Download California 100S Form

When filling out the California 100S form, it is essential to follow specific guidelines to ensure accuracy and compliance. Here are six important dos and don’ts to consider:

• Do read the instructions thoroughly before starting the form. Understanding the requirements can help prevent mistakes.
• Do double-check all calculations. Errors in numbers can lead to incorrect tax assessments or delays in processing.
• Do ensure all necessary schedules are attached. Missing documents can result in the return being considered incomplete.
• Do file the form electronically if possible. E-filing can expedite processing and reduce the chances of errors.
• Don’t use outdated forms. Always use the most current version of the 100S form to comply with the latest tax laws.
• Don’t overlook the importance of signatures. Ensure that all required signatures are present before submission to avoid rejection.

• Misconception 1: The California 100S form is only for large corporations.

This form is specifically designed for S corporations, which can vary in size. Even small S corporations must file this form if they meet the criteria set by California tax law.

• Misconception 2: Filing Form 100S guarantees a tax refund.

Filing the form does not automatically result in a refund. The outcome depends on the corporation's income, deductions, and tax liabilities.

• Misconception 3: All S corporations are exempt from paying taxes in California.

While S corporations may avoid double taxation, they are still subject to the minimum franchise tax and other state taxes.

• Misconception 4: The 100S form is the same as the federal Form 1120S.

Although both forms are for S corporations, they have different requirements and tax implications due to California's unique tax laws.

• Misconception 5: Only California residents can file Form 100S.

Non-resident S corporations that earn income in California must also file this form, regardless of their state of incorporation.

• Misconception 6: Filing extensions for Form 100S is not allowed.

Corporations can file for an extension using Form FTB 3539. However, any taxes owed must still be paid by the original due date.

• Misconception 7: All income must be reported on Form 100S.

Only income that is sourced to California or is otherwise subject to California tax needs to be reported on this form.

• Misconception 8: The 100S form can be filed on paper only.

California allows e-filing for Form 100S, making the process more efficient for many corporations.

• Misconception 9: There are no penalties for late filing of Form 100S.

Late filings can result in penalties and interest, so timely submission is important to avoid additional costs.

• Misconception 10: Once filed, the information on Form 100S cannot be changed.

If errors are found after submission, corporations can file an amended return using Form 100X to correct any mistakes.

The California 100S form is a crucial document for S corporations operating in California, as it serves as the state’s income tax return for these entities. In addition to the 100S form, several other forms and documents are often required to ensure compliance with state tax regulations. Below is a list of these associated forms, along with a brief description of each.

• FTB 3539: This form is used for making a payment for an automatic extension of time for filing the corporation's tax return, ensuring that the corporation does not incur penalties for late filing.
