Your product, tax-ready.
Add tax computation to your product without taking on the regulatory upkeep. We turn published tax rules into code you can call — and every answer comes back with the authority behind it.
We start where tax software usually gives up: K-1 allocations, multi-tier ownership, capital accounts, and filing validation.
Built for tax software, accounting platforms, CPA firms, and regulated financial teams.

On every answer
Regulation was written for humans, not software.
So your team stitches it together by hand. Every tax year.
- Hand-coded interpretations of tax rules
- Spreadsheet-based allocation workflows
- Manual regulatory updates
- Untraceable business logic
- Repeated validation every tax year
Research tells you what the rule says. Numeron makes the rule computable.
We start where tax software gives up.
Tangled ownership. Allocation rules. Elections. The part nobody automates.
A single partnership can distribute tax attributes through multiple entities before reaching the ultimate taxpayer. Numeron models the entire ownership graph, applies the relevant rules at each tier, and preserves the complete computation path.

- 02
Structure
Convert documents into typed nodes, relationships, citations, dependencies, and effective-date metadata.
- 03
Generate
Transform regulatory knowledge into executable, testable logic.
- 04
Compute
Run deterministic calculations against taxpayer or entity facts.
- 05
Validate
Check filings, allocations, reconciliations, elections, and compliance requirements.
- 06
Deliver
Return API responses, K-1 schedules, compliance reports, computation traces, or MeF-ready output.
An allocation run, end to end.
Structure in. Reconciled allocations, validation, and a full trace out.

Who builds on Numeron.
Tax software platforms
Embed tax logic without rebuilding and maintaining every regulatory dependency internally.
AI-native tax products
Add deterministic computation and validation beneath conversational or research-oriented AI.
CPA firms
Automate complex entity workflows while preserving review, traceability, and professional judgment.
Enterprise tax departments
Model entity structures, obligations, elections, and regulatory changes across internal systems.
Financial software teams
Integrate regulatory logic through APIs rather than hard-coding rules across multiple services.
Tax preparation infrastructure for financial platforms
Turn the data in your platform into a tax-ready customer experience.
Connect data
Bring permissioned income and expense data from your platform into a structured tax profile.
Identify gaps
Surface missing information and the tax requirements that apply to each customer.
Prepare workpapers
Produce preliminary workpapers for supported cases, ready for review.
For digital banks, fintechs, payroll platforms, and freelancer operating systems. Complex or taxpayer-selected cases route to qualified tax professionals, and your filing provider still handles submission.
Explore NumeronTax for platforms →One API. And an MCP interface.
Every response tells you what it checked and which rule it applied.
Tool-chain orchestration
Composable tools an AI agent can orchestrate across an end-to-end tax-compliance workflow.

Every number should be explainable.
Numeron does not return unexplained AI-generated answers. It produces deterministic outputs with evidence showing exactly how each result was computed.
- Source authority
- Effective date
- Rule version
- Intermediate calculations
- Validation results
- Reproducible trace ID
Built for the questions compliance will ask.
Private deployment. Human review in the loop.
These describe architectural support and design intent. Numeron does not claim SOC 2, ISO 27001, HIPAA, FedRAMP, IRS approval, or production e-file authorization. Compliance certifications will be listed here only once formally completed.
Tools we build alongside the platform.
Numeron builds developer tools and infrastructure that reflect our engineering philosophy — deterministic validation, auditability, and evidence-based automation.
An autonomous coding and verification project from the Numeron team, reflecting our approach to deterministic validation and evidence-based automation. Numeron is built with Zurdo.
Tax first. Then everything else.
Tax is where we prove it works. Financial regulation is the rest.
