Variable Capital Corporation (S.A. de C.V.): Advantages and How to Form One

Choosing the right corporate structure is one of the most important decisions when forming a business in Mexico. An incorrect choice can be fiscally costly and limit future business growth.

What is an S.A. de C.V. (Variable Capital Corporation)?

The Variable Capital Corporation (S.A. de C.V.) is the most widely used corporate structure in Mexico for medium and large businesses. Its main features are limited liability of shareholders (they are only liable up to their capital contribution) and the ability to modify the share capital without needing to amend the articles of incorporation each time.

Advantages over other structures

Compared to the Limited Liability Company (S. de R.L.) and the individual with business activity, the S.A. de C.V. offers:

When is the S.A. de C.V. NOT the right choice?

For small businesses with a single owner billing less than $3.5M annually, the S.A. de C.V. may impose excessive tax and corporate governance obligations. In those cases, the RESICO regime or individual business activity regime may be more efficient.

The formation process

Forming an S.A. de C.V. in Mexico requires: drafting the articles of incorporation before a notary public, obtaining the RFC and e.firma from the SAT, opening a business bank account, registering with the IMSS if employees will be hired, and registering in the state taxpayer registry. The complete process takes between 3 and 6 weeks.

Representative case

How we work: before and after

Situation based on real cases handled by the firm. Data modified to protect client confidentiality.

Before

Business owner operating as an individual with high personal asset risk

A consulting services provider in SLP was operating as an individual with corporate clients requiring contracts of $500K or more. A lawsuit from a dissatisfied client threatened his personal assets, including his home and vehicle.

After

Company formed and personal assets protected

We formed the S.A. de C.V. in four weeks, transferred the active contracts to the new legal entity, and designed the most tax-efficient compensation structure for the director. During the dispute with the client, the asset separation was decisive: the lawsuit was limited to the company's capital and personal assets remained untouched.
