Optional Service for Setting Up Automatic Premium Payment (EFT/ACH)
Good news: You may elect an automatic premium payment option so that your premium amount will automatically be withdrawn from your bank account via Electronic Funds Transfer (EFT/ACH) on a monthly basis. This convenient payment option ensures timely receipt of your monthly premium payments. If you choose this automatic payment service, you will not need to send a monthly premium check to Mercer after this service is set-up. To avoid late payments or lapsed coverage, set up auto-pay today at www.mercermyaccount.com or click on My Account in the upper right corner of the page.

Understanding your Caltech Retiree Service Center Monthly Billing Notice
All monthly bills generate the first Saturday of each month for the next month’s premium due. Below is an example of how the billing process works:
- The bill for October premium is generated on the 1st Saturday in September and payment will be due October 1.
- If full payment is not received by the October premium due date, 10/1, a second billing notice generates on the 1st Saturday in October. This billing notice will include the November premium amount in addition to the October amount due.
- October’s premium payment must be received by The Caltech Retiree Service Center no later than October 31st in order to keep coverage active.
