Who Needs to File IRS Tax Form 1120-S: U.S. Income Tax Return for an S Corporation?

A corporation must file Form 1120-S if it elected to be an S corporation by filing Form 2553, and the Internal Revenue Service (IRS) accepted the election. The IRS uses the ownership percentage detailed in Form 1120-S to allocate how much profit and loss should be assigned to an individual shareholder.

If the shareholder does not see a change in this percentage during the year, profit and loss are relatively easy to calculate. However, if the individual purchases additional shares, or sells or transfers any holdings during the course of the year, then profit and loss must be pro-rated on a per-share basis.

Form 1120-S is filed by S corporations. This business structure allows a corporation to pass corporate income, losses, deductions, and credits through to shareholders for federal tax purposes.

Special Considerations When Filing Form 1120-S

Why File Form 1120-S

Corporations with fewer than 100 shareholders may choose to form an S corporation for the purposes of avoiding double federal taxation. That is, the corporation passes its income along to the shareholders for the purposes of taxation. The shareholders are taxed but not the corporation.

In addition, if the corporation does not have significant inventory, it is able to use the cash method of accounting under S corporation terms. This can be far simpler than the accrual method.

While S corporations have significant advantages, some downsides include being subject to many of the same rules that corporations (C corporations) must follow, including high legal and tax service fees.

How C and S Corporations Are Similar

Both S corporations and C corporations must also file articles of incorporation and hold regular meetings for directors and shareholders with detailed minutes. These meetings must be forums that allow shareholders to vote on major corporate decisions such as management restructuring, mergers and acquisitions, and new investments.

Finally, S corporations and C corporations have similar legal and accounting costs of set-up.

While C corporations may issue several classes of stock, S corporations can only issue one class. It can be argued that this hampers a company's ability to raise capital.
