Introduction
If you are the CFO or financial controller of a foreign company with a subsidiary in China, you face a recurring challenge: your Chinese WFOE maintains its statutory books under Chinese Accounting Standards (CAS, also known as Chinese GAAP), while your parent company reports under International Financial Reporting Standards (IFRS) or another home-country GAAP. Reconciling the two — accurately, completely, and on time for group consolidation — is not optional. It is a core compliance obligation.
China has made significant progress in converging CAS with IFRS over the past two decades, and for many transactions the two frameworks now produce identical results. But substantial differences remain — particularly in areas like asset impairment, revenue recognition timing, related-party disclosures, and government grant accounting. Misunderstanding these differences can lead to consolidation errors, audit qualifications, and in the worst case, tax authority challenges.
This guide explains the key differences between CAS and IFRS that matter most for foreign parent companies consolidating Chinese subsidiaries, with practical advice for financial controllers operating in Guangzhou, Shenzhen, and across Guangdong.

CAS and IFRS: A Convergence Story
In 2006, China’s Ministry of Finance issued a substantially new set of Accounting Standards for Business Enterprises (ASBEs) — commonly referred to as Chinese Accounting Standards (CAS) — that were explicitly designed to achieve substantial convergence with IFRS. The 2006 CAS was described by the IASB as a “significant step” toward alignment. Further revisions in 2014, 2017, and 2019 have continued the convergence process.
Today, CAS is largely modeled on IFRS in structure and content. The numbering of CAS standards broadly follows IFRS/IAS numbering, and the conceptual framework — definitions of assets, liabilities, income, and expenses — aligns closely with the IFRS Conceptual Framework.
However, convergence is not adoption. Important differences persist for three reasons:
- China’s legal and economic environment: Certain IFRS principles do not translate directly to China’s regulatory framework, particularly in areas where government policy plays a role (e.g., government grants, state-owned enterprise accounting).
- Deliberate policy choices: In a few areas, China has consciously chosen a different treatment — most notably the prohibition on reversing impairment losses on long-lived assets, which IFRS permits.
- Transition timing: China sometimes delays adoption of new IFRS standards to allow time for domestic implementation preparation. For example, IFRS 17 (Insurance Contracts) took longer to implement in China than in many IFRS jurisdictions.
For the foreign parent company, the bottom line is: CAS is close to IFRS, but not identical. You cannot assume that a CAS-compliant financial statement automatically complies with IFRS. A reconciliation is necessary.
Asset Impairment: The Biggest GAAP Difference
The single most consequential difference between CAS and IFRS — and the one that most frequently generates consolidation adjustments — is the treatment of asset impairment reversals.
Under IFRS (IAS 36), when circumstances change and the recoverable amount of a previously impaired asset increases, the impairment loss is reversed (subject to the carrying amount not exceeding what it would have been absent the original impairment). This applies to goodwill as well under certain circumstances in previous versions of IFRS, though current IFRS prohibits goodwill impairment reversal.
Under CAS, once an impairment loss is recognized on a long-lived asset — including property, plant and equipment, intangible assets, and goodwill — that impairment can never be reversed. The prohibition is absolute and permanent. The Chinese standard-setters’ rationale is to prevent earnings management through impairment reversals, which was a known abuse in pre-2006 Chinese accounting.
For a foreign subsidiary in Dongguan or Foshan that has recognized an impairment on manufacturing equipment or factory buildings, this means the asset will remain at the impaired carrying amount in the CAS books indefinitely, even if market conditions improve. When consolidating into IFRS group accounts, the parent company must reverse the impairment for group reporting purposes — creating a permanent GAAP difference in the consolidation working papers.
This difference is particularly significant for manufacturing WFOEs and companies with substantial fixed asset bases, as it can materially affect reported net assets and profitability ratios in the statutory Chinese financial statements.
Revenue Recognition: Subtle Timing Differences
Both CAS 14 (Revenue) and IFRS 15 (Revenue from Contracts with Customers) now follow the same five-step revenue recognition model, and for most routine transactions — sale of goods, provision of services at a fixed price — the results are identical.
