2025 Tax Reform Context

Hawaii’s 2025 brackets reflect the most significant reform in the state’s history. Under Act 46, SLH 2024 (Green Affordability Plan II, signed June 2024), bracket thresholds were substantially widened starting January 1, 2025:

  • The 1.40% rate now applies to single-filer income up to $9,600 (up from $2,400 in 2024).
  • The 11.00% top rate now applies only to income exceeding $325,000 for single filers (up from $200,000 in 2024).
  • Bracket changes continue in phases through 2031.
  • Standard deduction was doubled from $2,200 to $4,400 (single) and $4,400 to $8,800 (MFJ) starting in Tax Year 2024.

Who Must File Hawaii Income Tax

Residents

Hawaii residents must file a state income tax return (Form N-11) if their gross income for the year exceeds the standard deduction plus total personal exemptions for their filing status. For Tax Year 2025:

  • Single: Standard deduction $4,400 + personal exemption $1,144 = minimum threshold ~$5,544
  • Married Filing Jointly: Standard deduction $8,800 + 2 exemptions ($2,288) = minimum threshold ~$11,088
  • Head of Household: Standard deduction $6,424 + personal exemption $1,144 = minimum threshold ~$7,568

Residents file on income from all sources, both inside and outside Hawaii.

Key rule: If you are required to file a federal return, you are also generally required to file a Hawaii return.

Part-Year Residents

Part-year residents must file Form N-15 if they had income from any source during the period of Hawaii residency, or Hawaii-source income during the period of non-residency.

Non-Residents

Non-residents file Form N-15 if they had any income from Hawaii sources during the tax year, including:

  • Wages earned while physically working in Hawaii
  • Business income from Hawaii operations
  • Rental income from Hawaii property
  • Gains on the sale of Hawaii real property
  • Hawaii partnership or S corporation distributive income

Note: In Hawaii, nonresidents must file if their income from Hawaii sources exceeds the state’s standard deduction. (Source: Tax Foundation analysis of HRS §235 filing requirements)

Hawaii’s Unique April 20 Deadline

Unlike most states that follow the federal April 15 deadline, Hawaii’s individual income tax return deadline is April 20, 2026 for Tax Year 2025 returns.

Automatic Extension:
An automatic 6-month extension to October 20, 2026 is granted — no form required — if either:

  1. The taxpayer is due a refund, OR
  2. The taxpayer pays the properly estimated tax amount owed by April 20, 2026

The extension applies only to filing, not to paying taxes owed. At least 90% of the final tax liability must be paid by April 20, 2026 to qualify.

What Income Is Taxable in Hawaii

Fully Taxable Income

The following income types are fully subject to Hawaii state income tax:

  • Wages and salaries
  • Tips and commissions
  • Self-employment income (net of business expenses)
  • Business income from sole proprietorships and pass-through entities
  • Investment income — interest, dividends, capital gains
  • Traditional IRA and 401(k) distributions (pre-tax portions)
  • Rental income from Hawaii and non-Hawaii property (for residents)
  • Alimony received (under agreements entered before 2019, following federal treatment)
  • Unemployment compensation
  • Gambling winnings

Social Security Benefits

Hawaii fully exempts Social Security benefits from state income tax.

Social Security benefits (and Railroad Retirement Act benefits) are excluded from Hawaii taxable income under HRS §235-7(a)(3). This exemption is complete — no income threshold applies and no portion of Social Security is taxable regardless of total income.

Military Retirement Pay

Hawaii fully exempts military retirement pay from state income tax.

Military retired pay (including disability retirement) is not subject to Hawaii income tax. Survivor Benefit Plan (SBP), Reserve Component Survivor Benefit Plan (RCSBP), and Retired Serviceman’s Family Protection Plan (RSFPP) annuities are also exempt.

