Northern Mariana Islands
Moderate relevanceTrusts in the Northern Mariana Islands, the Settlement Fund likely among them, are foreign trusts for Forms 3520 and 3520-A, and residents who are citizens are U.S. persons, though their income tax return goes to the Commonwealth. A bona fide resident who relies on the 2024 proposed regulations reports nothing for a trust located there.

The Settlement Fund was created by the settlement of Johnson v. Inos, approved by the U.S. District Court for the Northern Mariana Islands; it took over assets of the NMI Retirement Fund to pay the members of the settlement class at least 75% of their full defined benefit pensions, from annual payments the Commonwealth government must make to it.1,2

Likely a foreign trust: its court, though federal, sits in a territory.
Likely a foreign trust, if the Fund is a trust. For the court test a court includes any federal, state, or local court, but the United States means only the States and the District of Columbia, and a court within a territory is not a court within the United States;3,4 on those words, a federal court sitting in the Northern Mariana Islands is not a court within the United States, so the Fund fails the court test. No ruling addresses the point.

An employer-funded fund read as a Β§404(a)(4) or Β§402(b) trust; retirees are paid, not contributors now.
Its money comes from the Commonwealth government, the employer, and from the former Retirement Fund's assets,1,2 so it reads as an employees' trust: Β§402(b) if it does not meet Β§401(a), and the trust Β§404(a)(4) describes if it would meet Β§401(a) but for its location.5,6 Either way you are not treated as owner of a part funded by the employer,7,8 and pension payments are taxed under Β§402 and Β§72 when paid.9,10 A bona fide resident of the Commonwealth files the income tax return for them with the Commonwealth.11

Proposed regulations: possible for a bona fide resident. Rev. Proc. 2020-17: not settled.
If you are a bona fide resident of the Commonwealth and rely on the 2024 proposed regulations, which you may do now if you apply them in full and consistently with related persons,12 sections 6048(a) to (c) do not apply to a trust located in a mirror code possession to the extent the person who must report, you or, at your death, your executor, is a bona fide resident there.13 The Commonwealth is a mirror code possession: the income tax there is the U.S. income tax, read with the Commonwealth in place of the United States.14,15 A trust is located there if a court there can exercise primary supervision over it and one or more bona fide residents control all its substantial decisions,16 and a bona fide resident is someone present there at least 183 days in the year, with no tax home or closer connection elsewhere.17 The app asks both questions when you rely on the proposed regulations. For the Settlement Fund, located there turns on whether bona fide residents of the Commonwealth control all its substantial decisions; the U.S. District Court for the Northern Mariana Islands sits there. Without relying, the cautious course is to keep filing: the proposal would not need this exception if section 6048 did not already reach bona fide residents.13

Whether a U.S. territory is a foreign jurisdiction is not settled, and no IRS guidance answers it. For it: the revenue procedure is written for trusts that are foreign for U.S. tax purposes, which a territory's trusts are;20,4 the Code treats a company organized under a territory's law as foreign, because only the States and the District of Columbia are the United States, and the Joint Committee on Taxation says entities organized there are generally foreign persons;21,22,23 the IRS's examination manual says the territories are generally treated as foreign for U.S. tax purposes unless the Code says otherwise;24 and the Form 8938 reporting the revenue procedure gives as a reason for the exemption counts an account at a territory's financial institution as a foreign asset.25,26 Against it: the revenue procedure and the 2024 preamble explain the exemption by the restrictions imposed under the laws of the country where the trust is established,27,28 and a territory is not a country. The Code names foreign countries and U.S. possessions separately, and Treasury defines a foreign country as territory under another government's sovereignty.29,30 The FBAR rules count the territories as part of the United States,31 and a bona fide resident of a territory leaves accounts at its own institutions off Form 8938,32 so the duplicate reporting the revenue procedure relies on may not exist for them. The 2024 proposal deals with territory trusts in an exception of their own, by the filer's residence and only for some territories.13 The proposed regulations' exemption for retirement and savings trusts uses the same words as the revenue procedure, so the same doubt applies to it.33 Until the IRS says, the cautious course is not to rely on either exemption for a trust in a U.S. territory, and to report it in full.

On our reading that an IRA set up under Commonwealth law with a local trustee is a foreign trust; no IRS guidance addresses it. A bona fide resident who relies on the proposed regulations files none of these for an account located there; an executor reporting a death is spared only if also a bona fide resident.
Because the Code is the Commonwealth's income tax law with the Commonwealth in place of the United States, an individual retirement account under Commonwealth law is the U.S. kind, a trust created or organized in the United States for an individual's exclusive benefit, read as created in the Commonwealth.52,55 Only the individual pays in. No IRS guidance addresses these accounts.

