Can AI do my taxes? | AI Does Help

Can AI do my taxes? Partly — and only as far as preparation goes. A general AI assistant can explain what a form or term means, turn a pile of receipts into a sorted table, and draft the questions you should take to a registered tax agent or the tax office. The return itself still goes in through official channels (myTax in Australia, IRS Free File or e-file in the US, Self Assessment in the UK, CRA-certified NETFILE software in Canada), and what ends up on that return stays your responsibility. Use AI as preparation help, not as a preparer.

Tools that work

Three general assistants handle this kind of AI tax preparation work. The prices below are what the companies' own pages showed when checked; plans and prices change, so check the current plan on the tool's site before you pay.

ChatGPT (OpenAI) — The Free plan includes unlimited text chats, with limited messages that include uploads, limited image creation, limited voice, limited deep research and limited memory. Paid individual tiers are Go, Plus and Pro. Plus costs USD 20 per month, billed monthly, with no annual billing option; OpenAI notes model availability and limits change over time. Go is the low-cost tier with higher limits than Free for image generation, file uploads and data analysis; OpenAI says purchases are in USD (local currency in some countries) and that it may adjust pricing over time. The Go price itself was not shown on the pricing page when checked, so check it there.

For documents, file uploads work on Free and paid plans within plan limits: 512MB per file, 2M tokens per text or document file, about 50MB for CSVs and spreadsheets, 20MB per image, up to 80 files every 3 hours for users generally, and 3 file uploads per day on Free. Before uploading anything sensitive, turn off "Improve the model for everyone" under Settings > Data controls; with it off, new conversations won't be used to train OpenAI models, and temporary chats are not used to improve models at all. OpenAI also states that ChatGPT can produce incorrect or misleading outputs, including fabricated quotes or citations, and advises verifying important information.

Claude (Anthropic) — Free is $0 and Pro is $17 per month with the annual discount ($200 billed up front), or $20 if billed monthly; Max starts from $100 per month. Prices exclude tax, and price and plans are subject to change at Anthropic's discretion. The Free plan includes chat on web, desktop and mobile, web search, file creation and code execution, memory and Artifacts; Pro adds more usage, Projects, more models and research. Usage limits apply to every plan. Claude accepts PDF, DOCX, CSV, TXT, HTML, ODT, RTF, EPUB, JSON and XLSX — XLSX needs code execution enabled — at up to 500MB per file, up to 20 files per chat, PDFs up to 1000 pages, with project files limited to 30MB each. Anthropic says users should not rely on Claude as a singular source of truth and should carefully scrutinize any high-stakes advice it gives.

Microsoft Copilot — Microsoft offers a limited free version of Copilot subject to available capacity and limits; Microsoft 365 Personal ($9.99/month) and Family ($12.99/month) include Copilot in Word, Excel, PowerPoint and Outlook with higher usage than free, and Copilot Premium is $19.99/month. Those are US prices on Microsoft's page, and in the Family plan the AI features are for the subscription owner only. The Excel integration is the useful part here, since most record-organising is table work. Microsoft says Copilot can make mistakes, misinterpret information or produce inaccurate results and advises reviewing and verifying anything it creates.

Is a free tier usually enough? For explaining terms, drafting questions and working through a handful of documents, yes — the free plans already include chat and file uploads within their limits. You'd want a paid plan mainly if you move a lot of files through the assistant regularly, since Free ChatGPT caps uploads at 3 per day, or if you want higher usage limits and Projects-style organisation.

A prompt to paste

Paste this into ChatGPT, Claude or Copilot and change the parts in square brackets:

I am preparing (not lodging) my [tax year] tax return for [country]. I am an [employee / sole trader / self-employed] person with income from [salary, bank interest, freelance work]. Here are my records: [paste a list, or upload the files].

1. Explain in plain English which of these records are likely relevant to my return, and why.
2. List the terms and form names I should understand before I start, with a one-line definition each.
3. Turn my receipts into a table: date, item, amount, the category it may fall under, and a confidence note (high / medium / low) for each category guess.
4. Flag every gap in my records, and tell me which official page or document would settle it.
5. Write five questions I should ask my registered tax agent, preparer or the tax office.

