The Delaware Income Tax Office is not open for in-person assistance but our tax staff is still ready to help with the following contact-free services.

Drop-off by March 15. This is a free service. If you would like our office to prepare your return for you:

  1. Sign your 2020 City of Delaware Income Tax form and provide both your email address and telephone number. Please note if you have moved in or out of Delaware during 2020, the date, and your current address if different from the one printed on the form.
  2. Place your form in the enclosed envelope along with your tax documents (W2 forms, federal schedules, etc.).
  3. Drop the envelope off at either City Hall or Mingo Park. There are red drop-boxes located outside both buildings. Our tax specialists will contact you if there are any questions. Once your return is completed a copy will be mailed to you for your records, along with a letter detailing the balance due, if any.
    Please note that if utilizing this service, you must drop off by March 15.  After this date we cannot guarantee your return will be completed in time to determine your tax liability.  All tax due is due by April 15. Tax paid after this date is subject to penalty and interest.  If mailing instead of dropping off, envelope must be postmarked by March 15.

Use our e-file/e-pay tool to quickly and easily file your return or make a payment by checking account or credit card (no fee).  You will need your five-digit Delaware tax ID.  If you have questions or need assistance call 740-203-1225, Monday through Friday from 8 am to 5 pm.

Phone 740-203-1225 to have a tax specialist help you complete your return by phone, Monday through Friday from 8 am to 5 pm.

The City of Delaware income tax office oversees the administration of a City income tax, including filing and payment. In accordance with Chapter 192 of Delaware’s codified ordinance, the City imposes a 1.85-percent tax on income earned by resident individuals and resident businesses; and non-resident individuals and non-resident businesses earning income in the City.  Tax office hours are Monday through Friday from 8 am to 5 pm. Email the office or phone 740-203-1225.


If none of the above service options fit your needs, appointments are available from 8 am until 10 am each business day for 30-minute increments. Appointments are for matters that can ONLY be addressed in person. Appointments for accepting payments are discouraged as customers can pay online, over the phone or use a drop box. You will receive confirmation via email or text message, and a reminder closer to the date of the appointment. Upon arrival at Mingo Park, phone 740-203-1000. Customers are required to wear masks while inside the building. Click Here to Book your in-person tax meeting.
