How do I indicate income from investment in securities (dividends, stocks, bonds, crypto, interest, etc.)?

In the "Tax situation" form, in the category "Other revenues", tick "I received income from investments (dividends, stocks, crypto, etc.)." and save.

Then you will be able to see the "Investment in securities" form.

Once you have selected the type of investment income, you must indicate the gross amount in euros, as well as the country of origin.

👉 If the income comes from abroad and has already been taxed at source, please indicate the amount of foreign tax withheld. This will allow a tax credit to be calculated and deducted in your Luxembourg tax return.

👉 If the interest comes from Luxembourg and a withholding tax has been applied (according to the RELIBI law), you do not need to declare this income, as the taxation is considered final.
