Hawaii Income Tax Calculator 2026

Reading Hawaii's 12 tax brackets

Hawaii has more brackets than any other state, twelve, running from 1.4% to 11%. Joint filers' bracket thresholds are exactly double the single thresholds, and heads of household get 1.5 times. The 2024 tax law (Act 46) widened the lower and middle brackets, which is why a single filer now stays in the 7.6% bracket all the way from $48,000 to $125,000.

Taxable income is federal AGI after Hawaii adjustments, less the standard deduction ($4,400 single, $8,800 joint, $6,424 head of household) or itemized deductions, less $1,144 for each exemption. On $70,000 a single filer has $64,456 of taxable income and owes about $3,790 (5.41%).

Worked example: family of four

A married couple filing jointly with two children and $120,000 of wages deducts the $8,800 joint standard deduction and four $1,144 exemptions ($4,576), leaving $106,624. The joint schedule produces $5,886 of Hawaii tax, an effective rate of 4.90% and a marginal rate of 7.6%. Refundable credits such as the food/excise tax credit and the Hawaii EITC can reduce that for lower-income families; they are not included here.

Retirement income in Hawaii

Hawaii distinguishes between pensions your employer paid for and savings you funded yourself:

• Social Security and first-tier Railroad Retirement benefits are not taxed.
• Pensions from employer-funded plans are exempt. That includes public pensions (federal civil service, military, state and county retirement systems) and private pensions to the extent the employee did not contribute.
• If you contributed to a private pension, the part of each payment attributable to your contributions is taxable.
• IRA, 401(k) and similar plans you funded yourself are generally taxable when withdrawn, as are early distributions subject to the federal penalty.
• Long-term capital gains are taxed at a maximum of 7.25%, lower than the top ordinary rates.

April 20, not April 15

Hawaii's filing deadline is five days later than the federal one. For 2026, Form N-11 is due April 20, 2027. If you cannot file by then, you get an automatic six-month extension to October 20, but any tax due must still be paid by April 20 (with Form N-200V). Estimated tax payments for individuals follow the same 20th-of-the-month pattern.

Residents, part-year residents and the 200-day rule

Hawaii residents file Form N-11 and are taxed on all income. Part-year residents and nonresidents must use Form N-15, which taxes income from Hawaii sources (and all income while a resident).

You are a resident if you are domiciled in Hawaii, or if you live there for other than a temporary or transitory purpose. Anyone in Hawaii for more than 200 days of the tax year is presumed to be a resident, though you can rebut that by showing a permanent home elsewhere and a temporary purpose for being in Hawaii. Military members do not gain or lose Hawaii residency just by being stationed there under orders.
