Internal Revenue Service tax laws. On our site you will find reference links to the taxing authority sites and regulations. JPL endeavors to simplify the process while managing compliance. Questions about the JPL tax reporting and withholding process should be directed to the JPL Subcontract Manager for your PO or Subcontract. Tax advice cannot be provided by JPL and supplier compliance or exemption questions should be referred to the supplier’s tax preparer.
