As a Croatian citizen working remotely - this would have been a much better deal pre-covid. Ever since we entered the eurozone and the EU funds started pouring in the prices skyrocketed (even compared to the rest of Europe, not just global inflation). Still worth looking into, but not a nobrainer like it was. Quality of life you used to be able to get for the mentioned 3.5k eur/month income was hard to get elsewhere in EU, but nowadays prices rose faster then the rest of Europe and quality of life stayed the same, a lot of other places in EU are competitive.
johnny_reilly•1h ago
I've just come back from my first trip to Croatia, and this rings true. It's a beautiful place but the prices are high! To quote one of the taxi drivers I chatted to "all the prices have gone up, but is okay; wages have stayed same" - deadpan
rafaelmn•1h ago
Depends on what you are looking at - but yes. Wages also rose considerably, below inflation, but still I think thats the same story as everywhere else.

I think the main difference is that (in my opinion) Croatia used to be unbeatable for the price/quality of life ratio, nowadays it's probably slightly overpriced, but depends on what you value.

willvarfar•1h ago
Is the cost of living inflation relative to income fuelling the current shift to the right in Croatian politics? This was on the international news yesterday: https://www.bbc.com/news/articles/cz60nyp3714o

Not really - there is no right shift, Croatia is very catholic and right leaning since the civil war. But at the same time the I would say it's mostly performative and not really that extreme as painted in the article.

It is something that is not well understood about the Euro, it is a deal with the devil, with all the hallmarks of looking like a wonderful idea where wishes and imagination blind one to the details and the tricks one opens oneself up to. It immensely benefits the ruling class and the upper class, and even foreigners at the expense of the working and middle class and the indigenous.

It was also that way for the Germans who are accused of having benefited at the expense of others, when that was really more an effect of national scale, not all Germans individually. The Euro has had an odd distorting and perverting effect all across Europe; but it has always generally been excellent for the ruling and upper class that have gained access to an overflowing trough of other people’s money at the EU.

The Euro has been a kind of wealth transfer mechanism to the ruling, upper, and even foreign classes, just as it has been a tool to restore the aristocracy just as it had in the USA; the aristocracy gets the money, the people get the inflation and debt that fuels the fraud.

We shall see if it all goes off the rails and the people establish legitimate democratic rule, or if the authoritarian aristocracy can fully entrench itself again.

Still not to bad, don't scare people off. Here are some comparisons of cost of living - to Vienna, but you can choose what to compare.

For example living in Split is cca 26% cheaper than Vienna.

And much cheaper in real terms, as the Croatian digital nomad residence permit provides an exemption from income tax on earned income.
rafaelmn•1h ago
Yeah but you can't compare living in Vienna and Split - Vienna is a top tier city - huge regional capital with so many things going on and offerings. Split is a C tier city dead outside of tourist season, like the rest of the coast. 26% is kind of ridiculous when you compare the standard of living.

Again depends on what you value, some might find it worth, just saying the equation was much more in Croatia favor 5 years ago.

keiferski•1h ago
This is not a good comparison.

Split has great weather for much longer than Vienna, and people are almost certainly spending time there to be next to the sea, islands, etc. – of which Vienna has none.

rafaelmn•1h ago
I didn't pick Vienna as a comparison, I just said that cost of living and living standards between two are very much out of proportions.

But you can compare to cities in Italy, Spain, Greece, etc. the choice is nuanced and based on what you value. It used to be a clear win for Croatia a while back.

keiferski•1h ago
“Living standards” includes things like access to the sea and better weather.

Not everyone cares about having access to the urban amenities that Vienna has. Split is also a pretty nice place, even off-season (I once lived there for 3 months February-April.)

That is why the costs of living between the two are not as disparate as you might expect.

rafaelmn•52m ago
Yes but you can also live in other cities in Europe on the coast with similar or lower prices and different tradeoffs. This is my entire point - this was not the case a few years ago - I would say all the comparable coastal regions in the EU were more expensive.
throwaway290•1h ago
Some people care about sea and islands but others care about culture and arts and Vienna wins on that? If sea and islands is what you want, most of south Asia is loads cheaper than Croatia!

