Many sellers on Meikeduo, once their monthly sales reach a certain level, suddenly find that their profits are significantly lower than expected. When they check their backend data, the numbers in the tax deduction column are heartbreaking.

It’s not that the platform is deducting fees arbitrarily; it’s that you don’t realize just how big the tax difference is depending on whether or not you link your RFC tax ID.

01 Let’s start by looking at a set of numbers

Meikeduo Cross-Border StoreDoes not have its own RFC tax IDIn such cases, the maximum comprehensive tax rate withheld and remitted by the platform can reach36%: 16% VAT + 20% income tax are deducted directly from your payment, with no room for offsetting.

Once you have obtained your own RFC tax number and are operating in compliance, you can claim input tax credits, and after the 2026 tax reform, the optimal tax rate bracket could be reduced to10.5%or so.

You can't make up for that difference just by selling a few more items.

02 Tax Differences Based on Monthly Revenue: We'll Show You the Calculations

This table shows that if monthly revenue is 1 million, the business will have to pay an additional 255,000 in taxes each month because it hasn’t registered for a tax ID, which amounts to 3.06 million per year.This isn't something that can be achieved through operational optimization; it's determined by the compliance framework.

03 Why Is There Such a Big Gap?

Two reasons:

1. VAT Credit: Sellers with an RFC tax ID can claim input VAT credits for procurement, logistics, warehousing, and other expenses incurred within Mexico. For those without a tax ID, the platform will withhold the full amount on their behalf, and they will not be able to claim these credits.
2. Income Tax Basis: Sellers with a tax ID file income tax returns based on net profit, and their costs and expenses are tax-deductible; for those without a tax ID, the platform assesses and collects taxes based on transaction volume, leaving no room for cost deductions.

To put it simply:If you don't have a tax ID number, you pay taxes based on your “revenue”; if you do have a tax ID number, you pay taxes based on your “profit.”

04 Linking a tax ID isn't a cost—it's a way to cut losses

Many sellers worry about “how much it costs to link a tax ID,” but they overlook a much larger figure—If you don't link your tax ID, the platform will withhold the money for you.

If your monthly revenue has stabilized at over 100,000, the hidden costs of not linking your tax ID have most likely already exceeded the one-time investment required to link it.

It’s not a question of “whether to tie it or not,” but rather “when to tie it”—The sooner you sign up, the more you'll save.
