C-corp to S-corp

[Questionguy101]

A C-corp elected to become a S-corp. The S-corp will keep the same EIN of the C-corp. Is the 'last' tax return of the C-corp considered a 'final' tax return? Should we check the 'final' box in the last tax return of the C-corp?

You

are not terminating the corporation, just changing the way the income is taxed.
