01 What is CRS? What does it have to do with your Hong Kong company?

CRS, or Common Reporting Standard, is an OECD-driven initiative that has been developed by the United States Department of Energy (DOE) and the United States Department of State.Automatic global tax information exchange mechanismThe

Simply put:The financial institutions in the contracting country/region will automatically report the account information of a non-local tax resident to the resident's country of tax residence.

Hong Kong joined the CRS in 2018 and has initiated the exchange of information with more than 100 tax jurisdictions, including Mainland China.

What does that mean?

Your situation.Does CRS exchange?
You are a Mainland tax resident holding a Hong Kong company account✅ Exchange
You are a Mainland tax resident holding a Hong Kong personal bank account✅ Exchange
Your Hong Kong company is under the de facto control of a Mainland resident✅ Possible exchange (penetration review)
You're a Hong Kong tax resident and your account is in Hong Kong.❌ Does not involve cross-district exchanges

Key Conclusion: As long as you are a tax resident of Mainland China, your financial account information in Hong Kong will be automatically reported to the State Administration of Taxation of China every year.

02 What information is being exchanged?

The account information exchanged by CRS is very specific and includes, but is not limited to:

Type of informationconcrete content
Account Holder InformationName, address, tax resident status, taxpayer identification number
Basic Account InformationAccount number, account type (deposit/custodial/investment, etc.)
account balanceBalance or net value of accounts at end of year
Trading InformationAnnual interest, dividends, insurance income, etc.
where the money is flowingRecording of large incoming and outgoing transactions

How much money you have in your Hong Kong account, where it comes from and where it goes - all this information, the mainland tax authorities receive a copy every year.

03 Which sellers are most likely to be “targeted”?

The CRS information exchange itself doesn't mean you have a problem, but it gives the IRS a data base to cross-reference.

Here are a few things that are most likely to go wrong when cross-referenced:

Scenario 1: Hong Kong company has income but never declared in the Mainland

Your Hong Kong account has a large amount of platform returns coming in every year, and CRS reports this data to the mainland tax authorities. However, this income is not reflected at all in your personal income tax or enterprise income tax returns in the Mainland.

→ Data mismatch triggers an early warning.

Scenario 2: Hong Kong company's profits remain overseas for a long time and are not repatriated to the Mainland

You have an ODI filing or shareholding structure, it is reasonable to say that the profits of the Hong Kong company should be remitted back to the mainland to declare tax. But the profits have been “lying” in the Hong Kong account.

→ The IRS will question: was there an intent to delay payment of taxes?

Scenario 3: Personal account receipts from company operations

Some sellers, for the sake of convenience, platform back to Hong Kong personal account. CRS on personal account also exchange information, and personal account of large amount of incoming money is more likely to be noticed.

→ Compliance risks are greatest when public and private are not separated.

📞 If you fall into any of the above categories, it is advisable to sort it out as soon as possible. Contact us - a team of professionals to help you identify risks and develop a compliance and rectification program.

04 Having a Hong Kong company does not mean having problems, the key is “compliance or non-compliance”.”

CRS is not a flood, it just makes information transparent.

Compliant sellers, no worries at all. Because your income has been declared under the correct subject, the money link is clear, and the data exchanged by the CRS is the same as the data you report to the IRS.

However, if your situation falls into any of the following categories, it is advisable to freshen up as soon as possible:

status quorisk levelSuggested Action
Hong Kong company has income that has never been declared in the Mainland🔴 HighSort out tax returns as soon as possible to fill in the gaps
Mixed use of public and private accounts🔴 HighSeparation of corporate and personal accounts
Keeping profits in Hong Kong for a long time without repatriation🟡 MediumEvaluate the need for repatriation or process through a compliance route
There is an ODI filing but there is a mismatch in the flow of funds🟡 MediumRe-check funding links to ensure consistency
Clear structure and normal declaration on both sides🟢 LowMaintain status quo, regular self-examination

05 Compliance isn't about tax evasion, it's about putting together a sensible tax planning pathway

Many sellers panic when they hear about CRS, thinking, “Are we going to transfer all the money back and pay all the taxes?”.

It's not.

Compliant tax planning is perfectly legal. For example:

  • pass (a bill or inspection etc)Hong Kong Company + Mainland Company Dual Body StructureRational Distribution of Profits
  • Eligible Hong Kong CompaniesApplying for an offshore exemption, legally reducing the tax burden on overseas profits
  • pass (a bill or inspection etc)ODI FilingRepatriation of overseas profits in a compliant manner
  • Every step of the funding chainContracts, vouchers, sound business logic

The key is not to “hide”, but to “clarify”.
