FTB 4963: California's bill for a balance due
A Notice of State Income Tax Due means the FTB says you have a past due balance on your personal income taxes. Unlike the NPA stage, the assessment behind this bill is generally final, so the choices now are about payment: pay it, set up an installment agreement, pursue an Offer in Compromise or hardship relief, or dispute with documentation if the balance is factually wrong, for example a payment that never posted.

Where you are in California's collection sequence
What the notice contains
The FTB describes two parts: a payment voucher for mailing payment, and an account balance summary with the specifics of what it says you owe. If you agree with the amount, the FTB's instruction is simply to pay it; no contact is needed.
If you disagree, gather the notice, relevant tax documents, and proof of payment, and contact the FTB or upload documents through MyFTB. Posting errors and crossed payments are the classic fixable cases at this stage.
Why not to sit on it
What the FTB says comes next
The FTB's collections publication is unusually direct: failure to contact them and resolve the balance can lead to wage garnishment, a recorded lien against your property, seizure of property, and bank levies. California can also intercept state and federal payments owed to you, including through the federal Treasury Offset Program, and tack on a collection cost recovery fee. The escalation letters that follow this bill are the Final Notice Before Levy and then the orders themselves.
The realistic paths
Pay it
Online, by mail with the voucher, or through MyFTB. Interest stops when the balance reaches zero.
Monthly payments
The FTB installment agreement is available online for balances up to $25,000 payable within 60 months, with all returns filed for the past 5 years. Setup costs $34, approval can take up to 90 days, and a tax lien may be a condition of the arrangement.
What happens if you wait instead →Genuine hardship
California has its own lump-sum-only Offer in Compromise and a one-time 30 day payment delay. There is no formal FTB equivalent of the IRS currently-not-collectible program, so hardship is argued case by case.
FTB 4963 questions
Can I still dispute the tax at this stage?
The underlying assessment is generally final by the time a 4963 arrives; the protest window belonged to the Notice of Proposed Assessment. What remains disputable is factual accuracy, payments not credited, identity issues, amounts already paid. Beyond that, the remaining route is paying in full and filing a claim for refund.
How long does California have to collect this?
Twenty years under R&TC 19255, double the IRS's ten, and the clock runs from the latest liability on the account, so a later penalty or fee assessment can reset it. Waiting California out is rarely a strategy; the state also holds levy, lien, garnishment, and interception tools the whole time.
Does an FTB payment plan stop collection?
An approved installment agreement generally keeps involuntary collection paused while you keep its terms. Two FTB specifics: approval can take up to 90 days, and a tax lien may be a condition of the arrangement. If a wage garnishment or bank levy is already in place, you cannot apply online and must call instead.
