China Annual Reconciliation & CIT Settlement: IIT & Corporate Filings (2025)

Accounting › Country Tax Guides › China Tax

China’s annual reconciliation and CIT settlement are where the year’s tax is finalized for individuals and companies. This guide explains the IIT annual reconciliation, the 2025 Administration Measures that formalized it, the CIT annual settlement process, book-tax differences, and how both individuals and businesses complete these critical year-end filings correctly in China.

What is the IIT annual reconciliation?

Resident individuals with comprehensive income generally must complete the IIT annual reconciliation between March 1 and June 30 of the following year, settling the difference between tax withheld during the year and the actual annual liability. This pulls together all comprehensive income (wages, labor service, author’s remuneration, royalties) and deductions, calculating the final tax and producing a refund or additional payment. Income taxed separately, like rental or property gains, is excluded.

The reconciliation is necessary because monthly withholding may not exactly match the annual tax, especially for those with multiple income sources, mid-year job changes, or varying income. For 2024 income, the reconciliation ran March 1 to June 30, 2025. Completing it correctly ensures individuals pay the right tax and claim refunds owed, and is a key annual compliance obligation for resident taxpayers in China.

What did the 2025 Administration Measures change?

On February 26, 2025, the State Taxation Administration issued the Administration Measures on IIT Reconciliation for Comprehensive Income, formalizing and standardizing the process. The Measures clarify the responsibilities of taxpayers and withholding agents, refine the procedures for filing, deduction claims and refunds, allow taxpayers to apply for filing extensions from 2025, and emphasize the tax credit mechanism with penalties for non-compliance.

The Measures also continue the principle of ‘no penalty for a first-time violation’ — if taxpayers correct under-reported or underpaid amounts, the authorities promptly remove non-compliance remarks from their records. Notably, they introduce a credit-constraint mechanism: if a legal representative or partner fails to complete their IIT reconciliation, it can affect the tax credit rating of their enterprise. This links individual compliance to corporate standing, raising the stakes for executives.

Who is exempt from the IIT reconciliation?

Not every resident must reconcile. The STA exempts individuals where the final tax payable does not exceed RMB 400, where annual comprehensive income is no more than RMB 120,000 in cases of top-up liabilities, or where the tax prepaid already matches the final liability and the withholding agent fulfilled its duties correctly. Those due a refund can choose whether to file to claim it.

These exemptions spare many ordinary employees with single, accurately-withheld salaries from needing to reconcile. But individuals with multiple income sources, unclaimed deductions, or variable income often must reconcile and may owe additional tax or be due a refund. Understanding whether you fall within an exemption, or must reconcile, is the first step for individuals each reconciliation season, ensuring they meet the obligation only when required while claiming refunds they’re owed.

How does the CIT annual settlement work?

The CIT annual settlement, due May 31, is where a company files its annual CIT return, reconciles its four quarterly prepayments against the actual annual tax (based on the year-end audit), and pays any shortfall or claims a refund. It involves adjusting accounting profit for tax purposes — addressing book-tax differences — and applying deductions, incentives and loss carryforwards to determine the final CIT liability for the year.

The settlement is a substantial exercise requiring the audited financial statements, tax adjustments, and supporting documentation. For foreign-invested enterprises, it follows the mandatory annual audit. The STA’s review of the settlement drives downstream clearances, including the certificate needed for dividend remittances. Completing the CIT settlement accurately and on time is the most important annual compliance task for companies, finalizing their corporate tax and enabling profit access.

What are book-tax differences?

Book-tax differences are discrepancies between how a transaction is treated under China’s accounting standards (CAS) and under the tax laws — for the same item, the timing or amount of recognition can differ for accounting versus tax. During the CIT settlement, companies must adjust their accounting profit to arrive at taxable income, accounting for these differences. Managing book-tax differences is a major task in the annual reconciliation.

Common book-tax differences arise from depreciation methods, provisions, revenue recognition timing, and non-deductible expenses. The settlement requires identifying and adjusting for each, which can be complex. Accurate management of book-tax differences ensures the taxable income — and CIT — is calculated correctly. For companies, especially those with complex operations, handling these differences properly is central to a correct CIT settlement, often requiring accounting and tax expertise.

A practical example: completing the settlements

Consider a foreign-invested enterprise: after its year-end audit (by ~April 30), it prepares the CIT settlement, adjusting accounting profit for book-tax differences, applying its incentives and loss carryforwards, reconciling quarterly prepayments, and filing by May 31 — then obtaining the clearance to remit its dividend. Meanwhile, its employees complete their IIT reconciliations between March and June, those with multiple income sources settling additional tax.

