If I am investing my income into stocks or options, is that tax deductible? If so, how does it work?

The purchase of an asset is not a taxable event. But selling that asset is and must be reported as well as any income produced by that asset unless specifically tax exempt.

Hey, no deduction for putting your money into the Stock Market.
