Day 4: Understanding “Entity Type” as Shown on Notice CP 575
When you receive Notice CP 575 from the IRS, one of the most important elements on the letter is the “Entity Type” assigned to your business. This designation plays a direct role in determining how your LLC will be treated for federal tax purposes and which tax return you must file. Day 4 of our 30-Day CP 575 course focuses on breaking down what “Entity Type” means, why it appears on your EIN confirmation letter, and how to interpret it correctly to avoid misfiling your business taxes.
Many new LLC owners assume that forming an LLC automatically tells the IRS how the entity should be taxed. However, the IRS does not recognize the LLC structure as a tax classification by itself. This means your initial entity type on Notice CP 575 is usually a default classification based on whether your LLC is single-member or multi-member, unless you choose otherwise by submitting Form 8832 or Form 2553. Understanding this helps ensure your business files the correct federal tax return.
Your Notice CP 575 may list the entity type as “Sole Proprietor,” “Partnership,” “Corporation,” or “Other.” These designations reflect how the IRS expects your business to be taxed on day one. For example, a single-member LLC often receives the default classification of “Sole Proprietor,” which corresponds to filing taxes on Schedule C. A multi-member LLC typically defaults to “Partnership,” which would require filing Form 1065. This default matters because filing the wrong return can lead to penalties, processing delays, or IRS notices.
It is also possible to see the entity type listed as “Corporation” if you selected corporate classification on Form SS-4 or previously submitted Form 8832. If you chose S corporation status using Form 2553, the CP 575 may not always reflect the S corp election immediately because that election is processed separately. This is why matching the CP 575 information with your election filings is essential before preparing your return.
Because the CP 575 represents the IRS’s record of your business structure at the time the EIN was issued, reviewing the “Entity Type” line helps ensure your tax filings stay aligned with IRS expectations. If your business has changed its classification since receiving the notice, it’s important to maintain documentation and validate that your elections were accepted.
By understanding the “Entity Type” on Notice CP 575, LLC owners can avoid incorrect filings and maintain compliance from the beginning. It’s a simple step that protects your business from avoidable complications. Tomorrow, in Day 5, we’ll break down how CP 575 connects directly to your required annual tax forms.
