Three Digital Nomad Tax Mistakes That Cost People Everything (And How to Avoid Them)

I have spent enough time in nomad communities to notice a pattern: nobody talks about tax problems. They talk about the beach, the coworking space, the visa they just got approved for. Nobody posts on Instagram about the letter from the IRS.

But the letters arrive. The penalties accumulate. And the people it happens to almost always say the same thing: “I didn’t know.”

Here are three stories from real nomads who got it wrong. Their names are changed. The numbers are real.

Story 1: The $14,000 Surprise

Marcus was a freelance developer earning about $110,000 a year from US clients while living in Chiang Mai, Mexico City, and Lisbon. He qualified for the FEIE. He filed his taxes. He assumed everything was covered.

His accountant called him in March with the news: the FEIE excluded his income from federal income tax, but it did not touch self-employment tax. He owed 15.3% on roughly 92.35% of his net earnings. That came to about $15,500. He had set aside nothing for it.

Marcus is not unusual. The FEIE is the most misunderstood part of the US tax code for nomads. It zeroes out your income tax liability. It does nothing for self-employment tax. The only way to reduce it is through a Totalization Agreement with a country that has one with the US — and the countries most nomads live in (Thailand, Mexico, Portugal, Indonesia) do not.

The fix: if you are self-employed, set aside 15.3% of your income from the first dollar you earn. Do not wait until you know what you “actually” owe. The answer is 15.3%. Plan for it.

Story 2: The Frozen Account

Elena was an American working remotely through her own LLC while traveling across Europe. She opened a local bank account in Portugal — convenient for paying rent and avoiding foreign transaction fees. The balance hovered around $8,000 most of the year. She never filed an FBAR.

What Elena did not know: the FBAR threshold is $10,000 in aggregate across all foreign accounts — not per account, total. Her Wise account held another $5,000 for currency transfers. Combined, her foreign accounts crossed $10,000 at multiple points during the year.

The penalty for non-willful failure to file an FBAR starts at $16,536 per violation. For willful failure, it goes to the greater of $165,353 or 50% of the account balance. The IRS discovered the accounts through FATCA reporting — foreign banks automatically share US account holder information with the US government. Elena did not need to do anything wrong for the IRS to find her. The bank did it for her.

The fix: file your FBAR. It takes ten minutes. If your foreign accounts aggregate over $10,000 at any point during the year, you need to file. Do not assume small balances protect you. They do not.

Story 3: The “I Did Not Owe Anything” Assumption

David spent 2024 and 2025 traveling full-time. He never spent more than 90 days in any single country. He assumed that because he “lived nowhere,” he owed tax nowhere. He stopped filing entirely.

In 2026, David’s home country — the UK — contacted him. The UK’s Statutory Residence Test does not depend solely on day counts. It considers ties: a maintained UK address, a UK bank account, UK-registered vehicles, family connections. David had kept his parents’ address on his bank statements. He used a UK-registered phone number. His freelance contracts were with UK companies and paid into a UK account.

The tax authority determined he had sufficient ties to remain a UK tax resident despite spending fewer than 90 days there each year. He owed back taxes, interest, and penalties for two years of unfiled returns.

The fix: if you want to sever tax residency, sever it deliberately. Close the bank accounts. Cancel the phone number. Change the registered address. A tax authority will not assume you have left just because you bought a one-way ticket.

Three Rules That Would Have Prevented All of This

  1. If you are American, you must file. The US taxes based on citizenship, not residency. Even if you owe nothing, even if the FEIE covers everything, you file. The penalties for not filing are worse than the penalties for filing and owing.

  2. Track your days from day one. Every tax residency question eventually comes down to: where were you, and for how long? If you cannot answer that question with precision, you cannot answer any tax question with confidence.

  3. Spend $500 on a cross-border tax specialist before you spend $50,000 fixing a mistake. Your situation is more complicated than you think it is. That is true for everyone. A professional who handles expat and nomad taxes will identify risks you did not know existed.

None of this is tax advice. The stories reflect common patterns reported by nomads and tax professionals. Consult a qualified CPA or tax attorney for your specific situation.
