Labor liability in startups: how to map and reduce risk before a funding round or M&A

Undisclosed labor liability is one of the main risks that stall or lower the value of investment rounds and M&A deals for Brazilian startups.

Updated on 06/18/2026

TL;DR – “PJ” contracts (independent-contractor arrangements using a personal holding company) without objective criteria are the leading source of hidden labor liability in startups. – Terminations without proper documentation multiply the risk of labor court claims. – A backlog in eSocial filings (the digital system for reporting labor, tax, and social security obligations) leads to tax and social security assessments that surface during due diligence. – Mapping liability before a funding round costs less than renegotiating valuation after the fact. – Minimum viable labor compliance doesn’t require a large HR structure — it requires correct processes.

The case no one wants to see in due diligence

A mid-sized tech company was in advanced negotiations with an investment fund. The data room was organized, metrics were solid, the product was validated. Labor due diligence revealed dozens of independent-contractor agreements (“PJ” contracts) with individuals who worked exclusively for the company, kept fixed hours, and were directly subordinate to company managers — none of them registered under the CTPS (Carteira de Trabalho e Previdência Social, the official work-and-social-security record every formal employee in Brazil must have).

The estimated liability to regularize the situation — including FGTS contributions (Fundo de Garantia do Tempo de Serviço, a mandatory employer-funded severance savings account), retroactive termination payments, and social security charges — cut the deal’s valuation by a percentage the founders hadn’t anticipated. The round wasn’t cancelled, but the discount was substantial.

This scenario isn’t an exception. It’s the standard pattern for a company that grew fast, hired under pressure, and never structured its hiring model around clear legal criteria from day one.

The 5 mistakes that most often create labor liability in startups

1. “PJ” contracts without objective criteria for a legitimate independent-contractor relationship

Hiring someone as a “PJ” (Pessoa Jurídica — i.e., engaging an individual through their own personal company rather than as a direct employee) isn’t prohibited, as long as the relationship is genuinely commercial. The problem arises when the service provider:

• works exclusively for the hiring company;
• keeps hours set by the company;
• receives direct, day-to-day orders from a manager;
• has no other clients or doesn’t issue regular invoices.

In these cases, Decree-Law 5,452/1943 (the CLT — Consolidação das Leis do Trabalho, Brazil’s consolidated labor code) — particularly Article 3, which defines “employee” — and settled case law from the TST (Tribunal Superior do Trabalho, Brazil’s Superior Labor Court) point toward recognition of an employment relationship. The 2017 labor reform (Law 13,467/2017) created the “exclusive independent contractor” category, but it comes with specific requirements that startup contracts rarely meet.

The risk: a court ruling recognizing an employment relationship, triggering retroactive FGTS contributions, a 13th-month salary, vacation pay, overtime, and, in many cases, penalties under CLT Article 477.

2. Flexible-hours banking without a valid collective bargaining agreement

Flexible schedules are common in startups, but individual “hour banking” arrangements — provided for under CLT Article 59 — cap the compensation period at six months. Collective bargaining agreements signed with unions can extend that period to one year. Without the backing of a properly registered collective agreement, banked hours turn into overtime owed at a minimum 50% premium, plus knock-on effects on vacation pay, the 13th-month salary, and FGTS.

3. Late or inconsistent FGTS contributions

FGTS is governed by Law 8,036/1990 and must be deposited monthly by the 7th of the month following the reference period. Late payments trigger late-payment penalties, monetary correction, and possible assessment by the Caixa Econômica Federal (the federal bank that administers the fund) and the MTE (Ministério do Trabalho e Emprego, Brazil’s Ministry of Labor and Employment). In due diligence, inconsistent FGTS statements are an immediate red flag for investors.

4. Terminations without proper documentation

Informal termination agreements — whether verbal, by email, or by text message — carry no legal weight as a valid discharge of obligations. The CLT requires:

• A termination statement itemizing all amounts owed;
• Formal approval or digital certification, depending on the applicable procedure;
• Payment of all amounts within the statutory deadline (CLT Article 477, § 6).

A termination without proper documentation exposes the company to a labor claim over unpaid amounts, with no valid paperwork to contest the claims.

5. Incomplete or outdated eSocial filings

eSocial is the digital system for reporting tax, social security, and labor obligations. Events that aren’t filed, or are filed with errors — especially hiring, contract changes, and leaves of absence — create inconsistencies that surface in cross-checks by the Receita Federal do Brasil (RFB, Brazil’s federal tax authority) and the MTE. For startups that have never had formal employees before, onboarding onto the system is a critical step that’s often put off.

