AgentI is a team of AI agents working for you. They read every document you send, build one complete household file, estimate your tax in any canton and handle the intercantonal apportionment automatically. When a document is missing, the agents reach out to your customers directly by email (inbound and outbound) and collect the missing files in a one-time drop space — no password, no account to create. They even request your filing extension. Next year, it is all still there. You just confirm what changed.
Access Your Portal → See what AgentI does ↓Send your documents however suits you. From there, each agent owns one part of your tax file — reading, structuring, estimating, apportioning and exporting — and they work together until your declaration is ready.
A reader for every kind of paper. AgentI recognises and fully reads 22 categories of tax documents — salary certificates, pillar 3a, bank & securities statements, insurance, property, childcare, medical, donations and more — capturing every figure, nothing omitted.
Assembles one unique household file — both spouses, children, every income, asset and deduction — de-duplicated and consolidated. Each number is traced back to the exact document it came from, so nothing is double-counted and nothing is lost.
Every document is stored securely and permanently linked to you, kept for the full statutory retention period and retrievable in a click. The link is what makes next year effortless — your file is never built from scratch again.
Compares the file against everything a complete declaration needs, then simply asks your customer — by email or a one-time secure link, with no password to set, no account to create, nothing complex. Your customer just replies with the document, and AgentI reads the reply and slots each missing document back into its right place automatically. No forms, no checklists to decode.
Calculates your income, wealth and tax for any canton and commune using official rates — applying every deduction you are entitled to. See the federal, cantonal and communal breakdown before you file, with no surprises.
Own property or have ties in more than one canton? AgentI performs the automated intercantonal apportionment (Steuerausscheidung) — splitting income and wealth across cantons and communes exactly as each authority requires.
Where you are resident on 31 December decides what you pay. AgentI lets you simulate moving your main residence (Hauptsitz) to another canton or commune and see the tax impact instantly — same income, same family, a very different bill. Decide where to live with the numbers in front of you.
Five things a spreadsheet and a folder of PDFs will never do for you.
Every document stays permanently linked to you. Your second declaration is not a blank page — it opens pre-filled from last year, and you only confirm what actually changed.
Salary certificate, 3a attestation, bank statement, mortgage interest, a photo of a receipt — in any layout and any national language. AgentI reads and understands it automatically.
Running late? AgentI requests your filing-deadline extension (Fristerstreckung) with the canton for you, automatically — so you stay compliant without lifting a finger.
AgentI generates the exact import file for your canton's official tax portal. Your figures load straight into the cantonal e-filing system — no re-typing, no transcription errors.
Your data follows the official Swiss eCH-0278 e-government tax standard end to end — structured, portable, future-proof and accepted by the authorities.
A live estimate for any canton and commune, deductions and intercantonal apportionment all included — so you know exactly where you stand, and where you could stand.
If your tax situation is more than a single salary slip, AgentI was built for you.
Two incomes, children, a mortgage, pillar 3a and a holiday flat in another canton — exactly the situation where deductions and apportionment get complicated, and where AgentI saves the most.
Moving canton, multiple communes, or weighing where to settle next. AgentI keeps every year linked and lets you model the impact of a move before you make it.
Open your portal, send your first documents, and watch your household file build itself — canton-ready and eCH-0278 compliant.
