IMMEX Checklist for CFOs: Questions Before Relying on Temporary Import Benefits
The IMMEX benefit is easy to see on a P&L: lower landed cost, deferred taxes, better margins on export work. The exposure is harder to see, because it does not live in the income statement. It lives in aged temporary-import balances, in VAT/IEPS credit positions, and in whether anyone can reconcile them on demand.
This is a CFO-level checklist. You do not need to run the customs process. You need to know whether the benefit you are counting on rests on records that hold.
Reframe the benefit as a position you have to defend
A useful mental shift: the deferred taxes are not saved money, they are a position. As long as imports tie to exports and the records prove it, the position holds. When they do not, the position can reverse — and it reverses as a cash and exposure problem, not a footnote.
So the CFO question is not “how much did IMMEX save us.” It is “if someone asked us to prove the position today, could we, and how fast.”
The questions to put to your team
| Question | What a confident answer sounds like | What a worrying answer sounds like |
|---|---|---|
| Can we produce an aged report of open temporary imports? | ”Yes, here it is, by lot and value" | "We’d have to build it” |
| Do Anexo 24 and the VAT/IEPS control reconcile? | ”We reconcile them on a schedule" | "Different people own those” |
| Who owns import-to-export reconciliation? | A name and a cadence | Silence, or “the broker” |
| Can we trace one export end to end quickly? | ”Give us an hour" | "That could take a while” |
| What is our oldest unexplained open balance? | A known, bounded number | ”We’re not sure” |
You are not auditing the detail. You are testing whether the function exists and has an owner.
A composite picture
Composite scenario: This example combines recurring data-reconciliation patterns seen in cross-border manufacturing workflows. It is not a statement about any specific company.
The monthly savings look great in the board deck. Then the CFO asks for one report: temporary imports older than the normal production cycle, with the export evidence next to them. The team can produce parts of it — some exports, some balances — but not the joined-up view. Nobody did anything wrong. The reconciliation function simply was never assigned. The benefit was real; the ability to defend it was assumed.
What to check first
- Is there an owner, by name, for reconciling imports to exports?
- Can finance see an aged open-balance report without a special project?
- Are Anexo 24 and the VAT/IEPS credit control ever reconciled together?
Questions for your tax advisor and specialist
- What VAT/IEPS exposure could aged or unexplained balances represent for us?
- What reconciliation cadence is appropriate for our volume?
- What evidence should we keep to support the position if it is reviewed?
These belong with a qualified tax advisor and IMMEX specialist who can see your numbers.
Before you escalate
If the team cannot produce an aged open-balance report, or cannot name the reconciliation owner, treat that as a finding worth acting on now rather than at year-end. Commission a focused reconstruction of the largest open balances and bring a tax advisor a sorted picture, not a fire drill.
