In addition to Form 1120S, you may also need to complete several schedules, depending on the company’s activities and circumstances. The most common schedules are:

Schedule K-1: Shareholder’s Share of Income, Deductions, Credits, etc.

4 : Deadlines and Other Considerations


The deadline for filing Form 1120S is March 15th of the following year, unless the company has filed for an extension. If an extension is granted, the deadline is September 15th. It is important to note that even if the company is not required to pay any tax, it must still file a tax return by the deadline.

If the company owes taxes, it can make estimated tax payments throughout the year to avoid penalties and interest. These payments are typically made quarterly and are based on the company’s expected tax liability for the year.

It is also important to maintain accurate records and documentation to support the information reported on Form 1120S. This includes keeping track of all income and expenses, as well as any tax forms or schedules.

In the event of an audit or other inquiry by the IRS, the company may be required to provide additional documentation to support the information reported on the tax return. It is important to keep these records organized and readily accessible.

Conclusion


Completing Form 1120S can be a complex process, but with the right information and documentation, it can be done accurately and efficiently. It is important to understand the requirements for each section of the form, as well as any applicable schedules, deadlines, and other considerations.
