IonBin provides general information and software comparisons, not tax, legal, accounting or financial advice. Tax and legal rules vary by situation and jurisdiction; consult a qualified professional (CPA, enrolled agent or attorney) before acting.
AI tools can make mistakes. Verify every figure against the original documents and official IRS or state guidance before filing or signing.
Redact Social Security numbers, account numbers and EINs before uploading documents to any AI assistant, and check its data-retention settings. Upload originals only to the filing or signing software.
“Free” offers come with conditions: check who qualifies and what state filing costs before you start. IRS Direct File is discontinued for the 2026 season with no relaunch date; see IRS Free File for eligible filers.

How TurboTax connects to each AI platform: native connector or MCP, API through code the agent writes, browser control, or file upload.

TurboTax's docs also name: ChatGPT.
Confirmed means both the tool's and the platform's official docs describe that route (links in the cell); IonBin has not tested every pairing. Not documented means it may work, but no official docs describe that route end to end. Checked Oct 17, 2026.
