TaxGPT has grown fast. It says more than 80,000 professionals use it, it holds a SOC 2 Type II certification, and its Cowork agents now prepare returns inside the tax software your firm already runs. If you are weighing it against the tool you use now, start with the problem you are buying for.
Bizora and TaxGPT answer that differently. Bizora gets you to a defensible, citation-backed answer across tax and audit questions, with the reasoning laid out where you can see it. TaxGPT pairs AI research with return review, return preparation and a persistent client record.
This comparison covers what each platform does, where it stops, and which firm it fits. The choice comes down to where your hours go. Every TaxGPT detail comes from TaxGPT's own published materials, and the figures TaxGPT reports about itself are labeled as its own.
Note: All vendor information is true as of October 2026 and should be verified independently.
| Comparison factor | Bizora | TaxGPT |
|---|---|---|
| Best for | You spend your hours on research, gray-area positions, and tax and audit questions you must document | Your bottleneck is return volume, and you want research, review and preparation on one platform |
| Research experience | Ask in plain language, choose Fast, Standard, Deep or Web Search, and see the authorities behind each answer. Audit Research is separate | Ask in plain language and get cited answers drawn from the Internal Revenue Code, Treasury Regulations, IRS guidance and court cases |
| Coverage | Federal, all 50 states, international tax (GILTI, FDII, Subpart F, treaties, Pillar Two, EU VAT) and audit standards (PCAOB, GASB, AICPA, Yellow Book, FAR) | Federal, all 50 states, territories and local questions, treaty questions, and Canada at the federal and provincial level. Matrix compares jurisdictions side by side |
| Seeing the reasoning | View Steps shows which authorities were used, how they connect and why the logic holds | Every answer shows its sources. TaxGPT reports a 0% source hallucination rate in its own benchmark |
| Client documents | Vault: upload returns, K-1s, notices and more, then ask across several files. No persistent client profile | Document upload (PDFs and images) plus Client Intelligence, a persistent record of each client's entities, history and prior-year positions |
| Drafting | Create Memo and Create Email keep your citations, and you edit in Canvas | Tax Writer drafts memos, IRS notice responses, client emails and engagement letters |
| Return review and preparation | No | Agent Andrew reviews returns (Pro plan). Cowork prepares them (Pro Plus plan) |
| Integrations | Claude, ChatGPT, QuickBooks, Xero, Truss and an MCP server. API billed per request | Cowork works inside Drake, ProConnect, UltraTax, CCH Axcess and Lacerte |
| Human review | Advisory Group: a credentialed tax professional reviews and signs off on research, positions and memos | No review service |
| Security | Encrypted in transit and at rest, no training on your data, SSO. Working toward SOC 2 | SOC 2 Type II certified |
| Price | $29.99, $69.99 or $119.99 per user per month | Not published. Pro, Pro Plus and Enterprise plans, all through a demo |
| Free trial | 7 days, no credit card | Free trial, but a live demo comes first |
Bizora is an AI tax research platform that shows you how it reached an answer, so you can check it against the authority. You ask in plain language with your client's facts, and you get an answer you can defend in a review. It also answers audit questions, analyzes client documents, and drafts memos and emails, so one platform covers the work before and after the answer.
A tax engine built on statutes, regulations, administrative guidance and case law powers every answer. It handles questions where the outcome depends on your client's facts, entity structure, jurisdiction or transaction, from a quick Code check to a multistate or cross-border analysis. You use it in the AI Assistant, or reach the same engine through integrations, an API and an MCP server.
Herbert Kyles, a Vice President and Wealth Advisor at Farther Finance Advisors, used Bizora to settle a five-year-old residency question for a prospective client with $10M in assets. In his words, "5 years of contemplation solved in 5 minutes using Bizora." Thirty minutes later, the couple agreed to move all $10M over. Read the Herbert Kyles case study.
TaxGPT is an AI platform for tax and accounting professionals that combines research with the work around it. Research, documents, drafting and return work stay connected through a persistent client record, and the same platform reviews and prepares returns. It is aimed at firms that want the whole workflow in one place.
Its research assistant answers tax questions in plain language with the sources listed: the Internal Revenue Code, Treasury Regulations, IRS guidance and court cases. Coverage runs across federal, state, territorial and local questions, plus treaty questions and Canada at the federal and provincial level. It is SOC 2 Type II certified.
TaxGPT also sells in tiers. Pro covers research, writing, Matrix, Client Intelligence and Agent Andrew. Pro Plus adds Cowork, tax preparation and a bookkeeping agent.
