5-Step Legal Dissolution Roadmap
  1. Member Resolution: Formal written consent to dissolve approved by LLC owners.
  2. Settle Business Debts: Pay off all vendor invoices and tax liabilities.
  3. Close US Bank Accounts: Liquidate balances via final Owner's Draw wire.
  4. File State Articles of Dissolution: Submit Articles of Cancellation with Secretary of State.
  5. Final IRS Filing & EIN Closure: Mark "Final Return" on Form 5472 and mail EIN cancellation letter to IRS.

1. Why You Must Dissolve Legally (Risks of Abandonment)

Simply walking away from an active US LLC without formal dissolution is a dangerous mistake.

The state will continue to assess annual report fees and penalties. Furthermore, the IRS may continue issuing automatic $25,000 late penalties for unfiled Form 5472 tax returns until the entity is legally closed.

2. State Filings: Wyoming ($60) vs Delaware ($200)

Wyoming LLC Dissolution

File Articles of Dissolution with the Wyoming Secretary of State. State fee is $60. All annual reports must be current.

Delaware LLC Cancellation

File a Certificate of Cancellation with Delaware Division of Corporations. State fee is $200 + all paid franchise taxes ($300/yr).
