Hawaii compliance obligations

Hawaii landlords commonly track 6 state and local compliance obligations, each listed below with its schedule, its sources, and the date we last verified it. Among them: file periodic Hawaii GET returns (Form G-45), file the Hawaii GET annual return and reconciliation (Form G-49), and pay the first-half real property tax installment by August 20.

File periodic Hawaii GET returns (Form G-45)

Hawaii general excise tax applies to gross rent, and each periodic Form G-45 return is due by the 20th of the month after its filing period ends (April 20, July 20, October 20, and January 20 for quarterly filers), even for a period with no rent, and a late return adds a penalty of 5 percent of the tax per month, up to 25 percent, plus interest.

File the Hawaii GET annual return and reconciliation (Form G-49)

Hawaii general excise tax applies to gross rent, and the annual Form G-49 return that reconciles the year's periodic returns is due by the 20th day of the fourth month after the tax year ends (April 20 for calendar-year filers), and filing late adds penalties and interest, while filing more than 12 months late can cost any GET exemptions or deductions claimed.

Pay the first-half real property tax installment by August 20

All four Hawaii counties bill real property tax in two installments, and the first half of the July to June tax year is due August 20, with late payments charged a penalty of up to 10 percent plus interest of 1 percent a month.

Return the security deposit or itemized deductions within 14 days of lease end

Within 14 days after the rental agreement ends, return the full deposit or send the tenant a written list of deductions with receipts or estimates plus any remaining balance, because a landlord who misses the deadline loses the right to keep any of it and a court may award three times the amount wrongfully and willfully withheld.

Verify smoke alarms are installed and working, and test any CO alarms

Hawaii landlords must keep rentals in line with the state and county fire codes, which require working smoke alarms in dwelling units, so an annual check that each alarm sounds, that one sits outside every sleeping area and on each level, that dead batteries and alarms over ten years old are replaced, and that any carbon monoxide alarms also work keeps tenants safe and the unit compliant.

Seasonal maintenance for Hawaii

Landlords in Hawaii plan upkeep around a humid climate: this guide lists 6 seasonal maintenance items for Hawaii in calendar order, each with its timing and the date we last verified it. Among them: schedule the annual termite and moisture inspection, do a post-wet-season mold and ventilation check, and complete hurricane readiness checks before the June 1 season start.

Inspect coastal metalwork and HVAC for salt-air corrosion

Salt spray from the ocean speeds corrosion of exposed metal, including the outdoor air conditioner, railings, exposed fasteners, and the hurricane clips and connectors that hold a house together, so on properties near the shore a quarterly check that rinses salt off the air conditioner and looks for rust catches damage before it weakens the structure or forces an early replacement.

Schedule the annual termite and moisture inspection

Formosan ground termites are Hawaii's most economically important insect pest, with control and repair costs estimated at over $100 million a year, and their large swarms fly on warm, humid evenings in May and June, so a March professional inspection that also checks any bait stations, plus clearing wood, cardboard, and plants away from the foundation and fixing leaks that keep the soil damp, finds activity early and makes the home less inviting before the swarms.

Do a post-wet-season mold and ventilation check

Hawaii's lowland humidity commonly averages 60 to 80 percent and winter storms bring its heaviest rains from October to April, so a mid-April check of bathrooms, closets, window tracks, and air conditioner drain lines for leaks and mold, with fans, dehumidifiers, or air conditioning keeping indoor humidity below 60 percent, catches moisture damage before it spreads.

Complete hurricane readiness checks before the June 1 season start

Hawaii's hurricane season runs June 1 to November 30 and peaks in August and September, so in May checking the roof and whether hurricane clips or straps tie it to the walls, clearing gutters and drains, trimming dead or weak limbs, sizing window protection, photographing the property, and confirming hurricane and flood coverage, including any condominium association policy (standard homeowner policies do not include either, and a new flood policy usually takes 30 days to start), readies the property before storms arrive.

Peak-season storm drainage and sump check

Confirming drainage and sump operation at peak hurricane season prevents flooding damage.

Clear gutters and roof drains and check the roof before the wet season

Hawaii's heaviest rains come from winter storms, including Kona storms, between October and April, so clearing gutters, downspouts, roof drains, and flat-roof scuppers and checking the roof in early October helps prevent leaks, interior water damage, and mold.
