Getting married (or entering a partnership) in Switzerland as a foreigner: procedures, deadlines and tax 2026 Guide

Who may marry in Switzerland as a foreigner?

Three conditions are enough in theory: being 18 years old, having capacity of judgement, and being bound neither by an existing marriage nor by an existing registered partnership. To these is added the absence of a prohibited family relationship. These rules appear in articles 94 and following of the Swiss Civil Code and apply in the same way to Swiss citizens and foreigners, to opposite-sex and same-sex couples since marriage for all came into force on 1 July 2022.

The fourth condition applies to foreigners only, and it is the one that blocks the most files.

Lawful residence: the condition that is not negotiable

Since 1 January 2011, article 98 paragraph 4 of the Civil Code requires fiancés who do not hold Swiss nationality to prove that their stay in Switzerland is lawful during the preparatory procedure. In practice, the civil registrar asks for a valid residence permit, a valid visa or a confirmation from the cantonal migration authority. Without lawful residence, the registrar refuses to celebrate the marriage — and reports the situation to the competent immigration authority.

The rule was introduced to fight marriages of convenience. It has a side effect worth knowing: someone whose permit expires during the six months of the procedure must make sure it is renewed, or the file will be suspended a few weeks before the booked date. Our guide to Swiss residence and work permits B, C, G and L covers the validity and renewal conditions of each permit.

Do you have to live in Switzerland to marry there?

No. This is a persistent misconception, particularly among French-Swiss couples in the Lake Geneva region. A couple where neither partner is domiciled in Switzerland can perfectly well marry there: they file their request with the civil registry office of the municipality where the celebration is planned, or go through the competent Swiss representation abroad when one of the fiancés is Swiss and lives outside the country.

The general rule remains that the request is filed with the civil registry office of the domicile of one of the two fiancés. The marriage can then be celebrated in another canton: the office that ran the procedure issues an authorisation to celebrate the marriage, which the office of the chosen place accepts. That mechanism is what allows a couple to run the procedure in Nyon and marry in Geneva, or the other way round.

How does the preparatory marriage procedure work?

The preparatory procedure is mandatory and unfolds in four stages: filing the request, review of the file by the civil registrar, declaration by the fiancés on the conditions of marriage, then notification of closure which opens a three-month window to celebrate. No step is optional, and no ceremony date is final until the procedure is closed.

Step 1 — Filing the request

Both fiancés jointly file a request to carry out the preparatory procedure with the competent civil registry office, together with the documents listed in the next section. Many offices, in Geneva and the canton of Vaud in particular, now offer digital submission or pre-checking of documents before the in-person appointment — a real time saver for an international file, which avoids discovering on the spot that a birth certificate is more than six months old.

Step 2 — Review of the file

The civil registrar checks that the conditions of marriage are met and that no impediment exists: age, capacity of judgement, absence of an undissolved prior marriage or partnership, absence of a prohibited family relationship, and lawful residence for foreign fiancés. This is the stage that triggers, where applicable, an authentication procedure for foreign documents: substantive review of the certificates, verification with the embassy, legalisation. It is also the longest and least predictable stage.

Step 3 — Declaration by the fiancés

Both fiancés appear in person before the civil registrar and declare that the conditions of marriage are met and that the data in the file is accurate. This declaration is signed; it is legally binding. Where one of the fiancés cannot travel, the registrar may visit them or delegate the reception of the declaration to another office.

Step 4 — Closure and the three-month window

The registrar notifies the fiancés that the procedure is closed. From that notification, the marriage must be celebrated within three months, in accordance with article 100 of the Civil Code. After that, the authorisation lapses and the procedure must start again from scratch, with new documents and new fees. The canton of Vaud also points out that celebrating in another canton requires an authorisation to celebrate the marriage accepted by the office of the chosen place.

Which documents must a foreign fiancé provide?

