Which of These Four Visas Has the Lowest Tax Rate?
Bulgaria does, on paper — it taxes personal income at a flat 10% once you become a tax resident, one of the lowest rates in the European Union, according to PwC’s Bulgaria tax summary.
Croatia can actually beat that rate for some nomads. If you stay under 183 days in a 12-month period, Croatia exempts your foreign-source income from local tax entirely, effectively taxing you at 0% locally rather than Bulgaria’s flat 10%.
Portugal and Estonia don’t offer a comparable flat-rate carve-out for digital nomads. Portugal’s D8 visa holders generally fall under the country’s standard progressive income tax once they become residents, and Estonia taxes residents at its own standard rate with no nomad-specific discount.
I found that Bulgaria’s tax advantage only really pays off if you actually cross the 183-day residency threshold. Stay fewer days than that and you’re taxed close to how any short-term visitor would be, which erases most of the headline benefit people quote when they compare these programs.
How Much Income Do You Need for Each Visa in 2026?
Bulgaria has the lowest bar of the four. It requires proof of income equal to about 50 times the monthly minimum wage, which lands around $36,168 USD per year under the program’s official terms.
Croatia sits in the middle at roughly €3,622.50 per month as of March 2026, or you can qualify with savings of at least €43,470 for a 12-month stay.
Portugal requires proof of monthly income of at least €3,480, four times the country’s minimum wage, plus a separate bank balance requirement of about €11,040 — 12 times the minimum salary — per Portugal’s official AIMA guidance.
Estonia sets the highest bar in this group at roughly €4,500 in average monthly income over the six months before you apply, according to Estonia’s official e-Residency program FAQ.
Does Spending 183 Days Trigger Tax Residency Everywhere?
Yes, in Bulgaria specifically — you become a Bulgarian tax resident if you spend more than 183 days there during any 12-month period, and that residency status then applies to your worldwide income, not just what you earn locally.
Croatia flips that same threshold into a benefit instead of a trigger. Stay under 183 days and your foreign-sourced income stays exempt from Croatian tax. Cross it, and you lose that exemption.
Here’s where people get tripped up: the visa itself doesn’t decide your tax residency in any of these four countries. Your actual day count does, and a country can still treat you as a tax resident even under 183 days if your “center of vital interests” — family, main bank accounts, primary home — sits there instead.
Which Visa Lets You Stay the Longest?
Bulgaria’s permit runs one year and can be renewed once, giving you up to two years total under the current program.
Portugal’s D8 visa is generally renewable beyond that initial period for nomads who keep meeting the income and residency requirements, making it the most open-ended of the four for anyone planning a multi-year stay.
Estonia caps a single Digital Nomad Visa stay at 12 months from your date of entry, with no renewal built into the same visa category.
Croatia is the strictest here. Its digital nomad permit runs 6 to 18 months and explicitly cannot be renewed or extended past that 18-month ceiling — when it ends, you have to leave and reapply fresh later.
Tax and Visa Terms Side by Side
| Country | Tax Treatment | Minimum Monthly Income | Max Stay |
|---|---|---|---|
| Bulgaria | Flat 10% once tax resident (183+ days) | ~$3,014 (50x minimum wage/year basis) | 1 year, renewable once (2 years total) |
| Portugal | Standard progressive tax once resident | €3,480 | Renewable beyond initial period |
| Estonia | Standard tax, no nomad discount | €4,500 | 12 months, no renewal on same visa |
| Croatia | 0% local tax on foreign income if under 183 days | €3,622.50 | 6–18 months, cannot renew or extend |
How Do You Actually Apply for Each Visa?
Bulgaria starts abroad. You file a long-stay Type D visa application at a Bulgarian embassy first, which typically takes one to two months. After you arrive, you apply for the residence permit itself at the Migration Directorate within 14 days, and that stage adds another two to four weeks.
Portugal routes everything through AIMA, the country’s immigration and asylum agency. You submit your application in person at an AIMA office along with a signed declaration confirming your remote work relationship and proof of accommodation.
Estonia lets you apply three ways: directly through an Estonian embassy that handles visas, in person at a Police and Border Guard office, or through a VFS visa center. The standard processing clock is 30 days once your complete application reaches the board.
When I checked each country’s official application portal, Croatia was the only one of the four running the entire process through a dedicated online system built specifically for digital nomads, rather than folding it into general immigration paperwork. You can apply through that portal directly or in person at a local police station.
Where These Visas Get Complicated Fast
Estonia’s program isn’t open-ended even if your paperwork is perfect. The government sets an annual immigration quota, and for 2026 that quota sits at 1,292 slots total — miss the window and you’re waiting for the next cycle regardless of income.
Croatia’s permit can’t be renewed, which sounds simple until you realize it means planning an exit strategy the same day you plan your arrival. There’s no in-country extension path once you hit the 18-month ceiling.
Most people skip reading the fine print on center-of-vital-interests rules and regret it. You can spend fewer than 183 days in Bulgaria or Croatia and still get taxed as a resident if your spouse, kids, or main property are already based there — the day count isn’t the only test that matters.

Tips
- ✅ Count your actual travel days for the past 12 months before you pick a country — the tax math changes completely depending on whether you’ll realistically hit 183 days.
- ✅ Apply to Estonia early in the year if you’re set on that program — the fixed annual quota fills up, and there’s no fast-tracking around it.
- ✅ Budget for Portugal’s separate bank-balance requirement on top of the monthly income minimum — it’s easy to meet one and forget the other.
- ✅ If you want a renewable long-term base, weight Portugal or Bulgaria higher than Croatia or Estonia, since neither of those two extends past their fixed ceiling.
Warnings
- ⚠️ None of these four visas override your home country’s own tax rules — you may still owe tax at home depending on your citizenship and existing tax treaties.
- ⚠️ Bulgaria’s residence permit process does not by itself change your tax residency status; that depends entirely on your day count and center of vital interests, not the visa paperwork.
FAQ
Can you switch between these visas mid-year without losing tax benefits?
Generally no, and it can backfire. Splitting a year between two countries risks triggering residency tests in both places at once, since several use their own 183-day or center-of-vital-interests rules independently rather than coordinating with each other.
Do freelancers and remote employees qualify the same way?
Mostly yes, but the required proof differs. Bulgaria and Croatia both accept either an employment contract with a foreign company or invoices from foreign clients as proof of remote income, while Portugal and Estonia ask for similar documentation tailored to whichever category — employed or self-employed — actually applies to you.
Does EU citizenship change any of this?
Yes, significantly. These digital nomad programs are built for third-country nationals. EU and EEA citizens generally don’t need any of these four permits at all, since freedom of movement already covers their right to live and work across the bloc.
