Hawaii taxes capital gains as ordinary income at rates up to 11%, which puts the combined federal and state burden among the highest in the nation. A 1031 exchange is one of the few ways to defer that hit. The catch is local: leasehold property, HARPTA withholding on non-resident sellers, island-by-island short-term rental rules, and very thin inventory all demand knowledge a mainland-focused exchanger may not have.
The tax case for exchanging in Hawaii
Sell an appreciated investment property in Hawaii and the tax can take more than a third of the gain.
Hawaii taxes capital gains as ordinary income, at rates up to 11%. Add the federal capital gains tax, which can reach 23.8% once the net investment income tax is included, and an investor selling appreciated property here can face a combined rate above 34%.
On a $1,000,000 gain, that is $340,000+ owed. A 1031 exchange defers all of it, state and federal.
That math is why Hawaii is one of the states where deferral is worth the most in absolute dollars. The higher the rate, the more the deferral is worth.
Hawaii's tax environment
Tax Component | Rate / Detail |
|---|---|
State income tax (top rate) | 11% |
Capital gains treatment | Taxed as ordinary income |
HARPTA withholding (non-residents) | 7.25% of gross sale price |
General excise tax on rent | 4.5% (Oahu) / 4% (other islands) |
Property tax rates | Vary by county and use class |
Conveyance tax | 0.10%-1.25% graduated by price |
The general excise tax on rent
Hawaii charges a General Excise Tax (GET) on gross rental income rather than net profit. The effective rate is 4.5% on Oahu and 4% on the neighbor islands. Most states' sales taxes skip services; Hawaii's GET applies to rent, and it falls on the landlord, not the tenant, though it is often passed through.
Because it hits gross rent, it is a cost you pay whether or not the property makes money. At $5,000 a month in rent on Oahu, the GET adds $225 a month, or $2,700 a year.
HARPTA: withholding when a non-resident sells
The Hawaii Real Property Tax Act (HARPTA) requires the buyer to withhold 7.25% of the gross sale price when the seller is a non-resident. It is not an extra tax but a prepayment of the seller's expected Hawaii income tax.
For an exchanger, the timing is the problem. That 7.25% comes out at closing and shrinks the proceeds available to roll into the replacement property. A seller whose actual liability will be lower can apply for reduced withholding on Form N-312, but that takes advance planning and processing time.
If you are a non-resident selling Hawaii property in an exchange, filing Form N-312 well before closing is what requests reduced or zero withholding based on the deferral. Without it, 7.25% of gross proceeds is withheld, which can leave you short of the amount needed to buy replacement property of equal or greater value.
Leasehold and fee simple in Hawaii
Hawaii has an unusually high share of leasehold property, especially on Oahu. In a leasehold, you own the building but lease the land under it from a landowner, often a trust or estate, for a fixed term, typically 30 to 75 years.
For a 1031 exchange, that structure matters in a few ways. A leasehold with 30 or more years remaining is generally treated as like-kind to fee simple real property, so it qualifies. But a lease is a wasting asset: as the term shortens, its value drifts toward zero, the opposite of how fee simple land tends to behave. Ground rent can jump sharply at renegotiation, and financing a leasehold is harder and costs more.
Factor | Fee Simple | Leasehold |
|---|---|---|
Land ownership | Yes | No (leased) |
Typical price discount | n/a | 20-50% below fee simple |
Appreciation potential | Full | Declines as lease shortens |
Financing availability | Standard | Limited; shorter terms |
1031 eligibility | Yes | Yes (if 30+ years remain) |
Ground rent | None | $500-$3,000+/month |
The reason this distinction gets so much attention is simple: a deferral only helps if the replacement property holds its value. If a shortening lease drags that value down, the tax you deferred can be swamped by the value you lost.
Island-by-island market
Oahu
Oahu is the most liquid market and the most expensive. Honolulu multifamily and condos are the core of the investment landscape, and cap rates - the yearly net income a property throws off as a percentage of its price - run compressed, roughly 3.5% to 5% for residential investment property, because land is scarce and demand is strong.
Honolulu has passed strict limits on vacation rentals outside resort-zoned areas. Many properties that once earned short-term rental income are now restricted to long-term tenants, which lowers the revenue they can produce. Zoning and short-term rental eligibility are worth confirming on any Oahu property before it goes on an identification list.
Maui
Maui runs on tourism, with heavy resort and condo inventory. The 2023 Lahaina wildfire reshaped supply and demand, and rebuilding is still underway. Maui County has its own short-term rental rules, separate from Oahu's. Cap rates on resort-area condos run higher than Oahu's, around 5% to 7%, but they come with the swings of the tourism cycle and tightening STR rules.
