3 . Renew online through the California DMV website: The California DMV does have an option for you to renew your motor vehicle tags online. Their website has the capability to allow its customers to log-in to their website and renew the registration online. Again, like any service the California DMV offers directly, there is no fee. However, their service is NOT instant. They will collect your money instantly, but the sticker is not issued right away. In addition, you have to have an email, create a username and a password, and provide private information (driver’s license, address information). The registration process can be a pain. Here’s the link to their online portal: DMV online portal.