However, differences can arise in specific areas:
- Principal vs. agent determination: CAS guidance on the principal-versus-agent assessment is less detailed than IFRS 15’s indicators. In complex multi-party arrangements (common in China’s trading and distribution sector), financial controllers may reach different conclusions under CAS and IFRS about whether to recognize revenue on a gross or net basis.
- Licensing revenue: CAS provides less detailed implementation guidance on the distinction between right-to-use and right-to-access licenses, which can affect revenue recognition timing for software, media, and intellectual property licensing arrangements.
- Contract modifications: IFRS 15 contains detailed guidance on accounting for contract modifications (changes in scope or price). CAS 14 addresses the topic but with less granularity, and Chinese practice tends toward more conservative (later) revenue recognition on modified contracts.
- Variable consideration: While both standards require estimating variable consideration using either the expected value or most likely amount method, CAS guidance is less permissive regarding the inclusion of variable consideration when uncertainty is high. Chinese auditors typically apply a higher threshold of certainty before allowing variable consideration to be recognized.
For most WFOEs engaged in straightforward trading, manufacturing, or consulting services, revenue recognition under CAS and IFRS will produce the same result. But companies with complex contracts, multi-element arrangements, or significant variable consideration should scrutinize this area during the consolidation process.
Government Grants: China’s Unique Accounting Treatment
China’s approach to government grant accounting differs from IAS 20 in ways that frequently affect foreign subsidiaries, particularly those in development zones or incentive programs.
Under IAS 20, government grants are recognized in profit or loss on a systematic basis over the periods in which the entity recognizes the related costs. Grants related to assets are presented either as deferred income or as a deduction from the carrying amount of the asset.
CAS 16 is broadly aligned with IAS 20 but with important practical differences:
- Stricter recognition criteria: CAS requires that the entity has actually received the grant funds (or has a legally binding commitment) before recognition. A government approval letter alone is generally insufficient under CAS, whereas IAS 20 permits recognition when there is reasonable assurance of receipt.
- Asset-related grants: CAS 16 provides a specific option to net the grant against the asset’s carrying amount (the “gross vs. net” election), but the election is constrained by Chinese regulatory practice. Some local authorities in Guangzhou, Shenzhen, and other cities effectively require a specific treatment as a condition of the grant.
- Tax treatment interaction: Government grants in China are often taxable upon receipt unless specific tax exemption rules apply. The interaction between the CAS accounting treatment and the tax treatment requires careful tracking of deferred tax assets and liabilities that may differ from the IFRS position.
For WFOEs that have received investment incentives, R&D subsidies, or operational grants — common in Nansha Free Trade Zone in Guangzhou, Qianhai in Shenzhen, and industrial parks in Dongguan — the timing difference between CAS and IFRS grant recognition can create material consolidation adjustments.
Inventory Valuation and LIFO Prohibition
Both CAS and IFRS require inventory to be measured at the lower of cost and net realizable value. Both permit FIFO and weighted average cost methods. Both prohibit LIFO.
The difference lies in practice: Chinese tax law requires consistency between tax and accounting inventory valuation methods. A change in inventory costing method for financial reporting purposes may trigger tax authority scrutiny unless the change is also reported to and accepted by the tax bureau. This creates a practical constraint — Chinese subsidiaries are less likely to change inventory valuation methods than their IFRS counterparts because of the administrative burden of the tax filing.
For manufacturing WFOEs in Dongguan, Foshan, and Jiangmen, this means the inventory valuation method selected at incorporation is likely to remain in place for years. It should be chosen with care and align with both Chinese tax efficiency and IFRS group policy from the outset.
Lease Accounting: IFRS 16 vs CAS 21
Both IFRS 16 (Leases) and the revised CAS 21 require lessees to recognize most leases on the balance sheet as right-of-use assets and lease liabilities. In this respect, CAS is fully converged with IFRS.
