Can delinquency and deficiency interest be imposed simultaneously?

Can delinquency and deficiency interest be imposed simultaneously?

• A. Yes
• B. It is possible
• C. No
• D. Only for some taxpayers

Answer: (C)

Two separate interest charges exist for underpayments: delinquency interest and deficiency interest. Delinquency interest accrues when tax is not paid by the due date, on the amount still unpaid. Deficiency interest accrues on the deficiency amount determined after an examination, from the original due date to payment. For the same tax liability, only one type applies—they are not imposed at the same time. If there’s a deficiency, deficiency interest governs that amount; if no deficiency is determined, delinquency interest applies to any late payment. Because they’re triggered by different situations, they can’t be imposed simultaneously on the same underpayment.
