If you need to file a capital gains tax return in France, understanding the process before you begin can save you time, money, and unnecessary stress. Whether you've sold property, securities, or other assets, France's capital gains tax system has specific rules, rates, and deadlines that every taxpayer must follow.

This France tax filing guide covers everything you need to know for the 2025/2026 tax year — from determining whether you owe capital gains tax, to completing the correct forms, to submitting your declaration on time. Whether you're a French resident or a non-resident with taxable gains in France, this step-by-step walkthrough will help you navigate the process with confidence.

Understanding Capital Gains Tax in France: The Basics

Before diving into the filing process, it's essential to understand what qualifies as a taxable capital gain in France and how the system works.

Capital gains tax (impôt sur les plus-values) in France applies when you sell an asset for more than its acquisition cost. The French tax system distinguishes between two primary categories of capital gains:

  • Real estate capital gains (plus-values immobilières) — gains from selling property, land, or real estate rights
  • Securities and movable property capital gains (plus-values mobilières) — gains from selling stocks, bonds, mutual fund shares, cryptocurrency, and other financial instruments

Each category has its own tax rates, allowances, and filing procedures, which we'll break down in detail below.

Who Needs to File?

You must file a capital gains tax return in France if you are:

  1. A French tax resident who realized gains from selling property, securities, or other taxable assets during the tax year
  2. A non-resident who sold French real estate or certain French-sourced assets
  3. An EU/EEA resident with specific French-source capital gains subject to withholding or declaration

Even if you believe an exemption applies (such as the primary residence exemption for property), it's important to understand your reporting obligations, as some exemptions still require a declaration.

Step 1: Determine Your Taxable Capital Gain

The first step in how to file taxes in France for capital gains is calculating your actual taxable gain. The basic formula is straightforward:

Taxable Capital Gain = Selling Price − Acquisition Cost − Allowable Deductions

However, the details vary depending on the type of asset.

For Real Estate Capital Gains

When calculating your gain on property sales, you can deduct:

  • Acquisition costs: Notary fees, registration duties, and agency fees paid at purchase (or a flat 7.5% of the purchase price if you cannot provide documentation)
  • Improvement works: Costs of major works that added value to the property (with receipts), or a flat 15% of the purchase price if the property was held for more than five years
  • Holding period allowances: France provides tapering relief (abattements pour durée de détention) that progressively reduce the taxable gain based on how long you owned the property

The holding period allowances for income tax purposes are:

  • 6% per year from the 6th to the 21st year of ownership
  • 4% for the 22nd year
  • Full exemption after 22 years

For social charges purposes, the schedule is slower:

  • 1.65% per year from the 6th to the 21st year
  • 1.60% for the 22nd year
  • 9% per year from the 23rd to the 30th year
  • Full exemption after 30 years

Example: If you purchased a secondary residence in 2012 for EUR 200,000 and sold it in 2025 for EUR 350,000, your gross gain would be EUR 150,000. After applying the flat-rate deductions and 13 years of holding period allowances, your taxable amount would be significantly reduced. Use our France Capital Gains Tax Calculator to estimate your exact liability.

For Securities Capital Gains

For stocks, bonds, and other financial instruments, the calculation involves:

  • Selling price minus acquisition price (including brokerage fees)
  • Potential application of allowances for holding duration if shares were acquired before 2018 and you opt for the progressive income tax scale rather than the flat tax
  • Offsetting of capital losses against capital gains realized in the same year or carried forward from the previous 10 years

Step 2: Know the Applicable Tax Rates for 2025/2026

France applies different rates depending on the type of gain. Here's what you need to know for the 2025/2026 tax year:

Real Estate Capital Gains Tax Rates

Tax Component Rate
Income tax on capital gains 19%
Social charges (prélèvements sociaux) 17.2%
Total standard rate 36.2%
Additional surtax (gains > EUR 50,000) 2% to 6% (sliding scale)

The surtax applies on a sliding scale for net taxable gains exceeding EUR 50,000:

  • EUR 50,001 – EUR 100,000: 2%
  • EUR 100,001 – EUR 150,000: 3%
  • EUR 150,001 – EUR 200,000: 4%
  • EUR 200,001 – EUR 250,000: 5%
  • Over EUR 250,000: 6%

Securities Capital Gains Tax Rates

Since 2018, France applies a flat tax (Prélèvement Forfaitaire Unique or PFU) on securities gains:

Tax Component Rate
Income tax (flat rate) 12.8%
Social charges 17.2%
Total PFU rate 30%

Alternatively, taxpayers can opt to have their securities gains taxed under the progressive income tax scale instead of the flat tax. This may be beneficial if your marginal tax rate is below 12.8%. If you choose this option, it applies to all your investment income for the year — you cannot cherry-pick.

