Bank of China avoided $348m in taxes using fund structures, auditors accuse

Bank of China evaded 2.37 billion yuan, or US$348 million, in taxes by misusing preferential treatment meant for publicly offered mutual funds, according to an annual report from China’s National Audit Office. The auditor says the scheme was carried out between April 2023 and August 2025, a two-year window that matters because it overlaps with a period when Beijing has been turning the compliance dial up on financial institutions.

The key allegation is not just that the bank paid the wrong amount, but that it exploited investment fund structures. In other words: the tax break was designed for a certain kind of publicly offered mutual fund, and the bank allegedly used a disguised structure to capture the benefit without fitting the policy intent. That is the kind of mismatch regulators hate, because it turns targeted incentives into a loophole.

To understand why this became an audit headline, you have to look at how mutual-fund tax preferences typically work in financial systems like China’s. Governments often give preferential tax treatment to widely offered investment products to encourage broader public participation and channel savings into capital markets. Those preferences usually come with conditions tied to what counts as “publicly offered,” plus rules around how the product is structured and sold. The National Audit Office’s accusation, as described in the report, is essentially that Bank of China bent those conditions by using investment fund structures that were not aligned with the intent of the preferential policy.

This is also a governance story, not just an accounting story. For a major state-owned bank like Bank of China, decisions that touch taxes and investment structures typically involve multiple layers: treasury and product teams design or choose vehicles, compliance functions assess regulatory risk, and finance teams execute tax positions and reporting. An audit result like this usually raises uncomfortable questions for boards and executives: How did the bank’s internal controls miss the risk? Were the “preferential” structures approved as compliant because they met the letter of some rules, while still violating the spirit? And once the first use occurred, what stopped the behavior from continuing year after year through August 2025?

Beijing’s enforcement posture provides context. The audit report is framed as part of steps “to strengthen financial compliance.” That matters because compliance tightening tends to be most painful for large institutions with complex transactions. When regulators move from guidance to scrutiny, the backlog of “technically possible” structures becomes a liability. Even if a bank’s interpretation survived in day-to-day operations, an audit can still conclude that the interpretation should not have benefited from preferential treatment intended for publicly offered mutual funds.

For decision-makers across the banking sector, the second-order effect is clear: audits do not just identify losses, they reshape risk models and internal governance priorities. An allegation that a bank evaded 2.37 billion yuan in taxes by misusing preferential treatment suggests that similar fund structures across the industry could be reviewed more aggressively. That means more documentation, tighter approval workflows for product and tax treatments, and potentially a reclassification of certain investment vehicles from “standard” to “high scrutiny.”

There is also an investor and market implication, even if this story is primarily regulatory. When financial compliance enforcement intensifies, it can affect how capital is allocated inside banks. Compliance costs, remediation costs, and the need to adjust structures can all divert resources that might otherwise go to growth. For boards, this increases the pressure to treat compliance as an enterprise-wide system rather than a checklist for the back office. The audit’s timing, running from April 2023 to August 2025, suggests the alleged conduct persisted through multiple reporting cycles, which can magnify reputational risk and internal accountability questions.

Ultimately, this case is a reminder that tax incentives are policy tools, not free-form engineering problems. If the preferential treatment is designed for publicly offered mutual funds, then using disguised structures to capture the benefit without meeting the intent can trigger enforcement. For executives at peer banks, the strategic stake is simple: reduce the chance that your most “clever” structures become next year’s audit finding. In a compliance tightening cycle, the cost of treating tax and fund architecture as purely technical can be far more expensive than any short-term advantage.
