Businesses shut down for many reasons. Examples include an owner’s retirement, a lease expiration, staffing shortages, partner conflicts, and increased supply costs. If you’ve decided to close your business, you might need assistance with some steps, including handling various tax obligations.

Tax Return and Forms

A final income tax return and related forms must be filed for the year of closing. The correct return to file depends on the type of business.

Here’s a rundown of the requirements.

Sole proprietorships. You must file the usual Schedule C, “Profit or Loss from Business,” with your individual return for the year of closing. You may also need to report self-employment tax.

Partnerships. A partnership must file Form 1065, “U.S. Return of Partnership Income,” for the year of closing and report capital gains and losses on Schedule D. Indicate that this is the final return and do the same on Schedules K-1, “Partner’s Share of Income, Deductions, Credits, etc.”

All corporations. Form 966, “Corporate Dissolution or Liquidation,” must be filed if you adopt a resolution or plan to dissolve a corporation or liquidate its stock.

C corporations. File Form 1120, “U.S. Corporate Income Tax Return,” for the year of closing. Report capital gains and losses on Schedule D. Indicate this is the final return.

S corporations. File Form 1120-S, “U.S. Income Tax Return for an S Corporation,” for the year of closing. Report capital gains and losses on Schedule D. The “final return” box must be checked on Schedule K-1.

All businesses. If you sell your business, other forms may need to be filed to report the sales.
