How do I use investments to lower my taxes [US]?
Consider the individual who pays $1,000,000 in taxes.  His/her income must be substantial.  That is what one should aim for.  Investments for the most part, do not lower ones taxes.   In one of John Grisham's novels, tax shelters are being discussed.  Sorry, I do not remember which book.  The discussion goes something like this: There are a few investments which can lower your taxes.  Purchase a house.  Mortgage interest on your principle residence is deductible (if you itemize deductions).  If you don't itemize, focus on increasing income to the point where itemizing benefits you. In general, businesses have more deductions than individuals.  Own a small business. You (or your accountant) will discover many deductions.  Hint: the company should lease a car/truck, many meals are now deductible.  This is not the reason to own a business.
