Before you open a chat
- Turn off model training. In ChatGPT: Settings, Data controls, turn off "Improve the model for everyone." [1]
- Or use a Temporary chat: OpenAI says these are not used to improve models and may be kept up to 30 days for safety. [1]
- Note that rating a response with thumbs up or down can make that conversation usable for training even after opting out, per OpenAI. [1]
Never paste
- Social Security or ITIN numbers
- Bank account and routing numbers
- Your IRS Identity Protection PIN
- Full scans of W-2s, 1099s or prior returns
- Your address, date of birth or employer ID
Do this instead
- Describe your situation in general terms and round numbers.
- Copy only the question text from your software, not your answers.
- Using a browser or computer-use agent? Follow the extra rules in AI agents for your taxes.
Protect your identity at the IRS
- Get an IRS Identity Protection PIN, which helps prevent someone filing a return with your SSN. [2]
- Watch for AI-enabled scams: the IRS warns of AI-driven impersonation calls and fake IRS messages. [3]
The IRS generally contacts taxpayers by mail first and does not call to demand immediate payment. [3]
