Ark. Code Ann. § 26-65-101 et seq.

(k) “Substantially Similar Tax” means a tax that is levied on the aggregate taxable income of each of the persons that have an ownership interest in an entity that is engaged in business for profit. The Department will annually publish a non-exhaustive list of states that have enacted a substantially similar tax on its website prior to February 1 of each year. The final such list will be published in February 2026 unless the Secretary, in his or her sole discretion, decides to publish the list in one or more subsequent years. Any changes in law that affect the levy, collection, implementation, administration, remittance, or calculation of a substantially similar tax could result in that tax being treated as not substantially similar, regardless of its inclusion in the annual list of substantially similar taxes. The fact that a tax is not included on the annual list is not conclusive to the determination of whether the tax is a substantially similar tax.

(l) “Taxable year” means the calendar year, or the fiscal year ending during such calendar year, upon the basis of which taxable income is computed.
