Doing Business with the City of Issaquah
Accounts Payable
The accounts payable function is responsible for issuing payment for all city bills. The City of Issaquah is committed to the timely and accurate processing of all vendor payments.

Vendor Requirements
As required by the Internal Revenue Service all vendors must have a current form W-9 on file with the city. The form must be filled out completely and mailed to the above address. Failure to comply may result in backup withholding or payment of invoices to be delayed until the W-9 is returned.

A completed City of Issaquah W-9 form is also available for those companies making payments to the City.

Lost Check
The city mails its payments via the United States Postal Service. If for some reason, a city issued check is lost or missing, a duplicate check can be issued by having an affidavit filed with the city. Please complete the Affidavit Form, have your signature notarized and return it to the following address:
City of Issaquah
Attn: Accounts Payable
P.O. Box 1307
Issaquah, WA 98027-1307

Once this notarized affidavit is received at our office, a new check will be sent to you.
