Frequently asked questions and troubleshooting
-
Signer name and TIN do not match IRS records
If a name/TIN mismatch occurs you may receive an IRS CP2100 series notice and the payer could be required to apply backup withholding at 24%. Correct the form promptly, obtain the correct TIN, and resubmit; use IRS TIN-matching tools when available.
-
Are electronic signatures legally valid for this form under U.S. law
Yes. The ESIGN Act (15 U.S.C. §7001) and state UETA statutes (adopted by 49 states) give electronic signatures legal effect when intent, consent, attribution, and retention requirements are met; certain exceptions like wills or court filings remain excluded.
-
When is notarization required for the Tax Code Application Form
Most payer-facing tax documents do not require notarization. If a payer or state law demands a notarized certification, follow the payer’s instructions and confirm remote notarization availability with the state notary commission.
-
How do I correct the information after submission
Provide a corrected form to the payer immediately and request the payer file a corrected information return with the IRS if an incorrect return was submitted. Keep dated copies of both originals and corrected versions for your records.
-
What authentication level should I require for signers
Apply an authentication level appropriate to risk: email link for low risk, SMS or two-factor for higher risk, and knowledge-based or government ID checks for sensitive tax or high-value transactions to strengthen attribution and non-repudiation.
-
How should completed forms be stored and for how long
Store signed forms securely with access controls; retain tax-related records at least three years per IRC §6501(a), six years for HIPAA-covered records (45 CFR §164.530(j)), and longer where state or industry law requires.
