Taxes on your investment

Every form of income has a tax treatment, including a stake in a private company. This guide explains the general mechanism in simple terms and points out the mistakes that show up most often on the return. Nothing here replaces advice from a professional: rules can be changed by law and shift over time, so check your own case with an accountant.

1. How the investment appears on the income tax return

For an individual, the starting point is the Assets and Rights section of the annual return. The contribution is reported as an asset, and the reference value is what you paid, called the acquisition cost. The general rule is to report at cost, and not at an estimate of the company's value after the contribution.

The Federal Tax Authority's program organizes these assets into groups and classification codes. As a rule, a stake in a Brazilian company falls into the group dedicated to shares. You do not need to memorize anything: the return itself guides the choice within the program, and the applicable code is the one the form indicates for your type of asset.

If you sell only part of the stake, the return usually shows the amount still invested and the result of the part sold. The sale receipts are what allow you to report this correctly.

2. The two mistakes that happen most often

• Reporting the contribution and forgetting to report the exit. Redeeming does not erase the investment, because the return has no cancellation line. The contribution and the result of the deal go into the assessment separately and are evaluated independently.
• Reporting in the wrong year. The reference year is the year in which the taxable event happened, that is, the year of the contribution and the year of the exit, not the year you happened to remember. A contribution in December and an exit the following year are two separate tax years.

Mistakes on the return can be corrected by filing an amended return. Until that is done, the inconsistency remains on record and can trigger a notice. Amending is usually easier than leaving it for later, because time passes and memory is not a document.

3. The practical difference between equity participation and a convertible instrument

In an equity participation, the result usually appears in two forms: distribution of profits or dividends when the company decides to distribute, and capital gain when the stake is sold for more than was invested. Each of those events has its own assessment date.

With a convertible instrument, the result usually comes from the remuneration of the amount invested while the instrument is not converted, and from capital gain on the conversion or the sale, if there is one. The treatment depends on the structure set out in the agreement, because the same label can hide different structures.

The question that settles almost every doubt is simple: what exactly did I receive, and on what date. Identifying the taxable event is the first step, and the agreement settles the rest.

4. Withholdings charged on payments

Part of the amounts paid or credited may arrive with tax already withheld at source, especially when the payment is made to a legal entity. In practice, the net amount received is lower than the gross amount of the deal, and the difference shows up as a withholding on the document itself.

• Check whether the deal documentation separates the gross amount, the withholding and the net amount.
• Add up the withholdings over the year so you do not forget them in the assessment.
• Keep the receipt for each withholding: it is used both on the return and for any refund.

Withholding at source is not a final tax. As a rule it works as an advance payment, and the amount can be offset or refunded according to the final assessment. The percentages and the exceptions change over time, so confirm the applicable rule with an accountant.

5. Documents you should keep

• The investment agreement, the participation contract or the signed instrument.
• The statements of the contributions and of the amounts received.
• The income statement, when provided by the platform or by the company.
• The deal notes showing the gross amount, the withholdings and the net amount.
• The documents for the sale of the stake, the conversion or the redemption, where they exist.

The general retention rule is five years, counted from the end of the tax year to which the documents relate, a period close to the time in which a return can be reviewed. Keeping them longer does no harm; keeping them for less than that does. A document that was not filed is a document you cannot prove.

6. When to call an accountant

• When the deal represents a significant part of your net worth.
• When there is a sale of the stake, a conversion of the instrument or a liquidation of the company.
• When you also invest as a legal entity.
• When you receive distributions of profits in years other than the year of the contribution.
• When the company proposes an exit plan or a corporate restructuring.

A conversation with an accountant resolves in an hour what usually takes weeks of trying on your own. If the question is only how to fill in a line on the return, ask any professional. If the question involves the entire structure of the investment, call an accountant and take the agreement with you.
