Cross-border tax compliance, foreign income reporting, and US international tax obligations for individuals and corporations
Nonresident aliens who own U.S. real estate, U.S. corporate stock, or other situs property get only a $60,000 estate tax exemption — not the $13.99 million citizens enjoy in 2026 — and pay up to 40% on the excess. A working guide to Form 706-NA, FIRPTA withholding, treaty relief via Form 8833, transfer certificates, and the blocker-corporation structures that actually work.
Form 8858 reports foreign disregarded entities and foreign branches on a U.S. return, and missing one carries a $10,000 penalty per entity per year that can snowball to $50,000 after IRS notice. This guide covers who must file, Schedules C through M, Section 987 currency calculations, the Schedule K-2/K-3 box 11 connection for Category 6 filers, and the four paths back into compliance.
Section 1446(f) requires buyers of partnership interests to withhold 10% of the amount realized when a foreign partner sells and remit it to the IRS within 20 days on Form 8288. This guide walks through the six exceptions, the certifications that must be in hand before closing, and the bookkeeping records that defend the position under audit.
Section 245A grants a 100% dividends-received deduction on qualifying foreign dividends to U.S. C corporations, but only when the 365-day holding period, hybrid dividend, extraordinary disposition, and PTEP ordering rules all hold. This guide explains how the participation exemption coordinates with GILTI and Subpart F, the traps that disqualify the deduction, and the bookkeeping that keeps it defensible on audit.
Section 367 overrides corporate non-recognition rules the moment U.S. property crosses into a foreign corporation, forcing immediate gain on outbound asset and IP transfers. This guide explains Sections 367(a), (b), (d), and (e), the GRA and Form 8838 deferral path, the 10% Form 926 penalty, the TCJA expansion to goodwill and workforce in place, and the 2024 final regulations on IP repatriation.
A practical walkthrough of IRC Section 7701(b) for globally mobile founders — the 31-day floor, the weighted three-year 183-day formula, exempt-individual rules, the closer connection exception (Form 8840), and treaty tie-breakers (Form 8833) — with a worked example showing how 130 U.S. days in 2026 can trigger worldwide taxation.
Section 1248 recharacterizes part of a U.S. shareholder's gain on the sale of CFC stock as a dividend, capped by the corporation's earnings and profits and reduced by PTEP from GILTI and Subpart F inclusions. This guide explains who is affected, how the lookback works, why corporate sellers can prefer the recharacterization for Section 245A, and how to build a defensible work paper.
Form 6166 is the IRS-issued certificate of U.S. tax residency that unlocks reduced foreign withholding under bilateral tax treaties. Apply with Form 8802 — $85 for individuals, $185 for entities — and one filing covers unlimited countries and certificates, often saving five or six figures per cross-border contract.
Form 6166 is the IRS letter that lets U.S. taxpayers claim treaty rates on foreign royalties, dividends, and services. This guide walks through the Form 8802 application, eligibility rules, common rejection traps, and the timing required to get withholding right at the source.
Section 877A treats covered expatriates as if they sold every asset the day before leaving the United States. For 2026 the net-tax threshold is $211,000, the net-worth test sits at $2 million, and the gain exclusion is $910,000 — here is how Form 8854 decides whether you pay.
Form 8865 is the U.S. information return for foreign partnership interests, with $10,000 per-partnership per-year penalties for non-filing. This guide breaks down the four filer categories under Sections 6038, 6038B, and 6046A, the constructive ownership rules that catch most surprise penalties, and the schedules each category must include.
Form 8865 makes U.S. persons report controlled foreign partnerships, property contributions, and 10-percentage-point interest changes. Missing it triggers $10,000 per partnership per year, plus a 10% foreign tax credit haircut and stacking 30-day penalties up to $50,000.
