Quick answer: Portugal, Andorra and Dubai can all be attractive tax residences, but for very different people. Portugal tends to fit those who want to remain inside the EU and either qualify for IFICI or accept ordinary European taxation. Andorra is particularly compelling for founders and professionals who value proximity to Spain and can genuinely relocate their life to a low-tax jurisdiction. Dubai / the UAE can be exceptionally attractive for internationally mobile founders and investors willing to live outside Europe and build real residence there.
The wrong comparison is “20% vs 10% vs 0%”. Those numbers relate to different systems, different income categories and different eligibility rules.
The useful question is:
Which jurisdiction fits my income, company, wealth, family and actual lifestyle?
Portugal vs Andorra vs Dubai: quick comparison
| Factor | Portugal | Andorra | Dubai / UAE |
|---|---|---|---|
| Personal income tax | Ordinary IRS; IFICI for qualifying profiles | General maximum IRPF rate of 10% | No general individual income tax |
| Worldwide income | Residents generally taxed on worldwide income | Residents taxed under Andorran IRPF rules | No general personal income tax, although business activity can enter Corporate Tax |
| Special regime | IFICI is activity-specific | No equivalent temporary expat regime required for the low general rate | Low personal taxation is part of the ordinary system |
| Proximity to Spain | Very high | Exceptional | Low |
| EU environment | Yes | Not an EU Member State | No |
| International business | Works well but ordinary European taxation applies unless incentives fit | Strong where genuine Andorran activity exists | Highly developed international business environment; Corporate Tax must be modelled |
Portugal: NHR is no longer the general answer for new arrivals
A major mistake is still describing Portugal through the old Non-Habitual Resident — NHR regime.
The Portuguese Tax Authority confirms that NHR was repealed from 1 January 2024, while existing beneficiaries and specific transitional cases remain protected.
For genuinely new relocations, the main special regime to test is the Tax Incentive for Scientific Research and Innovation — IFICI.
What IFICI can offer
Where its conditions are satisfied, IFICI can provide:
- a special 20% rate on qualifying Portuguese employment and professional income;
- as a general rule, Portuguese exemption for qualifying foreign-source income;
- a potential duration of up to 10 years.
However, the regime is targeted.
It can apply to specific scientific, innovation, technology and highly qualified roles, directors and professionals working for qualifying companies or sectors.
It is not a replacement NHR available to every freelancer, entrepreneur or retiree.
Foreign pension income is also excluded from IFICI’s general foreign-income exemption.
Who tends to fit Portugal best?
Portugal is particularly worth testing where:
- remaining inside the EU is important;
- family continuity and geography matter;
- you want to remain close to Spain;
- your role and employer can satisfy IFICI;
- you work in technology, innovation, research or another qualifying activity;
- you prioritise a European lifestyle over achieving the lowest possible nominal personal tax rate.
Portugal can still work without IFICI, but then ordinary Portuguese IRS must be compared with the alternatives.
Portugal’s residence test is not only a day count
Portugal can treat an individual as resident where they:
- spend more than 183 days, consecutive or otherwise, in a relevant 12-month period; or
- spend less time but maintain a Portuguese home in circumstances indicating an intention to occupy it as their habitual residence.
Portugal also operates a form of partial-year residence in certain circumstances, which can matter when planning the year of arrival.
Andorra: low tax and proximity, but only if the move is real
Andorra uses a very different model.
The Andorran Government states that its general Personal Income Tax rate reaches a maximum of 10%, with lower effective taxation in certain lower income bands.
This is not a temporary expat incentive. It is part of Andorra’s ordinary tax system.
Andorran tax residence: 183 days or economic centre
Andorran law treats an individual as tax resident where either:
- they spend more than 183 days during the calendar year in Andorra; or
- the principal centre or base of their activities or economic interests is located there, directly or indirectly.
A rebuttable family presumption can also apply.
It is important not to confuse tax residence with immigration permits. Some immigration categories use different minimum-presence conditions; those should not be presented as the general Andorran tax-residence rule.
Active and non-lucrative immigration routes in Andorra
The administrative route depends on the person.
For self-employed residence, the current Andorran procedure includes a €50,000 non-remunerated deposit with the Andorran Financial Authority, together with the relevant corporate, professional and immigration requirements.
