DAY 30 – Final Project: Review a Sample CP 575 and Determine the Correct IRS Tax Form
Correct tax filing for LLCs begins with understanding what the IRS has already classified your company as — and Notice CP 575 is the only official document that tells you this. Throughout this 30-day course, you learned how to read EIN assignment rules, interpret IRS entity classifications, match them to tax forms, and avoid common tax-filing mismatches.
Today’s final project brings everything together with a practical, real-world scenario. Your task is simple but extremely important:
Review a sample Notice CP 575, identify the IRS default tax classification, and determine which IRS form the LLC must file.
This exercise reflects a real situation faced by accountants, bookkeepers, and U.S. business owners every tax season.

Sample Notice CP 575 Details (Hypothetical Example)
Below is a simplified version of the CP 575 information we will evaluate:
• Entity Name: Alpha Fintech LLC
• EIN: 12-3456789
• Type of Entity: Limited Liability Company
• IRS Default Tax Classification: Sole Proprietor
• Number of Members: 1
• Effective Date of EIN Assignment: January 10, 2024
• Filing Requirement Message: “You are required to file employment tax returns if you pay wages.”
• No Election Filed: No record of Form 8832 or 2553 received.
This is more than enough to determine the correct IRS tax form.

Step 1 — Identify the Default IRS Tax Classification
The CP 575 reveals:
• The entity is an LLC
• It has one member
• IRS assigned the default classification as “sole proprietor”
This means the IRS considers Alpha Fintech LLC a disregarded entity (unless an election is made).
──────────────────────────
Step 2 — Check Whether Any Tax Election Exists
The Notice states:
• “No record of Form 8832 or Form 2553 received.”
This tells us the LLC has NOT elected:
• C Corporation taxation (Form 8832), or
• S Corporation taxation (Form 2553)
Therefore, the IRS default classification remains valid.
──────────────────────────
Step 3 — Determine the Correct Tax Form
Based on the IRS rules:
• A Single-Member LLC (SMLLC) with no election
→ files taxes under the owner’s Form 1040, using Schedule C.
Therefore:
✔ Correct Tax Form: Form 1040 Schedule C
❌ Not Form 1065
❌ Not Form 1120
❌ Not Form 1120-S
──────────────────────────
Step 4 — Identify Any Additional Filing Requirements
Because the sample CP 575 states:
“You are required to file employment tax returns if you pay wages.”
This implies the LLC may also need:
• Form 941 – Quarterly payroll tax return
• Form 940 – Annual FUTA return
• State payroll filings
• W-2 & W-3 at year-end
If the business has no employees, these can be marked N/A.
──────────────────────────
Step 5 — Final Determination & Filing Summary
Final Classification:
✔ Single-Member LLC (Disregarded Entity)
Correct IRS Income Tax Form:
✔ Schedule C (Form 1040)
Additional Possible Filings (If applicable):
• Form 941
• Form 940
• State payroll reports
• W-2 / W-3
• 1099-NEC for contractors

By reviewing the key details in Notice CP 575, you successfully determined:
-
The IRS default tax classification
-
Whether any election changed that classification
-
The correct tax form for compliance
-
Additional filing obligations triggered by payroll activity
This concludes your 30-Day Course on Using Notice CP 575 for Correct LLC Tax Filing.
You now have the full skillset to:
• interpret CP 575