Non-Resident Rates

Non-residents selling French real estate are subject to:

  • 19% income tax (for EU/EEA/Swiss residents) or potentially 33.33% for residents of non-cooperative states
  • 17.2% social charges for non-EU residents, or 7.5% (prélèvement de solidarité) for EU/EEA/Swiss residents affiliated to a social security system in their home country

Step 3: Identify the Correct Tax Forms

Filing your capital gains tax return in France requires using specific forms depending on the type of gain. Getting the right form is critical to a successful filing.

For Real Estate Capital Gains

  • Formulaire 2048-IMM: Used for capital gains on the sale of buildings and similar real estate rights
  • Formulaire 2048-M: Used for the sale of certain movable assets (precious metals, jewelry, art objects)
  • Formulaire 2048-M-bis: For specific situations involving building rights or shares in real estate companies (SCIs)

Important: For real estate sales, the capital gains tax calculation and payment are generally handled by the notary (notaire) at the time of sale. The notary prepares form 2048-IMM, calculates the tax, withholds it from the sale proceeds, and pays it to the tax authorities on your behalf. You do not typically file this form yourself.

However, you must still report the gain on your annual income tax return (see Step 4).

For Securities Capital Gains

  • Formulaire 2042: The main annual income tax declaration, where securities gains are reported
  • Formulaire 2042-C (Complémentaire): The supplementary form for reporting capital gains, investment income, and opting for the progressive scale
  • Formulaire 2074: The detailed declaration of capital gains on securities, used when you need to report complex transactions (carried-forward losses, specific holding period allowances, etc.)
  • Formulaire 2074-ABT: For claiming holding period allowances on shares acquired before 2018

Your bank or brokerage should provide you with an IFU (Imprimé Fiscal Unique) — a summary tax statement of all your investment transactions during the year — which contains the information you need to complete these forms.

Step 4: Complete Your Annual Tax Declaration

Regardless of the type of capital gain, you must report it on your annual income tax return (déclaration de revenus). Here is the step-by-step process:

1. Access the Online Portal

France mandates online filing for most taxpayers through the official tax website: impots.gouv.fr. Log in to your personal space (espace particulier) using your tax number (numéro fiscal) and password.

If you're filing for the first time (common for non-residents), you may need to create an account or file a paper return initially.

2. Complete Form 2042 and Annexes

Once logged in, navigate to the income declaration section:

  • For securities gains under the PFU (flat tax): Report the total net gain in Box 3VG of form 2042-C. If you have net losses, report them in Box 3VH.
  • For opting for the progressive scale: Check Box 2OP on form 2042, then complete the relevant boxes with gross gains, allowances, and any carried-forward losses on form 2042-C and, if necessary, form 2074.
  • For real estate gains: Report the amount already taxed at the notary in Box 3VZ of form 2042-C. This amount is used to calculate the Revenu Fiscal de Référence (reference tax income) but won't be taxed again.
  • For cryptocurrency gains: Since 2019, crypto gains are reported in Box 3AN (gains) or Box 3BN (losses) and are subject to the 30% PFU by default. The detailed calculation is done on form 2086.

3. Attach Supporting Documentation

While online filing doesn't require physical attachments, you should retain:

  • Your IFU from financial institutions
  • Purchase and sale records for all assets
  • Receipts for any deductible costs
  • The notary's statement for property sales
  • Records of any prior-year capital losses being carried forward

Keep these documents for at least three years after filing (the standard audit window), though a six-year retention period is recommended for added safety.

4. Review and Submit

Before submitting, carefully review all figures. The online system will perform basic consistency checks, but it's your responsibility to ensure accuracy. Common errors include:

  • Confusing gross gains with net taxable gains
  • Failing to offset available capital losses
  • Reporting gains in the wrong box
  • Forgetting to check Box 2OP when opting for the progressive scale

Step 5: Meet the Filing Deadlines

Missing the deadline can result in penalties, so mark these dates carefully.

