Spring Semester 2017

Chapter One

Relevance of this United States international income taxation course

Fundamental income tax considerations concern:

                1)  Inbound (into U.S.) investment and business activities

                2)  Outbound (from U.S.) investment and business activities


United States  international taxation

U.S. income taxation of cross-border/transnational transactions;

                i.e., national, not international law.

Two parallel U.S. income taxation systems:

                1) U.S. Internal Revenue Code rules, &

                2) a U.S. bilateral income tax treaty

                 (see the 2016 U.S. Model Income Tax Treaty & the 2014 OECD Model Tax Treaty)

Cf., foreign country income taxation on income derived in country or by its taxpayers.



Process of coming into the United States                p.2

Immigration – changing individual or entity U.S. tax status

Passive investment in the U.S.

                - securities (stocks & bonds)

                - real estate

Cf., active conduct of a “trade or business” in the United States (i.e.,  “ETBUS”).


IRC §61 - Income “from whatever source derived”

Basic U.S. tax structure (worldwide income):

1)  Tax rates: Individual – 39.6%;  Corp. – 35% 

2)  Capital gain rate preference – for individuals (20%), but not for corporations.

3)  Corporate income taxation – classical system of taxation to corporation and its shareholders.

4)   Special Code §199 deduction to encourage U.S. based manufacturing.

5)   Tax common law concerns: economic substance

       (§ 7701(o));  business-purpose; substance over                   form, etc.

How Allocate the Burdens of U.S. Income Taxation?

Taxation of both (1) labor income & (2) capital income.

Tax base theory:            p.12

   - Cost analysis - cost to the government

   - Benefit analysis - what benefits are received by the particular taxpayer?

   - Taxpayer’s ability to pay?

Other jurisdictional approaches:               p.13-14

What “nexus” for asserting income tax liability?

1.  Political allegiance (i.e., passport status);  cf., economic allegiance.

2.  Residence (for how long?)

3.  “Domicile” or permanent residence

4.  Physical location (i.e., situs) of the owner’s wealth/property; cf., tangible & intangible property

Are these concepts consistent with “international law”?


Considering the reach of cross border taxation  p.16

What impact of "customary international law” & exercise of extraterritorial taxing jurisdiction?

How mitigate international double taxation?  (1) Exemption or (2) tax credit.  Cf., tax treaties.

                Use a divided taxation approach based on the type of income?

International tax collection & enforcement problems –  p.19;  no cross-border tax liability enforcement occurs (the “revenue rule”);  why?

                Therefore, tax collection at source on passive, investment income is necessary. 

International Tax Neutrality Concepts     p.20

Capital export neutrality - same income tax rate is imposed regardless of the location of U.S. taxpayer’s income (but a possible higher foreign tax cost arises if the foreign tax is higher than the US tax rate;  refund of this tax?).

Capital import neutrality - all firms in the same market are subject to the same rate of income tax.  Only the country where the investment is located imposes an income tax.  Implemented through a territorial or exemption approach.

Should all foreign income be exempted from U.S. income tax for U.S. taxpayers?

Limiting international economic double taxation

1)  territorial/exemption system (exempting

foreign income); note current U.S. income tax proposals.

2) (a) foreign tax credit system – the source country has the priority to tax; is source country tax at a higher or lower rate than home country tax?  or,  (b) a deduction for the foreign tax paid.

3)  an agreed allocation of the income tax

jurisdiction and liability - e.g.,   lower withholding rates are imposed at source – a bilateral (rather than a unilateral) response.


“Deferral” Principle of U.S. Outbound Taxation      p.24

1) Taxation of foreign “branch” income - §61

(when the branch has no separate legal identity)

2) Foreign “subsidiary” income – respect the foreign

entity as having a separate (foreign) legal status for

U.S. income tax purposes. But: possible U.S. income

tax applicability of:  (1) “Subpart F” (in Subchapter

N) for limiting U.S. income tax deferral (i.e., current

inclusion required),  or (2) PFIC provisions.                                                                          

                                                                   Next slide.

How eliminate the U.S. tax deferral opportunity?   p.26

1)  Current recognition – Subpart F provisions – type of income causes current income.

2)  Interest charge on the deferred tax amount – PFIC provisions; §1291, et. seq.

