TaxAssembly Professional
Client files, document preview, and internal memos in one workspace — built by a tax professional for day-to-day prep.
Client portal
Track status, keep notes, and discuss the return with your team — without switching tools.
Workflow, checklist, memos, and documents in one view.
Client details and updates stay organized with the file.
Review the return with your team on the same page.

Document preview
Upload files, open current or prior-year docs, and copy values without leaving the client workspace.
JPG, PNG, HEIC, PDF — keep source docs with the client.
Current and prior-year files, ready when you need them.
Copy and paste directly from the inline preview.
Also available
TaxAssembly Education uses the same client-file approach for students — realistic cases, documents, and firm-style workflow.
