Summary
Short-term rental operators in unincorporated Orange County must collect a 10 percent Transient Occupancy Tax on rent, register with the Tax Administrator within 30 days, and file quarterly tax returns.
For the privilege of occupancy in any hotel, each transient is subject to and shall pay a tax in the amount of ten (10) percent of the rent charged by the operator. Said tax constitutes a debt owed by the transient to the County which is extinguished only by payment to the operator or to the County. The transient shall pay the tax to the operator of the hotel at the time rent is paid.

Full Breakdown
Orange County's Uniform Transient Occupancy Tax Ordinance (Sec. 1-4-119 et seq.) taxes "transient" occupancy of 30 days or less in any "hotel": a term broad enough to cover short-term rental houses, since the only exemption covers a dwelling rented "only occasionally and incidentally" to the owner's normal use, which a regularly booked rental doesn't meet. Operators must register for a Transient Occupancy Registration Certificate within 30 days of starting business, collect 10 percent of the rent from each guest, and remit it quarterly to the Tax Administrator (the County Tax Collector). Applies only in unincorporated areas; incorporated cities set their own TOT rates.
Violations & Fines
Late remittance draws a 10% delinquency penalty, a second 10% penalty after 30 more days, 25% for fraud, and 1.5% monthly interest; willful violations (failure to register, false returns) are a misdemeanor punishable by up to $1,000 and 6 months in jail.
