Lately, many cross-border sellers have been asking one question:

“If the platform’s turnover is 10 million but only 8 million is reported on the tax return, could that pose a risk?”

“Is it normal for sales figures and financial revenue in the Amazon backend not to match?”

“How much of a discrepancy is needed to trigger a tax alert?”

Whenever I hear these questions, I always start by asking: When you say “platform turnover,” which figure are you referring to? Is it the order amount? Or the actual amount received? Is it revenue including tax? Or net revenue after deducting refunds?

Many sellers believe that as long as the discrepancy between the platform’s transaction volume and the income reported for tax purposes isn’t too large, there’s no problem. But in reality, the tax authorities have never focused simply on numerical discrepancies. Rather, they focus on whether these discrepancies can be plausibly explained.

Today, drawing on real-world business scenarios faced by cross-border sellers, we’ll discuss the relationship between platform turnover and taxable income.

In recent months, many cross-border sellers have encountered the same situation: suddenly receiving tax reminder text messages on their cell phones; getting phone calls from the relevant tax authorities; being notified to verify their business data; and being asked to provide additional documentation.

Many business owners' first reaction is:

“Did they come to investigate?”

“Is there a problem with the company?”

“Do I have to pay back taxes right away?”

In fact, in most cases, receiving a tax text message does not mean that a company is under audit.

But one thing is certain: your business operations data has already been flagged by the tax system’s risk identification system.

In the past, many sellers believed that tax management relied primarily on manual checks. However, today, as platform data, payment data, and tax filing data are gradually integrated, the identification of tax risks increasingly relies on big data models.
