Assistance for Flood Victims

Dear Business Owner,

My agency is committed to helping businesses impacted by the devastating storm and flooding in Ellicott City, Catonsville, and Oella in May. As you may have heard, I issued a six-month extension for business returns due from impacted businesses; including sales and use tax, withholding tax, and admissions and amusement tax. Additionally, I am temporarily waiving international fuel tax agreement (IFTA) requirements for those providing emergency supplies and support to impacted areas.

If you have any questions or if we can help, please email Flood Support or contact my agency ombudsman at 410-260-4020 or

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.

Sales and Use Tax

Sales and Use Tax Form 202 - Sellers of prepaid wireless telecommunications services are required to report and remit all Prepaid Wireless E 9-1-1 Fees collected by the seller for retail transactions of prepaid wireless telecommunications.
