Haw. Rev. Stat. § 431:7-206
If by the laws of any state other than this State, or by the action of any public official of another state, any insurer or company, as defined in section 431:1-202, organized or domiciled in this State, shall be required to pay taxes for the privilege of doing business in the other state, and the amounts are imposed or assessed so that the taxes which are or would be imposed against Hawaii domestic insurance companies are greater than those taxes required of insurers organized or domiciled in the other state, to the extent the amounts are legally due to the other states, an insurer or company organized or domiciled in this State may claim a credit against the tax payable pursuant to this article of a sum not to exceed one hundred per cent of the amount. The credit shall not be greater than the tax payable pursuant to this article during the taxable year. All claims for the tax credit under this section, including any amended claims, shall be filed on or before the end of the twelfth month following the close of the taxable year for which the credit may be claimed. Failure to comply with the foregoing provision shall constitute a waiver of the right to claim the credit.
