According to service-public.gouv.fr, the fine is \u20ac1,500 per undeclared account in a country with which France has a tax treaty, and \u20ac10,000 in other cases.<\/p>\n<\/div>\n<p class=\"wp-block-paragraph\">Your salary is paid into an account in Geneva, Luxembourg, or Brussels. You have opened a savings account and a securities account there. Your French tax return has been filed, but have your accounts been declared?<\/p>\n<p class=\"wp-block-paragraph\">The rules are published on service-public.gouv.fr. They apply to all French tax residents, whether they live near the border or not.<\/p>\n<h2 class=\"wp-block-heading\"><strong>1. Who must declare<\/strong><\/h2>\n<p class=\"wp-block-paragraph\">Individuals who are tax residents of France must declare any accounts they hold abroad. This obligation applies to both account holders and those with power of attorney over the account. A cross-border worker residing in France falls into this category.<\/p>\n<h2 class=\"wp-block-heading\"><strong>2. Fines<\/strong><\/h2>\n<ul class=\"wp-block-list\">\n<li><strong>\u20ac1,500 per undeclared account<\/strong> when the State is bound to France by a convention to combat tax fraud.<\/li>\n<li><strong>\u20ac10,000 per undeclared account<\/strong> in other cases.<\/li>\n<li>An increase of 80 % of the duties due on the sums appearing in the undeclared accounts may replace the fine.<\/li>\n<\/ul>\n<h2 class=\"wp-block-heading\"><strong>3. Fictional example: Sophie, a cross-border worker in Geneva<\/strong><\/h2>\n<p class=\"wp-block-paragraph\"><strong>Situation.<\/strong> Sophie lives in Haute-Savoie and works in Geneva. She has a current account where her salary is paid, a savings account and a securities account, all in the same Swiss bank.<\/p>\n<p class=\"wp-block-paragraph\"><strong>Issue.<\/strong> She declares her Swiss salary every year, but has never declared her bank accounts: she thought that the tax on the salary was sufficient.<\/p>\n<p class=\"wp-block-paragraph\"><strong>Strategy.<\/strong> She lists her accounts with their opening dates and declares them for the next campaign.<\/p>\n<p class=\"wp-block-paragraph\"><strong>Result.<\/strong> Three declared accounts. As a reminder, three undeclared accounts would represent a fine of \u20ac4,500 at a rate of \u20ac1,500 per account.<\/p>\n<p class=\"wp-block-paragraph\"><em>This is an illustrative example; it does not reflect the situation of any particular client.<\/em><\/p>\n<h2 class=\"wp-block-heading\"><strong>4. The list to prepare<\/strong><\/h2>\n<ul class=\"wp-block-list\">\n<li>Each account with its institution, country and opening date.<\/li>\n<li>Accounts for which you have a simple power of attorney.<\/li>\n<li>Life insurance or capitalization contracts taken out abroad.<\/li>\n<li>The opening year, to answer any questions from the administration.<\/li>\n<\/ul>\n<h2 class=\"wp-block-heading\"><strong>Frequently asked questions<\/strong><\/h2>\n<h3 class=\"wp-block-heading\"><strong>Is the account where my salary is paid affected?<\/strong><\/h3>\n<p class=\"wp-block-paragraph\">Yes, provided it is opened outside of France. The obligation applies to the account itself, not to its use.<\/p>\n<h3 class=\"wp-block-heading\"><strong>I am a cross-border worker and my employer is Swiss: am I exempt?<\/strong><\/h3>\n<p class=\"wp-block-paragraph\">The service-public.gouv.fr page does not distinguish according to profession: the obligation applies to people who are tax residents in France.<\/p>\n<h3 class=\"wp-block-heading\"><strong>What if I haven&#039;t declared my accounts in previous years?<\/strong><\/h3>\n<p class=\"wp-block-paragraph\">Please review the situation with us before making any adjustments. Each case is handled individually with your tax office.<\/p>\n<h2 class=\"wp-block-heading\"><strong>Do you have accounts abroad?<\/strong><\/h2>\n<p class=\"wp-block-paragraph\">We take inventory with you and prepare the list to submit to your tax office, then we review the organization of your savings.<\/p>\n<p class=\"wp-block-paragraph\">Are you a tax lawyer, notary or chartered accountant, and some of your clients are cross-border workers? We work in partnership on the investment and life insurance aspects, in conjunction with your tax analysis.<\/p>\n<h2 class=\"wp-block-heading\"><strong>Book an appointment<\/strong><\/h2>\n<p class=\"wp-block-paragraph\">A 30-minute exchange is enough to lay out your situation. <a href=\"https:\/\/calendly.com\/asagnier-balmontconseil\/echange\" target=\"_blank\" rel=\"noopener\">Book a time slot<\/a>.<\/p>\n<p class=\"wp-block-paragraph\"><em>Alexis Sagnier, financial and real estate investment advisor, insurance broker, AMF certified.
