Key filing season resources:

  • Electronic filing options — Ohio offers several ways to cut to the front of the line and get your refund fast. More than 80% of Ohioans already file electronically. Why wait weeks for a refund when you can have it in days?
  • Income taxes and the military — Complying with income tax laws can be tricky for members of the military and their families.
  • Your 1099 Documents Available Electronically in Ohio Online Services — To streamline operations and reduce costs, your 1099 documents are now available in the Ohio Income Tax Online Services system. Simply go into the Ohio Online Services link above and register to file your 2018 Income Tax or School District Income Tax return. Once you register in Online Services, log in and click on the View Ohio 1099s option. Read all of the information before you view your document. Questions regarding the 1099s can be answered in our expanded FAQ's. We encourage you to print and retain these important documents for your records.
