What is FIDM?

The Financial Institution Data Match (FIDM) Program was created from federal legislation passed in 1996. FIDM requires state child support agencies to enter into agreements with financial institutions to identify accounts of child support debtors through a match process. FTB is responsible for managing the FIDM Program in California, and we conduct quarterly matches with hundreds of single-state financial institutions operating in the state. We may issue liens or levies against those accounts to collect past-due child support.

Which financial institutions are subject to participation in the match process?

A financial institution for FIDM purposes is defined as any of the following:

  • Depository institution.
  • Institution-affiliated party.
  • Federal or state credit union (including an institution-affiliated party of a credit union).
  • Benefit association, insurance company, safety deposit company, or money market mutual fund.
  • Any other similar entity authorized to do business in the state.

What types of accounts are included in the match process?

An account for FIDM purposes means any:

  • Demand deposit account.
  • Share or share draft account.
  • Checking or negotiable withdrawal order account.
  • Savings account.
  • Time deposit account.
  • Money market mutual fund account, whether or not the account bears interest.

Does the data match law protect a financial institution from liability if it fully complies with the requirements?

If a financial institution fully complies with the requirements, it is protected from liability when it performs the following functions:

  • Discloses information to FTB.
  • Encumbers or surrenders any assets held by such financial institution in response to a notice of lien or levy (including an Order to Withhold) issued by FTB.
  • Any other action taken in good faith to comply with the data match requirements.
