How to Pay the California Franchise Tax Board
What FTB payment means and who needs to make one
The Franchise Tax Board (FTB) is California's tax agency. When you owe California income tax, you send the payment to FTB, not to a local office or a federal agency. FTB collects state income tax from individuals and businesses, and they also handle other California taxes like the net operating loss carryover tax and the fiduciary income tax.
You may owe FTB a payment if you filed a California tax return and the amount you owe is larger than what was already withheld from your paychecks or paid through estimated tax installments. You might also owe if you're self-employed, received income FTB didn't know about, or claimed deductions that turned out to be wrong after an audit.
The payment itself is straightforward: you send money to FTB by a deadline they set. The method you choose—online, by mail, or through a payment plan—affects when FTB receives it and whether you face penalties for late payment.
Key Takeaways
- FTB accepts payments online through their website, by phone, by mail, or through an authorized payment processor, and online payments usually clear within one business day.
- The payment deadline is typically April 15 for income tax returns, but if you file late or owe after an audit, FTB will send you a notice with a new deadline.
- Paying late triggers a failure-to-pay penalty of 0.5% of the unpaid amount per month, plus interest that compounds daily, so even a few weeks of delay costs real money.
- If you cannot pay in full, you can set up a payment plan with FTB that lets you pay over time, though interest and penalties continue to accrue.
- FTB notices always include a payment due date and instructions; if you lose the notice, you can log into your FTB account online or call their payment line to confirm what you owe.
How to pay FTB online, by phone, or by mail
The fastest and most common method is to pay online through the FTB website at ftb.ca.gov. You'll need your Social Security number or federal employer identification number, your filing status, and the amount you owe. Online payments are processed the same day or the next business day, and FTB sends you a confirmation number immediately. There is no fee to pay through the FTB website itself.
If you prefer to pay by phone, you can call FTB's automated payment line. The phone number is on any notice FTB sends you, or you can find it on their website. Phone payments work the same way as online payments—you provide your tax information and the amount, and the payment is processed within one business day. Some people use this method because they want to speak with someone, though the automated system handles most payments without requiring a representative.
You can also pay by mail by sending a check or money order to the address listed on your FTB notice. Write your Social Security number and the tax year on the check. Mail payments take longer to reach FTB—typically five to ten business days depending on postal delays—so the payment date is the date FTB receives it, not the date you mail it. If you're close to the deadline, mailing is risky because a delayed letter means a late payment penalty.
Third-party payment processors like PayPal, Venmo, and credit card processors also accept FTB payments, but they charge a fee (usually 1.87% to 2.49% of the payment amount). These fees go to the processor, not to FTB, so you pay extra. Use these only if you need to pay with a credit card and cannot use the FTB website directly.
Understanding FTB payment deadlines and what happens if you're late
Your payment deadline depends on why you owe. If you filed your California income tax return on time (April 15 or the next business day if April 15 falls on a weekend), your payment is also due April 15. If you filed late, your payment deadline is the same as your filing deadline—usually 60 days after you file if you requested an extension.
If FTB audited your return or sent you a notice of tax due, the notice itself will show a payment deadline, usually 30 days from the date of the notice. Read the notice carefully because the deadline is not negotiable, and FTB counts the days strictly.
If you pay after the deadline, FTB charges a failure-to-pay penalty of 0.5% of the unpaid amount for each month (or part of a month) that the payment is late. So if you owe $1,000 and pay 45 days late, the penalty is roughly $15. FTB also charges interest on the unpaid balance, compounded daily at a rate set quarterly (currently around 8% per year, but this changes). Interest accrues from the original due date until FTB receives your payment, so the longer you wait, the more you owe in total.
If you cannot pay by the deadline, contact FTB before the deadline passes. Paying even one day late triggers the penalty, so it's better to set up a payment plan or ask about hardship relief before the date arrives.
Setting up a payment plan if you cannot pay in full
FTB offers installment agreements that let you pay what you owe over time instead of in one lump sum. You can request an installment agreement online through your FTB account, by phone, or by mail. The agreement specifies how much you'll pay each month and when each payment is due.