3)  PFIC - “mark-to-market” of accrued gain – i.e., include unrealized gain in current tax base.

Consider transfer pricing opportunities for shifting income offshore in related party transactions. §482 (p.32).

Domestic Effects of Foreign Investment      p.26

Does U.S. international tax policy encourage foreign (not U.S.) investment which enables current U.S. based jobs to move offshore?

Is foreign investment (1) a substitute for domestic investment, or (2) an increase in the corporate footprint?   I.e., does foreign investment reduce domestic investment?

Consider the “runaway plant” syndrome.

Collateral Effects in Tax Policy                           p.31

Use U.S. cross-border tax policy to achieve

economic or political objectives (rather than

merely “raising revenue”)?  

Tax penalties/negative tax expenditures.

E.g., (1) anti-boycott provisions re limit of foreign

tax credit;  (2) no deduction for foreign bribes;

(3) no FTC when tax on income is derived in a

hostile country.

Potential “Double Non-Taxation”                     p.33

Cross border tax “arbitrage” –

What is “arbitrage”?   “Double benefits”?

Objective:   avoidance of taxation in both

jurisdictions  (i.e., “double non-taxation”) because

of differing residence or sourcing rules.

Achieved through: (1) income characterization

rules,  & (2) use of “hybrid entities” (e.g.,

a corporation in one jurisdiction but a flow-

through entity in the other jurisdiction).

What Limitations on Cross Border Arbitrage?        p.34

Specific limitation statutes;  e.g., § 1503(d) re dual consolidated loss rules.  Otherwise achieved by different corporate “residency” definitions.

Cf., §7701(o) re “economic substance” doctrine.

Tax shelter limitations & “reportable transactions.”  §6111.

FIN 48 – identify potential cost of uncertain tax positions and create reserve for GAAP purposes.

Uncertain tax position reporting to be made to IRS on its UTP corporate tax form.

Basics - Foreign Persons  p.36
Active U.S. Business Income

U.S. trade or business income - p.36

                Code §§871(b) & 882 – net income tax (39.6/35% rates) imposed on this net income.

Issue concerning what is a “trade or business” in the U.S. – “regular & continuous activities.”

See §864(b).  Are personal services included?

What income is "effectively connected” (ECI) with that U.S. trade or business (USTB)?  I.e., how strong is the tax inclusion “magnet,” i.e., does a “force of attraction” rule apply?

Tax on U.S. Profits of a Foreign Corporation          p.37

A §884 “branch profits” tax is applicable on the after-tax profits of the foreign corporation realizing net profits in the U.S.  

What is the purpose/timing for this tax imposition?

Is this tax imposed in lieu of a withholding tax on a dividend distribution from a U.S. subsidiary owned by a foreign corporation (or an individual) since no corporate dividend is actually distributed by a branch?

U.S. Investment Income of Foreign Persons           p.38

Investment income taxed - §§871(a) & 881(a).

Gross withholding “at source” is applicable.

Exemption from income tax liability available for:

                (1) portfolio interest; (2) bank interest;

                (3) capital gains on stock & securities

No U.S. income tax exemption for (1) real estate

income (including sales) (§897), including stock of

real estate company (& §1445 withholding); or,

(2) contingent royalties (§871(a)(1)(D) & §881(a)(4))

(& §1441 & 1442 withholding).

U.S. Persons - Taxed on Worldwide Income?     p.39

1)  Taxation on worldwide income.  Code §61(a). 

Why worldwide income taxation here?

2)  Relief from double taxation – §§901 & 902.

                -direct credit for foreign tax paid; and

                -indirect (or “deemed paid”) credit (for 10% or greater foreign sub. dividends by U.S. corp.).

3)  Possible deferral of U.S. income tax (p.40) –

subject to: Subpart F regime;  PFIC rules.

4)  Possible exemption from U.S income tax on certain foreign earned income tax - §911 (p.40).

U.S. Citizens                     p.41
Worldwide Taxation Applies

Individuals  - Citizens of the United States

                Cook v. Tait,  p.41 - issue concerns the U.S. power to tax a foreign resident/U.S. citizen on that person’s foreign sourced rental income:

                (1) a U.S. constitutional claim?

                (2) an international law claim (violation of principles of customary international law)?

