What happens to your Luxembourg pension if you leave

You worked in Luxembourg for a few years. Now you are leaving — back home, onward to another European country, or further afield. The natural question is: what happens to the pension contributions you paid into CNAP? Do you get them back? Do they evaporate? Do you have to stay in Europe to see them? Do you have to be a EU national?

The short answer is that Luxembourg does not keep your money and does not refund it either. It keeps your contributions on file, and at retirement age it pays you a pension based on what you contributed — provided you meet two thresholds, and provided you live somewhere that has a legal pathway to receive it. For most leavers the pathway is straightforward. For a meaningful minority, it isn’t, and this article is written to make the difference clear.

The default rule: your LU years stay on file, and LU pays you at 65

When you stop contributing to the Luxembourg pension system — whether by leaving the country, changing jobs to a non-LU employer, or retiring — your Luxembourg contribution record does not close, reset, or expire. It sits with CNAP indefinitely, waiting for a pension application. You can apply decades later from another country and receive the pension you earned.

Two things have to be true at the point of application:

You qualified for a Luxembourg pension. The qualification test is the same as for any other claimant: you need a total of 120 months (ten years) of insurance, of which at least 12 months must be Luxembourg contributions. The 120 months can be aggregated across EU/EEA countries, Switzerland, the UK under the Withdrawal Agreement, and countries with which Luxembourg has a bilateral social security convention. See below for who and which.
There is a legal pathway to pay you abroad. Luxembourg pensions can be “exported” — paid to an account in another country — under EU Regulation 883/2004 for EU nationals and legally-resident third-country nationals, and under specific bilateral conventions otherwise. For anyone outside these frameworks, pension export is not automatic.

For most readers of this article, both conditions are met easily and the rest is procedural. The following sections walk through the common cases, then the edge cases, then what to do now.

Case 1: You’re leaving Luxembourg for another EU/EEA country, Switzerland, or the UK

This is the cleanest case. EU Regulation 883/2004 covers all 27 EU member states, plus Iceland, Liechtenstein and Norway via the EEA Agreement, and Switzerland via the EU–Swiss Agreement on Free Movement of Persons. The UK is covered for post-Brexit cross-border situations via the Withdrawal Agreement and the Trade and Cooperation Agreement.

Under 883/2004:

Your Luxembourg insurance months count for qualification purposes in your new country, and vice versa. If you had 6 LU years and then accrue 8 Dutch years, the Netherlands will recognise your 14 combined years when it tests whether you qualify for a Dutch pension. Luxembourg will do the same when it tests whether you qualify for a Luxembourg pension.
At retirement, each country pays you a partial pension based only on the years you contributed there. Luxembourg pays for your LU years. The Netherlands pays for your Dutch years. They do not merge into one pension.
You apply once, in your country of residence at the time of claiming. That institution forwards your file to every other country in which you have insured years, using the EESSI electronic exchange system.
Your Luxembourg pension is paid in euros into an account in your country of residence, every month, for life.

The one-year Luxembourg minimum still applies. If you worked in Luxembourg for less than 12 months, you will not receive a separate LU pension — but those months are not lost. They are counted by your new country for its qualification test. This is a rule that trips people up: “less than a year” means Luxembourg doesn’t cut you a cheque, it does not mean the contributions disappear.

Detailed mechanics of the 883/2004 cross-border pension system are covered in our frontalier article. If you left Luxembourg for France, Germany, or Belgium specifically, that article goes deeper on the country-by-country application process.

Case 2: You’re leaving for a country with a Luxembourg bilateral convention

Outside the EU/EEA/UK/CH bloc, Luxembourg has signed bilateral social security conventions with a list of individual countries. These conventions do for those countries roughly what 883/2004 does for the EU: mutual recognition of insurance periods for qualification, pro-rata calculation of pensions, and a legal basis for paying the Luxembourg pension into an account in the partner country.

The list, as published by Luxembourg’s Ministère de la Sécurité sociale, covers: Albania, Argentina, Bosnia and Herzegovina, Brazil, Canada (with a separate Quebec convention), Cape Verde, Chile, China, India, Japan, Morocco, Moldova, Montenegro, North Macedonia, the Philippines, Serbia, South Korea, Tunisia, Turkey, the United States, Uruguay, and the successor states of the former Yugoslavia.

The authoritative current list is published at secu.lu/conv-internationales/conventions-bilaterales. This list changes occasionally (new conventions are signed, old ones are renegotiated), so check the primary source before you make decisions based on it.

If you are leaving for a country on this list:

Your LU insurance months can still be aggregated with insurance in that country to clear Luxembourg’s 120-month threshold.
Your LU pension can still be paid abroad into an account in that country.
You apply through the equivalent pension institution in that country (or through CNAP directly), and the two institutions coordinate.
The conventions differ in detail — what counts as “insurance” under each country’s system is defined by the specific bilateral text, not by a single EU-wide rule. For most workers this is invisible; for edge cases (e.g. self-employment abroad, special regimes), it matters.

For US-specific readers, the Luxembourg–United States bilateral convention has been in force for decades and is the legal basis by which Luxembourgish pensions are routinely paid to retirees living in the US, and vice versa.

Case 3: You’re leaving for a country without a convention

If your destination is neither in the EU/EEA/UK/CH bloc nor on the bilateral conventions list, the situation is different and worth naming clearly.

Pension export is not automatic. Luxembourg does not have a general rule that CNAP pays pensions anywhere in the world. Countries without a bilateral convention — examples include Australia, Singapore, Hong Kong, the UAE, most of Sub-Saharan Africa, and much of Southeast Asia — fall outside the “third country with which Luxembourg has concluded an agreement” category. For these destinations, the legal basis for paying your LU pension into a local bank account is not guaranteed.

