I agree with the majority of posters. ML can't make money off of you as it stands.
I use CapitolONE 360, but IL taxes interest income @ 5%. I only have 50K there, now, but I also keep 150K I moved into Six individual 6 month Treasury bills. States don't tax interest from Them. I use 26 week (6 month) T-Bills in 25K increments, so they roll over monthly. I can set it up to roll over 4 times max (just started last summer), but I can intervene and stop it if needed.
T-Bills are purchased below value and upon rollover, the interest is deposited back into CapitolONE 360, so the next 25K T-Bill costs about $24,800. I set my TreasuryDirect account to use my online savings, and it took about 10 minutes to set one up online.
Either way, You sound intelligent enough to do it yourself. No one looks after you and your wishes better than you, and your significant other.
