Pinpointing the Levers for Your Withholding Tax
Since 2019, it's the new norm: any taxable income, including salaries, pensions, rents, alimony, and sickness benefits, is subject to real-time taxation, with the method possibly varying depending on the income's nature. The withholding rate is calculated by the tax administration using data from your tax return, updated yearly in August, with the new rate taking effect from September.
In case of a decrease or increase in income, you can adjust your withholding rate to prevent over- or under-paying taxes during the year. You can make these adjustments online through the "Manage my withholding tax" section on the impots.gouv.fr website.
Warning: if your evolution in income results in a change in your rate after sending your spring 2025 tax declaration, this change will not be maintained by the tax office in 2026. You will need to make changes again on the tax website (unless you've experienced a change in family situation, in which case the rate will be kept).

Evading Penalties: Calculating Your Tax Rate Correctly
For your source tax rate to decrease if your income drops in 2025, you must first provide the tax administration with a detailed estimate of all the expected income for the entire year. Based on this data, the tax agents recalculate a new tax rate. However, the new rate will only be applied (and subsequently transmitted to your employer and social organizations to which you belong) if the annual tax amount resulting from it is at least 5% (effective since January 1, 2023 – was previously 10%) lower than the initially planned tax rate. Otherwise, your request will be rejected.
Revisiting Income: Adjusting Your Tax Rate
If your income increases in 2025, you can request the tax office to review your rate upward to reduce the extent of the adjustment planned for September 2025 (after your annual tax return is analyzed). The process for requesting a decrease (covered earlier) applies here, but no conditions are required: if the new rate, based on your estimate of your 2025 income, proves to be higher, it will be applied to you.
However, it's essential to note that requesting an increased rate may not be financially advantageous. Instead, consider saving the extra money in a low-risk savings product, such as a bank account, term deposit, or life insurance, then paying the excess taxes due in September 2025.

Non-Salaried Income: Requesting Advance Withholding
Individuals who, for the first time in 2025, have received non-salaried income (ex. benefits from independent workers, rent from a life insurance) are not forced to wait until September 2025 (after the annual tax return) to pay their taxes. Instead, they can request an advance payment – directly deducted from their bank account – setting the amount that works for them. Conversely, if you stop receiving such income, you can suspend the deductions.
Rental Income: The Automatic Withholding System
Rental income is taxed via an automatic installment system: the tax office directly withholds an advance (of your choice, monthly or quarterly) from your bank account as the rent is received. The amount of this advance is calculated based on your declared rents for the previous year. First-time renters, for 2025, will start the withholding only in September 2026, but you can request an advance payment to avoid a large catch-up later on.
Don't worry about the process for realized real estate capital gains; these remain subject to a 36.2% tax, reduced by an allowance of 1 to 2% per year of ownership of the property, collected by the notary during the sale of the property.
💡 Enrichment Data: Rental income below the tax level of €7,600 per year (€633.33 per month) is not subject to withholding tax. If your rental income falls in this category, you do not need to bother with setting up automatic withholding or follow the rest of this section.
Life's Turns: How the Tax Office Tackles Changes
If you've encountered life's twists like marriage, divorce, birth, or death, your withholding rate may no longer match your current situation: it could be either excessively high or low. As before, you can report these changes online to ensure the tax office swiftly rectifies and transmits the updated rate to your employer, Social Security, retirement funds, etc.
In marriage or a PACS, the financial advantage is significant if one partner earns at least 30% more than the other, as their combined income will then be subject to a lower tax bracket. A substantial advantage is also expected for a birth, as the tax office recalculates the rate by adding half a family quotient, or even a whole part if you are raising your child alone or already have at least two other children.
Tax Benefits: Enjoying Your Monthly Credit
In recent years, the payment of certain tax benefits is undergoing modernization. This applies to the 4 million individuals who employ a domestic worker for tasks like household chores or gardening: instead of annualized benefits, the 50% tax credit linked to the expenses incurred is now refunded to them monthly, automatically. This process started partially in 2022 and will be generalized in 2023 (except for childcare services, which will be integrated in 2026).
The Taxation Methods for Various Income Types
The withholding tax system does not affect the actual income tax due; it only changes how the tax authority collects the tax. Depending on the type of income, the payment method varies: employers deduct the tax for wages, but banking institutions collect it for rental income or the income received from independent workers.
Income from investments remains unaffected by the withholding tax system: they continue to be taxed according to the rules established in 2018.
- For effective personal-finance management, it is crucial to recognize that changes in non-salary income, including rental and investment income, may necessitate adjustments in advance withholding to prevent under- or over-paying taxes.
- In the context of personal-finance planning and real estate investments, it's important to note that income from sold properties is subject to income tax at a rate of 36.2%, with certain allowances based on the property's ownership period.
