What happens if your EIN paperwork has errors?
Your Employer Identification Number (EIN) is your business's Social Security number. Errors on Form SS-4 or downstream filings don't always show up immediately — but when they do, they can freeze payroll and bank access.

Name mismatch is the most common problem
The name on your EIN must match your Secretary of State filing exactly, including punctuation, LLC vs Inc, and DBA notations.
Even 'ABC Company LLC' vs 'ABC Company, LLC' has caused IRS rejection notices.
Fix name errors with a written letter
The IRS does not offer an online correction form for EIN name errors. Mail a signed letter to the IRS office where you filed, explaining the discrepancy and requesting correction.
Include: EIN, original name filed, corrected name, business address, and copy of state formation document.
Responsible party changes require Form 8822-B
When the responsible party (or business address) changes, file Form 8822-B within 60 days.
Missing this triggers correspondence sent to old addresses — including IRS notices you cannot afford to miss.
Wrong entity classification blocks tax elections
An LLC that intended to elect S-corp status (Form 2553) but had SS-4 filed as sole proprietor can face rejected elections.
Fix by filing Form 8832 (Entity Classification Election) with a reasonable cause letter.
Payroll and banking break instantly
ADP, Gusto, QuickBooks Payroll, and business banks verify EINs through IRS TIN matching. Mismatches produce 'CP-2100' backup withholding notices at year-end.
Backup withholding requires you to withhold 24% from every 1099 payment until fixed — a massive cash flow hit.
Duplicate EINs are surprisingly common
Small business owners sometimes apply for a second EIN by accident during entity conversions. Only one should be used going forward.
Cancel the unused EIN by writing to the IRS with a formal cancellation letter — the EIN is never reissued, but it's marked inactive.
