Online travel agency tax compliance rests on three moving parts: the booking model that decides who is legally the seller, the economic nexus rules that decide which states can require collection, and the marketplace facilitator laws that pin the collection duty on the platform rather than the individual hotel or host. Get those right and the rest is process. Get them wrong across thousands of jurisdictions and the back taxes, interest, and penalties compound on every booking the platform ever facilitated.
How the Booking Model Decides Who Owes the Tax
Every OTA operates under one of two structures, and the choice controls tax liability more than any other factor.
In the merchant model, the platform buys room inventory at a negotiated wholesale rate, resells it to the traveler at a marked-up retail price, collects the full payment, keeps the spread, and sends the wholesale amount to the hotel. In the agency model, the hotel remains the merchant of record, the traveler pays at check-in, and the platform earns a commission without ever touching the room charge.
When the OTA is the merchant of record and processes the payment, most jurisdictions treat the platform as the party responsible for occupancy taxes. When the hotel collects payment directly, the hotel typically bears that duty and the OTA may only owe tax on its own commission or markup.
The harder question is what counts as the taxable base. Cities have argued that occupancy tax applies to the full retail price the traveler pays, including the OTA’s markup and service fees. Platforms have argued that only the wholesale rate paid to the hotel is a charge “for occupancy” and that the difference is compensation for a booking service. The Fifth Circuit held that a Texas hotel occupancy tax applied only to the discounted room rate the OTA paid to the hotel, not the higher amount the consumer paid to the platform.1Justia Law. City of San Antonio, Texas v. Hotels.com, L.P., No. 16-50479 Other jurisdictions define the taxable amount as the total price the guest pays, and several states have enacted statutes that specifically require OTAs to collect on the full retail charge including their margin. New York is one of them. A platform that applies one rule nationally will be wrong somewhere.
Economic Nexus After Wayfair
Before 2018, a jurisdiction generally needed the business to have a physical presence before it could require tax collection. The Supreme Court ended that in South Dakota v. Wayfair, Inc., holding that economic activity alone is enough.2Supreme Court of the United States. South Dakota v. Wayfair, Inc. The South Dakota statute the Court upheld set the trigger at $100,000 in annual sales or 200 separate transactions in the state.
Every state with a sales or use tax has since adopted some form of economic nexus. The $100,000 revenue figure is still the most common threshold. The transaction-count prong has been shrinking. South Dakota dropped its transaction count in 2023, and as of early 2026, roughly half the states that originally used one have eliminated it in favor of a dollar-volume standard alone. The rest still combine revenue with a transaction count in some form. New York sets a higher bar at $500,000 in sales combined with more than 100 transactions.
For a platform booking rooms in dozens of states, this is a monitoring problem. A jurisdiction that wasn’t on the radar in January may require registration by June because volume tipped over the threshold. Automated tax compliance software is effectively required at any meaningful scale; tracking revenue and transaction counts across thousands of jurisdictions by hand is not realistic.
Marketplace Facilitator Laws
Nearly every state with a sales tax has enacted marketplace facilitator legislation. These laws put the collection and remittance duty on the platform rather than on the individual hotel or property owner listing inventory. Auditing a handful of large platforms is easier for the state than chasing thousands of independent hosts.
Whether a platform counts as a facilitator turns on two elements: it provides a forum where sellers list inventory, and it processes the payment. A site that only advertises listings without handling the transaction is usually outside the definition. The distinguishing test is whether the platform knows a sale happened and at what price.
Once a platform meets the definition, it takes on full liability for tax it fails to collect or remit. Some states offer limited safe harbor for good-faith errors in the first year of collecting, but the protection is narrow and a pattern of undercollection will draw an audit. A platform generally cannot push the liability back to the property owner by contract. If the state’s facilitator law names the platform as the responsible party, the terms of service don’t override that.
What Counts as the Taxable Amount
The room rate is always taxable. Beyond that, jurisdictions split on the extras.
Mandatory surcharges like resort fees, destination fees, and amenity fees are increasingly treated as part of the occupancy tax base when they are tied to the right to occupy the room. Voluntary add-ons the guest can decline, such as spa credits or optional parking, are more commonly excluded. Cancellation fees and no-show charges are taxed in some states as a charge for a reserved room and treated in others as a penalty payment outside the tax base. There is no national rule, so a platform processing cancellations across multiple states may apply different treatments to the same type of charge.
The unresolved question in the merchant model is whether the OTA’s own markup is taxable. The Fifth Circuit excluded it under the Texas ordinances it reviewed. Statutes that define the taxable amount as the total consideration paid by the guest reach the opposite result.
Exemptions the Platform Has to Process
Not every booking is taxable, and exemption handling is where audit problems often start.
The most common exemption is for extended stays. A majority of jurisdictions exempt lodging from transient occupancy tax when the guest stays 30 or more consecutive days, on the theory that the stay resembles a residential lease at that point. Platforms that book both short and extended stays need to track the length of each reservation and either exempt qualifying bookings at the point of sale or refund tax once the stay crosses the threshold.
Federal Government Travelers
Federal employees on official business may be exempt from state and local lodging taxes depending on how the room is paid for. When lodging is charged to a centrally billed account through the GSA SmartPay program, the expense is paid directly by the federal government and should not be charged state taxes.3GSA SmartPay. GSA SmartPay Tax Advantage Travel Account Customer Guide Individually billed accounts, where the employee pays and seeks reimbursement, may or may not qualify depending on the state. Applying the right treatment usually means collecting the account type at booking.
