I have a one member LLC that operates as an investment group. We pool outside capital from our members and trade securities. I am wondering how i should file taxes??

If this is a single-member LLC (you are the sole owner), then you will file the information for that LLC on your personal income tax return using Schedule C (Self-employed profit and loss). To input your Schedule C LLC activity:

• Sign in to your account and click on the orange Take me to my return button (skip this step if you are already in your return)
• Click on federal>wages and income>all income>Self-Employment
• Self-employment income and expenses>start
• TurboTax will walk you through inputting your business profile>your business income and expenses

"We pool outside capital from our members and trade securities"

I agree with @DaveF1006 with respect to your taxes (i.e., single-member LLCs are disregarded).

However,  if you are pooling your funds with other LLC owners, individuals, et al, with an agreement to split profits/losses from investments or trades, then that sounds more like a partnership than anything else.

The foregoing begs the question as to whose taxpayer ID number is on the tax reporting statements (presumably a 1099-B). You might want to seek professional guidance for this scenario to ensure all aspects comport with the arrangement you have with other members of the "group".