A trust set up under Commonwealth law, during someone's life or by their will, in which a trustee holds investments or a business for family members.46 If the trustee mainly runs a business for profit rather than holding property for the family, U.S. law may classify the arrangement as a business entity rather than a trust.61

A U.S. person who transfers property to the trust is treated as owner of the part it funds for any year in which the trust has a U.S. beneficiary,8 and a U.S. citizen living in the Commonwealth is a U.S. person, as is any family member who is a U.S. citizen or resident.62 Someone who funds the trust while not a U.S. resident and becomes one within 5 years is treated, for this rule and for Part I, as transferring that part of the trust on the day their U.S. residency starts.63 A settlor who is not a U.S. person is treated as owner only if they can revoke the trust alone or with the consent of a related or subordinate party subservient to them, or if only they or their spouse can receive distributions during their life.64 Otherwise, unless another grantor trust rule makes a U.S. person owner,56 no one is owner, and the trust is taxed as a separate, non-grantor trust.65

A trust has a U.S. beneficiary for the transferor rule if anyone has discretion to pay or benefit any person, unless its terms identify the class who may benefit and none of them is a U.S. person that year,66 even if nothing is paid to a U.S. person that year;67 a power to amend the trust to benefit a U.S. person counts, and so does a letter of wishes or other understanding that points to benefiting one, even one that says it is only a suggestion.68 Where a U.S. person funds the trust, the IRS may treat it as having a U.S. beneficiary unless that person shows it has none.69 A beneficiary who first became a U.S. person more than 5 years after the transfer is not counted,70 and a transferor whose trust gains a U.S. beneficiary is taxed that year on the income the trust kept for that part to the end of the year before, as an accumulation distribution with the interest charge.71,72 A settlor who is not a U.S. person keeps the revocable-trust exception for a year only if they can take the property back alone, or with the consent of a related or subordinate party subservient to them, for at least 183 days of it; a power that needs anyone else's consent, such as an independent trustee's or protector's, does not count.73,74 Once the exception fails for a year it is lost for good.75 Separately, a portion already treated as owned under Β§676, or under Β§677 other than its life insurance rule, on September 19, 1995 keeps that owner for the property it held that day, for as long as it stays so treated.76 A U.S. settlor of a trust with no U.S. beneficiary can still be owner under another rule, for example by keeping a power to take the property back,77 and a U.S. beneficiary who alone can take the property is owner of it.78,64

When a settlor who was not a U.S. person dies, the revocable-trust and spouse-only exceptions end for that settlor's portion, because the person left with the power, even a surviving spouse, is not its grantor;79 a U.S. person who alone can take the property, or a U.S. person who funded the trust, can still be owner, and otherwise the portion is taxed as a non-grantor trust.78,8,65 When a portion stops being owned by a U.S. person, the owner is treated, for the gain rule, as transferring it to a foreign trust that day.80 At death the gain is excused only if the trust's basis in the property is then reset to its value at death under section 1014(a), as where the owner could still revoke the trust;81 otherwise the owner is treated as transferring it immediately before death and recognizes the gain.82

As for any foreign trust, unless a bona fide resident relies on the proposed regulations.
A U.S. person who transfers property to the trust files Part I for that year.57 A transfer to a foreign trust is treated as a sale, and you recognize any gain on what you transfer;83 a transfer is not, to the extent anyone is treated as owning the part it funds.84 Part I also applies on the death of a U.S. citizen or resident who was treated as owner of any part of the trust, or whose gross estate includes part of it, and to property that passes to the trust by reason of a U.S. person's death; the executor reports it, whether or not the executor is a U.S. person.58 The gain rule does not apply to property that passes to the trust by reason of a U.S. person's death, if its basis in that property is set under section 1014(a).81 A U.S. owner files Part II and makes sure Form 3520-A is filed, or files a substitute, each year.50,59 A U.S. beneficiary who receives a distribution files Part III for that year.37 A distribution from a non-grantor trust that carries out income the trust kept in earlier years is an accumulation distribution, taxed with an interest charge on Form 4970.85 Form 4970 can also apply to a transferor taxed when the trust gains a U.S. beneficiary, as the owner step says.72 Owing no U.S. tax on the trust's income does not remove any of these: transfers and distributions are reportable whether or not they have U.S. income tax consequences.86 Rev. Proc. 2020-17 does not apply: it covers only retirement trusts and medical, disability, or educational savings trusts.87

