Bitcoin Ordinals Tax Switzerland Inscriptions 2026

I hold inscriptions. When I went to declare them for Swiss wealth tax in early 2025, I found a blank. No ESTV Kursliste entry. No published cantonal guidance. No FINMA ruling that addressed inscriptions as a distinct asset class. The gap has not closed as of 2026-06.

This post documents what the law says, where the framework is unsettled, and how you build a defensible declaration file while that gap stays open.

TL;DR

Bitcoin inscriptions are taxable assets under Swiss wealth tax (StHG Art. 13). ESTV has not published an inscription-specific reference price as of 2026-06. You self-assess fair-market value using documented marketplace snapshots on December 31. A private investor's sale should follow the zero-CGT framework under DBG Art. 16 Abs. 3, though no ESTV ruling confirms this for inscriptions by name. The professional-trader test applies. Cross-border transfers via regulated intermediaries fall within AMLO-FINMA Art. 51. This is education. Consult a licensed Swiss Steuerberater before declaring any inscription portfolio.

Ordinals as Vermögensbestandteil

Swiss wealth tax hits every taxable asset under StHG Art. 13. The statute casts a wide net. Vermögen covers anything with a realisable monetary value. An inscription is a satoshi carrying arbitrary data, transferred to your custody. It has a market price. It is transferable. You can sell it. That makes it a Vermögensbestandteil.

No ESTV ruling explicitly classifies inscriptions as movable private assets or as intangible property. The closest analogy in Swiss practice is unlisted securities and other financial assets valued at fair market value per the ESTV Wegleitung, which cantonal authorities apply to assets without an official reference price. The SBF Tax Framework Review Switzerland 2026/02 (Version 1.3e, March 2026, blockchainfederation.ch) covers digital assets broadly but says nothing about inscription-specific valuation. The guidance gap is explicit and outstanding.

The working position, consistent with general Swiss tax principles: inscriptions belong in your Wertschriften und Guthaben declaration at December 31 fair market value. That position is reasonable. No ESTV ruling confirms it.

The inscription mint date as acquisition date

The mint date is your economically logical acquisition date. The inscription gets created at a specific block height, tied to a specific on-chain transaction, and lands in your wallet at that moment. Swiss tax practice for movable assets uses the transfer date as the acquisition date.

ZH Steuerverwaltung has not published inscription-specific guidance on this point as of 2026-06. The ZStB sections covering digital asset valuation (zh.ch/de/steuern-finanzen) handle Bitcoin and listed digital assets but skip sub-asset classes within the ordinals ecosystem. Unsettled.

Use the block timestamp of your mint transaction as the acquisition date. Document it with:

• The ordinal inscription ID (the unique sequential number from ordinals.com or ordiscan.com)
• The on-chain transaction ID of the inscription
• The block height and timestamp

This documentation supports your cost basis record and any future ESTV review of acquisition timing. For the technical mechanics of how inscriptions get created and tracked, see the Bitcoin Ordinals explained guide.

Fair-market self-assessment without an ESTV Kursliste entry

The ESTV Kursliste (estv.admin.ch / ICTax) publishes December 31 reference prices for major digital assets. Bitcoin, Ether, and many listed tokens appear. Individual inscriptions do not. No inscription-specific valuation guidance lives in the Kursliste as of 2026-06. You apply a fair-market self-assessment and document it.

Swiss tax practice for unlisted assets calls for a documented fair-market approach. For inscriptions:

Step 1: Take marketplace snapshots on December 31. Visit Magic Eden Ordinals (magiceden.io/ordinals), Gamma.io, and the OKX Ordinals marketplace. For each platform, record the listed prices for your inscription or for comparable inscriptions from the same collection, with a timestamp showing December 31. Do this at multiple points during the day (morning, midday, close of European trading) to capture the price range.

Step 2: Record the ordinal inscription ID. Each inscription carries a permanent unique identifier in the format <inscription-number>i0. Note it in your documentation alongside the marketplace snapshots.

Step 3: Convert to CHF. Convert the USD or BTC listed price to CHF using the Swiss National Bank reference rate for December 31 (snb.ch/en/the-snb/mandates-goals/statistics/statistics-pub/zinsen-renditen).

