What Form 100 (2019) Is For
Form 100 (2019) is the California Corporation Franchise or income tax return used by corporations to report income taxes to the California Franchise Tax Board for the 2019 taxable year. This income tax return reports taxable income, net income, and tax liabilities under California tax law and is based in part on figures from the federal return. It serves as the state-level filing tied to federal purposes while applying California-specific rules that differ from federal tax law administered by the federal government.
When You’d Use Form 100 (2019)
Corporations are required to file Form 100 (2019) in several everyday filing situations tied to California income and franchise tax obligations.
- Original corporate income tax return filing: A corporation must file Form 100 (2019) to report current year income, taxable income, and income taxes owed for applicable taxable years.
- Domestic and foreign corporation activity: Domestic corporations and foreign corporations that are incorporated, registered, or doing business in California must file when California sourcing thresholds are met.
- Entity classification confirmation: Businesses classified as a C corporation must use Form 100, while limited liability companies taxed as corporations must verify whether Form 100 or Form 568 applies.
- First-year filing requirement: Corporations in their first year of existence may still be required to file Form 100 even if operations were limited or inactive.
- Corrections tied to federal reporting: Changes to the federal return or federal tax purposes may require a revised California filing to maintain compliance.
Key Rules or Details for Tax Year 2019
Filing Form 100 (2019) requires corporations to follow several tax rules that apply specifically to the 2019 tax year under California law.
- Minimum franchise tax obligation: Most corporations are subject to the minimum tax regardless of profitability or net income for the year.
- Federal conformity limitations: California does not fully conform to federal tax law, which requires adjustments when federal provisions differ from state rules.
- Federal starting point calculations: Amounts reported on the federal Form 1120 are used as a baseline before applying California modifications.
- Credits and adjustments: Tax credits such as FTB 3805Q may reduce tax liabilities but cannot lower the amount owed below the minimum tax.
- Advanced tax considerations: This means net operating loss limits, Alternative Minimum Tax rules, and Section 179 Expense Deduction differences must be carefully evaluated.
- Official guidance sources: Instructions from Tax Forms publications and FTB Pub materials provide clarification on reporting requirements and compliance expectations.
Step-by-Step (High Level)
Filing Form 100 (2019) involves a structured process that builds from federal reporting and applies California-specific tax rules.
- Gather financial and tax records: Corporations should collect accounting records, prior-year filings, documentation of tax payments, and supporting schedules needed for accurate reporting.
- Complete the federal return first: The federal return establishes baseline figures for federal purposes and must be finalized before preparing the California filing.
- Calculate California taxable income: Corporations must adjust federal amounts to determine California taxable income under state tax law.
- Apply credits and reconcile payments: Estimated tax payments and allowable tax benefits must be applied correctly to calculate remaining tax liabilities.
- File and submit payment by the deadline: Form 100 (2019) must be filed by the 15th day of the required filing month, along with any payment due.
Common Mistakes and How to Avoid Them
Corporations frequently make filing errors that can result in notices, penalties, or delayed processing by the California Franchise Tax Board.
- Misreporting income taxes: Corporations should reconcile income taxes reported on the federal return with California adjustments before filing.
- Using the incorrect tax form: Businesses must confirm whether Form 100 or Form 568 applies based on entity classification and tax treatment.
- Overlooking federal law differences: California requires specific adjustments when federal tax purposes do not align with state rules.
- Improper credit application: Tax credits must be calculated and applied within statutory limits to avoid underpayment issues.
- Risky tax avoidance positions: Corporations should avoid unsupported tax avoidance strategies that may trigger review or audit activity.
What Happens After You File
After Form 100 (2019) is filed, the California Franchise Tax Board reviews the income tax return for accuracy, completeness, and proper payment. If additional tax liabilities are identified, the FTB will issue a notice outlining the amount due, including interest and penalties. Refunds are issued once processing is complete. Correspondence may be mailed to the address on file or directed to PO Box 942857 for responses. Corporations should retain records in case additional documentation is requested.
