Can I access my tax documents from multiple devices with cloud software?
Yes. Cloud software lets you access tax documents from a phone, tablet, or laptop as long as the files are stored in the same account and sharing permissions are set correctly. The device matters less than the account, folder structure, and security settings.
This list covers cloud storage and file-sync tools, not tax filing software. It is for people who want tax returns, W-2s, 1099s, and receipts available across multiple devices without emailing files back and forth.
Quick Answer
The best overall cloud software tool for accessing tax documents from multiple devices is Google Drive. If you already use Microsoft 365, Microsoft OneDrive is often the better fit. If you want the simplest cross-device sync, Dropbox is a strong option, and Box is better when permissions and auditability matter.

- Share folders with named users instead of public links.
- Keep one folder per tax year so documents are easy to review later.
- Remove access when the filing work is done.
