Homepage Blank California 100X PDF Form
Article Guide

The California 100X form serves as an essential tool for corporations looking to amend their previously filed franchise or income tax returns. This form allows corporations to correct errors, report changes, or claim refunds due to overpayments. It is specifically designed for use with the original Form 100, Form 100W for water's-edge filers, or Form 100S for S corporations. When completing the 100X, corporations must provide key information such as their California corporation number, federal employer identification number, and details about the taxable year for which they are amending their return. The form includes sections for reporting income and deductions, computing taxes, and detailing any penalties or interest. Additionally, corporations must explain the changes being made in a dedicated section, ensuring that all supporting documents are attached. Filing this form is crucial for maintaining compliance with California tax laws and can significantly impact a corporation’s financial standing.

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:

Filing Form 100X, Am ended Corporation Incom e Tax Return; or

Sending a letter w ith copies of the federal changes to:

CORPORATION RAR FRANCHISE TAX BOARD PO BOX 942857

SACRAM ENTO CA 94257- 0501

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. Please note that m ost penalties assessed by the IRS also apply under California law. If penalties are included in a paym ent w ith the am ended return, see the instructions for line 19, Penalties and Interest.

C Where to File

Tax Due

If tax is due, and the corporation is not required to use electronic funds transfer (EFT), m ake check or m oney order payable to the Franchise Tax Board. Write the California corporation num ber and ‘’2001 Taxable Year Form 100X’’ on the check or m oney order.

M ail Form 100X w ith the check or m oney order to:

FRANCHISE TAX BOARD PO BOX 942857

SACRAM ENTO CA 94257- 0501

Note: If the corporation m ust pay its tax liability using EFT, all paym ents m ust be rem itted by EFT to avoid penalties. See the instructions for line 28, Am ount Due.

M ail Form 100X to:

FRANCHISE TAX BOARD PO BOX 942857

See federal Form 1120, U.S. Corporation Incom e Tax Return, for a list of designated deliver y ser vices. Private delivery ser vices cannot deliver item s to PO boxes. If using one of these ser vices to m ail any item to the FTB, DO NOT use an FTB PO box. Address the am ended tax return to:

FRANCHISE TAX BOARD

Your Questions, Answered

What is the purpose of the California 100X form?

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, report changes in income or deductions, or claim a refund for overpaid taxes. It applies to Form 100, Form 100W, or Form 100S, depending on the corporation's status. Filing this form ensures compliance with California tax laws and allows corporations to rectify any discrepancies in their tax filings.

When should I file the California 100X form?

File the California 100X form only after the original tax return has been submitted. Corporations must submit this amended return within four years from the original due date, the date the tax return was filed, or within one year from the date the tax was paid, whichever is later. If the IRS audits the federal corporate tax return and changes it, report these changes to the Franchise Tax Board (FTB) within six months of the final federal determination.

Where do I send the California 100X form?

If the amended return results in a refund or no amount due, mail it to: Franchise Tax Board, PO Box 942857, Sacramento, CA 94257-0500. If there is an amount due, send it to: Franchise Tax Board, PO Box 942857, Sacramento, CA 94257-0501. Ensure that all payments are made correctly to avoid penalties. If using a private delivery service, do not use a PO box; instead, address it to Franchise Tax Board, Sacramento, CA 95827.

What information is required on the California 100X form?

When completing the California 100X form, provide the corporation's name, address, California corporation number, and Federal Employer Identification Number (FEIN). Additionally, indicate whether the return is amended based on a final federal determination and provide an explanation of changes made. Include supporting documentation for any adjustments, such as federal schedules or other relevant forms. This information is crucial for the FTB to process the amended return accurately.

Common mistakes

  1. Incorrect Tax Year: Failing to accurately indicate the taxable year can lead to significant issues. It is crucial to enter the correct beginning and ending dates for the year being amended.

  2. Missing Federal Determination Information: If the amended return is based on a final federal determination, individuals often forget to provide the date of that determination. This omission can delay processing.

  3. Not Checking the Right Boxes: Many people overlook the importance of marking the correct boxes for the type of amended return being filed, such as Form 100, Form 100W, or Form 100S. This can result in the return being processed incorrectly.

  4. Inadequate Explanation of Changes: When detailing changes made in the amended return, individuals sometimes provide insufficient information. A clear and thorough explanation is essential to avoid confusion and ensure proper processing.

  5. Failure to Attach Supporting Documents: Not including necessary supporting forms and schedules can lead to delays or rejections. It's important to attach all relevant documents that substantiate the changes made on the return.

Documents used along the form

The California Form 100X is an important document used by corporations to amend previously filed tax returns. When filing this form, it is often necessary to include additional forms and documents to ensure that all relevant information is properly reported. Below is a list of other forms and documents that are commonly used alongside the California 100X form, along with brief descriptions of each.

