American travellers abroad still face US taxes, but smart planning can reduce or even eliminate what you owe
You’ve traded the cubicle for Patagonian peaks and swapped rush hour for sunrise treks through Southeast Asian jungles. Passport stamps have become your most prized possessions. Living abroad as an adventure traveller is everything you imagined, until tax season arrives and reminds you that the IRS does not care how far off the grid you have gone.
Here is what catches many Americans off guard: unlike almost every other country, the United States taxes its citizens on worldwide income, regardless of where they live. Whether you are teaching scuba diving in Indonesia, running a travel blog from Portugal, or guiding mountaineering expeditions in Nepal, your tax obligations follow you.
The good news? Understanding the rules around filing expat taxes can save you thousands each year, money better spent on your next expedition. This guide breaks down the essential strategies every adventure traveller should know before the 2025 tax deadline.
Do American citizens living abroad have to pay taxes?
The short answer is yes, but it is more nuanced than that.
US citizenship comes with a unique tax burden. While citizens of most countries only pay tax where they live and earn, Americans are taxed regardless of where their income originates. This applies whether you earn through remote work, investments, rental income back home, or adventure guiding abroad.
However, owing tax and actually paying tax are not the same thing. The US tax system includes several provisions designed for expats that can significantly reduce, or even eliminate, what you owe. Understanding these is where smart planning begins.
filing requirement versus payment requirement
Many travellers confuse filing with paying. Even if your tax bill is reduced to zero, you will usually still need to file a return.
For 2025, single filers under 65 must file if their gross income exceeds $14,600. This applies regardless of where you live.
Failing to file can be costly. The IRS may charge penalties of 5% per month, up to 25% of the unpaid tax, plus daily interest. If your foreign accounts exceed $10,000 at any point, failing to submit an FBAR (FinCEN Form 114) can trigger penalties starting at $10,000 per violation.
the foreign earned income exclusion
For most adventure travellers, the Foreign Earned Income Exclusion (FEIE) is the single biggest advantage. For the 2025 tax year, you can exclude up to $130,000 of foreign-earned income from US tax.
To qualify, you must pass one of two tests:
The bona fide residence test requires you to establish genuine residence in another country for a full calendar year. This suits those settled in one place, for example, running a trekking company in Nepal.
The physical presence test requires at least 330 full days outside the United States in any 12 months. This is often a better fit for travellers moving between countries, as it does not require formal residency.
timing your travels strategically
This is where adventure travellers have an edge. With careful planning, meeting the physical presence test can be straightforward.
Imagine leaving the US in mid-January and spending the year travelling through South America, New Zealand and Southeast Asia. As long as you spend no more than 35 days in the US within any 12 months, you qualify.
The detail matters. A day only counts as ‘outside’ the US if you are abroad for a full 24 hours from midnight to midnight. Partial days spent in the US count against you.
the foreign tax credit
The FEIE is not always the best option. The Foreign Tax Credit (FTC) can be more beneficial, particularly for higher earners or those in high-tax countries.
The FTC allows you to offset US tax with income tax already paid abroad. If you live in countries such as Germany or Denmark, where rates are often higher than in the US, this can eliminate your US tax liability.
Can you use both?
Yes, but not on the same income.
You can exclude up to $130,000 using the FEIE, then apply the FTC to any income above that threshold. For travellers with multiple income streams across countries, this combined approach can be highly effective.
The foreign housing exclusion
In addition to the FEIE, expats can claim relief for housing costs.
For 2025, the base housing amount is $18,200. You can exclude or deduct eligible housing expenses above this figure, up to limits that vary by location.
Qualifying expenses include rent, utilities (excluding phone), renters’ insurance, furniture rental and parking fees. Property purchases, mortgage payments and domestic labour do not qualify.
If you move frequently, keep detailed records. Even short-term stays can count if they represent your main residence at the time.
additional reporting requirements
Filing your tax return is only part of the picture. Many expats must also submit:
- FBAR (FinCEN Form 114): required if total foreign account balances exceed $10,000 at any point
- FATCA Form 8938: required if foreign assets exceed $200,000 at year-end or $300,000 at any point (for single filers abroad)
- Form 3520: required for large gifts or inheritances from foreign individuals
Penalties for missing these can be severe, even if no tax is due.
practical strategies for adventure travellers
Stay organised. Track border crossings, days spent in each country and all housing costs. When moving frequently, it is easy to lose track.
Be mindful of US ties. Maintaining strong links, such as licences or registrations, can complicate residency claims under certain tests.
Time your income where possible. Freelancers and remote workers can often shift payments into years when they clearly qualify for exclusions.
Do not overlook state taxes. Some states, notably California, may continue taxing former residents. Establishing residency in a no-tax state before leaving can make a significant difference.
When to seek professional help
Expat tax can become complicated quickly. Multiple income sources, foreign investments and differing tax systems create grey areas that are easy to misinterpret.
If your situation is simple, expat-focused tax software may be sufficient. If not, professional advice can save money and reduce risk.
Your next adventure should not be overshadowed by tax uncertainty. Plan, keep accurate records and file on time. The mountains will still be there, and you will enjoy them more knowing your finances are in order.