Source: https://files.hawaii.gov/tax/legal/taxfacts/tf97-2.pdf

Pension Income

Hawaii applies an important distinction between employer-funded and employee-funded pension income:

Employer-funded pensions (fully exempt):
The employer-funded portion of a pension, annuity, or retirement benefit paid on account of retirement or disability is excluded from Hawaii taxable income under HRS §235-7(a)(3). This includes:

  • State and county government pensions
  • Federal government (FERS, CSRS) pensions — employer-funded portion
  • Private employer pension plans — employer-funded portion
  • Teachers’ pension funds

Employee-funded / elective deferrals (taxable):
Distributions from plans funded with pre-tax employee contributions — such as 401(k) plans and traditional IRAs — are generally taxable in Hawaii. The taxable portion is determined using an exclusion ratio under Hawaii Administrative Rules §18-235-7-03.

Key complexity: Many employer pension plans involve a mix of employer and employee contributions. A Schedule J (Form N-11) calculation is required to determine the excludable portion. Employees should retain their first-year Schedule J computation.

Retirement Account Distributions

Traditional 401(k) and Traditional IRA:
Pre-tax distributions are fully taxable as Hawaii ordinary income at progressive rates.

Roth IRA:
Qualified distributions from Roth IRAs are not subject to Hawaii income tax (following federal treatment).

Note on 401(k) employer-matching contributions:
If an employer made matching contributions to a 401(k) plan, that portion of distributions may qualify for the pension exclusion. An exclusion ratio calculation is required.

Reserve and National Guard Pay

Hawaii National Guard and Reserve component members may exclude up to $8,636 of military reserve or National Guard duty pay from Hawaii taxable income (Act 197, SLH 2004, codified in HRS Chapter 235).

Source: https://files.hawaii.gov/tax/forms/2024/n11ins.pdf

Income Specifically Excluded from Hawaii Taxation

Hawaii law excludes the following from state taxable income:

  • Social Security and Railroad Retirement Act benefits (HRS §235-7(a)(3))
  • Employer-funded pension income (HRS §235-7(a)(3))
  • Military retired pay (HRS Chapter 235 as applied by the Department)
  • Workers’ compensation benefits
  • Certain energy-related income for qualifying technology businesses (HRS §235-7.3)
  • Interest on U.S. government obligations is deductible for Hawaii purposes

Standard Deduction and Exemptions

Standard Deduction (Tax Year 2025)
Filing Status Standard Deduction
Single $4,400
Married Filing Jointly $8,800
Married Filing Separately $4,400
Head of Household $6,424
Qualifying Surviving Spouse $8,800

Personal Exemptions

Hawaii allows personal exemptions of $1,144 per exemption (Tax Year 2025).

Exemptions are available for:

  • Taxpayer (self): $1,144
  • Spouse (if not filing separately): $1,144

Itemized Deductions

Hawaii generally follows federal itemized deductions with some differences and phase-out limitations for higher-income taxpayers. Taxpayers who itemize must use Schedule A (Form N-11) or the equivalent N-15 schedule. Key itemized deductions available in Hawaii include:

  • Medical and dental expenses (above federal AGI threshold)
  • State and local taxes paid (subject to limitations)
  • Mortgage interest and real property taxes
  • Charitable contributions
  • Casualty and theft losses (subject to restrictions)

Note: Hawaii does not allow a deduction for state and local income taxes on the Hawaii return (only relevant for multi-state filers). The Hawaii itemized deduction limitations may differ from federal limits for high-income taxpayers.

Hawaii Income Tax Credits

Hawaii offers numerous tax credits to reduce state income tax liability. The following are the most commonly claimed credits available for Tax Year 2025:

1. Food/Excise Tax Credit (Refundable)

Hawaii’s most frequently claimed tax credit. This refundable credit helps offset the General Excise Tax paid by lower-income taxpayers on purchases of food and basic goods.

