3586: Payment Voucher for Corps and Exempt Orgs e-filed Returns (2024)

Who files this form

Use Form FTB 3586 to pay tax due only if your corporation or exempt organization meets all four conditions:

• Files its tax return electronically.
• Has a balance due.
• Pays by check or money order.
• Is not required to pay electronically.

The text also says an LLC that elects to be taxed as a corporation for federal tax purposes must file FTB 3586 and enter its California corporation number, federal employer identification number (FEIN), and California Secretary of State (SOS) file number, if applicable. The LLC is treated as a corporation for these instructions.

Do not mail the voucher if no payment is due or if you pay electronically.

When it's due

For tax year 2024 calendar-year returns, the text lists these payment dates:

• Form 100 or 100W: April 15, 2025.
• Form 100S: The payment table lists March 15, 2025, while the voucher says calendar-year S corporations must file and pay by March 17, 2025. The text also says a deadline falling on a weekend or holiday extends to the next business day.
• Form 100 for farmers’ cooperatives: September 15, 2025.
• Form 109, generally: May 15, 2025.
• Form 109 for an employee’s trust under IRC 401(a) or an IRA: April 15, 2025.
• Form 199: May 15, 2025.

For tax year 2024 fiscal-year returns, payment is due after the close of the taxable year as follows:

• Form 100 or 100W: 15th day of the 4th month.
• Form 100S: 15th day of the 3rd month.
• Form 100 for farmers’ cooperatives: 15th day of the 9th month.

• Form 109 for an employee’s trust under IRC 401(a) or an IRA: 15th day of the 4th month.

Failure to pay the total tax liability by the original due date results in a late payment penalty plus interest. The FTB may waive the late payment penalty based on reasonable cause, but interest is mandatory.

Questions people ask

When is electronic payment required?

Corporations and exempt organizations that make an estimated tax or extension payment over $20,000, or have total tax liability over $80,000, must remit payments through electronic funds transfer. The first payment that triggers the requirement does not have to be electronic. After the threshold is met, all subsequent payments must be electronic, regardless of amount, tax type, or taxable year. Electronic funds withdrawal, Web Pay, and credit card payments also satisfy the requirement.

Can an exempt organization use electronic funds withdrawal?

Yes. An exempt organization can use electronic funds withdrawal to make a return payment when e-filing Form 109 or Form 199.

Can I schedule an online payment ahead of time?

Yes. Web Pay for Businesses lets corporations and exempt organizations make an immediate payment or schedule payments up to a year in advance. See ftb.ca.gov/pay.

Can the late payment penalty be waived?

The FTB may waive it based on reasonable cause. Reasonable cause is presumed when 90% of the tax shown on the return, but not less than the minimum franchise tax if applicable, is paid by the original due date. Interest is still mandatory.
