Most foreign investors entering Colombia choose between two structures: the SAS (Sociedad por Acciones Simplificada), a fully independent Colombian legal entity, or a Branch Office (Sucursal), a direct extension of your existing foreign company. The core difference is legal personality: an SAS creates a new, separate entity with its own liability shield, while a branch office has no legal identity apart from its parent company, which means the parent remains directly liable for everything the branch does in Colombia.
For most SMEs, startups, and standalone market-entry projects, the SAS is the more common choice. Branch offices tend to make sense in narrower, strategic situations, most notably when a company needs to bid on Colombian state contracts using its parent company’s track record, or when it operates in sectors like hydrocarbons where branches are traditionally used.
This guide compares both structures across the factors that actually affect a foreign founder’s decision.
The Core Difference: Legal Personality
| SAS | Branch Office | |
|---|---|---|
| Legal entity | Independent Colombian legal entity | Not a separate entity, same legal person as the parent company |
| Liability | Limited to the capital contributed by shareholders | Parent company is directly liable for all branch obligations |
| Governance | Own bylaws, shareholders, legal representative | Governed by the parent company’s bylaws; managed by a locally appointed legal representative or general agent |
| Formation document | Can be a private document (no notary, in most cases) | Requires a public deed before a Colombian notary |
| Legal basis | Law 1258 of 2008 | Colombian Commercial Code (Articles 469 to 497) |
This single distinction, separate legal person versus extension of the parent, drives almost every other difference between the two structures.
Liability: What’s Actually at Risk
With an SAS, liability is contained within the company. If the business incurs debt or faces legal claims, creditors can generally only pursue the SAS’s own assets, not the parent company’s or the individual shareholders’ personal assets, barring specific guarantees or a piercing-the-corporate-veil scenario.
With a branch office, there is no such containment. Because the branch and the parent are legally the same entity, the parent company remains directly liable for obligations and claims, and creditors and tax authorities can pursue the parent company for the branch’s liabilities. Contracts signed by the branch legally bind the parent, and counterparties can seek recovery directly from the parent’s assets abroad.
If liability containment is a priority, which it is for most standalone market-entry projects, this is usually the deciding factor in favor of the SAS.
Taxation: More Similar Than You’d Expect
At a high level, Colombian tax law treats SAS and branch office operations similarly for most standard taxes. Both structures are generally subject to the same Colombian taxes, since Colombian tax law does not draw major distinctions between a branch office and a subsidiary like an SAS.
The meaningful tax difference shows up in two areas:
- Scope of taxable income. A branch is generally subject to Colombian tax only on Colombian-source income, while an SAS is subject to tax on its worldwide income, though in practice, an SAS operating solely in Colombia is typically taxed on the same Colombian-source income a branch would report.
- Profit repatriation. This is the difference that matters most for cash planning. Branches pay a straight remittance tax on profits sent abroad, while companies like the SAS distribute dividends that are subject to withholding tax for foreign shareholders. The mechanics and applicable rates differ enough that this should be modeled with a tax advisor against your specific repatriation plans before choosing a structure. Don’t decide based on structure alone without running the numbers for your situation.
Governance and Control
An SAS gives shareholders significant freedom to design their own governance rules. Its incorporation process is simple, involves fewer administrative requirements, and shareholders have considerable freedom to determine the company’s operational terms and internal structure.
A branch office, by contrast, operates under centralized control from the parent. A foreign branch has no separate governance bodies of its own. Instead, a legal representative or general agent acts on behalf of the company, reflecting more centralized control from the parent. If your model depends on a fully empowered local team with independent decision-making authority, the SAS structure supports that more naturally.
Setup Complexity and Cost
| Factor | SAS | Branch Office |
|---|---|---|
| Formation document | Private document (notary generally not required, unless assets are contributed as capital) | Public deed before a Colombian notary |
| Parent company documentation | Not required | Certificate of incorporation, board resolution, and bylaws of the parent, all apostilled/legalized and officially translated |
| Relative cost and complexity | Lower | Higher, due to notarization and parent-company documentation requirements |
| Statutory auditor | Not always required, depending on size | Often required |
Because a branch requires legalizing and translating documents from your home jurisdiction (and, if your country isn’t a Hague Convention member, consular legalization instead of a simpler apostille), branch formation generally takes more time and costs more than SAS formation, on top of being a more complex ongoing compliance structure.
One Practical Advantage Branches Have: Track Record
There’s a specific, often-overlooked scenario where a branch outperforms an SAS: bidding on Colombian government contracts. Because a branch office is legally the same entity as its parent, it can draw on the parent company’s industry experience as if it were its own when bidding for public contracts, an advantage an SAS does not have, since an SAS is a separate legal person with its own, separate track record.
If your Colombian entry strategy depends on qualifying for public-sector contracts based on your company’s international experience, this is a legitimate reason to weigh a branch office despite its liability trade-offs.
Decision Framework
| If your priority is… | Consider… |
|---|---|
| Limiting liability to the Colombian operation | SAS |
| Flexibility in governance and shareholder structure | SAS |
| Fastest, simplest, lowest-cost formation | SAS |
| Bidding on Colombian public contracts using parent company experience | Branch Office |
| Operating under your parent company’s exact legal name and identity | Branch Office |
| Sector norms (e.g., hydrocarbons, where branches are traditionally used) | Branch Office |
| Attracting outside investors or eventually raising capital locally | SAS |
For the large majority of founders reading this guide, SMEs, startups, and companies entering Colombia as an independent operation rather than a direct extension of an existing entity, the SAS is the more common and generally more practical starting point. The step-by-step registration process for an SAS is covered in How to Register a Company in Colombia as a Foreigner.
Frequently Asked Questions
Can a branch office later convert into an SAS, or vice versa?
Restructuring between these forms is possible but involves its own legal process rather than a simple conversion. If you anticipate needing to change structures as your business grows, discuss this with your legal advisor before your initial filing so the long-term path is clear from the start.
Does a branch office limit liability at all?
No. A branch is not a separate legal entity, so it does not offer the liability containment an SAS provides. This is the single most important trade-off to weigh against a branch’s advantages.
Which structure is faster to set up?
The SAS is generally faster, largely because it typically doesn’t require notarization or the apostille/legalization of foreign parent-company documents that a branch requires.
Is the SAS available to 100% foreign-owned companies?
Yes. Colombian law does not require local shareholders for an SAS, and a single foreign shareholder can own 100% of the company.
Do both structures require a legal representative in Colombia?
Yes. Both an SAS and a branch office must appoint a legal representative in Colombia, though their scope of authority and how they’re appointed differs between the two structures.
Not Sure Which Structure Fits Your Business?
Choosing between an SAS and a branch office affects your liability exposure, tax planning, and how much control you retain locally. It’s not a decision to make from a generic comparison alone. Start Colombia’s legal and accounting team can assess your specific expansion plan and recommend the structure that fits it.
