Is a VAT addendum enforceable electronically?

Yes. Electronic signatures are generally enforceable under the federal ESIGN Act (15 U.S.C. §7001) and UETA where adopted, provided intent, consent, attribution, and reliable record retention are present.

Does the U.S. have VAT rules?

No. The United States uses sales and use tax systems rather than VAT; VAT obligations arise under foreign jurisdiction law and must be handled per that jurisdiction's requirements.

What happens if the wrong VAT rate is applied?

Incorrect VAT application can lead to local tax interest, penalties, audit adjustments, and contractual indemnities; update invoices promptly and consult tax counsel for retroactive corrections.

Who should sign the addendum?

An authorized representative with contract-signing authority should sign. The document should state signer capacity and retain evidence of authority to reduce later challenges.

Are notarization or witnesses usually required?

Not typically for commercial VAT addenda, but domestic authentication rules vary by state; use notarization or witnesses if local law or contract governance requires them.

What records should be stored after signing?

Retain the executed addendum, original invoices, exemption certificates, import/export documents, and electronic audit trails for at least the federal minimum and longer where jurisdictional rules require.

FINANCIAL VAT ADDENDUM

This Financial VAT Addendum ("Addendum") is entered into as of Effective Date: by and between:

Client Name: Supplier Name:

Reference Agreement Date: (the "Agreement").

Purpose

The parties intend to clarify the treatment, invoicing, collection and remittance of value added tax (VAT) applicable to supplies of goods and services under the Agreement. This Addendum modifies the Agreement solely as to VAT matters set forth herein; all other terms of the Agreement remain in full force and effect.

Definitions

In this Addendum, "VAT" means any value added tax, goods and services tax or similar consumption tax (including related penalties, interest and additions) imposed by any taxing authority. "Tax Invoice" means an invoice that meets statutory VAT invoice requirements of the relevant jurisdiction.

VAT Registration and Contacts

Client VAT Registration Number Client VAT Contact (Tax Department) Supplier VAT Registration Number Supplier VAT Contact (Tax Department)

VAT Treatment

The parties agree the VAT treatment set out below will apply to supplies under the Agreement unless amended in writing by both parties.

Prices are quoted exclusive of VAT (Supplier will add VAT where applicable).

Prices are quoted inclusive of VAT (Supplier is responsible for remitting VAT out of the amounts invoiced).

Reverse charge applies: Client is liable for VAT under reverse charge rules where applicable; Supplier shall issue an invoice stating reverse charge has been applied.

Invoicing and Payment

Supplier shall issue a Tax Invoice that contains all information required by the jurisdiction of supply, including Supplier VAT Registration Number, Client VAT Registration Number (where applicable), a clear VAT amount or notation of reverse charge, and any statutory references required to support zero-rating or exemption claims.

Invoice Requirements (if additional)

Payment shall be made net of VAT where the invoice is VAT exclusive. Where prices are VAT inclusive, the Supplier shall separately state the VAT element. Late or disputed VAT items will be resolved without delaying undisputed payment obligations.

Adjustments, Credits and Audits

If any adjustment, assessment or correction by a tax authority results in additional VAT being payable or recoverable in respect of supplies under the Agreement, the party responsible for charging or collecting such VAT shall promptly notify the other party and the parties shall cooperate to effect any necessary credit notes, debit notes or refunds. Each party shall retain records and invoices for the period required by applicable VAT law and shall permit the other party reasonable access for audit purposes upon reasonable prior notice.

Indemnity and Liability

Each party shall indemnify and hold harmless the other party from and against any liabilities, costs (including reasonable professional fees), penalties, interest and taxes arising from its failure to account for or remit VAT or other related taxes when such failure is due to its act or omission.

Notification of Changes

Either party shall notify the other in writing within ten (10) business days of any change to its VAT registration status or any change in law that materially affects VAT treatment of supplies under the Agreement.

What the Financial VAT Addendum Covers

A Financial VAT Addendum is a contract supplement that allocates responsibility for value-added tax (VAT) or similar consumption taxes when parties operate across jurisdictions that impose VAT. It specifies how VAT is calculated, invoiced, and paid, clarifies which party bears the tax, and sets procedures for accounting adjustments, refunds, and documentation needed to support VAT recovery or exemption claims. For U.S.-based entities the addendum commonly appears in agreements with foreign suppliers or customers and should align with local VAT law in the relevant non-U.S. jurisdiction and with U.S. tax recordkeeping practices.

Why a VAT Addendum Matters to Financial Accuracy

A clear VAT addendum prevents unexpected tax charges, protects recoverability of input taxes, and reduces disputes over price changes when cross-border VAT applies. It provides contractual certainty about invoicing, documentation, and indemnities while supporting compliance with electronic recordkeeping laws such as ESIGN and state UETA frameworks.

Who Typically Prepares and Signs a VAT Addendum

The Financial VAT Addendum is used by contracting parties engaged in cross-border trade, service agreements, and procurement where VAT or similar taxes may apply.

Exporting or importing businesses that must allocate VAT responsibility between buyer and seller for invoicing and recovery.
Finance and accounts payable teams managing tax gross-up clauses, withholding, and refund procedures for international transactions.
Legal and procurement professionals who include tax indemnities, audit cooperation, and pricing adjustments in master agreements.

Parties should ensure authorized signatories execute the addendum and that accounting retains supporting records to substantiate VAT positions.

Invoice Issue Date:

Issue invoices per contract and local VAT rules to support VAT claim timing.

Payment Terms:

Payment due dates follow contract; VAT due dates follow local tax law.
