If you are a W-2 employee, nothing is deductible. You may want to discuss your situation with your employer.
If you are self-employed as an independent contractor and file a schedule C, the definition of commuting, regular place of work, and what mileage is deductible, are covered in IRS Publication 463 in chapter 4.

You can use the standard mileage method or the exact expense method, but not both. The standard mileage method is more advantageous for most taxpayers.
