France-Paraguay Tax Treaty: Avoiding Double Taxation
In short: there is no tax treaty between France and Paraguay — and contrary to popular belief, this is rather good news. As Paraguay applies territorial taxation (0% on foreign income), double taxation is naturally avoided: each country only taxes income generated on its own territory.
When expatriating to Paraguay for tax reasons, one question systematically arises: do I risk paying taxes in both countries at the same time? Double taxation is the nightmare of any expat, and rightly so — it can turn a tax optimization project into a financial nightmare if not properly anticipated.
The tax relationship between France and Paraguay is a technical but essential subject to master. Why is the absence of a treaty not a problem? How can double taxation be practically avoided? What are the reporting obligations on each side? This guide answers all these questions with clarity, so that your expatriation is fiscally irreproachable.
Is there a tax treaty between France and Paraguay?
The short answer: no
To date, there is no bilateral tax treaty between France and Paraguay aimed at avoiding double taxation. Contrary to what many believe, the absence of a treaty is not an obstacle — it is even, in the case of Paraguay, rather an advantage. Here's why.
Why the absence of a treaty is not a problem
A non-double taxation treaty is necessary when two countries claim the right to tax the same income. It then allocates the right to tax between the country of residence and the country of source. But in the case of Paraguay, the problem almost never arises, thanks to the principle of territoriality.
Paraguay only taxes income from Paraguayan sources. It does not seek to tax your French income. For its part, France no longer taxes you on your worldwide income once you are no longer a French tax resident. The result: each country taxes only what is due to it, without overlap. The absence of a treaty is therefore neutral — there is simply no double taxation to avoid in most cases.

How ending French tax residency works
Criteria for tax residency in France
According to Article 4B of the General Tax Code, you are a French tax resident if you meet at least one of the following criteria:
- Family home: your spouse and/or children live in France
- Main stay: you spend more than 183 days a year in France
- Professional activity: you carry out your main activity in France
- Centre of economic interests: your main investments, income, or assets are in France
To cease to be a French tax resident, you must ensure that none of these criteria are met. This is where preparation is crucial. If you move to Paraguay but your family remains in France, you keep your Parisian apartment, and your main bank accounts are French, the tax authorities may consider you are still a tax resident in France — regardless of what your Paraguayan cedula says.
The tax departure procedure
The transfer of tax residency outside France involves several specific administrative steps:
- Income tax declaration for the year of departure: you must file a declaration covering the period from January 1st to your departure date. This is an obligation, not an option.
- Notification to the tax office: inform your Individual Tax Department (SIP) in writing of your change of tax domicile abroad. Indicate your new address in Paraguay.
- Transition to non-resident status: once your departure is confirmed, any French-source income (rental income, capital gains) will be taxed under the non-resident regime, managed by the Non-Resident Individual Tax Department (SIPNR) in Noisy-le-Grand.
The date of departure: a key moment
The exact date of your departure determines the allocation of your income between the period of French residency and the period of non-residency. The earlier you leave in the year, the less taxable income you will have in France for that year. Some expatriates strategically plan their departure at the beginning of the calendar year to minimize their last French declaration.
Cases where double taxation can occur
Case 1: French rental income
If you keep a property in France that you rent out, the rents received remain taxable in France as French-source income, even after your departure. This is not double taxation because Paraguay does not tax this income (foreign source = outside the Paraguayan tax base). But you will indeed pay tax in France on these rents, at a minimum rate of 20% for non-residents, plus social security contributions.
Case 2: French real estate capital gains
If you sell a property in France after your expatriation, the capital gain is taxable in France. The rate for non-residents is 19% income tax, plus 17.2% social security contributions (with certain possible exemptions for the former main residence). Again, Paraguay will not tax this capital gain — it is French-source income.
Case 3: Public service pensions
As mentioned in our guide to retirement in Paraguay, pensions paid for public service employment in France generally remain taxable in France, unless you acquire Paraguayan nationality without retaining French nationality. For most retired civil servants, this pension will therefore be taxed in France — but not in Paraguay thanks to territoriality.
