Identify the account and the tax
Federal employment alone does not exempt a traveler from every hotel tax. GSA SmartPay distinguishes centrally billed accounts, where the government is directly liable, from individually billed accounts, where the traveler is liable. A personal credit card does not carry the same exemption treatment as an eligible government payment method.
SmartPay explains that centrally billed transactions are exempt from direct state sales tax, while individually billed account treatment depends on state law. Gross receipts taxes imposed on a merchant and passed through to a customer require separate consideration; they are not automatically the same as a direct sales tax.
Check the state’s current requirements
Open the state travel tax directory, choose the hotel’s state and follow the linked official SmartPay and state taxation authority instructions. Confirm the account type, official-travel conditions, exemption form and required documentation. SmartPay’s directory concerns state sales tax and does not cover every county or municipal tax.
Before arrival, ask the hotel how it processes the applicable exemption and which documents it needs. Do not send a full card number through a public form or rate search. Resolve a disputed charge using the agency, merchant and state authority’s documented procedures.
Keep the room calculation separate
The CONUS room ceiling excludes lodging taxes. The travel calculator on this site also excludes those taxes and cannot decide whether an individual traveler qualifies for an exemption. Keep the itemized bill so eligible room charges, exempted taxes and any remaining taxes can be identified separately.
No state is labeled tax-free in this directory. The relevant rules depend on the kind of tax, payment arrangement and documentation, and can change independently of the annual per diem rate.
