The Internal Revenue Services (IRS) is the government agency responsible for US federal taxes.

The Foreign Account Tax Compliance Act (FATCA) is a law that requires all financial institutions and banks outside the US to report the financials accounts of their US persons directly to the IRS.

For US tax purposes a US person is a citizen of, or a resident in the United States. US persons are required to report their worldwide income to the IRS regardless of where they live. The US grants citizenship to all those born on US territory. Therefore, anybody born in the US will have a filing obligation regardless of the period of time spent in the US.

A “green card” holder is also a US person, and is for most purposes the same as a US citizen.

Regardless of whether or not you reside or work in United States, in general all US citizens and green card holders are required to file a yearly tax return with the Internal Revenue Service “IRS”.

There are several income exceptions to this and the minimum income requirements for 2020 are as follows for Most Taxpayers:

Certain non-U.S. persons also need to file tax returns. Those persons are called resident aliens. There are clear rules for who need to file or not.

Whether you or your family members are considered resident aliens (non-US citizens) for US income tax purposes is significant because if you are, you will be taxed on your worldwide income and will be obliged to comply with substantial reporting.

Subject to certain exceptions, you will only be subject to US income tax on US source income.

The answer to this question depends upon (a) your immigration status; (b) the number of days in which you are physically present in the US; and (c) your connections to another country.

Green card holders are automatically residents of the U.S. and therefore required to file U.S. income tax returns.

If you are physically present in the US for 183 days or more in any calendar year, you are generally considered a resident.

There is a test called the “substantial presence test” which is applied to both the current year and the two preceding years. The application of this test to your factual situation will determine whether you are deemed resident for U.S. income tax purposes.

The “substantial presence test” is applied on a calendar year basis, and an individual meets the substantial presence test with respect to a current calendar year if:

1. he/she is physically present in the US on at least 31 days during the current calendar year; and
2. the sum of the number of days on which the individual is considered to be present in the US in the current calendar year and the 2 preceding calendar years, when multiplied by an “applicable multiplier,” equals or exceeds 183 days.
3. The applicable multiplier for the current year is 1; for the first preceding year, 1/3; and for the second preceding year, 1/6.

Any fractional days resulting from the above calculations will not be rounded to the nearest whole number.

To illustrate the application of the formula, if a person was physically present in the United States for: (i) 120 days in 2013, (ii) 120 days in 2014, and (iii) 125 days in 2015, He/She will meet the substantial presence test for 2016, as he/she will have spent a total of 185 days over that period according to the formula.

This total is calculated as follows:

• For the year 2015, in which the person was physically present in the US for 125 days, the formula is as follows: 125 x 1 = 125 days.
• For the first preceding year, namely for 2014, in which the person was physically present in the US for 120 days, the formula is as follows: 120 x 1/3 = 40 days
• For the second preceding year, namely for 2013, in which the person was physically present in the US for 120 days, the formula is as follows: 120 x 1/6 = 20 days.

The application of the formula leads to the conclusion that this person has spent a total of 185 days, which exceeds the 183-day limit permitted in any calendar year, such that the person will be considered a US tax resident.

Even if the application of the above formula might lead to a different conclusion, in such a scenario, you would not be considered to be US tax resident if, for the current year— (1) you were present in the US on fewer than 183 days, (2) you maintained a tax home in a foreign country, and (3) you had a closer connection to that foreign country than to the US This exception to the substantial presence test is known as the “closer connection exception”. You need to file Form 8840 with the US Internal Revenue Service (IRS) to claim this exception. You are not eligible for this exception for the current year if, at any time during such year, you had an application for adjustment of status pending or took other steps to apply for lawful permanent resident status (e.g., you applied for the green card).

Generally, your days of physical presence in the US as an exempt individual, or due to a medical condition that arose in the US preventing you to leave the US, are not counted as days of physical presence in the US for purposes of making the calculations under the substantial presence test.

You might still be able to claim that you are a non-resident alien for US income tax purposes by filing a treaty-based return position.

To qualify, you generally need to be a tax resident of a foreign country that has an income tax treaty with the US and be treated as a tax resident of such country under the treaty’s “tie-breaker” rules. You need to file Form 8833 with the IRS to notify the IRS that you are claiming to be a non-resident pursuant to a treaty. If you hold the green card and file a treaty-based return, you might jeopardize your permanent resident status for US immigration purposes and might be considered to have terminated such status for US income tax purposes (with any resulting tax consequences).

US persons and resident aliens living in the US – Due April 17, 2021

US persons living outside of the US – Due June 15, 2021

When taxpayers have both Non-US and US assets, sometimes it’s more difficult to collect your documents in time to file your return by the initial due date of April 15. If this is the case, extensions called Form 4868 can be filed as follows:

FinCen Form 114, Report of Foreign Bank and Financial Accounts (FBAR) is a form filed separately from your US federal income tax return, due on 15 April of each year. However, FinCEN will grant those People seeking to file who do not meet the April 15 deadline with an automatic extension to October 15. Unlike your annual tax return, you cannot file an extension for this form. The purpose of the FBAR is to report all your non-US bank or financial accounts that were open in a calendar year. An account is considered reportable on the FBAR if you held the account individually, jointly, or had signature authority over the account. There are separate parts of the FBAR, each indicating which of these categories describes your relationship to the account.

The form requires amongst other things that the US person list the maximum value of each account during the year. If the aggregate value of all your accounts equals less than USD 10,000 in a calendar year, you are not required to file this form. If the aggregate value of all your accounts exceeds USD 10,000, then you must file this form.

Form 8938 is similar to an FBAR, but is actually filed as part of the US federal tax return.  While anyone with over USD 10,000 aggregate in their bank account must file an FBAR, the account balances that require this form to be filed are much higher. This form is only necessary when the value of the asset exceeds the following:
