The yield from a tokenized Treasury is generally taxed in the US as ordinary income at the federal level, like the interest on any Treasury security - but there is a valuable wrinkle: interest on US Treasuries is normally exempt from state and local income tax. Whether you capture that state exemption, and whether your return is even characterized as "interest" at all, depends on how the specific product is structured. A token holding Treasuries directly behaves differently from one that is a share of a fund, and an accruing-value design differs from a distributing one. These distinctions are why this is an advanced topic worth getting right.

The federal baseline

Interest earned on US Treasuries is taxable federally as ordinary income. So a tokenized Treasury's yield is, at the federal level, taxed at your ordinary income rate - not the lower long-term capital-gains rate. That is the starting point for any structure.

The amount is taxed in the year you earn it, whether or not it ever hits your bank account. Even if your product accrues value rather than paying you cash, the economics are interest, and the tax usually follows the income as it accrues or is distributed.

The state-tax exemption

Here is the benefit worth knowing: interest on direct US Treasury obligations is generally exempt from state and local income tax. For investors in high-tax states, that exemption is a real part of the after-tax return.

Whether your tokenized product passes that exemption through depends on structure. A token representing direct Treasury holdings is more likely to preserve it. A token that is a share of a fund may pass through the state-exempt portion only to the extent the fund's income came from direct Treasuries - many government money funds report this percentage annually. Watch one trap here: a few states (California, New York, and Connecticut among them) only let you claim the exemption if the fund held at least 50% US government obligations across the year, so a fund that dipped below that line passes through nothing in those states even if most of its income was Treasury interest. Check whether, and how much of, the state exemption applies to your specific product.

How the wrapper changes things

Two structural choices matter most. First, direct holding vs fund: a fund wrapper means your income may be reported as fund dividends, with the Treasury-interest character (and state exemption) passed through only in part. Second, distributing vs accruing: a distributing token pays you income that is taxed as received, while an accruing token - where yield shows up as a rising net asset value or token price - may raise the question of whether some return is interest income as it accrues or a capital gain realized on sale. The answer depends on the product's legal design and tax reporting.

Because these designs are new and the tax characterization can be genuinely uncertain, this is a case where reading the issuer's tax documentation and consulting a tax professional is not optional for larger positions.

What to do

Find out, for your specific product: how income is reported (interest, dividend, or gain), what portion qualifies for the state-tax exemption, and whether yield is taxed as it accrues or only on sale. Keep the issuer's annual tax statements, since they often contain the state-exempt percentage you need. Then report accordingly - the next guide, reporting RWA crypto to the IRS, covers the forms.
