The best AI tax software

Free planNo
TurboTax is the household name in DIY tax filing, and Intuit has layered AI across the experience: smart deduction finders, real-time error checks, document import, and conversational guidance. The lineup spans free simple returns through Deluxe, Premium, and Self-Employed editions, with Live tiers adding on-demand expert help and Full Service handing the whole return to a tax pro.
It is the safest pick for most filers because of its breadth: every tax situation is covered, the interface is the most refined in the category, and support is extensive. The cost is higher than budget competitors, especially for investors and the self-employed, and the upsell flow is persistent. But for a guided, AI-assisted filing experience, it sets the standard.
What we like- AI deduction finder and real-time error checks
- Expert assist and full-service options
- Massive user base and polish
Watch out for- Pricing rises with complexity
- Upsells throughout the flow

H&R Block pairs AI with human expertise. Its AI Tax Assist answers tax questions in real time during the online filing flow, trained on vetted tax scenarios and tested by experts, while 60,000 tax professionals back it up in offices nationwide. Free Online covers simple returns, and paid DIY tiers add complexity and expert review.
The hybrid model is the differentiator: file yourself with AI help, or walk into an office when the return gets complicated. For filers who want AI convenience with a human safety net, H&R Block is the strongest combination. That flexibility is worth real money in a year with major life changes like a move, a new business, or a home sale.
What we like- AI Tax Assist with expert-verified answers
- Free online filing for simple returns
- Thousands of offices for in-person help
Watch out for- Free plan covers simple returns only

FlyFin is the most AI-native filing service for freelancers, gig workers, and the self-employed. Its AI analyzes your expenses to find every deduction, auto-fills return information from your documents, and a dedicated CPA prepares your federal and state returns from start to finish, with unlimited tax questions along the way.
The "man plus machine" model means you get automation plus a licensed professional reviewing the work, which matters when Schedule C deductions are where the money is. If your taxes are purely W-2, this is more than you need. For 1099 earners, it is the most purpose-built AI option here.
What we like- AI scans expenses for every deduction automatically
- Dedicated CPA prepares and files the return
- Quarterly tax help included
Watch out for- Built for freelancers and self-employed, not W-2-only filers
- Pricing requires the site

TaxGPT is not filing software; it is an AI tax copilot for accountants and tax professionals. Ask complex federal, state, or local tax questions and get cited answers from authoritative sources, with hallucination controls. It drafts client-ready memos and IRS notice responses, analyzes returns and financial statements, and its review agent flags errors and missed savings.
A free trial is available. For small tax firms and solo practitioners, it compresses research that used to take hours into seconds. DIY filers should look at the other tools here; TaxGPT is for the professionals who serve them.
What we like- Cited answers from the IRC, regulations, and case law
- Memo drafting and return review agents
- SOC 2 Type II certified
Watch out for- Built for professionals, not DIY filers
- Pricing is subscription-based

TaxAct is the value alternative to the big two. Its Free Edition covers qualifying simple returns at $0 federal, and paid tiers handle investments, rentals, and self-employment with guided filing and optional live expert help. The comparison chart on its own site positions it as the price leader against TurboTax and H&R Block.
It lacks the AI marketing of its rivals, but the fundamentals are solid: step-by-step guidance, document import, and guarantees. Budget-conscious filers who want a guided experience without the premium price should start here.
What we like- Free Edition for qualifying simple returns
- Live expert help add-on is affordable
- Strong accuracy and refund guarantees
Watch out for- Only about 40% of users qualify for the free edition
- Interface is plainer than TurboTax
Starting priceFree
Free planYes
FreeTaxUSA's model is simple: every federal return is free, no matter the complexity, with state returns at $15.99. Self-employment, investments, rentals, and home sales are all included at $0 federal. New AI form import pulls W-2 and 1099 data from a photo, and accuracy checks run in real time.
Support costs extra, with Deluxe and Pro Support tiers available as add-ons, but the core filing experience itself is complete without them. For filers who are comfortable working on their own, it is the cheapest way to file a complex federal return accurately.
What we like- Federal filing is free for everyone, including complex returns
- State is just $15.99
- AI form import and real-time accuracy checks
Watch out for- Support is an add-on
- State filing is not free

