When should a high-income IT consultant start thinking about their tax residency?
Summary
Introduction
The question almost always arises in the same order. An IT consultant sees their revenue steadily increasing, notices that their tax and social security contributions are following the same trend, and then wonders at what precise moment they should seriously examine their country of residence. The answer never lies in a single amount; it lies in a combination of thresholds and signals that few professionals know how to interpret in time.
However, there are some fairly clear guidelines. Below a certain income level, the actual cost of expatriation outweighs the expected tax benefits, and the question is no longer worth asking. Above that level, the gap becomes so wide that doing nothing becomes a decision in its own right , with its own financial consequences.
This article isn't trying to sell you a destination. It answers the question posed: when should you start thinking about it, and how do you know when the time is right? We'll distinguish between the relevance threshold, the tipping point, and the urgency threshold —three concepts often confused by high-earning consultants.
Finally, we will see that thinking too late sometimes costs more than not thinking at all, especially when exit tax and unrealized capital gains are factored in. Timing is just as important as the destination, and it remains the most neglected aspect of the decision-making process .
Why the question never boils down to a single amount
A consultant who bills €90,000 with three French clients, an outstanding mortgage, and school-aged children is not in the same situation as a single DevOps engineer who bills the same amount to European clients. The former has a firmly established center of life , while the latter enjoys genuine mobility. The amount is the same, but the answer is not.
This is why comparison charts found online are often misleading. They present nominal rates without ever factoring in the cost of living, the need for physical presence, recurring overhead costs, or the loss of social security coverage. Expatriation should be judged on a net balance after all expenses , not on a stated percentage.
The right way to approach the problem is to think in terms of trajectory rather than snapshot. A consultant who progresses by 30% per year will reach a level of income within eighteen months where the trade-off becomes obvious, and it is today that they must begin preparing the ground . A consultant who has been stable at the same level for five years reasons differently.
We've already explored this logic from another angle, explaining why a fully remote IT consultant should consult their country of residence . The question of when to investigate this is a direct extension of that, and it calls for quantifiable data rather than intuition.
Income thresholds that change the nature of the problem
Three distinct income levels emerge in the cases we handle. These are not absolute rules, but they accurately describe the point at which the analysis moves beyond purely theoretical considerations. Each level calls for a different approach , and confusing these levels leads to poorly calibrated decisions.
Between 80,000 and 120,000 euros: the question remains premature.
At this level, the tax difference between France and a low-tax jurisdiction does exist, but it is largely offset by the costs of setting up and maintaining a structure abroad. Local accounting, registered office address, travel, private health insurance, and double filing ultimately negate a significant portion of the savings .
This doesn't mean you should do nothing. On the contrary, it's the ideal time to avoid accumulating difficult-to-undo ties later, such as a primary residence purchased with a mortgage or shares that will trigger exit tax. Early planning costs little and preserves all future options .
Between 120,000 and 250,000 euros: the range where arbitrage becomes real
It is in this tax bracket that the majority of IT consultants cross the threshold of profitability. The combined tax and social security burden becomes significant enough that the annual difference compared to a lower-tax jurisdiction far exceeds the fixed costs of establishing a presence. The choice ceases to be theoretical and becomes a calculation to be made over a three-year period .
The difficulty then shifts to feasibility. Is it really possible to spend more than half the year elsewhere, relocate one's home, and retain French clients without establishing a permanent establishment in France? It is these operational constraints, and not the stated tax rate, that ultimately differentiate between a transfer of tax residence to Andorra and a project geared towards Georgia and its small business regime .
Above 250,000 euros: the cost of inaction dominates
At this stage, each year that passes without considering the issue represents a significant sum, and the logic is completely reversed. The question is no longer whether expatriation is worth the cost, but why it wouldn't be appropriate. Remaining in France becomes a position that must be justified rather than a default choice.
This is also the point at which structuring takes precedence over mere residency. A local operating company, a credible economic foundation, and documented governance become essential, as a project of this scale naturally attracts the attention of the authorities. The quality of the structure then matters as much as the chosen purpose .
The three criteria that determine your tax residence
Before discussing thresholds, it's essential to understand the legal basis for determining your tax residency. Article 4 B of the French General Tax Code outlines three alternative criteria, and only one is required to establish you as a French resident. Therefore, tax residency isn't determined by declaration; it's established through a combination of factors.
