Moving to Hawaii

Hawaii taxes residents on everything, nonresidents on Hawaii-source income only, and the year of a move on both, split by date. A resident is anyone domiciled in Hawaii, or anyone living here for more than a temporary or transitory purpose, and a person domiciled elsewhere who spends more than 200 days of the year in Hawaii is presumed to be a resident unless they can show a permanent home somewhere else and a temporary reason for being here. Residents file Form N-11. Part-year residents and nonresidents file Form N-15, which taxes all income received while a resident plus Hawaii-source income for the rest of the year, and prorates the standard deduction and exemptions by the share of total income that is Hawaii’s. Hawaii has no reciprocal agreement with any state, so wages earned here by a nonresident are taxed here, and wages earned elsewhere by a Hawaii resident are taxed here too, with a credit for the other state’s tax. And HARPTA takes 7.25% of the sale price when a nonresident sells Hawaii real estate.

Resident, nonresident, part-year

Domicile is the anchor. It is “the place where someone has a true, fixed, permanent home and principal establishment,” and you have only one. Changing it takes three things at once: abandoning the old domicile, intending to establish the new one, and actually being physically present there. The Department of Taxation says in its guidance to military families that “a single act, such as getting an in-state driver’s license, is insufficient.” What persuades is the whole picture: where your home is and what became of the old one, where your family lives, where you vote, bank, register cars and see doctors.

Then there is the 200-day presumption. Someone domiciled elsewhere who is in Hawaii more than 200 days of the tax year is presumed to be a resident, taxable on worldwide income. It can be rebutted with evidence of a permanent place of abode outside Hawaii and a temporary or transitory purpose for being here, but the burden is on the taxpayer. A mainland retiree who winters at a Maui condo from October through April is at about 210 days and has a problem; so does an eight-month work assignment. The fix is fewer days or a file that proves the other home is the real one.

The year you move: Form N-15

A part-year resident reports on Form N-15 in two columns: Column A is total income from all sources for the whole year, Column B is the Hawaii-taxed part. Income received while a resident goes in Column B regardless of where it was earned; income received as a nonresident goes in Column B only if it is Hawaii-source. The ratio of Column B to Column A, on line 37, then prorates the standard deduction and the $1,144 exemptions, so a couple who were Hawaii residents for half the year and earned half their income here get roughly half of the $16,000 deduction and half of the $2,288 of exemptions. Itemized deductions are prorated the same way. The tax is computed on the Hawaii taxable income from the regular rate schedule, the same brackets residents use.

What counts as Hawaii-source income is listed in the N-15 instructions: wages and other pay for services performed in Hawaii, profits from a Hawaii business or profession, rent from Hawaii property, gains on Hawaii real estate and other property with a Hawaii situs, Hawaii partnership and S corporation income, Hawaii trust and estate income, and unemployment benefits paid by Hawaii. “Income from the performance of personal services has its source at the place where the services are performed.” Interest, dividends and stock gains are sourced to the owner’s domicile, so a nonresident’s brokerage account is not Hawaii income and a resident’s is.

Retirement income follows the same split. Pension, IRA and Social Security payments received while a resident go on the Hawaii side and are then subtracted to the extent Hawaii exempts them; payments received after a move out are not Hawaii-source at all, because federal law bars a state from taxing the retirement income of a former resident. The Hawaii treatment of each kind of retirement income is in Hawaii for retirees.

No reciprocity, and the credit for tax paid elsewhere

Hawaii has no reciprocal agreement with any state. A Hawaii resident who earns wages in another state owes Hawaii tax on them and owes the other state as well if it taxes nonresidents’ wages, and the relief is a credit on the Hawaii return for the tax paid to the other state, limited to the Hawaii tax on the same income. It is claimed on Schedule CR and carried to line 35 of the N-11 as a nonrefundable credit, and a copy of the other state’s return goes with it. Because Hawaii’s rates run to 11%, the credit usually absorbs the whole of the other state’s tax and leaves a Hawaii balance.

