Mongolia Capital Gains Tax Guide 2026

Overview — CGT in Mongolia

Capital gains in Mongolia are included in the ordinary income of the taxpayer and taxed at the standard income tax rates. There is no separate capital gains tax schedule or preferential rate for long-term gains. For individuals, gains are aggregated with other income and taxed at the flat 10% IIT rate. For companies, gains are included in chargeable profits and taxed at 25% (standard) or 10% (small business). The disposal of assets includes sale, exchange, gift, transfer, or deemed disposal. The gain is calculated as proceeds minus acquisition cost and incidental costs of disposal.

Individual CGT — 10% Flat Rate

Individuals pay capital gains tax at the flat 10% IIT rate on net chargeable gains. The gain is included in the individual's annual income and taxed along with other income sources. The calculation is: Disposal proceeds minus (Acquisition cost + Incidental costs of acquisition and disposal + Enhancement expenditure). Allowable costs include the original purchase price, legal fees, valuation costs, registration fees, and capital improvements. The annual tax-free threshold of approximately MNT 4,800,000 may reduce the effective tax on smaller gains. Capital losses may be offset against capital gains in the same year, with unrelieved losses carried forward for up to 2 years.

MSE Share Exemption

Gains from the disposal of shares listed on the Mongolian Stock Exchange (MSE) may be exempt from capital gains tax under certain conditions. The exemption is designed to encourage investment in the Mongolian capital market. To qualify, the shares must be held for a minimum period (typically 1 year) and the seller must be a resident individual. The exemption does not apply to substantial shareholdings (generally 25% or more) or to gains from unlisted shares. The MSE has been developing as a capital market, with listings in mining, banking, and other sectors. The Financial Regulatory Commission (FRC) oversees the securities market.

Principal Residence Relief

Gain from the disposal of an individual's principal private residence is exempt from capital gains tax in Mongolia, provided the property has been owned and occupied as the main residence for a minimum period (typically 2 years). Partial relief is available where a property has been used partly as a residence and partly for business, or where the period of occupation covers only part of the ownership period. The relief covers the building and associated land. Additional residences (second homes, investment properties) are fully chargeable. The exemption applies to one property per individual.

Property & Real Estate Gains

Gains from the disposal of real property (land and buildings) are subject to capital gains tax at the standard rates. Mongolia has a land registration system under the State Registration Authority. Property gains are calculated as the difference between the sale price and the acquisition cost, adjusted for capital improvements. A withholding tax may apply on property transfers: the purchaser may be required to withhold a percentage of the purchase price and remit it to MTA as an advance payment against the vendor's final CGT liability. Property developers are taxed on property sales as business income rather than capital gains.

FAQs

How do I calculate my chargeable gain as an individual?

The chargeable gain is the difference between the disposal proceeds (net of selling costs) and the acquisition cost (plus enhancement expenditure and buying costs). Example: Buy land for MNT 100 million, sell for MNT 150 million, costs of MNT 5 million. Gain = 150,000,000 - 100,000,000 - 5,000,000 = MNT 45,000,000. IIT at 10% = MNT 4,500,000.

Can I offset capital losses against other income?

Capital losses may only be offset against capital gains in the same tax year. Unrelieved capital losses may be carried forward for up to 2 years but cannot be offset against other income (e.g., salary or business profits).

What assets are exempt from CGT?

Principal residence (subject to conditions), MSE-listed shares (for qualifying individuals), government securities, motor vehicles (personal use), and assets transferred on death (no deemed disposal).
