Questions to Ask a Cross-Border Tax Professional Before You Act

The responsible, practical close to this entire topic — what to actually ask before you rely on anyone's advice.

Questions to ask a cross-border tax professional before you act are, in a real sense, the whole point of every other guide on this site. Everything covered elsewhere here — the avoidance-vs-evasion line, tax treaties, territorial versus worldwide taxation, Act 60, FEIE, foreign account reporting, and jurisdiction comparisons — exists to make you a better-informed participant in a conversation with a licensed professional, not to replace that conversation. This guide is the practical close: what that conversation should actually cover, and how to tell whether the person you're talking to is genuinely qualified for a cross-border situation specifically.

Why "a tax professional" isn't automatically "a cross-border tax professional"

Domestic tax preparation and cross-border tax planning are related but genuinely different skill sets. A preparer who is excellent at domestic returns may have limited experience with foreign account reporting, treaty analysis, or programs like Act 60, simply because most of their practice doesn't touch those areas. Before getting into specific questions, it's worth directly confirming cross-border experience: how many clients with a similar cross-border situation have they actually worked with, and can they speak specifically to the countries involved in your situation.

Questions about your actual residency situation

Based on my actual facts — not a general description — do I currently qualify, or would I qualify, as a tax resident of the destination country?
What specific documentation would I need to establish and later prove that residency?
Does becoming a resident there end my tax obligations in my current country, or does something like citizenship-based taxation mean it doesn't?

Questions about treaties and double taxation

Does a tax treaty currently exist between my home country and the destination country?
What does that specific treaty say about the categories of income relevant to my situation?
Are there "saving clause" or similar provisions that preserve my home country's right to tax me regardless of the treaty?

Questions about reporting obligations specifically

This section deserves its own weight, because our guide on foreign account reporting obligations covers why this is arguably the highest-stakes part of the entire topic.

What foreign account or asset disclosure requirements apply to my specific situation, and what are the current thresholds?
Am I currently missing any past filings, based on my history, and if so, what are my actual options for addressing that?
What ongoing filing obligations will continue even after any move or restructuring is complete?

Key takeaway A genuinely qualified cross-border tax professional should be comfortable naming the specific legal mechanisms involved, addressing reporting obligations as thoroughly as tax savings, and putting the recommended strategy in writing. If any of those three things is missing, treat that as a reason to get a second opinion before proceeding.

Questions specific to a program like Act 60

Based on my actual circumstances, do I meet the physical presence, tax home, and closer-connection tests as they currently exist?
Which specific categories of my income would the incentive actually apply to, and which would it not cover?
What ongoing documentation would I need to maintain to defend my bona fide resident status if it were ever reviewed?

Questions about credentials and accountability

What license or professional credential do you hold, and in which jurisdiction is it issued?
Can I verify that credential independently through a public state bar or licensing lookup?
If your recommendation is later found to be incorrect, what is your responsibility, and do you carry professional liability coverage?

Checking a professional's credentials through a state bar or professional-license lookup before paying for advice is a genuinely free, worthwhile step — it costs nothing and tells you something real, independent of how confident or polished the pitch sounds.

What a good answer sounds like, versus a red flag

A qualified professional's answers should sound specific: named tests, named forms, named treaty articles, a clear "it depends on X, and here's how we'd confirm X." A red flag answer sounds general and reassuring without being specific: promises that a move alone solves everything, vague references to strategies without naming them, or reluctance to discuss reporting obligations at all. Our guide on what a jurisdiction comparison should include covers this same pattern from the comparison side; this guide is the same idea applied to the professional relationship itself.

Bringing it all together

If you've read the other guides on this site, you now have the vocabulary and the framework to ask sharp, specific questions — which is genuinely the most useful thing a general educational resource can give you before a decision this consequential. The next step from here isn't more reading. It's a conversation with a licensed cross-border tax professional, armed with these questions, about your actual facts.

Questions about ongoing relationship and availability

Will you be available for ongoing questions as my situation develops, or is this a one-time engagement?
How do you stay current on changes to the specific countries' rules relevant to my situation?
If my situation involves a third country in the future, is that within your expertise, or would I need an additional professional?

Questions about fees and scope

What exactly is included in your fee, and what would trigger an additional cost?
Is your fee structured in a way that could create an incentive to recommend a more complex strategy than I actually need?
Can you provide a written engagement letter describing the scope of what you'll do before I commit to working with you?

How to use these questions in practice

You don't need to ask every single question in this guide in a single conversation, and a good professional won't expect you to arrive with a rehearsed script. What matters is that you walk in with the general categories in mind — residency, treaties, reporting, Act 60 or other program specifics if relevant, credentials, and ongoing scope — so that if a conversation skips one of these areas entirely, particularly reporting obligations, you notice the gap and ask directly rather than assuming it was covered. A genuinely qualified professional will welcome direct questions in every one of these categories; treating that welcome, or the lack of it, as information in itself is a reasonable and useful way to evaluate the relationship before committing to it.

Where this leaves you

This site was built around one core idea: legal cross-border tax planning is real, valuable, and available to people who take it seriously, and the same seriousness that goes into finding a tax-saving strategy needs to go into understanding and meeting the reporting obligations that come with it. If you've worked through the guides on this site, you now have the vocabulary, the framework for evaluating a jurisdiction comparison, and a specific list of questions for a professional. That's the complete, honest scope of what a general educational resource can responsibly give you — the next and final step is putting these questions in front of a licensed cross-border tax professional who can speak to your actual facts.

A short list to bring with you, printed or saved

Rather than trying to remember every question in this guide, it can help to bring a condensed version to your first conversation: what is my current residency status and what would change it; does a treaty apply between my countries and what does it cover; what exactly do I need to report and by when; what happens to my situation if I don't act at all; and what is your specific experience with my exact country pair. These five questions alone will surface most of what actually matters in a first conversation, and a professional's answers to them will tell you a great deal about whether they're the right fit for your specific situation before you commit further time or money.

This is general information about how cross-border tax concepts generally work, not individualized tax or legal advice — situations differ by country, citizenship, and personal facts, and a licensed professional should review your specific circumstances before you act.
