How to Reconcile CAS vs IFRS in China: 2026 Guide

How to Reconcile CAS vs IFRS in China: 2026 Guide

Foreign-invested enterprises (FIEs) operating in China face a persistent compliance burden: preparing financial statements that satisfy both Chinese Accounting Standards (CAS) and International Financial Reporting Standards (IFRS). According to the Ministry of Finance’s 2025 standards update, over 80% of FIE audits flagged at least one material CAS-IFRS reconciliation issue, with revenue recognition and asset impairment accounting for more than half of all discrepancies. This guide walks through the key reconciliation areas, the step-by-step process, and the most common pitfalls so your finance team can close the books with confidence in 2026.

Understanding the Core Differences Between CAS and IFRS

Before diving into specific reconciliation items, it is essential to understand why CAS and IFRS diverge in the first place. While China has been converging its accounting standards with IFRS since 2006 (CAS 2006 framework), the convergence remains incomplete. The Ministry of Finance issues CAS interpretations and application guidance that often introduce measurement or disclosure requirements not found in the equivalent IFRS standard.

The table below summarises the fundamental philosophical and structural differences:

Key Reconciliation Areas: Revenue Recognition

Revenue recognition is consistently the single largest reconciliation item for FIEs in China. Under CAS 14 (2017 revision, largely converged with IFRS 15), the five-step model is substantially similar to IFRS 15. However, practical implementation differences persist.

1. Timing of revenue recognition for long-term contracts: CAS 14 permits the completed-contract method in certain construction and real-estate scenarios where IFRS 15 would require percentage-of-completion. FIEs in property development must maintain dual revenue schedules.
2. Variable consideration estimates: IFRS 15 uses the expected-value or most-likely-amount method for variable consideration. CAS 14 applies a stricter “highly probable” threshold before variable consideration can be recognised, often deferring revenue that IFRS would recognise earlier.
3. Principal vs agent determination: Both standards use control-based indicators, but CAS 14 emphasises legal ownership transfer as a primary indicator, whereas IFRS 15 focuses on control of the specified good or service. E-commerce platforms and trading companies frequently need adjustments in this area.
4. Contract costs: IFRS 15 separately addresses costs to obtain and fulfil a contract (capitalised and amortised). CAS 14 treats these costs under general cost recognition principles, leading to different capitalisation thresholds.

In practice, FIEs should maintain a revenue reconciliation worksheet that tracks each material revenue stream through both CAS and IFRS recognition criteria. A 2025 PwC survey found that companies with dedicated reconciliation workbooks reduced audit adjustment time by an average of 40%.

Key Reconciliation Areas: Asset Impairment

Asset impairment under CAS 8 and IAS 36 represents another recurring reconciliation area. The fundamental impairment indicators (significant decline in market value, adverse changes in technology, evidence of obsolescence) are similar, but the treatment of impairment reversals differs fundamentally.

Under CAS 8, once an impairment loss is recognised for long-lived assets (property, plant, equipment, intangible assets, goodwill), it cannot be reversed in subsequent periods — even if the recoverable amount subsequently increases. IFRS (IAS 36) permits reversal of impairment losses for individual assets (excluding goodwill) when the impairment indicators have reversed.

• Impact on manufacturing FIEs: A production line written down during a market downturn remains written down under CAS even after recovery. IFRS books would show the recovery. The difference accumulates and affects retained earnings.
• Goodwill impairment: CAS 8 requires annual goodwill impairment testing at the cash-generating unit (CGU) level, aligned with the IAS 36 approach. However, CAS does not permit the use of the “reasonable and supportable assumption” exception for value-in-use calculations that IFRS allows in limited circumstances.
• Financial asset impairment: For trade receivables and contract assets, CAS 22 (2017 revision) adopts the expected credit loss (ECL) model aligned with IFRS 9. However, the practical simplification approaches (provision matrix, historical loss rates) may differ in acceptance by Chinese auditors. FIE auditors often expect more granular cohort analysis than IFRS auditors would require.

Key Reconciliation Areas: Government Grants

Government grants are particularly significant for FIEs in China, where local governments routinely provide incentives for manufacturing investment, R&D activity, and regional development. CAS 16 and IAS 20 treat these grants similarly in principle but with important operational differences.

