A Treasury bill bought directly from the federal government through TreasuryDirect carries no sales commission and no advisory fee, a structural difference from buying the same bill through a bank or brokerage account. The interest a bill pays, technically the discount between what an investor pays and the face value received at maturity, is also exempt from state and local income tax everywhere in the country, even though it remains fully taxable at the federal level.
Why the Direct Route Skips a Fee Entirely
Treasury bills are short-term federal debt, sold in terms ranging from four weeks to 52 weeks, and TreasuryDirect is the government’s own platform for buying them without an intermediary. Because the purchase happens directly between the investor and the Treasury, there is no broker spread, commission, or account maintenance charge built into the transaction the way there often is when the same security is held inside a brokerage sweep account. A bank, brokerage, or dealer offering the same bill typically adds a markup or fee for the convenience of holding it in an existing account, an expense that eats into the small margin a short-term bill already offers.
TreasuryDirect draws that distinction explicitly on its page for buying a marketable security, describing the platform as a no-fee channel maintained by the Treasury for individual investors. The minimum purchase through TreasuryDirect is $100, and bids are placed noncompetitively, meaning the buyer is guaranteed the full amount requested at the rate set by that auction rather than having to guess a yield in advance. A single buyer may purchase up to $10 million of a given bill in one auction using the noncompetitive method, though most individual retail purchases fall far below that ceiling.

How the Auction Calendar Works
Treasury bills are not sold continuously; they move through a recurring auction cycle. The 13-week and 26-week bills are offered every week, with the Treasury announcing the offering on Thursday, holding the auction the following Monday, and issuing the bill on the Thursday after that. The 17-week bill follows a similar weekly pattern, announced Tuesday and auctioned Wednesday, while the 52-week bill is auctioned only once every four weeks, according to the schedule TreasuryDirect maintains on its page for when auctions happen. An investor who wants a bill maturing on a specific date needs to place an order before the relevant auction deadline rather than buying on demand the way a stock is purchased.
Once purchased through TreasuryDirect, a security generally must sit in the account for a minimum holding period before it can be sold or transferred, which effectively means very short bills, such as the four-week term, are held to maturity rather than traded.
The State Tax Exemption and How It Is Reported
The interest earned on a Treasury bill, note, bond, or TIPS is subject to federal income tax but exempt from state and local income tax, a rule that applies automatically without any special election. TreasuryDirect’s page on tax forms and withholding confirms that a 1099-INT is issued each January showing the interest earned, and that figure is reported on the federal return while being excluded from the state return. For a retiree living in a state that taxes ordinary income, that exemption can make a Treasury bill’s after-tax yield higher than a bank CD advertising the same headline rate, since the CD’s interest is typically taxed by both the federal government and the state.
Withholding is handled differently than with a bank account as well. TreasuryDirect does not automatically withhold federal tax from Treasury bill interest unless a holder specifically elects withholding on the account, which means a household relying heavily on bill income for cash flow needs to plan for that tax liability separately, often through estimated quarterly payments, rather than assuming a portion is set aside automatically the way an employer withholds from a paycheck.
How Bill Yields Compare With Bank CDs and Money Markets
A bank certificate of deposit and a money market account both compete with Treasury bills for the same short-term cash, and the comparison is not simply about which one advertises the higher rate. Because bill interest is exempt from state and local tax while a CD’s interest is not, two products with identical advertised yields can produce different amounts of spendable money once April arrives, with the gap widening in states that impose higher income tax rates. Bank products also carry FDIC insurance up to standard limits per depositor per institution, while Treasury bills carry the backing of the federal government directly, a different form of safety that does not depend on any single bank’s financial condition.
Liquidity is the other side of the tradeoff. A money market account or savings account can typically be accessed within a day or two at any point, while a Treasury bill purchased through TreasuryDirect is designed to be held to its stated maturity date, whether that is four weeks or a full year out. A household that expects to need part of its cash on short notice generally keeps some money in a more liquid account and reserves bill purchases for money that can wait for a known maturity date.
What a Retiree Weighs Before Buying
Because Treasury bills mature quickly, often in a matter of weeks rather than years, they function less like a long-term investment and more like a place to park cash that will be needed within the coming months. The tradeoff for that flexibility and the state tax break is that the return moves with each new auction; a bill bought at one auction will not necessarily reinvest at the same rate when it matures and the proceeds are rolled into a new one. A household drawing down savings in retirement can ladder multiple bill maturities, TreasuryDirect’s own materials on Treasury bills note, so that a portion of the money comes due every few weeks or months rather than all at once.
Setting up a TreasuryDirect account takes longer than opening a brokerage sweep account, and funds move by direct bank debit rather than a same-day transfer, both details worth planning around before an auction deadline arrives.
