Taxes are the least glamorous part of remote work, and the most likely to cause serious, expensive problems. I learned this the hard way. My first year as a nomad, I filed my taxes wrong and spent $2,300 fixing a mistake that a $400 consultation would have prevented.

What follows are 10 questions to bring to a cross-border tax specialist. Not a guide, not a cheat sheet. Questions.

Why this matters now

The OECD Common Reporting Standard now connects over 100 countries, automatically sharing financial data across borders. AI compliance tools flag extended foreign work patterns. The Crypto-Asset Reporting Framework (CARF) is rolling out. Governments are actively closing loopholes.

A one hour consultation with a cross-border tax specialist costs $200 to $500. Fixing a tax problem after the fact can cost tens of thousands. I know which one I would rather pay for.

10 questions to ask your accountant

1. “Am I still a tax resident of my home country after I leave?”

Most countries do not stop taxing you just because you bought a one way ticket. The United States taxes citizens on worldwide income regardless of where they live. The US is one of only two countries that does this (the other is Eritrea). Other countries use factors like property ownership, bank accounts, family ties, and driver’s licenses to determine if you are still a resident.

Ask specifically about: What steps you need to take to formally sever tax residency, and whether doing so is actually beneficial for your situation.

2. “What is the difference between a digital nomad visa and tax residency?”

This is the single most common and most expensive misunderstanding among nomads. A visa is an immigration document: it gives you the right to be somewhere. Tax residency is a separate legal status determined by a different set of rules (days spent, center of vital interests, family location). You can hold a valid Spanish digital nomad visa and still be a full tax resident of your home country.

3. “Is the 183-day rule the only thing I need to worry about?”

The 183-day rule varies dramatically by country. Some countries use a calendar year (Spain). Others use a rolling 12-month window (Portugal). The US uses a weighted three-year formula where you can trigger residency without ever spending 183 days in a single year.

Ask specifically about: The exact day-counting method for every country you plan to spend significant time in, and whether partial days or transit days count.

4. “What happens if I do not establish tax residency anywhere?”

There is a dangerous myth in nomad circles: “I am always moving, so no country can claim me.” No legal framework is designed to create zero-tax situations. Countries use multiple criteria beyond day counts to claim residents. Being below 183 days everywhere often means you are vulnerable everywhere, not safe.

5. “Do I need to report foreign bank accounts?”

If you are a US citizen and your foreign accounts aggregate over $10,000 at any point during the year, you must file an FBAR (Foreign Bank Account Report). Penalties for not filing: up to $16,536 per violation for non-willful failure, and up to 50% of the account balance for willful violation, plus potential criminal charges. This applies regardless of whether the accounts generated taxable income.

Ask specifically about: FBAR, FATCA Form 8938, and any similar reporting requirements your home country has.

6. “Does the Foreign Earned Income Exclusion actually help me?”

For US citizens, the FEIE excludes up to approximately $126,500 (2026 estimate) of earned income from US federal income tax. But it does nothing to reduce the 15.3% self-employment tax. A freelancer earning $130,000 abroad might owe $0 in federal income tax but still face approximately $19,890 in self-employment tax.

Ask specifically about: Whether FEIE or Foreign Tax Credit is better for your situation, and whether an S Corporation election could reduce your self-employment tax burden.

7. “Could my work create a permanent establishment for my company?”

If you are making strategic decisions, signing contracts, or managing revenue from a foreign country, that country may determine your business has a permanent establishment there. This triggers corporate income tax, VAT, and payroll obligations. The OECD’s November 2025 update introduced a 50% working-time benchmark for this analysis.

This matters especially for founders and business owners, not just employees.

8. “Which countries have tax treaties with my home country, and what do they actually cover?”

Tax treaties exist to prevent double taxation, but they are not magic shields. Nearly every US tax treaty contains a saving clause that preserves America’s right to tax its own citizens. Treaties help with foreign tax credits and social security totalization, but rarely provide blanket relief. And if you do not have tax residency anywhere, you typically cannot claim treaty benefits at all.

9. “What records do I need to keep, and for how long?”

If challenged by a tax authority, you need evidence. The documentation that carries the most weight (tax filings, residency certificates, long term leases) requires deliberate action to create. Flight itineraries and Airbnb receipts carry less weight than most people assume.

Start tracking from day one: dates in each country, flight records, lease agreements, bank statements showing where transactions occurred.

10. “What am I not asking that I should be asking?”

A good cross-border tax specialist will identify risks specific to your situation: your citizenship(s), your income structure, your travel patterns, and the countries you are considering. There is no one size fits all answer in international tax.

How to find the right professional

Look for someone who handles cross-border and expat taxation, not just a domestic CPA
Specialists include: Greenback Tax Services (US expats), Corpenza (global), and independent cross-border CPAs
Expect to pay $200 to $500 for an initial consultation
Ask them directly: “How many clients do you have with situations similar to mine?”

Bottom line

I spent $2,300 fixing a tax mistake I could have avoided with a $400 consultation. If you are about to leave your home country, know where you are a resident, understand your reporting obligations, and keep records from day one. A professional can help with all three.

FAQ

If I leave my home country, do I still owe taxes there?

It depends on your citizenship. The United States taxes citizens on worldwide income regardless of where they live. Most other countries tax based on residency. If you are a US citizen, you must file a federal tax return every year even if you never set foot in the US. The Foreign Earned Income Exclusion (FEIE) allows you to exclude up to $130,000 of foreign-earned income in 2026, but it does not exempt you from self-employment tax. Read about how the 183-day rule actually works.

What happens if I just do not file?

The IRS and most other tax authorities will eventually find out. Penalties accumulate. Interest compounds. Banks freeze accounts. Countries share financial data through automatic information exchange agreements. A tax mistake can cost you everything. Talk to a professional before you leave.

When should I hire a cross-border tax professional?

Before you leave your home country. The consultation costs $200 to $500 and will save you multiples of that in avoided penalties. Look for someone who handles expat and cross-border taxation, not a general domestic CPA. See our full guide on US digital nomad taxes for more detail.
