Instructions for Form 100X
Amended Corporation Franchise or Income Tax Return
General Information
Income year vs. taxable year
Effective for years beginning on or after Januar y 1, 2000, references to “ incom e year” w ere replaced w ith “ taxable year” in all provisions of the Corporation Law (CTL), the Adm inistration of the Franchise and Incom e Tax Law (AFITL), and the Personal Incom e Tax Law (PITL) . When referring to an incom e
m easurem ent period beginning before Januar y 1, 2000, the term “ taxable year” should be interpreted to m ean “ incom e year” .
Statute of limitation
California Revenue and Taxation Code Section 19306 w as am ended to provide that the statute of lim itation (SOL) for a refund w ill be four years from the later of the original due date or the date the tax return w as filed. This law change is effective for any year w ith an open SOL for issuing a refund as of Januar y 1, 2000. If the tax return is delinquent, the SOL for refund w ill revert back to four years from the original due date, not the extended due date.
Preparer Tax Identification Number (PTIN) Beginning Januar y 1, 2000, tax professionals have the option of providing their individual Social Security Num ber (SSN) or Preparer Tax Identification Num ber (PTIN) on returns they prepare. Preparers w ho w ant a PTIN m ust com plete and subm it federal Form W- 7P, Application for Preparer Tax Identification Num ber, to the IRS.
A Purpose
Use Form 100X to am end a previously filed Form 100, California Corporation Franchise or Incom e Tax Return; Form 100W, California Corporation Franchise or Incom e Tax Return – Water’s- Edge Filers; or Form 100S, California S Corporation Franchise or Incom e Tax Return.
A claim for refund of an overpaym ent of tax should be m ade by filing a Form 100X.
If the corporation is filing an am ended tax return in response to a billing notice the corporation received, the corporation w ill continue to receive billing notices until the am ended tax return is accepted. In addition, the corporation m ust pay the assessed tax before the corporation can claim a refund for any part of the assessed tax.
Note: Do not use this form to change the corporate filing status. If changing corporate status from a C corporation to an S corpora- tion, or vice versa, file form FTB 3560,
S Corporation Election or Term ination/ Revocation.
Unless other w ise stated, the term “ corpora- tion” as used in Form 100X and in these instructions includes banks, financial corporations, S corporations, exem pt
hom eow ners’ associations, political organiza- tions, lim ited liability com panies; and lim ited liability partnerships classified as corporations.
B When to File
File Form 100X only after the original tax return has been filed. Corporations m ust file a claim for refund w ithin four years from the original due date of the tax return, the date the tax return w as filed, or w ithin one year from the date the tax w as paid, w hichever is later. Tax returns filed before the due date are considered as filed on the original due date.
If the federal corporate tax return is exam ined and changed by the Internal Revenue Ser vice (IRS), report these changes to the Franchise Tax Board (FTB) w ithin six m onths of the final federal determ ination by either:

With either m ethod, you m ust include a copy of the final federal determ ination, all underly- ing data and schedules that explain or support the federal adjustm ents.

If penalties are included in a paym ent w ith the am ended return, see the instructions for line 19, Penalties and Interest.

