An individual investor in 2026 has two real ways to buy U.S. Treasuries directly. TreasuryDirect, the website run by the Treasury Department, and any major brokerage like Fidelity, Schwab, or Vanguard. Both work. Both are safe. They serve different goals, and the right answer depends on what you are trying to do, not on which one is technically better.
TreasuryDirect is the government's direct platform. You buy bills, notes, bonds, TIPS, and Series I Bonds directly from the Treasury at auction. There are no fees. The interface looks like it was built in 2003 because it was, and it has not changed much since. Account creation requires linking a bank account and going through identity verification. The transfers between TreasuryDirect and your bank take one to three business days each way.
Brokerages let you buy the same Treasuries on the secondary market or through new-issue auctions. Fidelity, Schwab, and Vanguard charge zero commission on Treasury purchases. The interfaces are clean. The trades settle inside your normal brokerage account. You can hold Treasuries next to your stocks and ETFs in the same dashboard, sell them quickly if you need cash, and reinvest the proceeds without moving money between accounts.
The case for TreasuryDirect is narrow but real. Series I Bonds are only available through TreasuryDirect. There is a $10,000 annual purchase limit per person plus an additional $5,000 if you use your tax refund. If you want I Bonds, you have no choice but to use the platform. For everything else, the case for TreasuryDirect is mostly philosophical, that you prefer to hold the bond directly with the Treasury rather than through a brokerage intermediary.
The case for a brokerage is much broader. Liquidity is real and matters. A T-bill held in a brokerage can be sold the same day if you need the cash. A T-bill held in TreasuryDirect can also be transferred but the process is slower and clunkier. If you are building a Treasury ladder, brokerage tools at Fidelity and Schwab let you build the ladder visually, see the maturity dates lined up, and set up automatic reinvestment of maturing rungs.
For most investors, the cleanest setup is to use a brokerage for the operational work and TreasuryDirect only for I Bonds. Buy bills, notes, and TIPS through your brokerage. Build the ladder there. Reinvest there. Use TreasuryDirect once a year to put $10,000 into I Bonds and let it sit until inflation rates drop or you need the money. That split gives you the flexibility of a brokerage for the active part of your portfolio and the unique I Bond benefit from the government platform.
The yield is the same on either platform if you buy at auction. A four-week T-bill priced at 4.34 percent on May 5, 2026 is 4.34 percent whether you buy it at Fidelity or at TreasuryDirect. Brokerages do not mark up new-issue auction prices. Where they can charge spreads is on secondary-market purchases, but on big issues like recent Treasuries the spread is usually one to two basis points and is essentially invisible at the size of an individual investor's order.
State tax treatment is the same regardless of where you buy. All Treasuries are exempt from state and local income tax. For a Tennessee resident this is irrelevant since Tennessee does not tax wages, but for someone in California, New York, or another high-tax state, that exemption matters. The exemption follows the security, not the platform. Holding a Treasury in a brokerage account in California still gives you the federal-only treatment that holding it in TreasuryDirect would.
The one operational difference worth knowing is what happens when you die. Treasuries held in TreasuryDirect require your survivors to go through TreasuryDirect's process, which is paperwork-heavy and slow. Treasuries held in a brokerage with a transfer-on-death designation move within days of the death certificate being filed. For older investors or anyone with estate planning concerns, the brokerage option is meaningfully easier on the people you leave behind. That alone is enough reason for many investors to consolidate their bond holdings inside their main brokerage and treat TreasuryDirect as a single-purpose tool for I Bonds only.
The shortest answer for someone setting up a Treasury position for the first time in 2026 is this. Open or use an existing brokerage account at Fidelity, Schwab, or Vanguard. Buy your bills, notes, and TIPS there. If you want I Bonds, open a TreasuryDirect account once and put $10,000 a year into them through that platform. Skip TreasuryDirect for everything else. The brokerage gives you better tools, faster liquidity, cleaner reporting, and an easier path for your survivors. The yield is the same. The safety is the same. The convenience is not, and convenience compounds across every decision you make over the next thirty years that you hold any part of your portfolio in U.S. government debt.
