Penalties and Interest

1. Interest Underpayment or late payment

   The Delaware Code provides that interest on any underpayment or late payment of income taxes due shall accrue at the rate of 1% per month, from the date prescribed for payments to the date paid.

2. Penalty Late-filing of balance due return

   The law imposes substantial penalties for failure to file a timely return. Late-filed returns with a balance due are subject to a penalty of 5% per month up to a maximum of 50% of the balance due.

3. Penalty Negligence/fraud/substantial understatement

   The law also provides severe penalties for a false or fraudulent return, or for a false certification. The mere fact that the figures you report on your Delaware return are taken from your Federal return will not relieve you from the imposition of penalties for negligence or for filing a false or fraudulent return.

4. Penalty Failure to pay

   The law provides a penalty of 1/2% per month (not to exceed 25%) of the net tax liabilities for failure to pay the tax liability due on a timely filed or late-filed return. This penalty is in addition to the interest charged for late payment.

5. Penalty Failure to File/Pay Estimated Taxes

   The law provides a penalty of 1 1/2% per month of the computed tax payment for failure to file/pay estimated taxes due. This penalty is in addition to those penalties and interest listed above. The penalty is also assessed if the estimated payment is filed late.
