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.
U.S. multinational groups with $850 million or more in consolidated revenue must file Form 8975 with one Schedule A per tax jurisdiction. This guide walks through the four-part threshold test, the Schedule A line items, the Pillar Two transitional safe harbor that now relies on CbCR data, and the five filing mistakes that most often trigger audits in the 2026 cycle.
U.S. multinationals with $850M+ in consolidated revenue file Form 8975 with Schedule A per jurisdiction. In 2026 the report also gates the OECD Pillar Two transitional safe harbor at a 17% simplified ETR — making CbC data accuracy a strategic, not clerical, priority.
Schedules K-2 and K-3 pulled even purely domestic partnerships and S-corps into international tax reporting starting in 2021. This guide explains the 2026 filing rules, the four-condition domestic filing exception, the January 15 partner notification and February 15 1-month K-3 request deadlines for calendar-year filers, the $250,000 small entity carve-out added in 2024, and the per-partner, per-month penalty math for non-compliance.
The Corporate Alternative Minimum Tax imposes a 15% levy on Adjusted Financial Statement Income for corporations averaging over $1 billion in AFSI. A practical guide to who qualifies, how AFSI is computed under section 56A, the FPMG $100M U.S. test, Form 4626 mechanics, and the interim simplified safe harbor.
Under OBBBA, Section 250 renames FDII to FDDEI, sets the deduction at 33.34%, eliminates the QBAI offset, and removes interest and R&E allocation — producing an effective 14% federal rate on qualifying foreign-derived income for U.S. C corporations filing Form 8993 in 2026.
A working guide to the FDII (now FDDEI) deduction on Form 8993 — which U.S. C corporations qualify, how the Section 250 math drops the effective federal rate to 13.125% on foreign-derived income, the taxable income limitation, documentation the IRS expects, and how OBBBA simplifies the calculation starting in 2026 by removing the QBAI step and expense allocations.
The IC-DISC is the only permanent federal tax incentive dedicated to U.S. exporters that is available to pass-through entities. It routes export commissions through a tax-exempt paper corporation and back out as qualified dividends, cutting the effective federal rate on export profits from roughly 40% to 23.8% for closely held manufacturers, distributors, software vendors, and engineering firms.
An IC-DISC is a paper-only U.S. C corporation authorized by IRC Sections 991–997 that lets closely-held manufacturers, distributors, and growers convert qualifying export profit from ordinary income rates (up to 37%) into qualified dividend rates (20–23.8%), with typical setups producing $50,000+ in annual federal tax savings on $5M of qualifying export sales after Section 199A's 2026 sunset widened the rate spread.