U.S. income tax jurisdiction is based on U.S. citizenship status. 

“Resident” Aliens?    p.43
“Bright Line” Tests

§7701(b) definitional (objective) provisions for

determining resident alien status:

1) “Green card” test,  or

2) "Substantial presence" test - current 31 days & 122 day test (3 year) – how computed?

3) “Closer connection” current year exception (p.45) - §7701(b)(3)(B);  (a) less than 183 days in U.S.,  & (b) tax home in the other country. See §162(a)(2) re “tax home” concept.

    “Closer connection”, i.e., significant contacts.


Resident Aliens         p.44
§7701(b) Exceptions

Excluded days/status for computing “substantial presence” test:

-  Commuters (“fast lanes” across borders).

-  Crew members of foreign vessel.

- Travelers in transit through the U.S.

- Diplomats & international org. employees

- Certain professional athletes

- Medical condition arising while in U.S. (not if coming to U.S. for medical treatment).


Result of Resident Alien
Status?                    P.46

First year election - §7701(b)(4).

Why?  Obtain availability of deductions (e.g., expropriation losses incurred in the former country - deemed occurring as of time of one’s departure from that country).

Cf., deductions for nonresident aliens – only for those expenses attributable to related U.S. business activities.

Problem 2: Substantial presence test?             p.47

i)             §7701(b)(3)(A)(i) - physically present in the U.S. for at least 31 days in year 3.

ii) §7701(b)(3)(A)(ii) - 193 days of deemed physical presence

                Year three      120 days

                Year two           50 days (1/3 of 150 days test)

                Year one                        23 days (1/6th of 138 days)

                            193                          continued


Wolfgang, cont.
re:  U.S. taxpayer status

iii)           Question re qualification for closer-connection exception - §7701(b)(3)(B).

                §7701(b)(3)(B)(i) - physically present in U.S. for less than 183 days in year three.

                §7701(b)(3)(B)(ii) – is the “tax home” in a foreign country?  See § 911(d)(3).

                §7701(b)(3)(B)(ii) – the "closer connection" test.



Problem 5: Anticipated immigration into U.S. p.48

“Landed basis,”  i.e., no “mark-to-market” tax basis regime (therefore, no “landed basis”) when U.S. status commences.

Therefore: i) Sell gain assets before U.S. status (how accomplished?),  and,

                ii)  Retain loss assets (for sale when individual is later subject to U.S. worldwide taxation).

How prove U.S. income tax basis for the prior foreign acquired assets when no “landed basis” system applies?

Former U.S. Citizens and Residents - prior cases

Furstenberg case: U.S. citizen, married an Austrian

prince and lost U.S. citizenship.

Was the “principal purpose” of her relocation the 

loss of U.S. citizenship for tax purposes?

Principal purpose: of “first importance.”

Held not a tax avoidance purpose.  She was a tax

neophyte.  Cf., Max Kronenberg case – arrival in

Switzerland and immediate termination of  U.S.

citizenship & then business stock sale.


Tax expatriate provision -
§877  (to 6-17-2008)    p.49

An individual is conclusively presumed to have a principal purpose of U.S. tax avoidance for the loss of U.S. citizenship if:

1)  annual average net income tax for five years

prior to loss of U.S. citizenship is more than $124,000 (as indexed),  or

2)  individual's net worth is at least $2,000,000.

Tax on U.S. income for ten years after expatriation, i.e. ten year long-arm statute.  

Exceptions - next slide.


Code §877, continued
Exceptions                  p.51

Exceptions under some circumstances:

1) Citizen of another country at birth & no

substantial contacts with the U.S., or

2) U.S. citizen at birth but having foreign parents and less than 30 days in U.S. for each of last ten years & terminate before age 18 1/2.

Similar §877 treatment for “long-term” U.S.

residents - i.e., individual spent at least 8 of the

prior 15 years in the U.S.  How to avoid

this rule?



U.S. Income Treatment of U.S.Tax Expatriates? P.52

Special income sourcing rules - §877(d)(1) –

gains from sale of property as U.S. source.

Special sourcing rule for U.S. stock gains.

Nonrecognition provisions are not applicable

when purported tas free exchange occurs

for foreign property.


Information reporting requirements apply.

§877(g) – possible worldwide taxation where 30

days+ presence by expatriate in U.S.

