The complete journey of a tax file.
- 01
Collection
Step 1You gather your client's documents — via the client portal, email or manual import. You prepare the declaration in Dr.Tax and import the data into ark.flow. The system files everything automatically.
- 02
Submitted
Step 2The declaration is sent to the tax authority (via Dr.Tax or another channel). The file moves to pending: you are now waiting for the tax decision. ark.flow tracks deadlines for you.
- 03
To review
Step 3The tax decision has arrived. The system automatically compares what was declared with what was retained, and displays every difference in CHF. You decide whether to accept or contest — if so, the file goes back to "submitted" for another round.
- 04
Validated
Step 4The tax decision is accepted — either directly, or after a successful claim. The file is complete for this tax year.
- 05
Archived
Step 5When you're ready, archive the tax year. The file disappears from your daily view but remains accessible anytime in the archives, with its complete history.
Client portal
Your clients submit documents — without creating an account.
One secure link is enough. Your client sees which documents are needed, which are already provided, and the progress of their file. They send everything from their phone. You are notified immediately. No more phone follow-ups.
- A simple secure link — no password, no account to create
- Visual progress: "4 of 6 documents provided"
- Every file is automatically verified on upload
- Immediate notification to the assigned collaborator
Tax file
Every file, every document, every decision — in one place.
The tax file view brings together everything that matters: received documents, AI categorization, declaration/taxation comparison, and progress toward validation. The collaborator sees at a glance where each mandate stands.
- Documents automatically categorized by AI
- DI/DT comparison with differences in Swiss francs
- Visual workflow: Received → In progress → To review → Validated → Archived
Statistics

FAQ
Frequently asked questions about ark.flow Fiduciaire.
-
How much time will ark.flow save me?
Gains depend on your current workflow. In practice, the three main levers are: Dr.Tax import that replaces manual entry for hundreds of files, automatic document filing by client, year and type, and declaration-vs-assessment comparison that catches every numeric difference without line-by-line review. Contact us for a demonstration on your own real files. -
How does the Dr.Tax import work?
ark.flow natively imports Dr.Tax files (.bpt). Each client is created with their complete tax situation: identity, employment, spouse, cantons, tax sections. Field mapping is automatic. Bulk import replaces hours of manual re-entry, even for hundreds of files. -
Do my clients need to create an account for the portal?
No. Your clients receive a secure link by email. They click, see the list of requested documents, and send them directly from their browser or phone. No sign-up, no password to remember. -
How does the declaration vs. taxation comparison work?
When the tax authority's decision arrives, ark.flow reads the document automatically and compares it with the original declaration. Every difference is displayed in CHF with its estimated impact. You choose which points to contest, and the system helps you draft the claim letter. -
Does ark.flow replace Dr.Tax?
No — ark.flow complements Dr.Tax, it does not replace it. Dr.Tax remains your declaration preparation tool. ark.flow handles everything after: document collection, DI/DT comparison, claims, client portal, statistics. Both work together. -
Can I activate modules progressively?
Yes. The Base pack is mandatory and already includes client management, bulk import, AI categorization, email intake and analytics. Then add on-demand the Tax Module (DI/DT comparison + claims), the Client Portal, the Timesheet or the Mail Module — each add-on activates separately, without service interruption. You only pay for what you use. -
Are my clients' data isolated from other firms?
Completely. Every firm gets its own secure environment, its own database and its own encryption keys. No data can mix with another firm's — it is a technical guarantee, not just a policy. Details available on our security page. -
What is the default claim deadline?
ark.flow configures a default 30-day deadline, compliant with most Swiss cantons. This deadline is configurable canton by canton in settings. The system displays visual alerts: normal (> 14 days), amber warning (7-14 days), red urgency (< 7 days).
