Allô Impôts 2026: Phone Number, Hours, Topics and Limits

Updated 12 May 2026. Allô Impôts is the telephone helpline operated by France's tax authority (DGFIP) for individual taxpayers. Free and non-premium, it is intended for people with questions about their income tax return, tax notice, withholding tax (PAS) or real estate wealth tax (IFI). In the middle of the 2026 filing season, you are looking for the right number, the exact opening hours, the topics an agent can actually handle and the cases where this first-level information no longer suffices. This article walks through the helpline, the free alternative channels and the situations where Cabinet Hayot Expertise, an accounting and audit firm in Paris, takes over.

Allô Impôts is part of the general contact system of the French tax administration described on impots.gouv.fr. In practice, you dial a single number to reach a public finance agent assigned to answer individuals' questions. The call is free from a landline in mainland France, excluding any mobile operator charge, and is not premium-rated. The number historically published by the DGFIP is 0809 401 401; we recommend checking impots.gouv.fr on the day of your call, as the administration may adjust its contact channels.

Allô Impôts is not a replacement for your personal area on impots.gouv.fr, which remains the official channel to file, pay, check your situation and send a secure message. It complements first-line handling for taxpayers who want an immediate oral answer on a 2042 box, a withholding tax calculation or a campaign deadline.

As of the information available on 12 May 2026, the number displayed by the DGFIP for the Allô Impôts service is 0809 401 401. Published opening hours are Monday to Friday, 8:30 a.m. to 7:00 p.m., excluding public holidays. During the filing campaign — typically from 10 April 2026 to the latest département deadline (mid-June 2026 for zone 3) — call volume rises sharply, with waiting times that can exceed 15 to 20 minutes at peak hours. You will generally find better reachability mid-morning or early afternoon outside the final weeks of the campaign.

If you are calling from abroad, 0809 401 401 is not accessible: you must use the dedicated international line published on impots.gouv.fr (number subject to change; verify at each call). For deaf and hard-of-hearing users, the DGFIP offers chat and French Sign Language video access from the "Contact" page of impots.gouv.fr.

Allô Impôts covers all individual income tax and IFI matters, with a guidance and filing-help focus. In practice, the agent can support you on:

• the 2025 income return (wages and salaries, retirement pensions, rental income, investment income, securities capital gains);
• deductible expenses and alimony paid;
• recurring tax credits and reductions — home services, donations, childcare costs, MaPrimeRénov', the home EV charging credit detailed in our home EV charging tax credit article;
• withholding tax (PAS): personalised rate, individualised rate between spouses, non-personalised rate, BIC/BNC/property income advance payment;
• IFI if your net taxable real estate assets exceed €1.3M, with questions on valuation, allowances and capping;
• changes of situation: marriage, civil partnership (PACS), divorce, birth, death of spouse, move;
• reading a tax notice or a formal notice received.

For investment income and dividend taxation, also read our dividend taxation deep dive, which details the flat tax (PFU) and the progressive bracket option. For separated or cohabiting households, our community-of-life declaration article specifies the reporting obligations.

Allô Impôts is an information service, not a personalised tax-advisory service. The agent cannot validate your return before filing, nor deliver a position binding on the administration. An oral answer does not have the legal weight of a rescrit fiscal (formal tax ruling), and does not pre-empt the outcome of a potential audit. Nor can you use Allô Impôts to file a claim, change your situation or request a payment deferral: these actions go through your personal area or through your Public Finance Centre (CFP).

The scope also stops at business situations. If you are a director of an SAS, majority manager of an SARL, sole-proprietor BIC or BNC, the right contact for your company questions is the Service des Impôts des Entreprises (SIE) of your registered office, not Allô Impôts. The boundary matters: an SARL dividend paid to a majority manager is personal income (see our dividend taxation analysis), but its source — the distribution decision — is a corporate act that may require dialogue with the SIE.

Finally, as soon as your file mixes several income categories (wages + director + property + furnished rental + securities capital gain), a phone call cannot cover all the interactions between regimes. In those cases, the input of an accounting and audit firm in Paris becomes decisive.

Before calling, several free channels often deliver a faster and traceable answer:

• Secure messaging from your personal area on impots.gouv.fr: you send a message to your CFP, typically processed within 5 to 15 working days, with the exchange archived and the option to attach a supporting document. The preferred channel when you want a written trail.
• In-person appointment at the local CFP: booked from the personal area or directly at the counter. Particularly useful for sensitive files (succession, complex IFI, formal notice).
• impots.gouv.fr chatbot: available 24/7, it handles simple questions (box 2042, withholding tax rate, campaign dates) and routes to the right form.
• BOFiP official documentation: for technical questions (furnished rental, dismemberment, IFI, real estate capital gains), the administrative comments published on BOFiP are the binding reference.
• Service-Public.fr: summary fact sheets on the income tax return, IFI and withholding tax.

