VAT refunds are one of the most important tax procedures for exporting companies, manufacturers, and businesses that make ongoing investments. However, recovering a tax credit from the SAT (Mexican Tax Administration Service) depends on more than simply submitting the application; it requires a thorough analysis of operations, documentation, and cash flow.

A few months ago, TAX ID welcomed a client who manufactures locks. The company produces its products in Mexico and exports them to the United States, generating VAT credits from the purchase of imported raw materials, local expenses, and services essential to its operations.

Based on our experience, we have found that a large part of the success in obtaining an effective VAT refund lies in understanding why the credit balances are generated and having solid records that allow each transaction to be proven.

Why are VAT credit balances generated?

VAT credits typically arise when a company pays more VAT than it charges its customers. This frequently occurs in sectors such as:

  • Manufacturing companies.
  • Exporting companies.
  • Maquiladora industry.
  • Companies with heavy investments in machinery and equipment.
  • Businesses with long production cycles.
  • Companies that carry out operations taxed at a rate of 0 %.

In the case of exports, Mexican legislation establishes a rate of 0.%, while the company continues to pay VAT on its inputs, services and operating expenses.

Our methodology for requesting a VAT refund

At TAX ID we have adopted the policy of reviewing 100% of the transactions before submitting a refund request to the SAT.

1. Comprehensive review of bank deposits

We analyze all deposits received to confirm their origin and supporting documentation:

  • We verify that the income is properly invoiced.
  • We review capital contributions and ensure they are properly documented.
  • We analyze loans and financing to confirm the existence of contracts with a certain date.
  • We validate the payment and documentation of interest.
  • We identify unusual operations that may generate observations from the authority.

2. Validation of creditable VAT

The tax authorities typically focus a large part of their audits on creditable VAT. Therefore:

  • We reconciled 100% of the cash flow against the bank statements.
  • We verify that the expenses are strictly necessary.
  • We review CFDI and payment supplements.
  • We validate contracts, purchase orders, and documentation from strategic suppliers.
  • We confirm the correct accounting and tax determination of each transaction.

3. Documentary review and materiality of the operations

A successful refund requires proof that the transactions actually occurred.

Depending on the type of business, we review:

  • Contracts.
  • Customs declarations and documentation.
  • Evidence of delivery.
  • Account statements.
  • Working papers.
  • Accounting records.
  • Corporate files.

Our goal is to guarantee the complete traceability of every accredited weight.

The real differentiator: understanding the customer's business

One of the main mistakes when requesting a VAT refund is to only analyze the numbers.

In our experience, the real differentiator lies in understanding the client's infrastructure, their production processes, their supply chain, and how they operate daily. No two returns are the same.

Understanding how revenue is generated, how money flows, and what the internal processes are allows you to anticipate observations from the SAT (Mexican Tax Administration Service) and strengthen the file from the beginning.

What does the SAT check in a VAT refund?

Before authorizing a refund, the authority usually asks questions such as:

  • Why is a credit balance generated?
  • What is the origin of the resources?
  • How were the goods and services paid for?
  • Are the transactions real and verifiable?
  • Are expenses essential for economic activity?
  • Is there consistency between the accounting, banking, and tax returns?

Answering these questions correctly can make the difference between getting a refund or facing additional requirements.

Conclusion

Obtaining a VAT refund from the SAT (Mexican Tax Administration Service) is not simply a matter of submitting an electronic request. Success depends on understanding the origin of the credit balance, reviewing cash flow, and having all the necessary documentation.

At TAX ID we believe that a successful refund begins long before submitting the application: it starts with a deep understanding of the business, a thorough review of the information, and ongoing support for the client.

If your company generates recurring VAT credits, a preventative review can help reduce risks and improve the chances of recovering your tax in less time.
