Cross-border tax compliance, foreign income reporting, and US international tax obligations for individuals and corporations
FIRPTA requires US real estate buyers to withhold 15 percent of the gross sale price from foreign sellers and remit it on Form 8288 within 20 days of closing. This guide explains Section 1445, the $300,000 personal residence exemption, the 10 percent reduced rate, withholding certificates on Form 8288-B, and how buyers avoid personal liability with an Affidavit of Non-Foreign Status.
A side-by-side guide to Form 1116 (Foreign Tax Credit) and Form 2555 (Foreign Earned Income Exclusion) for expats and cross-border workers in 2026 — the $132,900 FEIE cap, the five-year revocation lock-in, the FTC stacking rule, and a worked example showing when each one actually saves money.
Form 8832 lets eligible entities — domestic LLCs and most foreign companies — elect to be taxed as a disregarded entity, partnership, or C corporation. This guide covers default classifications, the 60-month lockout, late-election relief under Rev. Proc. 2009-41, and how Form 8832 differs from Form 2553.
How non-willful US taxpayers use the IRS Streamlined Filing Compliance Procedures to catch up on FBAR, Form 8938, and three years of late returns—zero penalty under SFOP for taxpayers abroad, a one-time 5% miscellaneous offshore penalty under SDOP for domestic filers, plus what the non-willfulness certification must demonstrate.
Section 482 reaches any small multinational with intercompany transactions, and missing Forms 5472 carry $25,000 penalties each. A working guide to the arm's-length standard, the five transfer pricing methods, contemporaneous documentation, and how OECD Pillar Two affects US-headquartered groups in 2026.
US payers must collect a valid W-8BEN or W-8BEN-E from a foreign vendor before paying, or the IRS treats the payment as subject to 30% withholding plus Form 1042-S penalties. This guide walks through which form to use, how to claim treaty benefits, the three-year refresh cycle, FATCA classification, and the five documentation mistakes that turn routine vendor onboarding into an audit problem.
How the 10-digit Harmonized Tariff Schedule, Chapter 99 add-ons, and Section 301 layers assign legal duty liability to the importer of record—not the broker—and how a prior disclosure under 19 U.S.C. § 1592(c)(4) can cap penalties at interest if you find errors before CBP audits.
Foreign owners of US single-member LLCs must file Form 5472 by April 15, 2026, even with zero revenue. A capital contribution as small as $1 triggers the requirement, and a missed filing carries a $25,000 minimum penalty plus uncapped $25,000 continuation fees every 30 days after IRS notice.
Form 1042-S reports US-source FDAP income paid to foreign persons. US businesses act as withholding agents with personal liability — default 30% withholding, W-8 documentation rules, March 15 deadlines, and stiff per-form penalties. This guide covers W-8BEN versus W-8BEN-E, treaty rate reductions, the source-of-income rules, and common mistakes like sending Form 1099 to a foreign contractor.
A Section 962 election lets US individual owners of a controlled foreign corporation be taxed on GILTI/NCTI at corporate rates, cutting the effective US rate from up to 37% to roughly 12.6% in 2026. The OBBBA reduced the Section 250 deduction to 40%, eliminated the QBAI carve-out, and raised the indirect foreign tax credit cap from 80% to 90% — but PTEP rules can still trigger a second layer of US tax when earnings are eventually distributed.
PFICs (foreign mutual funds, UCITS ETFs) trigger Section 1291 tax for US investors — gains allocated across the holding period, taxed at top ordinary rates, plus compounded interest charges. This guide covers Form 8621, the QEF and mark-to-market elections, the $25k/$50k de minimis filing exception, and how to escape the trap.
Form 5471 carries automatic $10,000-per-corporation initial penalties capped at $60,000 per year for U.S. persons who own, control, or serve as officers of foreign corporations. Covers the five filing categories, modular schedules, GILTI's rename to NCTI for tax years beginning after December 31, 2025, and the Streamlined and Delinquent Submission routes back into compliance.
