N-30: Corporation Income Tax Return (2024)
Hawaii · Hawaii DoTax · Used for tax years 2024
Form N-30 is Hawaii’s Corporation Income Tax Return for 2024. It reports corporate income, deductions, Hawaii tax adjustments, credits, and payments to calculate tax due or an overpayment.
What you'll need
Have your federal return available. Form N-30 directs you to use amounts from comparable federal return lines for lines 1–5 and 7–10, and the business activity code from federal Form 1120 or 1120A.
Depending on what you report, the form calls for these attachments:
- Capital gains or other gains and losses: Hawaii Schedule D for line 6(a) and Hawaii Schedule D-1 for line 6(b).
- Extension payments: Form N-201V for line 16(c).
- Amended return: Schedule AMD.
- Consolidated return: Copies of Hawaii Forms N-303 and N-304 for each subsidiary.
- Hawaii income adjustments: Supporting schedules for Schedule J, lines 2(b), 2(d), 9, and 10, and an explanation for casualty-loss amortization on line 8.
- Look-back interest on completed long-term contracts: Federal Form 8697 for Schedule J, line 24.
Schedule CR supplies the credit totals reported on lines 12 and 14.
Common mistakes
- Missing the farming-loss election statement: If the corporation has a farming net operating loss for the tax year and elects to forgo the carryback period, the form says to attach a statement making that election.
- Treating preparer discussion permission as Form N-848: The form explicitly says that allowing the Department of Taxation to discuss the return with the listed preparer does not replace Form N-848.
- Skipping the instructions when line 13 is zero or less: The form specifically directs you to consult the instructions in that situation.