As Portuguese, I can relate as I have seen what the euro has brought, positive and negatively as well.

For example 1 euro = 200.482 escudos, and when euro came we had stuff happening like 50 cents escudos becoming 50 cents in euro, I bet something similar has happened in Croatia.

Those 50 cents across coins are naturally not the same value, especially when the income wasn't suffered the same valuation across monetary systems.

rafaelmn•1h ago
Yes I believe Portugals and Croatias stories are very similar, your capital being a coastal city probably makes it even worse with regards to tourist inflation.
pjmlp•1h ago
Unfortunally tourist inflation, digital nomads, and foreign pensionists have driven house prices sky high, prevented the usual system of house renting for university students and people unable to buy houses, with crazy rents, as landlords rather profit from foreigners, thus that is how we end with a mostly right goverment, the far right having a large majority, with my parents and many others having fought the dictatorship for nothing.

No, it's a transitionary step before Governments introduce more comprehensive taxation regimes. You already can't work even a single day in many developed countries with becoming liable to the local taxation regime and as desirable locations developer, they inevitably have to restrict access due to overcrowding and taxation (along with visa availability) is the key lever available.

What AI is doing very effectively is allowing tax authorities to identify digital nomads illegally working in jurisdictions without registering for tax.

oytis•1h ago
I think the purpose of digital nomad visa is exactly to get their taxes. As opposed to say Germany where it's close to impossible to work for a overseas company even as a citizen, not to say get a visa for that
closewith•1h ago
No, that's not the case for the most part. For example, the Croatian digital nomad residence permit that this article is about provides an exemption to income tax for earned income while working for a foreign company and living in Croatia. This means that most digital nomads can work tax-free in Croatia.

This contrasts with, for example, Ireland, where not only does a digital nomad's income become subject to local tax on day 1, so does their company (if they are the beneficial owner).

Croatia's approach is excellent if you want many wealthy (compared to local standards) people to bring an influx of hard currency into your economy, at the cost of inflation. Eventually the benefits outweigh the costs and the government begins to subject digital nomads to local taxation and stricter visa rules.

mschuster91•1h ago
> As opposed to say Germany where it's close to impossible to work for a overseas company even as a citizen

That's by design of our employment laws. We are the ones whose social security system will have to pay up when the employer closes down shop or fires their remote employees over night, and we are the ones whose health system has to take care when people burn out from being overworked, so we demand that employers create a local subsidiary with people and bank accounts we can hold accountable when laws are being violated.

Oh, and we also want to make sure that people and companies pay their taxes.

pjmlp•1h ago
As someone working mostly remote across DACH, it is possible, but naturally the official residence and taxes have to be here.
mschuster91•53m ago
Well, that's what the problem is. When all you as an US startup want is to hire a single or maybe a dozen Europeans, you can either go and pay them in cash or as sole-proprietors and leave the employees to deal with the rest (as long as the US gov't gets its taxes, you're in the clear from the IRS point of view), you hire some intermediate body-shop, or you do it the proper way and pay a loooooot of money for a subsidiary.

Politics are making it more complicated. Many countries are taking a less friendly stance on foreigners occupying valuable real estate and pushing prices higher without assimilating the culture. Like anything, the real answer is, “it depends”.

And so they should. It looks like a fun trend until you realise how little digital nomads give back and how much they take.
FirmwareBurner•1h ago
It doesn't matter what they contribute to the government and local communities, the digital nomad visa wasn't built with that in mind.

Digital nomads make landlords and property owners richer so there's a high chance the system will be allowed indefinitely since a lot of Croatians are property owners so they directly or indirectly benefit from this gentrification.

The system will only be challenged in politics once enough young Croatian voters find themselves priced out of their own cities like in Barcelona or Lisbon.

