Kazakhstan has a bilateral income tax treaty with the United States, which primarily serves to reduce withholding taxes on cross-border investment income. However, there is no social security totalization agreement, a critical fact for self-employed Americans who remain fully liable for US self-employment taxes. Due to the treaty's saving clause, US citizens are generally taxed on their worldwide income, making the Foreign Tax Credit and Foreign Earned Income Exclusion the main tools for avoiding double taxation on salary and business profits.
US filing basics every American abroad must know
US citizens and green-card holders are taxed on worldwide income wherever they live, and usually must file Form 1040 once gross income exceeds the IRS threshold ($15,750 for single filers, $31,500 for married filing jointly, and $23,625 for head of household for 2025), even when no tax is ultimately due. The tools that reduce double taxation are the Foreign Earned Income Exclusion (FEIE, up to $130,000 for 2025 under IRC §911) and the Foreign Tax Credit. Neither is automatic. The FEIE requires a tax home in a foreign country plus either the bona fide residence test or 330 full days abroad in a 12-month period, and it reaches earned income only. The Foreign Tax Credit is figured separately for each income category under IRC §904 and is capped at the US tax on the foreign income in that category, so it reduces double taxation without guaranteeing that none remains.
Two reporting rules catch most filers in Kazakhstan: the FBAR (FinCEN Form 114), required when foreign financial accounts exceed $10,000 in aggregate at any point in the year, and Form 8938 (FATCA) for specified foreign assets above the applicable threshold. Both can carry penalties even when no tax is owed. If you are behind, the Streamlined Filing Compliance Procedures are the usual path back for non-willful taxpayers. They run on two tracks: the foreign track carries no offshore penalty but requires meeting the program's non-residency test, and the domestic track carries a 5% offshore penalty but works through amended returns, so it does not fit someone who never filed at all. Tax and interest on the catch-up years are owed whichever route applies.
US tax treaty with Kazakhstan
The US-Kazakhstan income tax treaty, signed in 1993 and effective from January 1, 1996, aims to prevent double taxation and fiscal evasion. Its most practical effects for a US citizen living in Kazakhstan are the reduction of Kazakh withholding tax on dividends, interest, and royalties paid from Kazakh sources. The treaty contains a saving clause, which permits the US to tax its citizens as if the treaty did not exist. Consequently, US citizens cannot use the treaty to exempt their Kazakh-source income from US tax; they must instead rely on mechanisms like the Foreign Tax Credit.
Article 1 (Saving Clause).
This is a standard feature of US tax treaties that reserves the right for the United States to tax its citizens and residents on their worldwide income, regardless of other treaty provisions. This clause significantly limits the ability of US citizens to use the treaty to reduce their US tax liability, with a few specific exceptions.
Article 10 (Dividends).
Sets the maximum withholding tax rate that Kazakhstan can impose on dividends paid to a US resident. The general rate is 15%, but it is reduced to 5% for corporate shareholders who own at least 10% of the paying company's voting stock.
Article 11 (Interest).
Caps the withholding tax rate on interest income paid from Kazakh sources to a US resident at 10%.
Article 12 (Royalties).
Caps the withholding tax rate on royalties paid from Kazakh sources to a US resident at 10%.
Article 21 (Limitation on Benefits).
This article is designed to prevent 'treaty shopping' by ensuring that only qualified residents of the US and Kazakhstan who have a substantial connection to the country can benefit from the treaty's provisions.
| Income type | Treaty rate | Statutory rate | Notes |
|---|---|---|---|
| Dividends | 15% | 15% | A 5% rate applies if the beneficial owner is a company that owns at least 10% of the voting stock of the company paying the dividends. |
| Interest | 10% | 15% | |
| Royalties | 10% | 15% |
Because of the saving clause, a US citizen living in Kazakhstan generally cannot use the treaty to exempt income from US tax. The treaty's main benefits are providing a framework for the Foreign Tax Credit, establishing residency tie-breaker rules, and lowering Kazakh withholding tax on payments made to the US person.
Kazakhstan's UAPF and US Tax Implications
Kazakhstan's mandatory pension system is the Unified Accumulative Pension Fund (UAPF), a defined contribution plan. For US tax purposes, the UAPF is not a 'qualified' plan like a 401(k). The IRS has published no guidance on the UAPF specifically, so whether a US person's interest in it is an interest in a foreign trust has to be worked out from the plan terms and the facts.
