Managing Book-Tax Differences for China Annual CIT Filings

Book-tax difference management is a significant task for financial managers and auditors during the annual corporate income tax (CIT) reconciliation season in China. This reconciliation season, also called the annual CIT filing, must be completed by May 31 of each year. If companies do not properly address book-tax differences, they may suffer unnecessary tax losses and penalties. Seeking professional assistance is advisable for companies that are not familiar with book-tax differences in China.

Book-tax difference pertains to the inconsistencies between the accounting standards (CAS) and tax laws in China. Essentially, it implies that the tax treatment and the timing of recognition specified by the tax laws diverge from the accounting treatment prescribed by the accounting standards, in straightforward language.

The differences between the accounting standards and tax laws in China result from the different objectives that they serve. Accounting aims to accurately and truthfully reflect the financial situation of an enterprise, while tax laws mainly aim to ensure the tax revenue of the jurisdiction. Therefore, the two regulatory systems differ in accounting elements and measurement principles.

Paying attention to book-tax differences is crucial for companies to maintain tax compliance in China. The fundamental principle of taxation in China is that a company is taxed on its “income before tax.” This implies that the net value of “taxable income,” which is determined by subtracting authorized expenses and costs from the overall revenue, is taxable. Nevertheless, the income before tax is not always identical to the CAS-compliant net profits recorded in the accounting books.

Not recognizing these disparities could lead to underpaid taxes and a host of potential consequences, such as penalties, late fees, negative tax records, and even criminal charges. However, by comprehending the discrepancies between book and tax accounting, companies can manage their taxes proficiently and proficiently, sidestepping unwarranted losses or legal ramifications.

There are two main types of book-tax differences, which are temporary differences and permanent differences. Temporary differences occur when a transaction is recorded for the same amount under both CAS and tax laws but in different time periods. These differences can lead to additional taxable income adjustments in the CIT return, and the recognition of Deferred Tax Assets (DTA) or Deferred Tax Liability (DTL) must be shown in the financial statement.

When a transaction is accounted for differently or with a varying amount under CAS and tax laws, it results in permanent differences. Unlike temporary differences, permanent differences do not create Deferred Tax Assets (DTAs) or Deferred Tax Liabilities (DTLs). However, they impact the amount of Corporate Income Tax (CIT) payable.

Differences in assets, liabilities, income, and expenses can cause both temporary and permanent book-tax differences. For example, for fixed assets, the tax law generally recognizes the tax basis of assets more strictly than the accounting cost to protect taxes. This can result in the initial tax basis of the asset being less than the initial accounting cost because tax recognition means that subsequent costs are eligible for a pre-tax deduction.

Corporate restructurings such as mergers may give rise to temporary differences. Group restructurings can be eligible for a special tax deferral treatment under certain conditions prescribed by tax laws. If allowed, the merged enterprise will determine the tax basis of its assets and liabilities based on the original tax basis of the merged enterprises.

There are also differences between accounting and tax laws in the subsequent measurement of assets. For example, the depreciation method of fixed assets under tax laws is mainly the straight-line method, whereas accounting standards are more flexible and allow both straight-line and accelerated depreciation methods.

Enterprises must understand and distinguish between temporary and permanent differences under CAS and tax laws to adjust their “accounting profits” accurately in the financial statements to their “taxable income” in the tax return. The best way to identify book-tax differences, which are temporary, is by comparing the book basis and tax basis of an item. Companies typically prepare CAS-compliant balance sheets and compare them with tax basis worksheets to identify differences in fixed assets, intangibles, R&D expenditures, and business combinations.

There are some items that may have a book basis but lack a tax basis, such as bad debt provisions that cannot be deducted until they are incurred. On the other hand, there are items that may have a tax basis but no book basis, such as fixed assets that fall below the capitalization threshold for accounting but can still be capitalized under tax laws.

In contrast, identifying permanent differences can be more complicated as they arise from different approaches to calculating gains, expenses, or losses between accounting and tax laws. These differences are not tied to any particular asset or liability in financial reporting, requiring enterprises to meticulously review each profit and loss item to determine whether any timing differences, deduction limits, tax exemptions, or super deductions exist. If the business transactions are complex, it is advisable to seek the assistance of a qualified tax accountant to prepare or review your tax return, such as ourselves.
