As a Koch company vendor who has submitted an invoice or signed contract, we are required by United States Internal Revenue Service regulations to obtain additional documentation for our files before an invoice can be properly processed.

It is important to note that this documentation will not be filed with the US IRS. This documentation is for our files in the event of an audit by the IRS as proof of proper withholding. If we do not receive the proper documentation, the IRS requires us to withhold tax at the maximum rate (up to 30 percent) on any dividend, interest or other income on US securities paid to your account.
