ChatGPT can help you turn an unfamiliar tax term into a question you understand. That doesn't make its answer ready to put on a return. The Taxpayer Advocate Service warns against relying solely on AI-generated tax advice, particularly for complex questions. You're responsible for the information you file. Use the explanation to work out what needs checking, then verify the rule and the figures before acting on it.
Give it a limited job
Start with a small request, such as explaining a paragraph from an official instruction in plain language. Ask it to distinguish the rule from any assumptions it has made. You can also use a draft checklist to organize questions for a preparer. Keep that checklist open to correction: a clear answer can still leave out a condition that matters to you.
Open the sources yourself
Ask for the official source and the tax year behind a claim, then open it yourself. OpenAI's guidance says important numbers and claims need verification, and high-stakes decisions need appropriate expert review. Check that the cited passage supports the answer, rather than accepting a real link attached to an unrelated explanation. If you can't find the claimed rule, leave the point unresolved.
Keep identifying details out
You don't need to paste a Social Security number, bank account number or complete return into a general chat to ask what a term means. Use fictional details for a learning example. Before uploading financial documents anywhere, review the service's current data handling terms and settings. Removing a name alone doesn't establish that the remaining document is anonymous.
Choose help by the work you need
A question about one form, preparation of a whole return and help with an IRS examination are different services. Ask a prospective preparer what the fee covers and what follow-up is included. Someone paid to prepare all or substantially all of a federal return generally needs a preparer tax identification number, or PTIN. Having that number doesn't establish specialist expertise.
Give the transaction its details
A house purchase, business sale or inheritance needs more explanation than the name of the event. Gather the dates, ownership records and relevant documents for the person reviewing it. Don't assume a purchase creates a deduction or an inheritance produces the same tax result for every recipient. Ask which facts affect the treatment before asking for a final number.
Check representation rights
The IRS credentials guide distinguishes preparation from representation. Enrolled agents, CPAs and attorneys have unlimited representation rights before the IRS; some other preparers have limited rights, and others have none. Confirm the person's current credentials and the service they agree to provide. A third-party checkbox on a return doesn't authorize audit representation. A chatbot isn't your appointed representative.
A worked example needs limits
Suppose a learning example adds hypothetical amounts of $750 and $250. The total is $1,000, but correct addition doesn't establish that either amount is deductible. Check the rule, eligibility conditions and records separately from the arithmetic. A successful demonstration using supplied tax text also doesn't prove that another model or a different personal situation will produce a correct return.
Ask how a preparer uses AI
A professional may use AI for research or drafting while still reviewing the work. IRS guidance issued in June 2026 stresses diligence, competence and protection of client information when tax practitioners use these tools. Ask how your information is handled and who checks the result. Using AI doesn't, by itself, tell you the quality of the service or the fee you should expect.
Match the year and jurisdiction
A useful explanation can still concern the wrong filing year or the wrong tax system. Identify the return you're working on, then check the corresponding official forms and instructions. Federal guidance doesn't settle every state question. If the response mixes years, uses an old threshold or assumes a rule applies everywhere, return to the source before copying any result.
Review the return line by line
Compare income entries with the documents you've gathered and check how deductions and credits were calculated. Review filing status, dependent information and any required schedules. The IRS also advises checking signatures and direct-deposit details. Software checks can help find errors, but don't treat acceptance of an electronic return as proof that every tax position is correct.
Keep a record of what was checked
Save the official instructions you used, the relevant documents and the questions you resolved with your preparer. Keep any remaining uncertainty visible instead of turning a chatbot's confident wording into a decision. Before signing, make sure you understand the entries and have a copy for your records. That review still belongs to you when someone else prepares the return.