The list varies with nationality and with the country that issued the certificates, but a core set always comes back: a recent birth certificate, valid proof of identity, a residence certificate, a document on current civil status, and proof of lawful residence in Switzerland. For a fiancé domiciled abroad, a certificate of capacity to marry issued by their national authorities is usually added.

Apostille, legalisation, translation: the three filters

A foreign document is not accepted as it is. It has to pass up to three successive filters. The apostille, provided for by the 1961 Hague Convention, is enough for states parties — that includes France, Italy, Spain, Portugal and Germany. For other countries, a chain legalisation is required, going through the local authorities and then the Swiss representation on site. Finally comes translation by a sworn translator when the certificate is not written in a Swiss national language.

This path explains both the delays and the amounts. The civil registry office of the canton of Geneva states, in its page on the preparatory marriage procedure, that authenticating foreign documents "may take several months" and asks for an advance payment of 300 to 2,000 CHF per person depending on the country. A French-Swiss couple will usually get away with a few dozen francs of apostilles; a couple where one fiancé comes from a state outside the Hague Convention must set aside several hundred francs and six extra months.

How long does a civil wedding in Switzerland take and what does it cost?

Short answer: 6 to 8 weeks and 300 to 400 CHF for a simple file; six months and 800 to 2,500 CHF as soon as a certificate has to come from a state outside the Hague Convention. The gap does not come from the wedding itself, whose tariff is regulated, but from the processing of foreign documents.

Can you still enter a civil partnership in Switzerland in 2026?

No, not in the federal sense of the term, and this is probably the most misunderstood question on the subject. Since marriage for all came into force on 1 July 2022, no new registered partnership can be concluded in Switzerland. The registered partnership, reserved until then to same-sex couples, was closed the very day marriage was opened to them.

The Federal Office of Justice confirms this in its FAQ on marriage and marriage for all: partnerships concluded before that date remain valid, and the couples concerned may keep them as they are or convert them into a marriage through a declaration of conversion before the civil registry. Foreign partnerships concluded before 1 July 2022 are convertible if they are recognised as equivalent to the Swiss registered partnership — that is the case of the Italian unione civile or the German Lebenspartnerschaft. The French PACS, however, is not convertible: PACS partners who want the status of spouses must marry.

The four options that remain today

For a cross-border couple, the practical consequence is clear: if the goal is real legal protection in Switzerland — right of residence for the spouse, inheritance, pension, joint taxation — marriage remains the only route today. The Geneva cantonal partnership is largely symbolic in dealings with the administration; a PACS concluded at the French consulate produces its effects under French law but opens no right of residence in Switzerland.

What does marriage change for the foreign spouse's residence permit?

A great deal, and immediately. The foreign spouse of a Swiss citizen is entitled to be granted a residence permit, and to have it extended, provided they live in a shared household with them: that is article 42 of the Federal Act on Foreign Nationals and Integration. This right takes the form of a B permit, generally issued for one year and renewable, and not of an automatic naturalisation — marriage does not confer Swiss nationality.

Facilitated naturalisation: three years of marriage, five years in Switzerland

Marriage opens a faster route to the Swiss passport, but it remains demanding. The foreign spouse of a Swiss citizen may apply for facilitated naturalisation if they have lived three years in marital union with them and have resided five years in Switzerland in total, including the year preceding the application without interruption. For a spouse living abroad, the condition rises to six years of marital union together with close ties to Switzerland. The integration criteria — language, respect for the legal order, participation in economic life — apply in every case, and the federal fee is 900 CHF.

Our guide to Swiss naturalisation, steps and requirements covers the full path, including the ordinary route, and what happens to years spent on a G permit — they do not count.

How does marriage change taxation in Switzerland?

Two rules, and they do not work the same way. For a resident taxed under the ordinary regime, marriage takes effect over the whole calendar year: spouses living in a shared household are taxed jointly for the entire tax period during which they married. A couple married on 20 December 2026 therefore files a joint return for the whole of 2026. For a taxpayer taxed at source, by contrast, the change of bracket takes effect from the beginning of the following month. This asymmetry is the source of most unpleasant surprises.

