How it works

  1. You answer the questionnaire at your own pace. Deadline and eligibility checks are free.
  2. You see the final price before ordering, line by line.
  3. You upload your documents to your secure area; a TL Fiduciaire tax specialist checks them.
  4. You approve the procedure; TL Fiduciaire files it through the official channel and sends you the proof.
The personalised conclusion of the analysis is paid. It is about orientation: the financial interest of a procedure is not quantified (no validated simulation) and can be reviewed with a tax specialist. See a sample report (entirely fictitious)
