Mexico–U.S. cross-border accounting and tax
When an operation lives in both countries, every intercompany payment, every partner and every contract has consequences on both sides. We handle accounting and compliance in Mexico and the U.S. side with the same team, so the numbers reconcile in both jurisdictions.
Where it gets complicated
Two sets of books that don't match
The Mexican subsidiary reports under Mexican GAAP (NIF) in pesos; the parent consolidates under U.S. GAAP in dollars. If nobody reconciles, the differences surface in the audit.
Payments to foreign accounts
Mexican vendors asking to be paid into U.S. accounts, parent-company services, expense reimbursements: each case has different deductibility, withholding and invoicing rules.
U.S. partners in a Mexican operation
A U.S. LLC or partnership with activity in Mexico carries IRS obligations: Form 1065, K-1s, K-3s and foreign entity reporting.
Trapped VAT
During exploration and development, Mexican VAT credits grow every month and tie up working capital. See VAT refunds.

Frequently asked questions
Do you prepare U.S. returns?
Yes. We prepare federal returns, including partnership returns (Form 1065) and partner K-1s, as IRS-registered preparers.
What if a Mexican vendor asks to be paid into a U.S. account?
It can be done, but the payment's deductibility, the supporting CFDI invoice and any withholding need to be reviewed. That review should happen before the first payment, not after.
Can you take only Mexico or only the U.S.?
Yes. The value is in seeing both sides, but we can take one jurisdiction and coordinate in writing with whoever handles the other.
Do you work with our external auditor?
Yes. We prepare the information and reconciliations the auditor requests and address their findings.
