Are e-signatures legally binding?

Yes. Electronic signatures are legally binding under the ESIGN Act (15 U.S.C. ch. 96) and UETA where adopted, provided intent, consent, attribution, and record retention requirements are met.

Do I need a wet signature or notary?

Most tax engagement confirmations do not require notarization; exceptions exist by state or transaction type. Use notarization or RON where a state or third party specifically requires it.

What if the client’s TIN is incorrect?

An incorrect TIN can trigger IRS mismatch notices and backup withholding. Obtain corrected TIN immediately and consider submitting Form W-9 corrections to avoid penalties.

Can someone sign on behalf of a taxpayer?

Yes if they have valid power of attorney or legal authority. Attach the POA document and capture signer capacity in the signature block to document authority.

How do I correct a signed package?

If a package requires correction, create an amendment or corrected form, obtain fresh signatures, and retain both the original and corrected versions with a clear audit trail.

What security features should I verify in a signing service?

Confirm TLS 1.2/1.3 in transit, AES-256 at rest, detailed audit trails, and availability of BAAs for HIPAA-covered data; these features support compliance and evidence preservation.

What the Tax Client Confirmation Package Is

The Tax Client Confirmation Package is a standardized packet used by tax professionals to collect and verify client identity, tax identification numbers, engagement terms, document authorizations, and required supporting materials. It typically combines data-entry fields, checklists, consent statements, and signature blocks to confirm the taxpayer’s information and permissions needed to prepare or file returns. The package documents client acceptance of engagement terms, permission to obtain prior-year transcripts where applicable, and explicit consent for electronic delivery and e-signature under federal law.

Why a Formal Confirmation Package Matters

A complete confirmation package reduces errors, documents client consent, and creates an audit trail for tax preparers and clients. It clarifies responsibilities, preserves evidence of disclosure and authorization, and helps meet IRS and professional recordkeeping expectations.

Who Typically Uses the Tax Client Confirmation Package

Tax preparers, CPAs, enrolled agents, bookkeeping services, and payroll providers use this package to standardize client intake and compliance.

Independent tax preparers and small CPA firms consolidating client onboarding and consent procedures.
Bookkeeping and payroll providers confirming authorization to exchange tax data and prepare returns.
Large tax practices and enterprise finance teams using templates to meet audit and retention needs.

Use the package to reduce rework, establish a defensible record of client instructions, and to streamline e-signature and delivery workflows.
