Payments made using ACH (e-check) are directly withdrawn from your checking account and incur no additional charges. Payments made using a credit card will incur an additional convenience charge that is paid to the credit card processor, not the City of West Allis. The customer assumes full responsibility for all online transactions and no warranty or guarantee is given by the City of West Allis for online payment transactions. Online payments are processed by outside agencies, not the City West Allis, and you will be redirected to another site to make your online payment. Some anti-virus programs may block this redirection to another site, and you may need to disable pop-up blocking to be able to make a payment. If you require a payment receipt, print the confirmation page after completing your transaction. Payment information on the City of West Allis site will be updated within 3 business days after your online payment is made. Warning: Online payments after 8:00 am usually take 3 business days to be credited to your account. The payments are credited when the funds are deposited in the City’s account.