Step 4: Apply a consistent methodology. Use the midpoint of the observed price range as your declared CHF value. Document your methodology in writing so that if your cantonal authority asks, you can explain how you arrived at the figure.

Step 5: Keep the file. Store the screenshots, CHF conversion, and methodology note with your tax documents for the applicable year. Swiss cantonal authorities can request supporting documentation up to 10 years after the assessment under DBG Art. 152.

No ESTV guidance covers this process as applied to inscriptions. The methodology follows general Swiss unlisted-asset practice. A licensed Steuerberater can validate or improve it for your situation.

The professional-trader test applied to ordinal trading

The zero-CGT exemption under DBG Art. 16 Abs. 3 covers only private investors. If ESTV or your cantonal authority reclassifies you as a professional trader (gewerbsmässiger Händler), your ordinal sale gains become taxable as ordinary income. ESTV applies the same five-indicator test from Kreisschreiben Nr. 36 to all digital asset activity, inscriptions included, by analogy. See the full framework in Bitcoin Tax Switzerland.

The five criteria that keep you on the private-investor side:

1. Holding period at least six months. Buying and flipping inscriptions within weeks signals trading intent. A single short turnaround rarely decides anything. A pattern will.

2. Annual transaction volume not exceeding five times your start-of-year portfolio. KS Nr. 36 measures your total transaction volume as a ratio to your Wertschriften- und Guthabenbestand at the start of the tax period. High-frequency inscription trading against a small starting portfolio fails this ratio fast.

3. No leverage or borrowed capital. Funding inscription purchases with a Bitcoin-backed loan is the single most damning indicator. Avoid it.

4. Trading income not necessary to cover living expenses. If inscription sale profits exceed 50% of your total net income from other sources in a tax year, the private-investor safe harbour fails.

5. Derivatives used only to hedge, not as speculative instruments. Systematic use of options or other derivatives beyond hedging an existing position classifies as professional activity.

Ordinals trading carries more risk than Bitcoin holding. Inscription markets are less liquid and more volatile. If you rotate frequently between collections and take short-term positions, assess your activity pattern against all five criteria before you assume the private-investor exemption applies.

AMLO-FINMA cross-border ordinal transfers

AMLO Art. 51 requires FINMA-supervised Swiss financial intermediaries to apply anti-money-laundering due diligence to transactions involving digital assets with economic value. This catches cross-border transfers routed through Swiss-regulated exchanges or brokers. It does not catch private peer-to-peer wallet transfers.

If you receive an inscription purchased on a foreign marketplace via a FINMA-supervised Swiss custodian, that intermediary owes AMLO obligations including identity verification and transaction monitoring above FINMA's thresholds. For high-value inscriptions transferred through such a channel, expect the intermediary to apply enhanced due diligence per AMLO Art. 6.

If you sign a transaction offline using Coldcard with Sparrow Wallet via PSBT (Partially Signed Bitcoin Transaction) to move an inscription between your own wallets, you are not an AMLO-regulated intermediary and the intermediary obligations do not bind you directly. You still need to document the transfer for your tax file, particularly if the inscription's CHF value shifts materially between your acquisition and transfer dates.

DBG Art. 16 Abs. 3 capital-gains exemption and ordinal sales

DBG Art. 16 Abs. 3 exempts from federal income tax the capital gains from the alienation of movable private assets. The parallel cantonal provision is StHG Art. 7 Abs. 4 lit. b. Together they cover federal direct tax and cantonal/municipal income tax.

An inscription is movable. You hold it as a private asset if you qualify as a private investor under the five-indicator test above. ESTV has not issued a ruling extending or limiting this exemption to ordinal inscriptions as a distinct asset class. The Swiss Blockchain Federation 2026 Tax Framework Review treats digital assets broadly as movable private assets but skips inscription sub-classes.

The working position: a private investor's gain from selling an inscription should fall within DBG Art. 16 Abs. 3. No ESTV circular, Federal Tax Appeals Court ruling, or cantonal Steuerkommission decision confirms it as of 2026-06. It is the general framework applied by analogy to an asset class that did not exist when the framework was drafted.

If you sell inscriptions at material CHF gains, the unsettled status is reason enough to consult a licensed Steuerberater before you file.

