.
- Allocating tax responsibility ambiguously, leaving both parties exposed if a state determines tax was due and uncollected.
- Not updating agreements after nexus changes or legislative updates, causing noncompliance with new collection obligations.

FAQs and common eSignature issues for Sales and Use Tax Agreements
-
Can this be e-signed?
Yes. Electronic signatures are generally valid under the ESIGN Act (15 U.S.C. ch. 96) and UETA where adopted. Confirm exceptions such as wills, certain court filings, and state-specific exceptions before using e-signatures for those matters.
-
When is notarization required?
Most sales and use tax agreements do not require notarization. Notarization or RON may be necessary if the agreement includes sworn statements, affidavits, or state-specific formalities; check the state's notary rules before execution.
-
What if a resale certificate is missing?
If a valid resale certificate is not provided, the seller may be liable for unpaid sales tax, interest, and penalties. Sellers should either collect tax at the point of sale or document reasonable efforts to obtain the certificate and preserve communications for audit defense.
-
How long should I keep records?
Retain executed agreements and supporting resale certificates for at least three years per IRS guidance; industry or state rules may require longer retention — HIPAA requires six years for health records and some states require extended periods.
-
Who must sign the agreement?
An authorized officer, owner, or employee with explicit signature authority should sign. Print the signer's name and title, and retain corporate authorization or delegation documents to show signing authority if requested by auditors.
-
Can the agreement be amended later?
Yes. Amendments should be in writing, reference the original agreement, state an effective amendment date, and be signed by authorized representatives. Update attached resale certificates and notify tax or accounting teams of material changes.
