Answer:
January 1, 2020
Step-by-step explanation:
An S corporation isalso called small business corporation. It is a type of company that shields its owners in the case of liabilities. The owners are not directly liable for obligations of the corporation.
A calenders year of a company is defined as the fiscal year in which a company makes profit and declares a profit or loss within that time frame.
If shareholders file a revocation statement on March 20, 2019, to terminate their S corporation's S election, they will have to wait till the end of the fiscal year before the S corporation is terminated.
That is on January 1, 2020.