Joint taxation and the "marriage penalty"

Under ordinary taxation, the income and wealth of both spouses are added together and then subject to a single rate scale. Because Swiss tax is progressive, that pooling can push the household into a higher band: this is the well-known marriage penalty, which mainly hits couples where both partners earn comparable incomes. An unmarried couple on the same incomes files two separate returns and stays in lower bands.

The effects people forget to count

Marriage does not only change the rate scale. It also changes the matrimonial property regime: absent a marriage contract signed before a notary, spouses fall under participation in acquired property, which means each keeps ownership of their assets but the acquisitions built up during the marriage are shared in halves on dissolution. It opens a right to a surviving spouse's pension in the AHV/AVS and in occupational pension provision, whereas a cohabiting partner is only entitled if the pension fund regulations provide for it and a declaration has been filed. Finally, it makes second-pillar assets accumulated during the marriage divisible in the event of divorce — a point developed in our guide to occupational pension provision.

On names, the Swiss principle is that each spouse keeps their maiden name. Spouses may however declare, during the preparatory procedure, that they wish to bear the maiden name of one of them as a common family name. That choice is made before the ceremony, not after: it has to be considered when filing the request.

Cross-border workers: when must you report your marriage to the Swiss authorities?

Right away, and through your employer. For a cross-border worker taxed at source in Switzerland, the change of bracket takes effect from the first day of the month following the marriage, and in Geneva the taxpayer has 14 days from the change in family situation to hand their employer an updated withholding tax declaration, together with the marriage certificate. It is the employer who then applies the new bracket on the payslip.

The rule is federal: any change leading to a different bracket — marriage, birth, separation, divorce, start or end of the spouse's gainful activity — must be taken into account for withholding tax from the beginning of the month following the change.

Married in France or abroad: what has to be reported in Switzerland?

This is the most frequent scenario among cross-border workers: the ceremony takes place in France, Italy, Portugal or elsewhere, and nothing happens automatically on the Swiss side. Two strands have to be distinguished, and they do not concern the same people.

The tax strand concerns every cross-border worker taxed at source, whatever the country of celebration. The process is the same as for a wedding celebrated in Switzerland: complete a new withholding tax declaration — the online version is the one the Geneva administration recommends —, sign it and hand it to your employer, not to the tax administration, together with the marriage certificate. A French certificate is accepted as it is, without translation or apostille, since it does not enter the Swiss civil status register. The 14-day deadline runs from the date of the marriage, not from the date you get back from your honeymoon.

The civil status strand concerns only some couples. A marriage celebrated abroad is not automatically recognised in Switzerland: it must be reported to the Swiss representation in the country of celebration, which authenticates the documents and then forwards the file to the cantonal civil status supervisory authority, which rules on recognition and enters it in the register. The procedure takes several months. It applies to Swiss citizens, whose competent authority is that of their canton of origin, and to foreign nationals domiciled in Switzerland for whom a civil status event is already recorded in the country. The canton of Vaud sets out the steps in its page on reporting a civil status event that occurred abroad.

The case of the eight cantons under the 1983 agreement

Not all cross-border workers are affected by this mechanism. The France-Switzerland agreement of 11 April 1983 provides that the salaries of cross-border workers employed in the cantons of Bern, Solothurn, Basel-Stadt, Basel-Landschaft, Vaud, Valais, Neuchâtel and Jura are taxable only in the state of residence, against a financial compensation of 4.5% of the gross payroll paid to the other state. A cross-border worker in Lausanne or Sion who hands their employer the 2041-AS tax residence certificate every year is therefore not taxed at source in Switzerland: their marriage has no Swiss bracket to change.

Geneva is not a party to that agreement. Cross-border workers employed there are taxed at source in Switzerland, and they are the ones who must report their marriage within 14 days. Our guide to cross-border worker taxes in Switzerland maps this dividing line canton by canton.

