2023 Form 3520 Deadline in 2024 | Foreign Trust Tax Lawyer & Attorney

Form 3520 is one of the most important US international information returns. Due to its severe penalty structure, it is important to file it timely. In this brief essay, I will discuss the tax year 2023 Form 3520 deadline.

2023 Form 3520 Deadline: What is Form 3520

IRS Form 3520 is a US international information return used by the IRS to collect information related to foreign trusts, foreign gifts and foreign inheritance. In essence, Form 3520 collects four types of data from US taxpayers:

  • Certain transactions with foreign trusts;
  • Ownership of foreign trusts under the rules of sections 671 through 679;
  • Receipt of certain large gifts from foreign persons; and
  • Bequests from foreign persons

It is very important that you file Form 3520 timely, because late filing Form 3520 penalties can be very high. For example, a failure to timely disclose a reportable foreign gift on Form 3520 may result in a penalty as high as 25% of the value of the gift. Initial Form 3520 penalty for a failure to report a property transferred by a US transferor to a foreign trust may be as high as 35% of the gross value of the property.

2023 Form 3520 Deadline: Where to File

Form 3520 reporting is complicated by the fact that this form is not filed with a US tax return. Rather, for the tax year 2023, a Form 3520 with all required attachments should be mailed to the following address:

Internal Revenue Service Center
P.O. Box 409101
Ogden, UT 84409

My recommendation is to mail your 2023 Form 3520 by US Certified Mail.

2023 Form 3520 Deadline: When to File

Generally, 2023 Form 3520 deadline will correspond to your US income tax return deadline. In other words, a US person must file his Form 3520 by and including the 15th day of the 4th month following the end of such person’s tax year for US income tax purposes. Same rule applies to Forms 3520 filed by an estate and on behalf of a US decedent. If the due date falls on a Saturday, Sunday, or legal holiday, file by the next day that is not a Saturday, Sunday, or legal holiday.

For individual taxpayers who reside in the United States, this usually means April 15. For example, your 2023 Form 3520 will be due on April 15, 2024.

Moreover, if you are a US citizen or resident and (a) you live outside of the United States and Puerto Rico and your place of business or post of duty is outside the United States and Puerto Rico, OR (b) you are in the military or naval service on duty outside of the United States and Puerto Rico, then your tax deadline will shift to the 15th day of the 6th month (i.e. June 15). In other words, if you satisfy either (a) or (b) above and you are either a US citizen or US resident, then your 2023 Form 3520 will be due on June 17, 2024 (because June 15 is a Saturday this year). You must include a statement with your 2023 Form 3520 showing that you are a U.S. citizen or resident who meets one of these conditions listed above.

Finally, if a US person is granted an extension of time to file an income tax return, the due date for filing Form 3520 shifts to the 15th day of the 10th month following the end of the US person’s tax year. In other words, if you are an individual who filed an extension on your US income tax return, then your 2023 Form 3520 will be due on October 15, 2024.
