What companies should decide before moving into Mexico
Most of the cost and delay in a Mexico expansion traces back to decisions that were made, or left open, before the project began. Before committing capital, it helps to work through a set of foundational questions.
Operating model
Will you form a Mexican subsidiary, operate through a branch, acquire an existing operation, enter a joint venture, or contract with a shelter operator or third-party manufacturer?
Ownership and governance
Who owns the Mexican operation, how are decisions made, and how do those rights connect back to the US parent?
Management authority
Who can sign, bind the company, and act locally for tax, banking, labor, and customs matters?
Funding structure
How will the operation be capitalized, through equity, intercompany loans, or a combination, and how does that interact with Mexican and US tax?
Hiring and workforce plan
Who will be employed directly, what roles will be filled locally, and how do Mexican labor rules apply?
Commercial contracting model
How will the Mexican entity contract with US affiliates and customers, and how do existing commercial terms need to change?
These decisions are connected. Working through them together, early, tends to produce a cleaner and more predictable launch.
Legal workstreams that affect timing and cost
A nearshoring project typically moves through several parallel and sequential legal workstreams, some governed by US law and some by Mexican law. Understanding them in advance helps a company plan realistically.
- Entity formation and foreign investment registration. Incorporation, bylaws, and registration with the National Registry of Foreign Investments, coordinated with Mexican counsel.
- Governance and authority. Board or manager structure, reserved matters, and powers of attorney for local action.
- Labor, employment, and immigration. Employment documentation, social security and payroll setup, workforce composition rules, and permissions for foreign personnel.
- Tax, accounting, transfer pricing, and intercompany arrangements. Mexican tax registration, classification, and arm's-length pricing for transactions with affiliates.
- Customs, trade, IMMEX, and import/export coordination. Customs registration, trade-program eligibility, and import and export flows.
- Real estate, leases, construction, and permits. Facility structure, zoning, utilities, and operational requirements.
- Supply, manufacturing, services, and customer contracts. Commercial agreements adapted for the Mexican entity.
- Banking, powers of attorney, and local execution. Account opening and the documentation needed to act locally.
- Insurance, compliance, and operational launch. Coverage, ongoing obligations, and go-live sequencing.
Entity, governance, and ownership structure
Structure decided up front is far easier than structure corrected later. The right approach depends on the facts, but the main considerations include form of operation, parent liability, decision rights, board or manager structure, reserved matters, powers of attorney, and intercompany agreements.
Common forms include the S.A. de C.V. and the S. de R.L. de C.V., each with different ownership and transfer characteristics. Other paths include a branch, a joint venture, an acquisition of an existing operation, a shelter arrangement, or contract manufacturing.
Entity choice in Mexico can also affect how the operation is treated for US tax purposes, which is one reason this decision is best coordinated across both jurisdictions rather than made in isolation.
Labor, immigration, and workforce planning
Mexican labor law differs meaningfully from US practice, and workforce planning should begin early. Key areas include local employer obligations, written employment documentation, social security and payroll coordination, workforce composition rules, foreign managers or technical personnel, and immigration permissions where needed.
Mexican labor law generally requires that at least 90 percent of a company's workforce be Mexican. Directors, administrators, and general managers are generally treated differently under this rule. How it applies to a particular operation depends on the facts.
The specifics are fact-driven. The applicable rules, and how they affect a given staffing plan, should be reviewed with counsel for the particular situation.
Real estate, contracts, permits, and operational launch
A facility decision touches legal, regulatory, and commercial questions at once. Many manufacturers lease space in established industrial parks, which can shorten timelines and shift some site responsibilities; purchase suits longer-horizon operations and involves deeper diligence.
Existing commercial relationships often need to be reviewed and adapted when a Mexican entity becomes the contracting party. Pricing, Incoterms, payment, and responsibility allocations can shift when the Mexican entity is contracting rather than the US parent.
Launch sequencing also matters: facility readiness, permits, hiring, and import capability need to line up so the operation can begin as planned.
Customs, IMMEX, tax, and advisor coordination
Nearshoring usually requires more than corporate formation. If goods are crossing the border, customs and tax structure are central to the project, not afterthoughts.
Where applicable, the IMMEX program can defer import duties on temporarily imported inputs. Eliminating the value-added tax cash outlay on those imports generally requires a separate certification, and both depend on the specific facts of the operation.
A Mexican operation can have significant US tax consequences for the parent, which is why US tax analysis belongs at the front of the project. HIRO Law works as cross-border coordinating counsel, helping align legal, tax, customs, and accounting workstreams with the full picture in view.
Why cross-border coordination matters
US and Mexican workstreams do not operate in separate lanes. Decisions made by the US parent affect how the project is executed in Mexico. Choices about the Mexican entity affect US tax treatment and reporting. Contracts, financing, collateral, employment, customs, and tax cannot be handled in isolated silos, because a decision in one area frequently changes the right answer in another.
Coordination does not remove risk or guarantee an outcome. It does help a company see how the pieces fit together before commitments are made.
Nearshoring legal readiness FAQs
When should legal planning start for a Mexico expansion?
Generally as early as possible, ideally before the operating model, facility, and tax structure are committed. Several decisions, such as entity selection and tax classification, are easier to make well at the outset than to change later. The right timing depends on the specific plans.
Does a US company need a Mexican entity to operate in Mexico?
Not always. Some companies operate through contract manufacturing or shelter arrangements rather than forming their own entity. Whether an entity is needed depends on the activities involved, tax and permanent-establishment considerations, and how goods, workers, and contracts are arranged. This should be analyzed for the particular situation.
Should a US company use a branch, subsidiary, shelter, or joint venture?
It depends on the facts, including liability tolerance, tax position, control needs, speed to market, and whether an existing operation is involved. Each structure has different implications for liability, governance, and US and Mexican tax. The choice is best made with counsel and tax advisors after reviewing the specific objectives.
What is the 90% Mexican workforce rule?
Mexican labor law generally requires that at least 90 percent of a company's workforce be Mexican, with different treatment for directors, administrators, and general managers, and limited allowances for specialized foreign personnel. How the rule applies to a given operation depends on the facts and should be reviewed with counsel.
Does nearshoring require IMMEX certification?
Not in every case. IMMEX is a trade program that can provide duty deferral for qualifying manufacturers that import inputs and export goods, but it is not required for every operation, and its benefits and obligations depend on the specifics. Whether IMMEX or another program fits a particular operation is a fact-specific question.
What contracts should be reviewed before launch?
Commonly, supply and manufacturing agreements, customer contracts, intercompany agreements between the Mexican entity and US affiliates, leases, and service contracts. When the Mexican entity becomes the contracting party, commercial terms often need to be adjusted. The right scope of review depends on the operation.
Who should coordinate legal, tax, customs, and accounting workstreams?
These workstreams are interdependent, so coordination matters. HIRO Law can act as cross-border coordinating counsel, working alongside tax advisors, accountants, customs brokers, and local counsel so that decisions in one area account for their effects in the others.