Diplomatic Exemptions
Foreign diplomats and mission personnel may be exempt from hotel taxes if they present a valid diplomatic tax exemption card issued by the U.S. Department of State.4U.S. Department of State. Hotel Tax Exemption The exemption requires physical presentation of the card at payment. The State Department has said prepaid online bookings do not allow that verification, and it will not help obtain exemptions or reimbursements for taxes charged on internet purchases. Platforms that want to accommodate diplomatic exemptions typically need a manual review process or a direct-billing arrangement rather than standard online checkout.
1099-K Reporting for Payees
An OTA that processes payments to hotels and property owners is a third-party settlement organization under federal tax law, which triggers its own reporting duty separate from lodging tax. Under 26 U.S.C. ยง 6050W, a payment settlement entity must file Form 1099-K for each participating payee it settles reportable transactions with.5Office of the Law Revision Counsel. 26 USC 6050W – Returns Relating to Payments Made in Settlement of Payment Card and Third Party Network Transactions
The One Big Beautiful Bill Act retroactively reinstated the original thresholds. For 2026, a 1099-K is required only when payments to a single payee exceed $20,000 and the number of transactions exceeds 200.6Internal Revenue Service. IRS Issues FAQs on Form 1099-K Threshold Under the One, Big, Beautiful Bill Both conditions have to be met. A property owner who earns $25,000 through the platform on 150 bookings does not trigger a 1099-K.
Track gross payment amounts and transaction counts per payee whether or not the threshold is met, because the IRS can request documentation during an audit even when no form was filed. Forms must be furnished to payees by January 31 of the year following the calendar year in question.
Registration, Filing, and Records
Before collecting any lodging tax, an OTA has to register with the taxing authority in each jurisdiction where it has nexus. That usually starts with a state sales and use tax permit, which is free in most states. Some jurisdictions charge a nominal processing fee, and some may require a surety bond from remote sellers or high-volume platforms. Many cities and counties administer their own occupancy taxes separately, which means a second registration with the local finance or revenue office.
Registration is tied to when nexus is established. An OTA that crosses the threshold typically has 30 to 60 days to register and begin collecting. Failing to register does not cancel the obligation. It just means unremitted tax is piling up with interest.
Record-Keeping
For each booking, retain gross receipts, a breakdown of the room charge versus fees or markups, the duration of the stay, the property location, and the identity of the guest or exempt entity if an exemption was applied. Exemption certificates should be stored in a retrievable format and linked to the specific transaction.
The IRS recommends keeping federal tax records for at least three years, and up to seven years in situations involving bad debt deductions or unreported income above 25% of the return amount.7Internal Revenue Service. How Long Should I Keep Records State and local retention periods for lodging tax records fall in a similar range. Keeping everything for at least seven years is the safest approach and avoids tracking a different schedule for every jurisdiction.
Filing and Remittance
Most jurisdictions now require electronic filing through an online portal, with payment by ACH. Some smaller local offices still accept mailed checks, but electronic filing is increasingly mandatory above a certain volume. Filing frequency depends on tax collected: monthly for high-volume filers, quarterly or annually for lower-volume ones. Roughly half the states offer a small vendor compensation discount for filing and paying on time, typically 0.5% to 3% of the tax collected, sometimes capped at a monthly maximum.
Fixing Past Exposure Through Voluntary Disclosure
A platform that discovers it should have been collecting in a jurisdiction where it never registered has a choice: wait for an audit or come forward. The Multistate Tax Commission runs a Multistate Voluntary Disclosure Program that lets a business negotiate settlements in multiple states through one process, with the applicant’s identity kept confidential until an agreement is signed.8Multistate Tax Commission. Multistate Voluntary Disclosure Program
The trade-off in a voluntary disclosure agreement is direct. The business registers, files back returns, and pays the tax plus interest for a defined look-back period. In exchange, the state waives penalties and limits the look-back rather than reaching back to when the liability first arose. For sales and use taxes, the look-back is typically 36 to 60 months depending on the state.9Multistate Tax Commission. Lookback Periods for States Participating in National Nexus Program One caveat: if the platform actually collected tax from guests and did not remit it, most states will not waive penalties on that amount, and the look-back may extend to when collection began.
The window closes once a state contacts the business about an audit or assessment. After that, the leverage is gone and the full penalty structure applies.
Penalties for Getting It Wrong
Penalty structures vary, but the pattern is consistent: a percentage-based penalty on unpaid tax plus interest that runs from the original due date. Late filing penalties commonly range from 5% to 25% of tax owed, often escalating the longer a return goes unfiled. Interest is calculated separately and usually is not waivable, even when penalties get reduced through a settlement or voluntary disclosure.
The bigger exposure is failure to collect at all. If an OTA had a collection duty and never met it, the platform can be held liable for the full amount it should have collected from guests, even though that money was never withheld. The tax comes out of the platform’s own revenue. With interest running from each booking’s original due date, the cumulative liability across thousands of transactions in a single jurisdiction grows quickly. Repeated or willful noncompliance can also lead to license revocation or, in extreme cases, criminal referral for tax fraud.
