What Is the Property Tax Rate in San Francisco, Hawaii and How Is It Calculated for a New Buyer

Hawaii property taxes are administered at the county level, not the state level. San Francisco, Hawaii falls within Hawaii County, which covers the entire Big Island. That means the rates, exemptions, and payment schedules you need to know are set by Hawaii County, not by a statewide authority. This is different from most mainland states, and it is the first thing new buyers need to internalize before reading any tax estimate.

Assessed Value vs. Market Value

Your tax bill is based on assessed value, which is not always the same as the price you paid. Hawaii County assessors determine the assessed value of each property, typically aiming to reflect full market value. In practice, assessed values can lag behind rapidly moving sale prices, especially in a market like the Big Island where demand has pushed values upward over recent years. As of September 2026, many properties in Hawaii County are being assessed close to their recent sale prices, so new buyers should not assume a large gap between what they paid and what the assessor will use.

The assessor reviews each parcel annually, and your assessed value can increase year over year. There is no state constitutional cap on assessment increases in Hawaii the way California's Proposition 13 limits increases to 2% per year. This means your tax bill can rise meaningfully if the assessor determines your property's value has increased, which is an important planning consideration for buyers coming from California.

Tax Classification: Why Your Property Type Matters

Hawaii County assigns every property a tax classification, and the classification determines which rate applies. The main classifications relevant to residential buyers are Residential (Class A), Residential Investment (Class B), and Affordable Rental Housing. Residential applies to owner-occupied homes. Residential Investment applies to properties that are rented out or not occupied by the owner as a primary residence. The difference between these two rates is substantial, so your intended use of the property directly affects your annual tax cost.

Vacation rentals and short-term rental properties are typically classified as Residential Investment or a separate short-term rental category, depending on current county ordinances. If you are purchasing a property in San Francisco, Hawaii with any intention of renting it out, confirm the applicable classification with Hawaii County before closing so there are no surprises on your first tax bill. You can verify classifications directly through the Hawaii County Real Property Tax Division.

2. The Property Tax Rate in San Francisco, Hawaii: Current Figures for 2026

The property tax rate in San Francisco, Hawaii for the 2026 tax year is set by Hawaii County and expressed per $1,000 of net assessed value. For the fiscal year covering 2025 to 2026, Hawaii County's Residential (owner-occupied) rate is $6.15 per $1,000 of assessed value. The Residential Investment rate, which applies to non-owner-occupied residential properties, is $11.10 per $1,000. These figures represent the base rates before any exemptions are applied. For a detailed breakdown of current rates and a calculation tool, Hawaii Property Taxes 2025-26: Rates, Exemptions and Examples provides a comprehensive county-by-county reference.

Residential vs. Non-Owner-Occupied Rates

The gap between the Residential and Residential Investment rates is nearly $5 per $1,000, which translates to a meaningful dollar difference on most Big Island purchases. On a home assessed at $600,000, an owner-occupant pays approximately $3,690 per year at the $6.15 rate. The same property classified as Residential Investment generates a tax bill of approximately $6,660 per year at the $11.10 rate. That is nearly $3,000 more annually, simply based on whether you live in the home as your primary residence. This is why classification and exemption status are not administrative details; they are budget line items.

How the Rate Is Applied to Your Assessed Value

The rate is always applied to the net assessed value, meaning the assessed value after any exemptions have been subtracted. If your home is assessed at $700,000 and you qualify for the basic Home Exemption of $40,000, your net assessed value is $660,000. You then multiply $660,000 by the applicable rate per $1,000 to arrive at your annual tax. The county does not apply the rate to the gross assessed value before exemptions, so claiming your exemption early matters.

3. How Property Tax Is Calculated for a New Buyer in San Francisco, Hawaii

For a new buyer, the calculation follows a clear sequence. Understanding each step prevents the common mistake of budgeting based on the seller's previous tax bill, which may reflect a different assessed value, a different exemption status, or even a different classification than what will apply to you.

Step-by-Step Calculation Walkthrough

Step one is determining your assessed value. After you close, Hawaii County will assign or update the assessed value for the property. For recently sold properties, the assessor often uses the sale price as a strong indicator of market value, so your purchase price is a reasonable starting point for estimating your first year's tax.

Step two is confirming your classification. Decide whether you will occupy the home as your primary residence. If yes, you will file for the Residential classification and the Home Exemption. If the property will be rented or used as a vacation home, it will be classified as Residential Investment and taxed at the higher rate.

Step three is subtracting your exemptions. The basic Home Exemption for owner-occupants in Hawaii County is $40,000 off the assessed value. Buyers aged 60 to 69 receive a $80,000 exemption, and buyers aged 70 and older receive a $100,000 exemption. Subtract the applicable exemption from your assessed value to get your net assessed value.

Step four is applying the rate. Divide your net assessed value by 1,000, then multiply by the applicable rate. For a $550,000 assessed value with a $40,000 Home Exemption, the net assessed value is $510,000. Divided by 1,000 gives 510. Multiplied by the $6.15 Residential rate gives an annual tax of $3,136.50. Divided by two gives a semi-annual payment of $1,568.25.

