What Form 3539 (2012) Is For

Form 3539 (2012) is a payment voucher used by corporations and specific exempt organizations to make tax payments when requesting additional time to file their California tax returns. It applies specifically to filers of Form 100, Form 109, and similar California tax forms regulated by the California Franchise Tax Board. While the state offers an automatic extension to file, it does not extend the time to pay. Form 3539 allows taxpayers to submit tentative franchise tax or income tax payments by the original due date, avoiding penalties and remaining in good standing.

When You’d Use Form 3539 (2012)

You would use Form 3539 (2012) when your return is not ready, but payment is due, and you want to maintain compliance with California tax laws.

You need extra time to file your corporate return

This applies when your business cannot complete its original return by the required due date but intends to file Form 100 or a similar return during the extension period.

You owe tax despite incomplete paperwork

You must submit payment for franchise tax or income tax by the original due date, even if you are waiting on data to finalize your return.

You operate an exempt organization

Entities filing Form 199, Form 109, or California Exempt Organization Annual Information Returns may owe tax on unrelated business taxable income and must use Form 3539 to pay.

You want to avoid penalty assessments

Timely payment through Form 3539 (2012) helps corporations prevent late payment penalties under the California Revenue and Taxation Code.

You file in a fiscal year rather than a calendar year

Corporations operating on a non-calendar budgetary year must calculate their original return deadline accordingly and use Form 3539 if they owe tax.

Key Rules or Details for 2012

Several non-negotiable requirements applied to the use of Form 3539 (2012) during the 2012 tax year.

You must pay your tax by the original due date

California grants an automatic extension to file, but not to pay; unpaid tax becomes subject to penalties and interest immediately.

Your entity must remain in good standing

Corporations suspended by the California Franchise Tax Board or forfeited by the California Secretary of State are not eligible for an automatic extension.

You must meet the minimum franchise tax requirements

All active corporations are required to pay the $800 minimum franchise tax, regardless of whether they are operating at a loss or only partially during the tax year.

You must accurately report identification numbers

Using incorrect entity information, such as FEIN or California corporation numbers, may delay processing and cause payment mismatches.

You must apply the payment to correct returns

This means ensuring that costs are associated with the correct forms, such as Form 100, Form 199, Form 109, or Form 990-PF.

Step-by-Step (High Level)

The process of using Form 3539 (2012) involves a few essential steps to ensure timely and accurate payment to the California Franchise Tax Board.

Calculate your tentative tax

Use the Tax Payment Worksheet provided with Form 3539 to estimate your total tax liability for the 2012 tax year, including the $800 minimum franchise tax where applicable.

Complete all identification fields

Enter your entity’s legal name, California corporation number, Secretary of State file number, Federal Employer Identification Number, and the correct tax year or fiscal year dates.

Determine whether electronic or paper payment applies

Corporations required to use electronic funds transfer due to prior large payments must not submit a paper check or voucher.

Prepare and send the payment

If paying by check or money order, write your corporation number, FEIN, and “2012 FTB 3539” on the payment and enclose it with the completed voucher.

Retain all records

Keep copies of Form 3539, payment documentation, and proof of mailing, as they are required for future reference and audit purposes by the Franchise Tax Board.

Common Mistakes and How to Avoid Them

Avoiding common filing and payment errors can help prevent delays and penalties associated with Form 3539 (2012).

Confusing an extension to file with an extension to pay

You can avoid this by understanding that California only extends the time to file, not the time to pay any tax owed.

Using incorrect entity numbers on Form 3539 (2012)

You can avoid this by confirming all entity details through the California Secretary of State and Franchise Tax Board records before submission.

Mailing the voucher to the wrong address

You can avoid this by checking the mailing address listed in the 2012 instructions, specifically for Form 3539, rather than using addresses for other forms.

Ignoring unrelated business taxable income for exempt organizations

You can avoid this by reviewing federal and state rules on income earned outside of exempt activities and reporting it correctly on Form 199 or Form 109.

Failing to confirm standing with the Registry of Charitable Trusts

You can avoid this by verifying that your organization is registered correctly and in compliance before claiming an automatic extension.

What Happens After You File

Once you submit Form 3539 (2012) with your payment, the Franchise Tax Board will process the voucher and credit the payment to your corporation’s account. You will not receive a confirmation notice, so it is essential to keep a copy of the voucher and proof of mailing as a record. If the payment was made electronically, an immediate confirmation receipt serves as your record. The extension gives you until the proper extended deadline to file your full return.

When you later file Form 100, Form 109, or another applicable return, include the Form 3539 payment on the designated line. If you overpaid, the excess may be refunded or applied to the next tax year; if you underpaid, interest will be assessed on the outstanding balance.

FAQs

Do I need to file Form 3539 (2012) if my corporation had no income and no tax due?

No, if your corporation had no income and your estimated payments covered your total liability, including the $800 franchise tax, you do not need to file Form 3539 (2012).

Can private foundations use Form 3539 (2012) for unrelated business taxable income?

Yes, private foundations with unrelated business taxable income must submit Form 3539 (2012) if tax is due by the original return date, even if they later file Form 990-PF.

How do I verify if my nonprofit is in good standing with the Registry of Charitable Trusts?

You can check your nonprofit’s registration and compliance status through the California Department of Justice’s Registry of Charitable Trusts online portal.

Is assistance available for filers using the California Relay Service?

Yes, the California Relay Service provides communication support for hearing- or speech-impaired taxpayers who need help with Form 3539 (2012) or other state filing requirements.

No, Form 3539 (2012) applies to entities doing business in California, and affiliation with the Greater London Authority or foreign incorporation does not exempt a corporation from payment or filing obligations.
