Sheila, the 2042 is the main income tax form that everyone fills in. usually, if you haven't completed one before you have to request one, normally from your relevant Hotel des Impots but I believe you might be able to download one as France moves into the 21st century. You fill this in with all relevant details plus your salary, any other income (generally) goes onto the 2042 C (commplementaire). This is deja vu - I have mentioned this somewhere else already this year - check out the Tax declaration thread in general info? Surely Henry has some income or perhaps one of you has a pension, you must have some income to declare or you are illegally resident in France???? If you are married - are you? - then you have to fill in the 2042 with all your income, it is not possible to declare separately.
