Closing a business is a tax event, not just a business decision. The IRS, your state, and various agencies need to be formally notified, and specific tax returns must be filed (marked as “Final” returns). Assets must be properly disposed of, and the tax consequences of selling, donating, or scrapping business assets depend on how they were depreciated. An S-Corp that previously elected S-Corp status must file a final Form 1120S. Payroll obligations must be formally closed (final Form 941, final W-2s, final FUTA return). State obligations vary but typically include filing articles of dissolution, final state tax returns, and final sales tax returns. Missing any of these steps can create phantom tax obligations, late-filing penalties, and ongoing state annual report fees on a business that no longer operates.

✓Key takeaway

Business closure checklist (IRS and federal):

File final federal tax return:
- Sole proprietor: final Schedule C with Form 1040 (check “Final return” box)
- S-Corp: final Form 1120S (check “Final return” box on page 1)
- Partnership: final Form 1065 (check “Final return” box)
- C-Corp: final Form 1120 (check “Final return” box)
- File by the normal due date for the final tax year
Dispose of assets:
- Selling assets: recognize gain or loss on each asset
- Equipment: depreciation recapture under IRC 1245 (ordinary income up to depreciation taken)
- Real property: IRC 1250 recapture (25% max on depreciation taken)
- Goodwill/customer list: capital gain if sold
- Scrapping/abandoning: ordinary loss (deduct remaining basis)
- Donating: deduct fair market value (subject to charitable deduction limits)
Cancel EIN:
- Write to IRS at: Internal Revenue Service, Cincinnati, OH 45999
- Include: legal name, EIN, business address, reason for closing
- The EIN is never reused (even after cancellation)
- Note: you can’t cancel an EIN online or by phone
Final payroll obligations (if employees):
- Final Form 941 (quarterly payroll return): check “Final return” box
- Final W-2 for all employees: due by January 31 after the final year
- Final Form 940 (FUTA): check “Final return” box
- Pay all remaining payroll taxes owed
- File state payroll final returns
1099 reporting:
- File all required 1099s for the final year
- 1099-NEC for subcontractors paid $600+ during the final year
- Due January 31 after the final year (even if the business closed mid-year)
Cancel licenses and permits:
- Business license (city/county)
- Professional license (if applicable)
- Sales tax permit (see state obligations below)

State obligations:

File articles of dissolution with the Secretary of State
Final state income tax return (marked “Final”)
Final sales tax return (if applicable): remit all collected tax
Cancel state employer registration
Cancel business license
If you DON’T file dissolution: annual report fees and penalties continue indefinitely

Common closure mistakes:

Mistake	Consequence
Not marking returns as “Final”	IRS expects future returns; non-filing penalties
Not dissolving with the state	Annual report fees continue ($50-$500/year)
Not filing final 941	Payroll tax penalties and interest
Not canceling sales tax permit	State expects continued returns
Not filing final 1099s	Penalties of $60-$310 per missing form
Keeping the bank account open	Potential constructive receipt of income

What happens to business assets when you close?

Hypothetical example

Round numbers. A plumbing business closing after 8 years. S-Corp. Single filer.

Assets at closure:

Asset	Original Cost	Depreciation Taken	Remaining Basis	Sold For
Van	$40,000	$40,000 (fully depreciated)	$0	$8,000
Tools and equipment	$25,000	$25,000 (fully depreciated)	$0	$3,000
Sewer camera	$10,000	$10,000	$0	$2,000
Office furniture	$3,000	$3,000	$0	$200
Customer list (self-created)	$0	$0	$0	$15,000
Phone number/brand	$0	$0	$0	$5,000
Total				$33,200

Tax on asset sales:

Van ($8,000 gain, fully depreciated): IRC 1245 recapture = $8,000 ordinary income
Tools ($3,000 gain): IRC 1245 recapture = $3,000 ordinary income
Sewer camera ($2,000 gain): IRC 1245 recapture = $2,000 ordinary income
Office furniture ($200 gain): IRC 1245 recapture = $200 ordinary income
Customer list ($15,000): capital gain (self-created goodwill, long-term)
Phone/brand ($5,000): capital gain

Tax calculation: Ordinary income (recapture): $13,200 x 22% = $2,904 Capital gain: $20,000 x 15% = $3,000 Total tax on asset disposition: $5,904

If instead you just scrap/abandon everything (keep customer list for yourself):

Van, tools, camera, furniture: $0 proceeds. No gain. No recapture. No tax.
Customer list stays with you (no sale, no gain)
Tax on disposition: $0

The choice to sell or scrap assets directly affects the closure tax bill. Selling generates income (and recapture tax). Scrapping avoids recapture but surrenders the cash.

Remaining S-Corp obligations:

Final Form 1120S: due March 15 of the year after closure (or September 15 with extension)
Final K-1 to the owner
Distribute all remaining cash from the S-Corp bank account to the shareholder
Excess distributions beyond stock basis: capital gain
Close the S-Corp bank account AFTER all final checks have cleared

S-Corp dissolution with remaining cash: If the S-Corp bank account has $30,000 after all expenses and asset sales:

Owner’s stock basis: $20,000 (accumulated from original investment and retained earnings)
Distribution: $30,000
Excess: $30,000 - $20,000 = $10,000 capital gain
Tax: $10,000 x 15% = $1,500

If stock basis was $35,000: the full $30,000 distribution is tax-free (return of capital), and the owner has a $5,000 capital loss.

Timeline for closing (typical):

Step	Timing
Decision to close	Day 1
Notify employees	Within required state notice period
Final payroll	Last day of operations
Sell/dispose of assets	Within 30-60 days
File articles of dissolution	Within 30 days of final operations
Final Form 941	Next quarterly due date
Cancel sales tax permit	Within 30 days
Final W-2s	By January 31
Final 1099s	By January 31
Final Form 1120S (or Schedule C)	By March 15 (S-Corp) or April 15 (sole prop)
Cancel EIN (letter to IRS)	After final return filed
Close bank account	After all checks clear and final return filed
