(1) A taxpayer is treated as having disposed of, during the taxable year, any investment credit property which the taxpayer cannot establish was still on hand, in this state, at the end of that year.
(2) If a taxpayer cannot establish when investment credit property reported for purposes of claiming this credit returned during the taxable year was placed in service, the taxpayer is treated as having placed it in service in the most recent prior year in which similar property was placed in service, unless the taxpayer can establish that the property placed in service in the most recent year is still on hand. In that event, the taxpayer will be treated as having placed the returned property in service in the next most recent year.
