For S corporations, the reporting of certain taxable activity is \u201cpassed through\u201d to the company\u2019s shareholders. But that doesn\u2019t mean the Internal Revenue Service doesn\u2019t need a record of it. So, where is all that information captured?&nbsp; The answer is Form 1120-S.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"IRS Form 1120-S: Filing Guide for S Corporations | Block Advisors\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/vxJR7Gjn_2Q?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-is-irs-form-1120-s\">What is IRS Form 1120-S?<\/h2>\n\n\n\n<p>IRS Form 1120-S is the tax form S corporations use to file a federal income tax return. This tax form informs the IRS of your total taxable earnings in a tax year. It\u2019s used to determine an S corporation\u2019s business income, gains, losses, tax credits, and deductions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-who-should-fill-out-the-1120-s-tax-form\">Who should fill out the 1120-S Tax Form?<\/h2>\n\n\n\n<p>Every S corporation should file the 1120-S tax form, including LLCs taxed as S corporations. Employees or shareholders of an S corporation don\u2019t need to file this form. Earnings should be reported on their individual tax return. Employees will receive a W-2 form from the corporation, while shareholders will receive a Schedule K-1 (Form 1120-S).<\/p>\n\n\n\n<p>If you want to elect S corporation status, you should file <a href=\"https:\/\/www.blockadvisors.com\/resource-center\/small-business-tax-prep\/form-2553\/\">Form 2553<\/a> to transition your business to an S corporation either during the corporation\u2019s first tax year for which you want to make the election or within the first 2.5 months following that first tax year. Once you elect treatment as an S corporation, you should file the 1120-S tax form each year for federal tax purposes.<\/p>\n\n\n\n<p><em>Important reminder: This tax form closely resembles <a href=\"https:\/\/www.blockadvisors.com\/resource-center\/small-business-tax-prep\/form-1120\/\">IRS Form 1120<\/a>, typically filed by C Corporations. However, S Corporations should always file IRS Form 1120-S. Need a quick refresher on other business types?

The first is Schedule B.

This section helps you reconcile income or <a href=\"https:\/\/www.blockadvisors.com\/resource-center\/small-business-tax-prep\/claiming-business-loss-deduction\/\">loss<\/a> per book with your return.<\/p>\n\n\n\n<p>If you fill out Schedule L, you should also complete Schedule M-1.

So, if your business\u2019 tax year ends on December 31, your 1120-S due date is March 15 each year. \u00a0(Unless it falls on a weekend or holiday. Then it\u2019s usually the next business day.)<\/p>\n\n\n\n<p>When you need more time to get your return together, you can file for a corporate tax return extension using IRS Form 7004. The S Corp extension due date is September 15, and you can e-file <a href=\"https:\/\/www.blockadvisors.com\/resource-center\/small-business-tax-prep\/form-7004\/\">IRS Form 7004<\/a>. (The same goes for the deadline here\u2014if it falls on a weekend or holiday, the due date is the next business day.)<\/p>\n\n\n\n<p>If your company dissolves, you should file on the 15th day of the third month after shutting down.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-more-expert-guidance-on-small-business-taxes\">More expert guidance on small business taxes<\/h2>\n\n\n\n<p>Remember\u2014you don\u2019t have to take on taxes all by yourself.