However, subtle differences exist in the practical application guidance:
- Low-value asset exemption: IFRS 16 provides a specific exemption for leases of low-value assets (e.g., laptops, office furniture). CAS 21 is less explicit about what constitutes “low value,” and Chinese practice tends toward a narrower interpretation — fewer leases qualify for the exemption under CAS than under IFRS.
- Discount rate: IFRS 16 requires the lessee to use the interest rate implicit in the lease if readily determinable; otherwise, the lessee’s incremental borrowing rate. CAS 21 is similar, but in China, where bank lending rates are influenced by policy and market rates can differ from the parent company’s group borrowing rate, determining the “incremental borrowing rate” for a Chinese subsidiary can be more complex. Chinese auditors often expect the rate to reflect the subsidiary’s own borrowing capacity in the Chinese credit market, not the parent company’s global cost of capital.
- Lease modifications: The IFRS 16 guidance on lease modifications (changes in scope or consideration) is more detailed than CAS 21’s, and Chinese practice tends toward simpler — sometimes more conservative — treatment.
For WFOEs with significant office leases in Guangzhou or Shenzhen (where commercial rents are high and lease liabilities material), the lease accounting differences can affect the balance sheet and key ratios reported in the statutory financial statements compared to the IFRS consolidation.
Related-Party Transactions and Disclosures
Both CAS 36 (Related Party Disclosures) and IAS 24 require disclosure of related-party relationships, transactions, and outstanding balances. The definition of “related party” is broadly similar.
However, CAS disclosure requirements are, in some respects, more extensive than IFRS:
- State-owned enterprise exemptions: IAS 24 provides a partial exemption from related-party disclosure requirements for transactions with government-related entities. CAS 36 provides a narrower exemption, and many transactions with state-owned enterprises that would be exempt under IFRS require disclosure under CAS.
- Pricing disclosures: CAS requires disclosure of the pricing policy for related-party transactions. This is particularly important in China, where the tax authorities closely scrutinize related-party pricing for transfer pricing compliance. The CAS disclosure should be consistent with the contemporaneous transfer pricing documentation maintained by the company.
- Disclosure of key management compensation: Both standards require disclosure, but CAS requires more granular breakdown of compensation categories (salaries, bonuses, social insurance contributions, housing fund, etc.) than IAS 24.
For foreign companies with complex intercompany arrangements — management service fees, royalty payments, intercompany loans — the CAS related-party disclosures must be carefully aligned with IFRS and with the transfer pricing documentation. Inconsistencies between these three documents are a red flag for Chinese tax auditors.
Financial Instruments: Classification and Measurement
CAS 22 (Financial Instruments: Recognition and Measurement) is substantially converged with IFRS 9. The classification model — amortized cost, fair value through other comprehensive income (FVOCI), and fair value through profit or loss (FVTPL) — is the same. The expected credit loss (ECL) impairment model for financial assets is the same.
The practical difference lies in implementation: IFRS 9’s ECL model requires significant judgment in estimating forward-looking expected credit losses. Chinese auditors, accustomed to a more prescriptive regulatory environment, often expect more conservative ECL provisions than would be typical under IFRS 9 in other jurisdictions. A trade receivable from a related party that might be assessed as having a low ECL under IFRS could attract a higher provision under CAS because Chinese auditors apply a higher default probability assumption.
Additionally, CAS does not include the specific hedge accounting simplifications present in IFRS 9 for certain common hedging relationships. Companies with active hedging programs (currency hedging, commodity hedging) may find that hedge accounting documentation under CAS is more burdensome than under IFRS.
Practical Reconciliation: A Month-End Workflow
For financial controllers managing a Chinese subsidiary from overseas, the monthly CAS-to-IFRS reconciliation should follow a structured process:
- Start with the CAS trial balance: The Chinese subsidiary’s accounting team closes the books under CAS and produces a trial balance, typically within 5 to 7 working days after month-end.