This has several significant reporting consequences:
- Form 3520: If the arrangement is a foreign trust, contributions and distributions may need to be reported on Form 3520 and Form 3520-A. Rev. Proc. 2020-17 exempts certain tax-favored foreign retirement trusts from both forms where its conditions are met, so check that relief before assuming the filings are due.
- FBAR and Form 8938: The UAPF account balance must be included when determining if you meet the filing threshold for the Report of Foreign Bank and Financial Accounts (FBAR). Form 8938 is a separate question: the Form 8938 instructions exclude an interest in a social security, social insurance, or similar program of a foreign government, and the UAPF is a mandatory state scheme, so whether it is a specified foreign financial asset turns on that exclusion.
- PFIC Reporting: The underlying investments within the UAPF are likely considered Passive Foreign Investment Companies (PFICs). This is a major complication, as it can require annual filing of Form 8621 for each underlying fund and may result in a punitive tax calculation on earnings and distributions unless specific, timely elections are made.
Investments, property, and capital gains in Kazakhstan
Investing in Kazakhstan presents several US tax complexities. Any investment in a Kazakh mutual fund, exchange-traded fund, or similar pooled investment vehicle is almost certainly a Passive Foreign Investment Company (PFIC). This triggers a burdensome reporting requirement on Form 8621 and a default tax regime that can be highly unfavorable. Capital gains on the sale of property or securities are taxable in the US, regardless of their treatment in Kazakhstan. US citizens are taxed on their worldwide capital gains, and the Kazakh flat tax rate may differ from the US long-term capital gains rates, impacting the calculation of the Foreign Tax Credit.
Self-employment and companies in Kazakhstan
If you own a significant stake (typically 10% or more) in a Kazakh business entity, such as a Limited Liability Partnership (LLP) or Joint Stock Company (JSC), it may be a Controlled Foreign Corporation (CFC) if US shareholders (those owning 10% or more) collectively own more than 50%. This classification requires the US shareholder to file Form 5471 annually, a complex information return. Furthermore, CFC rules could require you to include a portion of the company's earnings in your US taxable income under the GILTI (Global Intangible Low-Taxed Income) or Subpart F regimes, even if no distribution is made.
For self-employed individuals, the most critical fact is that there is no US-Kazakhstan social security totalization agreement. This means a self-employed US citizen in Kazakhstan is fully liable for US self-employment taxes (Social Security and Medicare) on their net earnings. This tax is 15.3% on 92.35% of net earnings, with the 12.4% Social Security portion stopping at the annual wage base ($176,100 for 2025) and the 2.9% Medicare portion uncapped, plus a further 0.9% Additional Medicare Tax on combined Medicare-taxed wages and self-employment income above $200,000 for a single, head-of-household or qualifying-surviving-spouse filer, $250,000 for a joint return, and $125,000 for married filing separately. It applies once net earnings from self-employment are $400 or more. You cannot obtain a Certificate of Coverage to claim an exemption, and you may be required to contribute to both the US and Kazakh social insurance systems simultaneously. The Foreign Earned Income Exclusion does not reduce income subject to self-employment tax.
Worked examples
Salaried IT Manager in Almaty (2025)
Sarah is a US citizen working for a Kazakh tech company, earning a salary of $120,000. She contributes 10% of her salary to the mandatory UAPF pension plan. For her US tax return, Sarah can use the Foreign Earned Income Exclusion (FEIE) if her tax home is in Kazakhstan and she meets either the 330-day physical presence test or the bona fide residence test. Her salary is under the 2025 limit of $130,000, so the exclusion can remove it from US income tax. However, her filing obligations are not zero. She must report her UAPF account on her FBAR and Form 8938 (assuming her balances exceed the thresholds). She also has a potential filing requirement for Form 3520 for her UAPF contributions and must consider the complex PFIC implications (Form 8621) of the UAPF's underlying investments.
Self-Employed Business Consultant (2025)
David is a US citizen living in Astana, working as a self-employed consultant. He has net earnings from self-employment of $100,000. Because there is no totalization agreement between the US and Kazakhstan, David must pay US self-employment tax. He calculates this tax on Schedule SE. For 2025, this would be 15.3% of 92.35% of his net earnings, totaling approximately $14,130 ($100,000 * 0.9235 * 0.153). This tax is due to the IRS even if he also pays into Kazakhstan's social insurance system. While he can use the FEIE to exclude the $100,000 from US income tax, the FEIE provides no relief from self-employment tax.
