If you rent out a beach cottage, a spare condo, or even a houseboat to overnight guests anywhere in Delaware, the state now takes 4.5% of every stay — and the question of who sends that money to Dover trips up more hosts than the tax itself. Get the answer wrong and you are either collecting tax you were never supposed to touch, or failing to file returns the state expects from you every single month, busy season or not.
This guide walks through exactly how Delaware's short-term rental lodging tax works: what it covers, who collects it, the $25 license, the monthly filing deadline, and a bookkeeping setup that keeps the whole thing painless.
What the tax is and when it started
Delaware imposes a short-term rental lodging tax of 4.5% of the rent on every occupancy of a short-term rental in the state (30 Del. C. ch. 62). It comes from House Substitute 2 for House Bill 168, signed in late September 2024, and it applies to rental agreements entered into on or after January 1, 2025. The Division of Revenue's published FAQs and its Technical Information Memorandum 2024-1 spell out the mechanics — and the mechanics contain several surprises for first-time hosts.
A short-term rental is a house, duplex, multi-plex, apartment, condominium, houseboat, trailer, or other residential dwelling unit where a tourist or transient guest rents sleeping or living accommodations for no more than 31 consecutive nights. Note the boundary: a 31-night stay is in scope, a 32-night stay is not, and month-to-month holdover rent after a lease rolls over is excluded from the tax base entirely.
Several categories are carved out. The tax does not cover hotels, motels, and tourist homes (those operate under a separate hotel/motel/tourist-home license), assembly rooms, dormitories and residential facilities of educational institutions, state-licensed healthcare facilities, campsites and cabins in campgrounds, overnight camps, or a genuinely casual arrangement where the owner rents directly, charges substantially below market rates, and rents no more than 10 nights total in the calendar year. That last exemption is narrow by design — a regularly listed vacation rental at market rates will not qualify.
One more thing the tax does not do: replace local taxes. If a Delaware municipality imposes its own lodging or rental tax, you still collect and remit that to the municipality separately. The state tax is an additional layer, not a substitute.
What counts as taxable rent (and what does not)
The 4.5% applies to "rent" — the consideration received for occupancy, whether in money or otherwise. But several common line items on a guest folio are excluded:
- Municipal taxes
- Linen rental fees
- Cleaning fees
- Insurance fees
- Security deposits
- Other add-on fees not usually considered part of the rent
- Money received from a month-to-month holdover lease
This distinction matters more than it looks. On a $1,000 weekend booking with a $150 cleaning fee and a $50 linen charge, the tax base is $1,000, not $1,200 — a $9 difference on a single stay that compounds across a season. Hosts who apply 4.5% to the all-in total over-collect from every guest and create reconciliation headaches when payouts do not tie to returns. Hosts who forget that the nightly rate, pet fees tied to occupancy, and similar charges generally are part of rent under-collect and owe the difference themselves.
Build your listing and your books so that rent and excludable fees are separate line items from the start. If your platform or channel manager lumps everything into one "payout" figure, you will need the per-charge breakdown to file correctly.
Who collects and remits: the intermediary rule
Delaware assigns collection duty to the "accommodations intermediary" — any person in the business of facilitating or arranging a short-term rental to an occupant on a website or through other means, including timeshare-plan rentals. Real estate brokers of record fall in this bucket too (though individual licensees working under the broker do not take on the duty personally).
In practice there are two scenarios, and knowing which one you are in is the whole ballgame:
You list only through a third-party platform. If every booking comes through a company like Airbnb, Vrbo, Booking.com, Expedia, Tripadvisor, or a local listing service, then only that platform collects and remits the tax. You do not collect it, you do not file for it, and you do not need a state business license for it — even if your town or county requires a municipal license. The platform, however, must hold a Delaware accommodations intermediary license itself.
You take any direct bookings. If you accept reservations yourself — through your own website, by phone, by repeat-guest email, or any channel where no licensed intermediary sits between you and the occupant — you are the accommodations intermediary for those stays. You must collect the tax, remit it, and hold the $25 Delaware accommodations intermediary business license. This is true even if 90% of your volume runs through a platform: the direct-booked 10% is your responsibility, with its own filing obligation.
The mixed-channel host is the most common compliance trap. A host who assumes "Airbnb handles my taxes" while also taking two direct bookings a month off-platform has unfiled liability for every one of those direct stays.
The $25 license and where your license number must appear
Accommodations intermediaries must obtain a Delaware business license for $25 through the state's OneStop registration portal before conducting intermediary services. For a direct-booking owner, that means getting licensed before your first direct stay — not at year-end, not when you get around to it.
Delaware also requires intermediaries to include their license number in all marketing materials. Practically, that means your direct-booking website, your social media booking posts, and any print advertising should display it. Treat the license number the way a contractor treats a license number on a truck: visible, current, and on everything that solicits business.
Platform-only hosts need no state license, but verify that each platform you use is licensed and actually collecting Delaware tax on your listings. A platform payout that shows no tax line for a Delaware stay deserves a support ticket, because the liability framework assumes the platform is doing its part.
