Glossary: Side Gigs, Passive Income and Investments¶

Key terms used throughout this topic. Entries are in Brazilian Portuguese where the term is used in Portuguese in practice, with English explanation.

Terms¶

Renda Passiva (Passive Income)¶

Income that continues to be generated without continuous active effort after the initial setup or investment. Examples include dividends from FIIs, interest from CDB, and royalties from a digital course on Hotmart. True passive income requires up-front work (money invested, content created) but generates ongoing returns with minimal maintenance. Contrasted with [[#renda-ativa]].

Renda Ativa (Active Income)¶

Income that requires continuous direct effort to be generated — if you stop working, the income stops. A salary from a CLT job, hourly freelancing, and consulting fees are all active income. Most people start with 100% active income and work toward building passive income streams alongside it.

MEI (Microempreendedor Individual)¶

A simplified legal entity registration for individual entrepreneurs in Brazil. MEI allows solo workers to formalize their business activities, issue notas fiscais, access INSS benefits (aposentadoria, auxílio-doença), and pay taxes at a flat monthly rate (DAS) regardless of revenue, up to an annual revenue limit (R$ 81.000 in 2024). Registration is free and done online at gov.br. See Module 02.

CNPJ (Cadastro Nacional da Pessoa Jurídica)¶

Brazil's business tax identification number — the company equivalent of CPF. When you register as MEI, you receive a CNPJ automatically. Clients require your CNPJ to pay you formally and to deduct your service fees from their own taxes.

Dividendos (Dividends)¶

Distributions of profits paid by companies or funds to their shareholders or quotaholders. In Brazil, dividends paid by publicly traded companies (ações) are currently exempt from income tax for individuals. Dividends from FIIs are also exempt for individuals holding less than 10% of the fund's quotas, provided the fund has at least 50 quotaholders. See Module 07 and Module 08.

FII (Fundo de Investimento Imobiliário)¶

A Brazilian real-estate investment fund (REIT equivalent) traded on B3. FIIs pool investor capital to buy and manage real estate assets (shopping centers, logistics warehouses, office buildings, hospital buildings) or real-estate debt securities (CRIs). By law, FIIs must distribute at least 95% of their semi-annual profits as dividends. See Module 08.

Tesouro Direto¶

The Brazilian federal government's program allowing individual investors to buy government bonds directly online starting from R$ 30. Bonds include Tesouro Selic (post-fixed, tracks the SELIC rate), Tesouro IPCA+ (inflation-linked with fixed spread), and Tesouro Prefixado (fixed nominal rate). All are backed by the Brazilian federal government — the lowest credit risk available in Brazil. See Module 06.

CDB (Certificado de Depósito Bancário)¶

A fixed-income security issued by banks to raise capital. CDBs pay a percentage of the CDI rate (e.g., 110% CDI) or a fixed rate. Protected by the FGC (Fundo Garantidor de Créditos) up to R$ 250.000 per CPF per institution. Subject to income tax via tabela regressiva. See Module 06.

LCI / LCA (Letra de Crédito Imobiliário / do Agronegócio)¶

Fixed-income securities issued by banks to fund real estate (LCI) or agricultural (LCA) credit operations. The key advantage: exempt from income tax for individual investors. This makes LCI/LCA very competitive against CDB when comparing net (after-tax) returns. See Module 06.

CDI (Certificado de Depósito Interbancário)¶

The overnight interbank lending rate in Brazil. CDI tracks very closely to the SELIC rate and serves as the primary benchmark for most Brazilian fixed-income investments. When a CDB pays "110% do CDI," it means the annual yield equals 1.10 × the CDI rate. Understanding CDI as a benchmark is essential for comparing any renda fixa investment.

SELIC (Sistema Especial de Liquidação e Custódia)¶

Brazil's base interest rate, set by the Comitê de Política Monetária (COPOM) of the Banco Central do Brasil. SELIC directly determines the return on Tesouro Selic bonds and sets the floor for all other Brazilian interest rates. In 2020–2021, SELIC fell to a historic low of 2% per year; by 2023, it had risen back to 13.75%. Understanding SELIC cycles is fundamental to investment timing in Brazil.

IRPF (Imposto de Renda Pessoa Física)¶

Brazil's personal income tax, declared annually to the Receita Federal via the Programa IRPF. Investment income (renda variável gains, CDB interest, rental income) must be reported. Some sources are exempt (LCI, LCA, FII dividends within the rules). The annual declaration deadline is typically April 30. See Module 10.

GCAP (Ganho de Capital)¶

Capital gains — the profit from selling an asset (ação, FII quota, real estate, crypto) for more than you paid. In Brazil, capital gains on ações sold in a single month are exempt from tax if total sales do not exceed R$ 20.000 (isenção para pequenos investidores). Above R$ 20.000, gains are taxed at 15% for most assets. Tax must be paid via DARF by the last business day of the month following the sale. See Module 10.

DARF (Documento de Arrecadação de Receitas Federais)¶

The payment slip used to pay federal taxes in Brazil outside of the annual IRPF declaration. Investors use DARF to pay capital gains tax on stock sales (due monthly when applicable), Carnê-Leão on self-employment income, and other federal tax obligations. DARFs are generated and paid via e-CAC or the SICALC system. See Module 10.

Carteira Diversificada (Diversified Portfolio)¶

An investment portfolio that spreads risk across multiple asset classes, sectors, and geographies. In the Brazilian context, a well-diversified portfolio typically includes renda fixa (Tesouro Direto, CDB), FIIs, ações/ETFs on B3, and potentially international exposure via BDRs or offshore investments. Diversification reduces the impact of any single investment performing poorly.

Aporte (Regular Investment Contribution)¶

The periodic addition of new capital to an investment portfolio. Making regular monthly aportes, regardless of market conditions (dollar-cost averaging principle), is one of the most powerful wealth-building behaviors for long-term investors. A R$ 500/mês aporte maintained for 20 years at CDI returns produces dramatically different results than sporadic larger investments. See Module 01 for worked calculations.
