The short answer
No double tax agreement has a digital-asset article. Treaties were drafted around categories established long before these assets existed, and relief requires mapping your income onto one of those categories.
The mapping is an analysis, not a lookup. The same receipt can be characterised differently by two treaty partners, and where that happens the treaty may fail to prevent double taxation — which is the outcome the taxpayer is trying to avoid.
Two structural points before the detail. Treaties allocate taxing rights between countries; they do not create a charge, and they do not exempt income from a country that has no claim in the first place. And treaty benefits generally have to be claimed, with documentation, and sometimes with disclosure on a return.
The articles that matter
Business profits. Where the activity is an enterprise, profits are generally taxable only in the residence state unless there is a permanent establishment in the other state. For crypto this raises the question of what constitutes a permanent establishment — servers, mining facilities, and staff locations are the usual candidates, and a mining operation with physical infrastructure in another country is the clearest case.
Capital gains. Most treaties assign taxing rights over gains on property other than defined categories — immovable property, business property of a permanent establishment, and certain shares — to the residence state. Digital assets typically fall into the residual category, pointing to residence-state taxation. That is helpful, but it depends on the treaty's actual wording and on which categories it enumerates.
Interest. Where a return is genuinely interest on a debt claim, the interest article applies, usually with a reduced withholding rate. Whether a lending protocol return is interest for treaty purposes is not obvious: there may be no identifiable debtor, no debt claim in the conventional sense, and no counterparty at all.
Dividends. Rarely relevant, though tokens conferring rights resembling equity participation raise the question.
Royalties. Occasionally argued for certain licence-like arrangements. Usually a poor fit.
Income from employment. Tokens received as employment reward are employment income, allocated by reference to where the services were performed, with the usual conditions on short-term presence.
Other income. The residual article, typically assigning taxing rights to the residence state. Many crypto receipts that do not fit elsewhere land here — which is often the taxpayer's best available position, and which is also why the residual article's presence and wording in a specific treaty is worth checking.
Where mapping breaks down
Staking rewards. Are they interest, business profits, or other income? A country treating them as interest may withhold. A country treating them as other income may not. If the two countries characterise the same receipt differently, both may tax it, and the treaty's relief mechanism may not engage cleanly.
DeFi returns. The absence of an identifiable counterparty makes several articles awkward to apply. There is often no payer to withhold, no residence of a payer to establish, and no contractual relationship of the kind the articles assume.
Mining. Business profits if it is an enterprise, with the permanent establishment question determining where. Hobby-scale mining may fall into other income.
Airdrops. Frequently no counterparty and no consideration. Other income is the usual landing point, if any article applies at all.
Relief mechanisms
Where both countries tax the same income, treaties provide relief either by exemption in one country or by credit for tax paid in the other. The mechanism differs by treaty and by income type, and credit relief is usually capped at the residence country's tax on that income.
Where characterisation differs between the countries — the conflict-of-qualification problem — relief can fail. The remaining route is the mutual agreement procedure, under which the competent authorities of the two countries attempt to resolve the case. It is slow, and it should be understood as a real but expensive backstop rather than a routine remedy.
Claiming benefits
- Establish residence for treaty purposes, including applying the tie-breaker where you are resident in both.
- Obtain a certificate of residence where the other country requires one.
- Provide the correct documentation to any payer before payment, since recovering over-withheld tax afterwards is far harder than preventing it.
- Make any required disclosure on the return, which in some countries is a specific form and carries penalties if omitted.
- Retain the analysis supporting your characterisation, dated.
Worked example
An individual resident in Country A receives staking rewards through a platform in Country B, and separately disposes of tokens at a gain.
The disposal: residual capital gains treatment points to Country A as residence state, subject to the treaty's actual wording and to any source rule Country B applies.
The rewards: characterisation must be established in both countries. If Country B treats them as interest with withholding and Country A treats them as other income taxable only in Country A, the taxpayer faces withholding that Country A may credit only partially, or a claim for refund in Country B under the treaty.
Neither answer is obvious from the treaty text alone, which is the honest state of this area.
What changes this answer
- The specific treaty and its wording, which differ significantly between agreements.
- Whether a treaty exists at all between the two countries.
- Characterisation in each country.
- Whether a permanent establishment exists.
- Anti-abuse provisions, including principal-purpose tests introduced through the multilateral instrument.
- Domestic law in both countries, which determines the charge the treaty then allocates.

Evidence note
This page describes how treaty articles are generally structured and does not state the terms of any specific agreement. Not professionally reviewed. Characterisation of protocol returns for treaty purposes is unsettled and disputed between jurisdictions. Where material amounts are involved, obtain advice in both countries and check the actual text of the treaty concerned, including any modifications made by the multilateral instrument.
