Please note withholding tax applies to all clients who are resident in Ireland, whether individuals (including partnerships) or companies. 

Withholding tax does not apply to clients who are companies in countries that are members of the European Union (excluding Ireland) or companies in countries that have a Double Tax Agreement (DTA) with Ireland.  

For other clients in the EU (excluding Ireland) or if you are a non-resident of Ireland but tax resident in a country with a Double Tax Agreement (DTA) with Ireland, you may complete Form 8-3-6, that will reduce or eliminate your withholding tax. In addition to providing your information, you will need to have the form completed by the tax authority in the country where you are a tax resident.

You will require the following information in order to complete Form 8-3-6.

 1.       Client name (please ensure this matches the name on your IBKR account).

 2.      Client address.

 3.       Tax reference number in country of residence.

 4.       The country in which the client is resident for tax.

 5.       The rate of withholding tax between the country of tax residence and Ireland (see below).

 6.       Signature.

 7.       Date.

On completion of the form, you should submit it to the local tax authority in the country of your residence.  The local tax authority must sign and stamp the form. As per below, Form 8-3-6 has been translated into French, German, Spanish, Italian and Dutch.

Once you receive the completed form from your local tax authority, please email a PDF or JPEG copy of the fully signed form to tax-withholding@interactivebrokers.com.

Please note, the withholding tax rate depends on the DTA between Ireland and your country of tax residence which can be found on the Irish Revenue website https://www.revenue.ie/en/tax-professionals/tax-agreements/rates/index.aspx

For your convenience, we have prepared the forms to include items 3 to 5 above for all countries in the European Economic Area (“EEA”).  Clients will need to complete the other items in 1 to 7 above.

For clients outside the EEA please use this form when the withholding tax rate is 0% and this form in all other cases.

1.         EEA countries with 0% Withholding Tax.

2.       EEA countries with rates above 0% Withholding Tax.

3.              Other countries with a DTA with Ireland (* denotes where there is 0% withholding tax in all situations).
