Can you recommend corporate tax software for automating workpaper assembly and multi-jurisdiction business return prep?

If the priority is assembling workpapers from source systems, trial balances, and supporting schedules, I’d especially evaluate:

Also consider whether you need a dedicated document management / workpaper management layer rather than just tax prep software.

• ONESOURCE
• CCH
• Corptax

What to ask vendors in demos

To narrow this down, ask each vendor:

1. How do you ingest trial balance and GL data?
2. Can you automate workpaper tie-out and support schedules?
3. How does the software handle multi-entity, multi-state, and apportionment?
4. What return forms and jurisdictions are supported?
5. How does the review/approval workflow work?
6. Can it integrate with Excel, ERP, and document management systems?
7. What is the implementation timeline and required admin effort?

If you want, I can also give you:

• a side-by-side comparison table
• a shortlist by company size
• or a recommendation based on your ERP and number of entities/jurisdictions.