Run five checks on a real matter before you commit: coverage, answer quality, workflow fit, security and price.
Pull your last ten engagements and count the ones that touched another state, a foreign entity or treaty, Canada, or an audit standard. That number tells you how much coverage you need. If a tool covers your federal work and misses the rest, you end up buying a second subscription and verifying a second set of citations.
Bizora covers federal law, all 50 states and international provisions such as GILTI, FDII, Subpart F, Pillar Two and EU VAT, plus audit standards through Audit Research. TaxGPT adds Canadian provincial law and local jurisdictions.
Take one answer and open every citation. Confirm that each authority says what the tool claims and applies to your client's tax year. Then look for the path from sources to conclusion. That path is how you judge whether the answer holds.
Bizora's View Steps lays out that path, and the Advisory Group puts a credentialed reviewer on high-risk positions. Our post on whether an AI-researched tax position will hold up covers what reviewers check.
Follow one live matter from start to finish: documents in, research, memo, client email, return. Count the times you leave the tool or retype a fact. Every handoff costs time, so keep the tool with the fewest.
Check where the tool lives, too. If your team works in ChatGPT, Claude, QuickBooks, Xero or Drake, it will use a tool that connects to them and skip one that needs a separate login in busy season.
Ask for the answers in writing, because vendor reviews and client questionnaires will ask you for them. Find out what is certified today and what is in progress, whether the vendor trains AI models on your prompts or documents, how it encrypts data, and whether you can delete your files.
Bizora's security controls include encryption, role-based access and a no-training policy, and the team shares SOC 2 progress on request.
Price a real month of work instead of a single seat. Add up the seats, usage caps, per-return fees and API charges your workload would trigger, then divide by the hours the tool saves you on research, review and drafting.
Run the free trial on questions you already know the answers to. Bizora publishes its plans from $29.99 per user per month, and the 7-day trial needs no credit card.
TaxGPT covers federal law, all 50 states, territories, local questions, treaty questions and Canada at the provincial level. Matrix compares how several states treat an issue in one query. That reach matters for a practice that serves U.S. and Canadian clients. TaxGPT's feature set centers on tax, and audit or accounting standards research is not part of it.
Bizora's core database covers the Internal Revenue Code, Treasury Regulations, Revenue Rulings and Revenue Procedures, IRS Notices, Chief Counsel Advice, and Tax Court and federal case law, plus all 50 states. It adds international provisions such as GILTI, FDII, Subpart F, Pillar Two and EU VAT. Since August 2026, Audit Research covers PCAOB, GASB, AICPA, Yellow Book and FAR questions. Bizora covers select international codes without provincial Canadian detail.
Consider TaxGPT if you serve Canadian clients or compare state treatment often enough to want Matrix grids.
Consider Bizora if your firm does audit and attest work next to tax, or your clients have cross-border exposure beyond Canada.
The two tools back their answers differently. TaxGPT puts the sources on every answer, so you can check each one yourself. It also backs accuracy with measurement: TaxGPT reports a 0% source hallucination rate in a benchmark against frontier models from OpenAI, Anthropic and Google. That is TaxGPT's own result, so test it with your own questions.
Bizora links every answer to its sources too. View Steps then lets you read the path from the authorities Bizora consulted to the conclusion, including how they connect and why it holds. When a rule turns on conditions, the answer can include a decision tree you can walk a partner through. TaxGPT shows the sources but no step-by-step view of the logic.
Consider TaxGPT if a cited answer plus published accuracy testing is the confidence you need.
Consider Bizora if a partner or reviewer will ask how you got to the answer, not only where it is cited.
TaxGPT builds its document tools around the client. You upload IRS notices and get drafted replies, drop in prior-year returns to flag positions and risks, or upload multi-entity files to map ownership structures. Client Intelligence keeps that context between sessions, so you do not re-upload a client's history each time. TaxGPT accepts PDFs and images.
In Bizora, you drop the return into a Vault project and start asking. You group returns, K-1s, IRS notices and workpapers, ask across several at once, and have Bizora summarize them, extract figures, compare filings and flag differences. Vault accepts Word, Excel and CSV files as well as PDFs and images, but it does not build a persistent client profile.
Consider TaxGPT if you want client context to carry between engagements.
Consider Bizora if you want research and review to start from the documents you already have, in whatever format they arrive.
Research reaches the client as a memo, a notice response or an email. TaxGPT's Tax Writer drafts all three from the same session, and client memory carries prior context into each draft.
