To close a single-member LLC with the IRS, you file a final Schedule C with your personal Form 1040, file final employment and excise tax returns if they apply, take care of any asset sales or debt cancellations on the way out, terminate any retirement plan you set up through the business, and then mail the IRS a letter asking it to deactivate your Employer Identification Number.1Internal Revenue Service. Single Member Limited Liability Companies Because the IRS treats most single-member LLCs as disregarded entities, there’s no separate business return to close out — the business income has always flowed through your 1040, and the final year works the same way.
Wind Down Operations and Dissolve at the State Level First
You can’t accurately prepare final tax forms while money is still moving through the business. Finish or cancel service agreements, collect what’s owed to you, pay what you owe, and either sell remaining inventory or move it to personal use.
Then dissolve or cancel the LLC at the state level through your Secretary of State or equivalent office. State dissolution and federal tax closure are separate — completing one doesn’t accomplish the other. Some states will keep charging annual fees or franchise taxes until you file dissolution paperwork, so don’t leave that step for later.
File the Final Schedule C
Your final business reporting happens on Schedule C attached to your Form 1040, exactly the way you’ve always done it. The only difference: you report only income earned and expenses incurred through the date you stopped operating.2Internal Revenue Service. Limited Liability Company – Possible Repercussions The IRS has no way to know you closed unless the final return tells them.
If the final Schedule C shows a net profit, self-employment tax applies to that profit on Schedule SE, calculated the same way as any other year.1Internal Revenue Service. Single Member Limited Liability Companies The return is due by the normal individual filing deadline, April 15 of the year after you closed.3Internal Revenue Service. When to File
Final Employment Tax Returns If You Had Employees
If your LLC ever ran payroll, employment tax closure is its own set of filings, and each form needs the “final return” checkbox marked.
File a final Form 941 (or Form 944, if that’s what you file annually) covering payroll through your last check.4Internal Revenue Service. Instructions for Form 941 File a final Form 940 for federal unemployment tax for the year of closure. Every employee who received wages during the calendar year gets a Form W-2, due by the same deadline as your final 941 or 944, with Copy A sent to the Social Security Administration on Form W-3.5Internal Revenue Service. Closing a Business
Any independent contractor you paid $600 or more during the year needs a Form 1099-NEC. Paper filers send them to the IRS with Form 1096 as the transmittal.5Internal Revenue Service. Closing a Business If you filed Form 720 for excise taxes, file a final Form 720 and check the “Final” box above Part I.
If Your LLC Elected Corporate Tax Treatment
A small share of single-member LLCs file Form 8832 to be taxed as a corporation instead of as a disregarded entity.6Internal Revenue Service. About Form 8832 – Entity Classification Election If that’s you, closure is more involved.
- S corporation election: file a final Form 1120-S for the year of closure, marked as the final return.
- C corporation election: file a final Form 1120 for the year of closure, marked as the final return.
Either way, you also file Form 966, Corporate Dissolution or Liquidation, within 30 days after adopting your plan to dissolve or liquidate.7eCFR. 26 CFR 1.6043-1 – Return Regarding Corporate Dissolution or Liquidation That 30-day window is easy to miss, because the clock starts when you decide to close, not when you finish winding down.
Handle Assets, Debts, and Retirement Plans on the Way Out
Most single-member LLCs have some property left at the end. How that property leaves the business decides whether more tax is owed.
Selling Business Assets
Report the gain or loss from selling business property on Form 4797.8Internal Revenue Service. About Form 4797, Sales of Business Property Gain is the difference between what you received and the asset’s adjusted basis (original cost minus depreciation taken). For tangible personal property like machinery, equipment, or furniture (Section 1245 property), any gain up to the depreciation you previously claimed is taxed as ordinary income rather than at capital gains rates.9Office of the Law Revision Counsel. 26 USC 1245 – Gain From Dispositions of Certain Depreciable Property If you took large Section 179 write-offs when you bought the equipment, the recapture hit can be sizable.
Keeping Assets for Personal Use
Taking a business asset home isn’t a taxable event on its own. The LLC is disregarded, so you’re moving property from one pocket to another. Carry the adjusted business basis with the asset — if you later sell that laptop or truck, the gain is measured from that basis, not from what it was worth on the day you closed.
Cancelled Debt
If a creditor forgives part of a business debt during wind-down, the forgiven amount is generally taxable income on your final Schedule C. Creditors who cancel $600 or more must send Form 1099-C.10Internal Revenue Service. About Form 1099-C, Cancellation of Debt If the business was insolvent immediately before the cancellation (liabilities exceeded assets), you can exclude the cancelled amount from income, but only up to the amount by which you were insolvent.11Office of the Law Revision Counsel. 26 USC 108 – Income From Discharge of Indebtedness The exclusion is claimed on Form 982.
Retirement Plans
A SEP-IRA can be terminated at any time with no IRS filing. Stop contributions, tell any employees, and notify the financial institution holding the accounts. Money already in each SEP-IRA stays put.12Internal Revenue Service. Retirement Plans FAQs Regarding SEPs
A Solo 401(k) requires a final Form 5500-EZ for the plan’s last year even if plan assets are under $250,000. The under-$250,000 exemption doesn’t apply in the final plan year.13Internal Revenue Service. Instructions for Form 5500-EZ Plan assets must be distributed as soon as administratively feasible after termination; a rollover to an IRA or another eligible plan avoids immediate taxation.
Send the Letter to Deactivate Your EIN
The IRS doesn’t actually cancel EINs. Once assigned, an EIN is permanently tied to that entity and is never reused. What the IRS does is deactivate the account so it no longer has active filing obligations.14Internal Revenue Service. If You No Longer Need Your EIN
Mail your request to:
Internal Revenue Service
Cincinnati, OH 45999
Include:
- The LLC’s full legal name exactly as it appeared on the EIN application.
- The nine-digit EIN.
- The business mailing address.
- The reason for closing (a simple statement that the business has ceased operations).
- A copy of the EIN assignment notice (CP 575 or 147C), if you still have it.
The IRS will only process the deactivation after all required final returns are filed. Send the letter before your final Schedule C or employment tax forms clear, and the request will sit until they do.
Keep Records After You Close
Don’t shred everything the day after you mail your final return. Income tax records need to be kept at least three years from the date the final return was filed. Employment tax records carry a longer requirement of at least four years from the date the tax was due or paid, whichever is later.15Internal Revenue Service. How Long Should I Keep Records The simplest approach is to hold everything for four years and not worry about sorting the piles.
What Happens If You Skip These Steps
Failing to file doesn’t erase the obligation, it creates new ones. The IRS charges a failure-to-file penalty of 5% of the unpaid tax for each month the return is late, up to a maximum of 25%. If the return is more than 60 days late, the minimum penalty is $525 or 100% of the unpaid tax, whichever is less.16Internal Revenue Service. Failure to File Penalty Interest runs on top of the penalty from the original due date.
If the LLC elected S corporation treatment, the penalty is $255 per month per shareholder for up to 12 months. For a single-member LLC taxed as an S corp, that runs up to $3,060 for a late return even with no tax owed.16Internal Revenue Service. Failure to File Penalty
Beyond penalties, leaving the EIN active means the IRS may keep expecting returns. Owners who never formally close sometimes receive CP-259 or CP-518 notices years later asking why no return was filed. Cleaning up an account after the fact takes far more time than doing it right the first time.
