*Online filing is the default in France — but paper filing remains a legal option for specific situations. The two methods have different deadlines, different processes, and one significant trap that catches people out every year.*

**The golden rule:** if you have an internet connection and online access, you are expected to file online. Paper filing is a legal exemption — not a free choice — and it comes with an earlier deadline that has already passed for 2026.

For an overview of the French filing process more broadly, see our guide to [filing French taxes as a UK expat: the PPMF framework](https://www.taxpert.fr/blog/filing-french-taxes-uk-expat-guide).

## The Legal Position — Paper Is an Exemption, Not a Choice

Online filing became the default under **Article 1649 quater B quinquies of the Code général des impôts**. You are legally permitted to file on paper only if you declare on your honour that either:

- Your main residence is not equipped with an internet connection, or - You are physically or technologically unable to use the online service

Paper filing is framed as an exemption for those who genuinely cannot file online — not as an alternative method for those who would simply prefer it.

## Who Can Legitimately File on Paper

There are three groups who can file on paper:

**1. True first-time filers** If you are a new resident in France and do not yet have the credentials to access your *Espace Particulier* on impots.gouv.fr, you cannot file online for your first return. Paper is the only route until your account is set up. See the first-time filer section below.

**2. The digitally isolated** People living in areas with no reliable internet access (*zones blanches*), or individuals who lack the equipment or capability to navigate the online system.

**3. Specific administrative edge cases** Occasionally, complex changes in civil status — such as a simultaneous divorce and inheritance overlap early in the tax year — cannot be processed correctly by the standard online filing wizard. In these cases, local tax offices may direct people to a paper return.

> **Note on foreign income and supplementary forms:** Having foreign income, a micro-entrepreneur business, or capital gains does not force you onto paper. These income types simply require adding the digital versions of the relevant supplementary forms — 2047, 2042-C, 2042-C-PRO — within the online system.

## The 2026 Deadlines — Online Filers Get More Time

This is the most important practical difference. Paper filers face a significantly earlier deadline than online filers.

Your zone is determined by your department number as of 1 January of the tax year. Online filers in Zone 3 have over two weeks more than paper filers. This is one of the most compelling reasons to file online if you have the option.

To check your department number, see the [French tax glossary](https://www.taxpert.fr/blog/french-tax-glossary-uk-expats) entry for *Zone de déclaration*.

## Where to Get Paper Forms

If you are filing on paper, there are three ways to get the forms:

**1. Automatic postal delivery** If you filed on paper last year and have not switched to a fully digital account, the main Form 2042 is automatically printed and posted to your home address by the DGFiP during April.

**2. Download from impots.gouv.fr** The blank Form 2042 and all supplementary forms are available to download as PDFs from the public side of impots.gouv.fr. Search for "Formulaire 2042", download, print, and post.

**3. Your local tax office or France Services hub** You can collect physical copies of the main form and its annexes from your local *Service des Impôts des Particuliers* (SIP) or a nearby France Services communal hub.

## First-Time Filers — Getting Into the System

If you have just arrived in France and do not yet have a *numéro fiscal* (French tax identification number), you cannot access the online filing system. You need to obtain your number first, then file.

There are two ways to do this:

**Option A — Online (recommended)**

1. Go to impots.gouv.fr and navigate to: *Contact et RDV → Vous êtes un particulier → L'accès à votre espace particulier → Je n'ai pas de numéro fiscal* 2. Complete the identity creation form with your full civil status and address, and attach a scanned copy of your identity document 3. The tax authority will send your credentials (numéro fiscal and online access number) by post or email, allowing you to complete your first declaration online

**Option B — In person at your local tax office**

Visit your local *Service des Impôts des Particuliers* (SIP) and request the creation of a numéro fiscal. Bring a valid identity document and proof of address.

Once you have your numéro fiscal, you file online from that point. For full details on the numéro fiscal and what it is used for, see our [Cerfa 2043 guide](https://www.taxpert.fr/blog/cerfa-2043-french-tax-number-uk-expats).

## The Automatic Declaration Trap

This is the mistake that catches people out most often on paper returns.

France operates an **automatic declaration** (*déclaration automatique*) system for households with simple, pre-filled income. If the DGFiP has marked your dossier as eligible for this track, and the pre-filled data is correct, you do not need to actively sign or return your form — silence is treated as agreement.

**The trap:** many people receive a regular paper return — without the automatic declaration designation — and assume the same rule applies. It does not. If you receive a standard paper form and do not actively sign and return it by the deadline, a **10% late payment penalty** applies.

The automatic declaration only applies if the DGFiP has explicitly flagged your return as eligible. If you have foreign income, foreign bank accounts, or micro-entrepreneur revenues — which applies to almost every UK expat — you will not be on the automatic track. You must actively file.

## Common Mistakes

1. **Missing the paper deadline.** The paper deadline of 19 May 2026 has already passed for the 2026 declaration. If you are reading this during filing season and have not yet filed, switch to online immediately.

2. **Assuming foreign income forces paper.** It does not. Foreign income declared on Form 2047 can be handled entirely within the online system by adding the supplementary form digitally.

3. **Treating the automatic declaration as a pass to do nothing.** Automatic declaration applies only to those explicitly designated by the DGFiP. If you have foreign income or foreign accounts, you are not eligible — you must actively file.

4. **Not getting a numéro fiscal before filing season.** First-time filers who wait until May to obtain their numéro fiscal will almost certainly miss the paper deadline and have insufficient time to set up online access. Apply as soon as you have a French address — either online via impots.gouv.fr or in person at your local SIP.

5. **Not keeping proof of posting.** If filing on paper, always use *lettre recommandée* (recorded post). The postmark date is your proof of compliance — without it you cannot demonstrate you filed on time.

## Frequently Asked Questions

### Do I have to file online in France?

Online filing is the legal default. Paper filing remains permitted as an exemption for those without an internet connection or who are unable to use the online service. If you have reliable internet access, you are expected to file online.

### What is the deadline for filing my French tax return in 2026?

Paper filers: 19 May 2026 (postmark). Online filers: 21 May (Zone 1, departments 01–19), 28 May (Zone 2, departments 20–54), or 4 June (Zone 3, departments 55–976). Your zone is determined by your department number as of 1 January of the tax year.

### Does having foreign income mean I have to file on paper?

No. Foreign income declared on Form 2047, capital gains, and supplementary income types can all be handled online by adding the relevant digital supplementary forms within the online system.

### I just arrived in France and don't have an online account yet — what do I do?

You need to obtain your numéro fiscal first. The recommended route is online — go to impots.gouv.fr, navigate to *Contact et RDV → Vous êtes un particulier → L'accès à votre espace particulier → Je n'ai pas de numéro fiscal*, complete the form and attach your identity document. Alternatively, visit your local SIP in person with ID and proof of address. Once you have your number and credentials, file online.

### What is the automatic declaration and does it apply to me?

The automatic declaration allows households with simple, pre-filled income to stay silent if the pre-filled data is correct — silence is treated as agreement. It only applies if the DGFiP has explicitly designated your return as eligible. If you have foreign income, foreign bank accounts, or micro-entrepreneur revenues, you are not eligible and must actively file.

### I missed the paper deadline — what do I do?

File online immediately. The online deadlines (21 May, 28 May, or 4 June depending on your department) are later than the paper deadline. If online filing is available to you, use it.
