Traveling for business in California? Understanding per diem rates is essential for managing expenses effectively, whether you're an employee, an accountant, or a small business owner. California, known for its diverse geography and varying costs of living from bustling cities like Los Angeles and San Francisco to quieter regions, has specific considerations when it comes to travel allowances.
Per diem – a daily allowance for lodging, meals, and incidental expenses (M&IE) – helps standardize reimbursements and ensure travelers are adequately compensated without excessive administrative burden. This guide will walk you through California per diem rates, how to calculate them, relevant laws, and how technology can simplify the entire process.
California Per Diem Rates
For official government travel, per diem rates in California are generally established by the U.S. General Services Administration (GSA). These rates are the maximum allowances federal employees are reimbursed for expenses incurred while on official travel within the state. California does not have its own separate state-wide per diem schedule that supersedes these GSA rates for general employment purposes.
Key aspects of GSA per diem rates applicable in California include:
- Location-Specific Rates: Rates vary significantly by county and sometimes even by city within California. Areas with a higher cost of living, designated as Non-Standard Areas (NSAs), will have higher per diem rates than the standard CONUS (Continental United States) rate. You can find the current GSA per diem rates for specific locations in California using the calculator below or by visiting the official GSA website. For FY 2025 (October 1, 2024 - September 30, 2025), the standard CONUS rate is $178 ($110 lodging, $68 M&IE), but many locations in California will have higher NSA rates.
- Seasonal Variations: In some California locations, especially tourist destinations, lodging per diem rates can change based on the season to reflect fluctuations in hotel costs.
- Components: Each per diem rate consists of two main parts:
- Maximum Lodging Allowance: The maximum amount reimbursable for nightly accommodation. This excludes taxes on lodging in CONUS locations, which can be claimed separately.
- Meals and Incidental Expenses (M&IE): A set daily amount for meals and incidental costs (like tips for hotel staff). The M&IE rate includes taxes and tips for meals.
- First and Last Day of Travel: On the first and last day of travel, employees receive 75% of the total M&IE rate for their temporary duty location.
- IRS High-Cost Localities: For federal tax substantiation purposes using the high-low method, the IRS (in Notice N-24-68, effective Oct 1, 2024) identifies several California locations as "high-cost," including Los Angeles, San Francisco, San Diego, Napa, and Yosemite National Park, among others. While these IRS rates ($319 for high-cost, $225 for other localities in FY2025) are for a specific tax reporting method, they underscore the recognized high expense levels in these areas.
It's important to note that while private employers in California are not mandated to use GSA rates, many use them as a benchmark for their travel reimbursement policies.
Some specific state programs or agencies, like the one referenced in a document from the California Office of Historic Preservation (OHP), might cite specific federal per diem schedules for their participants, which could differ from current general GSA rates or have unique provisions for unlisted counties within their specific context. Always refer to your organization's travel policy for definitive guidance.
