How to Enter Your LLC Name on IRS Forms: Exact Match Rules (Form 1120 and 5472)

Exact Match Rule for LLC Names on IRS Forms

When entering your LLC name on Form 1120 and Form 5472, the IRS expects an exact match with the name on your EIN assignment notice (CP 575 or 147C letter). Every character — including spaces, punctuation, and the LLC designator — should match precisely.

Why Exact Matching Matters

The IRS uses computer systems to match filings with entity records. If the name on your tax return does not match the name associated with your EIN, your filing may be flagged for manual review, delayed, or rejected.

For foreign-owned LLCs, processing delays are especially problematic because they can trigger automatic penalty assessments.

How to Verify Your LLC Name

Check your CP 575 EIN confirmation letter or 147C verification letter. The name shown on these documents is the official name on file with the IRS. Use that exact name on all filings.

If you formed your LLC through a service like Stripe Atlas or doola, verify the name they registered matches what you intend to use on your tax filings.
