- Treasury futures are typically Section 1256 contracts — ZB, ZN, ZF and ZT are CBOT-listed regulated futures, so they generally receive the automatic 60/40 split regardless of holding period, with no election to file.
- The maturity does not change the tax answer. The 30-year bond, the 10-year note and the 5-year note are taxed the same way; they are a duration choice, not a tax choice.
- The state tax exemption on Treasury interest generally does not follow you into the futures contract. A futures position pays no coupon and does not make you the owner of the note, so there is normally no exempt interest for that rule to reach — your gain is generally capital gain your state can tax. This is the single most misunderstood point on the topic.
- 60/40 does not automatically beat a Treasury bond ETF. Independent research has found the fund winning under a range of realistic assumptions, because the fund’s interest is generally state-tax exempt and a futures position is marked to market annually instead of deferring gain.
- These are physically deliverable contracts settled from a basket of eligible securities, unlike cash-settled index futures. Delivery is generally a taxable event, and a roll is typically a closing transaction with its own result rather than a continuation.
- A cash-versus-futures basis trade is typically a mixed straddle with its own elections and same-day identification requirements. That one is not a do-it-yourself position — every situation varies and it belongs in front of a CPA before the trade, not at filing.
Treasury futures sit in an odd place in trader tax. The contract itself is one of the most straightforward things in the tax code — a regulated futures contract, 60/40, Form 6781, done. But the underlying is the single most tax-advantaged security most investors will ever touch, and that creates a trap: traders assume some of the Treasury’s tax advantages come along for the ride. Generally they do not.
This page covers the part that is specific to the Treasury complex: the state tax question, how the contract compares to owning the actual bond or a bond fund, what physical delivery from a deliverable basket means, and why the cash-versus-futures basis trade is a professional-only position. The general §1256 mechanics live on futures trading taxes and are recapped briefly below.
Do Treasury futures qualify for Section 1256?
Generally yes. Section 1256 covers regulated futures contracts traded on a qualified board of trade, and the Treasury complex is listed on the CBOT, part of the CME Group. Being an interest rate instrument rather than an equity index or a commodity makes no difference to the treatment. The contracts most traders mean by “Treasury futures” or “bond futures”:
| Symbol | Underlying | Exchange | Settlement | Typical §1256? |
|---|---|---|---|---|
| ZT | 2-year Treasury note | CBOT | Physical | Yes |
| ZF | 5-year Treasury note | CBOT | Physical | Yes |
| ZN | 10-year Treasury note | CBOT | Physical | Yes |
| ZB | Treasury bond (the “long bond”) | CBOT | Physical | Yes |
| Interest rate swap | Rate exposure, bilateral | Not exchange-traded futures | — | No — excluded |
| Treasury bond ETF | A portfolio of actual Treasuries | Equity exchange | — | No — see below |
The CBOT Treasury complex also includes ultra contracts at the 10-year and bond maturities, and micro-sized yield futures exist as well. The tax characterisation is not what distinguishes them, so this page does not reproduce contract specifications — confirm the current contract on the exchange’s own specification page, and note that interest rate swaps, caps, floors and similar agreements are specifically outside §1256. That exclusion is aimed at swaps, not at exchange-traded Treasury futures.
There is no separate tax treatment for the 30-year versus the 10-year versus the 5-year. Moving out the curve is a duration decision, not a tax decision, and a trader running ZT, ZF, ZN and ZB together generally has one §1256 number rather than four. That is why this page covers the family rather than one page per symbol — there would be nothing different to say.
Is my Treasury futures gain exempt from state income tax?
Generally no — and this is the most consequential thing on this page. It is also the point most sources covering Treasury futures skip entirely.
Interest on obligations of the United States is exempt from state and local income tax under a federal statute, 31 U.S.C. § 3124. That is why an investor holding actual Treasury bills, notes or bonds pays federal tax on the coupon but generally no state tax on it — a real advantage in a high-tax state, and a large part of why Treasuries are held directly rather than through other wrappers.
