Understand the Obligatory Declaration
Have you ever wondered whether your fixed-income investments really need to be declared? The answer depends on specific rules that many people don't know about. A Internal Revenue Service establishes clear criteria, but it's easy to get confused by the details.

Criteria defined by Receita Federal
Two main factors define the obligation: total balances and income. If you have more than R$140 in applications on the last day of the year or taxable income above R$ 33,888.00, you must declare.
Even exempt amounts, such as savings, require attention if they exceed R$ 200,000 per year.
O income statement of financial institutions is your ally. It details exactly what will appear in the tax authorities' database. Compare these figures with the Assets and Rights avoid dangerous disagreements.
When do you need to declare?
Imagine having R$ 50,000 in CDBs and R$ 20,000 in LCIs. Even if part is exempt, the total assets rights above R$ 800,000 makes declaration compulsory. Case studies show that even small investments can add up to significant amounts over time.
Don't underestimate low values. A forgotten R$ 300 title could lead to future questions. The rule is clear: everything in the report must appear in the declaration, without exception.
Fixed Income Investment Profile
Choosing between the various types of fixed income can be more complex than it seems. Each asset has specific taxation and declaration rules that directly impact your tax liability.
Types of assets and their characteristics
The Treasury Direct securities are the leading taxable investments. They follow the regressive table: the longer you keep them, the lower the tax rate.
LCIs and LCAs, on the other hand, are exempt for individuals, but require caution when it comes to their use. declaring investments - even if they don't pay IR, they need to be included on the Assets and Rights sheet.
- CDB and RDB: Taxed according to term (22.5% to 15%)
- Savings: Exempt, but declarable if balance exceeds R$ 200 thousand
- Debentures: Tax varies between 15% and 20%
Taxable and exempt income
In 2025, the difference between taxed and tax-free investments remains crucial. See practical examples:
| Active | Taxation | Minimum Term |
|---|---|---|
| IPCA+ Treasury | 15%-22,5% | 6 months |
| LCI 90 days | Exempt | 3 months |
| CDB 360 days | 15% | 1 year |
A common mistake is to think that income investments exempt do not need attention. In fact, they should appear in the declaration with a specific code. Taxable securities, on the other hand, require details of the income received in the previous year.
Remember: the regressive income tax table does not apply to all assets. While Tesouro Direto has decreasing rates, CDBs follow different rules depending on the issuer. Always check your income statement to avoid surprises!
How to Identify Your Investments in the Income Report
Your fixed-income investments generate crucial tax reports - do you know how to interpret them correctly? This document, provided by banks and brokers, is the key to an accurate declaration.
It contains data that the tax authorities already know, and any discrepancies can trigger alerts.

The balance reported on the last day of the year must correspond to your statement. Pay special attention to the redemption date: investments redeemed before maturity may be taxed differently.
Separate the taxable income the exempted ones carefully. While CDBs and Tesouro Direto appear in the taxable section, LCIs and LCAs appear in the exemptions section.
Investment funds require different analysis: some follow variable income, even when investing in fixed-rate securities.

Practical Guide for Declaring Fixed Income Earnings on Your Income Tax Return
Did you know that 35% of taxpayers make mistakes in the first steps of their tax return? It all starts with the correct choice of codes in the income tax program. The Assets and Rights is where your fixed income comes to life before the tax authorities.
Initial steps in the declaration
When it comes to declare income, Your first move is to select group 04 on the corresponding tab. Use code 02 for taxable securities (CDBs, Treasuries) and 03 for exempt income (LCIs, LCAs). Don't forget to include:
- Complete CNPJ of the financial institution