In Bizora, you shape the output before you write a word. Create Memo turns your research into a formal tax memo, engagement memo, file note or summary in the structure you choose, with the citations intact. Create Email writes for the audience, tone and level of detail you specify, including a plain-language explanation for a client. You edit both in Canvas, then save them to your workpapers.
Consider TaxGPT if you want drafts built on stored client history.
Consider Bizora if you want to choose the memo format and the tone of each client email.
This is TaxGPT's clearest differentiator. Agent Andrew reviews returns on the Pro plan, and Cowork prepares them on Pro Plus inside the software your firm already runs: Drake, ProConnect, UltraTax, CCH Axcess or Lacerte. For a high-volume practice, that saves time in a different place than faster research does.
Bizora does not review or prepare returns. It is a tax and audit research platform, and it runs next to your tax software. For R&D credit work, Bizora includes a qualification tool connected to TaxHack Accounting Group, which handles the full study, documentation and filing when a client qualifies. TaxGPT runs R&D credit studies as a Cowork workflow.
Consider TaxGPT if return volume is your bottleneck.
Consider Bizora if research and documentation are where your hours go, and your tax software already handles preparation.
TaxGPT works through its web app, its mobile apps and Cowork inside the tax software listed above. Cowork also pulls documents from storage such as Google Drive, Dropbox, SharePoint and SafeSend. If your workflow lives in those products, you stay in one place.
Bizora works inside the tools you already use. It is in the ChatGPT App Directory and the Claude Connector Directory, connects to QuickBooks and Xero, and powers cited research inside Truss's Max AI, as the Truss announcement explains. Firms that build their own tools use the OpenAI-compatible API and MCP server, billed per request, and the free Skills Library adds procedures such as Form 1040 Reviewer and K1 Tie Out.
When a position carries risk, the Advisory Group adds a human check. A credentialed tax professional reviews and signs off on research, positions and memos, and returns a cited memo under your firm's name within a standard 48 hours. TaxGPT offers no equivalent service.
Consider TaxGPT if you want preparation and review inside your existing tax software.
Consider Bizora if you want research inside the assistants and software you already use, or a credentialed second opinion.
TaxGPT has the stronger security attestation today. It is SOC 2 Type II certified, encrypts data in transit and at rest, hosts on AWS and Azure with U.S.-based processing, redacts personal information automatically, applies role-based access and audit trails, and never trains on client data. A client or insurer that asks for a completed audit report gets one.
Bizora encrypts data in transit with TLS and at rest with AES-256 or equivalent, applies role-based and least-privilege access, supports SAML single sign-on through Microsoft Entra ID, and does not use your prompts or documents to train AI models. You control the documents you store and can delete them at any time. A completed SOC 2 report is not available yet. Audit readiness is in progress, covering security policies, risk management, vendor oversight and control testing.
Consider TaxGPT if a completed SOC 2 Type II report is a requirement today.
Consider Bizora if its published controls meet your review, or you want to see its SOC 2 progress, which you can request at admin@bizora.ai.
TaxGPT does not publish prices. Plans are Pro, Pro Plus and Enterprise, and every plan starts with a demo and a custom quote. Pro is aimed at solo practitioners and includes research, Tax Writer, Matrix, Client Intelligence and Agent Andrew. Pro Plus adds Cowork, tax preparation and a bookkeeping agent, and Enterprise adds unlimited client entities, in-person onboarding and enterprise security. Ask for a written quote that names what each plan includes and any per-return fees.
Bizora publishes three per-user plans: Essential at $29.99 a month, Pro at $69.99 and Pinnacle at $119.99. Essential includes unlimited Standard Research and Vault access, with daily caps on advanced research. Pro removes the caps and adds unlimited Audit Research. Pinnacle adds priority support, early beta access, quarterly strategy reviews and team training. API and MCP use is billed separately on prepaid credits: $0.24 per Fast request, $1.50 per Deep request and $0.65 per Audit request, with no minimum and no contract.
Consider TaxGPT if return review and preparation justify a quote-based price.
Consider Bizora if you want the lowest published per-seat price for research and drafting, or deeper research and audit coverage on one subscription.
Choose Bizora if your practice mix crosses tax and audit work, you want research you can pull into an existing tool through an API or MCP connection, or you want published pricing and a trial you can start today.
Choose TaxGPT if return volume is your bottleneck, you serve Canadian clients, or a completed SOC 2 Type II report is a requirement before you sign.
Some firms will want both: TaxGPT for return review and preparation, Bizora for the research, audit-standards work and documentation behind your positions. Price the second tool against the hours it removes. For another comparison, read Bizora vs Marble.
