Where to pay California taxes online

California offers two main online payment channels: the Franchise Tax Board (FTB) website for income tax, and the Department of Tax and Fee Administration (CDTFA) website for sales tax and other fees. Most individual taxpayers use the FTB portal at onlineservices.ftb.ca.gov, which accepts payments for current-year returns, prior-year returns, and estimated tax payments. If you owe sales tax or excise tax, you'll use the CDTFA portal instead.

Both portals accept payments directly from your bank account (ACH transfer) or by credit or debit card. The state does not charge a fee for ACH transfers, but credit and debit card payments include a processor fee — typically 1.87% to 2.49% of the amount paid, depending on which payment processor handles your transaction. You can see the exact fee before you confirm the payment.

You do not need to create an account beforehand, though creating one lets you save payment history and set up recurring payments for estimated taxes. First-time payers can proceed as guests and complete a single payment in one session.

Key Takeaways

  • Income tax payments go through the FTB website; sales tax and excise tax payments go through the CDTFA website.
  • ACH transfers from your bank account are free, but credit and debit card payments charge a processor fee of roughly 2% of the amount.
  • Payments typically post to your account within one to three business days, though the state may take longer to process and explore the payment to your specific tax year.
  • You can pay before filing your return, after filing, or on the payment important date — the state will match the payment to your account once your return is processed.
  • If you miss the important date, you can still pay online; late payments accrue penalties and interest starting the day after the important date.

Step-by-step: paying income tax through the FTB

Go to onlineservices.ftb.ca.gov and select "Make a Payment" from the homepage. You will see two options: "Pay as a Guest" or "Sign In." Guests can make a one-time payment without creating an account; signing in lets you view payment history and manage recurring payments.

Enter your Social Security Number (or Individual Taxpayer Identification Number) and the tax year you're paying for. The system will ask for the amount you want to pay. You can pay the full amount due, a partial payment, or an estimated tax installment. Next, choose your payment method: ACH transfer (free) or credit/debit card (with processor fee shown upfront).

If you choose ACH, provide your bank's routing number and your account number. If you choose a card, enter the card details. Review the payment summary, including the fee if applicable, and confirm. The FTB will display a confirmation number when ready — save or print this for your records. The payment typically posts to your bank account within one to three business days.

Step-by-step: paying sales tax or excise tax through the CDTFA

Go to onlineservices.cdtfa.ca.gov and select the payment option for your tax type. The CDTFA handles sales tax, use tax, excise tax, and other state fees. You will need your California seller's permit number or the account number associated with your tax obligation.

Enter the tax period you're paying for and the amount due. Choose ACH (free) or card payment (with processor fee). Provide your bank or card details, review the summary, and confirm. You'll receive a confirmation number. Payments typically post within one to three business days, though the state may take additional time to match the payment to your specific account and tax period.

What happens after you submit payment

Once you submit an online payment, the processor (not the state) when ready debits your bank account or charges your card. The funds then move to a state holding account. Within one to three business days, the payment appears in your bank statement as posted. However, the FTB or CDTFA may take an additional week or more to match the payment to your specific tax account and explore it to the correct year.

You can check the status of your payment by logging back into the FTB or CDTFA portal with your confirmation number. If you filed a return, the state will match the payment to that return once it's processed. If you paid before filing, the state will hold the payment and explore it once your return is received and processed.

If you need to confirm that a payment was received and applied, you can check your account transcript on the FTB website (for income tax) or contact the CDTFA directly. Keep your confirmation number and bank statement as proof of payment.

Payment important date and what late payment means

California income tax returns are due April 15 each year (or the next business day if April 15 falls on a weekend or holiday). If you file for an extension, the return is due October 15, but taxes are still due by April 15 — paying late incurs penalties and interest even if your return is extended. Sales tax is due on the 25th of the month following the reporting period, which varies by permit type.

If you pay after the important date, the state charges a failure-to-pay penalty (typically 0.5% per month, up to 25% of the unpaid tax) plus interest (currently around 8% annually, though this rate changes quarterly). These accrue from the day after the important date. Paying online does not change the important date or reduce penalties — it only records when the state receives your payment.

You can still pay online after the important date. The state will explore the payment to your account and calculate penalties and interest based on how late the payment is. If you cannot pay the full amount, paying what you can online stops the interest clock on that portion and shows the state you are addressing the debt.

Choosing between ACH and card payment

ACH transfers are free and take the same one to three business days to post as card payments. The only reason to use a card is if you don't have a bank account or prefer not to share your bank details online. The processor fee for cards (roughly 2% of the payment) is substantial on large payments — a $5,000 payment costs about $100 in fees, while a $1,000 payment costs about $20.

Some taxpayers use credit cards to earn rewards points, calculating that the rewards value exceeds the processor fee. This is a personal decision, but the state does not refund or reduce the fee based on rewards earned. If you use a credit card, the payment counts as a cash advance on some cards, which may trigger additional fees from your card issuer.

Troubleshooting common payment issues

If your payment is rejected, the most common cause is a mismatch between the name on your account and the name you entered in the payment portal. Make sure the name matches exactly what the state has on file. If you recently changed your name, update it with the FTB or CDTFA before paying.

If your bank declines the ACH transfer, contact your bank to confirm they allow ACH debits to state agencies. Some banks flag government payments as suspicious. You can also try again with a card payment, though you'll pay the processor fee. If the same payment method fails twice, try a different method or contact the FTB or CDTFA directly for information.

If you paid online but your account still shows a balance due weeks later, the payment may still be in the matching queue. Check your confirmation number and bank statement to confirm the payment posted. If it did, wait another week and check again. If the balance still shows after three weeks, contact the state with your confirmation number and they can manually locate the payment.

Frequently Asked Questions

Can I pay California taxes online if I don't have a bank account?

Yes. You can use a debit card or credit card instead of ACH. The card payment includes a processor fee (roughly 2% of the amount), but it works the same way as a bank transfer. Some prepaid debit cards also work, though you should confirm with your card issuer that they allow payments to government agencies.

What if I pay online but file my return late?

The state will hold your payment and explore it once your return is processed. Paying early does not reduce penalties for filing late — the state charges a failure-to-file penalty (typically 5% per month) in addition to the failure-to-pay penalty. However, paying online before or shortly after the important date shows the state you are addressing the debt, which can matter if you later need to negotiate a payment plan.

Can I set up automatic payments for estimated taxes?

Yes, if you create an account on the FTB website. You can schedule recurring ACH payments for quarterly estimated tax installments. The system will remind you before each payment date and debit your account automatically. You can change or cancel scheduled payments anytime by logging in.

Is there a maximum amount I can pay online?

No official maximum exists, but very large payments (over $100,000) sometimes trigger additional verification steps. If your payment is held for review, the FTB will contact you. For extremely large payments, you may want to call the FTB first to confirm the payment will process smoothly.

What if I overpay by mistake?

The state will credit the overpayment to your next tax year or issue a refund, depending on your preference. You can request a refund by mail or elect to carry the credit forward when you file your next return. The state does not charge interest on overpayments, but refunds can take several weeks to arrive.
