For tax advisory firms, tax law teams, and accounting firms handling complex client work.

Most AI tax tools begin with a question. TaxSig begins with the engagement.

Built for client deliverables. Not just answers.

Tax work worthy of your firm’s name. Work product your firm can trust.

TaxSig’s supervised AI agents drive each engagement from a tailored PBC to near-client-ready work product—backed by a frozen record of verified facts and law, independently challenged analysis, and a complete review trail linked to primary sources.

One governed tax engagement

A better service model

Complex tax work should move faster without thinning the evidence or review behind it.

TaxSig gives every matter a disciplined operating path, so professionals spend less time reconstructing the work and more time exercising judgment.

The AI should work silently behind the client deliverable. Only the leverage should be visible to the firm.

01

Expand delivery capacity

A coordinated agent team advances research, fact development, analysis, and drafting in parallel.

02

Reduce review drag

Claims arrive with their support, assumptions, and unresolved judgments visible to the reviewer.

03

Deliver consistently

The same firm-defined workflow and quality gates govern every matter, team, and deliverable.

04

Keep judgment human

Professionals decide the positions. TaxSig preserves what they decided, why, and on what record.

How TaxSig works

A matter moves through gates, not guesses.

TaxSig starts with client intake and ends with partner-reviewable work product—and the evidence record behind it.

01

Run the client evidence loop

TaxSig agents create a tailored PBC, collect supporting materials, test the responses, and build a source-linked fact record.

Gate: facts verified?
02

Verify the law

Agents gather relevant authority, preserve the operative text, and verify what may support the analysis.

Gate: law verified?
03

Coordinate the agent team

Specialized agents test the same record from defined roles to expose conflicts, gaps, and weak support.

Gate: position supported?
04

Bring judgment to review

The firm receives near-client-ready work product with the verified evidence, open issues, and judgment trail attached.

Professional approval

At any gate, if the record is not ready, TaxSig does not improvise or assume. It produces a precise request for the missing evidence or stops for human judgment.

Inside the service provider

Specialized agents. One governed engagement.

TaxSig is an engagement system, not an answer engine. It produces firm-branded client deliverables while preserving the verified evidence, unresolved issues, and professional judgment that make the work reviewable and defensible.

One system, two layers

Immediate value on the surface. Trust underneath.

The firm experiences a faster path to a near-client-ready deliverable. Beneath it, TaxSig preserves the governed record that makes the work reviewable and trustworthy.

What the firm delivers

The work layer

A polished, firm-branded memo prepared for professional approval and client delivery.

  • Fewer handoffs
  • Less rework
  • More visible progress
What the firm retains

The trust layer

An immutable engagement record preserves the PBC record, source-linked evidence, working analyses, identified disagreements, and documented judgment trail behind the deliverable.

  • Evidence provenance
  • Sufficiency controls
  • Review trail

Trust by design

Every material conclusion travels with its support.

Evidence before inference.

Trust is not a disclaimer; it is the architecture. TaxSig makes the review record part of the work product: the sources, verified facts, identified gaps, and professional decisions that moved the matter forward.

Facts are verified against client evidence and representations. Legal support is verified against primary source text. The firm retains responsibility for professional judgment.
