Tax residency for digital nomads: where you actually pay tax

The million-dollar question for any digital nomad: if I don't live anywhere fixed, where do I pay tax? The answer is less romantic than it sounds.

The 183-day rule

Most countries use the 183-day rule as the main criterion: if you spend more than 183 days in a calendar year in a country, you're a tax resident there. But it's not the only criterion.

Many countries also consider:

• Center of vital interests: where your family, home and main bank are
• Habitual abode: where you return regularly
• Quarantine clause: some countries (like Spain) can claim you as a tax resident for up to 4 years after you leave, but only if you move to a non-cooperative jurisdiction (tax haven). If you move to a country with a Double Taxation Treaty with Spain, the rule does not apply.

The "I'm not a resident anywhere" myth

Legally, you are always a tax resident somewhere. If you can't prove residency in a specific country, your country of nationality can claim you. And if two countries claim you, the relevant Double Taxation Treaty (DTT) applies.

Having no tax residency is a risk, not an advantage. Your home country's tax authority can treat you as a resident if you can't prove you're one elsewhere.

Real options for nomads

Paraguay

Territorial system: you're only taxed on income generated inside Paraguay. Income from your US LLC? 0% tax in Paraguay. Residency obtainable in weeks, with minimal physical presence.

Dubai / UAE

0% personal income tax. Requires a residence visa and periodic minimum presence (exact requirements vary by visa type). Maintenance cost is higher than other options. Check current requirements with a local advisor before choosing this option.

Georgia

Territorial regime for habitual non-residents. 1% tax for small businesses. Easy to obtain residency.

Portugal (former NHR)

Portugal had the NHR regime, which exempted certain foreign income for 10 years. The program was discontinued for new applicants in 2024 and replaced with a more limited incentive (IFICI). If your NHR was already approved, the regime continues for the remaining period. For new residents in 2025-2026, the conditions are different and more restrictive.

LLC + tax residency = the combo

The optimal structure for many nomads is:

1. US LLC as the billing vehicle (fiscally transparent entity: no corporate-level tax if income isn't connected to a US trade or business)
2. Tax residency in a territorial-system country (0% on foreign income)
3. Mercury bank account to operate in USD
4. Wise/local account for day-to-day expenses

All legal, all declared, all optimized. The key is having each piece documented and in compliance — that's the economic substance that makes the structure survive a review, not just paper with an address. And mind your starting point: if you're still a tax resident in Spain, the LLC doesn't get you out of there on its own. The infrastructure is also moving so fast that we've already reached the point where an AI agent can hire you an LLC without you having to click through anything.

If you don't yet have a clear sense of the difference between operating as a European self-employed worker or with a US LLC, the detailed comparison is in our article on LLC vs. self-employed in Europe. And to understand the international tax-residency framework and how countries coordinate their criteria, the OECD Model Tax Convention is the reference all current double-taxation treaties rely on.

Frequently asked questions

Can Spain still treat me as a tax resident after I move?

Only in one specific case: the quarantine clause lets Spain claim you for up to 4 years after you leave, but only if you move to a non-cooperative jurisdiction (a tax haven on the official list). If your new country has a Double Taxation Treaty with Spain, the rule doesn't apply. The real risk isn't the quarantine itself but failing to prove your new residency: review it in the Spanish tax authority and your US LLC.

Does my US LLC pay tax if I live in a territorial-system country?

On your foreign income, usually no. A single-member LLC is fiscally transparent (no corporate-level tax if the income isn't connected to a US trade or business), and a territorial regime taxes only what's generated inside the country: 0% in Paraguay on foreign income, 1% in Georgia for small businesses. The piece holding it all together is documented economic substance, not paper with an address.

Can I be a tax resident of no country at all?

Not legally. You are always a tax resident somewhere: if you can't prove it in a specific country, your country of nationality can claim you. The 183-day rule is the main criterion, but not the only one — center of vital interests and habitual abode count too. "Having no residency" is a risk, not an advantage.
