Ask questions, upload documents, have opinions and objections drafted – just like a general AI chat, but specialised in tax law. Nyteca® Chat works solely on a verified legal knowledge space and gives every statement its citation and as-of date.

The tax office disallowed CHF 4,800 of continuing-education costs. Can we challenge that?
Reading the notice and checking statute, practice and case law …
Yes. Job-related continuing-education costs are deductible, and the disallowance can be challenged with an objection.
Citations
Ask a question or attach a file …
Illustration — not legal advice
Nyteca® Chat supports you with the work that would otherwise send you to a handbook, a template folder or a colleague.
From the quick question in between to the delimitation where the paragraph and the letter matter – inter-cantonal and cross-border. With a citation rather than a hunch.
Citations
Drop an assessment notice, a contract or annual accounts into the chat: Nyteca® Chat reads along, checks the figures and refers to the document in its answer.
Describe the facts, ask the question, get a structured opinion: facts, legal appraisal, conclusion, citations. A draft to work from.
From the assessment straight to the objection: request, grounds and enclosures, with a note on when the deadline runs out. You review, sign and file.
Weigh structures against each other, check elections and deadlines, work through the consequences – broken down so you can follow it.
No setup, no master data: open the chat, ask the question. Every chat stands on its own – ideal alongside your daily work.
Go to chatNot every question needs an opinion. You choose the level for each chat – it decides how deeply Nyteca® Chat checks, how many sources it draws on and how detailed the answer is.
Level 1
Quick and direct
Clear, short answers for day-to-day work – with the relevant citation and no detours.
Best for
Level 2
Sound and thorough
Examines statute, administrative practice and case law in full, weighs the arguments, works out the counter-arguments and sets out the options – up to the fully reasoned opinion.
Best for
You describe the question, attach documents if needed and choose the level. Tax period, canton and jurisdiction belong to it – without that frame, any tax answer is arbitrary.
The search runs only in the verified legal knowledge space — in the version in force at the as-of date, not today’s.
Every statement carries its citation. What cannot be evidenced is not asserted but flagged as open.
The answer is a draft for a professional. You check it, add to it and stand behind it — the chat saves you the looking up, not the decision.
Because broad knowledge and deep knowledge are two different things. The comparison is with the category of general assistants, not with any particular provider.

Not textbook cases, but what actually comes in.
By when can an objection to an assessment notice be filed, and what suspends the deadline?
How is a company car with private use valued in 2026?
Which receipts are needed to deduct the continuing-education costs of a self-employed person?
Review the attached assessment: why were the property maintenance costs cut?
When does dealing in real estate count as a trade rather than private asset management?
Draft a short opinion: can the restructuring be carried out tax-neutrally?
Nyteca® Chat is already live in Switzerland, and the Nyteca® App follows from mid-November 2026. Both draw on the same legal knowledge space and the same AI functions – the difference lies in how you work with them.
In tax law, a tool that does not name its limits is dangerous. So, explicitly:
Nyteca® Chat is live in Switzerland: open the chat, ask your question, get an answer with citations.
