Welcome and thank you for giving me the opportunity to assist you with your tax question.
Unfortunately, the Ohio tax assessment and collection process is overwhelming and not easy to understand by the taxpayer. Since Ohio has already filed a tax lien against you, my advice would be to either offer a settlement amount and/or contact the Ohio Problem Resolution Office at Ohio Department of Taxation, Problem Resolution Office, P. O. Box 530, Columbus, Ohio 43215.
My point of reference is the following: http://www.cincinnatitaxlawyer.com/areas-of-tax-practice/ohio-tax-problems.html.
From everything I have read, you will have a difficult task ahead of you, and I wish you the best of luck.
Please let me know if you need further information or clarification. Thank you.