 Code §877, continued

Constitutionality of §877?

   cf., the challenge in the Di Portanova case, p.52

   - invalid exercise of personal jurisdiction

                   but, is this source based taxation?

                - denial of due process?

      reasonable differentiations permitted?

Real answer?  Mark-to-market at time of

expatriation; but, consider the “human rights”

issue (i.e., denial of “freedom of movement”)?

“Mark-to-Market” Rules Section 877A              p.53

Expatriations occurring after 6-17-2008.

A “mark-to-market” regime replaces the 10-year

“alternative tax” on U.S. source income.

A “covered expatriate” is deemed to sell all

worldwide property for its FMV on the day

before expatriation.

Taxed on net gains above a $600,000 exemption

amount, as indexed ($699,000 for 2017).

Uncertain how the tax character is

determined/allocated among assets.

Mark-to-Market Rules, continued

“Covered expatriate” – defined by same average

annual income tax ($162,000 for 2017) or net

worth ($2 million) at date of his expatriation.

Exceptions for dual citizens at birth (if not

meeting substantial presence test).

Limitation of the “landed basis” rule – solely for

purposes of the “exit tax” - basis is value as of

the date becoming a resident (& an election out

of this rule is possible; e.g., when loss property is

held at residence date?).  §877A(h)(2).

Mark-to-Market Rules, continued                   p.55

Covered expatriate can elect to defer payment of

tax until (1) actual sale or exchange, (2) failure

of adequate security, or (3) death. §877A(b).

Must provide “adequate security” & pay interest

on the deferred income tax.

Must waive U.S. tax treaty benefits. §877A(b)(5).

If death occurs before all deferred tax is paid,

then this tax is due on the final U.S. income tax

return (&, e.g., no tax basis step-up occurs).

Mark-to-Market Rules, continued;  exceptions

Exceptions to the “mark-to-market” rules:

  1)  Deferred compensation items.

  2)  Interests in non-grantor trusts, etc.

Is estate tax (not income tax) avoidance the

biggest expatriation tax issue?  §2107.

And, see Code §2801 – a new “succession tax” –

Gifts & bequests to U.S. persons from a

“covered expatriate” are taxed to the recipient at

 the then highest gift or estate tax rate.


Documenting Citizenship Termination                p.55

U.S. citizenship relinquishment when:

1) Renouncing before a U.S. consular official, or

2) A statement of voluntary relinquishment (and

then approved by U.S. State Dept.), or

3) Issuance of “certificate of loss of nationality”

4) U.S. court cancels a naturalized citizen’s certificate of naturalization.

See §6039G re information to be provided to IRS concerning foreign location, etc.  What if non-compliance with reporting?  P.56


Expatriation Problem -
§877 vs. §877A           p.56

Hacker, expatriate, destined for Monaco.  

Stock gain on his computer company & he wants

to avoid U.S. capital gains tax.

Not possible to avoid §877A exposure & no §877A exceptions are available.

Prior advice: live ten years and do not sell stock.

Now – an income realization event for U.S.

income.  Net capital gain of 100 mil. less basis

and less exclusion amount (§877A(a)(3)).

U.S. Corporations         p.56
Identifying U.S. Tax Status

Definition:   Code §7701(a)(3) & (4) & (5).

“Corporation” includes associations, joint-stock

companies and insurance companies.

What is a “corporation” (for U.S. tax)?

“Choice of entity” or “check the box” rules.

Foreign jurisdictional tests - place of  "mind and

management" of the corporate entity to establish

residency status of a corporation.

Cf., 2005 JCT Options paper test – (noted at p. 57) -

use the primary place of management and control?

Partnerships - conduit entities                             p.57

U.S. partnerships (& U.S. LLCs, if a partnership) –

flow through income tax treatment for both the U.S.

and the foreign partners.

Foreign partnership & foreign income - no deferral

for U.S. partners - since needing foreign corporate

status to avoid conduit, transparent treatment; 

includes LLC treated as partnership (for U.S. tax).

Planning for U.S. person: Use a foreign “blocker”

corp. to hold the foreign partnership interest?

The Entity Characterization Process                            p.59

How determine entity characterization?

“Check-the-box” rules, but see listing of certain

foreign entities as “per-se” corporations (as

categorized for U.S. tax purposes).  See Reg.