Big Island (Hawaii Island)
The Big Island is more affordable than Oahu or Maui and offers a wider range of property, from agricultural land to rural residential to resort condos. Kona-side properties command a premium over the Hilo side. Cap rates tend to be higher, about 5% to 7%, reflecting thinner liquidity and higher vacancy risk.
Kauai
Kauai is the smallest of the major-island markets and the hardest place to build. Inventory is very limited, which makes the 45-day identification window especially tight. Prices are high relative to rents, and short-term rental rules are tightening.
Common exchange scenarios
Inter-island upgrade. A Maui condo investor exchanges into an Oahu apartment building, trading tourism-dependent income for steadier long-term residential demand, and giving up yield for stability and liquidity.
Mainland-to-Hawaii lifestyle exchange. A California investor exchanges a Central Valley apartment complex into a Kona-side duplex. The numbers are tighter because Hawaii's cap rates are lower, but the investor is buying the lifestyle for eventual personal use. Personal-use rules apply during the holding period: the property needs at least two years of investment use first.
Hawaii-to-mainland diversification. An Oahu investor sells an appreciated Waikiki condo with a $600,000 gain and exchanges into Texas or Florida multifamily, shedding Hawaii's 11% state tax exposure and picking up higher cap rates. This one requires filing Form N-312 to reduce HARPTA withholding.
Leasehold-to-fee-simple conversion. An investor sells a leasehold property with a shortening term and exchanges into fee simple, preserving long-term value while still deferring the gain.
The 45-day clock in a thin market
Hawaii's limited inventory is a real hazard during the 45-day identification period. On the neighbor islands especially, only a handful of suitable replacement properties may exist at any moment.
Things exchangers do to manage that risk:
- Start property research 3 to 6 months before the relinquished property sells
- Work with a Hawaii-based agent who understands 1031 timelines and can pre-screen inventory
- Line up mainland properties as backup identifications to protect the exchange
- Use a Delaware Statutory Trust (DST) - a structure that lets you own a fractional interest in property and still counts as like-kind replacement - as a safety-net identification; several DSTs hold Hawaii property
- Identify the maximum number of properties the identification rules allow
Property tax by county
Property taxes swing widely by county and by how the property is classified. Investment property is taxed at higher rates than an owner-occupied home.
County | Residential (investor) rate per $1,000 | Homeowner rate per $1,000 |
|---|---|---|
Honolulu | ~$3.50 | ~$3.50 (with exemption) |
Maui | ~$5.55 | ~$2.41 |
Hawaii (Big Island) | ~$10.70 | ~$6.15 |
Kauai | ~$5.05 | ~$2.49 |
Rates change every year, and the Big Island's higher nominal rate is offset by lower assessed values. The number that matters is the actual dollar amount on your property's assessed value.
Pre-exchange checklist for Hawaii
Model your tax savings along with the GET, property tax, and insurance costs for a specific Hawaii target.
Because Hawaii taxes capital gains at rates up to 11%, the bill a 1031 exchange defers here is larger than in most states. The complications are local: the fee-simple-versus-leasehold question, HARPTA withholding, and short-term rental eligibility all shape the result, and each takes more due diligence than a typical mainland exchange.
Frequently asked questions
What is HARPTA and how does it affect my 1031 exchange in Hawaii?
HARPTA (the Hawaii Real Property Tax Act) requires the buyer to withhold 7.25% of the gross sale price when the seller is a non-resident. That money is a prepayment of your Hawaii tax. In a 1031 exchange, you can apply for a reduced withholding certificate on Form N-312 before closing, since the exchange defers the gain, and that can lower or eliminate the withholding. Processing takes time, so it has to be filed early.
Can I exchange a leasehold property in a 1031 exchange?
Yes. A leasehold interest generally qualifies for 1031 treatment when 30 or more years remain on the term. The complication is that a lease is a wasting asset: as the term shortens, its value declines toward zero, so a replacement leasehold can lose value over the years you hold it. That is why the fee-simple-versus-leasehold question gets so much weight in Hawaii exchanges.
How does Hawaii's General Excise Tax affect rental property income?
Hawaii's GET applies to gross rental income at 4.5% on Oahu and 4% on the neighbor islands. Unlike most state taxes, it is charged on gross revenue rather than net profit, so you owe it even in a year the property loses money. On $4,000 a month of rent on Oahu, that is $180 a month, or $2,160 a year, before any expenses.
Are short-term rentals restricted in Hawaii for 1031 exchange properties?
Short-term rental rules vary by county and are tightening across all the islands. Honolulu limits vacation rentals outside resort zones, and Maui County has its own permitting requirements. Confirming a property's STR eligibility with the county before identifying it as replacement property tells you which income stream it can actually produce: a property zoned for long-term rental only earns considerably less than one permitted for vacation use.