The local economy also gains from the small but continuous spend on restaurants and cafes etc, and the spend is encouraged to be year-round and not just in peak holiday season.
FirmwareBurner•59m ago
>The local economy also gains from the small but continuous spend on restaurants and cafes etc

Speaking as someone living in Austria ATM, that's the worst kind of industry you want to boost if you want more money in the community, as it only creates dead-end low wage unskilled jobs(often taken by seasonal immigrants who send that money home) and is rife with cash-driven tax evasion, leading to more wealth and income disparity. If you get more and richer tourists, you won't get better paid baristas or waiters with better pension plans, but wealthier business owners who will buy more properties and flashy cars while still hiring the cheapest most desperate labor possible from abroad.

As a government, you should do the opposite, focus on attracting or creating highly skilled innovation jobs (like NL or Sweden did) and the hospitality jobs will follow naturally.

There's a reason countries where the tourism industry is a big part of the GDP, are low income countries.

Unreal that you can't see the obvious logical flaw in this argument.

mschuster91•1h ago

Outside of the direct coastal areas that already struggle with this issue from tourism, the brain drain that followed the 90s Independence War still left a sizable amount of empty real estate just sitting around.

And even in the direct coastal areas... a place to live is cheap. In doubt, just buy it, usually young people pool together some cash from relatives and some from bank loans to get started. Or they build it piece by piece, floor by floor, just like my grandparents did. Work a few years in a good job abroad, return to the homeland, build a house.

Grimburger•1h ago
This is a ridiculous claim probably very biased by a local worldview given that the number of DN visas has exploded in the last 2 years.

I've been working remote for 8 years now and it's never been easier and the amount of options worldwide is unreal.

mattmanser•52m ago
I don't think it's ridiculous, you might even argue we're at "peak" digital nomad. There's definitely pushback building, here's an example from recently:

‘There’s an arrogance to the way they move around the city’: is it time for digital nomads like me to leave Lisbon?

https://www.theguardian.com/world/2025/jul/27/lisbon-portuga...

I know the guardian can be very hand wringy, but digital nomads are going to get swept up in the general anti-migration narrative that most populaces are now feeling. Anti-mass-migration in most populations, anti-tourist in Venice, anti-nomad in Portugal.

Locals are feeling betrayed by their politicians and foreigners are an easy target to point at and say "why is this happening". The Lisbon example is especially egregious, with the digital nomads being taxed less than locals. Locals are subsidizing their lifestyles.

Grimburger•21m ago
> but digital nomads are going to get swept up in the general anti-migration narrative that most populaces are now feeling

Can you name one digital nomad visa that has been scrapped in the last year or two?

I can name a few dozen that have been implemented.

When I started in 2017 there was maybe 3 or 4 places you could move on Earth with a six figure USD salary as a remote worker, it was always a grey zone to go places on tourist visas but that's how people rolled and countries knew how good a deal it was for them compared to raising/educating/supporting locals so let it slide. There's over 70 legal valid options now for remote workers in 2025.

The easily proven evidence doesn't stack up with the narrative people and newspapers likes the Guardian are trying to push for clicks.

I personally couldn't care less if locals don't like me. My own countrymen are jealous about me having a good paying remote job too.

tmountain•41m ago
I live in Portugal, and there is a robust debate around this topic. It's far from ridiculous, and nationality laws are in the process of changing as a component of this discussion.

Also, many countries are "tightening down" their golden visa programs or removing them entirely. I have a friend who works for a golden visa consultancy, and they're already in the process of pivoting because of so many changes.

Grimburger•28m ago
> I live in Portugal, and there is a robust debate around this topic.

Assumed it was somewhere in that region because my European friends usually talk about it. Personally find it bizarre because the few thousand digital nomads are barely moving the needle compared to tourism or normal migration. It comes across as people getting very upset about a minor issue because they have rigid ideological views that prevent them from touching the main one. A convenient scapegoat but nothing will change in the slightest if the Portugese DN visa is scrapped.

