I am not sure why your tax professional said you didn't have to pay Indiana income taxes in 2015. I would suggest that you call him and ask him to explain the reason to you.
Part-year Indiana residents must file an Indiana individual income tax return (Form IT-40PNR). They are subject to tax on that part of their total federal income that was received while they were residents of Indiana. In addition, they are also taxable on income from Indiana sources received while they were nonresidents of Indiana.
Five states have a reciprocal agreement with the state of Indiana. They are Kentucky, Michigan, Ohio, Pennsylvania, and Wisconsin. All salaries, wages, tips, and commissions earned in these states by an Indiana resident must be reported as if they were earned in Indiana. A credit cannot be taken for any taxes withheld by or paid to any of these states in connection with income from salaries, wages, tips, and commissions. If taxes have been withheld or paid to any of these states, a claim for refund should be filed with that state by filing that particular state’s income tax form for nonresidents.
