EIN letter retrieval

Understanding and Retrieving Your EIN Confirmation: A Comprehensive Guide for US Business Owners and LLC Founders Your Employer Identification Number (EIN), also known as a Federal Tax Identification Number, is crucial for nearly all business activities, from opening a bank account to filing taxes and hiring employees.

But what happens if you lose your EIN confirmation letter? This guide provides comprehensive insights into retrieving your EIN and ensuring compliance.

CP 575 vs. Letter 147C: The Official Documents When the IRS first assigns your EIN, they issue a CP 575 notice, which is your original EIN confirmation letter.

This document contains your EIN, legal business name, address, and the date of issuance. It's important to note that the CP 575 is issued only once and cannot be reissued if lost.

If you need official proof of your EIN after the initial CP 575, you'll need to request an EIN Verification Letter, known as Letter 147C. This letter serves as an official substitute and is generally accepted by banks and government agencies as equivalent proof of your EIN.

How to Retrieve a Lost EIN or Obtain a Replacement (Letter 147C) 1. Check Internal Records First: Before contacting the IRS, search your business records.

Look for previously filed federal tax returns, payroll reports (Form 941), bank account documents, state registration records, or emails from your formation service. 2. Contact the IRS Business & Specialty Tax Line: If internal searches are unsuccessful, call the IRS directly at 1-800-829-4933 (domestic) or +1-267-941-1099 (international).

The line operates Monday to Friday, 7 a.m. to 7 p.m. local time. 3. Identity Verification: When you call, be prepared to verify your identity and authorization.

You'll need to provide the legal business name exactly as it appears on your EIN application, the business address on file, the responsible party's name and SSN/ITIN, and any other known application details. 4.

Requesting Letter 147C: You can request a 147C letter by phone or by mail. In urgent cases, the IRS may fax the 147C immediately, though mailed copies typically take 2-6 weeks to arrive. 5.

Authorized Parties: Only the EIN's responsible party or an authorized representative (such as an attorney or CPA with a Form 2848 Power of Attorney on file) can obtain official verification. If you need someone else to request verification on your behalf, ensure Form 2848 is properly submitted.

What Documents Do Banks and Partners Accept as Proof of EIN? Commonly accepted proofs include the original CP 575, a Letter 147C, an IRS-approved SS-4 form with the EIN notated (if provided at issuance), or recent federal tax returns displaying the EIN.

Always confirm specific documentation requirements with your bank or partner in advance, as policies can vary. State-Specific Considerations While the EIN is a federal identifier, many states require it for various registrations, especially if you plan to hire employees or collect sales tax.

The IRS recommends forming your legal entity with your state before applying for an EIN to streamline the process. California: The California Secretary of State registers and maintains records for corporations and LLCs.

State filings are separate from federal EIN issuance. New York: The New York Department of Taxation and Finance is a central hub for registering for corporation, sales, and withholding tax accounts.

Texas: The Texas Comptroller's office handles sales and franchise tax and business registration, often using the federal EIN for state tax registrations. It is advisable to check your specific state's Secretary of State and Department of Revenue/Comptroller pages for detailed requirements.

Compliance and Recordkeeping Best Practices Backup Your Documents: Keep multiple backups of your CP 575 or Letter 147C, including encrypted digital copies and printed copies in your corporate records binder.

Share copies with your bank and accountant. Update IRS Records: If your business information changes (e.g., responsible party, address), update IRS records using forms like Form 8822-B to avoid future verification issues.

Authorize a Tax Professional: Consider using Form 2848 to authorize a tax professional to handle EIN verification requests on your behalf, saving you time and effort. Timelines and Expectations Online EIN Application: Immediate.

Fax Application: Typically 4 business days for a faxed response. Mail Application: Approximately 4 weeks.

Replacement 147C: Phone requests may result in immediate fax in some cases; mail requests generally take longer (2-6 weeks).
