1031 Exchange in Hawaii: High Taxes, Unique Market Dynamics

The tax case for exchanging in Hawaii

Hawaii taxes capital gains as ordinary income at rates up to 11%. Combined with federal capital gains tax (up to 23.8% including the net investment income tax), a Hawaii investor selling appreciated property faces a combined tax rate that can exceed 34%.

On a $1,000,000 gain, that is $340,000+ in taxes. A 1031 exchange defers the entire amount — both federal and state.

This makes Hawaii one of the states where 1031 exchanges deliver the most absolute dollar value. The higher the tax rate, the more powerful the deferral.

Hawaii's tax environment for real estate investors

General excise tax on rental income

Hawaii imposes a General Excise Tax (GET) on gross rental income, not net income. The effective rate is 4.5% on Oahu and 4% on the neighbor islands. Unlike most states' sales taxes, the GET applies to services including rental income, and it is assessed on the landlord, not the tenant (though it can be passed through).

This is a significant ongoing cost that reduces effective rental yields. On $5,000/month in rent on Oahu, the GET adds $225/month ($2,700/year) in tax, regardless of your expenses or profitability.

HARPTA: Hawaii's withholding for non-residents

The Hawaii Real Property Tax Act (HARPTA) requires buyers to withhold 7.25% of the gross sale price when purchasing from a non-resident seller. This is not a tax — it is a prepayment of the seller's expected state income tax liability.

For exchangers, HARPTA creates a cash flow challenge: 7.25% of your gross sale price is withheld at closing, reducing the proceeds available for your exchange. You can apply for a reduced withholding certificate (Form N-312) if your actual tax liability will be less than the standard withholding, but this requires advance planning and processing time.

Critical planning point: If you are a non-resident selling Hawaii property in a 1031 exchange, file Form N-312 well before closing to request reduced or zero withholding based on the exchange deferral. Without this, 7.25% of your gross proceeds will be withheld, potentially jeopardizing your ability to acquire replacement property of equal or greater value.

Leasehold vs. fee simple: the Hawaii distinction

Hawaii has a uniquely high proportion of leasehold properties, particularly on Oahu. In a leasehold arrangement, you own the building but lease the land from a landowner (often a trust or estate) for a fixed term, typically 30-75 years.

1031 implications of leasehold:

• A leasehold interest in real property with 30+ years remaining is generally treated as like-kind to fee simple real property for 1031 purposes
• As the lease term shortens, the property depreciates toward zero — fundamentally different from fee simple appreciation
• Lease renegotiations can dramatically increase ground rent, destroying investment returns
• Financing leasehold property is more difficult and more expensive

Recommendation: For 1031 exchanges, strongly prefer fee simple properties unless you have deep experience with Hawaii leasehold dynamics. The declining value of a shortening lease can erode or eliminate the deferral benefit if the replacement property loses value.

Island-by-island market analysis

Oahu

The most liquid market with the highest prices. Honolulu multifamily and condos dominate the investment landscape. Cap rates are compressed (3.5-5% for residential investment property) due to limited land and strong demand.

Short-term rental restrictions: Honolulu passed strict regulations limiting vacation rentals outside resort-zoned areas. Many residential investment properties that previously generated STR income are now restricted to long-term rentals, reducing revenue potential. Verify the zoning and STR eligibility of any Oahu property before identifying it as replacement property.

Maui

Tourism-driven with significant resort and condo inventory. The market was impacted by the 2023 Lahaina wildfire, and recovery and rebuilding continue to shape supply and demand dynamics. Maui County has implemented its own short-term rental regulations that differ from Oahu's.

Cap rates for resort-area condos are higher than Oahu (5-7%) but come with tourism-cycle volatility and increasingly restrictive STR rules.

Big Island (Hawaii Island)

More affordable than Oahu or Maui with a wider range of property types, including agricultural land, rural residential, and resort condos. Kona-side properties command premiums over Hilo-side. Cap rates are generally higher (5-7%) reflecting lower liquidity and higher vacancy risk.

Kauai

The smallest major-island market with the most restrictive development environment. Very limited inventory makes the 45-day identification period particularly challenging. Prices are high relative to rents, and STR regulations are actively tightening.

Common exchange scenarios

Inter-island upgrade: Maui condo investor exchanges into an Oahu apartment building. Moves from tourism-dependent income to stable long-term residential rental demand. Sacrifices yield for stability and liquidity.

Mainland-to-Hawaii lifestyle exchange: California investor exchanges a Central Valley apartment complex into a Kona-side duplex. The numbers are tighter due to Hawaii's lower cap rates, but the investor values the Hawaii lifestyle component for eventual personal use (note: personal use restrictions apply during the exchange holding period — at least two years of investment use required).

Hawaii-to-mainland diversification: Oahu investor sells an appreciated Waikiki condo with $600,000 gain, exchanges into Texas or Florida multifamily. Eliminates Hawaii's 11% state tax exposure and captures higher cap rates. Must file Form N-312 to reduce HARPTA withholding.

Leasehold-to-fee-simple conversion: Investor sells a leasehold property with a shortening lease term and exchanges into a fee simple property, improving long-term value preservation while deferring the gain.

Identification period challenges in Hawaii

Hawaii's limited inventory creates real risk during the 45-day identification period. On neighbor islands in particular, there may be only a handful of suitable replacement properties available at any given time.

Mitigation strategies:

• Begin property research 3-6 months before selling your relinquished property
• Work with a Hawaii-based agent who understands 1031 timelines and can pre-screen inventory
• Consider identifying mainland properties as alternates to protect the exchange
• Use a DST as a safety-net identification — several DSTs hold Hawaii properties
• Identify the maximum number of properties your identification rules allow

Property tax by county

Hawaii property taxes vary significantly by county and property classification. Investment properties are taxed at higher rates than owner-occupied residences.

Note: Rates change annually. The Big Island's higher nominal rate is offset by lower assessed values. Always calculate the actual dollar amount based on your specific property's assessed value.

Pre-exchange checklist for Hawaii

• Determine if the property is fee simple or leasehold — and if leasehold, verify the remaining lease term exceeds 30 years
• File Form N-312 for HARPTA withholding reduction well before closing (if you are a non-resident seller)
• Verify short-term rental eligibility and zoning for any replacement property
• Calculate the GET impact on projected rental income (4-4.5% of gross rent)
• Research the specific county's property tax rate for the investment classification
• Confirm the replacement property's flood zone, lava zone, and insurance availability
• Budget for higher insurance costs, particularly for windstorm and flood coverage
• Factor in the conveyance tax on both your sale and your purchase
