Mongolia does not have a dedicated cryptocurrency tax law
Cryptocurrency in Mongolia is treated as a form of property or digital asset subject to general income tax provisions.
The General Department of Taxation (GDT) applies the existing Income Tax Law of Mongolia (2019 revision) to profits generated from crypto trading and mining activity and gains from disposing of cryptocurrency are folded into an individual’s general taxable income rather than assessed under a separate capital gains framework.
Capital Gains Tax Rules
Mongolia does not operate a standalone capital gains tax regime. Instead, profits arising from the disposal of cryptocurrency are treated as part of an individual’s or entity’s ordinary income and taxed accordingly.
When an individual sells, trades, or otherwise disposes of cryptocurrency for a profit, that profit is aggregated with other income and taxed at the flat 10% personal income tax rate under the Income Tax Law of Mongolia (2019 revision).
How gains are calculated
Because gains are treated as ordinary income rather than capital gains, the taxable amount is effectively the profit realised on disposal: the proceeds received minus the cost of acquiring the cryptocurrency. Mongolia’s tax framework does not provide for holding period discounts or concessional rates based on the length of time an asset is held. Every disposal at a gain is fully taxable in the period in which it occurs.
Losses on crypto disposals may in principle reduce overall income, but as of 2025, the GDT has not issued specific guidance on the treatment of crypto losses or whether they can be offset against other income categories. Taxpayers should seek professional advice on this point.
Record keeping
Taxpayers are expected to maintain documentation supporting both the acquisition cost and the proceeds of each disposal. This means retaining exchange records, wallet transaction histories, receipts for crypto purchased, and any records of crypto received as payment. Because Mongolia’s crypto guidance remains relatively undeveloped, keeping comprehensive records protects taxpayers in the event of audit or inquiry by the GDT.
Income Tax Rules
Under the Income Tax Law of Mongolia, all income received by a resident individual is subject to the flat 10% personal income tax rate, and this includes income derived from cryptocurrency activity. When an individual receives cryptocurrency as payment for goods or services, or earns crypto through a business-like pattern of trading, the value of that crypto at the time of receipt constitutes taxable income.
For corporate entities conducting crypto trading or operating mining businesses, income is subject to corporate income tax at rates between 10% and 25%, tiered by income level. The GDT has confirmed through administrative guidance that digital asset income falls within the scope of the standard income tax rules. Businesses are expected to account for crypto receipts and gains in their normal corporate tax filings.
As of 2025, Mongolia has not issued specific guidance distinguishing between passive investment in cryptocurrency and active trading as a business, nor has it clarified the precise rules for valuing crypto income received in kind.
Taxpayers engaged in regular or high-volume crypto activity should treat such income conservatively as fully taxable in the period received, valued at the market rate at the time of the transaction.
Mining and Staking Treatment
Mining
Mining income in Mongolia is treated as ordinary taxable income under the Income Tax Law of Mongolia and the GDT’s administrative guidance on digital assets.
When a miner receives a block reward or transaction fee in cryptocurrency, that amount is considered income at the time of receipt, valued at the market rate of the asset on that date. The 10% personal income tax rate applies to individuals, while corporate mining operators are taxed at the applicable corporate rate.
From 2022, the government introduced specific electricity tariffs targeting mining operations and began requiring licences for large-scale mining activities.
Expenses directly associated with mining, such as electricity costs and hardware, may be deductible against mining income for businesses operating under a corporate or trading structure, but the GDT has not published detailed guidance on the scope of allowable deductions for individual miners.
Any subsequent disposal of mined cryptocurrency at a profit would constitute a further taxable event, with the cost base being the value at which the asset was brought to account as income.
Staking
As of 2025, Mongolia has not issued specific guidance on the taxation of staking rewards.
In the absence of dedicated rules, staking income would most likely be treated in the same manner as other forms of crypto income: taxable at receipt, valued at the prevailing market rate, and subject to the 10% flat PIT for individuals. This interpretation aligns with the GDT’s general approach of applying standard income tax principles to digital asset activity.
When staked assets are later sold or disposed of, any gain over the value at which the staking reward was originally brought to account as income would constitute a further taxable event. Taxpayers engaged in staking should maintain records of each reward received, including the date and the value of the asset at that time, to support accurate calculation of both the income component and any subsequent gain.
NFT Taxation
Mongolia has not issued any specific guidance on the taxation of non-fungible tokens (NFTs).
In the absence of dedicated rules, the GDT’s general approach of applying standard income tax principles to digital assets would likely extend to NFTs as well. For individuals buying and selling NFTs as investments, any gain on disposal would be included in taxable income and subject to the 10% personal income tax rate.
Where an individual or business creates and sells NFTs commercially, the income received would be treated as ordinary business or trading income, taxable in the period received at the applicable income tax rate. The cost of producing the NFT, including any associated platform fees or costs of the underlying digital content, may be deductible as business expenses, though again, specific guidance on this point has not been issued.
As of 2025, Mongolia has not addressed whether VAT applies to NFT transactions. Given that general VAT rules apply at 10% but specific crypto and NFT carve-outs have not been enacted, businesses transacting in NFTs at scale should seek professional advice on their VAT obligations.
Reporting Requirements
Individuals in Mongolia must report all taxable income, including income and gains from cryptocurrency, through the standard personal income tax return process administered by the GDT.
Income is calculated on an annual basis, and individuals are required to self-assess and file their returns, reporting all sources of income including any crypto profits. Corporate entities report crypto income through their standard corporate tax filings.
All income and gains must be converted to Mongolian togrog (MNT) for reporting purposes, using the exchange rate applicable at the time of the transaction. Taxpayers should use a consistent and verifiable source for exchange rate data, such as the Bank of Mongolia’s published rates.
Taxpayers are also expected to retain records supporting all reported figures, including transaction logs from exchanges, wallet histories, bank records related to crypto purchases or sales, and any documentation of crypto received as payment. There is no formally prescribed minimum record retention period specific to crypto, but it is prudent to retain records for at least the general statutory period applicable to tax matters.
As of 2025, Mongolia does not operate a formal data-matching programme between the GDT and crypto exchanges equivalent to those seen in more developed crypto tax jurisdictions. However, the government’s increased attention to mining operations from 2022 onwards indicates a growing enforcement interest in the broader crypto sector.
Penalties
Mongolia’s tax administration under the GDT provides for penalties in cases of non-compliance, including failure to report taxable income or underreporting of amounts owed.
Penalties for non-disclosure or underreporting of income, including crypto income, can include financial penalties calculated as a percentage of the unpaid tax, as well as interest charges accruing on outstanding amounts until the liability is settled.
The severity of penalties typically reflects the nature and degree of the non-compliance. Deliberate concealment of income attracts more serious consequences than inadvertent error.
As of 2025, the GDT has not published detailed crypto-specific penalty guidance, but the general penalty framework under the tax administration law applies equally to digital asset income.
Taxpayers who identify errors or omissions in previously filed returns are generally better positioned by coming forward voluntarily rather than waiting for an audit to uncover the issue.
Voluntary disclosure, where a taxpayer proactively corrects a prior underreporting, typically attracts a more favourable outcome than non-compliance identified through enforcement action. Taxpayers with uncertain positions on crypto income should seek professional advice and consider regularising their position proactively.
