The corporate tax law addresses taxation based on the profits and income earned by corporations operating within D.C. Under the Corporate Income Tax (CIT) regulations, corporations are required to report their earnings and submit taxes accordingly.

 

Corporate entities include for-profit corporations such as stock corporations, limited liability companies (LLCs), partnerships, and foreign businesses that are registered to do business in the District.

  • Fiscal Year-end of December 31: Filing due by April 15th of the following year.

Failure to File Corporate Tax Returns: If a corporation fails to file within the designated time, penalties for non-filing apply, often including interest on unpaid taxes and a 20% penalty.

 

Underreporting or Misreporting of Income: If corporate income is underreported by over 25%, additional penalties apply, such as a 40% underreporting penalty on the unpaid taxes. In severe cases, charges for fraudulent tax evasion may lead to prosecution under the Tax Fraud Act.

 

Tax Evasion (Intentional Fraud): Deliberate attempts to evade taxes by falsifying returns or engaging in tax shelters may lead to criminal prosecution with penalties of up to $1,000,000 in fines or 10 years imprisonment.

Falsifying Corporate Tax Returns: In some cases, corporations have been found to falsify tax returns by inflating deductible expenses or misclassifying income to evade taxes. This leads to serious criminal penalties, including jail time for responsible corporate officers.
