Taxes in Kazakhstan: how much, when, Form 270.00

Which tax and why

A tax resident of Kazakhstan pays individual income tax (IIT) on all their income, including income earned abroad. The State Revenue Committee (KGD) classifies income from forex trading through a foreign broker as “other income from sources outside the Republic of Kazakhstan”. There's no need to register as a sole proprietor for such trading.

The Kazakhstan IIT is usually not withheld for the trader by anyone: neither the foreign broker nor the bank on withdrawal. Calculating, declaring and paying it is the trader's own duty. A separate story is foreign tax withheld at source, which happens on some kinds of income, for example dividends on real shares. Where there's proof, it can be credited, and that's covered at the end of the article.

The rate

From 1 January 2026 a new Tax Code (No. 214-VIII of 18.07.2025) is in force. Article 363 introduces a progressive scale: annual income up to 8,500 MCI is taxed at 10%, and the part of income above the threshold at 15%. In 2026 the MCI equals 4,325 tenge, and the threshold is 36,762,500 tenge a year. Income for 2025 and earlier is taxed at a flat 10%, without progression.

Dividends have their own scale (5% up to 230,000 MCI), which has nothing to do with trading income.

Tax on the trade result, not on withdrawal

The IIT liability is tied to realised income: the trade is closed, the result recorded to the trading account. Floating profit on still-open positions is not yet income. Two practical consequences:

• If there's a profit but the money has stayed with the broker, the tax still has to be declared and paid. The KGD warns explicitly: keeping income in foreign accounts does not exempt it from tax.
• An incoming transfer from abroad is not in itself taxed. Withdrawing your own previously deposited money is not income. You deposited $5,000, traded to a loss, withdrew the remaining $2,000: there's no object of taxation in the transfer of that $2,000 itself. Whether income remains within such a loss-making year depends on how the trade result is calculated: see below.

Income in a foreign currency is converted into tenge at the market rate on the last business day before the date on which the income becomes due: that's how it's worded in the KGD's clarifications.

How and when to declare

Form 240.00, still mentioned by old articles online, has been abolished starting with 2025 income. Income from abroad now goes into the income-and-assets declaration, Form 270.00:

• who must file: Article 417 of the Tax Code, including everyone who received income taxed on a self-assessed basis. Forex income is exactly that;
• filing deadline: no later than 15 September of the year following the reporting one (Article 418 of the Tax Code);
• payment deadline: no later than 10 calendar days after the filing deadline, that is by 25 September (Article 419 of the Tax Code).

Besides income, the duty to file Form 270.00 arises for those who have more than 1,000 MCI in total on foreign bank accounts as of 31 December (4,325,000 tenge in 2026), for owners of foreign real estate, securities, company stakes and digital assets, and also on large purchases above 20,000 MCI.

The entry Form 250.00 is not needed by everyone: the obligation depends on the taxpayer category in the universal-declaration rules. Anyone who has already filed 250.00 does not file it again.

The declaration can be filed electronically: the Taxpayer's Cabinet, eGov, the e-Salyq Azamat app. Payment details: BCC 101202, KNP 911.

What happens if you don't declare

• Failure to file a declaration (art. 272 of the Administrative Offences Code): a warning the first time, and for a repeat offence within a year a fine of 15 MCI (64,875 tenge in 2026).
• Concealing an object of taxation (art. 275 of the Administrative Offences Code): a fine of 200% of the tax on the concealed object, 300% on repeat. Plus a penalty for each day the payment is late.
• A separate fine for concealing foreign assets and money in foreign bank accounts that should have entered the declaration: 100 MCI (art. 275, part 3 of the Administrative Offences Code).
• Since 2021 Kazakhstan has received data on residents' foreign accounts under the CRS standard from dozens of countries, and not only from banks but also from brokers and investment companies. For undeclared foreign income the KGD sends notices: in 2023 alone more than 1,600 went out.

If tax was withheld abroad

Tax paid in another country can be credited against Kazakhstan IIT within the Kazakhstan rate, but a document from the foreign tax authority will be needed. For forex and CFD brokers this is usually not relevant: they don't withhold tax on trading income.
