TL;DR — Setting up a trading business for tax benefits is complex, as the IRS doesn't explicitly define a 'trader' and can scrutinize Schedule C filings with losses. A more robust approach involves establishing a family office structure with a management company (often a C-corp or LLC taxed as one) and a partnership for trading activities to gain asset protection and tax advantages.
Takeaway — Structuring your trading activities through a dedicated entity like a family office management company and partnership provides superior tax benefits and asset protection compared to claiming deductions as an individual sole proprietor.