Rules: do not calculate my final tax, do not tell me the return is finished, and mark any number you inferred rather than read from my documents.

Two follow-ups that usually earn their keep:

"Now compare my table against the categories the official [country] tax authority page uses, and list where my labels don't match."
"Rewrite those five questions as a short email I can send to my tax agent, with a line for the documents I still need to attach."

How far AI gets you

Level: You or a pro. AI carries the reading, sorting and question-drafting; the return itself has to be lodged by you through the official channel or by a qualified preparer, because that is the moment the numbers become a legal submission and the accuracy obligation attaches.

What you still do

You own the numbers. An assistant can guess a category from a receipt line; only you know what the purchase was actually for. Anything marked medium or low confidence gets checked by hand.
You verify rather than trust. All four companies publish their own accuracy warnings. Treat every rate, threshold and deadline an assistant gives you as a lead to confirm on the official site.
You decide what to upload. Use the data controls first — ChatGPT's "Improve the model for everyone" switch, or a temporary chat — and describe figures in words instead of uploading documents when the material is sensitive.
You lodge, or you hire someone entitled to. That part differs by country.

Country	How the return actually goes in	Official rules and dates	Where AI still helps
Australia	myTax, accessed through a myGov account linked to the ATO, or the ATO app; available to all individuals and sole traders who lodge their own return	The ATO can pre-fill most information from employers, banks, government agencies and health funds by late July; the due date to lodge your own return is 31 October and most myTax refunds issue within 2 weeks (ATO)	Explaining pre-filled items, sorting deduction records, drafting agent questions
United States	IRS Free File or e-file; start at IRS.gov/freefile, because going directly to a partner's commercial website won't get you IRS Free File (IRS)	For the 2026 filing season (tax year 2025), IRS Free File covers taxpayers with 2025 adjusted gross income of $89,000 or less, through eight trusted partners each with its own eligibility rules; Free File Fillable Forms are available at any income level (IRS)	Explaining which forms apply, organising records before you open the software
United Kingdom	Self Assessment, online through HMRC	For 2025 to 2026: paper returns must reach HMRC by 11:59pm on 31 October 2026; online returns by 11:59pm on 31 January 2027, which is also the payment deadline (GOV.UK)	Plain-English explanations of Self Assessment terms, receipt tables
Canada	NETFILE, using tax software certified by the Canada Revenue Agency	NETFILE is open from February 23, 2026 to January 29, 2027; the CRA publishes a list of certified products each tax year (CRA)	Summarising slips and receipts before you enter them

When to bring in a qualified person instead: in Australia, only registered tax agents can charge a fee to prepare and lodge your return, they must be registered with the Tax Practitioners Board, and you can check registration on the TPB public register; you also remain responsible for the records you hand over, and if you want an agent's later lodgment deadline you should contact them before 31 October (ATO). In the US, anyone with a Preparer Tax Identification Number can be a paid preparer and skills vary, so the IRS directory of preparers with recognized credentials matters; and even when a paid preparer signs your return, you are ultimately accountable for the accuracy of every item — never sign a blank form. For UK and Canadian readers with anything beyond a straightforward return, the same rule applies: use the official guidance first and a licensed professional for the judgement calls.

Common questions

Can AI do my taxes if my return is simple?

It can get you ready faster: explain the terms, sort the receipts, tell you what to expect from pre-filled data, and draft the questions to ask. Whether your return is genuinely simple is a judgement about your own affairs, and if you're not sure, that uncertainty is the signal to use a registered agent or a credentialled preparer rather than a chatbot.

Can ChatGPT do my taxes, or only explain them?

Explain, organise and draft — not file and not sign. OpenAI says ChatGPT can produce incorrect or misleading outputs, including fabricated quotes or citations, and advises verifying important information, which is exactly why a tax figure it produces should always be checked against the official source.

Is it safe to upload tax documents to an AI chatbot?

Two separate questions sit inside that one: what the tool does with your data, and whether you need to upload at all. On the first, use the controls the tools publish — turning off "Improve the model for everyone" in ChatGPT, or using a temporary chat — and read the tool's current privacy documentation. On the second, you often don't need to upload: typing the figures as text gets you the same explanation.
