Introduction to Form 1120-S
When you own or manage an S corporation, understanding Form 1120-S is essential. This IRS form plays a key role in how S corporations report income and expenses.
In this article, we’ll explore what Form 1120-S is, who needs to file it, and why it matters for your business and taxes.
What is Form 1120-S?
Form 1120-S is the U.S. Income Tax Return for an S corporation. It reports the corporation’s income, deductions, gains, losses, and credits to the IRS.
Unlike a regular corporation, an S corporation itself generally does not pay income tax. Instead, income and losses pass through to shareholders.
Form 1120-S summarizes the financial activity of the S corporation.
It helps the IRS track income that flows to shareholders.
It includes schedules detailing income, deductions, and shareholder information.
Who Must File Form 1120-S?
Any corporation that has elected to be treated as an S corporation must file Form 1120-S annually.
The corporation must have filed Form 2553 to elect S status.
All domestic S corporations are required to file, even if they have no income.
Failure to file can result in penalties and loss of S corporation status.
