California’s electronic payment requirements attach to three different tax agencies, each with its own trigger. The Franchise Tax Board requires electronic payment once your income or business tax activity crosses a dollar threshold. The California Department of Tax and Fee Administration uses a rolling monthly average for sales, use, and special taxes. The Employment Development Department requires every employer to file and pay electronically with no threshold at all. Once you are covered, paying by check exposes you to penalties running from 1% to 10% of the payment.
Who Has to Pay Electronically
Whether the mandate applies to you depends on which tax you owe. The rules do not cross over: hitting the FTB threshold does not affect your CDTFA status, and vice versa. And once you are in, you generally stay in, even if your future payments are much smaller than the one that triggered the requirement.
FTB Thresholds for Income and Business Taxes
The Franchise Tax Board’s electronic payment mandate is triggered by either of two events:
- Filing an original return showing a total tax liability over $80,000, or
- Making any single estimated tax or extension payment over $20,000.
Cross either line once and every future payment to the FTB must be electronic, regardless of type, amount, or tax year. An estimated payment of $500 two years down the road still has to go through electronic channels. The payment that actually crosses the threshold does not itself need to be electronic; the obligation attaches to everything after it.
The same thresholds apply to corporations, S corporations, and LLCs classified as S corporations. The FTB counts total tax liability the same way for business entities, including any pass-through entity elective tax that pushes the total over $80,000.1Franchise Tax Board. S Corporation Pass-Through Entity Elective Tax and Mandatory E-Pay Requirement
Fiduciaries, estates, and trusts are not required to make electronic payments to the FTB.2Franchise Tax Board. Mandatory E-Pay for Individuals
Once you are a mandatory e-pay participant, the requirement covers every payment type to the FTB: individual income tax, corporate tax, estimated installments, extension payments, non-wage withholding, the annual LLC tax, and the pass-through entity elective tax.
CDTFA Thresholds for Sales, Use, and Special Taxes
The California Department of Tax and Fee Administration uses a rolling 12-month average instead of a single-event trigger. If your average monthly sales and use tax liability reaches $10,000 or more during the review period, you must remit by electronic funds transfer.3California Department of Tax and Fee Administration. California Code of Regulations Title 18 Section 1707 – Electronic Funds Transfer The CDTFA reviews this annually, so a business whose liability drops below the threshold in a given year can be removed from the mandate.
For special taxes and fees (categories outside sales and use tax, such as excise taxes, fuel taxes, alcoholic beverage taxes, and environmental fees), the threshold is higher: an average monthly liability of $20,000 or more over a 12-month period.4California Department of Tax and Fee Administration. Electronic Funds Transfer – Frequently Asked Questions
A successor business that takes over from a mandatory EFT participant inherits the requirement if the predecessor’s monthly liability met or exceeded the threshold.5Cornell Law Institute. Cal. Code Regs. Tit. 18, Section 4905 – Electronic Funds Transfer Buying an existing business means inheriting its EFT status along with everything else on the books.
The CDTFA mandate applies to both the underlying tax liability and any required prepayments.
EDD Mandate: Every California Employer
The Employment Development Department has no dollar threshold. Every California employer, including out-of-state employers with California employees, must file employment tax returns, wage reports, and payroll tax deposits electronically. This extends to any third-party representative filing or paying on an employer’s behalf.6Employment Development Department. E-file and E-pay Mandate for Employers
EDD penalties for paper filing are charged per item, which adds up fast for anyone with a real payroll:
- $50 per paper tax return (DE 9, DE 3D, DE 3HW)
- $20 per wage item on paper wage reports (DE 9C, DE 3BHW)
- 15% of the amount due for paper payments (DE 88)
These penalties apply even on a paper return reporting zero wages. Employers enroll through the EDD’s e-Services for Business portal, and new employer payroll tax account requests can take up to ten business days.7Employment Development Department. e-Services for Business
Payment Methods That Satisfy the Mandate
The mandate requires electronic payment, not one specific channel. For the FTB, four methods qualify: bank account payments through Web Pay, electronic funds withdrawal on an e-filed return, credit card, and pay-by-phone.2Franchise Tax Board. Mandatory E-Pay for Individuals Credit card payments carry a 2.3% service fee charged by the third-party processor, not the FTB.8Franchise Tax Board. Pay by Credit Card That fee is worth knowing about before putting a six-figure tax bill on plastic.
The CDTFA accepts ACH Debit (initiated through its online portal), ACH Credit (initiated through your bank), and credit card payments through its processor Fiserv, again with a 2.3% service fee.9California Department of Tax and Fee Administration. Credit Card Payment Program
ACH Debit means the state pulls funds from the bank account you register with them. ACH Credit means you tell your bank to push funds to the state. ACH Credit payments to the CDTFA must settle in the state’s account no later than one banking day after the due date to be considered timely, which usually means initiating the transfer two or three business days ahead.10California Department of Tax and Fee Administration. Notification to Pay by Electronic Funds Transfer
Penalties for Paying by Check When You Shouldn’t
The penalty for using the wrong payment method is separate from any late-payment penalty. It applies even when the check arrives on time.
FTB
An individual required to pay electronically who submits payment another way owes 1% of the amount that should have been paid electronically. For corporations and business entities, the penalty is 10% of the amount not paid electronically.11Franchise Tax Board. Common Penalties and Fees On a $100,000 corporate payment mailed as a check, that is a $10,000 penalty for the delivery method alone.
CDTFA
A mandatory EFT participant who remits sales and use taxes by check or other non-electronic method owes a 10% penalty on the amount incorrectly remitted. For prepayments, the penalty is 6%. The 10% penalty also applies if a mandatory participant files a return late, even when the tax itself was paid on time by EFT.12California Department of Tax and Fee Administration. Sales and Use Tax Law – Section 6479.3
Returned Electronic Payments
An electronic payment that bounces (insufficient funds, wrong account number) draws a separate penalty. The FTB charges 2% of the payment amount if the payment was $1,250 or more, or $25 (or the payment amount, whichever is less) if it was under $1,250.11Franchise Tax Board. Common Penalties and Fees
Waivers and Reasonable Cause
All three agencies offer waivers, but none are automatic. You have to ask, and you have to show that failure to pay electronically was due to reasonable cause and not willful neglect.
The FTB uses Form FTB 4107, the Mandatory e-Pay Waiver Request. Reasonable cause generally means you exercised ordinary business care and prudence and still could not comply, such as a bank system outage on the due date. The FTB may also waive the penalty if it determines that the payments that triggered the threshold were not representative of your typical liability.13Franchise Tax Board. FTB 1024 – Penalty Reference Chart California does not follow the IRS’s first-time abatement policy based on prior good filing history.14Franchise Tax Board. Reasonable Cause – Individual and Fiduciary Claim for Refund
The EDD’s waiver form is DE 1245W. It is available to employers who genuinely cannot file or pay electronically, but approved waivers last only one year, running from the quarter the request is received, and must be renewed each year the hardship continues.6Employment Development Department. E-file and E-pay Mandate for Employers
Not knowing about the requirement does not count as reasonable cause. Each agency sends a notification letter when you become a mandatory participant, and the obligation is treated as established from that date. If you receive one of those letters, get your electronic payment setup completed before the next filing period rather than the week of the deadline.
