Section 56 - Interest on delayed refunds.

Interest on delayed tax refunds after 60 days: up to 6% normally, up to 9% for final-order claims

If a tax refund under the statutory refund provision is not paid within sixty days of receipt of the refund application, interest is payable for the delay beyond sixty days until payment, at a rate not exceeding six percent as notified and computed subject to prescribed manner and conditions. Where the refund claim arises from a final order of an adjudicating, appellate, tribunal or court, a higher interest rate up to nine percent may be notified and applies from the day after the sixty-day period until refund. Appellate or court orders correcting a prior officer's denial are treated as orders under the refund provision.
