Blue J: AI tax research that shows its sources

Our verdict: Blue J is built for one job -- tax research -- and it does it with the sources attached. Ask a federal or state-and-local tax question in plain English and it returns an answer with the Code sections, regulations, and rulings it relied on, linked inline so you can check them. State and local taxes, or SALT, are the taxes a state or city charges on income, sales, and property. Pricing is published for solo use: $1,498 per year for one user, with Team pricing by quote. There is a 7-day free trial with no credit card, and the vendor holds SOC 2 Type II (an independent audit of its security controls). If your drain is losing an afternoon digging through the Code and regs from scratch, this aims straight at it.

The short version:

What it is: an AI tax research tool that answers US federal and state-and-local (SALT -- state and local taxes) questions and cites the authorities inline.
What it costs: published Individual plan at $1,498/yr per user for a sole practitioner; Team pricing by quote. 7-day free trial, no card. Pricing checked 2026-07-24.
The point of difference: every answer comes with its sources shown, so you verify the law yourself instead of trusting a black box.
Security: the vendor reports SOC 2 Type II. Still confirm data-handling and §7216 duties before real client facts go in.

Blue J is an AI tax research tool that answers US federal and state-and-local tax questions with the sources cited inline, on a published Individual plan at $1,498 per year per user with a 7-day free trial.

What does Blue J actually deliver?

You type a tax question the way you would ask a colleague, and Blue J gives you a written answer with the authorities it used linked right in the text. It covers US federal tax and state-and-local (SALT) tax, so multi-state work is in scope. Because the sources sit next to the answer, you can open each one and confirm it says what the tool claims.

The standing caveat is the professional one. AI research output is a draft, not a signed conclusion. Read the Code sections and rulings it cites, confirm they support the answer, and make the call yourself. The point of citation-backed research is that it makes that check fast, not that it removes it.

What does it cost?

Blue J publishes a price for solo use: the Individual plan is $1,498 per year for one user, aimed at a sole practitioner. Team pricing is by quote, so a multi-seat firm books a call for a number. Before you pay anything, a 7-day free trial with no credit card lets you run your own real questions through it. The vendor also reports SOC 2 Type II, an outside audit of its security controls. Pricing checked 2026-07-24 at bluej.com; confirm current terms and what the Individual plan includes before you subscribe.

What about confidentiality?

Research still touches client facts. A tax question often carries the client's situation with it, so treat it like protected data. You stay responsible for the work under IRS Circular 230, and its due-diligence and competence duties do not move to the tool. IRC §7216 -- the federal rule that makes it a crime for a tax preparer to use or share a client's return information without consent -- can apply the moment real return details go into an outside system. The GLBA Safeguards Rule and the IRS-required WISP (Written Information Security Plan -- the written data-security plan every tax firm must keep) mean you check how the tool handles data first. Blue J reports SOC 2 Type II; still get its data-handling and model-training terms in writing and confirm it does not train on your data. Our ethics and confidentiality guide has the checklist, and a pro from our find-a-pro directory can run the review. This site is educational only -- it is not tax, accounting, or legal advice.

Who is it right for?

Strong if…

Tax research eats real hours in your week and you want the sources handed to you.
You handle multi-state work -- the SALT coverage earns its keep.
You want to trust but verify -- inline citations let you check every answer.
A 7-day free trial on your own real questions is how you want to decide.

Maybe not if…

You mostly need bookkeeping or close automation -- this is research, a different job (see the tools we compare).
Your research volume is light enough that $1,498/yr would sit idle.
You need a full tax-prep or practice-management platform -- pair it with one like TaxDome rather than expecting Blue J to do that.
You want one flat team price today -- Team pricing is quote-only.

Common questions

How much does Blue J cost?

The published Individual plan is $1,498 per year for one user, aimed at sole practitioners. Team pricing is by quote. A 7-day free trial with no credit card lets you test it first. Verify at bluej.com.

What is SALT, and does Blue J cover it?

SALT means state and local taxes -- the income, sales, and property taxes that states and cities charge. Blue J answers both US federal and SALT questions and cites the authorities inline.

Does Blue J show where its answers come from?

Yes. Each answer links the Code sections, regulations, and rulings it used, so you can open and confirm them. You still own the final call -- read the sources before you rely on the answer.

Is my client data safe with Blue J?

The vendor reports SOC 2 Type II, an independent audit of its security controls. That is a good sign, not a full answer. Get the data-handling and model-training terms in writing, confirm no training on your data, and mind §7216 before client return facts go in.