What Changes After You Close

The seller's most recent tax bill is not your future tax bill. If the previous owner had a different exemption status, an older assessed value that lagged behind the market, or a different classification, their bill could look very different from yours. Always ask your agent to pull the current assessed value from the Hawaii County Real Property Tax Division records, not just the tax amount shown on the listing.

Your first full tax year as the new owner will reflect the assessed value the county assigns after your purchase. In the year of closing, taxes are typically prorated between buyer and seller at settlement, so you will see a credit or charge on your closing disclosure. After that, you are responsible for the full annual bill going forward. If you are using a mortgage with an escrow account, your lender will collect a monthly amount toward taxes and pay the county on your behalf.

4. Exemptions That Can Reduce Your Tax Bill

Hawaii County offers several exemptions that directly lower the net assessed value on which your tax is calculated. The most important one for new buyers is the Home Exemption, but there are others worth knowing before you file. Missing an exemption you qualify for means overpaying, and the county does not automatically apply most exemptions; you have to claim them.

The Home Exemption

The Home Exemption is the primary tax relief tool for owner-occupants in Hawaii County. To qualify, you must own and occupy the property as your principal home as of October 1 of the tax year. The deadline to file your Home Exemption claim with Hawaii County is December 31 of the year preceding the tax year in which you want the exemption to apply. If you close on your home in July 2026 and file by December 31, 2026, the exemption applies to your 2027 tax year. If you miss that deadline, you wait another year.

The exemption amounts by age group for Hawaii County are as follows. Owners under age 60 receive a $40,000 reduction in assessed value. Owners aged 60 to 69 receive an $80,000 reduction. Owners aged 70 and older receive a $100,000 reduction. These amounts apply to the assessed value before the tax rate is multiplied, so the actual dollar savings on your bill depend on the rate in your classification.

For a thorough overview of how Hawaii's property tax exemptions work across all counties, the Understanding Hawaii's Property Taxes guide from Hawaii Life is a well-organized reference that covers the Home Exemption filing process and age-based tiers in detail.

Other Exemptions Worth Knowing

Hawaii County also offers a Low-Income Home Exemption for qualifying owner-occupants whose household income falls below a threshold set by the county. This exemption provides a significantly larger reduction in assessed value than the standard Home Exemption, and income limits are reviewed periodically. Buyers who expect their household income to be modest relative to local benchmarks should check current thresholds directly with the Hawaii County Real Property Tax Division, as the qualifying figures are adjusted and the savings can be substantial.

There is also an exemption available for totally disabled veterans and their surviving spouses, as well as an exemption for properties owned by certain nonprofit organizations. If you or a co-owner on the deed has a service-connected disability rating, contact the county tax office to confirm eligibility before assuming the standard exemption is the best you can do. These exemptions are not widely publicized during the buying process, but they exist and they matter.

5. Paying Your Property Taxes: Deadlines, Penalties, and Practical Tips

Hawaii County collects property taxes in two installments per year, not monthly or quarterly. Knowing the payment schedule prevents late fees, which can add up quickly on a bill that may already be several thousand dollars.

Payment Schedule in Hawaii County

The first installment covers the period from July 1 through December 31 and is due by August 20. The second installment covers January 1 through June 30 and is due by February 20. Payments received after those dates are subject to a penalty of 10% on the unpaid amount, plus interest that accrues monthly. If you are paying out of pocket rather than through an escrow account, mark these dates on your calendar the moment you close.

Hawaii County accepts payment online, by mail, or in person at the county offices in Hilo. For buyers in San Francisco, Hawaii who are not physically on the island year-round, the online payment portal is the most practical option. The county mails tax bills to the address on record, so make sure your mailing address is updated with the Real Property Tax Division promptly after closing, particularly if you will be managing the property remotely.

How to Budget for Taxes Before You Close

Build your tax estimate into your monthly ownership budget before you make an offer, not after. Divide your estimated annual tax by 12 and add it to your expected mortgage payment, insurance, and any HOA fees. For a property assessed at $700,000 with a $40,000 Home Exemption and the $6.15 Residential rate, the annual bill is approximately $4,059, which is roughly $338 per month. That number belongs in your affordability calculation from the start.

If your lender requires an escrow account, they will estimate the annual tax at closing and collect one-twelfth each month along with your mortgage payment. Lenders often collect an initial escrow cushion at closing, typically two to three months of estimated taxes, so factor that into your closing cost budget as well. Your lender is required to provide an escrow analysis annually, and if the tax bill comes in higher than estimated, your monthly payment will be adjusted accordingly.

One more planning note: if you purchase a property that was previously classified as Residential Investment and you intend to occupy it as your primary residence, your tax bill will drop once you successfully file for the Home Exemption and the county reclassifies the property. This reclassification does not happen automatically at closing. You must file the exemption claim and the county must process it. Budget conservatively using the Residential Investment rate for your first partial year, then plan for the lower Residential rate to take effect once your exemption is approved.
