La. R.S. 47:1607 — Interest on erroneous refunds

The secretary shall remove interest which has accrued on an erroneous refund which has accrued up to the date the taxpayer is requested to repay a refund issued in error if the taxpayer did not cause the erroneous refund in any way and the refund does not exceed fifty thousand dollars. The secretary may remove or reduce interest on all other erroneous refunds or on refunds issued in error due to a ministerial act of the department, based on the facts and circumstances of each case. If the interest that was reduced or removed was reported as a deduction on the tax return of the taxpayer, the taxpayer must report the reduction or removal of interest as income on his tax return for the year the interest was reduced or removed.
