Can you use AI to do your taxes? What's safe and what isn't

Can you use AI to do your taxes? For a lot of the work, yes, as long as you keep the decisions. A chatbot is good at the boring middle of tax season: sorting a year of receipts, explaining what a form is asking for, and turning a folder of PDFs into a checklist. It's bad at the parts that cost you money when they go wrong, such as knowing this year's numbers, knowing your situation, and knowing when it doesn't know.

So use it to get organized and to understand things, then run the numbers in a proper calculator and file through tax software or a preparer. Keep your Social Security number and full tax documents out of the chat. One rule holds whichever tool you use. The IRS's Taxpayer Advocate Service says "you are responsible for everything on your tax return, even when someone else prepares it." A chatbot doesn't even count as someone.

Freelancers have the most to gain here, and the most to lose. Nobody withholds tax from client payments, so your return is where everything gets settled: income tax, self-employment tax, every deduction and the estimated payments you made during the year. That's a lot of admin for AI to help with, and a lot of numbers for it to get wrong.

Can ChatGPT do my taxes?

It can help with parts of it. A general chatbot like ChatGPT, Claude or Gemini can explain tax rules in plain English, answer follow-up questions, draft a list of what you need and check your reasoning. It doesn't file anything on its own. Returns are submitted through tax software or a preparer, and even if you reach that software through a chat window, the software asks the questions, does the calculations and sends the return.

The useful distinction is between a general chatbot and tax software with AI built in. The chatbot answers whatever you ask, with the same confidence whether it's right or wrong. Tax software walks you through a fixed set of questions, uses the current year's forms and does the arithmetic itself, and the AI in it is mostly there to explain things along the way. That's a much safer place for AI to be involved in your return.

If you're asking because you'd rather not pay for tax software, check IRS Free File first. Its guided tax software is free for a federal return if your adjusted gross income is $89,000 or less, and Free File Fillable Forms are available at any income if you're comfortable filling in the forms yourself. That gets you correct arithmetic at no cost, which is more than any chatbot promises.

Where you can use AI to do your taxes safely

The safe uses have one thing in common: you can check the output yourself in a minute or two.

• Sorting expenses. Paste in a list of transactions (descriptions and amounts, nothing else) and ask it to group them into likely Schedule C categories: software, advertising, office expenses, travel. You still decide what counts as a business expense, but you start from a sorted list instead of a bank statement.
• Explaining forms. "What is a 1099-NEC and how is it different from a 1099-K?" is a great question for a chatbot. So is "What does line 30 on Schedule C mean?" Questions about what something means are where chatbots do best.
• Building a checklist. Describe your year in general terms (freelance design, a home office, one platform that pays through PayPal) and ask what records you'll need. Then compare its list with the IRS instructions.
• Preparing for your accountant. Ask it to turn your notes into clear questions. A tidy list of questions makes a paid hour with an accountant go a lot further.
• Checking your reasoning. Once you've done the math, ask it to explain each step back to you. If its explanation and your numbers disagree, one of you is wrong, and it's worth finding out which.

For the numbers themselves, use something that gives the same answer every time. Our freelance tax estimator takes your income, expenses and tax rates and gives you a rough annual and quarterly figure.

If you pay for an AI tool for your business, the subscription may be deductible too. Our post on whether AI subscriptions are tax deductible covers the rule and where it goes on Schedule C.

Where AI goes wrong with taxes

AI gets tax questions right more often than not. The trouble is that it sounds just as sure when it's wrong. Three patterns cause most of the problems.

Old numbers. Tax figures change every year, and some change more often. The IRS's Form 1099-K page says payment apps and marketplaces have to send you a 1099-K when your payments total over $20,000 in more than 200 transactions. Plenty of articles from the last few years quoted much lower thresholds, including $600, and a chatbot trained on them may repeat those. Your freelance income is taxable either way, whether or not a form arrives. If an answer includes a dollar figure, a percentage or a deadline, check it on IRS.gov before you use it.

