Business Withholding Responsibilities

Employers are responsible to ensure that tax returns are filed and deposits and payments are made, even if the employer contracts with a third party to perform these acts. The employer remains responsible if the third party fails to perform any required action. If the third party fails to make the tax payments, the Comptroller may assess penalties and interest on the employer’s account. The employer is liable for all taxes, penalties and interest due. The employer may also be held personally liable for certain unpaid taxes. To verify that the appropriate returns have been filed and payments have been made, you may contact the Comptroller’s Office at 410-260-7980 from Central Maryland or 1-800-MD TAXES from elsewhere.
