C Corp established in 2019, last corp tax return filed in 2020, corp dissolution filed in 2023.
2500 shares at $1 per share issued. 

The client lost over $100,000 of his investment over 3 years. No additional shares were issued when new funds were invested in the 3 year period. No income was generated in any of the years the corporation existed. They were primarily in a research and development stage. Can he claim a loss? If so, which IRC do they qualify for?
