Day 29: Building a Compliance Checklist Using Notice CP 575
A Notice CP 575 is more than just an EIN confirmation letter—it is the foundation on which an LLC determines its correct federal tax filing obligations. By Day 29 of this course, you now understand how entity type, tax elections, and filing requirements connect. Today’s goal is to convert all that knowledge into a practical, repeatable Compliance Checklist that any LLC owner can use to stay aligned with the IRS and avoid penalties, mismatches, and incorrect form filing.
This checklist ensures that every year, your LLC reviews the right documents, confirms the correct tax election status, and files the required returns based on its CP 575 details.
Why a Compliance Checklist Matters
Many IRS penalties occur simply because business owners do not re-check their tax classification each year. If the CP 575 says one thing, but tax returns reflect another, the IRS issues mismatch notices, late penalties, and in some cases rejects entire filings.
A structured checklist protects the business by ensuring consistency between IRS records and filed tax forms.
Step 1: Verify EIN and Business Name from CP 575
Start your review by confirming:
• EIN on CP 575
• Legal name
• Responsible party
These must match all tax filings, bank accounts, payroll filings, and state registrations. Mismatches trigger IRS identity verification notices.
Step 2: Confirm Federal Tax Classification
The CP 575 notes the default classification based on the number of members in the LLC.
Verify whether:
• Single-member LLC → Default disregarded entity
• Multi-member LLC → Default partnership
• Any LLC → Elected C-Corp (Form 8832)
• Any LLC → Elected S-Corp (Form 2553)
Ensure elections match IRS acceptance letters. If no election letter exists, the default applies—never assume an S-Corp exists without written IRS confirmation.
Step 3: Check for Accepted IRS Elections
Your checklist must confirm:
• Do we have Form 2553 acceptance for S-Corp?
• Do we have Form 8832 acceptance for C-Corp?
• Are the effective dates correct?
• Have elections expired or been revoked?
If no acceptance letter exists, your LLC must not file as a corporation.
Step 4: Determine the Correct Annual Tax Form
Based on CP 575 and elections:
• Disregarded entity → Form 1040 Schedule C (unless foreign owner → Form 5472 + Pro-forma 1120)
• Partnership → Form 1065
• C Corporation → Form 1120
• S Corporation → Form 1120-S
This eliminates misfilings—one of the most common causes of penalties.
Step 5: Add State-Level Requirements
Even though CP 575 is federal, your checklist must include:
• Annual report due dates
• Franchise tax payments
• State employer tax accounts
• Registered agent renewal
Because states do not follow federal default classifications, this is vital for compliance.
Step 6: Payroll, Sales Tax & Other Accounts
Confirm:
• Payroll accounts match EIN
• Sales tax permits
• Worker classification (W-2 vs 1099)
• Quarterly payroll tax filings (941, 940)
• W-2s, 1099s filed on time
A mismatch in EIN or business name is the cause of rejected filings.
Step 7: Year-End Reconciliation
Before filing federal taxes:
• Match EIN on all documents
• Confirm tax form matches IRS classification
• Validate election status
• Review income and expense records
• Ensure member distributions match the tax type
This ensures the tax return reflects the business exactly as the IRS expects.
Step 8: Maintain a Compliance File
Your file should include:
• CP 575 Notice
• 2553 acceptance (if applicable)
• 8832 acceptance (if applicable)
• Past three years’ federal returns
• State registration & annual reports
• Operating agreement
Keeping all these documents allows yearly verification in minutes.
