30-Day Course: Using Notice CP 575 to Determine Correct Tax Filing for LLCs
Step-by-Step Guide: From CP 575 to Tax Form Selection

Choosing the correct U.S. federal tax form for an LLC starts with one key document: the Notice CP 575. This IRS-issued confirmation letter contains the information needed to determine how the LLC is classified for tax purposes by default and what filing requirements apply. Day 22 provides a clear, step-by-step method to interpret the CP 575 and convert it into the correct filing pathway for your LLC or your client’s business.

Understanding the Importance of CP 575

Notice CP 575 confirms the EIN and the entity type selected (or defaulted) at the time of application. Many LLC owners assume their tax filing obligations based on hearsay or general advice, but the CP 575 serves as the authoritative source. It clarifies what the IRS expects and prevents incorrect filings that could result in penalties, rejections, or unnecessary back-and-forth with the IRS.

Step 1: Locate the Entity Type Section

On CP 575, the IRS displays the “Entity Type.” This may include phrases such as Limited Liability Company, Corporation, Partnership, Sole Proprietor, or others. For LLCs, this line might not directly state “single-member” or “multi-member,” so you must evaluate the owner count separately.

If the CP 575 says LLC but does not specify corporation, then the default classification rules apply:

• 1 owner = Disregarded entity

• 2 or more owners = Partnership

Step 2: Match Entity Type with Default IRS Classification

If the LLC has:

• One owner – The default filing is Schedule C on Form 1040.

• Multiple owners – The default filing is Form 1065 for partnerships.

If the CP 575 indicates the business is a corporation, then the LLC is no longer under default classification. This means the owner previously filed Form 8832 or Form 2553.

Step 3: Check for IRS Elections

The CP 575 sometimes references elections on file. If an election was made, the tax forms change accordingly:

• C Corporation Election – File Form 1120

• S Corporation Election – File Form 1120-S

If you are unsure whether an election has been made, review the acknowledgment letters:

• Form 8832 Acceptance Letter

• Form 2553 Acceptance Letter (S Corp approval)

Step 4: Verify the Effective Date of Any Elections

An election does not always take effect on January 1. Make sure the election’s effective date aligns with the tax year you’re preparing. Filing the wrong form for a year before the election becomes active is one of the most common mistakes business owners make.

Step 5: Translate CP 575 Details Into the Correct Tax Form

Using CP 575 information, choose the appropriate filing form:

• LLC with no election, 1 owner – File Form 1040 Schedule C

• LLC with no election, 2+ owners – File Form 1065

• LLC with C Corp election – File Form 1120

• LLC with S Corp election – File Form 1120-S

Step 6: Confirm if Any Additional Filings Are Required

Certain classifications require additional annual filings.

• Form 1065 requires issuing Schedule K-1

• Form 1120-S requires payroll compliance for reasonable compensation

• Disregarded entities with employees must file separate payroll returns

Step 7: Document and Maintain CP 575 for Future Years

Always attach a copy of CP 575 to your permanent client records. If the IRS questions your filing method, CP 575 serves as proof of the entity type.

Practical Example

A single-member LLC whose CP 575 states LLC without any election:

Tax form = Form 1040 Schedule C

A multi-member LLC with CP 575 stating LLC and Form 8832 acceptance letter received later:

Tax form = Form 1120 (C Corporation)

A single-member LLC with CP 575 stating LLC, but also has Form 2553 approval:

Tax form = Form 1120-S

Summary

CP 575 is more than an EIN confirmation; it’s a roadmap for accurate tax filing. By reading the entity type, checking for elections, and aligning the details with IRS classification rules, you ensure correct and compliant filing for any LLC structure.
