Vendor Payments

State agencies go to Vendor Registry – Paying Suppliers for assistance in setting up payments to vendors (suppliers).

Vendor (supplier or individual) On-line Registration

New vendors (suppliers and individuals) looking to receive payment from the state should use our on-line supplier registration pages to "Register as a Supplier".  The registration process consists of five short pages which allow the vendor to provide necessary information to the Vendor Registry Office.  All registrations will require the appropriate US W-9 or Foreign W-8 form be submitted, choose the correct form below. All supplier registrations will be reviewed and go through the approval process of the Vendor Registry Office.

Payee (Vendor) Forms for US Individuals, Businesses, and Political Subdivisions

Payee (Vendor) Forms for Foreign (non US) Individuals, Businesses and Political Subdivisions

Generally, 30% must be withheld 30% from the gross amount paid to a foreign payee unless you can reliably associate the payment with valid documentation that establishes either of the following.

  1. The payee is a US person.
  2. The payee is a foreign person that is the beneficial owner of the income and is entitled to a reduced rate of withholding. View the IRS recommendation about obtaining proper documentation before making a payment. 

The IRS supplies four different W-8 forms to certify foreign status. Select the appropriate form for your type of business:

  • Certificate of Foreign Status of Beneficial Owner for US Tax Withholding (Individuals) IRS Form W-8BEN. Payees outside of the US do not need a US taxpayer ID to complete this form. IRS instructions on completing form.
