IRS extension instructions ↗OC TAX FILING · ORANGE COUNTY
Missing a tax document? We help Orange County individuals request a federal filing extension and estimate federal and California payments separately. Work with us in Costa Mesa or remotely, then set a date to finish your return.
HOW WE HELP
An extension gives you more time to finish your return. It generally does not give you more time to pay. We use the figures you have to estimate the balance after withholding and payments you already made.
For a federal individual return, we can prepare Form 4868 when appropriate. California generally grants individuals an automatic filing extension without an application. We check federal and state payment needs separately.
WHAT WE CAN DISCUSS
The exact work is confirmed before your preparation begins.

IRS extension instructions ↗CALIFORNIA · FTB
California’s individual filing extension is automatic. If you owe tax, choose “extension payment” and the correct tax year in Web Pay, or mail your payment with that year’s FTB 3519 voucher. If you owe nothing, skip the voucher.
Already past the extended deadline? Tell us which year you missed and whether you received a notice. See help with unfiled returns.
GET READY
Use this list as a starting point. We may need other records after learning more about your situation.
Do not send private documents through the contact form. Ask how to share them before sending.
PRICING
Our tax preparation services start at $125. Your quote for this service depends on the work needed. We confirm the fee and included returns before starting.
We quote the extension work separately from preparing your final return.
Discuss your return ↗AFTER THE EXTENSION
Write down the filing deadline and schedule your review several weeks earlier. Keep federal and state payment confirmations with your records.
List each missing document and who will send it. For example, if you are waiting on a corrected 1099, contact the payer and set a reminder to check back.
Match extension payments to the final returns. Review the refund or remaining balance, authorize filing and keep the filing confirmations. You can finish as soon as your records are ready.
Generally, no. California gives individuals an automatic six-month extension to file. FTB 3519 is a payment voucher for mailing an extension payment, not an extension application. You do not mail the voucher if you pay through Web Pay.
No. Under the ordinary rules, your estimated unpaid federal and California taxes are due by the original deadline. A late payment can result in interest and penalties even when the return itself is filed on time.
For most calendar-year individuals, request the federal extension by the regular April filing deadline and file the completed return by the extended October deadline. For tax year 2025, those dates were April 15 and October 15, 2026. Check the dates for your own tax year; disaster postponements and special filing rules can change them.
You can generally still request a filing extension. Paying what you can by the original deadline may reduce interest and penalties.
Tell us the year and whether you already requested an extension. If your applicable deadline passed without one, we can discuss preparing the outstanding return.