Filing: monthly, on the portal, by the 15th
The mechanics are straightforward but unforgiving on timing:
- Where: the Division of Revenue's online taxpayer portal.
- When: the tax collected for each month is filed and paid no later than the 15th day of the following month. January collections are due February 15, July collections August 15, and so on.
- Even with no bookings: registered operators must file a return for each assigned filing period, even periods with zero rental income and zero tax collected. An empty month is still a filing obligation. Calendar it as recurring, not as something you remember when guests check in.
- What data to report: at a minimum, your identifying information (including business license), the address of each rental unit, the number of nights rented for each unit, and the aggregate rents collected for each property. If you run three cottages, the state wants per-property figures, not one blended number — another reason to keep property-level books.
When to collect, and what happens on cancellation
Collect the tax no later than the earlier of the final payment of all rent due or the guest's occupancy. For most hosts that means the tax is in hand before or at check-in, never chased afterward.
If a stay is cancelled in whole or in part, the cancelled portion is not subject to the tax, and any tax already collected on that portion must be refunded. Your cancellation workflow should therefore reverse the tax line automatically alongside the rent refund — refunding the nightly rate but keeping the tax is exactly backwards, and it leaves you remitting money the state says was never due.
Penalties: why a missed month gets expensive fast
Delaware stacks three separate charges on noncompliance, so a single skipped filing can snowball:
- Late filing: 5% of the tax due per month, plus interest at 0.5% per month from the original due date until paid.
- Late payment on a timely return: an additional 1% per month, capped at 25%, on any liability shown on the return but not paid.
- Missing, incomplete, or data-deficient returns: intermediaries face additional interest and penalties for failing to file, filing incomplete returns, or failing to remit the property-level data the Division requires.
A $400 monthly liability filed three months late does not cost $400 — it costs the tax plus roughly 15% in filing penalties plus accruing interest, before any payment penalty. And because zero-income periods still require returns, "I had no guests so I filed nothing" can draw penalties with no underlying tax at all. Set up the recurring filing first; optimize later.
A bookkeeping setup that makes this automatic
Lodging-tax compliance is mostly bookkeeping discipline. Here is a structure that works for one property or ten:
1. Separate tax collected from revenue — always
Create a dedicated liability account (for example, "Delaware STR Lodging Tax Payable") and post every dollar of collected tax there at booking or check-in, never into rental income. When you remit, the payment reduces the liability to zero. At any moment, the account balance should equal exactly what you owe the state for unfiled periods. If it does not, something is wrong, and you will catch it before the 15th rather than after a penalty notice.
2. Track rent vs. excludable fees per stay
Keep nightly rent and occupancy-linked charges in revenue accounts, and cleaning fees, linen charges, deposits, and similar excludables in their own accounts. This gives you the taxable base per stay without reconstructing it from payout emails at filing time — and it documents your exclusion math if the Division ever asks.
3. Reconcile platform payouts gross-to-net
Platform payouts typically arrive net of platform fees, and sometimes net of taxes the platform remitted on your behalf. Record the gross rent, the platform fee expense, and any platform-collected tax separately rather than booking the net deposit as revenue. A monthly reconciliation — payout report to bank deposit to tax return — should tie to the penny. When it does not, the usual culprits are a mid-month fee change, a refunded stay, or a direct booking mixed into the wrong batch.
4. Keep per-property records
Because the return requires per-unit addresses, nights rented, and aggregate rents, maintain those three figures per property as part of your monthly close: nights occupied, gross taxable rent, tax collected, tax remitted, and filing confirmation number. A one-page monthly schedule per property satisfies both the return and any future audit, and it doubles as the occupancy data you need for pricing decisions.
5. Run a pre-15th checklist
A few days before each deadline: confirm every stay is entered, confirm cancellations reversed their tax lines, confirm direct-booking tax sits in the liability account, file and pay on the portal, save the confirmation, and clear the liability balance. Five steps, ten minutes, zero penalties.
Common mistakes to avoid
- Taxing the cleaning fee. The most frequent over-collection error. Excludable add-ons stay out of the base.
- Assuming the platform covers direct bookings. It does not. Any stay without a licensed intermediary in the middle is yours to collect, report, and remit.
- Skipping zero-income returns. Registered means filing every assigned period, guests or no guests.
- Forgetting municipal tax. The state return does not satisfy the town. Track and remit each layer separately.
- Hiding the license number. It belongs in your marketing materials, not in a drawer.
- Commingling tax with revenue. The moment collected tax looks like income, you will spend it, misreport it, or both. Liability account, every time.
Keep Your Short-Term Rental Books Audit-Ready
Delaware's lodging tax is simple at its core — 4.5% of rent, collected by whoever sits between the guest and the property, filed by the 15th — but it punishes casual recordkeeping with monthly penalties and per-property reporting that rewards hosts who track every stay cleanly. Separating taxable rent from fees, holding collected tax in its own liability account, and reconciling platform payouts every month turns a new compliance burden into a ten-minute routine.