A Treasury futures contract is a different thing. While you hold it:
- You are not the owner of the underlying note. You hold an exchange-traded contract with the clearing house on the other side, not the security itself.
- You receive no coupon. There is no interest payment flowing to you, which means there is generally no exempt interest for that rule to reach in the first place.
- Your result is capital gain or loss under the Internal Revenue Code, arrived at through the §1256 60/40 split and year-end marking — and a state that taxes capital gains generally taxes that.
The distinction holds even one step closer in: the federal exemption is written around the obligation and its interest, and the tax treatment of gain or loss on disposing of a government obligation is generally decided under the Internal Revenue Code rather than by the exemption. An investor who buys an actual Treasury note on the secondary market and sells it at a profit before maturity generally has a capital gain their state can tax, even though the coupon they collected along the way was exempt. A futures trader is further from the exemption than that investor, not closer.
The gap is largest for a trader in a high-tax state who moved into Treasury futures partly because Treasuries are “tax-advantaged.” The 60/40 split is a real federal benefit and it is worth having. But it is a federal-rate benefit, not a state-tax exemption, and the two are frequently conflated. State conformity to federal treatment also varies — some states do not follow the federal capital gains structure at all. Confirm your own state rather than generalising; a trader-specialist CPA can tell you in one conversation what this is worth where you live.
Treasury futures vs cash Treasuries vs a Treasury bond ETF
Because the same rate exposure is available three ways, this comparison comes up constantly — and the intuitive answer is often wrong. Here is the shape of it:
| Treasury futures (ZB/ZN/ZF) | Actual Treasuries held directly | Treasury bond ETF | |
|---|---|---|---|
| What you receive | Price gain or loss only | Coupon interest, plus gain or loss on sale | Distributions, plus gain or loss on sale |
| Typical federal character | §1256, 60/40, ~26.8% blended ceiling | Interest at ordinary rates; gain on sale is capital | Distributions largely interest at ordinary rates |
| State tax on the income | Generally taxable | Interest generally exempt | Treasury-source interest generally exempt |
| Timing | Marked to market annually, open or not | Interest as received; gain on sale | Distributions as received; gain on sale |
| Wash sales | Generally do not apply | Generally apply | Generally apply |
| Loss carryback | 3 years against prior §1256 gains, by election | No | No |
Read down the columns rather than across, and the trade-off is clear: the futures route wins on federal rate character and loses on state treatment and on timing. The 60/40 split is worth real money at the top bracket. But a futures position is marked to market every December 31 whether or not you closed anything, so there is no deferral, while a bond fund holder can leave an unrealised gain unrealised for as long as they like. And the fund’s Treasury-source interest generally keeps the state exemption the futures contract cannot.
Independent research has reached the counterintuitive conclusion that under a range of realistic assumptions the bond fund comes out ahead over long study periods, once the state exemption, the absence of deferral, and what the cash collateral behind a futures position earns are all counted — while noting that futures can still be compelling for a high-bracket investor with an efficient cash solution. The honest summary is that there is no universally more tax-efficient instrument here. It turns on your bracket, your state, your holding period, and how you hold the collateral.
We are not going to tell you which of the three is better for you, because the answer genuinely depends on facts a page cannot see. What we will say is that “futures get 60/40, so futures are the tax-efficient choice” is not a safe conclusion for a Treasury position, and that is how the decision is usually made. If you are choosing between these routes with meaningful size, model it properly first. This is one of the clearer cases where an hour with a CPA pays for itself.
What does physical delivery mean for my Treasury futures taxes?
Unlike the cash-settled equity index contracts, Treasury futures are physically settled: the short is obliged to deliver an actual Treasury security from a defined basket of eligible issues within the delivery window, and the contract effectively prices off whichever of those is currently the cheapest to deliver. That basket mechanic is why Treasury futures behave the way they do, and it has two tax consequences worth knowing.
First, taking or making delivery is generally a taxable event rather than a non-event. In practice a retail trader almost never gets there — brokers typically close or liquidate before the delivery window, and traders wanting continuous exposure roll into the next contract month. But the possibility is real here in a way it is not for an index trader, and a trader who does go to delivery ends up holding an actual Treasury security whose coupon is taxed under a completely different set of rules than the contract they just closed. That crossover is a CPA conversation, not a general answer.
