In brief
What changed with the 2026 labour reform (Act No. 27,802), why invoicing under the monotributo simplified-tax regime no longer offers full protection, and how to safeguard contracts with freelancers and contractors.
Almost every Argentine startup begins the same way: little capital, plenty of urgency and a team assembled entirely on an invoice basis. The developer, the designer, the community manager, the outside accountant—all registered under the monotributo regime, all “service providers.” It is fast, it is cheap and, on paper, it looks tidy. The problem is that this structure conceals one of the most expensive and underestimated legal risks in the startup ecosystem: the reclassification of the relationship as one of employment.
With the 2026 labour reform the landscape changed, but the risk did not disappear. It changed form, and understanding it properly today makes the difference between scaling with peace of mind and facing a claim that, for a young company, can be fatal.
The governing principle: primacy of reality
Argentine labour law is governed by a principle that no contract can sidestep: the primacy of reality. It means that, in the event of a dispute, what matters is not how the relationship was labelled on paper but how it actually operated in practice. If a person invoices as a monotributista but in fact works like an employee, the courts will treat that person as an employee, with all the consequences that entails.
Put differently: the invoice is a formality; the reality of the work performed is what defines the relationship. A judge may look behind the paperwork and reconstruct what truly took place.
What changed with the 2026 labour reform (Act No. 27,802)
The Labour Modernisation Act amended Section 23 of the Employment Contract Act. Previously, the mere rendering of services gave rise to an automatic presumption that an employment relationship existed, and it was the company that had to prove otherwise. Now, that automatic presumption does not apply where there is formal invoicing through the monotributo regime or other registered payment mechanisms.
The most significant practical effect is the shift in the burden of proof: anyone claiming to have in fact been an employee must now establish, in detail, the actual conditions under which the work was carried out. This is a clear improvement for companies, although it is by no means a blank cheque.
The trap: why invoicing is not a shield
Here lies the costliest misunderstanding. Many founders read the reform as meaning “there is no longer any risk with monotributistas.” That is false. The reform weakened the automatic presumption but left the primacy of reality fully intact. Judges retain full authority to examine how the work was actually performed and to reclassify the relationship if signs of subordination are present.
The focus of the analysis has shifted to the degree of autonomy. The key question is no longer “does the person invoice?” but “does the person work as a genuinely independent contractor or as a disguised employee?”
The three forms of subordination a judge assesses
The courts examine whether the following three types of subordination exist. The more of them that are present, the closer the relationship is to disguised employment:
- Legal subordination: the company gives instructions, controls how the task is performed, sets working hours, requires on-site attendance or permanent availability, and may impose disciplinary measures.
- Technical subordination: the person follows the methods, tools and processes defined by the company, exercising no independent judgement as to how the work is carried out.
- Economic subordination: the company is effectively the person’s sole client, pays a fixed monthly amount akin to a salary, and the person’s livelihood depends on it.
Warning signs vs. a sound relationship
These are the red flags that, taken together, tend to tip the balance towards reclassification:
- Exclusivity: the contractor invoices a single company, month after month.
- A fixed monthly amount, always the same, resembling a salary rather than a project-based fee.
- Working hours and place of work imposed by the company.
- Use of corporate email, company tools and an internal chain of command.
- Long tenure (years) performing tasks central to the business.
- Compliance with daily instructions and reporting, like any other employee.
Conversely, the following reinforce autonomy and the company’s position:
- ✓ The contractor has several clients and can demonstrate it.
- ✓ The contractor organises their own schedule and working methods.
- ✓ The contractor invoices per project, deliverable or outcome, not a fixed identical monthly amount.
- ✓ The contractor uses their own tools and bears the business risk of their activity.
- ✓ The contractor may delegate or subcontract part of the work.
The cost of getting it wrong
Reclassification is not a technicality: the company may be ordered to pay outstanding social-security contributions, severance pay, the proportional part of the month, payment in lieu of notice, and unpaid holiday and statutory bonus entitlements, with interest currently adjusted by the consumer price index plus an additional rate. For an early-stage startup, a single claim of this kind can jeopardise an entire funding round, or the very viability of the project.
There is a further aggravating factor for those raising capital: in any due diligence, investors review how the team is engaged. A workforce entirely structured under the monotributo regime performing core functions is a contingency that shows up in red and can stall or reduce the value of the deal.
How to safeguard the startup: a practical guide
- Document genuine autonomy. Use a clear independent-services agreement: a project- or deliverable-based scope, a defined term, the absence of exclusivity, and freedom as to methods and schedule.
- Invoice by results, not by presence. Avoid the same fixed monthly amount year after year; payment should be tied to milestones or deliverables wherever possible.
- Avoid the hallmarks of employment. No imposed working hours, no mandatory on-site attendance, no chain of command and none of the disciplinary measures typical of an employee.
- Distinguish core from support functions. Permanent functions central to the business tend to be employment relationships; these are best kept on the payroll.
- Take advantage of formalisation incentives. The reform introduces reductions in employer charges that make it cheaper to register the key team.
- Review before every round. The engagement structure should be audited with an employment lawyer before going out to raise investment.
Conclusion
The 2026 labour reform gave startups genuine breathing room: not every invoice now triggers a presumption against the company. But the underlying message is clear: form does not prevail over reality. So long as subordination exists, the monotributo regime does not operate as a shield. The good news is that, with well-designed contracts and a genuinely independent relationship, it is now easier than ever to work with independent contractors—provided that reality matches the paperwork.
When a team invoices entirely under the monotributo regime, it is wise to review the contracts before the next round. An hour of prevention costs far less than an employment lawsuit.
