IRS Publication 5447 – How to Close a Sole Proprietorship

IRS Publication 5447 – Closing a sole proprietorship is simpler than dissolving a corporation or partnership, but it still requires careful handling of federal tax obligations to avoid penalties, audits, or issues with the IRS. Whether you’re retiring, pivoting to a new venture, or shutting down due to changing circumstances, following official IRS guidance ensures compliance.

IRS Publication 5447, titled “How to Close a Sole Proprietorship” (revised September 2020, Catalog Number 74904N), serves as the authoritative one-page checklist from the IRS. As of February 2026, this remains the current official publication referenced on the IRS “Closing a Business” page (last reviewed August 18, 2025). You can download the free PDF directly here: https://www.irs.gov/pub/irs-pdf/p5447.pdf (Spanish version also available).

This guide expands on Publication 5447 with clear explanations, required forms, timelines, and additional trusted IRS resources to help you close your business correctly.

What Is a Sole Proprietorship and When Should You Close It?

A sole proprietorship is an unincorporated business owned and operated by one individual. For federal tax purposes, the business income and expenses flow directly to your personal Form 1040 via Schedule C. No separate business tax return is filed, and there are no formal “dissolution” documents to file with the IRS or your state for the federal side.

You may decide to close when:

  • Operations cease permanently
  • You sell the business assets
  • You convert to another structure (e.g., LLC)
  • Retirement, relocation, or economic reasons apply

Important: Even if you operated for only a few months, you must file a final return for the year you close. Always check your state requirements separately (e.g., canceling business licenses, DBA filings, or state tax accounts), as the IRS does not handle these.

Step-by-Step Process to Close a Sole Proprietorship (Per IRS Publication 5447)

Follow these steps in order. Publication 5447 organizes them as a clear checklist.

1. File Your Final Income Tax Return

Report all business activity up to the date you close.

  • File Schedule C (Form 1040 or 1040-SR) — Profit or Loss from Business with your personal Form 1040 (or 1040-SR for seniors).
  • Mark the return clearly as your final return if prompted by tax software or on paper.
  • If you sold or exchanged business property (e.g., equipment, vehicles): File Form 4797 — Sales of Business Property.
  • If you sold the entire business: File Form 8594 — Asset Acquisition Statement.
  • If subject to self-employment tax (net earnings ≥ $400): File Schedule SE (Form 1040).

Deadline: Same as your personal tax return (typically April 15 of the following year, or October 15 with extension). Report income received and expenses incurred before closure.

Pro Tip: Use IRS Free File, tax software, or a CPA. Indicate in the software that you “disposed of” or “closed” the business.

2. Deposit and File Employment Taxes (If You Had Employees)

If your sole proprietorship ever had employees, handle these before closing:

  • Make final federal tax deposits for withheld income, Social Security, Medicare, and FUTA taxes.
  • File Form 941 (quarterly) or Form 944 (annual) for the quarter/year of final wages. Check the “final return” box and enter the date of final wages.
  • File Form 940 — Employer’s Annual Federal Unemployment (FUTA) Tax Return for the year of final wages. Check box “d” for final return.
  • Issue Form W-2 to each employee by the due date of the final Form 941/944.
  • File Form W-3 to transmit Copy A of W-2s to the Social Security Administration.
  • If employees received tips: File final Form 8027.
  • If you offered pension or benefit plans: File Form 5500.

Failure to deposit or withhold can trigger the Trust Fund Recovery Penalty.

3. Report Payments to Contract Workers (Independent Contractors)

If you paid any contractor $600 or more in the year of closure for services (including parts and materials):

  • Issue Form 1099-NEC — Nonemployee Compensation to each contractor.
  • File Form 1096 to transmit paper copies to the IRS (electronic filing required for many businesses).
  • Deadline: January 31 of the following year for recipients; February 28/March 31 for IRS (electronic).

This is a common oversight highlighted in Publication 5447.

4. Close Your IRS Business Account and Cancel Your EIN

You must file all tax returns and pay any owed taxes before the IRS will close your account.

  • Write a signed letter including:
    • Complete legal name of the business
    • Employer Identification Number (EIN)
    • Business address
    • Reason for closing the account
  • Attach a copy of the original EIN assignment notice (CP 575) if you have it.
  • Mail to:
    Internal Revenue Service
    Cincinnati, Ohio 45999

Note: You cannot close the EIN online or by phone. Do this last, after all returns are filed and processed. Single-member LLCs taxed as disregarded entities follow the same process.

5. Pay Any Taxes Owed and Take Final Steps for Employees/Contractors

  • Use IRS Direct Pay, EFTPS, or other options at IRS.gov/payments.
  • If you had employees or contractors, ensure all final wages, 1099s, and W-2s are handled.

Additional Important Steps Beyond Publication 5447

The IRS “Closing a Business” page (irs.gov/closingabiz) recommends these:

  • Keep Records: Retain business records for at least 3 years (up to 7 for some items). Keep property records until the statute of limitations expires for the year you disposed of the asset. Employment tax records: at least 4 years.
  • State and Local Obligations: Cancel state tax accounts, business licenses, permits, and fictitious name registrations. Check your state’s Secretary of State or Department of Revenue website.
  • If You Sold the Business: Report the sale on your final Schedule C and related forms. Buyers may need Form 8594 too.
  • Bank Accounts and Insurance: Close business bank accounts and cancel insurance policies.
  • Notify Vendors/Clients: Send final communications and settle accounts.

Common Mistakes to Avoid When Closing a Sole Proprietorship

  • Forgetting to mark returns as “final”
  • Missing 1099-NEC deadlines
  • Not canceling the EIN (leads to future IRS correspondence)
  • Ignoring state requirements
  • Disposing of assets without filing Form 4797 (recapture of depreciation or Section 179)

Frequently Asked Questions (FAQ)

Do I need to file anything special with the IRS just to close?
No formal dissolution form is required for sole proprietorships — just the final Schedule C and the EIN closure letter.

What if I had no employees and no contractors?
Your process is simplest: File final Schedule C (and any asset-sale forms), then send the EIN closure letter after filing.

Can I reopen later?
Yes — a new EIN is not needed if you use the same one, but notify the IRS if reactivating.

Is Publication 5447 still current in 2026?
Yes. The IRS continues to link it directly on its official closing-a-business page with no revisions issued since September 2020.

Should I hire a tax professional?
Highly recommended if you had employees, sold assets, or have complex finances. A CPA or enrolled agent can ensure everything is filed correctly.
