Tax Regimes in Chile: The Silent ProPyme Mistake

What the Tax Authorities automatically assign when you register your company may not be right for your actual situation.

When an entrepreneur decides to formalize their business and incorporate a company in Chile, the process can seem straightforward at first glance. Yet behind the forms and filings handled through the Internal Revenue Service   known in Chile as the Servicio de Impuestos Internos (Tax Authorities) lies a decision of enormous consequence that many business owners make without even realizing it: the choice of tax regime.

When a new company is created, the Tax Authorities automatically assigns it to the ProPyme General Regime (Art. 14 D No. 3). While well-intentioned   since it benefits the majority of small and medium-sized businesses   this default assignment can become a serious problem if the ownership structure and related-party revenues are not carefully reviewed.

What Are Tax Regimes?

Tax regimes are the frameworks that determine how a company calculates, reports, and pays its taxes. In Chile, following the Tax Modernization Law (Law No. 21,210 of 2020) and its subsequent amendments, the system is organized around four main options:

The UF (Unidad de Fomento) is a Chilean inflation-indexed unit of account. Its value adjusts daily based on the previous month's CPI, protecting contracts and payments from losing real value. Used widely for mortgages, rent, insurance, and real estate. Always paid in pesos at the day's rate.

Today (May 20, 2026): 1 UF = $40,424.99 CLP

The ProPyme Regime: Why It's So Attractive

The ProPyme regime is designed to reduce the tax burden on small and medium-sized enterprises (SMEs). Its main advantages include:

• A corporate income tax rate of 25%, which is lower than the 27% rate applied under the general regime.

• Full integration of the corporate tax credit against shareholders' final taxes (Global Complementary or Additional Income Tax), thereby avoiding economic double taxation.

• Simplified accounting: taxable income is determined on a cash-flow basis (revenues received and expenses paid), which eliminates the complexities associated with the accrual method.

• Exclusive tax benefits for SMEs, including a special credit for fixed asset investments and VAT payment deferral.

• Reduced overall compliance costs for accounting and tax filings.

The Critical Requirement: The 75,000 UF Revenue Cap

To qualify for   and remain in   the ProPyme regime, a company must meet several requirements, the most important being that its annual net revenues must not exceed 75,000 UF. This figure is approximately equivalent to CLP 2.7 billion (reference value for 2025–2026).

At first glance, this seems straightforward. The problem emerges when we look closely at who the shareholders actually are.

The Hidden Trap: The Corporate Shareholder

Chilean tax regulations establish that, for purposes of determining compliance with the ProPyme revenue cap, the revenues of related entities must also be taken into account   including those of any shareholder that is itself a legal entity.

In practical terms: if a holding company, investment vehicle, or any other corporate entity holds shares in the newly created company, its own revenues are added to the calculation of the revenue ceiling.

Which Rules Govern Related-Party Relationships?

Article 14 D of the Income Tax Law, read in conjunction with Article 8 No. 17 of the Tax Code, sets out the related-party rules that determine when two entities must consolidate their revenues for ProPyme cap purposes. Entities are considered related, among other situations, when:

• A legal entity holds a direct or indirect stake of 10% or more in the capital or profits of another.

• Two companies share common shareholders or partners with 10% or greater participation.

• One entity exercises de facto or de jure control over another, even if the ownership thresholds above are not met.

• Two or more companies share common directors, managers, or administrators.

  
  

Consequences of Operating Under the Wrong Regime

Remaining in the ProPyme regime without meeting its requirements is not a mere formality   it carries concrete tax consequences.

• Tax underpayments: The applicable rate under the general regime is 27%, not 25%. The difference must be settled retroactively, with adjustments and interest.

• Improperly claimed credits: Shareholders who applied a 100% corporate tax credit against their personal taxes may owe additional amounts in personal Income Tax or Additional Income Tax for foreign shareholders

• Penalties and fines: The Tax Authorities may impose sanctions for improperly accessing SME-exclusive tax benefits.

• Retroactive complexity: Correcting the situation years later requires amending tax returns, recalculating withholdings, and potentially revisiting profit distributions or dividends already paid to shareholders.

How to Proceed Correctly:

Before incorporating a company   or when reviewing an existing one   it is essential to conduct a proper analysis covering the following steps:

• Map the full ownership structure: Who are the shareholders or partners? Is any of them a legal entity?

• Identify all related entities: Apply the rules of Article 8 No. 17 of the Tax Code to determine which entities must be consolidated.

• Project consolidated revenues: Add the new company's projected revenues to those of all related entities and verify whether the 75,000 UF threshold is exceeded.

• Select the appropriate regime: If consolidated revenues surpass the cap, the General Regime (Art. 14 A) is the correct choice from day one.

• Formalize the election within the legal deadline: Changing tax regimes is subject to specific deadlines and conditions. Failing to act in time can generate additional costs.

Conclusion

The ProPyme regime is a genuinely valuable tool for hundreds of thousands of small and medium-sized businesses in Chile. Its advantages in terms of tax rates, integration, and accounting simplification are real and meaningful.

However, the Tax Authorities 's automatic assignment at the time of incorporation does not guarantee that the regime is always the right fit. When the ownership structure includes legal entities as shareholders or partners, the related-party rules require their revenues to be considered in the cap calculation   potentially disqualifying the company from ProPyme without the taxpayer being aware of it.

The solution lies in proactive tax planning: understanding the rules, analyzing each company's specific structure, and making informed decisions from the outset. In taxation, what goes unreviewed today almost always costs more tomorrow.