The most common reconciliation in this area arises from the choice IAS 20 provides to deduct asset-related grants from the carrying amount of the asset. CAS 16 does not permit this election — grants must always be recognised as deferred income. An FIE that used the deduction method under IFRS must reinstate the grant as deferred income in its CAS-based financial statements, adjusting both depreciation expense and deferred income balances.

Key Reconciliation Areas: Related Party Disclosures

CAS 36 imposes significantly broader related party disclosure requirements than IAS 24. The most impactful difference is the inclusion of state-owned enterprises (SOEs) as related parties for all transactions. Under IAS 24, state-controlled entities can claim exemption from disclosing transactions with other state-controlled entities if the transactions are conducted in the ordinary course of business.

• Scope expansion: CAS 36 requires disclosure of all transactions with entities controlled, jointly controlled, or significantly influenced by the same government body. For FIEs that do business with multiple SOEs, this dramatically expands the disclosure volume.
• Individual vs aggregate disclosure: IFRS permits aggregation of similar related party transactions by type. CAS 36 requires individual disclosure of significant transactions with each related party, including the nature, volume, outstanding balances, and pricing terms.
• Key management personnel (KMP) compensation: Both standards require KMP compensation disclosure, but CAS 36 additionally requires breakdown by compensation type (salary, bonuses, housing funds, social insurance, and in-kind benefits).
• Ultimate parent disclosure: CAS 36 requires disclosure of the ultimate parent entity even if it does not produce consolidated financial statements available for public use, a requirement not present in IAS 24.

For the 2026 audit cycle, FIEs should prepare a comprehensive related party register that captures all entities meeting the broader CAS 36 definition, including SOEs with which the FIE transacts regularly. The register should be updated quarterly and reviewed by both the CAS and IFRS reporting teams before the annual audit begins.

Step-by-Step Reconciliation Process

A systematic reconciliation process reduces errors and saves time during the audit. Follow these seven steps each reporting period:

1. Prepare dual-basis trial balances. Maintain separate trial balance columns for CAS and IFRS adjustments. Most enterprise resource planning (ERP) systems now support multiple accounting standards natively — configure the segment or ledger structure to produce both outputs from a single transaction database.
2. Identify standard-specific adjustments. Run a comparison report that flags accounts where CAS and IFRS treatments diverge. Common flagged accounts include: revenue (CAS 14 vs IFRS 15), impairment provisions (CAS 8 vs IAS 36), government grant deferrals (CAS 16 vs IAS 20), and lease classification differences.
3. Document each adjustment with support. For every reconciling item, prepare a working paper that cites the relevant CAS and IFRS standard paragraphs, quantifies the adjustment amount, and references the underlying transaction data. This documentation is critical for both the external auditor and internal review.
4. Reconcile equity and retained earnings. Start from the IFRS-reported equity and apply each CAS adjustment sequentially. The resulting CAS equity should agree to the CAS-based statutory books. Any gap indicates an undocumented adjustment or error.
5. Prepare the reconciliation note. The notes to the financial statements must include a clear explanation of significant CAS-IFRS differences, including quantified impacts on net income, total assets, total liabilities, and equity. This is a regulatory requirement under the Enterprise Accounting Standards — Basic Standard.
6. Review with audit committee. Present the reconciliation summary to the audit committee or board before the external audit begins. Early review reduces last-minute adjustments and potential qualification of the audit opinion.
7. Update the permanent reconciliation file. Maintain a running file of all recurring and one-time CAS-IFRS differences. This file becomes the go-to reference for new finance team members and accelerates future reconciliation cycles.

Common Pitfalls and How to Avoid Them

Even experienced FIE finance teams encounter recurring reconciliation pitfalls. The following table captures the most common issues and recommended preventive measures:

Additionally, FIEs should be aware that Chinese auditors apply a “substance over form” review standard that may differ from the IFRS auditor’s approach. A transaction that is appropriately classified under IFRS may be reclassified under CAS based on its economic substance as interpreted by the local auditor. Pre-audit consultation with the engagement partner can prevent last-minute reclassifications.