For the relevant non-lucrative residence route, current official documentation refers to a permanent and effective investment of at least €600,000 in Andorran assets, subject to the complete immigration rules.
Andorra can therefore combine low personal tax with a higher economic or administrative entry barrier than Portugal.
Who tends to fit Andorra best?
Andorra often deserves first consideration for:
- high-income digital founders and professionals;
- people who genuinely want to live close to Spain;
- families wanting geographic proximity to the Iberian Peninsula;
- business owners willing to create real Andorran activity;
- wealthy individuals seeking a stable low-rate personal tax environment;
- people who prefer not to rely on a temporary ten-year incentive.
N30 Global’s current Andorra tax-residency advisory uses exactly this approach: test the full structure rather than selling the destination.
Dubai / UAE: no personal income tax does not mean no tax anywhere
The UAE has the most distinct tax model of the three.
The UAE Government confirms that it does not levy a general income tax on individuals.
That can make salaries and personal investment income particularly attractive at personal level.
However, the introduction of Corporate Tax means Dubai should no longer be described as “0% on every person and every business”.
Natural persons conducting business
The Federal Tax Authority states that a natural person can become subject to Corporate Tax on UAE business activity where total turnover from the relevant business activities exceeds AED 1 million in the calendar year.
The following are excluded from that business-activity calculation:
- wages;
- personal investment income;
- real-estate investment income within the relevant rules.
Companies
Under the general Corporate Tax framework, taxable income up to AED 375,000 is taxed at 0%, with the excess generally taxed at 9%.
Free Zone rules can provide different treatment for qualifying income, but a Free Zone licence should never be presented as automatic 0% taxation.
What counts as UAE tax residence?
For domestic Tax Residency Certificate purposes, the FTA identifies several routes for natural persons, including:
- 183 days or more of presence;
- 90–182 days combined with legal residence and relevant UAE employment, business or permanent-home ties;
- or a test based on primary residence and centre of financial and personal interests.
For treaty certificates, the specific treaty requirements must also be considered.
A visa or Emirates ID therefore does not by itself prove that a former country such as Spain must accept that the individual has ceased to be resident there.
Who tends to fit Dubai best?
Dubai can be particularly compelling for:
- founders with international clients;
- investors with dividends and financial portfolios;
- highly mobile professionals who can genuinely live outside Europe;
- entrepreneurs combining personal residence with a UAE business structure;
- individuals who prioritise personal tax efficiency over proximity to Europe.
Comparison by income profile
| Income profile | Portugal | Andorra | Dubai / UAE |
|---|---|---|---|
| High salary | Potentially excellent under IFICI | Highly competitive at max 10% | Highly competitive with no general personal income tax |
| Freelancer / consultant | IFICI only where exact conditions fit | Strong where genuine local residence/activity exists | Strong, but natural-person Corporate Tax must be tested |
| International dividends | Can be attractive under IFICI depending on source/rules | Low-tax environment; source and treaty still matter | Very attractive at personal level; corporate structure still matters |
| Investment portfolio | Highly dependent on IFICI eligibility and income category | Low tax but not necessarily zero | Particularly attractive for personal investment income |
| Own business | Company + remuneration + possible IFICI | Can combine residence with genuine local business | Strong international platform; Corporate Tax must be modelled |
| Pension | IFICI does not generally exempt pension income | Andorran tax + treaty analysis | No local personal income tax, but source-country/treaty rules remain critical |
For pensions, nationality is not enough to answer the question. Public/social-security pensions, occupational pensions, private arrangements and public-service pensions can be allocated differently under treaties. The source country and legal nature of the payment must be identified first.
Portugal, Andorra or Dubai?
If you compare only headline rates, you can choose the wrong jurisdiction. Current residence, company structure, dividends, property, family, wealth and lifestyle can completely change the result. N30 Global’s International Tax Simulator helps identify which scenarios deserve serious analysis before you move.
Which one would we analyse first for six common profiles?
1. Spanish founder with a profitable company and family
If staying physically close to Spain is essential and the whole family can genuinely relocate, Andorra often deserves the first analysis.
Portugal can be stronger where EU continuity matters and IFICI fits. Dubai may beat both on personal tax but only if the family and business can genuinely relocate.
2. Highly qualified technology professional
Portugal can be the first candidate if the exact IFICI conditions are satisfied.
