Haw. Rev. Stat. § 231-36.5
(b) A tax return preparer who:
(2) Recklessly disregards any tax law or rule in understating a person's tax liability,
based upon unreasonable positions on a tax return or claim for tax refund shall pay a penalty of $1,000, with respect to each such tax return or claim for tax refund.
(c) For purposes of subsections (a) and (b), understatements of liability using unreasonable positions occur when:
(d) If within thirty days after the notice and demand of any penalty under subsection (a) or (b) is made, the tax return preparer:
(2) Files a claim for refund of the amount so paid,
no action to levy or file a proceeding in court to collect the remainder of the penalty shall be commenced except in accordance with subsection (e).
(e) An action that is stayed pursuant to subsection (d) may be brought thirty days after either of the following events, whichever occurs first:
(2) The tax return preparer fails to file an appeal to the tax appeal court for the determination of the tax return preparer's liability for the penalty assessed under subsection (a) or (b) within six months after the day on which the claim for refund was filed.
Nothing in this subsection shall be construed to prohibit any counterclaim for the remainder of the penalty in any proceeding.
(g) At the request of the director of taxation, a civil action may be brought to enjoin a tax return preparer from further acting as a tax return preparer or from engaging in conduct prohibited under subsection (a) or (b) as follows:
(h) For purposes of this section:
"Disclosed item" means any item where:
(2) There is a reasonable basis for the tax treatment of the item by the taxpayer.
"Substantial authority" means, in addition to any definition of substantial authority incorporated by subsection (j), that the following authority supports the tax treatment of an item:
(8) Notices or other official pronouncements of the department of taxation.
"Tax return preparer" means any person who prepares for compensation, or who employs one or more persons to prepare for compensation, any return of tax imposed under title 14 or any claim for refund of tax imposed under title 14. For purposes of this definition, the preparation of a substantial portion of a return or claim for refund shall be treated as if it were the preparation of the return or claim for refund.
A person shall not be a tax return preparer merely because the person:
(4) Prepares a claim for refund for a taxpayer in response to any notice of deficiency issued to the taxpayer or in response to any waiver of restriction after the commencement of an audit of the taxpayer, or of another taxpayer if a determination in the audit of the other taxpayer directly or indirectly affects the tax liability of the taxpayer.
"Understatement of liability" shall have the same meaning as stated in section 231-36.6(b). The determination of whether there is an understatement of liability may be made without regard to any administrative or judicial action involving the taxpayer.
