With some smart manœuvres, you can reduce taxes substantially through your spouse. This works especially if you are in the highest tax bracket and your significant other does not have a taxable income.
At the risk of being labelled a chauvinist, let us assume (only for the sake of argument), that the wife stays home and the husband earns.
First, let's do some ground work. Let's say there are two separate joint accounts, one for husband/ wife and the other for the wife/ husband. Bear with me if this sounds pointless to you right now. But it is important!