Worked example mint hold sell

A concrete fact pattern. It is illustrative, not a calculation for your return.

Facts. Mohamed mints one Bitcoin inscription in January 2024 at a total cost of 0.003 BTC (inscription fee plus on-chain transaction fees), roughly CHF 180 at the January 2024 spot rate. He holds the inscription in self-custody through December 31, 2025, and sells it on a marketplace in March 2026 for CHF 25,000 net of marketplace fees.

Wealth tax 2024 (first full year of holding). Mohamed takes three price snapshots of comparable inscriptions from the same collection on December 31, 2024 on Magic Eden, Gamma, and OKX. The midpoint of observed prices indicates a fair market value of CHF 4,500. He declares CHF 4,500 in his 2024 Wertschriften und Guthaben. His canton's effective wealth-tax rate on net wealth above the Freibetrag is roughly 0.5%. The wealth-tax cost attributable to this holding is around CHF 22.50 for 2024.

Wealth tax 2025. Same methodology on December 31, 2025. Fair market value based on marketplace snapshots: CHF 18,000. Same 0.5% rate: roughly CHF 90.

Capital gain on sale in 2026. Gross CHF proceeds: CHF 25,000. Acquisition cost: CHF 180. Gain: CHF 24,820. Mohamed is a private investor. He has held the inscription for over two years, well beyond six months. His total annual trading volume is minimal against his portfolio. He uses no leverage. His employment income substantially exceeds his inscription gains. He uses no derivatives.

Applying DBG Art. 16 Abs. 3 by analogy: the gain is tax-free at federal and cantonal level. CHF 24,820 is Mohamed's to keep.

No ESTV circular confirms this result for inscriptions specifically. Mohamed documents his holding period, his five-indicator assessment, and the marketplace sale receipts. He consults a Steuerberater before filing his 2026 return, given the unsettled inscription-specific framework.

Satoshi rarity premiums and the valuation problem

Inscriptions on rare satoshis command premiums beyond the inscription content itself. An inscription on a satoshi from the first 1,000 blocks, or on an "uncommon" first-sat-of-a-block, or on an "epic" first-sat-of-a-halving-epoch, can trade at a multiple of comparable inscriptions on common satoshis. The rarity tier system is defined at docs.ordinals.com and explored in Bitcoin satoshi rarity.

Swiss tax law has no mechanism that recognises rarity premiums as a distinct valuation category. You cannot declare an inscription at a discount because its rarity premium is speculative. You declare it at December 31 fair market value, which for a rare-sat inscription means the prices at which comparable assets actually traded on that date, rarity premium and all.

This creates a documentation problem for high-rarity inscriptions with thin secondary markets. If no comparable sale occurred near December 31, you have limited data to anchor your valuation. Conservative practice: use the last available arm's-length transaction price plus your own assessment of market movement since that date, documented in writing. This is genuinely unsettled territory.

What to do right now

Three steps for Swiss inscription holders in 2026.

First, locate every inscription in your custody. Pull the ordinal inscription ID for each from ordinals.com or ordiscan.com. If you lost track of which UTXOs carry inscriptions, an Ordinals-aware wallet such as Xverse or UniSat will scan your addresses and surface them.

Second, build a December 31 documentation file. For each inscription held at year-end: ordinal ID, mint transaction, block height, three marketplace price snapshots with timestamps and CHF equivalents. Do this for every December 31 you have held inscriptions. The 10-year Nachsteuer look-back under DBG Art. 152 means past years matter.

Third, consult a licensed Swiss Steuerberater before filing if your inscription portfolio has material CHF value. The framework I described is the most defensible reading of current law by analogy. It is not confirmed guidance. The gap between what the law says about digital assets and what it says about inscriptions specifically is real and open as of 2026-06.

This is education, not tax advice. Ordinals are an unsettled area for Swiss tax authorities. ESTV has not published an inscription-specific valuation guideline as of 2026-06. The legal positions described here apply general Swiss tax principles by analogy to an asset class that lacks specific ESTV or Federal Court treatment. Individual circumstances vary across cantons, holding periods, and transaction volumes. Consult a licensed Swiss Steuerberater before declaring any inscription portfolio.
