The number of tax returns you can file at one time using TurboTax depends on whether you are using the online or desktop version:
- If you use TurboTax Online, you can file one federal return with up to five state returns per Intuit Account.
- If you use TurboTax Desktop, you can file five federal returns with up to three state returns each.
- No more than five Intuit accounts and five corresponding federal returns (for example, for a family of five) may be created, purchased, and filed using any one email address.
- Per IRS rules, you can only e-file up to five federal returns using the same email address or phone number with personal tax return preparation products.
