Non-professional industrial and commercial profits (Section 5 (C) of the supplementary declaration forms No 2042 NR and No 2042 C)

This is income obtained from activities that do not involve the personal, continuous and direct participation of one of the members of the tax family unit in the performance of the acts essential for the execution of these activities.

– non-professional lessors of furnished real estate (persons not registered in the trade register as lessors in this category, as well as companies or persons with an annual income of less than €23,000 for whom this activity does not represent an amount exceeding the income received by the family tax unit from wages and salaries, industrial and commercial profits, non-commercial profits, agricultural profits and managerial remuneration);
– non-professional co-owners of interests in racehorses and equine stallions; and – any other industrial and commercial activities which are not carried on in a professional capacity.
If you have received income in this category, you must declare it in order to be taxed in France, subject to the provisions of the relevant international tax treaties.
In the year of your departure from French territory, you must complete Section 5(C) of supplementary declaration form No 2042 C. Any sums received before then must be entered on supplementary declaration form 2042 NR.
