Haw. Code R. § 18-231-19.5-01
As used in sections 18-231-19.5-01 to 18-231-19.5-14:
"Audit or examination of a tax return" means all activities undertaken by the department in order to determine either (1) the correctness of the tax liability shown in any person's tax return, or (2) whether any person failed to file any tax return.
"Collection activities" mean all activities undertaken by the department, or by any collection agency described in section 231-13, HRS, to enforce the payment of any person's tax liability.
"Communication in connection with collection activities" means all communication undertaken by the department of this nature, including any inquiry into the financial resources of any person liable for tax; any levy, lien, garnishment, or seizure of any taxpayer's property; any certificate of discharge of a levy, lien, garnishment, or seizure of any taxpayer's property; and any certification of the absence of delinquent tax liability, including a tax clearance or a bulk sale certificate. A communication in connection with collection activities may be to any person and need not relate to the tax return of the person to whom the communication is addressed. A communication in connection with collection activities does not constitute a written opinion for purposes of section 231-19.5, HRS.
Example: T purchased all of the assets of B, a corporation. The department sends a letter to T proposing to collect B's delinquent tax liability from T because the general lien in favor of the State under section 231-33, HRS, attached to the assets. The letter is a communication in connection with collection activities.
"Communication in connection with the audit or examination of a tax return" means all communication undertaken by the department of this nature, including any subpoena or request for production of books and records under section 231-7, HRS; any assessment of any tax; any notice of proposed assessment of any tax; and any determination of jeopardy under section 231-24(a), HRS. A communication in connection with the audit or examination of a tax return may be to any person and need not relate to the tax return of the person to whom the communication is addressed. A communication in connection with the audit or examination of a tax return does not constitute a written opinion for purposes of section 231-19.5, HRS.
Example: H and W divorced in 1989. H filed a separate tax return for the calendar year 1989. The department sends a letter to H asking about a tax return W filed for calendar year 1989 because W claims that it is a joint tax return. Although the letter does not propose or suggest any adjustment to H's tax liability, the letter is a communication in connection with the audit or examination of a tax return.

"Determination letter" means a written statement issued by the department that applies a well-established interpretation or principle of tax law to a specific set of facts.
