# Oil Gas Extractives

## What this file is

A sector overlay for oil & gas, mining, and other extractives companies.

## Section 1 — Fiscal regimes overview

**[T1] Three main regime models**  _(Section 1 — Fiscal regimes overview)_

| Regime | Mechanism | Examples |
| --- | --- | --- |
| **Concession / Royalty + Tax** | Operator pays royalty + standard CIT (often ring-fenced) | UK (Brent, North Sea), Norway, US (federal + state royalty + CIT), Canada, Australia |
| **Production Sharing Contract (PSC)** | Operator recovers costs from "cost oil/gas"; "profit oil/gas" split with government per scale | Indonesia, Nigeria, Angola, Egypt, Algeria, Brazil pre-salt, Kazakhstan |
| **Service / Risk Service** | Operator paid fee per unit produced; government retains ownership | Mexico (pre-2014 reform), Iran (buyback), Iraq (technical services contract) |

## Section 2 — UK North Sea fiscal regime

### 2.1 The ring-fence

- **UK ring-fence rule** — UK upstream petroleum activities are "ring-fenced" — losses and profits from non-ring-fence trades cannot offset ring-fence profits.  _([T1])_

### 2.2 Three taxes

- **Ring-Fence Corporation Tax (RFCT)** — 30%  _(Finance Act 2002)_
- **Supplementary Charge (SC)** — 10% additional tax (reduced from 32% in 2016, reinstated to 10% in 2024)  _([T1])_
- **Energy Profits Levy (EPL)** — 35% (rate increased to 38% from 1 November 2024 under Finance Act 2025 amendments; sunset extended to March 2030)  _(Energy Profits Levy Act 2022; Finance Act 2025)_
- **Total effective rate** — 30% + 10% + 38% = 78% (post-November 2024)  _([T1])_
- **Petroleum Revenue Tax (PRT)** — frozen at 0% from 2016 for new fields  _([T1])_

### 2.3 Allowances

- **Capital allowances** — 100% first-year on most plant and machinery in ring-fence  _([T1])_
- **Loss carryforward / carryback** — intricate  _([T1])_
- **EPL investment allowance** — 44% (reduced from 80%) for qualifying ring-fence investment expenditure  _([T1])_

## Section 3 — Norwegian Special Tax

- **Standard CIT** — 22%  _([T1])_
- **Special petroleum tax (SPT)** — 56% (effective rate)  _([T1])_
- **Combined marginal rate** — 78%  _([T1])_
- **Cash-flow basis tax reform** — Recently introduced cash-flow basis for tax reform: full first-year deduction of qualifying upstream investment (reformed 2022); SPT calculated on operating cash flow less qualified investment expense  _([T1])_

## Section 4 — EU Solidarity Contribution

- **Temporary solidarity contribution** — Temporary solidarity contribution on fossil fuel sector "surplus profits"  _(Council Regulation (EU) 2022/1854)_
- **Surcharge rate** — 33% surcharge on profits above 120% of 4-year average  _(Council Regulation (EU) 2022/1854 (October 2022))_
- **Member State implementation** — Member States implemented as temporary windfall taxes for 2022 and 2023  _([T1])_
- **Extension and UK treatment** — Most Member States extended through 2024-2025; UK has its own EPL outside EU framework  _([T1])_

## Section 5 — US oil and gas

- **Federal CIT** — 21%  _([T1])_
- **State CIT** — variable  _([T1])_
- **Severance taxes** — state-level on extracted product (Texas oil severance 4.6%; Oklahoma 7%; ND 6.5%; WV 5%; etc.)  _([T1])_
- **Royalty** — federal lease 18.75% offshore / 12.5% onshore (raised from 12.5% to 16.67% in 2022 reform); state and private lease rates negotiated  _([T1])_
- **IDC (Intangible Drilling Costs)** — election to expense currently (§263(c))  _(§263(c))_
- **Depletion allowance** — percentage depletion for small producers (§613A) or cost depletion (§612)  _(§613A; §612)_
- **Successful Efforts vs Full Cost** — financial accounting method choice (ASC 932)  _(ASC 932)_

### 6.1 Major mining jurisdictions

**Major mining jurisdictions**  _(Section 6 — Mining sector)_

| Country | Royalty | CIT | Notable |
| --- | --- | --- | --- |
| **Australia** | Mineral Resources Rent Tax (MRRT) repealed 2014; state royalties (NSW, QLD, WA variable 2-10%) | 30% CIT; full expensing of capital | Major iron ore, coal, gold |
| **Canada** | Provincial royalty + CIT 26.5% combined | Federal 15% + provincial | Major potash, oil sands |
| **Chile** | Mining royalty (2024 reform: ad-valorem + margin-based 1-2% + 10-32% on profits above thresholds) | 25% CIT | World's largest copper |
| **Peru** | Mining royalty 1-12% by margin; Special Mining Tax 2-8.4% on operating margin; CIT 29.5% | 29.5% | Major copper, gold, zinc |
| **South Africa** | Mining royalty 0.5-7% by refined vs unrefined | 27% CIT (post-2024) | Major platinum, gold |
| **Indonesia** | Royalty 3-6% by mineral; PSC for oil/gas | 22% CIT | Major coal, nickel |

### 6.2 EITI (Extractive Industries Transparency Initiative)

- **EITI reporting** — 50+ implementing countries publish reconciled extractive payments and receipts. EU Accounting and Transparency Directives require listed extractive companies to publish payments to governments (Country-by-Country Reporting equivalent).  _([T1])_

### 7.1 Successful Efforts vs Full Cost

- **Successful Efforts** — only successful exploration costs capitalised; dry holes expensed.  _([T1])_
- **Full Cost** — all exploration and development costs capitalised in "cost pool" by country.  _([T1])_
- **GAAP/IFRS treatment** — US GAAP ASC 932 permits both. IFRS 6 (Exploration and Evaluation Assets) allows choice for E&E phase but development phase aligned to IAS 16 / IAS 38.  _(ASC 932; IFRS 6; IAS 16; IAS 38)_

### 7.2 Asset Retirement Obligation (ARO) / Decommissioning

- **ARO recognition** — IAS 37 / ASC 410: provision for future decommissioning recognised at discounted PV of cost when constructive obligation arises (typically at first production).  _(IAS 37; ASC 410)_
- **Provision accounting treatment** — Provision debited as asset addition; depleted with the reserve  _([T1])_
- **Tax deduction timing** — Tax deduction generally only when actually incurred (jurisdiction-specific)  _([T1])_
- **Deferred tax impact** — Material deferred tax timing difference  _([T1])_

### 7.3 Reserves estimation (PRMS)

- **Petroleum Resources Management System** — 1P (proved), 2P (proved + probable), 3P (proved + probable + possible). Recoverable reserves drive depletion accounting.  _([T1])_

## Section 8 — Pillar Two interaction

- **Pillar Two complexity for extractives** — Extractives jurisdictions with low CIT but high royalty/severance face Pillar Two complexity: - Royalty is typically treated as "Covered Tax" if levied on income (some jurisdictions classify as production tax, ambiguous) - Severance taxes mostly NOT Covered Taxes - Carve-out for "International Shipping Income" exists; no equivalent for extractives - Substance-Based Income Exclusion (SBIE) particularly material for capital-intensive extractives  _([T1])_
