    • Q1. What is a deficiency (DF)?
      A taxpayer receives a deficiency status (DF) when there is an unpaid balance on the return. For example, if a taxpayer has $1,000.00 due per the tax return filed and only $900.00 is paid, then a deficiency amount for $100.00 remains. When this happens, a hold is placed on the taxpayer's account preventing them from renewing their Chicago business license. The Chicago Department of Finance then sends a notice out to the taxpayer informing them of the deficiency. Once the taxpayer pays what is owed including any applicable penalty and interest, the hold is removed.

    • Q2. What is a delinquency (DL)?
      A taxpayer obtains a delinquency status (DL) when they fail to file a tax return for any given period. When this happens, a hold is placed on the taxpayer's account preventing them from renewing their Chicago business license. The Chicago Department of Finance then sends a notice out to the taxpayer informing them of the delinquency. Once the taxpayer files the return and pays any applicable tax, interest, and penalty, the hold is removed.

      There are also specific delinquencies that a taxpayer can have:

      Delinquency Incomplete status (DI) = this happens when the taxpayer submits a tax return but some of the required information is missing. For example, if a taxpayer files the tax return but fails to include the annualization schedule, then the taxpayer would have a DI noted on their account. The Department will place a hold on the account preventing the taxpayer from renewing their business license. A notice is then sent to the taxpayer informing them of the hold. The hold remains until the taxpayer addresses the situation and submits the missing information and makes any required payments.

      Delinquency Unsigned status (DU) = this happens when a taxpayer submits a return but fails to sign the signature page. The Department places a hold on the taxpayer's account and sends a notice informing the taxpayer they have 30 days to provide the missing signature and pay any applicable tax, interest, and penalty.