The first criterion is your home, meaning the place where your immediate family usually lives, regardless of your own travels. The second is your primary residence, measured in days spent there. The third combines your main professional activity and the center of your economic interests , often the most complex for an IT consultant.
The 183-day rule is only one criterion among three
Many consultants think only in terms of days spent in France, assuming that if they spend less than 183 days there, they automatically fall outside the scope of the regulations. This is incorrect. A consultant who spends one hundred days in France but whose family lives there and whose entire income comes from French clients remains highly susceptible to reclassification .
When two states simultaneously claim your residence, the bilateral tax treaty applies a series of successive criteria: permanent home, center of vital interests, habitual residence, and then nationality. This mechanism resolves mixed situations and explains why a partial departure offers no protection .
The six signs that indicate the time has come
Beyond the numerical thresholds, certain concrete signals mark the entry into the arbitration zone. They are not significant in isolation, but their accumulation constitutes a reliable indicator that the decision-making process can no longer be postponed for another year.
The first indicator is the stabilization of high revenue over three consecutive fiscal years, which rules out the possibility of a temporary spike. The second is the geographical diversification of your client portfolio, which makes your business less dependent on a single market. The third is the absence of significant family or property ties, which would make relocating a business a realistic option .
The fourth warning sign relates to the entirely digital nature of the deliverables, typical of development, cloud, or cybersecurity projects. The fifth appears when you plan to build significant investment assets, at which point the taxation of dividends and capital gains becomes more important than that of business income . The sixth is simpler: you're already dedicating time to the issue without a structured approach.
Three signals combined are sufficient to justify a structured study. Five signals combined generally mean that you should have launched this study twelve to eighteen months earlier, as the administrative delays of most jurisdictions require real anticipation .
Comparison: How income levels change depending on the jurisdiction
The table below cross-references the public legal frameworks of several jurisdictions with the IT consultant profile to which they best correspond. It does not rank the countries; it shows that each income level calls for a different response .
Jurisdiction | Income tax | Corporate tax | Expected attendance | IT consultant profile |
United Arab Emirates | No personal income tax | 9% above AED 375,000 | Visa renewal and regular presence | High income and high mobility |
Cyprus | Progressive scale up to 35% | 12.5% | 60 days possible under certain conditions | European consultant with EU clients |
Malta | Progressive scale, specific schemes | 35% nominal with credit mechanism | Expected actual stay | Holding company structuring |
MAURITIUS | 15%, 20% on the upper bracket | 15% with partial schemes | 183 days | Clients in Africa and Asia |
Andorra | Maximum 10% | 10% | 183 days | Consultant wishing to remain close to France |
Portugal | Tax brackets up to 48%, IFICI regime at 20% | 21% | 183 days | Qualified professional seeking a European executive position |
Georgia | 20%, small business scheme at 1% of turnover | 15% with deferral on distribution | Favorable territory | Intermediate income in the testing phase |
This table primarily illustrates that a consultant charging €130,000 and a consultant charging €400,000 should not be looking at the same things. The former will prioritize administrative simplicity and entry cost, while the latter will focus on legal soundness and structuring capabilities. This logic applies equally to a transfer of tax residence to Portugal and to a project aimed at transferring tax residence to the Bahamas .
Thinking too early or too late, two symmetrical mistakes
Planning too early leads to setting up an oversized structure for revenues that don't yet justify it. The consultant pays fixed costs, complicates their accounting, and weakens their relationship with clients who don't understand foreign invoicing. The tax benefit exists, but it's eaten up by the operational complexity .
Waiting too long to decide has the opposite and more costly effect. Ties have multiplied, assets have accumulated in France, unrealized capital gains have grown, and leaving becomes a complex undertaking. What should have been a simple decision to establish residency becomes a multi-year wealth management project .
The trap of leaving decided in December
Every year-end, consultants discover the amount of their tax liability and decide to leave within weeks. This haste almost always results in poor cases: visas obtained in a rush, lack of substance, continued availability of accommodation in France, and poorly documented termination of employment. The tax authorities interpret this type of departure as a contrived scheme .
A well-planned expatriation requires preparation over the preceding fiscal year, not just the last quarter. Obtaining a residency permit, opening local bank accounts, reorganizing your invoicing, and informing your clients takes time. A twelve-month project presents a far more defensible case than a last-minute departure.
