Passive Foreign Investment Companies -Form 8621
One of the most overlooked forms for US expatriates making investments abroad, or any US taxpayer living in the US that invests in foreign mutual funds is Form 8621. If you do not file this form and make certain elections allowed by that form (SEE INSTRUCTIONS TO FORM HERE) you may incur extremely adverse US tax consequences when you finally sell your foreign investment. This form is complex and often difficult to complete due to the elections you must make and the information which must be included in the form. Most taxpayers overlook this form and its important elections because they assume a foreign mutual fund will be treated the same as a US mutual fund. It is not!
WHEN MUST THIS FORM BE FILED? It should be filed when you own a foreign mutual fund (not sold in the US securities market) or you own a foreign corporation that as a major portion of its activities invests in foreign equities, foreign mutual funds and other foreign investments. This form does not
need to be filed is you merely own actual foreign stock certificates, or shares in a foreign corporation that does not produce passive investment income.
Form 8621 is filed annually with your personal tax return. A separate Form must be filed for each separate foreign mutual that you own. If the foreign mutual fund is held in your US stock brokerage account, you do not need to file this form. See The Form 8621 here. Though it appears simple, this form is difficult to complete correctly.