Eligibility: Hawaii resident for more than 9 months of the tax year; income below the threshold; not claimed as a dependent on another return.
Form: Form N-311
Source: https://files.hawaii.gov/tax/forms/current/n311_i.pdf and https://tax.hawaii.gov/geninfo/

2. Earned Income Tax Credit (EITC) — Refundable

Hawaii’s EITC is 40% of the federal EITC amount allowed. The credit became refundable starting Tax Year 2023 (Act 163, SLH 2023).

2025 Change: Act 25, SLH 2025 requires nonresidents claiming the refundable EITC to multiply the credit by the ratio of Hawaii adjusted gross income to federal adjusted gross income.

Eligibility: Must qualify for the federal EITC; income limits apply (same general structure as federal EITC).
Source: https://tax.hawaii.gov/geninfo/ and https://tax.hawaii.gov/tax-year-information/

3. Child and Dependent Care Credit

Hawaii allows a credit for expenses paid for the care of qualifying children and dependents to enable the taxpayer (and spouse) to work or look for work.

Eligibility: Hawaii resident taxpayers who qualify for the federal Child and Dependent Care Credit; income and expense limits apply.
Source: https://tax.hawaii.gov/geninfo/

4. Credit for Taxes Paid to Another State or Foreign Country

Hawaii residents who pay income tax to another state or foreign country on income also taxed by Hawaii may claim a credit on Schedule CR to avoid double taxation.

Requirements:

  • Income was earned while a Hawaii resident
  • Income derived from sources outside Hawaii
  • Tax paid to the other jurisdiction is an income-based tax
  • No credit is allowed for city or local income taxes paid to another state

Form: Schedule CR (attached to Form N-11 or N-15)
Source: https://tax.hawaii.gov/geninfo/ (Schedule CR instructions)

5. Renewable Energy Technologies Income Tax Credit (RETITC)

Hawaii offers a credit for the cost of installing eligible renewable energy technology systems (solar water heating, photovoltaic systems, etc.) on residential property in Hawaii.

Eligibility: Property must be located in Hawaii; system must meet statutory requirements.
Statutory authority: HRS §235-12.5
Source: https://tax.hawaii.gov/geninfo/

6. Pass-Through Entity (PTE) Tax Credit

Members of qualifying partnerships or S corporations that have elected to pay Hawaii income tax at the entity level may claim a credit for their pro-rata share of PTE taxes paid.

2025 Change: Act 58, SLH 2025 requires qualifying members to add their share of PTE taxes paid back to taxable income before claiming the credit.
Form: Schedule CR, line 13; or Form N-362

7. High Technology Business Investment Tax Credit

Hawaii offers incentives for qualified investments in qualified high technology businesses, including credits under HRS §235-110.9.

Special Considerations for Hawaii Income Tax

Remote Workers and Multi-State Taxation

Living in Hawaii, Working for an Out-of-State Employer

As a Hawaii resident, you owe Hawaii income tax on all income, regardless of where your employer is located. This is a fundamental principle of Hawaii residency taxation.

What this means:

  • Your employer’s location does not determine your Hawaii tax obligation
  • Income from mainland employers — California, New York, Texas, or any other state — is fully taxable in Hawaii
  • Hawaii requires proper Hawaii tax withholding for resident employees, using Form HW-4

Example: A Hawaii resident working remotely for a New York employer owes Hawaii income tax on 100% of that income.

Source: https://files.hawaii.gov/tax/legal/har/har_235.pdf (HAR §18-235-4-02)

Working in Hawaii, Living in Another State

Non-residents who perform work physically in Hawaii owe Hawaii income tax on income earned from Hawaii sources.

Physical Presence Rule: Income is sourced to Hawaii based on where the work is physically performed. If a nonresident employee spends part of the year working in Hawaii, only wages earned during Hawaiian work days are taxable in Hawaii.

Withholding threshold: Hawaii has a day-based withholding threshold — employers generally need not withhold Hawaii income tax for nonresident employees who work in Hawaii for only a small number of days. Once the threshold is exceeded, withholding is required for all Hawaii workdays.

