What is the difference between Form 8821 and Form 2848 for a business?\u003c\/strong\u003e Form 8821 authorizes a tax professional to inspect and receive confidential tax information only. It does not grant power of attorney. Form 2848 grants representation rights, meaning the professional can speak to the IRS on the client's behalf. If you only need transcript access and account information for a business client, Form 8821 is the correct form.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003e2. What name do I use in Line 1 if my client operates under a DBA?\u003c\/strong\u003e Use the legal entity name exactly as it appears in IRS records. That is the name tied to the EIN. A DBA, trade name, or shortened version will cause a name mismatch rejection. Use the CP 575 or 147-C letter to confirm the correct name before completing the form.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003e3. Which tax form numbers do I list in Line 3 for a business?\u003c\/strong\u003e For income taxes, list 1120, 1120S, 1065, or 1041 depending on the entity type. For payroll taxes, list 940, 941, 943, and 944. For civil penalties and Section 4980H, list N\/A. This guide includes the exact combinations for common business structures.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003e4. What title does the signer need to put on Line 6?\u003c\/strong\u003e The title must match the entity type. For a corporation, accepted titles include President, Vice President, Secretary, Treasurer, CEO, CFO, or Director. For an LLC, use Member or Manager. For a partnership, use Partner. A missing or mismatched title is one of the most common rejection reasons and it is entirely avoidable.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003e5. Can my client use an e-signature on Form 8821?\u003c\/strong\u003e No. The IRS does not accept e-signatures on Form 8821. A wet-signed original is required. The signature date also cannot be more than 120 days old at the time of submission. This guide covers the signature requirements so you collect the right thing from clients the first time.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003e6. What do I do if the form is rejected because the business name does not match?\u003c\/strong\u003e Verify the correct legal name using the CP 575 EIN confirmation letter or by requesting a 147-C letter from the IRS Business and Specialty Tax Line at 800-829-4933. Then resubmit with the corrected name. The guide explains this process and how to prevent it before submission.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003e7.
