What Nyteca® Chat does for your fiduciaire
Like a general AI chat, but specialised in tax law: no setup, no master data – open the chat, ask the question.
Answer tax questions
From TVA (AED) and impôts directs (ACD) to the taxation of cross-border workers: Nyteca® Chat answers on Luxembourg law and cites the relevant provision.
Upload documents
Drop a bulletin d’imposition, a contract or annual accounts into the chat: it reads them and refers to them in its answer.
Draft opinions
Describe the facts and get a structured opinion: facts, legal appraisal, conclusion, citations – a draft to work from.
Prepare réclamations
From the bulletin d’imposition to the réclamation: request, grounds and enclosures, with a note on the running deadline. You review, sign and file.
Two levels of depth
The short answer for day-to-day work or the full review of complex and cross-border matters – you choose for each chat.
A citation for every statement
Every statement carries its citation, version and as-of date. What cannot be evidenced is flagged as open.
Typical questions from a fiduciaire
- By when must the annual TVA return be filed with the AED?
- How is the income of a cross-border worker resident in France taxed?
- Review the attached bulletin d’imposition: why were the frais d’obtention not accepted?
- Draft a réclamation against the bulletin d’imposition – with deadline and grounds.
