Hi, I’m Bette Hochberger, CPA, CGMA. For S corporations, the filing of Form 1120S is a crucial step in meeting federal tax obligations. This blog aims to cover the process and provide step-by-step insights into completing Form 1120S. Whether you’re an S corporation or an LLC taxed as an S corp, this guide will help you navigate the intricacies of this essential tax document.

Understanding Form 1120S

Form 1120S is specifically designed for S corporations, offering a distinct approach compared to the more common Form 1120 used by C corporations. S corporations, including those structured as LLCs, must use Form 1120S to report income, deductions, credits, and other relevant information to the IRS.

Key Components 

Basic Information

Begin by providing the essential details about your S corporation, such as its name, address, Employer Identification Number (EIN), and the date the corporation was established.

Income and Deductions

Outline the corporation’s income and deductions accurately. This includes business revenue, cost of goods sold, operating expenses, and any other sources of income or deductions.

Shareholder Information

List the names, addresses, and Social Security numbers of all shareholders. Make sure that the ownership percentages are accurately reflected.

Built-In Gains and Excess Net Passive Income

S corporations need to report any built-in gains or excess net passive income. Understanding these concepts is crucial for tax planning and compliance.

Tax Credits and Payments

If applicable, report any tax credits your S corporation is eligible for, and detail any estimated tax payments made throughout the tax year.

Schedule K-1

Shareholders receive a Schedule K-1, detailing their share of the corporation’s income, deductions, and credits. Ensure accuracy in completing and distributing these forms.
