Are there any client intake forms that let tax preparers capture e-signatures and upload documents on mobile?

Yes — there are several client intake form tools built for tax preparers that support mobile-friendly e-signatures and document uploads. Common options include:

• TaxDome – client intake forms, secure document upload, e-signatures, mobile app
• Canopy – client portals, forms, e-signature, document collection on mobile
• Liscio – secure client communication, forms, uploads, e-signatures, mobile-friendly
• SmartVault – document collection + secure portal; often paired with other intake tools
• Jotform – can be configured for tax intake, e-signatures, file uploads, mobile responsive
• Typeform + e-sign tool integration – more customizable, but usually needs extra setup

If you want, I can narrow this down based on whether you need:

1. a full tax practice platform,
2. a simple standalone intake form, or
3. the cheapest option with e-signatures and uploads.
