My wife and I are good savers. We're able to put away about $3500 monthly. We allow this money to accumulate in an ordinary money market fund until the end of the year. From the accumulation we pay the property taxes, insurance premiums and fund the IRAs and our son's Coverdell account. We fully fund the IRAs each year and adjust our unmatched contributions to the 403(b)s just enough to reduce our AGI to make the IRAs possible. My wife is eligible for California's CalSTRS retirement as well has her 403(b) and Roth IRA and I will receive Social Security as well as the 403(b) and Roth IRA. We try to keep about $30,000 in cash in the money market fund, but I think it's too much, given our monthly salaries. We're contemplating one of two alternatives for the "extra" cash and would appreciate anyone's thinking on them.
First, among our account types (traditional IRAs, Roth IRAs, 403(b)s, taxable mutual funds, etc.) we don't have much in the way of federally insured deposits. Everything's in mutual funds except for our everyday checking and savings accounts at the credit union. We could establish a sort of monthly deposit "ladder" of CD's with one of those online banks, depositing $1,000 each month in a new CD, so we'll have a maturing, federally insured cash account available each month. We could roll these over or take them as "income".
For a second idea, we could regularly invest in a municipal bond fund, exempt from U.S. and California income taxes. I haven't yet penciled this out, but our Federal Tax Rate for 2007 was 25%, so it might be worthwhile. What do you think?
