Project Overview
A Switzerland-based tax services firm needed a secure, compliant, and user-friendly web application to manage end-to-end tax applications for private individuals. Their existing process relied heavily on emails, manual document handling, and spreadsheets, which led to delays, errors, and compliance risks.
The goal was to build a centralized digital platform that allows clients, tax agents, and administrators to collaborate securely while maintaining a complete audit trail required under Swiss regulatory standards.
Business Challenges
- Manual and fragmented tax application handling
- Lack of real-time application status visibility for clients
- Secure document collection and version control issues
- No structured audit trail for legal and compliance needs
- Inefficient communication between clients and tax agents
- Difficulty managing multiple roles with different access levels
Solution Delivered
We designed and developed a role-based tax application management platform using the MERN Stack, tailored specifically for Switzerland-based tax companies.
The platform digitizes the entire tax workflow—from client registration to government submission—while ensuring data security, transparency, and regulatory compliance.
Key User Roles
Client (Private Individual)
- Online registration with secure credentials
- Create and submit tax applications
- Upload required documents
- Review and approve service offers
- View and approve final tax documents
- Track real-time application status
Tax Agent
- Review assigned applications
- Change application statuses
- Request additional documents
- Send service offers to clients
- Upload final government tax documents (PDF)
- Submit approved applications to government authorities
Admin (Optional)
- Manage users and tax agents
- Control system settings and templates
- View system-wide logs and audit trails
- Monitor platform activity for compliance
Application Workflow
- Client creates a tax application (Draft or Submitted)
- Tax agent reviews and marks application as In Progress
- Agent sends a service offer to the client
- Client approves or rejects the offer
- Client uploads required documents securely
- Agent uploads final government tax document
- Client reviews and approves final document
- Agent submits application to the government
- Application is marked as Completed and archived
Application Status Management
The system supports a clear, client-visible status flow, including:
- Draft
- Submitted
- In Progress
- Waiting for Documents
- Documents Uploaded
- Offer Sent
- Offer Approved / Rejected
- Final Document Shared
- Approved by Client
- Submitted to Government

This transparency significantly reduced follow-ups and support queries.