The credit is for residents; a nonresident taxed by Hawaii looks to the home state for relief under that state’s rules.

Remote work across the ocean

Hawaii sources wages where the work is physically performed and has no convenience-of-the-employer rule. A Hawaii resident working from a Kailua spare bedroom for a Seattle or San Francisco company is earning Hawaii-source income, taxable by Hawaii in full, and not taxable by the employer’s state unless that state reaches out to remote workers on its own account; the employer should be withholding Hawaii tax on Form HW-4, and many mainland employers are slow to do so. The reverse case, a mainland resident working remotely for a Honolulu employer, produces no Hawaii-source wages; if Hawaii tax was withheld anyway, an N-15 showing zero Hawaii wages gets it back. Hybrid workers split by days worked in each place. The person most exposed is the one who moved to Hawaii, kept a mainland address and employer, and never filed here.

Military and spouses

A servicemember stationed in Hawaii under orders keeps the home state of record and is a nonresident of Hawaii; the Department’s Tax Facts 97-2 says plainly that “if you are a nonresident of Hawaii, you do not have to pay Hawaii income tax on the wages you earn for serving on active duty.” Other Hawaii income, a part-time job or a Hawaii rental, is taxed on an N-15. A civilian spouse who came to Hawaii only because of the orders and shares the servicemember’s domicile, or has elected it, is a nonresident too, and under the Military Spouses Residency Relief Act the spouse’s Hawaii wages are not Hawaii-source income; the spouse files an N-15, marks the MSRRA oval and attaches the documents to recover any withholding. A Hawaii-domiciled servicemember stationed elsewhere remains a Hawaii resident and files an N-11; up to $8,636 of reserve and National Guard duty pay is excluded (2025 figure; 2026 to come), and military retired pay is exempt in full.

Leaving Hawaii: the audit and HARPTA

A move out is a change of domicile, and the same three elements apply in reverse; keep the closing statement or lease termination, the new state’s license and the moving invoice. Hawaii-source income stays Hawaii’s: a rental left behind means an N-15 every year and a general excise tax return besides, and the eventual sale brings HARPTA.

HARPTA is Hawaii’s withholding on real estate sales by nonresidents, and it is the move-out trap. When a nonresident sells Hawaii real property the buyer must withhold 7.25% of the amount realized, which is generally the full sales price, not the gain, and pay it to the Department on Form N-288 within 20 days of closing. On a $900,000 condo that is $65,250 out of the seller’s proceeds at the closing table, regardless of how small the gain is. A seller who is still a Hawaii resident avoids it by giving the buyer Form N-289, a certification of residency; so does a seller whose sale is a nonrecognition transaction such as a like-kind exchange, or who sold a principal residence for $300,000 or less. A former resident who has moved away cannot sign the N-289 as a resident. The money is not lost: the seller files Form N-288B before closing for a reduced withholding certificate, or Form N-288C after closing for a tentative refund, and in either case files an N-15 for the year of sale claiming the withholding as a payment. The actual tax is on the gain only, and the federal home-sale exclusion flows through because it reduces federal AGI. Sell before you change domicile and there is no withholding; sell after and there is a year of waiting for your own money.

What to do the year you move

• Fix the date. The day you arrived with the intent to stay, or left with the intent not to return, is the day the N-15 splits on. Write it down and keep the evidence.
• Change the payroll. Give a Hawaii employer Form HW-4 the first week. Tell a mainland employer you are now a Hawaii resident so Hawaii, not the old state, is withheld.
• Count the days if you are not sure you have moved. Over 200 in Hawaii, with a home elsewhere, needs a file.
• If you keep a Hawaii rental after leaving, register for the general excise tax and expect an N-15 every year.
• Selling Hawaii property? Sell while still a resident, or file N-288B before closing.
• Expect estimated payments in the first full Hawaii year if you have IRA, rental or self-employment income; Hawaii’s threshold is $500 and nothing is withheld on any of it.
