(3) In the case of refunds made to recover taxes illegally collected on bonus payments from oil and gas leases located on tax exempt Indian lands interest at six percent (6%) per annum will be calculated from the date of payment by the taxpayer, until the date the refund is issued. [See: 68 O.S. § 2373]
