The Tax Intelligence Platform · Built for CAS Firms

Tax intelligence foradvisory.

Client wants to buy their office building instead of leasing — what tax factors should shape the decision?
TaxFigure
The decision turns on a few levers: bonus depreciation and §179 on qualifying components, §168 cost recovery on the structure, mortgage-interest deductibility under §163(j), and the entity that should hold title. Upload the purchase agreement or a prior return and I'll pull the figures in.

The CAS Advantage

The gap that's slowing
your firm down

CAS firms are built around the numbers — but the most important client decisions are tax decisions. Buy the building, hire in a new state, time a big purchase: the answer isn't purely accounting. It's tax. TaxFigure closes that gap.

No tax desk to staff

The tax expertise you didn't hire for

Most CAS teams don't carry deep tax knowledge on the bench. TaxFigure puts a sourced answer in every team member's hands — not just the partner who's been doing it for twenty years.

Hours back

Stop losing hours to research

The gray-area tax question used to mean an hour of digging — or a day. Now it's a sourced answer in seconds, with current law, IRS guidance, and state authority already assembled.

Answer in the meeting

Stop handing it off and waiting

Send a tax question to an outside specialist and the client waits days — and the moment to advise passes. Answer it in the conversation, and stay the advisor they rely on.

One Engine · Every Service Line

Tax intelligence across every service line

TaxFigure answers tax questions — precisely, with sources — so your team can advise on the full picture without slowing down or bringing in outside help. From the document on the desk to the question on the call.

Documents

Read & interpret

Drop in a return, notice, schedule, or assessment and get the key figures, the flags, and the implications in plain language — before you advise.

CFO Advisory

Decision-ready

Buy vs. lease, a new-state expansion, a major purchase — the depreciation, §179, and entity factors that decide the move, while you're still in the room.

Controllers

Accounting × tax

How new-equipment depreciation flows into the quarterly estimates and cash flow, what a method change does to taxable income — less back-and-forth, a faster close.

Payroll

Multi-state, current

Add headcount in a new state and know the obligations before the first paycheck — FUTA/SUTA wage bases, supplemental withholding, and cross-state rules, kept current.

Sales Tax

Nexus, answered

Does the client have nexus here? Yes or no, with the threshold that triggered it — answered on the spot instead of sent to the preparer.

Document Intelligence

Read any tax document.
Understand it immediately.

Tax documents are dense, technical, and slow to interpret — even for experienced professionals. TaxFigure reads them for you, breaking down the key figures, flagging what needs attention, and explaining the implications in plain language.

See it read a document

A prior-year return

Understand a client's tax position, carryforwards, and planning opportunities before the CFO advisory meeting.

An IRS notice

Get a clear explanation of what the IRS is asking for, why, and the recommended response.

A depreciation schedule

See exactly how it flows into estimated tax payments and cash-flow planning — no decoding required.

A state assessment

Know whether the figures are correct, what triggered it, and what the client's options are.

A prior preparer's work

Taking on an inherited client? Surface gaps, missed deductions, and positions worth revisiting before you sign on.

How It Works Inside Your Practice

Sourced answers, not guesses

Your team asks the way they'd ask a colleague, drops in the documents they're already working from, and gets answers backed by current tax law — not a paragraph they still have to validate.

Backed by authority

Every answer carries its sources

Backed by current tax law, IRS guidance, and state-level authority. Share answers with clients confidently, or use them to inform advice — without spending hours validating sources.

  • Federal IRC & Treasury Regulations
  • IRS rulings, notices & published guidance
  • State & local authority across 50 states

Payroll tax

Multi-state is the hard part — rates shift, thresholds move, new states get added. Federal and state rates, FUTA/SUTA wage bases, supplemental and fringe-benefit treatment, and new-hire reporting, all kept current.

The advisory question that
used to take two days

The old way
2 days
The question goes to a tax preparer, sits in a queue, and the client waits. By the time the answer comes back, the moment to advise has passed.
With TaxFigure
10 min
Upload the last return, ask TaxFigure to walk the implications — depreciation options, entity considerations, the impact on estimates — and have the full answer in-house.

"We uploaded their last return, asked TaxFigure to walk through the implications, and had a full answer in under ten minutes. That's the kind of advisor we want to be." — Fractional CFO, multi-state CAS practice

Common Questions

CAS firm questions, answered

What client-advisory practices ask before closing the gap between accounting and tax.

Can my CAS team answer sales-tax nexus questions without a tax specialist?

Yes — ask whether a client has nexus in any state and the answer comes back with the threshold that triggered it, current rates by product and jurisdiction, and what's exempt, cited to the state authority. All 50 states, kept current.

What tax documents can TaxFigure read for advisory work?

Prior-year returns, IRS notices, depreciation schedules, and state assessments — uploaded as PDF, Word, Excel, CSV, or images up to 10 MB. Files are OCR-processed and the key figures, flags, and implications come back in plain language before you advise.

Does it actually cite its sources?

Every answer includes inline citations and a sources panel linked to primary authority — current tax law, IRS guidance, and state-level sources — so your team can share answers with clients confidently instead of spending hours validating.

How does it handle multi-state payroll questions?

Federal and state payroll rates, FUTA/SUTA wage bases, supplemental withholding, fringe-benefit treatment, and new-hire reporting requirements are kept current — so adding headcount in a new state starts with the obligations, not a research project.

Can the whole team work from the same client context?

Yes — each client is an entity workspace (individual, LLC, S-corp, partnership, or trust) shared with teammates at configurable access levels, with documents, insights, and conversation history in one place.

What does it surface beyond answers?

Insights grades each client's document coverage A–F with a what's-missing checklist, and Deduction Hunter scores deduction opportunities by confidence and dollar value — advisory leads, generated from the documents you already have.
