Why a Clear, Compliant Tax IRS Letter Matters

Frequently Asked Questions About Tax IRS Letters
-
Can I e-sign an IRS response?
Yes. Electronic signatures are generally valid under the ESIGN Act (15 U.S.C. ch. 96) and UETA in most states, provided the signature demonstrates intent and records are retained.
-
When is notarization required?
Notarization is rarely required by the IRS for simple letters; however, certain affidavits or state-law documents attached may require notarization per state rules.
-
What if the TIN is wrong?
An incorrect TIN can trigger backup withholding or penalties; correct the record promptly and provide documentation to the IRS to avoid information return penalties under IRC §6721.
-
How should representatives sign?
An authorized representative should attach Form 2848 (Power of Attorney) and sign with their name, title, and date; include proof of authorization where required.
-
How long to retain copies?
Retain correspondence and supporting documents at least three years from filing per IRC §6501(a); retain longer if a significant understatement or industry rule applies.
-
What proof of submission is acceptable?
Keep certified mail receipts, tracking numbers, upload confirmation, or platform audit trails showing timestamps, signer identity, and document hashes for evidentiary use.
