BURBANK, Calif. — Business owners in California facing their first tax filing in 2026 must familiarize themselves with various forms, deadlines, and requirements specific to the state. Understanding these elements can streamline the process and ensure compliance with both state and federal regulations.
Understanding the Basics of Business Taxes
In California, business taxes generally fall under two main categories: income tax and sales tax. Corporations, partnerships, and sole proprietorships all have different filing requirements. For instance, corporations must file an annual tax return, while sole proprietors report their business income on Schedule C of the IRS Form 1040.
Tax Identification Number (TIN)
Before filing taxes, businesses must obtain a Tax Identification Number (TIN) or Employer Identification Number (EIN). These can be acquired from the IRS online. As of 2023, applying for an EIN is free of charge and can be completed in minutes.
Key Tax Forms for California Businesses
Understanding which forms to file is crucial for compliance:
- IRS Form 1120/1120-S: Corporations must file Form 1120, while S Corporations use Form 1120-S. The deadline is typically the 15th day of the fourth month after the end of the tax year (April 15 for calendar-year filers).
- IRS Form 1040 with Schedule C: Sole proprietors report business income and expenses through Schedule C, filed with the owner's personal tax return.
- California Form 100: Corporations must submit Form 100 to the California Franchise Tax Board (FTB) by the due date of their federal return.
California State Taxes
In addition to federal taxes, California imposes a franchise tax on corporations. The minimum franchise tax for 2026 is $800 for most corporations, due annually, regardless of income. New corporations are exempt for their first tax year but must pay the tax starting the second year.
Filing Deadlines for 2026
Timeliness is crucial to avoid penalties. Popular filing deadlines include:
- Partnerships: March 15, 2026
- S Corporations: March 15, 2026
- C Corporations: April 15, 2026
- Individual Filers (Schedule C): April 15, 2026
Using IRS e-file options may expedite processing.
Sales Tax Compliance
Businesses selling goods in California must also collect sales tax and file sales tax returns. The state’s general sales tax rate is 7.25%, with local jurisdictions adding additional rates. Sales tax returns are usually due monthly or quarterly, depending on the amount of sales tax collected.
Record Keeping and Documentation
Accurate record-keeping is foundational for successful tax filing. Businesses should maintain:
- Receipts for all business-related expenses
- Invoices for revenue received
- Bank statements and payroll records
California law dictates retaining records for at least four years.
Common Mistakes to Avoid
First-time filers often make several common mistakes:
- Incorrect Forms: Using the wrong form can lead to delays and penalties. Always check IRS and California FTB guidelines.
- Missing Deadlines: Failing to file on time can result in late fees. Mark deadlines on calendars and set reminders.
