Summary

Short-term rental operators in San Ramon owe Transient Occupancy Tax on every booking, but Municipal Code section D4-27.D.9 credits any TOT a hosting website already collected and paid to the city under its own agreement. Operators pay only the balance, and platforms without such an agreement leave the full obligation on the operator.

The Operator shall register with the City for the collection and remittance of Transient Occupancy Taxes (TOT) associated with the operation of the short-term rental. The Operator shall be responsible for annual payments of TOT less any TOT payments collected by host websites which are subject to a separate agreement with the City.

Full Breakdown

9 states: "The Operator shall register with the City for the collection and remittance of Transient Occupancy Taxes (TOT) associated with the operation of the short-term rental. 1. It makes the operator the default taxpayer of record: registration for TOT collection is mandatory, and annual payment is owed on the rent charged for the stay. The credit applies only where the hosting platform has struck its own separate agreement directly with the City of San Ramon to collect and remit TOT; absent such an agreement, the platform's collection of guest funds does not reduce what the operator personally owes the Finance Department.

Because the credit is conditioned on a platform-specific deal rather than a blanket exemption, an operator using a platform with no agreement in place must still register for and pay TOT directly, even if that platform separately charges guests an occupancy-tax line item. 10, and the annual renewal and TOT reporting run on the registration's own calendar, not the platform's billing cycle.

Violations & Fines

An operator who under-reports TOT by wrongly assuming a platform's collection satisfies the full obligation is liable for the shortfall to the Finance Department. Enforcement follows Title B of the Municipal Code, and unresolved short-term rental violations can trigger the D4-27.G revocation hearing before the Zoning Administrator.

Frequently Asked Questions

Does Airbnb pay my San Ramon transient occupancy tax for me?
Only if that platform has its own separate agreement with the City to collect and remit TOT. Section D4-27.D.9 lets an operator subtract TOT a platform already paid under such a deal; without one, the operator owes the full amount.
Who is responsible for San Ramon's short-term rental tax if the platform collects it?
The Operator remains registered and responsible for annual TOT payments. Section D4-27.D.9 only reduces what is owed by whatever the host website separately remitted under its own City agreement, it does not shift the underlying liability.
What if my booking platform has no agreement with San Ramon?
Then nothing the platform collects offsets your TOT bill. You must register and pay the full Transient Occupancy Tax on the rental yourself under D4-27.D.9.