Page 2 Form 100X 2001
Filling out the California 100X form is an essential step for corporations looking to amend their previously filed tax returns. This process involves providing updated information and corrections to ensure compliance with state tax regulations. By following these steps, you can accurately complete the form and submit it to the Franchise Tax Board.
Once the form is submitted, keep a copy for your records. This will help in case of any future inquiries or audits. Be sure to monitor the status of your amended return and respond promptly to any requests from the Franchise Tax Board.
The California 100X form is used to amend a previously filed California Corporation Franchise or Income Tax Return. Corporations file this form to correct errors, claim refunds, or report changes based on federal determinations.
You should file the 100X form only after you have submitted your original tax return. The form must be filed within four years from the original due date of the return, the date the return was filed, or within one year from the date the tax was paid, whichever is later.
If you are expecting a refund or do not owe any tax, mail the completed form to:
If you owe tax, send the form to:
You will need details from your original tax return, including your corporation name, California corporation number, and any changes you are making to income, deductions, or credits. You should also include any supporting documentation for the changes.
No, the 100X form cannot be used to change your corporation's filing status. If you need to change your status from a C corporation to an S corporation or vice versa, you must file Form FTB 3560.
If the IRS audits your original return and makes changes, you must report these changes to the Franchise Tax Board within six months of the final federal determination. You can do this by filing the 100X form or sending a letter with the necessary documentation.
Filing the 100X form late may result in the loss of your right to claim a refund. The statute of limitations for refunds is generally four years from the original due date or the date the return was filed, whichever is later.
Yes, there may be penalties for late filing or underpayment of taxes. If you owe penalties or interest, you must report them on the 100X form. The Franchise Tax Board will calculate the interest due if not provided.
Incomplete Information: One common mistake is failing to provide complete information on the form. Ensure that all sections are filled out accurately, including the corporation name, address, and California corporation number. Missing or incorrect information can lead to delays or rejections of the amended return.
Incorrect Tax Year: Many individuals mistakenly select the wrong taxable year. It is crucial to confirm that the year specified matches the year for which the amendment is being filed. This error can complicate the processing of the return and may result in penalties.
Failure to Attach Supporting Documents: Another frequent oversight is not attaching necessary supporting documents. When changes are made, it is essential to include any relevant schedules, forms, or federal documents that justify the amendments. Without these attachments, the Franchise Tax Board may not accept the return.
Neglecting to Sign the Form: A simple yet critical mistake is forgetting to sign the amended return. The form must be signed by an authorized officer of the corporation. An unsigned form is considered incomplete and will not be processed.
The California 100X form is an essential document for corporations that need to amend their previously filed tax returns. When dealing with tax matters, various other forms and documents often accompany the 100X to ensure compliance and accuracy. Below is a list of commonly used forms that may be relevant in conjunction with the California 100X form.
Each of these forms plays a crucial role in the tax filing process for corporations in California. Understanding their purpose and how they relate to the California 100X form can help ensure that all necessary adjustments and claims are properly documented and submitted. Properly managing these forms can lead to more accurate tax filings and potentially avoid issues with the Franchise Tax Board.
The California Form 100X is similar to the IRS Form 1120X, which is the Amended U.S. Corporation Income Tax Return. Both forms are used to amend previously filed tax returns, allowing corporations to correct errors or make changes based on new information. The 1120X requires corporations to provide an explanation of the changes, similar to the 100X's requirement for detailing adjustments in income and deductions. Both forms also facilitate claims for refunds resulting from these amendments.
Another similar document is the California Form 100W, which is specifically for Water's-Edge Filers. Like the 100X, the 100W allows corporations to amend their tax returns. The main difference is that the 100W is tailored for corporations that elect to limit their taxable income to income from within the United States and certain foreign income. Both forms require corporations to indicate the reason for the amendment and provide supporting documentation.
The California Form 100S, used for S Corporations, is also akin to the 100X. It enables S Corporations to amend their tax returns in a similar manner. Both forms require detailed explanations of changes made to income and deductions. Additionally, both forms address the need for corporations to report any changes made by the IRS that affect their tax obligations.
Form 1040X, the Amended U.S. Individual Income Tax Return, is another document that shares similarities with the California Form 100X. While 1040X is for individual taxpayers, both forms allow for corrections to previously filed returns. They each require an explanation of the changes made and the rationale behind those adjustments, ensuring transparency in the amendment process.
The IRS Form 941-X, Adjusted Employer’s QUARTERLY Federal Tax Return or Claim for Refund, is also comparable. This form is used to amend previously filed quarterly payroll tax returns. Like the 100X, it allows taxpayers to correct errors and claim refunds for overpayments. Both forms emphasize the importance of providing a clear explanation of the changes made.
California Form 568, which is used by Limited Liability Companies (LLCs) to report income, is similar in function to the 100X. If an LLC needs to amend its previously filed return, it uses Form 568. Both forms require the taxpayer to explain changes and provide supporting documents, ensuring that the amended return is complete and accurate.
Lastly, IRS Form 8862, Information to Claim Earned Income Credit After Disallowance, has similarities in that it allows taxpayers to amend their claims for credits after a disallowance. While it serves a different purpose than the 100X, both forms require taxpayers to provide detailed explanations and supporting documentation to substantiate their claims or amendments.
When filling out the California 100X form, here are ten important do's and don'ts to keep in mind:
This form is specifically for amending previously filed tax returns. To change corporate status, a different form must be used.
Filing this form does not automatically result in a refund. It only amends the tax return, and a refund depends on the changes made.
Corporations must file the 100X form within four years from the original due date of the tax return or one year from the date the tax was paid.
This form can be filed whether there is a tax due or if the corporation is claiming a refund.
Corporations must report changes made by the IRS to the Franchise Tax Board within six months of the final federal determination.
Each tax year requires a separate 100X form. You cannot amend multiple years in a single submission.
Currently, the 100X form must be mailed to the Franchise Tax Board. Electronic filing is not available for this form.
