What is My Docs?

My Docs (formerly TurboTax Vault) shows you any tax return you’ve filed in TurboTax Online, past or present, and lets you securely upload and keep all your tax-related documents in one place so you can easily access them when it comes time to do your taxes – or any time you want.

You can store up to 100 MB of scanned receipts, payment confirmations, documentation – whatever you would otherwise keep in a shoebox or filing cabinet. You can even upload your TurboTax PDF and data file backups, as long as each individual upload doesn't exceed 5 MB.
