Title 26 › Subtitle A — Income Taxes › CHAPTER 1 — NORMAL TAXES AND SURTAXES › Subchapter N — Tax Based on Income From Sources Within or Without the United States › PART II — NONRESIDENT ALIENS AND FOREIGN CORPORATIONS › Subpart A — Nonresident Alien Individuals › § 877A
If a U.S. citizen or long-term green-card holder gives up their U.S. status, the law treats all their property as if it was sold the day before they leave. Any gain from that notional sale is taxable for that year, and losses count only if other tax rules allow (the usual wash-sale rule does not apply). You can exclude up to $600,000 of gain from tax (that $600,000 is adjusted for inflation for years after 2008). You may choose to delay paying the tax on some property until you actually sell it, but only if you give the IRS adequate security (for example, an accepted bond or other approved guarantee), you make an irrevocable waiver of treaty rights that would block collection, and the election applies only to the specific property chosen and cannot be changed. Interest rules still apply and payment cannot be delayed past certain deadlines, including the year of death. Some kinds of assets follow special rules instead of the general sale treatment. Deferred compensation and many retirement or tax-deferred accounts (like most IRAs, 529 plans, 529A, Coverdell, HSAs, and Archer MSAs) are treated as distributed the day before expatriation. For eligible deferred compensation, the payer must withhold 30 percent when making taxable payments. Nongrantor trusts must withhold 30 percent on taxable distributions to the expatriate, and the trust recognizes gain if property distributed is worth more than its basis. Short one-line definitions you should know: covered expatriate = a person who meets the tests that make the tax rules apply; expatriate = someone who gives up U.S. citizenship or who is a long-term resident who stops being a lawful permanent resident; expatriation date = the date citizenship is relinquished or the green card ends; early distribution tax = extra tax penalties for early withdrawals under certain codes. The IRS Secretary will issue rules to carry out these rules.
