Definition

Tokens received without consideration, raising the same timing question as a staking reward: when income arises and at what value.

What it changes

Crypto terms sit on top of rules written for assets with a location. Whether a holding is a foreign account, foreign property, or neither, follows from where the platform is and how the holding is characterised — and the position taken should be documented at the time.

Where the two countries disagree

A definition that is settled at home may be contested in the other country, or may exist there under a different name with different consequences. That is why we identify the governing system before applying the term rather than after.

Where you will actually see it

Putting it to work

If this term has turned up in a letter, a slip or an adviser's email and you are not sure which side of it you are on, that is a short call to the helpline rather than a research project. Bring last year's returns and we will tell you what is missing.

A definition earns its place only when it changes a decision. The ones on this site were chosen because each of them alters a filing, a deadline or a piece of evidence somewhere in a cross-border file, and the term pages say where.

Case study 1

Sorting a wallet of unsolicited tokens into reportable arrivals

A client's wallet had collected dozens of tokens they had never sought, some tradeable, most not. We went through them one at a time, establishing for each whether a value could be observed on the day it arrived and what evidence supported that. Tokens that could not be transferred at all were recorded with the searches that showed it. The engagement produced a schedule of arrivals with a valuation conclusion and its evidence beside each line, and a short note of the method used, so the same approach carries into later years.

Case study 2

Choosing between the allocation date and the claim date

Tokens had been allocated to the client in one year and claimed by signing a transaction in the next, and the two dates gave very different values. We set out what the client could and could not do with the tokens between those dates, drawing on the project's own documentation, and settled on a single receipt point with the reasoning recorded. The engagement produced a dated position note and a schedule applying that position to every claim the client had made, so the returns for both years rest on the same reading.

Case study 3

Tokens that arrived before a move and were sold after it

A client received an airdrop while resident in one country and sold the tokens after becoming resident in another. Nothing in the file established what the tokens were worth on arrival, which is what decides how much of the movement belongs to each system. We reconstructed the arrival date and value from wallet and market records, and documented the characterisation on both sides. The engagement produced an arrival valuation supported by contemporaneous sources and a disposal computation for the country of sale that starts from it.

Case study 4

Restating a sale that ignored the value taken into income

An earlier return had reported airdropped tokens as income on arrival and then, on sale, reported the full proceeds as gain. The income already taxed had simply not been carried into the cost of the tokens. We tied each disposal to the arrival it came from, adjusted the cost base and restated the computation. The engagement produced a corrected disposal schedule and a single register covering arrivals and sales, so no amount can be counted twice in the years still open.

Case study 5

Answering questions from an authority about token arrivals

A client received a query about credits into a wallet that the authority had treated as unexplained receipts. We assembled a wallet-level record showing which entries were airdrops, which were transfers between the client's own addresses, and which were disposals, and set out the valuation method that had been applied to arrivals. The engagement produced a written reply with a transaction-level annex, and the file now holds the method note that made that reply possible to write in the first place.

Case study 6

Deciding whether an airdropped holding was reportable foreign property

A client held airdropped tokens through a platform established outside their country of residence and wanted to know whether the holding attracted foreign asset reporting as well as an income entry. The answer depended on how the arrangement was characterised and where the platform sat, so we examined the terms governing the client's claim on the tokens. The engagement produced a dated characterisation note and a reporting position applied consistently to both of the client's returns, with the terms relied on kept alongside it.

Case study 7

The Same Income Taxed Twice on Paper

Relief usually exists and is lost to sequence: one country taxes at source and the other credits it, and preparing them in the wrong order claims a credit against a figure nobody has computed.

Case study 8

Deduction at Source on Deposit Interest, Recovered

Where the treaty rate is lower than what was deducted, the difference comes back through a return rather than at source. The file establishes entitlement and files for the years still open.

Core International & Cross-Border Tax Services

International Tax Planning & Advisory

Strategy and compliance for income, assets and families spread across borders.

One coordinating team: filings on every side of the border are sequenced so treaty relief and foreign tax credits are claimed once — and in the right country.

U.S. & Cross-Border Tax Returns

Dual filers: U.S. citizens in Canada and Canadians with U.S. income run two parallel systems — we prepare both, in the right order, every year.

Expat & Emigration Tax

The move year is its own project: the elections and valuations filed that year decide the next decade of both countries’ returns.

Non-Resident Canadian Tax

Default withholding is 25% of gross: elective returns routinely turn over-withheld rent and pensions into refunds.

Transfer Pricing & BEPS

Documentation prepared with the return is the cheapest insurance in international tax; reconstructing it during an audit is the most expensive.

