I am on disability with OPERS. I have never paid state tax when I had a tax person do my taxes what changed

There are a number of reasons why your refund amount may change from one year to the next. Some of the most common reasons are because you earned more income this year, you did not withhold enough taxes from your pay or you did not make enough estimated tax payments, or your deductions and credits were reduced this year. 

For more information, please review, "Why did my refund go down compared to last year's?".