A distribution is any gratuitous transfer from the trust, whether or not it is a grantor trust and whether or not you are named as a beneficiary, including a credit card bill it pays or guarantees and a check written on its account.88 On the proposed rules, a payment from a company the trust owns to a U.S. person who is a grantor, owner or beneficiary of the trust, or related to one, is treated as a distribution from the trust, unless that person shows it is properly attributable to their own interest in the company.89,12 A loan of cash or marketable securities, or use of trust property, to you or a related U.S. person goes on Part III whether or not it is taxable;90 it is treated as a distribution for income tax, except a loan made on a qualified obligation (a written loan in U.S. dollars, for 5 years or less, at an interest rate tied to the federal rate, for which you extend the IRS's time to assess and that you report each year) or use you pay the fair market value for within a reasonable time,91,92,93,94 and where a U.S. person funded the trust, the loan instead makes it a grantor trust, and it still goes on Part III.95

If you are the U.S. owner of the part that pays you, you complete only lines 24 and 27, and the rest of this paragraph does not apply to you.96 Otherwise, with a complete Foreign Grantor Trust Beneficiary Statement you treat a payment as coming from the owner, so a gift from the owner is not your income;97 without one, the default method applies even to a distribution from a grantor trust.98 From a non-grantor trust you may use the actual method if you have a Foreign Nongrantor Trust Beneficiary Statement,99 and without one the default method applies: the part of this year's distributions above 1.25 times the average of the three years before is an accumulation distribution, taxed on Form 4970 with an interest charge figured on Form 3520's Schedule C, and the rest is ordinary income,100,85,101 and once you use the default method you must keep using it in later years, except that in the year the trust ends you may use the actual method if you have the statement.102 In the trust's first year as a foreign trust, you stop Part III once you have entered how many years it has been foreign, so no accumulation distribution is figured that year.103 The statute treats the whole distribution as an accumulation distribution where adequate records are not given;104 the default method is the IRS's relief from that, open if you can give the trust's distributions for the three years before,105 and where there were none, it too makes the whole distribution an accumulation distribution.100 A foreign trust's distributable net income, the income its distributions carry out, includes its capital gains,106 and the exception for income kept before a beneficiary was born or turned 21 does not apply to it.107

If you are a bona fide resident who files your income tax return in the Commonwealth, not with the IRS,11 how the gain and accumulation distribution rules above apply is a question for that return, which this guide does not cover; the reporting above does not change. Reporting the trust's income on a Commonwealth return does not file anything with the IRS. A bona fide resident of the Commonwealth who relies on the proposed regulations files none of these for a trust located there, to the extent of their own part as transferor, owner, or recipient, and an executor reports a death unless the executor is a bona fide resident too; a U.S. person living elsewhere still reports.13,16 FBAR (FinCEN Form 114) and Form 8938 are separate and may also apply.108

Gifts and inheritances
You report gifts and bequests on Form 3520 Part IV when, in one tax year, you receive more than $100,000 from a nonresident alien individual or a foreign estate, counting gifts from persons related to them together,109 or more than $20,116 (for 2025) or $20,573 (for 2026) from foreign corporations or foreign partnerships, adding in gifts from foreign persons related to them.110,111,112 Tuition someone pays directly to a school for you, and payments made directly to a medical provider for your care, are not foreign gifts and do not count.113,114 If you rely on the 2024 proposed regulations, the $100,000 is adjusted for inflation, to about $201,160 for 2025 and $205,730 for 2026,115 and gifts from a covered expatriate (a former U.S. citizen or long-term resident covered by section 877A) received from January 14, 2025 are reported once the year's total passes $19,000.116 A gift that is late or left off Part IV is charged 5% of its amount for each month the failure continues, up to 25%.117 The IRS's own procedures no longer assess that penalty when a late Form 3520 reporting gifts arrives, but the law is unchanged and an examination can still assert it.118

The Covenant brought only the U.S. income tax laws into force in the Commonwealth, as a local income tax, and lets the Commonwealth add taxes of its own;119,120 no gift tax or estate tax of the Commonwealth's own was found for this guide, which is not confirmed. Most people born in the Commonwealth before the Covenant took effect became U.S. citizens under it,121 and Northern Mariana Islanders who chose to become U.S. nationals instead of citizens are U.S. nationals.122 A national who is not a citizen and has no green card is a nonresident alien, so a gift from one counts toward Part IV.123,124 Part IV turns on whether the giver is a nonresident alien. A U.S. citizen living in the Commonwealth is not one, so a gift from them is not reported on Part IV.109,123 A giver who is not a U.S. citizen and has no green card can be one even after years in the Commonwealth, because days in a territory do not count toward the substantial presence test.125 For the U.S. gift and estate taxes, a citizen living in a territory whose citizenship came only from the territory, by birth, residence, or its citizenship, is treated as a nonresident not a citizen,126,127 which changes the giver's own U.S. gift tax, not your Part IV.

