I am the office administrator for a small cyber startup. We are organized as a C-corporation. My CEO has asked me to investigate 1120S filing and what other end of year forms we may need to file. (10K? 8K?) I am certain we need to file an 1120 but unsure of the others.

As a C corporation, you will file a Form 1120 for the company's federal return, plus the applicable state corporate tax returns for the states in which the company operates.

 

If there was an S election made and the company is‌ classified as an S corporation for tax purposes, you'd file a Form 1120S. 

 

Forms 8K and 10K aren't tax-related forms. They are used by publicly traded companies to report certain financial results and significant events to shareholders.