Source: https://tax.hawaii.gov/geninfo/a2_b2_4empl_whhold_employee/ and Tax Foundation analysis of Hawaii nonresident rules


⚠️ Interstate Tax Risk Indicator

Remote workers with connections to Hawaii face particular complexity because of Hawaii’s physical isolation — most income-earning activities involving Hawaii residents and mainland employers create multi-state filing obligations.

States requiring special attention for Hawaii-connected remote workers:

  • California — Aggressive residency audits for individuals with California business ties; California-source income rules are strict
  • New York — Applies the “convenience of the employer” rule (see below), potentially taxing remote work days for NY-based employers
  • Pennsylvania — 200+ local income tax jurisdictions create complexity for PA-employed Hawaii residents
  • Connecticut — Applies a modified “convenience of the employer” rule; complex credit system for taxes paid to other states
  • Massachusetts — Telecommuter rule historically applied to remote workers for MA employers

Source: https://tax.hawaii.gov/geninfo/ and IRS Publication 505 (https://www.irs.gov/publications/p505)


“Convenience of the Employer” Rule

Hawaii does NOT apply the “convenience of the employer” rule.

Hawaii sources nonresident income based on where the work is physically performed. A nonresident working remotely from Hawaii for a Hawaii employer is not automatically subject to Hawaii income tax on all income — only income from work physically performed in Hawaii is sourced to Hawaii for nonresident purposes.

However, Hawaii residents are taxed on all income regardless of employer location — this is not a “convenience rule” but rather the standard residency-based worldwide income taxation.

Important distinction: If you are a Hawaii resident working remotely for any employer anywhere, Hawaii taxes 100% of your wages. If you are a non-resident working remotely from outside Hawaii for a Hawaii employer, only days worked physically in Hawaii are Hawaii-sourced.

Source: https://files.hawaii.gov/tax/legal/har/har_235.pdf and https://files.hawaii.gov/tax/legal/taxfacts/tf97-4.pdf


Reciprocal Agreements

Hawaii has no reciprocal tax agreements with any other state.

Hawaii’s geographic isolation as a Pacific island state makes reciprocal agreements with any mainland state uncommon. As of Tax Year 2025, no reciprocal agreements exist between Hawaii and any other U.S. state.

What this means for Hawaii residents working in other states:

  • You must file a nonresident return in the state where you physically worked
  • You file a resident return in Hawaii reporting all income
  • You may claim a credit on your Hawaii return (Schedule CR) for income taxes paid to other states on the same income

What this means for non-Hawaii residents working in Hawaii:

  • You must file a Hawaii nonresident return (Form N-15) for Hawaii-source wages
  • Your home state may allow a credit for taxes paid to Hawaii

Source: https://tax.hawaii.gov (no reciprocity page — confirms absence of agreements)


Multi-State Tax Filing for Hawaii Residents

When earning income in multiple states:

  1. File a Hawaii resident return (Form N-11) reporting all income from all sources
  2. File nonresident returns in other states where income was earned from sources in those states
  3. Claim a credit on your Hawaii return for state income taxes paid to other states

Forms required:

  • Schedule CR — Credit for Taxes Paid to Another State or Foreign Country (attached to Form N-11)
  • Form N-15 (if you are a part-year resident — separate issue from claiming a credit)

Limitations:

  • The credit for taxes paid to another state may not exceed the Hawaii tax otherwise due on that income

Tax Residency vs. Domicile in Hawaii

Domicile Defined

Domicile is your permanent legal home — the place where you intend to return and consider “home” indefinitely.

Key characteristics:

  • You can have only one domicile at a time
  • Domicile continues until you establish a new domicile elsewhere with intent to remain
  • Temporary absences — including extended work assignments, military service, or school — do not change domicile
  • Intent to return is the critical factor

Factors establishing Hawaii domicile (HAR §18-235-1):

  • Where you maintain your primary residence
  • Where you register to vote
  • Where you hold a Hawaii driver’s license
  • Where you file a homestead exemption
  • Where your family resides
  • Where you maintain bank accounts and financial ties
  • Stated intent in legal documents (wills, trusts)
  • Where you belong to organizations and engage in community life

Residency Defined

Residency for Hawaii tax purposes is established by domicile. Unlike some states, Hawaii primarily uses a domicile-based residency test rather than a day-count statutory residency test.

