Your franchise taxes owed to the state of Delaware will continue to accrue until you dissolve the corporation but there currently are no legal penalties for outstanding or delinquent franchise taxes owed to Delaware, so in theory you can do nothing and you will just continue to rack up taxes and tax penalties (monetary). But the corporation cannot be dissolved until all franchise taxes are paid and current. If they change their laws in the future, however, they may be able to seek legal prosecution. I know this because I am in the same situation, and I recently spoke to the Delaware Division of Corporations.
