I'll betcha if you type that same exact question into Google, you'd find your answer.

Yes, you have to file a return even if there is no income, expenses, or business activity during the year. As long as the S-corp election is in effect, an annual return is required.

Failure to file can result in hefty monthly penalties for each shareholder.

If the company is permanently closing, file a final return and formally dissolve the entity.
