LCI vs LCA: Key Differences, Tax Exemption Rules, and How to Choose

Short answer: LCI and LCA are nearly identical — the main difference is the sector each security finances (real estate vs. agribusiness). For individual investors (pessoa física), both are exempt from Income Tax, so the choice rarely comes down to the product name; it comes down to the interest rate offered, the maturity term, and the liquidity of each specific issuance.

What Are LCI and LCA?

LCI (Letra de Crédito Imobiliário, or Real Estate Credit Note) and LCA (Letra de Crédito do Agronegócio, or Agribusiness Credit Note) are fixed-income securities issued by banks to finance the real estate and agribusiness sectors, respectively. In practice, you are lending money to a financial institution and receiving it back with interest, typically linked to the CDI rate or set at a fixed rate.

If you are just starting out, it is worth reviewing the fundamentals in our complete guide to fixed income investments before comparing securities.

The Difference Between LCI and LCA

Since the mechanics are practically the same, the name "LCI" or "LCA" matters less than the interest rate, maturity term, and redemption conditions of each specific offer.

Income Tax Exemption: The Main Attraction

LCI and LCA earnings are exempt from Income Tax for individual investors — a rule currently in effect that may be changed by future legislation. It is worth noting that in 2025, there was legislative discussion about taxing these products (MP 1.303/2025), which expired in October 2025, and the exemption remained in place. Nevertheless, this is a point to monitor before making new investments.

Two important details:

• The exemption applies only to individuals. For legal entities (PJ), earnings are taxed according to general rules.
• Tax rules may change; check your earnings statement and current legislation at the time of investment.

Lock-Up Period and Liquidity: Why LCI/LCA Are Not Suitable for an Emergency Fund

LCI and LCA have lock-up periods and, in practice, are not suitable for an emergency fund. Check the minimum redemption period of each security before investing. In most cases, redeeming before maturity means forfeiting the agreed-upon returns.

If the goal is funds that need to be available at any time, a emergency fund in daily-liquidity options is usually more appropriate, as discussed in our comparison of CDB, Tesouro Selic, and savings accounts.

FGC Protection

LCI and LCA are covered by FGC (Fundo Garantidor de Crédito) protection of up to R$250,000 per CPF per financial institution, within a global limit of R$1 million every 4 years. This means that if the issuing bank goes bankrupt, the Fund reimburses the investor up to that ceiling.

An important detail: the limit applies per institution. If you hold R$200,000 in LCI at Bank A and R$200,000 in LCA at Bank B, each amount is protected separately. Learn more in our article on FGC protection and its limits.

How to Compare LCI/LCA with CDB: The After-Tax Yield

Income Tax exemption alone does not guarantee a better return. To make a proper comparison, calculate the after-tax yield: a CDB needs to pay a higher gross rate than an exempt LCI to deliver the same net return.

Illustrative example (not a comparison of current offers): an LCI paying 90% of CDI, because it is exempt from tax, may be equivalent to a CDB paying approximately 109% of CDI over a 360-to-720-day period, the bracket in which the CDB Income Tax rate is 17.5%. Beyond 720 days, the rate drops and the equivalent percentage would be lower (around 106% of CDI). The exact number depends on the Income Tax bracket applicable to the CDB's maturity — use the method's logic, not the fixed number.

When in doubt, calculate with concrete figures: our article on how much R$1,000 earns in a CDB shows the step-by-step after-tax calculation.

Common Mistakes When Investing in LCI and LCA

1. Looking only at the Income Tax exemption and ignoring the rate: an LCA at 75% of CDI may yield less than a CDB at 110% of CDI, even after the IR deduction.
2. Using them as an emergency fund: the lock-up period prevents redemption without loss.
3. Concentrating everything in a single bank: amounts exceeding R$250,000 per institution lose FGC protection on the excess.
4. Assuming the exemption is permanent: it is a current rule, subject to legislative change.
5. Not checking the maturity and liquidity of each issuance: terms vary significantly between banks.

FAQ

LCI or LCA: which yields more? There is no fixed answer. Both are exempt from Income Tax for individuals; what determines the return is the rate of each specific issuance. Always compare the after-tax yield with other fixed-income options.

Do LCI and LCA have FGC protection? Yes, up to R$250,000 per CPF per financial institution, within a global limit of R$1 million every 4 years.

Can I redeem LCI or LCA before maturity? Generally, no — without losing returns. These securities have lock-up periods, and the minimum term varies by issuance. Check the specific terms before investing.

Does the Income Tax exemption apply to companies? No. The exemption applies to individuals; for legal entities, earnings are taxed according to general rules.

Can the exemption be removed? It is a current rule, but may be altered by future legislation. In 2025, there was an attempt to change it (MP 1.303/2025), which expired and kept the exemption in place.

Conclusion

LCI and LCA are very similar fixed-income securities: the core difference is the sector they finance (real estate or agribusiness), not the return potential itself. For individual investors, both offer the current Income Tax exemption, FGC protection up to R$250,000 per institution, and, in return, a lock-up period that makes them unsuitable for an emergency fund.

The practical decision is conditional: if you have funds that can remain invested until maturity, want to diversify across institutions, and find a competitive rate compared to equivalent CDBs, LCI or LCA may make sense. If the money may be needed at any moment, prioritize liquidity. In any case, always compare the after-tax yield — not just the "Income Tax exempt" label.