Minimum viable labor compliance for startups

You don’t need a fully built-out HR department to operate within labor law. You need correct processes from the very first hire. The table below summarizes what counts as minimum viable compliance:

Compliance isn’t the absence of litigation. It’s the ability to show, with documents, that the company follows the rules — in any due diligence process.

Lower-risk terminations: the checklist

Termination is the moment that accounts for a significant share of labor claims filed against startups. A simple protocol reduces that risk:

1. Define the type of termination before communicating it. The main options are: termination without cause, voluntary resignation, termination by mutual agreement (CLT Article 484-A, introduced by Law 13,467/2017), and termination for cause (CLT Article 482 — an exhaustive list of grounds). Each type has different payment obligations and deadlines.
2. Calculate all amounts owed before paying. Outstanding salary, prior notice, proportional and accrued vacation pay, proportional 13th-month salary, FGTS plus penalty where applicable. Calculation errors are a common cause of labor claims even when the termination was amicable.
3. Put it in writing and obtain a signature. The termination statement must be signed by the employee. If they refuse, it’s advisable to document the attempt.
4. Meet the payment deadline. CLT Article 477, § 6, sets a deadline of up to 10 calendar days after the contract ends, or the next business day if the contract ends on the last day of the month. Failure to comply triggers a penalty equal to the employee’s salary.
5. Report it in eSocial. The termination event must be filed within ten days of the contract’s effective end date.
6. Keep the documentation for five years. The statute of limitations for filing a labor claim is two years from termination (CLT Article 11), but keeping records for five years provides a safety margin covering periods of potential litigation and inspection.

Frequently asked questions

Can an employment relationship be recognized even with a signed “PJ” contract in place?

Yes. A signed contract isn’t the only factor Brazilian labor courts consider. What determines whether an employment relationship exists are the factual elements of the relationship: personal performance (the person provides the service themselves, without substitution), non-occasional nature (the work is regular and ongoing), payment (there’s compensation), and subordination (the hiring company directs how and when the work is done). These four elements are set out in Article 3 of Decree-Law 5,452/1943 (the CLT). When all four are present, a judge can disregard the “PJ” contract — regardless of what’s written on paper. Law 13,467/2017 (the labor reform) created the “exclusive independent contractor” category (Article 442-B), but it requires the service provider to organize their own work and bear the associated risks — conditions rarely met in typical startup hiring arrangements. If you’re unsure about existing contracts at your company, a preventive review lets you address risks with more time and control.

What does an investor look at in a startup’s labor due diligence?

Labor due diligence checks whether a company has hidden liabilities that could affect valuation or create future obligations. The most closely reviewed points are: (1) the ratio of “PJ” contracts to the actual role performed by the service providers; (2) the consistency of FGTS contributions (statements by company tax ID, issued by Caixa Econômica Federal); (3) the history of active and closed labor claims in the PJe system (Processo Judicial Eletrônico, Brazil’s electronic court records system); (4) the regularity of eSocial filings, especially hiring and termination events; (5) the existence of collective or individual working-hours agreements; (6) documentation of terminations over the past five years. Sophisticated investors — and M&A advisory banks — often request a labor-debt clearance certificate and a contingency report. Liabilities identified during due diligence feed directly into price-adjustment calculations or post-closing indemnification clauses. Mapping liability before starting a funding round allows you to address it without time pressure — and without a forced discount.

What’s the difference between termination by mutual agreement and voluntary resignation?

Both result in the employee leaving the company, but they carry different payment obligations and implications. With voluntary resignation, the employee takes the initiative: they don’t receive the 40% FGTS penalty payment, lose the right to unemployment insurance, and must either work through the prior-notice period or compensate the employer for it. With termination by mutual agreement — introduced by CLT Article 484-A under Law 13,467/2017 — employer and employee reach a formal agreement: FGTS is released with a 20% penalty payment (half of what would apply in a termination without cause), the employee receives half of the prior-notice pay and half of the additional severance, but has no access to unemployment insurance. Termination by mutual agreement is useful when both parties want the relationship to end but the employer doesn’t want to bear the full cost of a termination without cause. It requires a written statement signed by both parties — it doesn’t work as a verbal agreement. For startups restructuring their teams, this option tends to be more balanced than a unilateral dismissal, as long as the circumstances allow for negotiation.
