TLDR: You must declare the taxable remuneration you pay, in accordance with the rules applicable to your situation. The declaration may concern, in particular, certain allowances and business expenses, the amount withheld at source, or the net taxable amount. The frequency and procedures vary depending on the applicable scheme; the available sources do not specify the exact dates or all the technical fields.
Who must declare remuneration
You are required to file a declaration if you are an individual or legal entity that pays taxable wages, emoluments, salaries or other remuneration. The obligation therefore falls on the remuneration debtor, not on the employee who receives it.
In the specific context of seconded employees covered by the doctrine examined, you must also provide the necessary information to the employees concerned so that they can declare their income. This indication relates to this particular situation and must not be extended to all employees working abroad without further verification.
What information must be declared
For each beneficiary belonging to the management staff or executive staff, you must show separately:
- allowances for employment-related expenses received;
- representation expenses;
- travel expenses;
- mission expenses;
- other business expenses allocated or reimbursed during the previous year.
The source requires this distinction for the beneficiaries concerned, but it does not specify the technical format for transmitting this information.
Monthly declaration of withholding at source
If you are required to make the withholding at source provided for by Article 204 A, you must declare to the tax authorities each month, for each beneficiary, the information relating to the amount withheld from the income paid.
The declaration may be submitted directly or, in certain situations provided for by the text, through the competent body. The sources examined do not make it possible to provide further details on the procedures applicable to each category of employer.
Annual declaration of the net taxable amount
If you fall within the category of debtors mentioned in Article 204 C, B, 2°, a), and you pay wages and salaries under the conditions provided for by that provision, you must declare each year, for each beneficiary, the information relating to the net taxable amount for income tax purposes.
This amount is determined in accordance with Article 204 F. The filing date is set by order of the minister responsible for the budget; it is not indicated in the available sources.
The case of the DSN
If you are required to file a nominative social declaration, your reporting obligations follow the technical standard mentioned in Article R. 133-13, III, of the Social Security Code.
The available sources do not reproduce the specific fields to be completed for each situation involving work abroad. Therefore, on this basis alone, you cannot deduce the technical details of the DSN applicable to your employee.
What the sources do not make it possible to specify
The sources examined do not make it possible to determine:
- the form or online service used for the ordinary declaration;
- the exact calendar dates of the monthly and annual declarations;
- the DSN fields specific to each situation involving work abroad;
- a general income tax exemption rule for all employees working outside France.
You must therefore distinguish between the employer’s reporting obligation, the frequency provided for by the applicable scheme, and any special rules concerning the employee’s taxation.