Cross-Border Estates & Trusts

Wills drafted for one country routinely misfire in the other — deemed disposition here, estate tax there, credits in between.

Cross-Border Corporate Tax

Expansion raises the same four questions every time — entity, PE, repatriation, payroll. We answer them before the tax authorities do.

India Tax for NRIs & Returning Residents

The deduction is taken on the sale price, not the gain — which is why an NRI property sale strands cash unless the certificate is applied for before closing.

Canadian Tax with a Foreign Element

Residency is decided on facts, not on a form — and the year you arrive or leave is the one where the largest amounts turn on the smallest details.

UAE Tax for Expats & Their Home Country

A zero-tax country is only half the answer — the question that decides the bill is whether the country you came from still treats you as resident.

Investment Funds & Holding Companies

Holding structures live or die on treaty access, beneficial ownership and substance — the MLI's principal-purpose test now sits over every arrangement.

A holding structure is only as good as its reporting. Foreign affiliates, accrued passive income and distributions each carry their own return, and the penalties on those attach to the form rather than to any tax being owed — so a structure that saves tax can still cost money if the information returns are late.

More on Airdrop

Do I have to report an airdrop I never asked for?

The starting point is that tokens received without consideration raise an income question at the moment they arrive, whether or not you wanted them. What makes unsolicited tokens different is that many have no market you could sell into, so the real issue is less whether to report and more what value to report. Work through the wallet token by token: separate those with an ascertainable value at receipt from those with none, and record the evidence for each. A short schedule with the reasoning written beside it turns an awkward wallet into a defensible position.

Is an airdrop taxed when it appears or when I claim it?

That is the timing question this term carries, and there is no single settled answer, so it should be documented rather than assumed. Allocation, appearance in a wallet, and a claim transaction you sign yourself can fall in different months or different years. Look at what you actually controlled at each stage; whether the tokens could be moved or sold before the claim usually drives the argument. Pick a position, write down the facts that support it, and use the same position for every airdrop rather than choosing whichever date suits the year.

How do I value an airdrop with no trading market?

If nothing trades, there may be no ascertainable value at receipt, and saying so with evidence is a position rather than a gap. Record what you looked for and when: whether any venue quoted the token, whether transfers were possible at all, and what the token fetched in any observable transaction. Keep the exports you relied on, because this is exactly the kind of fact nobody can reconstruct a year later. If a market appears afterwards, that bears on the later disposal rather than retrospectively on the receipt, and the schedule should show both dates.

What if airdropped tokens are worthless or cannot be sold?

Illiquid and worthless are different findings and should be recorded differently. A token you cannot move at all is a poor candidate for a receipt value; a token that trades thinly has a value that is merely hard to establish. Neither is a reason to leave the arrival out of the record. List the token, the date it appeared, what you found about its market and the conclusion you drew. If it is later abandoned or becomes tradeable, the same schedule carries that next event, which is what stops the history being rebuilt from memory.

Do airdrops need reporting in both countries I file in?

Each system applies its own rules to the same arrival, so both returns may have something to say about it, and they may not say it in the same year. Two separate questions arise. First, the income question: when each system treats the tokens as received, and at what value. Second, whether the holding itself falls inside either country's foreign asset reporting, which follows from where the platform or wallet arrangement sits and how the holding is characterised. Settle the characterisation once, in writing, and apply it to both returns rather than letting each adviser choose.

What cost base do I use when I sell airdropped tokens?

Whatever value you brought into income at receipt becomes the cost of those tokens, so a later sale is measured from that point rather than from nothing. Where the conclusion was that there was no ascertainable value on arrival, the cost is correspondingly low and the eventual disposal carries almost the whole movement, which is a consistent answer rather than a contradiction. What cannot work is reporting income on arrival and then computing the sale as though the tokens had cost nothing. Keep the arrival schedule and the disposal schedule together so each sale points back to its receipt.

Is double taxation illegal?

It is legal. Two countries can each have a valid claim on the same income — one because the income arose there, the other because you live there — and nothing prohibits both from exercising it. What exists instead is relief: tax treaties allocate the claim, and domestic law gives a credit for foreign tax paid. The relief is not automatic, though. It is claimed on a return, and unclaimed relief is simply lost. See how double taxation is relieved.

I work remotely from another country for a company back home — who taxes me?

Usually the country you are physically in, because employment income is generally sourced where the work is done, with your residence country taxing it as well if you are resident there and giving credit. Three things follow: your employer may acquire withholding and social security obligations where you sit, a treaty tie-breaker may be needed if both countries call you resident, and a short trip that becomes a long stay can cross a residence threshold nobody was watching.