There is a setup fee to open an installment agreement, typically around $225 for online requests and higher if you request by phone or mail. This fee is added to what you owe. Once the agreement is in place, you make monthly payments on the schedule FTB sets. If you miss a payment, the agreement can be canceled and the full balance becomes due immediately.
Important: even while you're on a payment plan, FTB continues to charge interest and penalties on the unpaid balance. The plan doesn't stop those charges—it just lets you spread the payments out. So if you owe $5,000 and set up a 12-month plan, you'll pay more than $5,000 by the end because interest keeps accruing.
If you're facing genuine hardship—job loss, medical emergency, or other severe financial strain—you can ask FTB about Currently Not Collectible (CNC) status, which temporarily pauses collection efforts. This is not forgiveness; it means FTB stops trying to collect while you're in hardship, but interest and penalties still accrue, and collection resumes when your situation improves. CNC is harder to obtain than an installment agreement and requires documentation of your hardship.
What to do if you receive an FTB notice or bill
FTB sends notices by mail when you owe money. The notice includes the amount you owe, the deadline to pay, and instructions for payment. Read the entire notice because it may also explain why FTB believes you owe (for example, if it's from an audit or a correction to your return).
If you disagree with the amount, the notice will explain how to protest or request a hearing. You must do this before you pay if you want to challenge the bill. If you agree with the amount but need time, contact FTB to discuss a payment plan before the deadline.
If you've lost the notice or don't remember the amount, you can check your FTB account online by logging in with your Social Security number and creating or accessing your account. You can also call FTB's customer service line (the number is on their website) and provide your Social Security number to confirm what you owe and when it's due.
Keep records of every payment you make to FTB. Save confirmation numbers from online payments, keep copies of canceled checks or money order receipts, and hold onto any letters FTB sends acknowledging your payment. If there's ever a dispute about whether you paid, these records prove it.
How FTB payment relates to your credit and future tax returns
Unpaid California income tax does not directly appear on your credit report the way a credit card debt does. However, if you owe FTB for several years and don't pay, FTB can file a tax lien against you, which does affect your credit and makes it harder to borrow money or sell property. A lien is a legal claim on your assets until the debt is paid.
FTB can also offset future refunds. If you owe FTB and later file a return that results in a refund, FTB will keep the refund and apply it to what you owe. This happens automatically—you don't have to do anything, and you won't receive the refund check.
If you owe FTB and file a federal return, the IRS can also intercept your federal refund and send it to FTB to pay down your California debt. This is called federal offset, and it happens when FTB reports your debt to the U.S. Department of Treasury.

Frequently Asked Questions
Can I pay FTB with a credit card directly through their website?
No. The FTB website itself does not accept credit cards. You can pay with a debit card or bank account (ACH transfer). If you want to use a credit card, you must go through a third-party processor, which charges a fee of roughly 2% of the payment amount. Most people use a debit card or bank account to avoid the fee.
What happens if I pay FTB late by accident?
FTB charges a failure-to-pay penalty of 0.5% per month on the unpaid amount, plus daily interest. If you pay only a few days late, the penalty is small—usually a few dollars. If you realize you're late, pay as soon as possible to stop the interest from growing. You can request that FTB waive the penalty if you have a good reason (for example, a death in the family or a serious illness), but you must ask in writing and provide documentation.
Do I have to pay FTB if I disagree with the amount they say I owe?
No. If you receive a notice and disagree, you can file a protest or request a hearing before you pay. The notice will explain how to do this. However, if you wait too long to protest, you may lose the right to challenge it, so act quickly. You can pay while your protest is pending if you want to stop interest from accruing, and FTB will refund the overpayment if you win.
Can FTB take money from my bank account if I don't pay?
FTB cannot directly access your bank account without a court order. However, if you owe for several years and ignore notices, FTB can file a lien, get a judgment against you, and then use that judgment to garnish your wages or levy your bank account. This takes time and requires legal steps, but it is possible. Paying or setting up a plan before it reaches this point is much simpler.
What if I moved and didn't receive an FTB notice?
FTB mails notices to the address on file from your last return. If you moved, you should update your address with FTB as soon as possible. You can do this online through your FTB account or by calling their customer service line. If you missed a deadline because you didn't receive a notice, you can ask FTB to waive the penalty, but you'll need to show that you didn't receive it and that you updated your address promptly once you realized the problem.
