Missing a tax deadline can lead to penalties, interest, and unnecessary stress. At Local Tax, we’ve created this Tax Due Dates guide to help individuals and business owners in Bellflower and throughout Los Angeles County stay on top of key filing deadlines for federal and California state taxes.
Whether you prepare your taxes yourself or work with a professional, knowing the important dates each year helps you avoid surprises and penalties.
January 15
Estimated quarterly tax payment due for self-employed individuals and business owners (fourth quarter of previous year).
January 31
Deadline for employers to issue:
March 15
Business tax return deadline for:
April 15
Individual tax return deadline (Form 1040)
If the date falls on a weekend or holiday, the deadline may shift to the next business day.
June 15
Estimated quarterly tax payment due for individuals and business owners (second quarter).
September 15
Estimated quarterly tax payment due (third quarter).
October 15
Extended deadline for individual tax returns that were filed under extension.
January 15 (following year)
Final estimated payment due for the year if you file an extension.
These deadlines apply to federal tax returns unless the IRS announces an extension or change due to events like natural disasters.
California income tax deadlines generally match federal deadlines, but it’s important to verify each year with the California Franchise Tax Board.
If you have questions about California deadlines or payment schedules, we can review your specific situation.
If you are self-employed, own a business, or receive income not subject to withholding (like contract work or rental income), you may need to pay estimated quarterly taxes.
Typical estimated tax payment dates are:
Failing to pay estimated taxes can result in underpayment penalties.
Extension Requests
If you cannot file your tax return by April 15, you can file for an extension. The extended filing deadline is usually October 15 for personal returns. This gives you more time to file, but it does NOT extend the time to pay any taxes owed.
Payroll Tax Deadlines
Businesses with employees have separate payroll tax deposit deadlines that may be weekly, semi-weekly, or monthly. These depend on the size of your payroll and your filing history.
Sales Tax Deadlines
Businesses that collect sales tax must follow California reporting and payment schedules that may be monthly, quarterly, or annually, based on your volume of sales.
Failing to meet tax due dates can result in:
Penalties can add up quickly. Even if you can’t pay the full amount, filing on time and contacting the tax agency to set up a payment plan often minimizes penalties.
Keeping track of multiple deadlines is challenging, especially if your income sources change, you own a business, or you’ve had major life events.