Without IFICI, the ranking can change completely.
3. Digital consultant earning €150,000–€300,000
Andorra can offer a strong balance of tax, proximity and operational reality.
Dubai can produce lower personal tax, but business Corporate Tax and the larger lifestyle move must be included.
Portugal depends heavily on IFICI eligibility.
4. Investor living mainly from dividends and a portfolio
Dubai is usually the first tax scenario to model.
Andorra may be a better overall fit for someone who values European proximity.
5. Wealthy family with children still at school in Spain
We would not select a country before analysing the family.
A formal residence in Andorra or Dubai can be weak if spouse, children, family home and daily life remain in Spain.
6. Retiree with international wealth
We would first identify the source and legal type of every pension, then property, investment income, wealth and succession objectives.
The old generic argument “Portugal NHR for retirees” is no longer a sound starting point for new cases.
Your company can change the answer completely
Three people can each earn €250,000 and need three different countries:
- an executive earning salary;
- a founder receiving dividends from a Spanish company;
- a consultant invoicing international clients personally.
The analysis needs to identify who earns the income, where work is performed, where a company is managed, withholding tax, Corporate Tax, treaties, social security and how funds reach the individual.
Family can matter more than the headline tax rate
A destination is only useful if it can become a real residence.
If someone obtains UAE residence while their spouse, children, family home, daily company management and substantial physical presence remain in Spain, the UAE’s lack of personal income tax may be irrelevant if Spain can still claim personal tax residence.
The same principle applies to Andorra and Portugal.
Which country would we test first by priority?
| Your main priority | First jurisdiction to test |
|---|---|
| Lowest possible personal taxation | Dubai / UAE |
| Low tax + maximum proximity to Spain | Andorra |
| Remain inside the EU | Portugal |
| Qualifying science/technology profile | Portugal / IFICI |
| Digital founder with family close to Spain | Andorra |
| Highly mobile international investor | Dubai |
| You cannot genuinely move family and activity | None yet |
N30 Global’s international tax-residency advisory starts from the individual rather than the country: current residence, business, income, wealth, family, banking and timing come before the jurisdiction.
Frequently asked questions
Which has the lowest personal taxes: Portugal, Andorra or Dubai?
For an individual whose income is not brought into UAE Corporate Tax as business activity, Dubai can provide the lowest local personal taxation because the UAE does not levy a general personal income tax. The real outcome still depends on source-country tax, companies and treaties.
Does Portugal still have NHR?
Not as a general regime for new arrivals. NHR was repealed from 1 January 2024, although existing and specific transitional cases remain. New cases should test IFICI instead.
Can anyone qualify for Portugal’s IFICI?
No. It requires prior non-residence and a qualifying activity, role or employer within the categories set by Portuguese law.
Does Andorra only require 90 days for tax residence?
That is not the general tax rule. Andorran tax law uses more than 183 days or the principal centre/base of activities or economic interests. Immigration categories can use different presence conditions.
What is Andorra’s maximum personal income tax rate?
The general maximum IRPF rate is 10%, subject to the applicable deductions and rules.
Is Dubai really 0% tax?
The UAE does not levy a general personal income tax, but business activities of natural persons can enter Corporate Tax above the applicable turnover threshold, and companies are subject to the UAE Corporate Tax framework.
Can I live in Spain and claim tax residence in Dubai or Andorra?
A residence should not be purely documentary. Spain applies its own residence tests based on presence, economic interests and family. Treaty rules may be required where two states claim residence.
Which is best for a retiree?
There is no universal answer. The source country and legal nature of each pension must be identified first because social-security, occupational, private and public-service pensions can receive different treaty treatment.
Conclusion: the best jurisdiction is not the one with the lowest headline rate
Portugal offers EU continuity and can be exceptional for someone who genuinely fits IFICI.
Andorra combines low personal tax with proximity to Spain and a stable ordinary tax system, but requires a genuine move and the appropriate immigration route.
Dubai can deliver the strongest personal-tax outcome for many international profiles, but it requires a larger geographical relocation and proper coordination with business Corporate Tax.
The decision should model income, companies, dividends, investments, family, wealth, the country being left and the next five or ten years.
N30 Global’s International Tax Tailoring approach is designed for exactly that question: not where tax is lowest in theory, but where your personal, corporate and wealth structure can work coherently in practice.
