Are there any tax preparation software platforms that handle secure document uploads and multi-state personal returns?

Yes. Several tax preparation platforms support secure document uploads and can handle multi-state personal returns, though the exact features vary by product and by whether you’re using a consumer, professional, or online/self-prepare version.

Common options

• TurboTax
  • Supports secure document upload via its online platform.
  • Handles multi-state returns in many cases, especially for people who worked or lived in multiple states.
• H&R Block
  • Offers secure document storage/upload features.
  • Supports multi-state personal returns.
• TaxAct
  • Provides document import/upload capabilities.
  • Supports filing in multiple states, depending on the return type.

Professional tax software

If you mean software used by tax preparers, many professional systems handle both:

• Intuit ProConnect Tax
• Drake Tax
• CCH Axcess Tax
• Lacerte
• UltraTax CS

These generally support:

• secure client portals for document upload
• multi-state individual returns
• e-signature and organizer workflows

What to verify before choosing

Not every platform handles all multi-state scenarios, so check for:

• part-year resident filings
• nonresident income allocations
• reciprocal state agreements
• multiple W-2 states
• state credits for taxes paid to other states
