Individual Income Tax: rates, deductions & optimization

The Individual Income Tax (IRPF) remains one of the most discussed taxes in the routine of Brazilians. Although the law is complex, its operation follows clear rules that, when understood, allow the taxpayer to fulfill the fiscal obligation without surprises and also take advantage of legal opportunities to reduce the tax due.

How IRPF is calculated

The calculation starts from the taxable income, which includes salaries, rentals, capital gains, investment earnings, and other sources of revenue. On this total amount, the corresponding rate is applied according to the income bracket. Then, the allowed deductions are subtracted, which may include dependents, medical expenses, education, contributions to official retirement plans, and other items provided by law. The final result is the tax due, to be paid or refunded.

Current rates

IRPF rates are progressive, ranging from 0 % to 27.5 %. Income brackets, adjusted periodically, set the limits for each rate. In short:

• Up to approximately R$ 1,903.98 – exempt.
• From R$ 1,903.99 to R$ 2,826.65 – 7.5 %.
• From R$ 2,826.66 to R$ 3,751.05 – 15 %.
• From R$ 3,751.06 to R$ 4,664.68 – 22.5 %.
• Above R$ 4,664.68 – 27.5 %.

These rates are applied marginally, i.e., each portion of income pays the rate corresponding to its bracket.

Main deductions

The Tax Code allows the taxpayer to deduct various expenses, reducing the tax base. Among the most relevant, stand out:

• Dependents: fixed deduction per person, respecting the established limit.
• Medical expenses: consultations, exams, hospitalizations and health plans, with no maximum ceiling.
• Education: expenses with preschool, primary, secondary and higher education, limited to an annual amount per dependent.
• Contribution to official retirement: INSS and private regimes, fully deductible.
• Private retirement (PGBL): up to 12 % of taxable income can be deducted, provided the taxpayer chooses the complete filing.
• Donations: recognized philanthropic entities can generate a deduction of up to 6 % of the tax due.

In addition to these, there is the simplified deduction, which grants a standard discount of 20 % on taxable income, limited to a ceiling set by the Federal Revenue. This option is usually advantageous for those with few deductible expenses.

Filing options

The taxpayer can choose between two modalities:

1. Complete filing: records all deductible expenses. Ideal for those with significant health, education, or pension expenses.
2. Simplified filing: automatically applies the 20 % discount on taxable income, without the need to prove expenses. It is recommended when actual deductions are lower than the simplified limit.

The choice must be made each year, comparing the result of both options to ensure the lowest tax due or the highest refund.

Optimization strategies

Although IRPF is mandatory, several practices allow optimizing the tax burden within legality:

• Medical expense planning: grouping consultations and exams in the same fiscal year can increase the deduction.
• Investment in private retirement: the PGBL plan reduces the tax base, being especially useful for those already using the complete filing.
• Education: anticipating tuition payments or opting for postgraduate courses can expand the benefit.
• Donations: directing resources to cultural or social projects recognized by the Revenue generates direct deduction.
• Capital gains management: selling assets in different years can avoid concentration of income in a single tax bracket.
• Use of dependents: including university-aged children as dependents allows additional deduction, provided legal requirements are met.

In all cases, keeping receipts and invoices is essential to substantiate the filing and avoid assessments.

Conclusion

Mastering the functioning of IRPF, knowing the applicable rates and identifying available deductions are fundamental steps for the Brazilian taxpayer to fulfill tax obligations consciously and, at the same time, minimize financial impact. By adopting optimization strategies – such as using private retirement, planning deductible expenses, and carefully choosing between complete and simplified filing – it is possible to turn the tax obligation into a financial organization opportunity. Thus, the tax ceases to be merely a burden and becomes an integral part of solid and sustainable wealth planning.
