Tax and Estate Planning for Non-Citizens in the United States
A Guide for Financial Advisors, Tax Advisors and Estate Planners
The book treats the taxation and estate planning of individuals who live in the United States without U.S. citizenship, from the years before arrival to the return to the home country, and of their families as clients and as heirs.
By Caroline E. Ashford, PhD, JD · Clarison Press · In English

In brief.
- Income tax residence and transfer-tax domicile are separate tests. The book treats both in full, visa category by visa category, and the four combinations they produce.
- The estate and gift tax conventions are treated as the rule. The German, French and British conventions give a national of those countries who moves to the United States a grace period during which the convention treats the individual as domiciled in the home country.
- The planning before arrival, the reporting that begins in the first resident year, and the foreign companies, real property, pensions, insurance and trusts that a new resident holds abroad.
- The spouse who is not a U.S. citizen: the marital deduction denied by statute, the qualified domestic trust, the treaty marital deductions, and naturalization as the alternative.
- The resident alien as heir and beneficiary, Forms 3520 and 3520-A, gifts and bequests from covered expatriates under section 2801, and the departure from the United States.
Readers
The book is written for financial advisors, tax advisors and estate planners whose clients hold a green card or a nonimmigrant visa, and for the advisors of the families of those clients, whether the family members are clients themselves or heirs. It assumes a reader who knows the U.S. rules for citizens and needs the rules that change when the client is not one.
Where the client comes from Germany, France, Switzerland, Italy or the United Kingdom, the book gives the position of that country in short comparative sections. It reads the estate, gift and income tax conventions as the rule and the statutory regime as the exception.
What the book covers
Parts 2 and 3 settle status. They set out the green card test and the substantial presence test with its exceptions, the effect of each visa category on those tests, the domicile of visa holders and green card holders for the estate and gift tax and between the states, the treaty grace periods for new U.S. domiciliaries, and the compliance of the arrival and departure years. They then address the planning to be completed before the move and the worldwide income, estate and gift tax position that begins with residence.
Part 4 treats what the new resident holds abroad: a foreign company under the controlled foreign corporation rules, foreign real property and other foreign-situs assets taxed in two countries, the residency certification on Forms 8802 and 6166 for treaty relief abroad, the shares of a European family business received by a successor resident in the United States, foreign pensions and life insurance, and foreign and irrevocable trusts.
Parts 5 to 8 cover equity compensation and secondments, the spouse who is not a citizen and the choice between the green card and naturalization, the resident alien as heir of a foreign estate and as beneficiary of U.S. accounts and trusts, and the client who gives up the green card and returns home.
The book stands alone. Like each book of the series, it opens with a foundations chapter on status, situs, the treaties and the reporting forms, adapted to its readers, and gives a working summary wherever its readers must apply a rule that another book of the series treats in full.
