California — Franchise Tax Board

FTB 4601

Demand for Tax Return — no California return on record

What this notice is

A Demand for Tax Return (FTB 4601) means the Franchise Tax Board has no record of your California personal income tax return for the year named. It is a filing question, not a bill — the FTB is asking you either to file or to explain, and it encloses a Reply to FTB form for saying you already filed, you do not have to file, or you are not sure. A business-entity version of the same demand exists as FTB 4684/4685.

What the Franchise Tax Board is generally saying

“We can’t find a California return under your number for this year. File it, or use the enclosed Reply to FTB form to tell us you already filed or don’t need to — within 30 days. If we hear nothing, we will estimate your income ourselves and propose tax with penalties added.”

Does this type carry a deadline?Typical window: 30 days from the date on the notice

If nothing arrives by the date on the notice, the FTB estimates your income and issues a Notice of Proposed Assessment that includes the estimated tax, a demand penalty, a delinquent filing penalty, and a cost recovery fee.

What people usually gather
  • The notice and its Reply to FTB form, every page
  • A copy of the California return for that year, if one was filed
  • Records that show whether a California filing requirement existed — residency dates, income sources, W-2s and 1099s
  • Any FTB letters that came before this one
What a licensed professional handles
  • Determining whether a California filing requirement actually exists for the year
  • Preparing and filing the missing return before the FTB estimates for you
  • Responding on the Reply to FTB form with substantiation
  • Heading off the proposed assessment before the stacked penalties attach