- Identify GAAP differences: Apply a pre-defined checklist of known CAS-IFRS differences. Common adjustments include: (a) reversal of asset impairment where IFRS permits but CAS prohibits; (b) adjustment to revenue recognition timing for complex contracts; (c) government grant reclassification; (d) ECL provision adjustments; and (e) lease-related measurement differences.
- Post GAAP adjustment journal entries: Record the IFRS adjustments in the consolidation system (not in the Chinese statutory ledger, which must remain CAS-compliant).
- Calculate deferred tax impact: Each GAAP difference that affects the carrying amount of an asset or liability creates a temporary difference requiring a deferred tax adjustment under IAS 12.
- Translate to reporting currency: Apply the group’s foreign currency translation policy (typically closing rate for the balance sheet, average rate for the income statement under IAS 21).
- Document in consolidation working papers: Maintain a clear audit trail showing each CAS-to-IFRS adjustment, the basis for the adjustment, and the quantification.
For WFOEs where the GAAP differences are small (a trading company with few fixed assets, no government grants, and simple revenue contracts), the reconciliation may be a 30-minute exercise each month. For manufacturing WFOEs with significant fixed assets, government grants, and complex intercompany arrangements, the reconciliation can be a multi-hour exercise requiring dedicated finance team attention.
Statutory Audit and Filing Requirements in China
All foreign-invested enterprises in China must prepare annual statutory financial statements in accordance with CAS and have them audited by a Chinese-registered CPA firm. The statutory audit report is filed with SAMR, the tax bureau, the foreign exchange authority, and (in some cases) the Ministry of Commerce.
The statutory audit serves two purposes: compliance with Chinese company law and tax regulations, and verification of the company’s registered capital and foreign exchange position. The Chinese auditor will express an opinion on the CAS financial statements — not on the IFRS adjustments. However, the auditor will typically review the IFRS reconciliation as part of understanding the company’s group reporting process, and inconsistencies between the CAS filings and the IFRS consolidation will be questioned.
For foreign parent companies, this creates a deadline-driven challenge: the Chinese statutory audit typically must be completed by April 30 (for the calendar year ending December 31), while the group audit deadline may be earlier or later depending on the parent company’s jurisdiction. Coordination between the Chinese statutory auditor and the group auditor is essential, and many foreign companies engage a firm like Dan Young that can liaise with both the Chinese audit team and the parent company’s global auditor.
Frequently Asked Questions
Can a Chinese WFOE prepare its statutory financial statements under IFRS instead of CAS?
No. Chinese company law and accounting regulations require all enterprises in China — including foreign-invested enterprises — to maintain their statutory books and prepare their statutory financial statements in accordance with CAS. IFRS can be used for internal management reporting and group consolidation, but the statutory filing must be in CAS.
Is the CAS-to-IFRS reconciliation audited?
The Chinese statutory auditor does not directly audit the IFRS reconciliation. However, the group auditor (e.g., a Big Four firm at the parent company level) will review the reconciliation as part of the group audit, and material errors in the reconciliation can result in group-level audit adjustments or qualifications.
Which CAS-IFRS differences are most likely to be material?
Asset impairment (where IFRS permits reversals and CAS does not) and government grant recognition timing are the two most frequently material differences for manufacturing and incentivized WFOEs. For service companies with few fixed assets, the differences are typically immaterial.
Does the tax return follow CAS or IFRS?
The Chinese Corporate Income Tax (CIT) return starts from the CAS-compliant accounting profit and then applies tax adjustments as prescribed by the Enterprise Income Tax Law. The starting point is always CAS, never IFRS. This means that GAAP differences affecting accounting profit also affect the tax reconciliation, creating deferred tax implications.
What qualifications should our Chinese bookkeeping provider have?
The provider should be a licensed accounting firm registered with the Chinese Institute of Certified Public Accountants (CICPA) or a qualified accounting services agency. Ideally, the provider should have experience with foreign-invested enterprises and be familiar with IFRS consolidation requirements to prepare the reconciliation efficiently.
