Vendor W-9

Form W-9 is the IRS form used by a company to request your taxpayer identification number. Larimer County has created an electronic W-9 form for your convenience to keep your company information up to date with us. Please fill in all the fields in the W-9 form and press the "Email Form" button at the end of page 1 on this electronic form. By submitting a W-9, you are certifying that the tax ID number you are providing is correct and accurate. You are not required to sign the Certification (W-9 form), but you must provide your correct Name and TIN.

The W-9 information will be emailed to the Larimer County Accounts Payable Department. If you have any questions please call Finance at (970) 498-5940 or (970) 498-5937. Or you can fax the completed form to (970) 498-5942.
