How to Set Up a Payment Plan With California's Tax Franchise Board

What a California tax payment plan does

If you owe California income tax and cannot pay the full amount by the deadline, the Franchise Tax Board (FTB) will let you spread the payment across months instead of facing a lump-sum demand. A payment plan is an agreement between you and the FTB: you commit to paying a set amount on set dates, and the FTB agrees not to pursue collection action while you are current on those payments. You still owe interest and penalties on the unpaid balance, but the plan stops the meter on additional collection costs and gives you breathing room to pay without losing your bank account or paycheck to garnishment.

The FTB offers two types of plans. A short-term plan lets you pay within 120 days with no setup fee. A long-term installment agreement spreads payments over months or years and requires a one-time fee, currently between $30 and $225 depending on how you set it up. Both plans require you to stay current on future tax returns—if you miss a payment or file late, the FTB can cancel the plan and resume collection.

Key Takeaways

• You can request a payment plan online through the FTB website, by phone at 1-800-338-0505, or by mail using Form 668-D; online is fastest and requires no fee for setup.
• Short-term plans (120 days or less) cost nothing to set up, but long-term plans charge a fee of $30 to $225 depending on whether you pay by direct debit or check.
• The FTB will calculate your monthly payment based on what you owe and how long you want to pay, but you can request a lower amount if that payment would cause hardship.
• Missing even one payment can cancel your plan and trigger collection action, so set up automatic payments if possible to avoid missed deadlines.
• Interest and penalties continue to accrue on the unpaid balance, so paying faster saves you money even if you are on a plan.

How to request a payment plan online or by phone

The fastest way to set up a plan is through the FTB website at onlineservices.ftb.ca.gov. You will need your Social Security number, date of birth, and the tax year(s) you owe for. Log in or create an account, then select "Set Up a Payment Plan" from the menu. The system will show you what you owe, let you choose how many months to pay, and calculate the monthly amount. You can accept the plan immediately, and it takes effect the same day. There is no fee for setting up online.

If you prefer to call, the FTB phone line is 1-800-338-0505. Have your Social Security number, tax return, and a calculator ready. A representative will discuss your situation, calculate payment options, and set up the plan over the phone. This route takes longer than online but lets you ask questions and request a lower payment if the calculated amount is too high.

You can also mail Form 668-D (Installment Agreement Request) to the FTB address listed on your notice. Mail is the slowest option—allow two to three weeks for processing—but it works if you do not have internet access or prefer a paper trail.

What happens to interest and penalties while you pay

Interest accrues daily on the unpaid balance at a rate set by California law, currently around 0.5% per month (roughly 6% per year), though this rate changes quarterly. Penalties also remain on your account: the failure-to-pay penalty is typically 0.5% of the unpaid tax per month, up to 25% of the original tax owed. Neither interest nor penalties stop while you are on a payment plan—they only stop accruing once you pay the balance in full.

This means a long-term plan costs more than a short-term one because interest and penalties have more time to grow. If you owe $5,000 and pay it off in 12 months, you will pay less in interest than if you spread it over 36 months. However, a payment plan still saves money compared to not paying at all, because the FTB will not add collection costs, bank levies, or wage garnishment fees on top of what you already owe.

Fees for different payment plan types

A short-term plan (120 days or fewer) has no setup fee. You simply agree to pay the full amount within that window, and the FTB processes it at no cost.

A long-term installment agreement charges a one-time fee based on how you pay. If you set up automatic payments from your bank account (direct debit), the fee is $30. If you pay by check, money order, or credit card, the fee is $225. The fee is added to your balance, so you will pay it as part of your monthly installments. Setting up direct debit is almost always cheaper and also reduces the risk of missing a payment.

How the FTB calculates your monthly payment

The FTB divides what you owe by the number of months you choose. If you owe $3,600 and request a 12-month plan, your payment is $300 per month (plus interest and penalties that accrue each month, which the FTB adds to future bills). The system suggests a payment based on standard terms, but you can request a different length if you need lower monthly payments.

If the calculated payment would cause hardship—meaning you cannot cover basic living expenses and the payment at the same time—you can request a lower amount. Call 1-800-338-0505 and explain your situation. The FTB has discretion to lower the payment or extend the timeline, though they will ask for proof of income and expenses. Requests for hardship relief are not automatic, but they are worth making if the standard payment is genuinely unaffordable.

What cancels a payment plan and what happens next

The FTB will cancel your plan if you miss a payment, file a tax return late, or do not pay a new tax bill on time. Once the plan is cancelled, the FTB resumes collection action: they can levy your bank account, garnish your wages, or place a lien on your property. You will receive a notice before cancellation, usually giving you 10 days to bring the account current.

If your plan is cancelled, you can request a new one, but the FTB may be less willing to work with you a second time. The best protection is to set up automatic payments so you never miss a due date. You can change your payment amount or timeline by calling the FTB, but you must do so before a payment is due—not after you have missed it.

What to do if you cannot afford the payment plan payment

If you are on a plan and a payment becomes unaffordable due to job loss, illness, or other hardship, contact the FTB immediately. Do not simply skip the payment—that will cancel the plan. Call 1-800-338-0505 and ask to modify your plan. Explain what changed in your situation and provide recent pay stubs, bank statements, or other proof of income. The FTB can lower your payment, extend your timeline, or in rare cases place your account in "currently not collectible" status, which pauses collection while you recover.

If you are struggling with basic needs, you may also be may be able to access for the California Earned Income Tax Credit (CalEITC) or other state tax credits that reduce what you owe in future years. The FTB website has a tool to check your may be able to access. Reducing future tax debt is often faster than trying to modify a current payment plan.

Frequently Asked Questions

Can I set up a payment plan if I have already received a wage garnishment notice?

Yes. Contact the FTB immediately and request a payment plan. Once the plan is approved, the FTB will typically stop the garnishment, though there may be a delay of a few days while the paperwork processes. Bring the garnishment notice when you call so the representative can prioritize your case.

What if I pay off my plan early?

You can pay the remaining balance at any time without penalty. Paying early stops interest from accruing on the unpaid portion, so it saves money. You do not need permission from the FTB—simply send a check or make an online payment for the full remaining amount.

Do I still have to file my tax return every year if I am on a payment plan?

Yes. Filing on time is a condition of your payment plan. If you file late or do not file at all, the FTB will cancel the plan. If you cannot file by the deadline, request an extension from the IRS (which also extends your California deadline) before the due date.

Can I have a payment plan for multiple tax years at once?

Yes. If you owe for 2021 and 2022, for example, the FTB can combine the amounts into a single plan with one monthly payment. This is simpler than managing separate plans and is usually the default when you request one.

What if my income changes and I can no longer afford the payment?

Call the FTB at 1-800-338-0505 and ask to modify your plan. Bring recent pay stubs or income documentation. The FTB can lower your payment or extend the timeline, though they will review your situation to make sure the new amount is reasonable.