Under HAR §18-235-1.02:

  • A resident is an individual domiciled in Hawaii
  • A nonresident is an individual whose permanent domicile is outside Hawaii — even if temporarily present in Hawaii
  • A part-year resident is someone who was domiciled in Hawaii for part of the year and outside Hawaii for the other part

Hawaii does not have a standard 183-day statutory residency test in the way states like New York or California do. Residency is determined primarily by domicile and intent.

Practical consequence: A person who spends 300 days in Hawaii for work purposes but maintains their permanent home (domicile) in another state is generally a Hawaii nonresident — taxable only on Hawaii-source income.

Establishing or Changing Hawaii Domicile

To establish a new domicile in Hawaii, three elements are required (HAR §18-235-1.03):

  1. Abandonment of the prior domicile
  2. Actual physical presence in Hawaii
  3. Intent to make Hawaii the permanent home — no present intention to leave

All three elements must be satisfied simultaneously. Simply moving to Hawaii temporarily or for employment does not establish Hawaii domicile if the intent is to eventually return elsewhere.

To abandon Hawaii domicile, a person must:

  1. Leave Hawaii physically
  2. Establish a new domicile in another location with intent to remain
  3. Show clear and convincing evidence of the change

Military Personnel and Domicile

Servicemembers Civil Relief Act (SCRA):
Active duty military members stationed in Hawaii under military orders do not become Hawaii residents solely due to military orders. They continue to pay income tax to their state of legal residence (domicile).

Military Spouses Residency Relief Act (MSRRA):
Spouses of active duty military members may maintain their home state residency and are not subject to Hawaii income tax on income earned in Hawaii if:

  • The servicemember is in Hawaii solely to comply with military orders
  • The military spouse is in Hawaii only to be with the servicemember
  • The military spouse maintains domicile in another state

Military spouses may use Form HW-6 to notify their Hawaii employer of exemption from Hawaii withholding.

What military members DO owe Hawaii tax on:
Hawaii residents serving in the military (domicile in Hawaii) owe Hawaii income tax on:

  • Investment income
  • Rental income from Hawaii property
  • Non-military income earned in Hawaii

Full-time active duty military pay for Hawaii-domiciled service members is taxable in Hawaii.

Common Conflict Scenarios

Scenario 1: Mainland employee relocated to Hawaii

  • Background: California resident takes a 2-year assignment in Hawaii, maintains California home, family stays in California
  • Tax result: Likely remains a California resident (domicile), filing as a Hawaii nonresident. Hawaii taxes only Hawaii-source wages. California taxes all income with a credit for taxes paid to Hawaii.

Scenario 2: Hawaii resident moving to the mainland

  • Background: Hawaii resident moves to Texas for a job, but keeps Hawaii home and family in Hawaii
  • Tax result: May remain a Hawaii resident (domicile) if Hawaii home and family ties remain. Intent is critical. Hawaii taxes all income worldwide.

Scenario 3: Remote worker moving to Hawaii

  • Background: California-domiciled remote worker moves to Hawaii “indefinitely” with no current intention to return to California
  • Tax result: Likely establishes Hawaii domicile on the move date. From that date, all income is taxable in Hawaii. California part-year resident return required for pre-move income.

Hawaii-Specific Audit Triggers

Common patterns that trigger Hawaii residency audits:

  • Maintaining Hawaii driver’s license or vehicle registration while claiming non-residency
  • Owning property in Hawaii while filing as a non-resident
  • Spouse or children remaining in Hawaii while taxpayer claims non-residency elsewhere
  • Returning to Hawaii frequently from claimed “new domicile”
  • High-income individuals claiming to have changed domicile away from Hawaii

Burden of Proof: In Hawaii residency disputes, the burden falls on the taxpayer to prove non-residency or change of domicile by clear and convincing evidence (HAR §18-235-1.03).

