Crowdfunding in Equity Investment - Tax Implications?

[Ronald Thompson]

I am told that when investing in crowdfunding equity investments, you are issued a K1 document at the end of the year for taxes.

What are the tax implications when investing with taxable money vs money from a SDIRA?

Are the returns considered income or dividend?

When the project is cashed out at the projected 5 -7 years (typical of most offerings), is that considered income, dividend or capital gains?

I would prefer to use my SDIRA but wanted to see if there would be argument to use taxable money.

Thanks
