You certainly can do this on line. However, you cannot do both at the same time. After you renew your license, close out of that window and log off the internet. Then log back on, clear your browser and log onto the site again and it should allow you to renew your permit. (BTW you can only use Visa or MC for this. They will not accept checks via mail). Also, if you get to a question asking whether you have obtained your surity bond or not, answer yes whether you have or not. If you don't, that will set off a chain reaction that will cause you to have to contact the DCA and delay your business permit for about 2 months.
