GET Tax Essentials for Oahu Short- and Long-Term Rentals

Protect rental cash flow with correct GET handling

When GET isn't handled correctly, it shrinks your monthly cash flow and raises audit risk. Hawaii's General Excise Tax, or GET, is a tax on a business's gross income, not a consumer sales tax.

On Oahu the combined rate for rental income is 4.5%. Short-term stays under 180 days often trigger the Transient Accommodations Tax as well, so you may face multiple filing requirements.

This guide gives a practical checklist owners can use immediately. We'll cover registration, rates, filing cadence, recordkeeping, and manager oversight so you preserve income and reduce audit exposure. See how our flat-fee management handles GET filings and reporting.

How GET and TAT change what you keep from rent

Are you renting by the night or by the month? The tax rules treat those two situations very differently.

Stays under 180 consecutive days are short-term for Hawaii tax purposes and trigger the Transient Accommodations Tax in addition to GET. Long-term rentals of 180 days or more do not owe TAT, but they still fall under GET.

What rates you need to budget for

On Oahu the combined General Excise Tax for rental income is 4.5%. Some owners choose to pass GET to tenants and use a 4.712% pass-on rate to fully recover the liability.

Short-term rentals add the state TAT and the county surcharge on top of GET. The state TAT is 11.0% and Honolulu adds a 3.0% county TAT, producing about an 18.5% combined burden on short-term gross receipts.

Which rental receipts are taxable

• Base rent is fully subject to GET and must be reported as gross rental income.
• Cleaning fees and guest service fees received from renters are taxable income.
• Mandatory add-on charges, like included utilities billed through you, count as taxable receipts.
• Any portion of a security deposit you retain for damages or unpaid rent becomes taxable when kept.
• Late fees, lease-break charges, and similar penalties are taxable and should be reported.
• Payments the tenant pays directly to a utility company are not your income and are not taxable to you.

The practical impact is straightforward: short-term listings need higher effective pricing to cover taxes. If you charge a nightly rate, factor in the roughly 18.5% combined rate so your net revenue targets hold up.

You remain legally responsible for registration and filing even if a manager handles day-to-day operations. We document and report GET and TAT for owners as part of our flat-fee management approach so your statements match tax filings. Learn how our flat-fee management handles GET and reporting

Get registered and set the right GET filing schedule

Worried GET will eat into your rental profits or trigger penalties? Start by confirming you must register.

Research from the Hawaii Department of Taxation shows anyone "engaging in business" in Hawaii must register for GET. That definition includes residential and short‑term rental owners, freelancers, and remote businesses that meet nexus thresholds.

Registering with the BB-1 on Hawaii Tax Online

Complete the Basic Business Application (Form BB-1) to get a GET license. You can register online through Hawaii Tax Online for the fastest processing.

BB-1 asks for your business name, entity type, EIN, address, and business activity description. There is a one-time $20 license fee and online processing typically issues a GE- number in 5 to 7 business days.

Choosing filing frequency and meeting deadlines

Filing frequency is set by your expected annual GET liability, not just gross rent. Research from the Department of Taxation defines the thresholds for monthly, quarterly, and semiannual filing.

File monthly if annual GET liability exceeds $4,000. File quarterly for $2,001 to $4,000, and semiannually for $2,000 or less. For tax years after 2022, taxpayers with $100 or less annual liability may not need periodic returns.

Periodic returns use Form G-45 and you must file an annual reconciliation on Form G-49. Periodic returns are due by the 20th day following the reporting period and the G-49 is due April 20.

You must file a zero return if you have no income for a reporting period. Keep records of gross receipts and business activity for seven years to support filings.

Common penalty triggers include late filing, late payment, and operating without a license. Penalties can reach 5% per month up to 25%, a 20% penalty if unpaid after 60 days, plus interest of two thirds of one percent per month.

• Estimate your annual GET liability now so the Department assigns the right filing frequency.
• Register with Form BB-1 through Hawaii Tax Online and pay the $20 fee to get your GE- number.
• Confirm your assigned filing cadence and note G-45 due dates on the 20th following each period.
• File your annual G-49 reconciliation by April 20 and keep seven years of records.
• File a zero return when a period has no income so you avoid late‑filing penalties.
• If your income grows, contact the Department to update your filing frequency to avoid retroactive penalties.
• Consider having a local manager handle registration and filings so you stay compliant. Learn how property managers take care of GET registration and reporting in our Oahu property management guide.

Follow this checklist to lock in proper registration and avoid common penalties. Staying on the correct filing cadence protects cash flow and reduces audit risk.

Monthly and annual GET checks every off‑island owner should require

Managing tax risk from afar means asking for the right reports on a predictable schedule. We recommend a short monthly review and a deeper annual reconciliation to protect cash flow and limit audit exposure.

Monthly documents to request from your manager

• A detailed income and expense statement that separates gross rent, cleaning fees, and any guest charges.
• A booking export that shows platform bookings and direct bookings so you can reconcile sources of income.
• Proof of remittance for any GET/TAT payments the manager made on your behalf, such as payment confirmation numbers or receipts.
• Backup for vendor reimbursements and pass‑through charges, including original invoices showing who actually paid the vendor.
• Access to an owner portal or shared cloud folder where all monthly statements and tax receipts are stored.

Platform-collected taxes complicate reconciliation but do not remove your reporting duty. Many booking platforms collect and remit GET for platform bookings, yet you must still register, report gross receipts, and keep audit-quality records.

Reconciling platform remittances versus direct bookings

Treat platform and direct income as separate lanes in your ledger so totals are easy to match to tax filings. For platform bookings, confirm the amount the platform reported and compare it with the booking export and the manager’s statements.

For direct bookings, ensure the manager has applied the correct GET rate to gross receipts and remitted payments when required. We recommend monthly spot checks to catch discrepancies early.

Verification steps that prove filings and audit‑quality records

• Request copies of the periodic GET returns submitted in your name, such as completed G-45 forms or filing confirmations.
• Ask for payment receipts or transaction IDs from Hawaii Tax Online as proof the tax was actually remitted.
• Match gross receipts on monthly statements to the amounts reported on the returns and to any platform reports you receive.
• Get an annual reconciliation that lines up total gross rent, GET paid, and the IRS 1099 or year-end summary you use for tax prep.
• Confirm records are retained for seven years and kept in a searchable digital folder in case of audit.

Do these checks monthly and demand the annual reconciliation without fail. Consistent documentation and a short verification routine are the best defenses against lost revenue and audit headaches.

Owner checklist to lock in GET compliance

Worried GET will eat into your rental income? Use this short checklist to reduce audit risk and preserve cash flow.

• Register with Form BB-1 on Hawaii Tax Online to get your GE- number and avoid licensing penalties.

• Include GET correctly when pricing or show it as a separate taxable charge so you recover the liability.
• Keep centralized digital records of gross receipts and supporting invoices for seven years and run an annual reconciliation.
• Verify manager remittances monthly by requesting G-45 copies, Hawaii Tax Online receipts, and booking exports to match gross receipts.