Your insurance months are still on file. Luxembourg does not close your record because you moved to Singapore. If you later move to a country that does have coverage (back to the EU, for instance, or to the US), you can apply from there. Your LU years are not erased.

Your nationality matters. Under EU Regulation 883/2004, EU nationals can export their Luxembourg pension to any EU/EEA/CH/UK country regardless of their current country of residence, as long as they are resident in one of those. For third-country nationals (non-EU citizens) who worked in Luxembourg, export rights depend on whether there is a convention between Luxembourg and their country of nationality (not necessarily their country of residence). This distinction catches people out and is worth taking seriously if it applies to you.

One fallback exists: back-purchase (“rachat”) of insurance periods. If you left a foreign pension regime not covered by any convention and you later return to Luxembourg and meet specific criteria — legal residence in Luxembourg, at least 12 months of compulsory LU insurance, under 65, not already entitled to a personal pension — you may be able to buy back retrospective insurance periods. This is a narrow mechanism and does not apply to most leavers, but it exists in Luxembourg law and is documented by CNAP.

What CNAP will and won’t do when you leave

It is worth being specific about what changes and what doesn’t at the moment of leaving:

What stays the same:

Your cumulative Luxembourg insurance months (your “carrière d’assurance”) remain on file indefinitely.
Your contribution amounts remain on file, revalued each year under the CNAP formula (fixed increase + proportional increase, then indexed), so your eventual pension reflects what you paid in at the time you paid it, adjusted for Luxembourg’s cost-of-living and revaluation factors up to the year of pension start.
Your eligibility for a Luxembourg pension at 65 is preserved.

What changes:

You stop accruing new Luxembourg insurance months (unless you elect voluntary continued insurance — see below).
You lose automatic access to Luxembourg health insurance as an employee; you are covered by the system of your new country of employment or residence.
You are no longer able to request a CNAP estimate under the same procedure as an active insured person — non-residents request estimates through the cross-border procedure, which goes through the contact institution in the country of residence.

What you can opt into (rarely right for leavers, but it exists):

Voluntary continued insurance (“assurance continuée”) lets some former LU insured persons keep contributing to the Luxembourg pension system from abroad under specific conditions. Eligibility is narrower than people assume — generally it requires a recent period of compulsory LU insurance and a specific application within defined deadlines. It is primarily of interest to people close to retirement who want to pad out specific thresholds (e.g. cross the 480-month line for early retirement at 60).

Caveat on voluntary continued insurance. It is not a “keep contributing forever while living abroad” option for most leavers. The rules are strict, the deadlines are short after leaving, and the arithmetic rarely favours it unless you have a specific reason — like being two years short of a 40-year compulsory total for early retirement. If you are considering it, speak to CNAP directly before committing.

A worked example: short-stint leaver

Consider someone who worked in Luxembourg for four years, from 2022 to 2026, then moved permanently to Portugal. Here is how their pension situation looks at 65:

4 Luxembourg years → clears the 12-month Luxembourg minimum → will receive a partial LU pension.
Their full career (say 35 years total across PT, LU, and one earlier country) → clears the 120-month aggregated EU minimum easily.
At 65, they apply once in Portugal. The Portuguese pension institution forwards their file to CNAP. CNAP calculates a Luxembourg pension based on the four Luxembourg years and their LU earnings history, revalued to the year of pension start. Portugal calculates its own pension. They receive both, monthly, in euros, into their Portuguese bank account.

The Luxembourg pension in this scenario is modest — four years of contributions, even at reasonable Luxembourg salaries, won’t produce a large figure. But it is real, it is indexed, it continues for life, and it continues to be paid to them regardless of whether they return to Luxembourg.

What to do now, as a leaver

If you are leaving Luxembourg or have recently left, the concrete steps are short:

Pull your CNAP career statement before you lose easy access. If you still have an active LuxTrust certificate, log in to MyGuichet.lu and download the statement now. You will need it decades later, and retrieving it as a non-resident is more painful than retrieving it while you still have LU digital identity.
Note your total insurance months. If the figure is under 12, you will not receive a separate LU pension — the months will count in your new country. If it is over 12, you will, eventually.
Check whether your destination is covered (EU/EEA/CH/UK, or on the bilateral conventions list). If yes, the default 883/2004 or bilateral pathway applies automatically when you claim. If no, be aware that pension export to your destination is not guaranteed.
Keep your records. Employment contracts, payslips from your LU years, the CNAP career statement, and your Luxembourg social security number. These aren’t strictly necessary — CNAP keeps its own records — but cross-border pension claims sometimes run into record-matching issues, especially for short stints, and having your own paper trail accelerates resolution.
Apply two to six months before your intended retirement date, through the contact institution in your country of residence at that time. Cross-border files take longer than domestic ones.

You do not need to notify CNAP that you are leaving. They will know — your employer stops declaring contributions, and your file transitions to dormant status automatically. There is no form to file and no deadline to meet on departure.

What this site’s calculator can and cannot do for you

The MyPensionPlan.lu calculator estimates your Luxembourg-only pension based on the years you contributed in Luxembourg. For a leaver, that is precisely the slice you care about: the amount CNAP will eventually pay you, separate from anything your new country of residence pays.

What we do not do:

Estimate your pension in your destination country. Those rules are different and would take a country-specific tool to model accurately.
Account for any bilateral-convention-specific quirks in the LU calculation. The standard CNAP formula applies regardless of destination; what changes is whether and how you can receive the payment, not how it is calculated.

If your career is mostly non-Luxembourg with a short LU stint, the calculator’s output will be a small number. That’s not a bug — it reflects the pro-rata reality of cross-border pensions.
