Tim, if I have 100% of the household income as my wife is a stay at home Mom, and I want to invest leveraged money from our joint Secured LOC, paying all interest costs with dividend income earned from the investments, am I better off  setting up the account in my wife's name solely and all income and costs go to her, or splitting the account by making it joint ownership, or "lending" her the money from our HELOC at the prescribed rate?   For reference, last year's dividend income from this was $10K, Interest cost of $8K and capital gains of $20K. 

My marginal tax rate is at the max - my wife's net income is typcally $0.