Active duty military members stationed in Hawaii due to military orders:

  • Do not become Hawaii residents solely due to military orders
  • Pay income tax to their state of legal residence (domicile)
  • Are not subject to Hawaii income tax on military pay from their home-state domicile

  • All military retired pay (disability and non-disability)
  • Survivor Benefit Plan (SBP) annuities
  • Reserve Component Survivor Benefit Plan (RCSBP) annuities
  • Retired Serviceman’s Family Protection Plan (RSFPP) annuities

What Hawaii-Domiciled Military Members DO Owe Tax On

Military members who are Hawaii residents (domicile in Hawaii) owe Hawaii income tax on:

  • Investment income (dividends, interest, capital gains)
  • Rental income from Hawaii or non-Hawaii property
  • Business income
  • Non-military wages earned in Hawaii
  • Full-time active duty military pay (Hawaii-domiciled service members)

Source: https://files.hawaii.gov/tax/legal/taxfacts/tf97-2.pdf

Retirees

Hawaii is generally considered retirement-friendly from an income tax standpoint due to its broad pension and Social Security exemptions.

Social Security Benefits

Hawaii fully exempts Social Security benefits from state income tax — no portion is taxable, regardless of total income. This is one of the most favorable Social Security tax treatments in the nation.

Source: HRS §235-7(a)(3) — https://files.hawaii.gov/tax/legal/hrs/hrs_235.pdf

Pension Income

Employer-funded pensions are fully excluded from Hawaii taxable income under HRS §235-7(a)(3). This covers:

  • State of Hawaii Employee Retirement System (ERS) pensions
  • County government pensions
  • Federal government pensions (FERS and CSRS) — employer-funded portion
  • Private employer defined benefit pensions — employer-funded portion
  • Teachers’ pensions

Employee-funded portion: If you contributed to your pension on a pre-tax basis, a portion of distributions may be taxable. A Schedule J calculation (exclusion ratio) is used to determine the tax-free and taxable portions each year.

Source: https://files.hawaii.gov/tax/legal/tir/1990_09/tir96-5.pdf

Retirement Account Distributions

Traditional 401(k) and Traditional IRA: Pre-tax contributions and earnings distributed in retirement are fully taxable in Hawaii at progressive rates.

Roth IRA: Qualified distributions are not subject to Hawaii income tax.

Annuities: The exclusion ratio applies to determine the tax-free recovery of cost basis vs. taxable earnings portion of annuity payments.

Source: https://files.hawaii.gov/tax/legal/tir/1990_09/tir96-5.pdf and https://files.hawaii.gov/tax/forms/2023/schj_i.pdf (Schedule J instructions)

Military Retirement Pay

Fully exempt from Hawaii income tax. SBP, RCSBP, and RSFPP annuities are also not taxable in Hawaii.

Source: https://files.hawaii.gov/tax/legal/taxfacts/tf97-2.pdf

Estate Tax Note

Hawaii imposes an estate tax on estates exceeding $5.49 million with rates ranging from 10% to 20%. This is separate from income tax but relevant for estate planning for Hawaii retirees.

Students

College students attending school in Hawaii do not automatically become Hawaii residents for tax purposes.

You remain a nonresident if:

  • You maintain legal residence (domicile) in another state
  • Your presence in Hawaii is temporary for educational purposes
  • You intend to return to your home state after graduation or studies

You owe Hawaii tax only on Hawaii-source income:

  • Wages earned from working in Hawaii (part-time jobs, internships, etc.)
  • Business income from Hawaii operations

Establishing Hawaii residency as a student:
Students can become Hawaii residents if they take affirmative steps to establish domicile in Hawaii:

  • Register to vote in Hawaii
  • Obtain a Hawaii driver’s license
  • Express intent to remain in Hawaii after graduation
  • Maintain continuous presence with no plans to return to home state

Source: https://files.hawaii.gov/tax/legal/har/har_235.pdf (HAR §18-235-1.03)

Part-Year Residents

If you moved to or from Hawaii during 2025, you are required to file as a part-year resident using Form N-15 (Individual Income Tax Return — Nonresident and Part-Year Resident).

