As part of a comprehensive effort to streamline processes for our permit holders and the regulated community, the EAA now offers an online payment program that allows individuals and business entities to pay for their transactions by credit card (American Express, Discover, MasterCard, or VISA) or by electronic check.
The payment site is operated and maintained by a secure, third party, payment processor. A convenience fee of 2.75% applies to all credit card transactions (a $2 minimum fee) and a $2.00 fee applies to e-check transactions. The EAA does not keep any portion of these convenience fees. After confirmation of payment, the EAA will coordinate internally to ensure your payment is posted to the correct account. This process may take up to 72 hours.
