Filing Form 1120S is a complex process, but it's essential for S corporations to report their income, deductions, and credits to the Internal Revenue Service (IRS). Failure to file or inaccurate filing can result in severe penalties, including fines and even the loss of S corporation status.

What is an S Corporation?

Before we dive into the details of filing Form 1120S, let's briefly discuss what an S corporation is. An S corporation is a type of corporation that elects to pass corporate income, losses, deductions, and credits to its shareholders for federal tax purposes. This means that S corporations are not subject to corporate-level income tax, and instead, the shareholders report their share of the corporation's income and expenses on their personal tax returns.

Benefits of Filing Form 1120S

Filing Form 1120S provides several benefits to S corporations, including:

• Pass-through taxation: S corporations are not subject to corporate-level income tax, reducing the tax burden on the business.
• Reduced self-employment tax: Shareholders who work for the corporation may be able to reduce their self-employment tax liability.
• Flexibility in ownership: S corporations can have up to 100 shareholders, allowing for more flexibility in ownership structure.

The following entities must file Form 1120S:

• S corporations: Any corporation that has elected S corporation status must file Form 1120S.
• Domestic corporations: Only domestic corporations can file Form 1120S.
