Hello, This is your Green Grosser helping you gross green today. Now, we are discussing treasury bills of t-bills. Treasury bills are short-term debt obligations of one year or less that are issued with the full faith and credit of the U.S. Treasury, making them the most secure debt investment available. The maturity dates for T-bills are usually 91 or 182 days, or 52 weeks. There is no interest paid prior to maturity, therefore all taxes on the interest are paid the year following maturity. T-bills are bought at a discount. As a result, their interest is the difference between the purchase price of the security and what you receive at maturity. T-bills can be bought at any one of the twelve federal reserve banks across the country or they can be bought at the secondary market from a bank or a brokerage firm. T-bills are sold to the institutions in one million dollar round lots, but the public can buy them in lots as little as on thousand dollars apiece in the secondary market. Furthermore, T-bills are exempt from all state and local  income taxes and have instant liquidity. The only difference between t-bills, bonds, and notes is the length of maturity, with treasury bills being the shortest.