  • Form 100: This is the original California Corporation Franchise or Income Tax Return. Corporations file this form to report their income, deductions, and tax liability for the taxable year. If there are any changes or corrections needed after filing, the 100X form is used to amend it.
  • Form 100W: This form is specifically for corporations that elect to file as Water’s-Edge Filers. It is used to report income and calculate taxes for corporations that operate both within and outside California, allowing them to exclude certain foreign income from taxation.
  • Form 100S: This is the California S Corporation Franchise or Income Tax Return. S corporations use this form to report income, deductions, and other tax-related information. If an S corporation needs to amend its return, it would use the 100X form.
  • Form 1120X: This is the federal amended corporate income tax return. Corporations use this form to amend their federal tax returns when there are changes to income, deductions, or credits. Changes made on the federal return may necessitate amendments on the California return as well.
  • Schedule R: This schedule is used by corporations that apportion their income to California. It helps determine how much of the corporation's income is subject to California tax based on its business activities within the state.
  • Form FTB 3834: This form is used to compute interest under the look-back method for completed long-term contracts. If a corporation has changes related to long-term contracts, this form may need to be filed alongside the 100X.
  • Form FTB 3560: This form is used for S Corporation Election or Termination. If a corporation is changing its status from a C corporation to an S corporation, or vice versa, this form must be filed, but it is not included with the 100X.

Each of these forms plays a crucial role in ensuring that corporations comply with both state and federal tax laws. By using the California Form 100X in conjunction with these additional documents, corporations can accurately report their financial information and make necessary corrections to previous filings. This process helps maintain transparency and compliance with tax regulations.

Similar forms

  • Form 1120X: This is the U.S. Corporation Income Tax Return Amended. Like the California 100X form, it is used to correct errors on a previously filed tax return. Both forms require detailed explanations of the changes made and support documentation.
  • Form 100W: This is the California Corporation Franchise or Income Tax Return for Water's-Edge Filers. Similar to the 100X, it addresses the income tax obligations of corporations operating in California, but specifically for those electing to report on a water's-edge basis.
  • Form 100S: This form is for California S Corporations. Like the 100X, it allows for amendments to previously filed returns. Both forms require corporations to report changes in income or deductions, ensuring accurate tax reporting.
  • Form 941X: This is the Adjusted Employer's QUARTERLY Federal Tax Return or Claim for Refund. Similar to the 100X, it is used to amend a previously filed return, specifically for payroll taxes, and requires an explanation of changes.
  • Form 4868: This is the Application for Automatic Extension of Time to File U.S. Individual Income Tax Return. While it serves a different purpose—extending the filing deadline—it shares the need for accurate reporting and compliance with tax obligations, similar to the 100X process.

Dos and Don'ts

When filling out the California 100X form, there are several important dos and don'ts to keep in mind. These guidelines can help ensure that your form is completed accurately and submitted correctly.

  • Do double-check all the information entered on the form for accuracy.
  • Do include all necessary supporting documents and schedules when submitting your amended return.
  • Do clearly explain any changes made in Part V, providing detailed reasons and line references.

  • Don't use this form to change your corporate status; file the appropriate form for that purpose.
  • Don't leave any required fields blank; ensure all questions are answered.
  • Don't submit the form to a PO box if using a private delivery service; use the correct physical address instead.

Misconceptions

  • Misconception 1: The California 100X form can be filed at any time.
  • This is incorrect. The 100X form must be filed within four years from the original due date of the tax return or one year from the date the tax was paid, whichever is later.

  • Misconception 2: You can use the 100X form to change the corporate filing status.
  • This is not true. To change corporate status from a C corporation to an S corporation, or vice versa, a different form, FTB 3560, must be filed.

  • Misconception 3: Filing a 100X form guarantees a refund.
  • Filing the 100X does not guarantee a refund. It is merely a request for an adjustment based on changes made to the original return.

  • Misconception 4: You don’t need to attach supporting documents when filing the 100X form.
  • This is misleading. It is essential to include all supporting forms and schedules for any items that have changed, including federal schedules if applicable.

  • Misconception 5: The 100X form can be filed before the original return.
  • This is incorrect. The 100X form should only be filed after the original tax return has been submitted.

  • Misconception 6: You can file the 100X form electronically.
  • As of now, the 100X form must be mailed to the Franchise Tax Board; electronic filing is not available for this form.

  • Misconception 7: There are no penalties for late filing of the 100X form.
  • This is false. If the form is filed late, the corporation may still incur penalties, particularly if there are unpaid taxes.

  • Misconception 8: You can file the 100X form for any reason.
  • This is misleading. The 100X form is specifically for amending a previously filed Form 100, 100W, or 100S, and should be used only for valid reasons such as corrections or changes in federal returns.

  • Misconception 9: You can ignore the IRS changes when filing the 100X form.
