Taxes in Kailua
Kailua and Hawaii's real, current 2026 tax picture is genuinely mixed: a top income tax rate of 11% (among the highest in the nation), a General Excise Tax that is legally distinct from a sales tax, and a paradoxically low-RATE-but-disputed-structure property tax picture.

Learn moreHawaii's Income Tax Runs Among the Nation's Highest
Hawaii applies a real, current 12-bracket graduated individual income tax for 2026, running from 1.4% up to a top marginal rate of 11% (applying above $200,000 single-filer / $400,000 joint-filer taxable income) -- among the highest top marginal rates in the country. The 2026 standard deduction is $4,400 single / $8,800 joint, under a real, still-phasing-in Act 46 (2024) reform, with a further 13% top bracket arriving in tax year 2027 (not 2026).
Social Security Is Fully Exempt; Employee-Contributed Retirement Income Is Not
Hawaii does not tax Social Security income at all, and fully exempts employer-funded pension income from state income tax. This record discloses a real, precise limitation directly: the employee-contributed portion of any retirement plan, along with 401(k) and traditional IRA distributions, remains fully taxable at Hawaii's regular income tax rates.
Hawaii's GET Is Legally Not a Sales Tax
Hawaii's General Excise Tax (GET) taxes business gross receipts rather than consumer purchases. The statewide base rate is 4.0% for 2026; the City and County of Honolulu (which includes Kailua) levies an additional 0.5% county surcharge, for a combined 4.5% rate on most Oahu transactions, with a real pass-on gross-up effect that can push what a business charges to fully recover the tax to approximately 4.712%.
Property Tax Runs Paradoxically Low-RATE, With a Real, Disclosed Structure Conflict
As detailed on the property-taxes topic page, this record's primary cited blended effective rate (~0.28%) runs genuinely low nationally, but this record discloses a real, unresolved cross-source conflict on the exact owner-occupied rate structure, producing a wide illustrative dollar-bill range of roughly $2,200-$4,700/year on a typical Kailua home.
Key takeaways
- Hawaii's real, current top income tax rate is 11% for 2026, applying above a relatively modest $200,000 single-filer threshold, with a further 13% bracket arriving in tax year 2027.
- Social Security is fully exempt from Hawaii income tax; employee-contributed retirement income (401(k)/IRA) is not.
- Hawaii's GET (4.5% combined on Oahu) is legally distinct from a sales tax, taxing business gross receipts.
- Property tax runs paradoxically low-RATE but produces a real, substantial and disputed dollar bill -- confirm a specific property's actual bill directly.
