Current Mileage Reimbursement Rate 2026 in California: What You Need to Know

If you drive your personal vehicle for work in California, keeping track of the current mileage reimbursement rates is essential for maximizing your tax deductions or ensuring fair compensation from your employer. For 2026, the Internal Revenue Service (IRS) and California state guidelines have updated the standard mileage rates to reflect the changing costs of operating a vehicle, including fuel, insurance, and maintenance.

2026 Mileage Rates at a Glance

Whether you are an independent contractor, a small business owner, or a state employee (CalHR standard), these are the official per-mile rates you should use for the 2026 tax year.

Driving Purpose	2026 Rate (Per Mile)	Change from 2025
Business Use	72.5 cents ($0.725)	+ 2.5 cents
Medical / Relocation*	20.5 cents ($0.205)	– 0.5 cents
Charitable Work	14 cents ($0.14)	Unchanged (Set by statute)

*Note: The relocation/moving deduction is generally limited to active-duty military and certain intelligence community members under current federal law, though it is also the standard rate used by the State of California (CalHR) for reimbursing state employee relocations.

How California Employers Handle Mileage Reimbursement

California labor laws are notoriously strict when it comes to employee expenses. Under California Labor Code Section 2802, employers are legally required to indemnify employees for all necessary business expenses. This includes the cost of using a personal vehicle for work-related duties (such as driving to client meetings, running business errands, or traveling between job sites).

• The IRS Rate as a Safe Harbor: Most California employers choose to reimburse employees at the IRS standard rate of 72.5 cents per mile. Doing so creates a “safe harbor,” meaning the state generally presumes this rate sufficiently covers fuel, wear and tear, insurance, and depreciation.
• Tax-Free Reimbursements: If your employer reimburses you at exactly 72.5 cents per mile (or less), this money is not considered taxable income. It will not be subject to income tax or payroll taxes.
• Reimbursements Above the IRS Rate: Employers are allowed to reimburse at a higher rate if they choose. However, any amount paid above the 72.5 cents per mile threshold is considered taxable income and must be reported on your W-2.

How to Calculate Your 2026 Mileage Reimbursement

Calculating your reimbursement or tax deduction is simple if you keep a compliant mileage log. Your log must include the date, the destination, the business purpose, and the total miles driven for each trip.

The Formula:
Total Business Miles Driven × $0.725 = Your Reimbursement / Deduction

Example: If you drive 1,500 miles for business purposes in California during 2026, your calculation would be:
1,500 miles × $0.725 = $1,087.50.

Frequently Asked Questions (FAQ)

Does the 72.5-cent rate apply to electric vehicles (EVs)?

Yes. The IRS standard mileage rate applies equally to fully electric vehicles (EVs), hybrids, diesel-powered vehicles, and traditional gasoline cars. You do not get a different rate based on what type of engine your car has.

Can my employer pay me less than the IRS rate in California?

Technically, yes, but it is risky for the employer. If an employer pays less than 72.5 cents per mile, they must be prepared to prove that the lower amount fully covers the employee’s actual vehicle expenses. If it does not, the employer is in violation of California Labor Code 2802.

Do I claim mileage if I lease my car?

Yes, but there is a catch. If you choose to use the standard mileage rate for a leased vehicle, you must use that method for the entire duration of the lease period (including renewals). You cannot switch back and forth between the standard mileage rate and the “actual expenses” method.