Annual Income Tax Declaration Deadlines (2025)

For income earned in 2024 (declared in spring 2025), the deadlines are typically:

Filing Method Deadline
Paper filing (if permitted) Mid-May 2025 (usually around May 20)
Online filing — Zone 1 (départements 01–19) Late May 2025
Online filing — Zone 2 (départements 20–54) Early June 2025
Online filing — Zone 3 (départements 55–976 + non-residents) Mid-June 2025

Exact dates are confirmed by the French tax authorities (DGFiP) each year, usually in April. Check impots.gouv.fr for the confirmed 2025 schedule.

Real Estate Capital Gains Tax Payment

For property sales, the tax is due at the time of sale and is handled by the notary. There is no separate deadline to worry about for the tax payment itself, though you must still report the gain on your annual return.

Late Filing Penalties

Failing to file on time triggers:

  • A 10% penalty on the tax due if filed within 30 days of a formal reminder
  • A 20% penalty if filed after the 30-day reminder period
  • A 40% penalty in cases of deliberate non-compliance
  • Interest charges of 0.20% per month of delay

Key Exemptions and Reliefs to Know

France provides several important exemptions that could significantly reduce or eliminate your capital gains tax liability:

Primary Residence Exemption

The most valuable exemption: gains from selling your principal residence are fully exempt from both income tax and social charges. No holding period requirement applies, but you must be able to prove the property was your main home at the time of sale.

Holding Period Exemption for Real Estate

As outlined above, secondary residences and investment properties become fully exempt from:

  • Income tax after 22 years of ownership
  • Social charges after 30 years of ownership

First Sale Exemption for Non-Primary Residences

If you haven't owned your primary residence in the past four years, you may be eligible for a one-time exemption on the sale of a secondary property, provided the proceeds are reinvested in purchasing a primary residence within 24 months.

Low-Value Exemption

Property sales with a price below EUR 15,000 are exempt from capital gains tax. For jointly owned property, this threshold applies per co-owner's share.

Securities-Specific Reliefs

  • Retirement relief: Founders of small businesses who sell shares upon retirement may benefit from a EUR 500,000 lifetime allowance
  • Loss offsetting: Capital losses on securities can be offset against gains of the same category for up to 10 years

Double Taxation Agreements and International Considerations

If you are a non-resident or have international assets, France's extensive network of double taxation agreements (DTAs) will affect your filing obligations.

General Treaty Principles

  • Real estate gains: Most DTAs allocate taxing rights to the country where the property is located. If you sell French property, France retains the right to tax the gain regardless of your residence. You can then claim a credit or exemption in your home country under the applicable DTA.
  • Securities gains: These are typically taxed in the country of residence, unless the shares derive more than 50% of their value from immovable property located in France.

For Non-Residents Filing in France

Non-residents must appoint a fiscal representative (représentant fiscal) when selling French real estate if the sale price exceeds EUR 150,000 and they are not residents of an EU/EEA country or a country with a tax administrative assistance treaty with France. The fiscal representative guarantees the accuracy of the tax calculation and payment.

EU/EEA residents have been exempt from the fiscal representative requirement since 2015.

Frequently Asked Questions

Do I need to file if I sold my primary residence?

The gain is exempt from tax, but the notary will still prepare the declaration (form 2048-IMM) noting the exemption. You should verify that the exempt gain is correctly reported in Box 3VZ of your annual return for reference income purposes.

Can I deduct renovation costs from my property gain?

Yes, if you hold receipts for improvement works carried out by licensed professionals. Alternatively, if you've owned the property for more than five years, you can claim a flat 15% deduction on the acquisition price without receipts.

What happens if I made a loss on a property sale?

Unfortunately, real estate capital losses are not deductible against other income or other real estate gains in France. They are simply lost from a tax perspective.

Can I offset stock market losses against gains?

Yes. Capital losses on securities can be carried forward for 10 years and offset against future capital gains on securities. Make sure to report losses in Box 3VH each year to preserve the carry-forward.

How is cryptocurrency taxed in France?

Crypto-to-fiat conversions are taxable events. Occasional investors pay the 30% flat tax (or can opt for the progressive scale). Professional crypto traders are taxed under the BIC (business income) regime. Report crypto gains on form 2086 and carry the totals to your 2042-C.
