Tax Implications - Trader Vs Investor, page-7

I believe one of the differences is that traders need to treat the cost of brokerage as an expense while investors include the cost of buying and selling as capital costs. This means that for investors brokerage (both buy and sell) is recognised for tax purposes as part of the asset sale and not disclosed separately, and not in the year of purchase. Traders on the other hand claim it as an expense in the year the actual buy or sell occurred.