Whether the estate of someone who lived in the Commonwealth is a foreign estate for Part IV is not settled. A foreign estate is one whose income from outside the United States is not in its U.S. gross income,128 and no IRS guidance applies that to an estate administered in a territory. The cautious course for a bequest of more than $100,000 in a year from such an estate is to report it on Part IV.109
128 26 U.S.C. Β§7701(a)(31)(A)
109 Instructions for Form 3520, Who Must File
Money from a foreign trust goes on Part III, not Part IV, even if it is a gift for income tax purposes.129,97 Money passed to you by someone who received it from the trust can go on Part III too, where it was part of a plan to avoid U.S. tax: the regulation presumes that plan where you are related to, or otherwise close to, a grantor of the trust and receive the money within two years before or after the intermediary's receipt, unless you show otherwise, and it does not apply where the intermediary is the grantor or your year's total from foreign trusts is $10,000 or less.130,131,132 A gift paid by a foreign company can be taxed as a distribution from it instead,133 and so can a payment from a trust a foreign company funded.134 A distribution from a domestic trust treated as owned by a foreign person goes on Part IV, as a gift from that person, counted toward the $100,000 threshold above.135,109 If a foreign trust, a plan read as one included, pays the estate of someone who has died, and the estate is a U.S. person, which it is unless it is a foreign estate,136 the executor reports the payment on Part III for the estate, as any U.S. person reports a distribution.137 Rev. Proc. 2020-17 and the proposed exemption cover an eligible individual's transactions, and an estate is not an individual, so on our reading they do not reach it.138,139 A bona fide resident who relies on the 2024 proposed regulations does not report money from a trust located in the Commonwealth on Part III, to the extent of their bona fide residence, as the trusts block says.13

Penalties and practical notes
A Form 3520 that is late, incomplete, or wrong is penalized at the greater of $10,000 or 35% of the amount involved: the value transferred, for a transfer missing from Part I, or the distributions received, for a distribution missing from Part III.140,141 When a trust's Form 3520-A is late or incomplete, the U.S. owner owes the greater of $10,000 or 5% of the trust assets the owner is treated as owning at the end of the year.142 If a failure continues more than 90 days after the IRS mails a notice, $10,000 more is charged for each 30 days. In all, once the IRS can tell the amount involved, the penalties for one failure are cut to that amount and any excess is refunded, so a $7,000 distribution left off Part III costs no more than $7,000.143,144,145 No penalty applies to a failure due to reasonable cause and not willful neglect, and a foreign law that forbids disclosing the information is not reasonable cause.146 The Form 3520 instructions add that reluctance by a foreign trustee or other fiduciary to give information, or a trust term that prevents its disclosure, is not reasonable cause either.147 A late or incomplete Part I, II, or III, or Form 3520-A, also keeps the IRS's time to assess the related tax open until 3 years after the information is filed: for the whole income tax return, or, if the failure had reasonable cause, only the items it relates to.148 Separately, if you underpay income tax because of a transaction involving an asset you had to report for that year under section 6048, on Form 3520 or 3520-A, and did not, the accuracy-related penalty on that part of the underpayment is 40%, not 20%, and it applies on that ground alone.149,150,151

Bona fide residents of the Commonwealth file their income tax return there, not with the IRS,11 but Form 3520 is an IRS return with its own due date, not tied to the income tax return's: the 15th day of the 4th month after your tax year ends.152 It goes to the IRS at Ogden, Utah, not to the Commonwealth's Division of Revenue and Taxation.153 The instructions move the date to June 15 for a citizen or resident who lives, and has a place of business, outside the United States and Puerto Rico, with a statement attached, and to October 15 with an extension of the income tax return.154,155 A resident of the Commonwealth appears to meet the June 15 condition, because the United States in a geographical sense is only the States and the District of Columbia,22 but the instructions do not say whether an extension the Commonwealth grants for its own return counts, so the cautious course for a resident who files no U.S. return is June 15 at the latest.
