We Know the Tax Side of Your Business Abroad.

You Need Clarity on Foreign Entity Rules

You built a successful entity abroad, but U.S. cross-border reporting rules are difficult to decipher.


Form 5471 schedules require a tax law background just to follow the basic reporting rules.

You Worry Past Filings Are Missing Something

You know an unfiled form carries a $10,000 baseline penalty, and that exposure creates constant concern.


You filed on your own or with a general accountant and no longer trust it was complete.

You Face Shifting GILTI and Calculation Rules

Transitioning GILTI to Net CFC Tested Income adds complex new math, leaving your tax liability unclear.


You can’t tell when retained earnings or dividends become U.S.-taxable income.

You Want Tax Answers Before You Decide

A pay change, a buyout offer, or a restructuring each carries U.S. tax you cannot weigh alone.


The tax answer often arrives at filing time, months after the decision it should have shaped.

Foreign Business Tax Resources

Greenback maintains a comprehensive library of guides covering nearly every tax topic a U.S. owner of a foreign business faces. Here are the resources our clients reach for most.

What Form 5471 Requires and Who Must File It

If you own part of a foreign corporation, Form 5471 and the Controlled Foreign Corporation (CFC) rules likely apply, and your ownership percentage sets your filing category and schedules. Our Form 5471 guide breaks down the categories, our CFC guide explains when a company counts as one, and our foreign business reporting guide covers what you file each year.

How NCTI Replaced GILTI for Your Foreign Company

The 2025 tax law renamed GILTI to Net CFC Tested Income (NCTI) for tax years beginning after December 31, 2025. It removed the 10% deemed return on tangible assets (QBAI) and cut the Section 250 deduction from 50% to 40%, so more foreign profit is taxable even if you leave it in the company. Our guide to Net CFC Tested Income (NCTI) breaks down the new math.

How the Foreign Tax Credit Offsets U.S. Tax

When your corporation pays tax abroad, the U.S. may still tax the same income, and the Foreign Tax Credit is how you avoid paying twice. Our guide to the Foreign Tax Credit explains how it works, and our FEIE vs. FTC guide helps you see which strategy fits.

How Your Business Structure Changes Your U.S. Tax

Whether the IRS treats your company as a corporation, partnership, or disregarded entity drives which forms you file and how much you owe. Our Form 8832 guide covers the entity classification election, our Form 8858 guide covers foreign disregarded entities, and our Form 5471 vs. 5472 guide clarifies which form applies to your structure.
