Corporate income tax (CIT)

Checked against official sources
Rate

20% general rate (Art. 357(2)(5)). There is no special CIT rate for subsoil users. Other rates: 25% for second-tier banks (except lending to businesses) and for gambling; 3% for agricultural producers; 6% for agricultural co-operatives; 5% in 2026 and 10% from 2027 for the social sphere. Branch profits tax on a non-resident's permanent establishment: 15% (Art. 689). Business losses carry forward for 10 years (Art. 339).

Base
Taxable income: aggregate annual income minus deductions (with adjustments), reduced by losses carried forward.
Who pays
Resident legal entities, including subsoil users, and non-residents operating through a permanent establishment. A subsoil user keeps separate tax accounts and computes CIT separately for each subsoil use contract (Art. 757).
Legal reference
Tax Code 2026: Art. 357 (rates); Art. 339 (10-year loss carry-forward); Art. 689 (15% branch profits tax); Arts. 742–743 and 756 (complex projects); Art. 757 (separate accounting per contract)
What changed in 2026

The 20% general rate is unchanged (old Code Art. 313). New sectoral rates were added: 25% for banks and gambling, 3%/6% for agriculture, and 5%→10% for the social sphere. As before, there is no oil & gas CIT rate. Loss carry-forward is still 10 years (old Art. 300).

Mineral extraction tax (MET) on oil — crude oil and gas condensate

Checked against official sources
Rate

2026 (Art. 778(1)(1)), by the contract's planned annual production: up to 250 kt 5%; up to 500 kt 7%; up to 1 Mt 8%; up to 2 Mt 9%; up to 3 Mt 10%; up to 4 Mt 11%; up to 5 Mt 12%; up to 7 Mt 13%; up to 10 Mt 15%; over 10 Mt 18%. Oil sold or delivered domestically (Kazakh refineries, tolling, own use, in-kind) gets a 0.5 coefficient. From 1 January 2027 (Art. 778(1)(2)), a volume × world price matrix applies (columns 20…200 USD/bbl). Rates run from 19% (up to 250 kt at up to 40 USD) to 67% (over 10 Mt at 190 USD). Domestic oil then gets an equalising coefficient instead of 0.5.

Base
Value of the oil produced in the quarter (Arts. 775–776). Marketable oil, including exports: volume × world price. The world price is the average of daily quotes ((min+max)/2) for Urals Med (CIF Augusta), KEBCO (CIF Augusta) or Brent Dtd from Argus Crude (fallback: S&P Global), multiplied by the average official exchange rate. For Urals/KEBCO contracts, the higher of the two prices applies. Barrels convert to tonnes with the weighted-average barrelisation coefficient from quality passports. Sales to Kazakh refineries: the refinery's actual purchase price. Tolling and own use: production cost +20%. In-kind payment: a price set by the Government. The State Revenue Committee (KGD) publishes the world price by the 10th of the following month.
Who pays
Subsoil users producing hydrocarbons, contract by contract (Art. 773). It does not apply where a stabilised pre-2009 PSA or Presidential-contract regime governs (Art. 755(1)), or where the alternative subsoil use tax applies instead (Art. 812).

What changed in 2026

In 2026 the 5–18% scale and the 0.5 coefficient are the same as in old Code Art. 743. New: the world price now also uses KEBCO (previously only Urals Med and Brent Dtd), and relief is limited to low-margin fields under the new Resolution No. 1024. From 2027 the export rent tax and export duty burden moves into MET: the rate depends on both volume and price (19–67%). Domestic oil gets an equalising coefficient instead of 0.5; an MNE draft proposes delaying it to 2030.

MET on raw gas (natural and associated)

Checked against official sources
Rate

10% standard rate (e.g. exported raw gas). Domestic sales, by annual production: up to 1.0 bcm 0.5%; up to 2.0 bcm 1.0%; over 2.0 bcm 1.5% (Art. 778(1)). The 2027 matrix applies to oil only.

Base
Marketable gas, including exports: volume × Zeebrugge Day-Ahead world price (Platts European Gas Daily; fallback Argus European Natural Gas) × average exchange rate. Domestic sales: weighted-average sales price. Own use, and associated gas used to make LPG: production cost +20%. Flared gas: the maximum wholesale price cap for commercial gas. Gas reinjected to raise oil recovery within the project documents is exempt.
Who pays
Subsoil users producing raw gas (per contract).

