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

What a Franchise Tax Board payment plan does

A Franchise Tax Board (FTB) payment plan lets you pay a California state tax debt over time instead of in one lump sum. The FTB is California's tax agency, and when you owe them money from unpaid income tax, they can set up an agreement where you make monthly payments until the balance is cleared. The plan does not erase what you owe—it just spreads the payments across months or years so the full amount becomes manageable.

You can request a payment plan whether you owe a small amount or several thousand dollars. The FTB has two main types: a short-term payment plan (usually paid off within 120 days) and a long-term installment agreement (longer than 120 days). Which one you get depends on how much you owe and how quickly you can pay.

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 FTB 668.
• Short-term plans typically require payment within 120 days with no setup fee; long-term plans may charge a fee and require a monthly commitment.
• The FTB will continue to charge interest and penalties on your unpaid balance while you make payments, so paying faster reduces what you ultimately owe.
• If you miss a payment or your financial situation changes, contact the FTB immediately to modify or avoid default on your plan.
• A payment plan does not stop wage garnishment or bank levies that may already be in progress—you may need to request a separate halt.

How to request a payment plan

The fastest way to set up a plan is online through the FTB's website at ftb.ca.gov. Log into your account, find your tax debt, and look for the payment plan option. The online tool walks you through the process and can approve a short-term plan immediately. You will need your Social Security number, the tax year in question, and information about your current income and expenses.

If you prefer not to use the website, you can call the FTB at 1-800-338-0505 during business hours. A representative can discuss your situation and set up a plan over the phone. For a long-term installment agreement, you may need to submit Form FTB 668 (Installment Agreement Request) by mail along with financial information showing why you cannot pay the full amount right away.

Mail requests take longer to process—usually two to four weeks—so call or use the online option if you need a faster response. The FTB will send you a confirmation letter once your plan is approved, showing your monthly payment amount and due date.

What happens to interest and penalties while you pay

Interest and penalties continue to accrue on your unpaid balance every month you are on a payment plan. California charges interest at a rate set quarterly (it varies but is typically around 5 to 8 percent annually). You also may owe a failure-to-pay penalty of 0.5 percent per month on the unpaid amount. This means the longer your plan runs, the more total interest you will pay.

For example, if you owe $5,000 and set up a 24-month plan, you will pay significantly more than $5,000 by the end because interest keeps adding to the balance. If you can pay faster—by making larger payments or paying off the plan early—you will reduce the total interest charged. There is no penalty for paying off a plan early, so if your financial situation improves, you can accelerate payments without extra cost.

Fees and costs for different plan types

Short-term payment plans (120 days or less) typically have no setup fee. You simply agree to pay the full amount within that window, and the FTB monitors your payments.

Long-term installment agreements may include a setup fee, which varies depending on how you apply. Online applications for long-term plans usually have a lower fee than phone or mail requests. The FTB will disclose the exact fee before you agree to the plan. In addition to the setup fee, you pay interest and penalties on the unpaid balance each month, as described above.

If you are low-income, you may be able to request a fee waiver or reduction. Ask the FTB representative when you apply whether you may have access to based on your income and expenses.

What happens if you miss a payment

Missing even one payment can put your plan in default. When that happens, the FTB may cancel the agreement and pursue collection actions like wage garnishment, bank levies, or property liens. The sooner you contact them after a missed payment, the better your chances of getting back on track without losing the plan.

If you know a payment will be late, call the FTB before the due date and explain your situation. They may grant a short extension or adjust your payment schedule. If you have already missed a payment, contact them immediately to ask about reinstatement. Bring documentation of your hardship (job loss, medical emergency, etc.) if you have it—the FTB is more likely to work with you if they understand what happened.

If your financial situation has changed and you can no longer afford the monthly amount, you can request a modification to the plan. The FTB will review your current income and expenses and may lower your payment or extend the timeline.

Payment plan does not stop existing collection actions

If the FTB has already started wage garnishment or a bank levy before you set up a payment plan, the plan does not automatically stop those actions. You need to request a separate halt, usually by submitting a Request for Release of Levy or contacting the FTB's collection department directly.

When you call to set up a payment plan, mention any active garnishments or levies. The FTB may release them once your plan is approved and you make your first payment on time. However, this is not may provide—it depends on the amount owed and the FTB's assessment of your ability to stick to the plan. Getting the plan in writing and making that first payment promptly gives you the strongest position to request a release.

Alternatives if a payment plan does not work

If you cannot afford even a long-term payment plan, you have other options. A Currently Not Collectible (CNC) status temporarily pauses collection efforts while you are in financial hardship. The debt does not go away, but the FTB stops garnishing wages or levying bank accounts. You must reapply periodically to maintain CNC status, and interest continues to accrue.

You can also explore an Offer in Compromise, which allows you to settle the debt for less than the full amount owed. This is harder to obtain and requires detailed financial documentation, but it may be worth exploring if your circumstances are severe. Contact the FTB or a tax professional to discuss whether you might may have access to.

Frequently Asked Questions

Can I set up a payment plan if I owe penalties and interest, not just the original tax?

Yes. The payment plan covers the original tax amount plus all penalties and interest that have accrued. The FTB will calculate the total and base your monthly payment on that amount. Interest continues to accrue on the unpaid balance during the plan, so paying faster reduces the total you owe.

What if I cannot afford the monthly payment the FTB offers?

Contact the FTB and request a modification. Bring documentation of your income, expenses, and any hardship. They may lower the payment amount or extend the plan timeline. If you still cannot pay, ask about Currently Not Collectible status, which pauses collection while you are in financial hardship.

Do I have to make payments by a certain date each month?

Yes. Your payment plan will specify a due date each month. Payments must be received by that date to stay in good standing. You can pay online, by phone, by mail, or through automatic bank transfer (ACH). Setting up automatic payments reduces the risk of missing a due date.

Can I pay off my plan early without a penalty?

Yes. There is no penalty for paying off a payment plan early. In fact, paying faster reduces the total interest you will owe. If you come into extra money, you can make a larger payment or pay the balance in full without any additional cost.

Will a payment plan affect my credit score?

A payment plan itself does not appear on your credit report. However, the original unpaid tax debt may have already been reported to credit bureaus. Once you set up a plan and make payments on time, your credit may gradually improve, but the past delinquency will remain on your report for a period of time.
