The director of revenue shall prescribe regulations dealing with situations in which the application of sections 143.011 to 143.996 to a taxpayer produces a computation of taxable income under a method of accounting different from the method under which the taxpayer’s taxable income for the previous year was computed for Missouri income taxation. The regulations shall provide change of accounting method adjustments over a period not to exceed five years where the adjustments are necessary to prevent substantial amounts from being duplicated or omitted.
