RESUMEN El presente artículo tiene como objetivo determinar si los principios de progresividad y proporcionalidad se cumplen en el impuesto a la renta, tal como este se encuentra establecido en el régimen tributario ecuatoriano. Para cumplir con dicho propósito se aplica una metodología que se sustenta en la revisión bibliográfica de literatura académica en torno a variables como: impuesto a la renta, progresividad y proporcionalidad; así como en la revisión documental de información oficial y de normativa tributaria nacional. Se concluye ratificando que tanto el principio de progresividad como el de proporcionalidad se cumplen en la aplicación del impuesto a la renta en el sistema tributario ecuatoriano, particularmente cuando se establecen porcentajes diferenciados para los distintos ingresos de las personas naturales. Sin embargo, es en la tarifa del 25% que se aplica a la base imponible de las sociedades, donde se evidencian visos de incumplimiento del principio de progresividad. ABSTRACT The purpose of this article is to determine whether the principles of progressivity and proportionality are complied with in the income tax, as it is established in the Ecuadorian tax system. To fulfill this purpose, a methodology is applied based on a bibliographic review of academic literature on variables such as income tax, progressivity, and proportionality, as well as on a documentary review of official information and national tax regulations. It is concluded by ratifying that both the principle of progressivity and the principle of proportionality are complied with in the application of income tax in the Ecuadorian tax system, particularly when differentiated percentages are established for the different incomes of individuals. However, it is in the 25% rate applied to the taxable income of corporations where there is evidence of non-compliance with the principle of progressivity.