Case 4: Exit tax
If you hold shares in French companies representing at least 50% of the company's profits, or whose value exceeds €800,000, you are potentially liable for exit tax at the time of your transfer of domicile outside France. This tax on latent capital gains is subject to deferred payment (you don't pay immediately), but it must be declared. This is not double taxation in the strict sense — it is French taxation on a latent French gain — but it is a point to anticipate.
Case 5: Poorly managed transition period
The real risk of double taxation arises when the transition is poorly managed. If you declare yourself a Paraguayan tax resident but France continues to consider you a French tax resident (because you still meet one of the criteria of Article 4B), you could be taxed in both countries on the same income — without a treaty to resolve the conflict.
This is why a clean break with French tax residency is fundamental. The more traces of life you leave in France, the higher the risk of challenge.
The particular case of Belgium
Belgium-Paraguay Convention: also non-existent
As with France, there is no tax treaty between Belgium and Paraguay. The mechanism is similar: by leaving Belgium and establishing your tax residency in Paraguay, you cease to be taxed in Belgium on your worldwide income. Paraguay only taxes your local income. Overlap is naturally avoided.
Belgian specificities
Belgium applies tax residency criteria comparable to France (domicile, stay of more than 183 days, center of vital interests). Deregistration from the population register is an important step: it formalizes your departure and facilitates the recognition of your non-residency. Keep all documents proving your effective installation in Paraguay.
The particular case of Switzerland
A more regulated departure
Switzerland has its own rules for tax departure. You must deregister from your commune of residence, which ends your cantonal and communal tax liability. Federal direct tax also ceases as soon as you no longer have an economic attachment in Switzerland.
There is also no Switzerland-Paraguay tax treaty. But the same principle applies: Paraguayan territoriality prevents any double taxation on foreign-source income.
Evidence to establish to secure your tax position
Why evidence is essential
In the absence of a tax treaty, the reality of your situation determines where you are taxed. If the French tax authorities dispute your departure and consider that you are still a tax resident in France, it is up to you to prove otherwise. Here are the elements to gather and carefully keep:
Proof of life in Paraguay
- Paraguayan cedula (resident card)
- RUC (Paraguayan tax number)
- Lease or property title in Paraguay
- Utility bills (water, electricity, internet) in your name and Paraguayan address
- Bank statements from your Paraguayan bank account showing regular activity
- Medical bills, local subscriptions (gym, clubs, etc.)
- Consular registration with the French Embassy in Paraguay
Proof of break with France
- Lease termination or sale of property in France
- Departure declaration with the tax office
- Closure or conversion to non-resident account of your French bank accounts
- Termination of contracts (energy, telephone, insurance)
- Deletion from Social Security (or affiliation to the CFE)
- Flight tickets and passport stamps showing your actual presence in Paraguay
The evidence file: your best protection
Create a physical and digital file with all these documents, classified chronologically. In the event of a tax audit — which can occur even several years after your departure — this file will be your best ally. The more complete and consistent it is, the stronger your position.
Errors that expose you to double taxation
Keeping your home in France
Keeping an apartment or house in France — even if you only occupy it a few weeks a year — is one of the strongest signals for the tax authorities. It is interpreted as maintaining a "permanent home" in France, which may be enough to classify you as a French tax resident.
Not moving your economic center
If your main bank accounts, investments, income, and clients remain predominantly in France, the tax authorities may argue that your center of economic interests has not really changed. Gradually transfer your assets and activity to Paraguay.
Returning to France too often
Exceeding 183 days of presence in France in the year is an automatic trigger for tax residency. But even below this threshold, frequent and prolonged stays can be used as indicators by the administration. Keep a log of your travels and save your boarding passes.
Neglecting the departure declaration
Not filing your income tax declaration for the year of departure or not informing your tax office is an administrative error that can have serious consequences: penalties, reassessment, and above all, no official record of your change of residency.

Conclusion: no convention, no problem
The absence of a tax treaty between France and Paraguay worries many candidates for expatriation. Wrongly so. Thanks to the Paraguayan principle of territoriality, double taxation is naturally avoided in the vast majority of cases. Paraguay does not tax your French income. France no longer taxes you on your worldwide income once you are no longer a tax resident.
The real challenge is not the existence of a treaty — it is the quality of your tax departure. A clear, documented, and consistent break with your country of origin is the best protection against any risk of double taxation. It is a matter of preparation, not negotiation between states.