Made-up answers. AI tools sometimes produce confident, specific, wrong answers, including citations to rules that don't exist. The IRS takes this seriously enough that its own guidance to tax professionals, discussed below, uses the industry's word for it: "hallucinations."

Your situation. A chatbot answers the question you typed. It doesn't know you moved states in June, that one client paid you through a platform, or that your spouse also freelances. You can tell it, but every detail you add is more sensitive information handed over. ChatGPT will happily tell you your home office deduction looks fine. So will your cousin. Neither of them signs your return, and neither will be there if the IRS writes back.

What not to paste into a chatbot

A tax return holds nearly everything someone would need to pretend to be you: name, address, Social Security number, income, bank account and family. Treat a chatbot like a stranger who's very good with spreadsheets. Give it the numbers it needs and nothing it could use to impersonate you.

• Never paste: your Social Security number or ITIN, anyone else's (spouse, kids, contractors), bank and routing numbers, IRS account logins or PINs, or full photos of W-2s and 1099s.
• Strip before you paste: names and addresses on invoices and statements. "Client A, $4,200, design work" is all the AI needs.
• Check the settings: many AI tools let you stop your chats from being used to train their models. Turn that on before you paste anything.

The IRS draws the same line for professionals. Preparers face civil and criminal penalties for using or disclosing tax return information without authorization, and the IRS guidance covered below tells them to use only "secure, enterprise-approved AI" for client data. Those penalties are for preparers and don't apply to you typing your own numbers into a chat, but the caution is worth copying.

Using AI to file taxes: a safe workflow

These five steps get you the time savings and keep AI away from the parts it can't be trusted with:

1. Organize with AI. Export your transactions, remove the personal details and let it sort them into categories and spot gaps (no receipts for October?).
2. Learn with AI. Ask it to explain anything you don't understand, and ask for the IRS form or publication it's relying on so you can read the source.
3. Calculate with a calculator. Run the numbers in a dedicated tool or a spreadsheet. Keep the chat for questions.
4. File with software or a pro. Use tax software, IRS Free File or a preparer to produce and submit the return.
5. Keep the records. Save receipts, invoices and the final return. If the IRS asks, "the chatbot said so" isn't documentation.

A worked example. Say you're a freelance designer with $60,000 of profit after expenses, and you ask an AI assistant for your self-employment tax. The rate is 15.3%, but it doesn't apply to your whole profit. On Schedule SE, you first multiply your profit by 92.35%:

A confident answer can skip a step like that without saying so, which is why the math belongs in a tool you can check. Self-employment tax is also only part of the bill: income tax comes on top, and you'll likely owe quarterly estimated payments. Our guide to calculating freelance taxes walks through the whole calculation.

If your accountant uses AI: what the IRS told them

You might not use AI on your taxes at all and still have it involved, because your accountant might. On June 24, 2026, the IRS's Office of Professional Responsibility, which oversees accountants, attorneys and enrolled agents who practice before the IRS, published OPR Alert 2026-19, its introductory guidelines for responsible AI use. It doesn't create new rules. It explains how the existing ones apply. The parts that matter to you as a client:

• They have to check everything. Practitioners must review all AI-created work and verify facts, citations and calculations before it reaches you or the IRS. The alert tells them to treat AI-written text as drafts.
• They have to understand the tool. Competence now includes knowing how their AI works, where it makes mistakes and when its output isn't fit to use.
• Your data has to stay secure. Client information goes only into secure, approved AI systems, never into unsecured or public ones.
• The savings should reach your bill. If AI cuts the time a job takes, the alert says the savings should be passed on openly, and practitioners should tell clients what AI was used for. Billing you for hours that weren't spent can break the rules on fees.

Every professional who uses AI now faces that last question, and we looked at it from the freelancer's side in our post on whether to charge less if you use AI. As a client, it's reasonable to ask your accountant two things: do you use AI on my return, and how do you protect my data when you do?
