Do you have foreign investments? Here’s how to declare your tax preferences

Update your tax preferences to avoid double taxation on income generated from your foreign investments with Walliance

Written by Sarra

Each year, from January 1 through March 31, you may indicate to the companies in which you have invested, or in which you will invest during the year, how you would like taxes on income derived from your investments made through Walliance to be handled.

This choice is relevant if your country of tax residence is different from the country of tax residence of the issuing company or the company distributing the income.

In such cases, a Double Taxation Treaty may apply between the two countries. Depending on the type of income and the countries involved, the treaty may provide for a reduced withholding tax rate, an exemption, or the possibility of subsequently claiming a refund of taxes paid in excess.

To enable Walliance to communicate your tax preferences to the issuing company, you must upload to your personal area a valid tax residency certificate and, where required, the treaty documentation applicable to the relevant type of income and country.

Please note: Walliance performs a preliminary review of the uploaded documentation; however, the actual application of the tax treatment remains the responsibility of the company paying the income, where that company acts as the party responsible for withholding tax or applying the relevant tax treatment.

❌ You do not need to update your tax preferences if

your country of tax residence is the same as the country of tax residence of all issuing companies associated with the projects in which you have invested or will invest.

Example: you are a tax resident of Italy and have invested, or will invest, only in projects offered by Italian companies.

✅ You should update your tax preferences if

your country of tax residence differs from even one of the countries of tax residence of the issuing companies associated with the projects in which you have invested or will invest.

Example: you are a tax resident of Italy and have invested, or will invest, in projects offered by French or Spanish companies. Alternatively, you are a tax resident of another country and have invested in a project offered by an Italian company.

If in doubt, you can check the tax residence of the company in which you invested directly in the project page, under the “Issuer” section.


Which document must you provide?

To request application of treaty benefits, you must provide a tax residency certificate issued by the competent tax authority of your country of tax residence.

The document must relate to the tax year in which the income is paid.

The certificate must be suitable for purposes of applying the Double Taxation Treaty between your country of tax residence and the country of the company paying the income. In particular, it must certify your tax residence for treaty purposes or under the applicable tax laws of your country of residence.

A generic tax residency certificate is not sufficient because it does not meet the required criteria. For purposes of applying Double Taxation Treaties, a certificate specifically issued for that purpose is required. In particular, the document must:

  1. be valid for the relevant tax year;

  2. certify the taxpayer’s tax residence;

  3. expressly state that it is requested for purposes of applying the Double Taxation Treaty between the investor’s country of residence and the country in which the project company is established.

Depending on the country, the type of income, and the applicable regulations, you may also be required to provide a specific treaty form or supplementary declaration.

For example, in order to obtain direct application of treaty benefits to dividends, interest, royalties, or other income paid by a foreign company, additional information may be required, including:

  • a declaration that you are the beneficial owner of the income;

  • an indication of the type of income received;

  • identification of the company paying the income;

  • a request for application of the treaty rate, exemption, or other treaty benefit;

  • a declaration that the income is not connected with a permanent establishment or fixed base in the source country;

  • any tax forms required by the source country or agreed upon by the tax authorities of the two countries.

ℹ️ Documents other than the required tax certificate and treaty documentation are not considered acceptable, including civil registry certificates, utility bills, employment contracts, salary certificates, residence permits, identity cards, or other documents not issued by the competent tax authority or that do not allow verification of the conditions required for treaty benefits.

Must the certificate be issued for each country?

Yes. If you have investments in multiple foreign countries, you must provide appropriate documentation for each country in which the companies associated with your investments are tax residents.

For example, if you are a tax resident of Italy and have invested in projects offered by French and Spanish companies, you must provide two certifications: one valid for purposes of the Italy–France treaty and one valid for purposes of the Italy–Spain treaty.

How to request a tax residency certificate

The tax residency certificate must be requested from the tax authority of the country in which you are a tax resident.

For example, if you are a tax resident of Italy, the certificate must be requested from the Italian Revenue Agency (Agenzia delle Entrate). If you are a tax resident of France, Spain, or another country, you must contact the competent tax authority of that country.

When making the request, we recommend specifying that the certificate is needed for purposes of applying a Double Taxation Treaty with the country in which the issuing company or the company paying the income is established.

Where available, it is preferable to use the form prescribed by the tax authority of the source country or by the applicable treaty. Alternatively, equivalent documentation may be accepted, provided it allows the company paying the income to verify and retain all information required for application of treaty benefits.

How to upload the certificate on your personal area

Go to your “Account” > “Services” > “Taxation” area, where you can:

  • verify that the country of tax residence listed in your account is correct;

  • update your tax preferences;

  • request, where available, the application of the treaty regime;

  • upload your tax residence certificate and any supporting documentation;

  • confirm the declaration using an OTP.

If the country of tax residence listed in your account is incorrect, you'll need to update it first in the “My Data” > “Verify Identity and Address” section.

What happens after you upload the documentation?

When the income is paid, Walliance will conduct a preliminary review of the documentation received and will communicate your tax preferences to the issuing company.

The company paying the income will assess, at that time and with the support of its advisors if necessary, whether the documentation received is sufficient to apply treaty benefits directly, where available.

Any application of a reduced rate, exemption, or other treaty benefit remains the responsibility of the company paying the income, within the limits and responsibilities established by applicable law.

What happens if you do not upload the certificate by March 31?

If you do not upload the required documentation by March 31, it will not be possible to update your tax preferences for the current year through the platform.

In that case, the company paying the income will apply the ordinary tax treatment provided under the laws of the source country, unless it determines otherwise.

You may still consult your tax advisor to determine whether any excess taxes paid can be recovered through your tax return, a foreign tax credit, a refund procedure, or other mechanisms available under applicable law.

What happens if you cannot obtain the certificate?

If you are unable to obtain the tax residency certificate or the required treaty documentation, your ability to invest will not be affected.

However, you may be unable to benefit from direct application of treaty benefits at source. In that case, any excess taxes paid may be addressed later in accordance with the tax rules applicable in your country of residence and in the source country.

We recommend consulting your tax advisor to determine the most appropriate treatment based on your individual circumstances.

ℹ️ Important

  • Tax documentation must be issued by the competent tax authority or otherwise be suitable to demonstrate the requirements established under the applicable Double Taxation Treaty.

  • The certificate must relate to the correct tax year.

  • Uploading documentation does not automatically guarantee application of treaty benefits. The final determination rests with the company paying the income, based on applicable law and the documentation received.

  • Double Taxation Treaties do not always provide for a full exemption from tax in the source country. In many cases, they only provide for a reduced tax rate or the possibility of claiming a refund of any excess tax paid.

  • At present, the system allows only one PDF document to be uploaded. If you need to provide multiple documents, please combine them into a single PDF file before uploading them to your personal area.

  • After March 31 of each year, it will no longer be possible to update tax preferences for the current year through the platform.
