What happens after you write
One person reads and replies. There is no support desk and no automated response. Allow 24 to 48 working hours, a little longer over holidays. If nothing arrives within three days, check your spam folder before writing again. For a partnership proposal, describe precisely what you are offering: generic messages go unanswered.
What I cannot do for you
I am not a tax adviser and I give no personalised advice. I cannot settle your particular situation, fill in your return, or tell you what the administration will decide. For an answer that binds, contact the FPS Finance, your health insurance fund or your family allowance fund, depending on the subject. If a figure on this site looks wrong to you, however, do say so: I reopen the official source, correct it if needed, and the correction is public.
