Crypto Options Tax Explained: Deribit, IBIT Calls and CME in 7 Countries

Three bitcoin options can sit on three completely different tax machines — even though all three expire on a Friday and reference the same coin. Only one of them gets the famous US 60/40 split. Here's how premium, exercise, assignment and expiry actually work, venue by venue, in seven countries.

Image: Illustrative purposes. Tax rules cited from IRC §§49 context, 1092, 1234, 1256 and 1259, IRS Notice 2014-21, HMRC Cryptoassets Manual and BIM spread-betting guidance, §20 EStG, ITA s.49, ITAA 1997 Div 134, NTA derivatives guidance, and Indian Income Tax Act §115BBH.

The first bitcoin option I ever bought cost me 0.02 BTC on Deribit. It expired worthless nine days later. My instinct was to treat the premium like a losing bet — gone, over, nothing to declare. Honestly, that instinct was wrong twice over. Paying the premium in BTC was itself a taxable disposal of bitcoin, and the expired option was a separate capital loss I needed to report on Form 8949.

Here's the thing: the word "option" covers three instruments with almost nothing in common for tax. There are offshore crypto-settled options on Deribit, Binance and OKX, where premium and settlement happen in BTC and no US information return exists. There are listed options on spot bitcoin ETF shares like IBIT — except it's unsettled whether those grantor-trust shares are even "stock." And there are CME bitcoin futures options, squarely inside IRC §1256 with its 60/40 split and year-end mark-to-market.

Same underlying. Same Friday expiry. Three answers. This piece is purely about options — premium, expiry, exercise and assignment, and why venue beats strategy. Funding fees, funding payments and liquidations live in the companion futures and perpetuals guide.

1. The four endings of an option (US baseline)

First, the mechanics. Under §1234, an option is a capital asset in the holder's hands and the premium is its basis — not a fee or wager you deduct on the way in. The tax result depends on how the contract ends. Four endings:

• It expires worthless. The buyer is treated as selling the option for zero on expiry day: the premium becomes a capital loss, normally short-term since few options run over a year (long-dated LEAPS can be long-term). The writer recognizes a short-term capital gain equal to the premium.
• You close it early. Selling a long option, or buying in a short one, is a sale. Gain or loss follows the contract's own holding period — short-term for nearly everything retail traders touch.
• A call you bought is exercised. No separate gain on the option: the premium folds into the asset you acquire — basis = strike plus premium. For the assigned call writer, it increases amount realized on the delivered coin or shares.
• A put you bought is exercised. The premium reduces your amount realized on the coin sold at the strike; for the assigned put writer it reduces the basis of property put to them.

One asymmetry to internalize: everything a writer earns is short-term. The short-sale mechanics of §1233(b) and the option rules deny writers long-term character no matter how long the position stayed open. Only buyers holding a LEAPS-style contract over a year can get long-term treatment — rare in crypto.

2. The venue decides everything: §1256 and the three buckets

If mechanics are the engine, venue is the transmission. §1256 grants the 60/40 split regardless of holding period, year-end mark-to-market, and a special rule letting net §1256 losses be carried back three years. But it covers only a nonequity option or future traded on a qualified board or exchange — a CFTC-designated contract market, an SEC-registered securities exchange, or a Treasury-designated foreign board.

Map that onto the three crypto buckets:

Bucket 1 — CME bitcoin and ether futures options: clearly §1256. Options on CME BTC/ETH futures are nonequity options on a CFTC-designated contract market. Report on Form 6781, take the 60/40 blended rate (~27.8% at the top bracket before NIIT), mark open contracts to fair value each 31 December, and keep the carryback. It's the same machine as CME futures in the futures and perps guide — the reason tax-aware traders often use the CME curve despite wider spreads.

Bucket 2 — Deribit, Binance, OKX and on-chain venues: ordinary property. None is a qualified board — Deribit blocks US customers because it isn't registered, and Lyra, Premia, Aevo and Ribbon-style vaults aren't designated markets. Trades fall under Notice 2014-21 as property on Form 8949: short-term rates up to 37% under a year, no mark-to-market, no carryback. These venues send no 1099-B to US persons — a reporting gap, not an exemption.

