Frequently Asked Questions about Tax Engagement Terms
-
Are electronic signatures legally valid
Yes. Electronic signatures are generally enforceable under the federal ESIGN Act (15 U.S.C. ch. 96, 2000) and state UETA laws adopted in most states; confirm exceptions such as wills or certain court filings.
-
What if the signer lacks authority
Verify signer authority in the engagement and require a title/authority statement. If authority is later disputed, the agreement may be voidable for lack of capacity or authorization.
-
When is notarization required
Notarization is rarely required for engagement letters but may be needed for related powers of attorney or state-specific declarations; check state notary rules before requiring notarization.
-
How long must I keep signed copies
Retain signed engagement terms at least three years; tax, HIPAA, or industry rules can extend retention periods (see IRC §6501(a), 45 CFR §164.530(j)).
-
Can a client revoke consent to e-delivery
Yes. For consumer-facing records, ESIGN requires a disclosure and a way for the consumer to withdraw consent; document the withdrawal process and revert to paper delivery if requested.
-
What causes IRS backup withholding
Providing an incorrect or missing TIN on a W-9 can trigger backup withholding at the statutory 24% rate; ensure accurate TIN collection and verification to avoid withholding.
