Form 1120-S: U.S. Income Tax Return for an S Corporation is the tax document utilized by S corporations to report income, gains, losses, credits, deductions, and other crucial information to the Internal Revenue Service (IRS). Effectively, Form 1120-S serves as the annual tax return for S corporations, and must be filed by the 15th day of the 3rd month after the corporation’s tax year ends.
Key Takeaways

Who Needs to File IRS Tax Form 1120-S?
A corporation must file Form 1120-S if it has elected to be treated as an S corporation by submitting Form 2553: Election by a Small Business Corporation, and the IRS has approved this election. S corporations, designed for smaller enterprises with fewer than 100 shareholders, pass their tax liabilities directly to individual shareholders instead of paying corporate taxes, thus avoiding double taxation.
Details to Include
The IRS uses ownership details provided in Form 1120-S to determine individual shareholders’ proportional profits and losses.
- Calculations are straightforward if no changes in share percentages happen during the year.
- Adjustments must be made for any purchase, sale, or transfer of shares, with profits and losses prorated accordingly.
S corporations pass through corporate income, losses, deductions, and credits to shareholders, which are then reported on their individual tax returns.
