An assessment or a claim for credit must be made within five calendar years after the annual tax filing is made. For a five-year period preceding the current calendar year, a company may apply for a credit, or the commissioner may make an assessment, as appropriate. The period of examination and determination of the correct amount of tax is unlimited in the case of a false or fraudulent return made with the intent to evade tax or in the case of a failure to file a return.1998 Acts, ch 1057, §1Referred to in 432.1B
