Tax guide for digital asset disposals

This guide describes general tax mechanisms. It is not advice, it takes no account of your situation, and it replaces neither a professional nor the texts in force in your country. Rules change, often every year.

What it does give you: the structure shared by most regimes, the data to keep, and the method mistakes that cost the most.

Three questions that decide everything

Whatever the country, a tax regime for digital assets answers three questions. Spotting them lets you read any national documentation without getting lost.

1. What triggers tax? Some regimes only tax the exit into legal tender; others also tax swaps between digital assets. That single difference changes the record-keeping burden entirely: in the first case you track money in and money out, in the second every trade.

2. How is the gain computed? Three methods dominate: weighted average cost, first in first out, or a formula based on total portfolio value. They give different results on the same operations.

3. At what rate, and under which status? Flat rate or progressive scale, occasional or professional status. The second is almost never defined by a numeric threshold, which makes it unpredictable without professional advice.

The common ground: disposal for money

Almost every regime agrees on one point: converting a digital asset into legal tender is a tax event.

That is exactly the operation you perform on a service like ours. The conversion is therefore not a technical detail in your history: it is generally the line that counts.

Practical consequence: a conversion receipt is worth more than any wallet screenshot. It carries a date, a quantity, an amount received and a fee breakdown.

What to keep, operation by operation

Six pieces of data are enough to reconstruct an operation before any administration.

| Data point | Why it matters | | --- | --- | | Date and time | Sets the tax year and the day's exchange rate | | Asset and quantity disposed of | Basis of the gain calculation | | Network and transaction hash | Independently verifiable proof | | Net amount received, with currency | The disposal price in most regimes | | Fees borne, line by line | Deductible in many regimes | | Destination account | Establishes that the funds came back to you |

Your account holds those six items for every order and exports them in a format an accountant or filing software can use. The exact path is in the help centre.

What we cannot compute

The limit matters, because some services cross it and produce wrong numbers.

We see what you sell with us. We do not see:

• Your acquisition price. You bought elsewhere, or received, or mined.
• Your other holdings. Regimes reasoning on total portfolio value require data we do not have.
• Your operations at other providers. They count towards thresholds and towards the calculation.
• Your personal situation. Tax residence, status, other income.

A service that displays "your tax" from the operations it alone sees is giving you an estimate whose inputs it does not know. We supply the data, not the result.

The costliest method mistakes

Confusing gross and net. The disposal price is what you receive, not the mid-market value before fees. Using gross artificially inflates the declared gain. The distinction is developed in Headline rate versus effective rate.

Ignoring small operations. Exemption thresholds often apply to the annual total of disposals, not to each operation in isolation. A series of small sales can cross the threshold.

Overlooking holding-reporting duties. In several countries, declaring an account opened abroad is an obligation separate from tax on the gain, penalised separately, and due even when the account is empty or unused.

Reconstructing history after the fact. Platforms shut down, interfaces change, exports disappear. Export your operations when you make them, not the following year.

Assuming a crypto-to-crypto swap is never taxable. True in some regimes, false in others. That assumption produces the largest discrepancies.

A minimal record-keeping system

You do not need specialised software to keep correct records. You need to be regular. Here is a system that works with a plain spreadsheet and survives a platform shutting down.

An "in" sheet. Every time you convert legal tender into digital assets: date, amount in money, asset received, quantity, fees, platform. This is what builds your acquisition price, the data nobody but you holds in full.

An "out" sheet. Every disposal for money: date, asset, quantity, net received, currency, fees, network, transaction hash, destination account. Those lines come straight from your receipts.

A "valuations" sheet. One line per disposal date with the total value of your holdings on that day, if your national regime needs it. It is the tedious part, and it is also the part that is impossible to reconstruct a year later.

A backup rule. Export each platform's operations at least quarterly, and keep the files off the platform. An export made on the day you need it is an export you may no longer have.

The system computes nothing. It simply guarantees that on the day you, or your accountant, have to compute, every input will be available. That is the one part of the work software cannot do for you, because it depends on data scattered across several providers, some of which will no longer exist.

The move to automatic transparency

The international framework for exchanging information is being extended to digital assets. Providers will be required to report their customers' operations to their administration, with onward transmission between national administrations.

The practical effect is easy to anticipate: divergence between what you declare and what the administration receives will become mechanically visible, with no investigation needed. Keeping records as you go stops being a precaution and becomes the only reasonable option.

The country pages

Every country page on this site shows a high-level tax note where we have one, purely for information. It states the general principle that applies, never a calculation. See the list on countries served.

The French case is treated in detail in French crypto disposal tax: taxable event, calculation formula, exemption threshold, forms, foreign accounts.

Two questions we are asked and will not answer

"Is this operation taxable for me?" The answer depends on your tax residence, your status, the origin of the assets and your other income. Any answer given without those inputs is a guess dressed up as information, and on a financial subject that is worse than no answer at all.

"Which method should I choose when several are available?" Where a regime offers an option — a flat rate or a progressive scale, one valuation method or another — the right choice is a calculation over your whole tax position, not over your crypto operations. A service that recommends one is telling you something it cannot know.

What we will always answer, precisely: what data our export contains, how a receipt figure was produced, which fee lines were applied and on what basis, and where in your account the document you need lives. That is the boundary between information and advice, and we keep it visible rather than blurring it to seem more helpful.

When to consult a professional

Without hesitation, in four situations:

1. Your activity is intense. The line between occasional and professional has no numeric threshold, and the professional regime changes everything.
2. You have changed tax residence. The rules attaching a gain to a country are complex and rarely intuitive.
3. Your assets came from something other than a purchase. Mining, staking, airdrops, being paid in digital assets: each has its own treatment.
4. The amounts are significant. The cost of advice is negligible against the cost of a reassessment.