Second, a roll is generally not a continuation. Closing the front month and opening the next is typically a closing transaction with its own gain or loss plus an opening of a new position — not one uninterrupted holding. For a §1256 contract this matters less than it would on the equity side, because the 60/40 split applies regardless of holding period and year-end marking happens anyway. But your records should reflect the transactions that actually occurred rather than treating a quarterly-rolled position as a single long trade. Exchange and clearing fees on the roll generally reduce the gain or increase the loss rather than sitting as separate deductions.
How is a cash-versus-futures basis trade taxed?
This section deliberately does not answer the question, and that is the honest response. The Treasury basis trade — long the actual security, short the corresponding futures contract, often financed in the repo market — is one of the most common institutional Treasury structures, and increasingly reached by sophisticated individual traders. Its tax treatment is materially harder than anything else on this page.
The reason is structural: one leg is a §1256 contract and the other is not. A straddle in which at least one but not all of the positions is a §1256 contract is a mixed straddle, and mixed straddles have their own regime sitting on top of everything described above. Without resolving any of it, here is the shape of what is involved:
- An election under §1256(d) can take the §1256 leg out of mark-to-market and out of 60/40, subjecting the whole straddle to the loss-deferral rules instead. It generally applies to later years and is not revocable at will.
- A straddle-by-straddle identification election operates differently again, and requires each position to be clearly identified by the close of the day the straddle is established or when a position is disposed of, whichever is earlier.
- A mixed straddle account election groups positions into classes of activity for offsetting.
- These are separate boxes on Form 6781, not variations on one choice, and the identification timing is not something you can fix at filing. Miss the day and the election is generally not available for that straddle.
Which of those elections is right — or whether a particular position is a straddle at all — turns on facts and on identification made at the time the position is opened. A page that picked an answer would be guessing with your return. If you run cash-versus-futures basis trades, this belongs in front of a CPA before the position is opened. It is the one thing on this page where the cost of getting it wrong is not a rate difference but an election you can no longer make.
The mechanics, in brief — and where the detail lives
The full explanation of §1256, the 60/40 split, year-end mark-to-market, Form 6781 and the three-year loss carryback belongs on one page rather than being repeated per contract, and it is on futures trading taxes. The short version, so this page stands on its own:
- 60/40 is automatic. Gains and losses on a qualifying contract are treated as 60% long-term / 40% short-term regardless of holding period, with no election to file. For most traders that puts the top blended federal rate near 26.8% rather than up to 37%.
- Open positions are marked to market at year-end. A position still open on December 31 is generally treated as sold at that day’s closing price, and the resulting gain or loss counts for that year even though nothing was closed.
- Reporting runs through Form 6781, not Schedule D directly, and the broker’s 1099-B generally reports a §1256 aggregate figure rather than trade-by-trade detail. Filing only on Schedule D and skipping Form 6781 is a common source of IRS notices.
- Wash sales generally do not apply to §1256 contracts — a loss taken and the position immediately reopened is typically still deductible, unlike on the cash bond or bond fund side.
- Losses can typically be carried back three years against prior §1256 gains by election, which is unusual and worth knowing after a bad year in rates.
- Commissions and exchange fees generally reduce the gain or increase the loss rather than being separate deductions; platform, data and subscription costs are a different category — see trader tax deductions.
Two adjacent decisions interact with all of this: whether you qualify for trader tax status, and whether a §475 mark-to-market election makes sense — noting that electing MTM on commodities can convert §1256 gains into ordinary income, which usually works against a futures trader and would specifically give up the 60/40 benefit described above. Because nothing is withheld from trading gains, quarterly estimated payments are generally how traders avoid an underpayment penalty. The Section 1256 calculator estimates what the 60/40 split is worth against ordinary short-term rates.
Does a Treasury futures payout from a prop firm get the same 60/40 treatment?
