Hawaii filing notes
The standard deduction ($8,000 single for 2026) is still below the federal amount, so itemizing can pay off. The GET applies more broadly than most sales taxes. Hawaii offers a refundable food/excise tax credit. Take advantage of the very low property taxes.
Common mistakes: Not filing insurance claim first; Including losses outside disaster area.