For a structured patrimonial file, also read our drawbacks of dismembered ownership article, which describes the frequent points to clarify with the administration.

When the question exceeds first-level information, paid support becomes justified. Indicative ranges observed in Paris in 2026:

• Chartered accountant: €150 to €400 excluding VAT per hour for ad-hoc advice, or a fixed-fee engagement starting at €600 to €1,500 excluding VAT for a full review of an income tax return mixing wages, director compensation, property and furnished rental.
• Tax lawyer: €250 to €600 excluding VAT per hour, essential for a contentious tax audit, a high-stakes voluntary disclosure or a litigation with the administration.
• Notary: regulated fees for deeds (donation, succession), free fees for patrimonial advice. Engaged for transfer, IFI on complex real estate, dismemberment.
• Wealth-management adviser (CGP): variable billing, sometimes free where remuneration comes from product retrocession — watch for independence.

For real estate topics (furnished rental at real costs, corporate-taxed SCI, capital gains, property losses), our real estate tax consultation page maps the most frequent trade-offs.

To set expectations, here are three situations in which Allô Impôts is more than sufficient in 2026.

Case 1 — Employee, single or married without children, income limited to wages and salaries. The return is largely pre-filled. You call Allô Impôts to confirm a 2042 RICI box (credits and reductions) or to understand your withholding rate. The agent answers within 5 to 10 minutes.

Case 2 — Retiree receiving pension(s) and a regulated savings account. Income is pre-filled. You verify the 10% pension allowance, you ask whether to declare an interest-bearing current account, you confirm eligibility for a home-services tax credit.

Case 3 — Individual who carried out energy-renovation works eligible for MaPrimeRénov'. You verify reporting in the return, the articulation with any residual tax credit, and the retention of invoices.

In these three cases, Allô Impôts or secure messaging are appropriate and cost-effective channels.

Conversely, some files fall outside the operational scope of Allô Impôts and require an accounting and audit firm in Paris:

1. Multiple income streams: wages + SAS director with dividends + property income + securities capital gain. The PFU vs progressive bracket trade-off, the quotient familial and allowances require a quantified simulation.
2. Furnished rental (LMNP) at real costs: depreciation, form 2031, articulation with property income, capital gains under the non-professional furnished rental regime — documented in Article 35 bis CGI and Articles 39 C onward.
3. Sale of business goodwill or shares: enhanced allowance for retiring directors (Article 150-0 D ter CGI), deferred taxation 150-0 B, suspended taxation 150-0 B ter, contribution-sale schemes.
4. Complex IFI: dismemberment, family SCI, foreign real estate, IR + IFI capping at 75% of income.
5. Donation, succession, business transfer: Dutreil pact (Article 787 B CGI), dismemberment at donation, donation before sale.
6. Tax audit or voluntary disclosure: preparation of a binding file, support through the contradictory rectification procedure (Article L57 LPF), request for discretionary relief.

For these files, the preliminary tax audit run at Cabinet Hayot Expertise typically takes 2 to 6 hours of work, with a written memo delivered. Where relevant, our team coordinates with a notary and a tax lawyer.

As of 12 May 2026, the main dates published by the DGFIP for the 2026 income tax campaign (2025 income) are:

• Online filing service opens: around 10 April 2026.
• Zone 1 deadline (départements 01 to 19 + non-residents): late May 2026.
• Zone 2 deadline (départements 20 to 54): early June 2026.
• Zone 3 deadline (départements 55 to 976): mid-June 2026.
• Paper filing: deadline generally late May for those without internet access — to confirm on impots.gouv.fr.
• Tax notice issued: summer 2026, July to August depending on profile.
• Withholding tax reconciliation: September to October 2026.
• IR balance or refund: September to December 2026.

For IFI, filing happens on form 2042-IFI attached to the income tax return, with the same deadlines. The trigger threshold remains €1.3M of net taxable real estate assets as of 1 January 2026.

Allô Impôts is a valuable first-line service, but its logic is orientation. Our conviction, based on individual and director files in Paris: as long as your tax position fits the pre-filled return plus one or two recurring tax credits, the phone and impots.gouv.fr secure messaging are more than enough. As soon as your wealth starts mixing dividends, rental property, dismemberment or disposal, the cost of a preliminary tax audit pays off through tax savings, but above all through the legal certainty gained in case of an audit.