You've created the easiest pathway to a EU passport and then wonder why the planet flocks there.

The simple solution here is to build enough housing to meet demand.

It’s actually a terrible toxic idea that guarantees that anywhere beloved, prized, peaceful or beautiful becomes unaffordable as international jet setting tech people nurse a single cappuccino with their laptops in family-run cafés all around the world while driving up the price of property.

I am living in a Digital Nomad hotspot, and you are painting a dystopian picture that is not reality. Most DNs I know work either from Home or Coworking Spaces, which have sprawled up everywhere. You pay around 150-250€/month for your own desk. There are also now "coworking cafés", that usually target DNs and Coworkers by charging a flat fee (i.e. 5€ a day) a give either a free coffee included, or 10%-20% rebate on drinks/food. These cafés are specifically setup for Laptops (i.e. single table layouts). Other cafés that had those "nursing people" simply put up signs disallowing laptops - which is at every café owners discretion to do so.

In my experience, the local starbucks is crowded with tourists and their laptops (or tablets with keyboards), but these folks are not DNs, they are just waiting for their plane or airbnb to get ready.

Regarding property price and high rent, this discussion is pretty stupid. Every country wants richer-than-average people to come and pay taxes and/or spend their money. I often hear the bogus argument that DNs don't pay taxes which is bullshit, because even DNs pay taxes indirectly, as every amout they spend is someone elses taxable income (this includes rent). If they don't come, those incomes won't exist and no taxes be paid.

Most places in Europe bring in millions of poor immigrants, while some countries (most prominently spain) the people complain about rich immigrants...

leononame•48m ago
I live in what's not exactly a digital nomad hotspot, but they do come. You pay 150€/month for a coworking space in a city where some people pay 300-400€/month rent. These digital nomads come here, pay absurd amounts of rent without blinking an eye.

And the tax thing is not a bogus argument. When people only pay taxes indirectly, they are tourists. Digital nomads pay _much_ less tax overall than other people, because people who pay income tax pay indirect taxes as well. If the digital nomads don't come, they also wouldn't raise rent and café prices for everyone around them. You come here, register yourself as a freelancer and pay income tax? You're very welcome in my book. But if you come to the country to leech off its cheap prices but don't pay income tax, you can go back where you came from.

We bring in millions of poor immigrants for various reasons: It's the human thing to do, these immigrants do cheap and hard labor that a lot of natives won't do (think construction, food delivery, etc.) and as such even provide benefits to us.

Digital Nomads mostly aren't immigrants. They come for a limited time, don't provide much to the local economy outside spending some money (and even then it's not that much because a lot of them come to cheap countries to live for cheap and save money) and then leave again. It's not really comparable.

kristoff200512•56m ago
The arrival of digital nomads will not fundamentally drive up a country’s or a city’s housing prices, as they usually only rent. Renting has no direct impact on the development of local housing prices. On the contrary, the influx of digital nomads can actually increase the income of most low-cost countries, since they will inevitably spend money locally.
baq•45m ago
more renters than apartments/homes => rents go up => cap rate goes up => new home prices go up. it isn't instant obviously, but if the renters keep coming and new developments don't accelerate, prices will keep going up. see bay area for a market that keeps going up for two decades or whatever.
Ekaros•44m ago
Renting does have direct impact on housing prices. As the price landlords pay for units is based on rent they can get. If rent they can get goes up, so does the amount they are willing to pay.

Even I, who doesn't require anyone to be in any sort of office (we don't even have one) only hire people from the same country my company is registered in. I've hired full time employees from other countries before, but it's quite the hassle bureaucracy wise.

So yeah, I'm sure it's possible to find remote work from Croatia, especially in Europe cause it's a bit less hassle to employ someone across borders between EU countries. But I do think the chances of finding even a remote job are higher if you're based in a country with plentiful employers.
