Calculate California's per diem allowance for your business travel

California

Per diem rates simplify business travel expenses by providing standardized reimbursement amounts for lodging, meals, and incidental expenses. They help ensure fair compensation for employees and allow employers to control costs.

Understanding California's per diem rates is essential, especially since travel expenses can vary significantly across different cities and regions within the state. Clear per diem guidelines make expense reporting easier and help companies comply with federal regulations.

California per diem rates

For areas without specific per diem rates, California defaults to standard allowances: $110 per night for lodging and $68 daily for meals and incidentals. Set by the General Services Administration (GSA), these rates are the baseline for expense reimbursements.

However, some cities warrant higher or lower allowances, such as San Diego, San Francisco and Los Angeles to match their local living costs. Here's how the rates compare:
