What to know for the Geneva return filed in 2026: the 31 March date, the price of an extension, the canton's deduction ceilings, the choice between GeTax and the online return (both in French), the TOU for B permit holders and cross-border workers. Plus a French to English glossary and how to prepare the file before opening GeTax.

Figures for the 2025 tax year (return filed in 2026), single taxpayer domiciled in the canton of Geneva, subject to change from one year to the next. This page informs; it replaces neither tax advice nor the AFC's GeTax guide, which exists in French only. Floxy is not a fiduciary or tax advisor and files nothing with the Geneva AFC.
The canton of Geneva gives you two official channels, both run by the cantonal tax administration (Administration fiscale cantonale, AFC). The first is GeTax 2025, the free software for Windows, OS X or Linux that declares 2025 income and wealth. The second is the online return, an e-démarches service with the same checks and printouts as GeTax and one advantage: it is pre-filled from last year's return if that one was transmitted over the internet, and receipts are attached as PDFs at the end.
Neither exists in English. The interface, the built-in help and the AFC's tax guide are in French, and we found no English guide on ge.ch (checked on 4 September 2026). In both channels the 2025 return of individuals is due on 31 March 2026, or 30 June 2026 if you requested an extension. A paper form remains possible, but it is neither pre-filled nor checked as you type.
What neither GeTax nor the online return does is find the documents: the pillar 3a certificate, the health insurer's annual statement, the dentist's bills, donation receipts, daycare or after-school invoices, the mortgage interest statement. That is the work Floxy takes on all year, in English, so that the French-language entry in Geneva comes down to copying figures that are already sorted.
The initial deadline is 31 March of the current year. Geneva offers no free extension: each request is billed by the length granted, CHF 20 up to 3 months, CHF 40 up to 5 months, CHF 60 beyond (regulation on the AFC's fees). For individuals the filing date can be pushed back to 31 August 2026 at the latest; companies, associations and foundations, the legal entities, have a separate limit of 30 September 2026.
The extension request is made online between 1 January and 31 October, from your e-démarches tax space, through the anonymous form or with the voice guide. From 1 November to 31 December only a reasoned letter to the tax register service is accepted. The AFC confirms or refuses each request by post; it refuses when an extension has already been granted to that date or later.
Without a return or an extension on 31 March, a first reminder is billed CHF 20 since 1 January 2026, then a second reminder with tracked delivery CHF 40. Staying silent leads to an assessment by default and a fine. Requesting the extension before the end of March, then preparing the file over the summer, avoids all of it.
Many employees in Geneva are taxed at source: B or L permit holders living in the canton, cross-border workers living in France. For them the return goes through the subsequent ordinary assessment (taxation ordinaire ultérieure, TOU). According to ge.ch, the TOU is mandatory if you are employed in Geneva with gross annual income of at least CHF 120'000 (for a married couple one spouse reaching the threshold is enough). A resident announces a mandatory TOU, or requests a voluntary one, only once: it then applies to the following years.
Below the threshold a resident can request the TOU to claim actual deductions (pillar 3a, childcare, training, donations). The Federal Tax Administration states that the request is filed by 31 March of the following year, a forfeiture deadline that cannot be extended. A cross-border worker obtains the TOU on request as a quasi-resident: at least 90% of worldwide gross income taxable in Switzerland, with a request renewed every year. The general rules for permit holders across Switzerland are on the B permit guide.
A TOU is prepared like an ordinary return, receipts included. That is where Floxy counts for an English-speaking B permit holder or cross-border worker in Geneva: the year's receipts are already sorted by deduction when the time comes to fill in GeTax for the TOU.
The words you meet in GeTax, in e-démarches and on the AFC's letters, with the meaning Floxy uses in its English categories:
For an employee or a couple without property or self-employment, the Geneva return fits into GeTax or the online return once the documents are gathered, even with school French, as long as the glossary above and a dictionary are within reach. A tax advisor or fiduciary in Geneva keeps its value for a complex situation: self-employment, real estate, an inheritance, partial taxation abroad, the Geneva tax shield, a first TOU with several years of receipts.
Whichever route you take, the receipts are the same, and in Geneva they arrive in French. Floxy reads them as they come: the attestation from your caisse, the crèche invoices, the pilier 3a certificate. Each lands under a Geneva deduction category with the 2025 ceiling attached, so the AFC's French labels stop being a guessing game. Before 31 March you export the folder as PDFs for GeTax or for the advisor you pay by the hour. Floxy files nothing and does not represent you before the AFC. The rest of the household paperwork follows the same logic on the document management page.
Procedure read on ge.ch for the 2025 return. Every request is paid and valid for one precise date: ask once for the length you really need.
Check your date
The initial deadline is 31 March 2026. If you already obtained an extension, the granted date is on the AFC's confirmation letter.