Typically no, and this is the most expensive misunderstanding in this whole cluster. Section 1256’s 60/40 split attaches to a qualifying contract held in your own account. When you trade ZB or ZN inside a funded account belonging to a prop firm, the contract is not yours — the firm’s is. What you receive is a share of profits paid for your trading services.
For most US traders that payout is therefore ordinary income, commonly self-employment income on Schedule C, carrying income tax at your marginal rate plus 15.3% self-employment tax on 92.35% of net earnings — not the roughly 26.8% blended ceiling that applies to Treasury futures positions held in your own account. The instrument being traded does not change that; the ownership of the account does. Note that the prop payout is also generally state-taxable, so on that axis nothing is gained either.
A trader who reports prop payouts as 60/40 gains may be understating tax on a position that is difficult to support. A trader who reports their own Treasury futures profits as ordinary income may be overpaying. A trader who does both in the same year has two different kinds of income and typically tracks them separately — same screen, same ticker, different tax character.

Frequently Asked Questions
Are Treasury futures Section 1256 contracts?
Generally yes. ZB, ZN, ZF and ZT are regulated futures contracts listed on the CBOT, part of the CME Group complex, so they typically fall under Section 1256 and receive the automatic 60% long-term / 40% short-term split regardless of holding period. Being an interest rate instrument rather than an equity index makes no difference to the treatment. Reporting runs through Form 6781, and open positions are generally marked to market at year-end. Note that interest rate swaps and similar agreements are specifically excluded from Section 1256 — the exclusion is for swaps, not for exchange-traded Treasury futures.
Is my Treasury futures gain exempt from state income tax?
Generally no, and this is the most common misunderstanding on this topic. The federal exemption at 31 U.S.C. § 3124 covers interest on obligations of the United States — the coupon on an actual Treasury note or bond. A futures contract pays you no coupon and does not make you the owner of the underlying note while you hold it, so there is generally no exempt interest for that rule to reach. Your Section 1256 result is capital gain or loss under the Internal Revenue Code, and states that tax capital gains generally tax it. State conformity varies, so confirm your own state with a CPA.
Are Treasury futures more tax-efficient than a Treasury bond ETF?
Not automatically, despite the 60/40 headline. Independent research has found the bond fund winning under a range of realistic assumptions, because the fund's Treasury interest is generally exempt from state and local income tax while a futures gain generally is not, and because Section 1256 positions are marked to market every year rather than deferring gain until sale. Which route is better depends on your bracket, your state, your holding period and what the cash collateral earns. Every situation varies and this is worth modelling with a CPA rather than assuming 60/40 settles it.
Do I need a separate page or form for ZN versus ZB?
Generally no. ZN, ZB, ZF and ZT are different maturities of the same kind of instrument and typically receive the same Section 1256 treatment, so the tax answer does not change by contract. They are normally reported together as part of the Section 1256 aggregate on Form 6781 rather than separately. Your broker's 1099-B generally reports one combined Section 1256 figure rather than trade-by-trade detail.
What happens if I take delivery of a Treasury futures contract?
Treasury futures are physically settled from a basket of eligible securities rather than cash-settled, so delivery is a real possibility in a way it is not for index futures. Taking or making delivery is generally a taxable event, and it also leaves you holding an actual Treasury security whose coupon income is taxed on entirely different rules from the contract you just closed. Retail traders normally close or roll well before the delivery window. A trader who does go to delivery has a materially different set of facts and that is a conversation with a CPA rather than something a general page can resolve.
How is a cash Treasury versus Treasury futures basis trade taxed?
This is genuinely complicated and we will not give you a general answer. A long cash Treasury against a short futures contract is typically a straddle in which one leg is a Section 1256 contract and the other is not — a mixed straddle. That triggers its own regime, including an election under Section 1256(d) to take the Section 1256 leg out of mark-to-market, the identified mixed straddle rules, and the mixed straddle account election, each identified in a different part of Form 6781 and several requiring identification on the day the position is established. Getting the identification timing wrong is not fixable later. If you run basis trades, this belongs in front of a CPA before the position is opened, not at filing time.
