Tax firms

Tax Firm Management Software

For firms with more than one person on every engagement: assignments, review steps, shared documents, deadline oversight, billing and a client portal in a single tenant workspace.

Key benefits

What Changes for Your Practice

Multi-user by design

Invite staff, assign roles, and give each engagement a preparer and a reviewer.

Client assignments

Every client has named owners, so queries and work reach the right person.

Review built in

Workflow steps can require review and client approval before completion.

Shared document store

Documents are visible to the team by client, category and financial year.

Firm-wide deadlines

Compliance obligations roll up so partners see risk across the client base.

Isolated tenancy

Your firm's data is separated from every other firm at the database level.

Coordination is the constraint

As soon as a second person touches an engagement, the firm needs to answer questions that a solo practitioner never asks: who owns this, has it been reviewed, was the client's answer recorded, can we hand this over without losing context. TaxOS keeps those answers on the engagement itself.

Assignments and roles

Staff are invited by email and hold roles that determine what they can access. Clients, tasks and workflow steps carry named owners, and internal chat with secure file sharing and mentions keeps discussion attached to the work.

  • Role-based access to clients, billing and settings
  • Owners on clients, tasks and workflow steps
  • Internal chat with mentions and file sharing
  • Notifications when work needs attention

Workflows and compliance across the firm

Service-driven workflow templates give each engagement type its ordered steps. Compliance items track deadline, priority, risk, assigned employee, required documents and status, from upcoming through overdue, so the firm can reallocate before a due date becomes a problem. TaxOS is practice-management software. It tracks, reminds and organises the work around compliance — it does not file returns with any government portal and never stores portal credentials.

Billing across service lines

Invoices draw on the services engaged for each client, with GST computed in paise-accurate arithmetic, payments recorded against invoices, and receipts available to the client in their portal.

FAQ

Questions Firms Ask Before Switching

How many users can we add?

Invite the team you need; roles control what each member can access inside your workspace.

Can two staff work on the same client?

Yes. Clients, tasks and workflow steps have their own owners, so preparation and review can run in parallel.

Is our data separated from other firms?

Yes. Every record is scoped to your organisation and enforced by row-level security in the database, not only in the interface.

Does TaxOS file with government portals?

TaxOS is practice-management software. It tracks, reminds and organises the work around compliance — it does not file returns with any government portal and never stores portal credentials.
