Closing a Business? Here's How to Stay on Top of Your Tax Duties

Sarah B

Businesses close for various reasons. Perhaps you’re ready to embark on a welcome change such as retirement or launching a new venture. Or maybe it just no longer makes financial sense to continue operating your current business. Whatever the reason, closing your business is a significant milestone, and part of wrapping things up means taking care of a few tax responsibilities.


Final Income Tax Returns

You’ll need to file a final income tax return and other required forms for your last year of operation. The specific forms you’ll file depend on your business structure:


Sole proprietorships: File Schedule C, Profit or Loss from Business, with your individual return for the year you close. You may also need to report self-employment tax.


Partnerships: File Form 1065, U.S. Return of Partnership Income, and report capital gains/losses on Schedule D. Mark the return and each Schedule K-1 as “final.”


All corporations: File Form 966, Corporate Dissolution or Liquidation, if you adopt a resolution to dissolve the corporation or liquidate stock.


C corporations: File Form 1120, U.S. Corporation Income Tax Return, for the closing year and report capital gains/losses on Schedule D. Check the “final return” box.


S corporations: File Form 1120-S, U.S. Income Tax Return for an S Corporation, for the year of closure and report gains/losses on Schedule D. Mark the return and each Schedule K-1 as “final.”


Regardless of business structure, additional forms may be required if you sell the business, report the sale of business property or record asset acquisitions.


Final Payments to All Workers

If you have employees, you must pay them whatever final wages and compensation are owed, make final federal tax deposits and report employment taxes. Don’t neglect to withhold all income, Social Security and Medicare taxes due and pay these taxes over to the IRS. Overlooking that requirement can result in full personal liability for what’s known as the Trust Fund Recovery Penalty. That’s an outcome to avoid.


Did you pay any independent contractors at least $600 during the calendar year you’re closing your business? If so, you must report those payments on Form 1099-NEC, “Nonemployee Compensation.”


More Loose Ends to Be Tied

If your business has an employee retirement plan, it’s essential to properly terminate it and distribute any remaining benefits. That process comes with its own checklist, including specific notice, funding and filing requirements. The same is true for employee benefit accounts such as Flexible Spending Accounts, Health Savings Accounts and other programs for your employees.


There are additional complex tax matters that may come into play, such as cancellation of debt, using up net operating losses, unlocking passive activity losses, depreciation recapture and even bankruptcy-related considerations. Addressing them can feel overwhelming, but you don’t have to do it alone. Contact the office for help.



Don’t forget about your business records. Depending on the type of records, there are specific rules for how long to retain them. When everything is squared away, you’ll also need to close your IRS business account. Note that while the Employer Identification Number itself is permanent, after receiving confirmation that the business has closed and verifying that there are no outstanding taxes or other issues, the IRS will make the account inactive.


What Else?

If your business is unable to pay all the taxes it owes, there are payment options available. To learn about these options, to ask about specific record retention rules or for any other issues, contact the office.

Employers seeking to offer family-friendly benefits may want to consider flexible spending accounts (FSAs) for dependent care. These FSAs let employees make pre-tax contributions through payroll withholding to help cover eligible expenses. Because of the major tax bill enacted on July 4, 2025, the annual contribution limit, currently $5,000, will rise to $7,500 in 2026. FSA contributions reduce employees’ income tax and payroll tax and employers’ payroll tax. Withdrawals used to pay qualified expenses are tax-free. These include expenses for care for a child under age 13 or another dependent unable to care for themselves due to physical or mental limitations. Contact the office with questions.
