The essentials

At a glance

  • A pre-operational VAT review is tied to the planned activities and applicable conditions.
  • Project evidence needs to connect expenditure with the intended business.
  • The transition into operations is part of the planning, not the end of it.

Understand the pre-operational VAT question

Mexico’s VAT Law addresses expenses and investments incurred before the start of the relevant business activities. Article 5 provides a framework for the treatment of qualifying pre-operational VAT, including a refund route under specified conditions. The project’s intended taxable or zero-rated activities matter to that assessment.

This is a review of the company’s VAT position, not an automatic reimbursement of every startup cost. The appropriate treatment depends on the facts, the applicable requirements, and the option adopted with the company’s tax advisers.

Tell a consistent investment story

The investment plan, accounting records, contracts, and implementation timetable should describe the same project. SAT’s business-refund guidance calls for supporting information about the investment and its intended activities in a pre-operational application.

Use that as the basis for a clear internal project file. It should explain what the company is building, why the expenditure belongs to that plan, and how the supporting records can be traced without relying on the memory of one person.

  • Maintain an approved project narrative and investment schedule.
  • Link purchase records, payments, and accounting entries.
  • Organize contracts, facility information, and relevant project approvals.
  • Keep evidence of funding and explain material changes to the plan.

Create a review process before filing

A useful working file separates confirmed evidence from items still being resolved. Give the finance team and tax advisers a common register of invoices, payment support, accounting references, and open questions. That makes a targeted review possible before the claim is prepared.

Avoid letting the refund file become a disconnected spreadsheet. Agree on who approves changes, where the source documents are stored, and how the figures reconcile with the company’s records. These are practical project controls, rather than a complete statement of statutory requirements.

Prepare for the move into operations

The VAT Law also addresses the subsequent review of the proportion used during the pre-operational period and circumstances affecting amounts already refunded. A change in the project or the start of operations therefore belongs in the follow-up plan, rather than being treated as an unrelated event.

Keep the initial assumptions accessible to the team that takes over ongoing tax compliance. Record the actual start of activities and bring changes in the investment or business model to the tax advisers’ attention.

Assess ISR separately from investment VAT

A startup investment should not be treated as proof of an income-tax refund. An ISR review starts from the company’s own income-tax calculation, filings, and any supportable credit balance. Organize that discussion separately so that a potential VAT application does not create an unsupported expectation about ISR.
