Yes, you have to file IRS Form 1120S even if you had no income or expenses.
The Form 1120S Income Tax Return is due March 15, 2016.
Under the tax code, every U.S. corporation that's in business to make a profit must file a tax return regardless of whether it made any money. This applies both to traditional corporations and Subchapter S corporations.
If you fail to file Form 1120S, the late-filing penalty is more expensive. For each month the return is late, the monthly penalty is $195 multiplied by the number of shareholders.
