Foreign companies with a China subsidiary routinely run two sets of books: the statutory accounts prepared under Chinese Accounting Standards for local filing, and the reporting figures their overseas parent consolidates under IFRS or US GAAP. The two frameworks are close — China deliberately converged its standards with IFRS — but they are not identical, and the remaining differences surface in exactly the places finance teams care about, from asset impairment to government grants to the format of the financial statements themselves. This guide explains what CAS is, how it differs from IFRS, and what those differences mean for statutory reporting, annual audit, and group consolidation.
Key Takeaways
- Chinese Accounting Standards (CAS) are substantially converged with IFRS but retain differences in impairment, government grants, and statement presentation.
- A China subsidiary’s statutory books must be maintained under CAS in RMB, and its annual audit is conducted against those standards.
- Under CAS, impairment losses on fixed assets and intangibles cannot be reversed, while IFRS generally permits reversal.
- Foreign parents typically prepare reconciliation adjustments when consolidating CAS statutory figures into IFRS or US GAAP group accounts.
- Corporate income tax in China is calculated on tax-adjusted profit, so CAS results are the starting point rather than the tax base.
Key Facts
- Standard-setter: The Ministry of Finance, through the Accounting Standards for Business Enterprises.
- Statutory bookkeeping currency: RMB, with the financial statements prepared in Chinese.
- Impairment: CAS prohibits reversal of fixed asset and intangible impairment; IFRS allows it (except goodwill).
- Inventory: LIFO is prohibited under both CAS and IFRS.
- Revenue and leases: CAS has largely converged with IFRS 15 and IFRS 16.
- Tax link: China corporate income tax applies to tax-adjusted profit, not directly to CAS book profit.
What Are Chinese Accounting Standards (CAS)?
Chinese Accounting Standards, formally the Accounting Standards for Business Enterprises, are the accounting rules issued by China’s Ministry of Finance that all Chinese companies — including foreign-invested enterprises — must follow for their statutory financial statements. CAS covers recognition, measurement, presentation, and disclosure across the full range of reporting topics, from revenue and leases to financial instruments and consolidation. There is also a separate, simpler set of standards for small business enterprises, but a foreign subsidiary of any meaningful size will normally report under the full standards.
For a foreign parent, the practical consequence is that the China subsidiary’s local accounts are not optional reporting preferences. They are the basis of the company’s statutory bookkeeping, its monthly and annual filings, and its statutory annual audit. The statutory books are kept in RMB and the financial statements are prepared in Chinese, which is why many overseas groups engage a local firm such as Dan Young to run the bookkeeping, audit and tax function and to translate and bridge the numbers for group reporting.
How Converged Are CAS and IFRS?
China began aligning its accounting standards with IFRS in the mid-2000s and has continued that process. As a result, CAS is now substantively converged with IFRS on many of the topics that matter most. Revenue recognition under CAS follows the same five-step, performance-obligation model as IFRS 15. Lease accounting under CAS has adopted the single lessee model of IFRS 16, bringing most leases onto the balance sheet. Business combinations, consolidation, and borrowing costs are all closely aligned with their IFRS equivalents.
The convergence, however, is not complete. A few areas are deliberately different, either because China retained a domestic approach or because the Ministry of Finance has not yet adopted a newer IFRS amendment. The differences are narrow but real, and they are concentrated enough that a finance team preparing a first-time consolidation should map them out rather than assume the CAS statements can be dropped into group reporting unchanged.
The Key Differences Foreign Companies Should Know
Impairment of fixed assets and intangibles. This is the single most significant practical difference. Under CAS, once an impairment loss is recognized on property, plant and equipment or on intangible assets, it cannot be reversed in a later period even if the asset’s recoverable amount recovers. IFRS, by contrast, permits the reversal of impairment on such assets, excluding goodwill. A group consolidating under IFRS therefore often needs an adjustment where a Chinese subsidiary has written down an asset that has since recovered value.
Government grants. CAS and IFRS both allow a grant related to an asset to be presented either as deferred income or as a deduction from the carrying amount of the asset, and both recognize income-related grants in profit or loss on a systematic basis. The models are broadly aligned, but the presentation choices made locally can differ from the parent’s policy and may need to be reclassified on consolidation.
Financial statement presentation. China prescribes a standardized chart of accounts and a specific format for the balance sheet, income statement, and cash flow statement. IFRS is more principles-based about presentation. A subsidiary’s CAS statements therefore tend to follow a fixed template that may not map one-to-one onto the parent’s IFRS reporting package, requiring line-by-line reclassification rather than a simple currency translation.
Small-entity standards. Where a subsidiary qualifies as a small enterprise, it may use the separate Accounting Standards for Small Business Enterprises, which are simpler than full CAS and not aligned with IFRS. A parent relying on those simpler local statements for group purposes usually needs to adjust them upward to full IFRS.
Related party and disclosure detail. Disclosure requirements around related parties and segment-style information differ in places from IFRS, though these differences are generally narrower than the measurement differences above.
What This Means for Statutory Reporting and Consolidation
In practice, a foreign parent should expect three distinct outputs from its China subsidiary. The first is the statutory CAS financial statements in RMB and Chinese, prepared for local filing and audit. The second is the tax computation, which starts from the CAS result but applies China’s specific tax adjustments to arrive at taxable profit for corporate income tax. The third is a reconciliation package that converts the CAS statements into the parent’s IFRS or US GAAP basis, applying the impairment, grant, and presentation adjustments described above.
Getting the third output right matters as much as the first two, because a parent that simply re-denominates the CAS numbers in its reporting currency risks misstating group profit, equity, and asset values. Finance teams that plan for this from day one — by establishing a clean CAS chart of accounts, mapping it to the group’s account codes, and documenting the standard adjustments — find the monthly and year-end close far smoother than teams that treat the China entity as an afterthought. Dan Young’s bookkeeping, audit and tax service prepares the statutory CAS books, supports the statutory audit, and produces the bridge schedules foreign parents need for consolidation, with the same discipline captured in the company’s compliance calendar.
Frequently Asked Questions
Are Chinese Accounting Standards the same as IFRS?
No. CAS is substantially converged with IFRS on revenue, leases, and consolidation, but it is not identical. The main differences are that CAS does not allow the reversal of fixed asset and intangible impairment, and China prescribes a more standardized format and chart of accounts than IFRS.
Do foreign companies in China have to use CAS?
Yes. A foreign-invested enterprise must keep its statutory books under Chinese Accounting Standards, in RMB, and prepare its statutory financial statements in Chinese. These statements form the basis of the annual statutory audit and local filings.
What is the biggest difference between CAS and IFRS?
The most significant practical difference is impairment. Under CAS, impairment losses on fixed assets and intangible assets cannot be reversed once recognized, whereas IFRS generally permits reversal except for goodwill. This commonly requires an adjustment when a parent consolidates its China subsidiary.
Is China corporate income tax based on CAS profit?
No. China corporate income tax is calculated on taxable profit, which starts from the CAS accounting result and then applies China’s specific tax adjustments. The CAS financial statements are the starting point for the tax computation, not the tax base itself.
How should a foreign parent consolidate its China subsidiary?
The parent should start from the CAS statutory statements and apply a documented reconciliation package that converts them to IFRS or US GAAP, covering impairment reversal differences, government grant presentation, and statement format reclassification, rather than simply translating the RMB figures.
