1. Keep filing your annual stuff in Delaware. 2. Don't forget to keep paying your resident agent in Delaware. 3. You undoubtedly registered your Delaware corporation in your home State because you're doing business there. Keep up to date with the annual filings there. 4. Very important: keep filing tax returns. Even if you have zero income. Two reasons. (1) It is required. Corporations file even with zero income, unlike humans. (2) Your corporation is spending money (see items 1 - 3 above) so you might as well make a little tax loss that you can use to shelter future profits. 5. Talk to your CPA about other peculiarities specific to you. E.g., sales tax returns if you've been filing them. E.g., payroll tax returns. E.g., local business license. In all of these cases, if you are just hibernating for a year it is easier to keep filing stuff with zero written on it than to log out of the system for a year then log back in.