Retiree with Kazakh Investments (2025)
Linda is a US citizen retired in Kazakhstan. Her income consists of $20,000 in dividends from a Kazakh Joint Stock Company (JSC) and $10,000 in interest from a Kazakh bank. Kazakhstan withholds tax at the treaty rates: 15% on the dividends ($3,000) and 10% on the interest ($1,000). On her US return, Linda reports the full $30,000 of income. She can then claim a Foreign Tax Credit on Form 1116 for the $4,000 of taxes paid to Kazakhstan to offset her US tax liability on that same income. If she also holds units in a Kazakh investment fund, she must determine if it is a PFIC and file Form 8621, which could result in additional US tax beyond what is covered by her foreign tax credits.
Common mistakes for Americans in Kazakhstan
- Assuming a social security agreement exists and failing to pay US self-employment tax.
- Using the Foreign Earned Income Exclusion and incorrectly thinking it eliminates liability for US self-employment tax.
- Failing to report an interest in the UAPF pension plan on the FBAR, Form 8938, and Form 3520.
- Ignoring the Passive Foreign Investment Company (PFIC) rules for investments in the UAPF or other Kazakh mutual funds.
- Forgetting to file Form 5471 for a controlled Kazakh company, such as an LLP or JSC.
- Believing the US-Kazakhstan tax treaty allows a US citizen to exclude their salary from US tax (it does not, due to the saving clause).
- Failing to report worldwide income, such as capital gains from the sale of property outside Kazakhstan.
- Incorrectly calculating the Foreign Tax Credit by using a different definition of income than the IRS requires.
Kazakhstan tax FAQ
Is there a US-Kazakhstan Social Security agreement?
No. There is no social security totalization agreement between the United States and Kazakhstan. This means a self-employed US citizen in Kazakhstan is fully liable for US self-employment tax (Social Security and Medicare) and cannot use a Certificate of Coverage to avoid it, even if they also contribute to the Kazakh system.
How is my Kazakh pension (UAPF) treated for US tax purposes?
The UAPF is not a 'qualified' plan. It may be an interest in a foreign trust, though the IRS has issued no guidance on the UAPF specifically. Report it on the FBAR (FinCEN Form 114) if you meet that threshold; for Form 8938, the instructions exclude an interest in a foreign government's social security or social insurance program, so a mandatory state scheme may fall outside it. You may also need to file Form 3520 and Form 3520-A unless the relief in Rev. Proc. 2020-17 applies. Critically, its underlying investments are likely PFICs, which requires filing Form 8621 and can lead to complex and unfavorable tax treatment.
Do I have to pay US self-employment tax if I live and work in Kazakhstan?
Yes, if you are self-employed. Because there is no totalization agreement, you owe US self-employment tax of 15.3% on 92.35% of your net earnings, with the 12.4% Social Security portion stopping at the annual wage base ($176,100 for 2025) and the 2.9% Medicare portion uncapped. It applies once net earnings are $400 or more. Neither the Foreign Earned Income Exclusion nor the Foreign Tax Credit reduces this tax.
Can I use the tax treaty to avoid paying US tax on my Kazakh salary?
No. The treaty's 'saving clause' allows the US to tax its citizens on their worldwide income as if the treaty didn't exist. To avoid double taxation on your salary, you must use the Foreign Earned Income Exclusion (FEIE) or the Foreign Tax Credit (FTC), not the treaty itself.
What is a PFIC and why should I care in Kazakhstan?
A PFIC is a Passive Foreign Investment Company. Most foreign mutual funds, including the investments inside the Kazakh UAPF pension, are PFICs. Owning a PFIC requires filing Form 8621 annually and can result in very high US tax rates on earnings unless you make specific, timely elections. It is a major source of complexity for US expats.
I own part of a Kazakh LLP. What are my US filing obligations?
If you are a US person who owns 10% or more of a Kazakh Limited Liability Partnership (LLP) or Joint Stock Company (JSC), it may be a Controlled Foreign Corporation (CFC) if US shareholders (those owning 10% or more) collectively own more than 50%. This requires you to file the very complex Form 5471 each year and may cause some of the company's income to be taxed to you personally in the US, even if you receive no dividends.
What are the treaty withholding rates on income from Kazakhstan?
The US-Kazakhstan treaty limits the tax Kazakhstan can withhold on payments to a US resident. The rates are generally 15% for dividends (with a 5% rate for certain corporate owners), 10% for interest, and 10% for royalties.
Do I need to report my local Kazakh bank account to the US?
Yes, almost certainly. If the aggregate value of all your foreign financial accounts (including bank, brokerage, and pension accounts like the UAPF) exceeds $10,000 at any point during the year, you must file an FBAR (FinCEN Form 114). You may also need to file Form 8938 if you meet its higher balance thresholds.
