What Nyteca® Chat does for your fiduciary firm
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 the VAT deadline to the inter-cantonal tax allocation: Nyteca® Chat answers for the Confederation and the cantons and cites the relevant provision.
Upload documents
Drop an assessment notice, salary certificate, 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 objections
From the assessment notice to the objection (Einsprache): request, grounds and enclosures, with a note on the running deadline. You review, sign and file.
Two levels of depth
Associate for the quick answer, Advisor for the balanced assessment and the complex or cross-border case.
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 fiduciary practice
Go to chat- When is the VAT return for the second quarter due?
- How is a person taxed who moves to another canton during the year?
- Review the attached assessment notice: why were the property maintenance costs cut?
- Draft a short opinion: can the restructuring be carried out tax-neutrally?
What you can rely on
Servers in Switzerland

We process personal data under the Swiss Federal Act on Data Protection (FADP); the data in your questions and uploaded documents is covered by a data processing agreement (DPA) under Art. 9 FADP. For mandates with a link to the EEA, we take the GDPR into account.