Step by Step: Declaration of Securities such as Tesouro Direto and CDBs
Reporting fixed-income securities requires attention to specific details that ensure compliance with the tax authorities. Let's unravel the process so you can avoid common mistakes in the tax return this year.
Filling in the “Assets and Rights” form”
In the Applications and Investments, select the code corresponding to your security. For Tesouro Direto and taxable CDBs, use code 02. Enter:
- Complete CNPJ of the broker or bank
- Original amount invested (acquisition cost)
- Precise date of operation
A CDB bought for R$ 5,000 in March should be listed with this value, not the updated amount. This step is crucial for those who need to declare multiple assets simultaneously.
Entering income on the specific form
The income received goes into the Income subject to exclusive taxation. Check out this comparison table:
| Active | Code | Income tax rate | Mandatory Information |
|---|---|---|---|
| Treasury Direct | 02 | 15%-22,5% | Purchase date, nominal value |
| CDB | 02 | 15%-22,5% | Issuing CNPJ, deadline |
Redeemed income must be declared even if IR has already been withheld at source. A investment statement requires accuracy: differences of more than R$1 between your report and the data entered may generate a notification.
Remember: bonds with a maturity of less than 180 days have a maximum rate (22.5%). Always use the acquisition cost never the updated value. This practice avoids distortions that lead to a fine mesh.
How to declare fixed-income investment funds
Did you know that fixed-income funds have different rules when it comes to tax returns? The IRS classifies these investments into two main categories, each with a specific treatment. Understanding this division is essential to avoid mistakes.
Long-term funds
For assets with an average term of more than 365 days, the IR rate gradually decreases. Check out the regressive table:
| Application Period | Rate |
|---|---|
| Up to 180 days | 22,5% |
| 181 to 360 days | 20% |
| 361 to 720 days | 17,5% |
| Over 720 days | 15% |
On the form Assets and Rights, Use code 07 to declare the total value of the shares on 31/12. Don't forget the fund's CNPJ and the date of acquisition.
Short-term funds
In this category (up to 365 days), rates are less flexible:
- Up to 180 days: 22.5% of IR
- Over 181 days: 20%
The yields must appear in the Capital Gains. A crucial detail: even exempt funds need to be reported. For full guidelines, see our guide to tax returns.

Declaring Other Fixed Income Assets
Less conventional assets require extra attention when filling in your tax return. Did you know that even securities traded on the stock exchange have specific rules? Mastering these details is your insurance against problems with the tax authorities.

Debentures, LCIs, LCAs and other securities
To common debentures, If you have a tax return, use code 02 on the Assets and Rights form. Incentives (infrastructure), on the other hand, are treated differently - even if they are exempt, they require a declaration with code 03. Check out practical examples:
| Active | Code | Declaration location |
|---|---|---|
| LCI 180 days | 03 | Assets and Rights |
| Incentivized Debenture | 03 | Exempt Income |
| LCA 360 days | 03 | Assets and Rights |
Income from exempt securities must appear in the specific section, even without taxation. A frequent mistake is to declare the updated value - always use the original amount invested.
Crucial tip: compare the data in the report with your brokerage notes. Differences in value applied or dates of operation generate inconsistencies. Keep receipts for 5 years for possible proof.
In 2025, the IRS expanded its inspection of these assets. Declaring correctly avoids questions about the origin of the funds. Remember: transparency is the best strategy!
Common Mistakes and Tips for Avoiding the Fine Mesh
Want to avoid the fine mesh? The secret lies in the details that many ignore when declaring fixed income investments. A single wrong digit or incorrect code can trigger automatic alerts from the IRS.
Take care with your tax return
Copying data from the document automatically is a sure trap. Check manually:
- CNPJ of the financial institution (must match the IR registration)
- Exact balance and income figures (cents matter!)
- Tax codes (exempt ≠ non-declarable)

Make this checklist before sending:
| What to check | Common mistake | Solution |
|---|---|---|
| Asset codes | Use 02 for LCIs | Use code 03 |
| Application dates | Confusing purchase with expiration | Check contract |
| Original value | Declare updated balance | Enter the amount invested |

Regressive Income Tax Table for Fixed Income
Knowing how to calculate taxes correctly can increase your income by up to 7% a year. The regressive table is your ally when it comes to paying less tax - as long as you understand how it works.
Understand the rates according to the application period
The Brazilian tax system rewards patient investors. The longer you keep your money invested, the lower the rate charged. Here's how it works in practice:
- Up to 180 days: 22.5% of IR
- 181 to 360 days: 20%
- 361 to 720 days: 17.5%
- Over 720 days: 15%
Imagine investing R$ 50,000 in a 3-year CDB. If you redeem it after 700 days, you'll pay 17.5%. But if you wait another 30 days, the rate drops to 15% - a difference of R$ 1,250 in tax!
“The term strategy must take into account both financial objectives and taxation. Holding a bond for another 20 days can be worth thousands of reais”