The example shows how the two settlements run in parallel each spring, both requiring accurate records and timely filing. The CIT settlement is the company’s critical task, gating profit repatriation; the IIT reconciliation is the individuals’ obligation. Understanding both processes — and preparing for them proactively — is essential for businesses and their employees to finalize the year’s tax correctly and access refunds or profits in China.

How do equity incentives affect the IIT reconciliation?

The 2025 Measures clarified the treatment of equity-based incentives in the IIT reconciliation. If a taxpayer receives multiple lots of equity incentives from different entities in a year, they’re no longer required to have their current employer consolidate the income with that from a previous employer; if from the same entity, the income should be consolidated. This simplifies the handling of equity incentives across employers.

For employees receiving stock options or other equity incentives — common for foreign employees and at multinational and tech companies — this clarification affects how their equity income is reconciled. Equity incentives vesting during the year are a common trigger for meaningful additional tax at reconciliation. Understanding the rules for consolidating equity income across entities helps affected employees complete their reconciliation correctly, particularly those with incentives from multiple sources.

Can taxpayers apply for filing extensions?

Starting from 2025, the IIT Reconciliation Measures allow taxpayers to apply for an extension to file their reconciliation. Taxpayers whose extension applications are approved should still pre-pay their tax before the original filing deadline. This provides flexibility for those who can’t complete the reconciliation within the standard window, while ensuring the tax itself is paid on time.

This extension option is a new accommodation recognizing that some taxpayers face genuine difficulties completing the reconciliation by June 30. The requirement to pre-pay tax means the extension is for the filing, not the payment. For taxpayers with complex situations, the ability to request an extension provides welcome flexibility. Understanding that extensions are available from 2025 — with pre-payment required — helps taxpayers who need additional time manage their reconciliation obligations.

How does the statutory audit relate to the CIT settlement?

For foreign-invested enterprises, the mandatory annual statutory audit (by a China-licensed CPA, typically due around April 30) precedes and feeds the CIT settlement. The audited financial statements provide the verified accounting profit that the CIT settlement adjusts for book-tax differences to reach taxable income. So the audit and settlement are sequential: audit first, then the CIT settlement based on the audited figures.

This sequence means FIEs must complete their audit in time to prepare the CIT settlement by May 31. The audit verifies the financial statements under CAS, and the settlement then makes the tax adjustments. Understanding the relationship — the audit underpinning the settlement — helps FIEs sequence their year-end compliance correctly, ensuring the audit is done in time to support an accurate, timely CIT settlement and the downstream clearances it enables.

What if an individual has income from multiple sources?

Individuals with comprehensive income from multiple sources — multiple employers, or wages plus significant labor service income — often must reconcile, as monthly withholding by each payer may not reflect the correct annual tax on their combined income. Pooling the income at reconciliation can reveal additional tax owed (if combined income pushes into higher brackets) or a refund. These individuals typically can’t use the exemptions.

For such individuals, the reconciliation is essential to settle the correct annual tax on their total comprehensive income. Those with single, accurately-withheld salaries may be exempt, but multiple-source earners usually must reconcile. Understanding that multiple income sources generally trigger a reconciliation obligation — and can result in additional tax — helps affected individuals prepare to complete it correctly and budget for any top-up payment during the March-to-June window.

Common settlement mistakes to avoid

Frequent settlement mistakes include starting too late (causing a rushed, error-prone filing), mishandling book-tax differences (miscalculating taxable income), missing the audit deadline that feeds the CIT settlement, individuals overlooking a required reconciliation, and not claiming refunds owed. Each can lead to incorrect tax, penalties, or stalled clearances.

Avoiding them means preparing proactively after year-end, carefully managing book-tax differences, sequencing the audit before the settlement, determining reconciliation obligations correctly, and claiming refunds. Because the CIT settlement gates dividend remittances and the IIT reconciliation affects credit ratings, accuracy matters. Understanding both settlements — and preparing for them early — helps businesses and individuals avoid these mistakes and finalize their tax correctly and on time.

Why the settlements matter for foreign investors

For foreign investors, the annual settlements are especially consequential because the CIT settlement gates profit repatriation — the STA’s review drives the tax clearance a bank requires to release dividends to the foreign parent. A delayed or problematic settlement can stall the dividend, trapping profits in China. The IIT reconciliation, meanwhile, affects the credit rating through the executive-compliance linkage.

This means foreign investors must treat the settlements as critical priorities, ensuring the audit, CIT settlement and related filings are completed accurately and on time to enable profit access. The connection between the CIT settlement and dividend remittances makes it central to the investment’s financial returns. Understanding why the settlements matter so much for foreign investors — beyond compliance, to profit repatriation — underscores their importance in operating a China investment.