Rent tax on export (RTE) of crude oil and gas condensate

Checked against official sources
Rate

One rate on the full value, set by the world price (USD/bbl, inclusive): up to 20: 0%; up to 30: 0%; up to 40: 0%; up to 50: 7%; up to 60: 11%; up to 70: 14%; up to 80: 16%; up to 90: 17%; up to 100: 19%; up to 110: 21%; up to 120: 22%; up to 130: 23%; up to 140: 25%; up to 150: 26%; up to 160: 27%; up to 170: 29%; up to 180: 30%; up to 190: 32%; up to 200 and above: 32% (Art. 749). Quarterly: pay by the 25th and file by the 15th of the second month after the quarter.

Base
Export value: actual export volume × world crude price (Art. 776(3)). The per-barrel price converts to a per-tonne price with the weighted-average barrelisation coefficient from quality passports at the start of the export route (Art. 748). Volume is taken from box 35 of the goods declaration, or from the acceptance act for EAEU destinations (Art. 747).
Who pays
Exporters of crude oil and crude products, except volumes produced under Art. 755(1) contracts or by AST payers. In 2026, MET-paying subsoil users also pay it, because Art. 835 suspends their exclusion. From 1 January 2027, volumes produced by hydrocarbon MET payers are excluded (Art. 746).

Export customs duty (ECD) on crude oil

Checked against official sources
Rate

Below 25 USD/bbl: 0. From 25 to 105 USD/bbl: ECD (USD/t) = average price (USD/bbl) × 1 (e.g. 76 USD/bbl → 76 USD/t). Above 105 USD/bbl, by table: 105–115: 115 USD/t; 115–125: 130; 125–135: 145; 135–145: 160; 145–155: 176; 155–165: 191; 165–175: 206; 175–185: 221; 185 and above: 236 USD/t. Actual rates reported (KGD data, press): August 2026 76 USD/t; September 2026 94 USD/t (average 94 USD/bbl for 20.07–20.08.2026).

Base
Tonnes exported. The monthly rate is set from the average market price for the preceding period (20th of the month two months back to the 20th of the prior month). The price is the average of daily ((min+max)/2) KEBCO and Brent quotes from Argus Crude (fallback S&P Global). KGD publishes it by the 28th.
Who pays
Declarants exporting crude oil from Kazakhstan. Exemptions (Rules para 8): exports to countries with exemption treaties (EAEU etc.); pre-01.01.2009 PSAs with an exemption; contracts with an exemption (except royalty payers); offshore Caspian fields (except complex projects) from 2027 when the price is below 95 USD (2027–2031), 100 USD (2032–2036), 105 USD (2037–2041) or 110 USD (from 2042); complex projects for 20 years (offshore and onshore gas) or 10 years (onshore) from first export. Gas condensate (HS 2709 00 100 0) is not on the list.
Legal reference
This is not a Government resolution. Governing act: Order of the Minister of Trade and Integration of RK of 17 April 2026 No. 169-НҚ 'On approval of the List of goods subject to export customs duties, their rates and validity, and the Rules for calculating export customs duty rates on crude oil and oil products' (Appendix 1 Section 2; Appendix 2 Rules, paras 3–8 and Annex 2). It takes effect 10 calendar days after first official publication (reported as 4 May 2026). Basis: sub-para 2-1) of Art. 7 of the Law 'On regulation of trade activities'. It superseded MNE Order No. 81 of 17 February 2016 (reg. No. 13217), formally repealed by MTI Order No. 228-НҚ of 29 July 2026.

A new Order No. 169-НҚ was approved in 2026, making Argus Crude the mandatory price source. The ECD abolition built into the 2027 MET scale has not been enacted as of September 2026.

Excess profit tax (EPT)

Checked against official sources
Rate

Sliding scale by tier (net income as % of deductions): up to 25% not taxed; 25–30% 10%; 30–40% 20%; 40–50% 30%; 50–60% 40%; 60–70% 50%; over 70% 60% (Art. 808).

Net income = contract taxable income (gross annual income less EPT deductions) minus contract CIT, and for a permanent establishment also minus branch profits tax (Arts. 801–806). EPT deductions = CIT-deductible expenses plus actual capital expenditure in the period instead of depreciation (Art. 804). Excess deductions carry forward (Art. 802(2)).
Who pays
Subsoil users, per contract (Art. 799). Not payable by parties to Art. 755(1) contracts, by holders of contracts for solid and common minerals, groundwater and therapeutic mud (if no other minerals are covered), or by underground-structure contracts. AST payers pay the AST instead.