Bucket 3 — listed options on IBIT and the other spot bitcoin ETFs: genuinely gray. An equity option is an option on stock, but IBIT is a grantor trust — shares are beneficial interests in a bitcoin-holding trust, the structural point from the bitcoin ETF versus direct BTC guide. If trust shares aren't "stock," a listed option on them is arguably a nonequity option on a registered exchange: §1256, 60/40, mark-to-market. Some practitioners take that position. The problem is broker practice — most 1099-Bs I have seen report IBIT options as plain equity options with no split, and the IRS has given no answer. For meaningful size, document your position, reconcile it to the 1099, and use a professional.

3. Paying in BTC is a trade inside the trade

Offshore venues add a layer a dollar brokerage account doesn't have. Deribit premiums are quoted and settled in crypto, so spending 0.05 BTC on a call is itself a disposal of bitcoin at fair market value: you realize gain or loss on that BTC lot under Notice 2014-21 and separately take an option basis equal to the same FMV. Two events, one click.

The writer has the mirror: 0.05 BTC received is proceeds at receipt-date FMV, and that coin carries its own built-in gain for later. Physical exercise or delivery — Deribit settles into its underlying future, some venues deliver coin — is another disposal at exercise-date FMV.

The weekend trap: crypto never closes, so "FMV at 23:47 UTC Saturday" is a number you must pin down. Use one consistent pricing source and timestamp every premium in dollars — audit disputes here are almost always FMV disputes.

4. Protective puts, covered calls and the two loss regimes

Hedge coin you actually hold and two old securities regimes wake up. The §1092 straddle rules defer a loss on one leg while an offsetting position stays open, and §263(g) can capitalize carrying charges instead of deducting them. A protective put on owned bitcoin, or calls written against vaulted coin, creates exactly this: realize the losing leg first and the IRS may suspend it until the other side closes.

There's a holding-period sting: a protective put that isn't a same-day, identified "married put" can toll or extinguish the long-term clock under the qualified-covered-call rules and §1259. Hedged short-term coin may never start its 12-month clock; long-term coin can be pulled back to short-term under a deep-in-the-money call overhang. In crypto, where the whole rate game is the 12-month line, that hurts.

Then the odd wash-sale split. Direct crypto is still outside the wash sale rules — why crypto tax-loss harvesting works — but IBIT shares and their options are securities, firmly inside the wash sale rule: harvest an IBIT call loss and buy a substantially identical position within 30 days and the loss vanishes into basis. One hedged portfolio can run both regimes at once. Keep the sleeves separate.

5. The seven-country map

Outside the US, countries divide on three questions: capital asset or bet, does the venue's licence change the rate, and how badly are losses treated? The notes after the table cover what trips people up most.

United Kingdom. HMRC treats traded options as CGT assets: an expired long is a capital loss, writer premium is capital proceeds, and exercise folds the premium into cost or proceeds as in the US. Annual exempt amount £3,000, rates 10%/20%. The exception is spread betting: exposure structured as a spread bet through a UK firm is tax-free for a normal individual, but losses give no relief — and HMRC can reclassify organised, frequent, geared activity as a trade, flipping gains to income tax. Offshore crypto-settled platforms don't inherit that exemption; most investors report them as CGT, and CARF-era exchange data is coming regardless.

Germany. Surprise: options are not under the §23 one-year rule that makes year-held bitcoin tax-free. They sit in §20 Abs. 1 Nr. 11 EStG as capital income from Termingeschäfte, including Stillhalterprämien (writer premiums), at the flat Abgeltungsteuer: 25% plus solidarity surcharge ≈ 26.375%, roughly 27.5–28% with church tax. No holding-period escape. Losses are ring-fenced under §20 Abs. 6 against same-category capital income, and since 2021 term-transaction losses have been capped at €20,000 per year; promised repeals have not fully cleared the legislature, so assume it applies until your advisor says otherwise. Run it as a business and it becomes Gewerbe income with trade tax.

Canada. ITA s.49 governs. An expired long gives the holder a capital loss equal to premium; the writer realizes a premium-sized capital gain. On exercise the premium rolls into ACB (call) or adjusts proceeds (put). Employee stock-option deductions are irrelevant — crypto options don't qualify. Investors get the 50% inclusion; the CRA's trading badges can flip systematic writing to 100%-taxable business income (see the trader-status guide).

