40 year old A and J makes 1M a year. What is the best investment to save on tax?
There is nothing legal you can do in the United States to avoid the tax burden of income earned as an employee other than offsetting it with pre-tax contributions (which it sounds like you're already doing), making charitable contributions, or incurring investment losses (which is cutting off your nose to spite your face).  So that $660K can't be helped. As for the $80K in stock dividends, you could move those investments into "growth" companies rather than "value" companies.  Growth companies are those that pay less in dividends, where the primary increase in wealth occurs only in share price increase.  This puts off your tax bill until you finally sell your shares, and (depending on how the tax laws are at that time) your tax bill will be lower on those capital gains than they are currently on these dividends. Regarding rental income I know nothing, but I think you're entitled to depreciate your property's value over time and count that against the taxes you owe on the rents.  And you can deduct all the upkeep expenses.  As with employment income, intentionally incurring rental losses to lower your tax bill is not logical:  for every dollar you earn, you only have to give about 50 cents to the government, whereas for every dollar you lose, you've lost a dollar.
