re: Minimizing Tax Bill

You can use I bonds as an emergency savings vehicle. No tax on interest until maturity. Don't go crazy on savings you are likely getting taxed on interest at your marginal tax rate plus a surcharge of 3.8 percent and state taxes so if you have excess savings you might as well use it for something you need or want or find a tax deferred vehicle that is not so hard to get to for the larger amounts of cash. I had over 4 K in interest on savings and got hit this way this year. Will use a chunk for a new roof and HVAC system in the next year or two.