What traps await a cross-border worker who marries mid-year?

Three main traps, all linked to the fact that marriage changes the calculation basis of the household and not only that of the individual. None of them is flagged spontaneously by the administration.

Trap 1 — Losing quasi-resident status

Quasi-resident status allows a cross-border worker taxed at source to request subsequent ordinary taxation and claim deductions that would otherwise be out of reach — actual expenses, second-pillar buy-ins, loan interest. The condition is that at least 90% of gross worldwide income is taxable in Switzerland. As the Geneva tax administration explains in its page on determining quasi-resident status, the worldwide income of both spouses is added together before the ratio is calculated for a married couple.

The direct consequence: a single cross-border worker who met the criterion easily can lose it the day they marry someone working in France. With a Geneva salary of 110,000 CHF and a spouse on 35,000 EUR in France, the Swiss share falls below 90% and the status is lost. Our guide to quasi-resident status in Switzerland details the calculation, and our guide to cross-border worker tax deductions lists what remains deductible without that status.

Trap 2 — Bracket C and the spouse's notional income

When the spouse works abroad, the Swiss employer must apply the "dual activity" bracket taking that spouse's income into account. Since the employer does not know it, they determine the tax rate on the basis of a notional income calculated from statistical data. That theoretical income can exceed the spouse's real income — in which case the rate applied is too high for the whole year, and the only way to recover the overpayment is a correction request.

Trap 3 — The French calendar, which does not follow the Swiss one

On the French side, the year of the marriage is in principle subject to joint taxation covering the entire year, with the possibility of an irrevocable option for separate taxation, available only for the year of the marriage or PACS. That option is worth simulating: depending on the income gap between spouses and on the double taxation relief method applicable to the canton of employment, it can be favourable or costly. In parallel, the marriage must be reported within 60 days through the "Gérer mon prélèvement à la source" service so the withholding rate is adjusted without waiting for the following year's return.

One last point of vigilance concerns family allowances when the couple has or is expecting children: marriage changes the household composition, and the order of priority between the Swiss and French systems depends on where each parent works. Our guide to family allowances, Switzerland versus France, for cross-border workers covers the priority rule and the differential supplement mechanism.

How do you organise the money side of a cross-border wedding?

An international wedding has one feature common to every file we see: the spending is in Swiss francs, the income is often in euros, and the deadlines fall before the ceremony. Advance payment for authentication, sworn translations, civil registry fees, deposit for the reception venue: between filing the file and the big day, a cross-border couple easily pays 1,000 to 3,000 CHF in administrative and logistical costs in Switzerland.

The ibani scale is degressive: 0.40% up to 10,000 CHF, 0.35% from 10,000 to 50,000 CHF, 0.30% from 50,000 to 100,000 CHF, 0.20% from 100,000 to 250,000 CHF, then 0.15% above. No account opening, account maintenance or transfer fees are added. You can estimate the exact amount you would receive with our currency converter.

A personal Swiss IBAN, before and after the ceremony

A free personal Swiss IBAN lets you receive euros, convert at the real market rate at the moment of your choosing, then settle civil registry fees, translations and Swiss suppliers in francs — including by QR-bill, the Swiss standard format that not every foreign account handles correctly. ibani is a Swiss financial intermediary based in Geneva, not a bank: the aim is not to replace a local account, but to bridge euros and francs.

That usefulness does not stop on the wedding day. A mixed couple manages two currencies for the long run: a salary in francs, rent or a loan in euros, health insurance premiums and tax instalments in francs. Our guides on moving to Switzerland and on the first 30 administrative days as an expat set out the order of the steps when the wedding comes with a relocation, and our dedicated cross-border workers page explains how it works day to day.

Frequently Asked Questions

Can a foreigner get married in Switzerland without a residence permit?

