US International Corporate Tax
What does it cover?
A comprehensive overview of the US tax rules affecting multinational groups, from the federal corporate tax system to how the US taxes cross-border investment.
Who should attend?
Tax professionals who are new to US international tax, perhaps working in a group with a US parent or US operations, or advising clients who deal with the US.
Why choose this course?
Places are limited to 20, so you can ask questions and discuss the issues you meet in your own role. Three days in person suits busy professionals, including those travelling to the venue.
What's included in the fee?
Tuition built around worked examples, full course documentation and a trial of selected online materials, with refreshments and lunch across the three days.

What you'll gain from the course
Speak the language
Sometimes it seems like US colleagues and advisers are speaking a foreign language, full of terms like Subpart F, E&P and FDAP. Narelle breaks down the jargon with plenty of worked examples, so you can join US tax conversations with confidence.
Get more from your US advisers
Three days won't turn you into a US tax specialist, and the course doesn't pretend it will. It gives you the grounding to brief your advisers clearly, ask sharper questions, and judge when you need specialist advice.
Spot the issues early
By increasing your knowledge of how the US tax system operates, you can spot potential issues early. In a US-headed group, you'll understand what your US colleagues are dealing with, making you a more effective tax adviser in your own region. In a group with US operations, you'll know the US questions to ask before decisions are made, avoiding costly mistakes and recognising planning opportunities.
Learn alongside your peers
Participants have ranged from tax managers to tax directors, working in US-parented groups, UK and Irish headed multinationals with US operations, professional services firms, a pension fund and tax authorities. Some tax teams book together, with colleagues attending from across Europe. With numbers capped at 20 and three days in person, there is time to share experiences and compare approaches with people dealing with the same questions.
How you will learn
Taught by Narelle MacKenzie, lecturer at San Diego State University
Narelle MacKenzie is a well-known international tax advisor based in San Diego, with over 30 years of experience in international tax. Her career spans public accounting and industry, including seven years as an International Tax Director with PwC and Tax Director at Goodrich Corporation (a Fortune 500 company). She now runs her own international tax consulting practice, advising accountants, attorneys and in-house tax departments on cross-border planning and compliance.
Narelle began her career in Australian tax, first encountering the US system while working in-house for a multinational group. She then moved to California, and has worked in US international tax for nearly three decades. Her experience covers cross-border work in more than 20 countries, including supply chain projects, new manufacturing facilities and secondment arrangements. Having sat on both sides of those conversations, she knows what US tax teams need from their advisers or colleagues elsewhere, and what they need to understand in return.
Narelle has lectured at San Diego State University since 2007, teaching graduate classes in US international tax and multi-jurisdictional tax. She is an award-winning speaker, a Past President of the San Diego chapter of CalCPA, and holds CPA qualifications in both Australia and California alongside the IRS Enrolled Agent credential.

"This course is very close to my heart. I feel very passionate about US international tax and ensuring that others enjoy learning the material.
We start with the basics of the US tax system, because the international rules are an overlay on top. Then we cover the inbound rules, which are becoming more and more relevant with the One Big Beautiful Bill Act and its incentives to manufacture and operate in the United States. On the third day, we cover outbound taxation for US multinationals investing overseas.
If you're advising on investment into the US, this course is great for identifying issues that may impact your business or your clients. And if you work for a US multinational, you'll understand why your US colleagues ask the questions they do, and be able to help with what they need."

Frequently asked questions
Do I need any US tax knowledge before attending?
No. The Introduction to US International Corporate Tax course assumes no prior knowledge of US tax. The course begins with the structure of the US tax system and the federal corporate tax rules, before moving on to the international rules that build on them. Participants who already have some US tax knowledge also attend, to fill gaps and put structure around what they have picked up in their roles.
Can I attend the course online?
No, the Introduction to US International Corporate Tax course is an in-person course, held in London, United Kingdom and Dublin, Ireland. The teaching is built around discussion and worked exercises in a small group, which is what makes the course work, so there is no online or hybrid option. If your team would prefer online delivery, please contact us to discuss bespoke US tax training with Narelle MacKenzie.
Can I attend for one or two days rather than all three?
The Introduction to US International Corporate Tax course is designed as a complete three-day programme. Each day builds on the last, so attending in full is how you get the value from it. Bookings are for the full course. If three consecutive days are difficult in the current dates, the course runs each year in London and Dublin, and a later sitting may suit you better.
Is this course preparation for the ADIT US Tax exam?
The Introduction to US International Corporate Tax course is a practical three-day course, using real-world scenarios to show how the US tax rules apply in practice. There is overlap between the topics covered and the ADIT Module 2.10 syllabus, but it is not an exam preparation course. If you are looking to study US tax for the ADIT qualification, ExtraTax Training offers a dedicated online course for the ADIT US Tax module.
