We've had this conversation more times in the past eighteen months than in the five years before it. A client holds a digital nomad visa for Portugal, or Spain, or Georgia, or Indonesia. They've been living there for over a year. They assume, reasonably on the surface, that this is where they're now tax resident. Then their home country's tax authority sends a letter, or their accountant asks an inconvenient question, and it turns out they may owe tax in two countries for the same income, in the same year, with no clean way to resolve it before the deadline.
The visa and the tax residency are not the same thing. Almost every digital nomad visa programme was designed by an immigration ministry to attract remote workers and their spending power. Almost none of them were designed with the tax authority in the room. That gap is where the expensive mistakes happen.
Why a visa doesn't set your tax residency
Immigration status answers one question: are you legally allowed to be in this country. Tax residency answers a completely different question: which country's tax authority has the right to tax your income, and it's answered separately, under separate rules, usually by counting days. Most countries use some version of the 183-day test — spend more than half the tax year physically present, and you're tax resident, visa or no visa. Some use more complex "centre of vital interests" tests that look at where your family lives, where your primary home is, and where your economic ties sit, regardless of day count. A digital nomad visa gets you legal permission to be present. It says nothing about which of these tests you've triggered, and it says nothing about whether your home country still considers you tax resident there too.
This is the trap: a person can hold a valid digital nomad visa, spend the requisite time abroad to satisfy the visa's own presence requirements, and still remain fully tax resident in their home country — while simultaneously tripping the host country's residency threshold as well. Two tax residencies, one income stream, and a double tax treaty that may or may not cover the specific facts cleanly.
Where this actually bites
The home country doesn't automatically let go. Several jurisdictions — the UK's Statutory Residence Test and several EU countries' domestic rules among them — will keep taxing you as a resident until you've affirmatively broken residency under their specific rules, which usually means more than just leaving. Ties to a spouse, a property, or a company directorship back home can keep residency attached even after a year abroad on a nomad visa.
The host country's tax rules and its visa rules run on different tracks. Georgia's visa programme, for example, has immigration presence requirements that don't map cleanly onto Georgia's own tax residency day count. A person can be visa-compliant and still ambiguous on host-country tax residency, which is not a comfortable place to be when a bank or a tax authority asks for a certificate of residency you don't clearly have.
Employers add a second layer entirely. If the "digital nomad" is drawing a salary from a home-country employer rather than running their own business, the employer may now have payroll withholding, permanent establishment, and social security obligations in the host country that neither the employee nor the employer anticipated when the visa was approved. This is a growing enforcement area, not a theoretical one — several EU tax authorities have started actively cross-referencing visa registrations against payroll filings.
Double tax treaties don't automatically fix it. A treaty tie-breaker can resolve dual residency on paper, but only if both countries agree on the facts, and only if someone actually files the position correctly, on time, in both jurisdictions. Left unaddressed, dual residency doesn't resolve itself — it sits there generating exposure until someone asks.
What actually determines tax residency, visa aside
Every jurisdiction weighs some combination of these, and the weighting is what a nomad visa never touches:
- Physical presence day count, tested against that specific country's threshold, not a round number you've heard secondhand
- Location of a permanent home available to you, not just where you're currently renting
- Where your economic and personal ties sit — spouse, children's schooling, primary bank accounts, company directorships
- Whether you've taken the affirmative steps your home country requires to break residency, which is a formal test in several jurisdictions, not a default that expires
A visa can coexist with any answer to any of these. That's precisely the disconnect.
How we actually structure this for clients
We treat the visa as the immigration layer and build the tax residency position as a separate, deliberate decision — not an assumption. In practice that means: confirming the home country's specific residency-break test and completing it properly rather than partially, checking the host country's tax-specific day count against its visa presence requirement (they are rarely identical), reviewing whether the income is drawn as salary, dividends, or business profit, since each is taxed and sourced differently under most treaties, and obtaining an actual certificate of tax residency once the position is clean — not relying on the visa card as evidence, because it isn't.
For clients earning through their own company rather than a foreign salary, this usually pairs with an entity decision — where the company is incorporated and managed frequently matters more to the tax outcome than where the founder happens to be sleeping. That's a separate conversation, but it's one we have in the same sitting as the residency question, because the two decisions constrain each other.
The practical takeaway
A digital nomad visa is a good, sometimes excellent, immigration tool. Treat it as your tax residency plan and you're relying on a document that was never built to answer that question. The fix isn't complicated, but it does need to happen deliberately, with both countries' rules checked against the actual facts — not assumed from the visa approval email.
Tax residency rules are jurisdiction-specific and change with domestic budgets, not on a fixed schedule. This guide reflects the general framework as of August 2026; confirm current thresholds for your specific countries before relying on any day count.