Australia. The ATO splits an option into CGT events: the writer's premium is a capital-proceeds event at grant (the statute's grant event is D2; some import tools label the premium line "E3" — same concept). Expiry or abandonment crystallises the holder's loss. Exercise is not a separate event: ITAA 1997 Division 134 collapses grant plus exercise into the underlying transaction, premium rolling into cost or proceeds. The 50% discount can apply after 12 months on the resulting coin. And don't import the UK spread-betting exemption — Australian residents get no such free pass.

Japan. The venue-dependence extreme. Market derivatives under the Financial Instruments and Exchange Act — including CME bitcoin options via a Japanese licensed broker — use separate taxation at a flat 20.315% (15% income, 5% resident, 0.315% reconstruction), with three-year loss carryforward and possible aggregation with listed equity results. Unlicensed overseas platforms, peer-to-peer contracts and on-chain products instead land in 雑所得 (miscellaneous income) at progressive rates to roughly 55%, with no meaningful carryforward. Promised reform keeps slipping — don't file on a future flat rate.

India. Crypto-settled options sit in the §115BBH box: flat 30% plus 4% cess, no deduction beyond cost, no loss set-off, no carryforward, plus 1% TDS on consideration (creditable on your return). There is no §1256, no 60/40, no mark-to-market; old speculation-business distinctions are overtaken by the VDA framework. Premium paid in crypto triggers the standard VDA disposal on the coin — the same second layer as in the US.

6. A full example: Elena's expired Deribit call

Elena bought bitcoin across 2024–25. On 1 March she buys an out-of-the-money Deribit BTC call, strike $65,000, June expiry, premium 0.05 BTC with BTC at $60,000 — a $3,000 premium.

• Layer 1 — spending the coin. The 0.05 BTC comes from a lot acquired at $42,000: spending it is a disposal of 0.05 × ($60,000 − $42,000) = a $900 capital gain, long- or short-term depending on the lot's age, on Form 8949.
• Option basis. Her basis in the call is the premium's fair market value: $3,000.
• Expiry. BTC settles at $61,200 in June and the call expires: a deemed sale at zero, a $3,000 short-term capital loss on Form 8949. Not 6781 — Deribit isn't §1256 — so no 60/40, no mark-to-market, no carryback.
• Net effect. A $900 gain and a $3,000 loss: net −$2,100, but the lines are separate; without other gains only $3,000 of net capital loss offsets ordinary income, the rest carrying forward. In Germany both legs run through the §20 pot at 26.375%; on an unlicensed platform in Japan, progressive miscellaneous income.

The writer on the other side has the mirror: 0.05 BTC received is a $3,000 short-term capital gain at expiry, plus a fresh 0.05 BTC holding with a $3,000 basis awaiting its own future disposal.

7. Keeping the books sane

After a few dozen contracts, journaling breaks. Three habits. One: venue-segregated books — CME (6781, 60/40, mark-to-market), IBIT-style securities (1099-B, wash-sale exposure), offshore crypto options (8949 plus second-layer coin disposals). Pool them and the forms and rates won't reconcile. Two: log the dollar FMV of every premium on its timestamp — it's simultaneously your option basis, your disposal proceeds on the coin, and the writer's income value.

Three: expect a reporting gap, not a holiday. Your broker reports IBIT and possibly CME; Deribit, Binance and OKX send nothing, and the 1099 matching program doesn't care that the missing venue was offshore. This is where CSV consolidation pays: export every venue and chain, merge them in the free batch importer for one FIFO-matched schedule, then check your number on the US tax page or your country page — especially for the IBIT gray zone, where your position should match or deliberately explain the broker's 1099.

Bottom line

With options, venue does more work than strategy. A CME futures option is §1256: 60/40, mark-to-market, three-year carryback. The same payoff on Deribit is short-term property with a second event baked into the BTC premium; an IBIT call is a gray zone your broker may report either way. Mechanics stay constant — premium as basis, expiry as sale, exercise as basis adjustment, writers always short-term — but the rate, form and loss rules come from where the contract trades. Separate the books, pin the FMVs, and never mistake an unreported venue for a tax-free one.

Educational information only, not tax advice. The equity-option status of grantor-trust ETF shares and the offshore-venue treatment in several jurisdictions are unsettled as of September 2026, and reform in Japan and the US could move positions. For material size, confirm your filing position with a licensed professional in your country.