Choose the length
Up to 3 months: CHF 20. Up to 5 months: CHF 40. More than 5 months: CHF 60. For individuals the filing date goes no later than 31 August 2026 (30 September 2026 for legal entities).
File the request online (1 January to 31 October)
From your e-démarches tax space, through the anonymous form or with the AFC's voice guide.
After 31 October: reasoned letter
From 1 November to 31 December only a reasoned letter to the tax register service (Service du registre fiscal, rue du Stand, Geneva) is accepted.
Wait for the written confirmation
The AFC answers every request by post. It refuses when an extension has already been granted to that date or to a later one.
Estimate and prepare in the meantime
Run the AFC's official calculator for an idea of the amount, and scan your 2025 receipts into Floxy as they come: the exported folder is copied into GeTax or the online return in one sitting.
Health insurer's statement, pilier 3a attestation, crèche invoices, receipt of a donation to a Geneva association: each scanned document joins your Geneva tax folder on arrival, named in English, long before 31 March.
Premiums CHF 17'122, commuting CHF 534, childcare CHF 26'320, training CHF 12'756: Floxy's estimate uses the canton of Geneva's 2025 ceilings and the federal ceiling when it is lower.
One folder per deduction, with the totals and the original PDFs: you copy the figures into GeTax 2025 and attach the receipts to the e-démarches online return at the end of the entry, the French labels matched by the glossary.
B permit, quasi-resident cross-border worker or gross income above CHF 120'000: the subsequent ordinary assessment in Geneva needs the same receipts as an ordinary return, and Floxy keeps them ready for the AFC.
In Geneva the return and the assessment are centralised at the cantonal tax administration (AFC): no commune receives or processes your 2025 return. Your commune of residence on 31 December 2025 matters for the communal surcharge (centimes additionnels) added to cantonal tax; its website serves for everything else, from the residence certificate to registering your arrival. Five Geneva communes, in French:
Floxy prepares the file; filing is the business of the Geneva cantonal tax administration, through GeTax 2025 or the online return. The ge.ch pages every Geneva fact above was read on:
On 31 March 2026 at the Geneva cantonal tax administration (AFC), or 30 June 2026 if you requested an extension. With a paid request the filing date of individuals can be pushed back to 31 August 2026 at the latest; legal entities (companies, associations, foundations) have until 30 September 2026. Past 31 March without an extension, a billed reminder follows within days.
No. GeTax 2025 and the online return in e-démarches are published by the Geneva tax administration in French only, as is the AFC's tax guide (checked on ge.ch on 4 September 2026). Prepare your figures in English with Floxy, then enter them in the French fields using the glossary on this page. The French version of this guide, Impôts Genève, walks through the same steps in the canton's language.
Geneva bills each extension by its length: CHF 20 up to 3 months, CHF 40 up to 5 months, CHF 60 beyond, amounts set by the regulation on the AFC's fees. The request is made online from 1 January to 31 October (tax space, anonymous form, voice guide), then by reasoned letter until 31 December. The first reminder costs CHF 20 since 2026, the second CHF 40.
CHF 17'122 for one adult, 2025 tax year, single taxpayer. The ceiling follows art. 32 let. a LIPP: twice the cantonal average premium set by the Federal Office of Public Health, recalculated every year and different for 19 to 25 year olds and for children. It applies to cantonal and communal tax; federal direct tax uses its own flat insurance deduction.
A cross-border worker taxed at source in Geneva whose worldwide gross income is at least 90% taxable in Switzerland. That status opens the subsequent ordinary assessment (TOU) on request, so actual deductions such as pillar 3a, childcare or training can be claimed instead of the flat rates built into the withholding scale. Unlike a Geneva resident, a quasi-resident renews the request every year, with the receipts to match.
If you are employed in Geneva and taxed at source with gross annual income of at least CHF 120'000, the subsequent ordinary assessment (TOU) is mandatory and is announced once to the AFC. Below that, a Geneva resident may request the TOU by 31 March of the following year to claim actual deductions; the Federal Tax Administration describes that date as a forfeiture deadline. Married to a Swiss citizen or C permit holder, you are assessed ordinarily.
Not for a standard Geneva situation: an employee with a salary certificate, a 3a attestation, a premium statement and a few bills can complete GeTax or the online return alone, French labels included, once the documents are sorted. An advisor or fiduciary in Geneva pays off for self-employment, property, the tax shield, a first quasi-resident TOU or income taxed in France as well. Arriving with sorted receipts shortens the billed time either way.
No. The AFC recognises two channels, GeTax 2025 and the online return in e-démarches, and both need your own e-démarches account. Floxy has none. What it does is hold the year's paperwork: the premium statement at CHF 17'122, the crèche invoices, the 3a attestation, each filed under its Geneva line and exported as a PDF. You type the figures into the French form; the AFC issues the bordereau.
