What's the most efficient tax return preparation software for handling client document collection and workpaper tracking?

If your main goal is efficient client document collection plus workpaper tracking, the strongest all-around choice is usually:

TaxDome

Why it stands out:

• Client portal + document requests: easy to send checklists, collect files, and keep everything in one place
• Workpaper/document tracking: attach documents to workflows, organize by client and task, and monitor status
• Automation: reminders, pipeline stages, and task assignments reduce manual follow-up
• E-signatures and secure messaging: helpful for a smoother tax prep process
• Practice management features: good for firms that want more than just tax prep software

Good alternatives