Income Allocation

  • Report all income earned while a Hawaii resident (from all sources worldwide)
  • Report Hawaii-source income earned while a nonresident
  • Exclude income earned outside Hawaii while a nonresident

The part-year resident rules under Tax Facts 97-4 provide specific guidance on income allocation, including proration of deductions and exemptions based on the residency period.

Moving TO Hawaii

  • Calculate Hawaii residency start date (the day you establish Hawaii domicile)
  • Report all income from that date forward on the Hawaii resident section
  • File a nonresident or part-year resident return in your former state for income earned before moving

Moving FROM Hawaii

  • Calculate Hawaii residency end date (the day you establish domicile elsewhere)
  • Report all income through that date on the Hawaii resident section
  • File a nonresident or part-year resident return in your new state

Key point: Income earned outside Hawaii while a nonresident is not taxable in Hawaii, even if it is related to your employment period in Hawaii. Carryovers of deductions for business losses incurred before becoming subject to Hawaii’s taxing jurisdiction may not be claimed (Tax Facts 97-4).

Common Tax Filing Situations

Situation: “My employer is in California/another state, so I don’t owe Hawaii tax.”

Hawaii law: Hawaii residents owe tax on all income regardless of employer location. If you are domiciled in Hawaii, 100% of your wages — regardless of where your employer is incorporated or headquartered — is subject to Hawaii income tax.

Source: https://files.hawaii.gov/tax/legal/har/har_235.pdf (HAR §18-235-4-02)


Situation: “I work remotely, so I only owe tax in my employer’s state.”

Tax law principle: As a Hawaii resident, you owe Hawaii income tax on all income. Additionally, if your employer is in a state that taxes nonresidents (such as New York, which applies the “convenience of the employer” rule), you may also owe that state’s tax — and may then claim a credit on your Hawaii return.

Source: https://tax.hawaii.gov and IRS Publication 505


Situation: “I filed a federal extension, so my Hawaii return is also extended.”

Hawaii law: Hawaii does not accept federal extension forms. Hawaii’s automatic extension is separate from the federal extension and is governed by Hawaii’s own rules. Paying estimated taxes due by April 20, 2026 is required to qualify for the Hawaii automatic extension.

Source: https://tax.hawaii.gov/tax-year-information/ and https://tax.hawaii.gov/faq/


Situation: “I’m a part-year resident, so I owe half the tax.”

Hawaii law: Part-year residents owe tax on income earned during the Hawaii residency period, and on Hawaii-source income earned during the nonresident period. This is not a simple 50% reduction — it depends on actual income earned during each period.

Source: https://files.hawaii.gov/tax/legal/taxfacts/tf97-4.pdf

Filing Deadlines

Regular Deadline

April 20, 2026 for Tax Year 2025 returns — note this is April 20, not April 15.

Extension Deadline

October 20, 2026 (automatic 6-month extension)

How to receive the automatic extension:

  • No form is required to request the extension
  • You must either be due a refund, OR have paid at least 90% of your final tax liability by April 20, 2026
  • File your completed return by October 20, 2026 with full payment of any remaining balance

Important: The extension is for filing only — it does not extend the time to pay taxes owed. Taxes owed must be paid by April 20, 2026 to avoid penalties and interest.

Estimated Tax Payments

If you have income not subject to withholding (self-employment, investment income, rental income, etc.), quarterly estimated payments are due:

  • Q1: April 20, 2026
  • Q2: June 20, 2026
  • Q3: September 20, 2026
