I live in Ohio. In Ohio, you can renew your car tags for up to 5 years via e-mail - unless you want amateur radio tags. Then you can only renew for 1 year and if your currently-paid end date is more than a year out, you have to give up the funds already paid. In my case, my ham license expires in 2029, but I can only get car tags for 1 year and I have to go in and show the BMV my FCC license each year upon renewal. I am debating whether the ham tag is worth the hassle. How do ham tags/amateur radio tags work in your state?