Exit tax, unrealized capital gains and tax calendar
The exit tax represents the most tangible timing constraint for an IT consultant who has become a shareholder in their own company. It applies to unrealized capital gains on shares when their value exceeds the legal threshold, provided the individual has been a French resident for six of the last ten years. It transforms the timing of departure into a key financial factor .
A consultant whose company is currently undervalued but accumulates cash each year will see that value grow automatically. Leaving before the valuation reaches certain thresholds simplifies the process considerably, while waiting three more years can completely change the equation .
The civil calendar is equally important. Tax residency is assessed annually, and a mid-year departure creates a mixed year requiring meticulous reporting. Jurisdictions with strong territorial boundaries, such as those covered by tax residency transfers to Panama , also necessitate determining the geographical origin of income from the very first year.
Make the decision at the right time
A well-conducted residency decision begins with an honest assessment: actual and projected income, geographic distribution of clients, household composition, assets held, and non-negotiable personal constraints. This initial snapshot typically eliminates half of the jurisdictions under consideration within a few hours.
Twelve to eighteen months, the realistic timeframe
Between the initial feasibility study and full implementation, an average of twelve to eighteen months is required. This timeframe encompasses comparative analysis, legal validation, immigration procedures, establishing the local structure, and contractual reorganization with clients. Anticipating this timeframe avoids making decisions under time constraints .
The final, often underestimated step is to document the break with France: lease termination or letting of the property, transfer of accounts, change of address with relevant organizations, declaration of departure, and clarity regarding the actual place of business. This traceability is your best protection in the event of an audit .
Testimonial: A cloud architect with a turnover of 240,000 euros
A freelance cloud architect in his forties, with no dependent children, contacted us after three years of stable revenues of around €240,000. He worked for four major clients, two of them outside France, and had no real estate ties . His question was exactly the one posed in this article: was it already too late, or still too early?
The study showed that he was in a favorable position. His company had been accumulating cash for only two years, the valuation remained below exit tax thresholds, and his international clientele made a European expansion a credible option. Waiting two more fiscal years, however, would have significantly complicated the situation .
He carried out his project over fourteen months, gradually rebilling from his new structure while retaining his four clients. Eighteen months after its implementation, he primarily describes the benefit of increased transparency: he knows exactly what he is paying for, where, and why. The tax savings were important, but the legal clarity weighed just as heavily in his satisfaction.
Frequently Asked Questions
Is there an official income threshold from which one must leave?
No, there is no legal threshold that triggers expatriation. In practice, the decision becomes truly significant above €120,000 in annual income, and the question of the cost of inaction becomes paramount above €250,000. These are guidelines, not hard and fast rules .
Can I keep my French clients after I leave?
Yes, in the vast majority of cases. The key point is to be vigilant regarding the concept of a permanent establishment: if you maintain an office, staff, or a regular presence in France, the tax authorities may consider that a portion of the profit remains taxable there. Contractual documentation plays a crucial role .
Is it mandatory to spend 183 days outside of France?
The number of days spent in France is only one of three criteria used by the French General Tax Code. A consultant can spend fewer than 183 days in France and still remain a French resident if their home or center of economic interests remains there. Therefore, several factors must be considered simultaneously .
What happens if I leave and then come back two years later?
A return is perfectly possible, but a quick trip weakens the credibility of the initial departure and may warrant a retrospective review. Furthermore, the deferral mechanisms linked to the exit tax have their own time limits. A residency plan should be considered over a period of several years .
Does my activity on freelance platforms change anything?
Platforms generally accept service providers based abroad, but each imposes its own requirements regarding invoicing, VAT numbers, and identity verification. It's wise to check these requirements before departure rather than after, as they can influence your choice of jurisdiction .
How can I know if my situation warrants a study?
If you exhibit three of the six indicators described above and your income consistently exceeds €120,000, a comparative study provides a useful numerical answer, even if it concludes that you should remain in France. Coreway Consulting conducts this analysis as a customized study upon request .
Conclusion
The right time to think about your tax residency always comes sooner than you think. It doesn't coincide with the moment when taxation becomes painful, but with the moment when your income trajectory becomes clear and your anchors are still easy to shift .
Three key ideas summarize this article. The real arbitrage zone begins around €120,000 in revenue, the accumulation of signals is more important than a single amount, and the exit tax timing requires anticipation of twelve to eighteen months. Each case then generates its own response .
You're a high-earning IT consultant and you're wondering if it's time to review your tax residency. You can request a personalized study from Coreway Consulting to compare your situation with the ten jurisdictions we support.
