Fillable Form 1120-S: US Income Tax Return for an S Corporation

What is Form 1120-S?

Form 1120-S, US Income Tax Return for an S Corporation, is an Internal Revenue Service (IRS) form used to report the income, gains, losses, deductions, credits, and other relevant financial information of a domestic corporation or an S corporation. In effect, IRS Form 1120-S is the tax return of an S Corporation.

S Corporations are a type of corporation that meet specific Internal Revenue Code requirements, allowing them to pass income (along with other credits, deductions, and losses) directly to shareholders, without having to pay federal corporate taxes.

The IRS uses the ownership percentage detailed in the 1120-S IRS form to allocate how much profit and loss should be assigned to an individual shareholder.

Who needs to use Form 1120-S?

A corporation must file Form 1120-S IRS if it elected to be an S corporation by filing Form 2553, and the Internal Revenue Service (IRS) accepted the election.
