Fourth- and fifth-category income tax in Peru: the difference between freelance and payroll work

The underlying mistake: treating “fourth” and “fifth” as just receipt types

Many people assume the difference between fourth and fifth category is a matter of paperwork — which kind of receipt you issue — rather than something more fundamental. Peru’s Income Tax Law distinguishes them by the nature of the relationship. Article 33 says fourth-category income comes from independent work:

“Son rentas de cuarta categoría las obtenidas por: a) El ejercicio individual, de cualquier profesión, arte, ciencia, oficio o actividades no incluidas expresamente en la tercera categoría. b) El desempeño de funciones de director de empresas, síndico, mandatario, gestor de negocios, albacea y actividades similares…”

Article 34 defines fifth-category income by dependence instead:

“Son rentas de quinta categoría las obtenidas por concepto de: a) El trabajo personal prestado en relación de dependencia, incluidos cargos públicos, electivos o no, como sueldos, salarios, asignaciones, emolumentos, primas, dietas, gratificaciones, bonificaciones, aguinaldos, comisiones, compensaciones en dinero o en especie, gastos de representación y, en general, toda retribución por servicios personales.”

Article 34 also lists, in subsections b) through f), pensions, workers’ profit-sharing, income from labor cooperatives, and certain independent-contractor income the law treats as fifth category because of the conditions under which it’s performed. But the core distinction is this: fourth category is working for yourself, fifth category is working under someone else’s direction.

How each one is withheld — and why 8% doesn’t mean you owe nothing

Here’s the second common misunderstanding: assuming a recibo por honorarios means “nothing withheld until I file.” That’s not how it works. Article 74 requires whoever pays you to withhold 8% of your gross income on every payment:

“Tratándose de rentas de cuarta categoría, las personas, empresas y entidades a que se refiere el inciso b) del artículo 71 de esta Ley, deberán retener con carácter de pago a cuenta del Impuesto a la Renta el 8% (ocho por ciento) de las rentas brutas que abonen o acrediten.”

That 8% is withheld every time, no matter how much you earn over the year. It’s an advance — a “payment on account” — toward your annual tax, not the final tax itself. If your net income (after the deductions described below) ends up owing less than what was withheld, SUNAT refunds the difference when you file your annual declaración jurada.

Fifth-category withholding works differently: article 75 requires the employer to withhold monthly, not a flat percentage, but a fraction of the estimated annual tax:

“Las personas naturales y jurídicas o entidades públicas o privadas que paguen rentas comprendidas en la quinta categoría, deberán retener mensualmente sobre las remuneraciones que abonen a sus servidores un dozavo del impuesto que, conforme a las normas de esta ley, les corresponda tributar sobre el total de las remuneraciones gravadas a percibir en el año.”

That “twelfth” (one-twelfth of the projected annual tax) is recalculated during the year as your pay changes — which is why the deduction in a month with a bonus, gratification or raise usually isn’t the same as a regular month’s.

The deduction almost nobody calculates correctly: 20% + 7 UIT

The reason many freelancers and modest-income employees end up owing no income tax at all comes down to two deductions applied in sequence.

First, only against fourth-category income, article 45 allows an automatic 20% deduction from gross income, with no need to substantiate expenses, capped at 24 UIT per year:

“Para establecer la renta neta de cuarta categoría, el contribuyente podrá deducir de la renta bruta del ejercicio gravable, por concepto de todo gasto, el veinte por ciento (20%) de la misma, hasta el límite de 24 Unidades Impositivas Tributarias. La deducción que autoriza este artículo no es aplicable a las rentas percibidas por desempeño de funciones contempladas en el inciso b) del Artículo 33° de esta ley.”

That last sentence matters: if your fourth-category income comes from acting as a director, trustee, agent, business manager or estate executor (subsection b of article 33), you do not get this 20% deduction.

Second — and this is where most people miscalculate — article 46 gives an additional fixed deduction of 7 UIT, but not one per category: a single 7 UIT on the sum of your fourth- and fifth-category income together:

“De las rentas de cuarta y quinta categorías podrán deducirse anualmente, un monto fijo equivalente a siete (7) Unidades Impositivas Tributarias.”

If you have a payroll job and also invoice as a freelancer, you don’t get 7 UIT for each: you get 7 UIT total across both income streams combined. Added to the 20% deduction (capped at 24 UIT) already subtracted from your fourth-category income, this combined deduction is why many people with modest income — fourth category only, fifth category only, or both — end up owing no tax, or even qualifying for a refund of what was withheld.

Foreigners

If you’re domiciled in Peru and earn fourth- or fifth-category income here — whether working independently or on payroll — these same withholding and deduction rules apply to you regardless of nationality. If you’re not domiciled, the withholding treatment differs and is not covered on this page.

About suspending withholding

SUNAT offers an online procedure, commonly known as the “suspensión de retenciones y/o pagos a cuenta de cuarta categoría,” for people who project annual income below the thresholds of the deductions described above. It’s mentioned here as general background, not as a cited legal claim: it is not part of this page’s verified fuentes, so confirm it directly through SUNAT’s official channels before relying on it.