Cash App Taxes
Best for: Free federal and state filing
Visit cash.app
Starting priceFree
Free planYes
Cash App Taxes, formerly Credit Karma Tax, is 100% free for federal and state returns regardless of complexity. W-2s, 1099s, investments, even crypto sales are covered at $0, with accuracy and maximum-refund guarantees. Over 12 million returns have been filed through it.
The catch is the ecosystem: you need a Cash App account, and there is no expert-help upgrade path. For straightforward filers who want the absolute cheapest option with no qualification games, it is unbeatable.
What we like- Completely free federal and state filing for all situations
- Covers 1099s, investments, and crypto
- Refund up to 5 days early via Cash App
Watch out for- Requires a Cash App account
- No professional support tier
How we chose
We reviewed vendor product pages, feature documentation, and public reviews, plus tax-season coverage from publications like CNET and Forbes. We selected tools with genuine AI capabilities or AI-assisted filing experiences, from DIY platforms to professional copilots, and every tool had to be currently available with a working website. We did not claim hands-on testing.
Buying advice for AI tax software
Match the tool to your tax situation first, AI features second. W-2 filers with simple returns should start with the free options: Cash App Taxes, FreeTaxUSA, or H&R Block Free. Freelancers and the self-employed get more from FlyFin or TurboTax Self-Employed, where AI deduction-finding pays for itself. Investors and landlords need the premium tiers of TurboTax, H&R Block, or TaxAct.
Treat AI answers as a starting point, not a verdict. AI deduction finders and tax assistants are genuinely useful, but they can misread unusual situations. Review every AI-suggested deduction against your actual documents, and for high-stakes questions, confirm with a CPA. The tools that pair AI with human experts exist for exactly this reason.
Finally, watch the total price, not the headline. "Free" editions often exclude your situation, and state filing, expert help, and audit defense add up. FreeTaxUSA and Cash App Taxes are the most transparent about this; the big brands require more careful cart math. Add up federal, state, and any expert-review fees before you start, so the price you see at the end matches the price you expected at the beginning.
AI filing versus AI copilot: which do you need
AI filing tools do the return with you: they import documents, ask questions, find deductions, check errors, and e-file. The best of them learn from your prior returns, carrying forward information so each year gets faster than the last. TurboTax, H&R Block, FlyFin, TaxAct, FreeTaxUSA, and Cash App Taxes all work this way. AI copilots like TaxGPT answer questions and do research but do not file for you; they serve professionals and sophisticated DIYers who want cited answers to hard questions. Most individuals need filing software. If you are a freelancer with tricky deduction questions or a small firm doing research, add a copilot to the mix. The two categories are converging, with filing tools adding AI assistants and copilots adding workflow automation, so expect the line to keep blurring.
Frequently asked questions
What is AI tax software?
It is tax software that uses artificial intelligence to automate parts of filing: finding deductions, importing and reading documents, checking for errors, and answering tax questions in plain language. Some tools also use AI for year-round tax planning and professional research.
Can AI file my taxes accurately?
AI-assisted filing is generally accurate for common situations, and the major platforms guarantee their calculations. But AI can misinterpret unusual situations, so review the return before filing and consider expert review for complex returns.
Is there really free AI tax software?
Yes. Cash App Taxes and FreeTaxUSA offer free federal filing, and FreeTaxUSA's new AI form import is included. H&R Block and TaxAct have free editions for simple returns. Free plans cover filing; expert help usually costs extra.
Should freelancers use FlyFin or TurboTax?
FlyFin is purpose-built for freelancers, pairing AI deduction-finding with a dedicated CPA who files for you. TurboTax Self-Employed is a guided DIY option with broader brand support. Choose FlyFin if you want a CPA to handle it; choose TurboTax if you prefer to file yourself.
What is TaxGPT used for?
TaxGPT is an AI copilot for tax professionals, not a filing tool. It answers complex tax questions with citations, drafts memos and IRS responses, and reviews prepared returns for errors and missed savings.