No. Since 1 January 2011, article 98 paragraph 4 of the Swiss Civil Code requires fiancés who do not hold Swiss nationality to prove that their stay in Switzerland is lawful during the preparatory procedure. A valid residence permit, a valid visa or a confirmation from the migration authority is enough; without lawful residence, the civil registrar refuses to celebrate the marriage and reports the situation to the competent immigration authority. A couple where neither partner is domiciled in Switzerland, for instance two residents of France, can nevertheless marry in Switzerland without any problem: they do not need to live there, only to enter the country lawfully, and they file their request with the civil registry office of the chosen place of celebration or with the Swiss representation abroad. Our guide to B, C, G and L permits covers the documents concerned.

How long does the marriage procedure take in Switzerland for a foreign couple?

Allow 6 to 8 weeks for a straightforward preparatory procedure, and several months as soon as a foreign document has to be authenticated. The apostille, legalisation by the Swiss representation and translation by a sworn translator add two to six months depending on the country of origin, and in those cases the civil registry office asks for an advance payment of 300 to 2,000 CHF per person. Once the procedure is closed, the registrar notifies the couple: the marriage must then be celebrated within three months of that notification, otherwise the whole procedure has to start again. The practical rule is to file six months before the target date, and nine to twelve months if certificates have to come from a third country.

Can you still enter a civil partnership in Switzerland in 2026?

Not the federal registered partnership: since marriage for all came into force on 1 July 2022, no new registered partnership can be concluded in Switzerland. Couples who entered one before that date may keep it or convert it into a marriage through a declaration of conversion. There is no federal PACS either at this stage: the Legal Affairs Committee of the Council of States opened a consultation from 27 May to 17 September 2026 on a civil solidarity pact modelled on the French one, which would have no effect on civil status, name, filiation or taxation. Three options remain today: the Geneva cantonal partnership, declared at the civil registry since 2001, the Neuchâtel partnership concluded before a notary since 2004, both with effects limited to cantonal public law, and the French PACS, which two people of whom at least one is French and who live in Switzerland can conclude at the French consulate general in Geneva or Zurich.

When must a cross-border worker report a marriage to the Swiss tax authorities?

Straight away, and in any case without waiting for the end of the year. In Geneva, a cross-border worker taxed at source has 14 days from any change in family situation to hand their employer an updated withholding tax declaration together with the marriage certificate. This also applies when the marriage took place in France or another country: the form goes to the employer, never directly to the tax administration, and a French marriage certificate is accepted without translation or apostille. The employer then applies the new bracket from the beginning of the month following the marriage: a wedding celebrated on 15 June moves the file from the single to the married bracket on 1 July, not on the following 1 January. A marriage reported six months late means six months of withholding calculated on the wrong bracket, with a correction to be claimed before 31 March of the following year. This obligation does not concern cross-border workers in the eight cantons covered by the France-Switzerland agreement of 11 April 1983 — Bern, Solothurn, Basel-Stadt, Basel-Landschaft, Vaud, Valais, Neuchâtel and Jura — who are taxed in France upon presentation of the tax residence certificate and therefore have no Swiss bracket to adjust. Our guide to cross-border worker taxes covers this split.

How much does a civil wedding in Switzerland cost when one partner is a foreigner?

The civil wedding itself costs between 300 and 400 CHF in most cantons: in Geneva, opening and reviewing the preparatory procedure costs 150 CHF, to which are added around 75 CHF for a celebration in the official room on a weekday, a surcharge when the ceremony takes place on a Saturday or in a special venue, and around fifty francs for the family record book. The real expense for an international couple lies elsewhere: authenticating foreign documents, for which civil registry offices ask for an advance payment of 300 to 2,000 CHF per person depending on the country, plus apostilles and sworn translations. A revision of the federal fees put out for consultation in June 2026 would add at least 100 CHF to the bill and raise a celebration outside official premises from 50 to 200 CHF; it is not yet in force.