§1.7701-2(b), including 2(b)(8) listing.

Other entities are “eligible entities” - which can

elect - ordinarily choosing conduit status. 

Consider impact of the “default” rule on status.

Election problems with a foreign conduit entity?

JCT Options Paper (2005) reconsider “check the

box” for foreign entities & 2010 Obama proposal?


Trusts & Estates          p.60
How/where created? 

§7701(a)(30)(E) - re differentiating between a U.S. trust and a foreign trust:

                - U.S. court test

                - U.S. fiduciaries & control test

§7701(a)(31)(A) – estate status

                definition of a foreign estate as an estate not subject to taxation on its worldwide income.  Otherwise, a U.S. estate.

                Where are the assets? Where is the primary estate administration occurring?  Relevance of an ancillary administration?


Problem - U.S. Cleanliness and Camclean Foreign Sub.       P.61

Issues in these problems:           

A) Right of the U.S. to tax under international law?

B) What basis for the exercise of U.S. tax jurisdiction (i.e., by the IRS)?

C) Taxability in the United States?

D) If taxability, then how taxed:  (i) gross withholding basis, or (ii) net income basis?


The Role of International Bilateral Tax Treaties  p.62

§894(a)(1) – apply “due regard” for treaties.

Purposes of bilateral U.S. income tax treaties:

1)  to define “residence” status.

2)  provide income tax rate reductions – avoiding double taxation (shift income status to the residence jurisdiction?)

3)  cooperation between taxing authorities and to enable the exchange of tax information so as to assure tax compliance in both countries.


Other Relevant Tax International Agreements

1)  Tax Information Exchange Agreements (TIEA).

2)  FCN Treaties – Friendship, Commerce and Navigation Treaties (not tax, but having wide application).

3)  Memoranda of Understanding (MOUs) on specific issues:  Note IRS Announcements 2006-4, 2006-5 & 2006-6 (Japan, Canada and Mexico).

4)   Mutual Legal Assistance Treaty (MLAT) – criminal matters, including tax crimes.

5)   Totalization agreement – social security treaty.

Model Bilateral Income Tax Treaties                p.63

1)  U.S. Model (2016; cf., 2006 model, but impacted by subsequent bilateral U.S. tax treaties?)

2)  OECD Model (2014) – dynamic, i.e., under a regular revision process (see U.S. Technical Explanation notation re OECD Model).

3)  U.N. Model – developing countries perspective is included in its provisions.

Possible multilateral income tax treaty?  Perhaps on a regional basis?   E.g., similar to NAFTA?

Cf., Nordic tax treaty

Tax Treaty Making & Ratification Process    p.64

1)         Negotiation by U.S. Treasury Department representatives (& IRS) (not U.S. State Dept.).

2)            “Advice & consent” by U.S. Senate, after review by Senate Foreign Relations Committee (Chair Bob Corker), not Senate Finance Committee.

3)            No U.S. House of Representatives (e.g. Ways & Means Committee) participation in the tax treaty process. Therefore, tax treaty can only reduce taxes.  Note:  Origination clause.

4)            Effective upon an exchange of instruments of ratification.  Cf., Vienna Convention on Treaties re interpretation of treaties (i.e., intl. law).

Treatment of Income Items under Income Tax Treaties

Business income  - tax if a “P.E.” exists;  cf.,  sales income but no P.E. in a foreign jurisdiction.

P.E. status occurs if “dependent” agent exists. 

Personal services income - 183 day rule – if income is treated as not received from the U.S.  fixed base, i.e., the “commercial traveler” exemption is applied at source.

Nonbusiness income - reduction of the rate of tax & tax withholding at source. Capital gains - tax immunity at source, except for real estate.

Other income - tax at residence.

Certain Treatment under Income Tax Treaties

Taxes covered – p. 67 – “income taxes”(& taxes imposed by sub-national governments in the other country?)

 - cf., no treaty limit on state income taxes in U.S.   Cf., California “unitary taxation.”

Resident status defined (p. 67) – “tie-breaker” rules are applicable.

“Savings clause” applies for U.S. taxpayers,  so as

to cause worldwide taxation.  §1(4).  P.68.

Tax expatriation provision is included. §1(4).
