2026 Compliance Calendar: China Bookkeeping & Tax Deadlines for Foreign Companies

Every foreign company operating in China carries a long list of recurring filing obligations — monthly, quarterly, and annual. Missing a single deadline can trigger late-filing penalties, block your ability to issue invoices, and flag your company for a tax audit. This compliance calendar maps the standard bookkeeping and tax deadlines that foreign-invested companies in Guangzhou, Shenzhen, Foshan, and Dongguan must meet each year, so you can plan ahead instead of scrambling at the last minute.

Why China’s filing calendar catches foreign companies off guard

Unlike many Western jurisdictions where a single annual return covers most obligations, China runs on a continuous cycle of declarations. Your company reports value-added tax (VAT) and withholds individual income tax (IIT) every month, prepays corporate income tax (CIT) every quarter, and reconciles everything annually. The deadlines are fixed and non-negotiable, and the tax authorities know exactly when you are late.

For a newly incorporated foreign company, the first surprise is usually the fapiao system. Every VAT invoice you issue must be declared through China’s official tax invoice (fapiao) system, and those declarations feed directly into your monthly VAT return. If your records are not current, you cannot issue invoices — which in practice means you cannot bill clients. That single dependency is why disciplined bookkeeping for a foreign company in China matters far more than most overseas founders expect.

Monthly compliance tasks

Most foreign-invested companies are general VAT taxpayers and file monthly. Your recurring monthly obligations typically include:

• VAT and surcharges: filed and paid by the 15th of the following month. The return must reconcile with every fapiao issued and received during the period.
• IIT withholding for employees: wages are subject to monthly withholding, declared and paid by the 15th of the following month. This applies whether your staff are Chinese nationals or foreign employees — and IIT for foreign employees carries its own residency and sourcing rules.
• Social insurance and housing fund: contributions are generally declared and paid monthly, with city-specific cut-off dates. In Guangzhou, Shenzhen, Foshan, and Dongguan the local contribution bases differ, so the amounts you remit depend on where each employee is registered.

Because VAT, IIT, and social insurance all hit around the same mid-month window, a reliable China payroll and compliance process is essential to avoid piling three deadlines into one rushed week.

Quarterly compliance tasks

Corporate income tax in China is prepaid on a quarterly basis. After each quarter ends, you must file a CIT prepayment return and remit tax on your estimated taxable profit within 15 days. Alongside the CIT prepayment, most companies submit quarterly financial statements to the tax authorities.

Quarterly reporting is also the moment when bookkeeping quality is tested. Because prepayments are based on your accounting records, sloppy monthly entries surface here as either underpaid tax or an inflated liability. Since China’s Golden Tax System now cross-checks your invoices, your declarations, and your bank data in near real time, discrepancies between your books and your filings are flagged faster than ever.

Annual compliance tasks

The annual cycle is where most of the heavy lifting — and most of the risk — sits:

• Annual CIT reconciliation (huisu qingsuan): due by 31 May of the following year. This is the full-year tax return that settles the difference between your quarterly prepayments and your final tax liability. It requires a complete set of reconciled financial statements.
• Annual report to the market regulator: every company must file its annual report with the State Administration for Market Regulation between 1 January and 30 June. Late filing can place your company on the abnormal-operations list, which damages credit and can block routine approvals.
• Annual audit: while not mandatory for every company, many foreign-invested enterprises, representative offices, and firms in regulated sectors must have their accounts audited by a qualified Chinese CPA firm. Preparing for the China annual audit is dramatically easier when your monthly and quarterly filings have been clean all year.
• IIT annual reconciliation for employees: individuals settle their comprehensive income tax between 1 March and 30 June. Employers are expected to support staff through this process, particularly foreign employees with cross-border income.

Record-keeping rules you must follow

China’s bookkeeping rules are prescriptive. Your accounts must follow Chinese Accounting Standards (the ASBEs), be maintained in renminbi, and be supported by original documents that are in Chinese or accompanied by Chinese translations. Accounting records and supporting vouchers must generally be retained for a set period — commonly 10 years or longer for certain archives — and your accounting software must meet regulatory requirements. Failure to keep proper records is itself a compliance violation, and it makes any subsequent tax audit far more painful to survive.

How deadlines work in Guangzhou, Shenzhen, Foshan and Dongguan

The core deadlines above are national, so a company in Guangzhou faces the same VAT and CIT dates as one in Shenzhen, Foshan, or Dongguan. What varies by city is the detail: social insurance and housing fund contribution bases, the exact cut-off dates for monthly remittance, and the local tax bureau’s preferred declaration channels. For example, social insurance contribution floors and ceilings in Shenzhen can differ meaningfully from those in Foshan or Dongguan, which directly changes your monthly payroll cost. This is why a local bookkeeping and tax service provider that already operates across the Pearl River Delta’s core cities can keep every entity compliant without guesswork.

Penalties for missed filings — and how to avoid them

Late VAT, CIT, or IIT filings generally attract a daily surcharge on the unpaid tax, and persistent failures can lead to formal penalties, downgraded tax credit ratings, and restrictions on invoice issuance. A company that cannot issue fapiao cannot get paid on normal terms — a cash-flow problem that compounds quickly. The single most effective safeguard is a fixed monthly close process: book records, reconcile fapiao, file declarations, and remit tax in a disciplined sequence every single month.
