Of the 2024 transferable credit market was §45X

Purpose-built §45X compliance software exists today

The problem

Manufacturers are leaving hundreds of millions on the table.

§45X is the most powerful per-unit tax incentive for domestic clean energy and critical technology manufacturers in US history. It is automatic, per-unit, and transferable. Claiming it correctly is not.

Production must be tracked at the per-unit, per-component level - not as a share of revenue or facility spend.
FEOC restrictions under the OBBB (July 4, 2025) quarantine any supplier more than 25% Chinese, Russian, North Korean, or Iranian owned.
Form 7207 demands exact component categorization, production volumes, and sale documentation, with audit-defense files behind every claim.
Compliance work gets delegated across finance, ops, and legal with no single system of record.
Pre-construction decisions made without modeling credit impact quietly cost manufacturers millions before unit one ships.

Bottom line: Manufacturers that qualify for §45X are navigating this through spreadsheets, consultants, and siloed data. Nobody has built the software layer between the manufacturer and the IRS.

The product

Data in. Credits out.

A full-stack platform that turns raw production and supply chain data into verified, IRS-ready tax filings - and gives your team the workflow infrastructure to stay audit-ready year-round.

Data ingestion

Connect ERP, production management, and supply chain systems. Ingest per-unit production records, bill of materials, supplier data, and sales documentation automatically.

Verification engine

AI cross-references production data against §45X eligibility, flags FEOC supply chain exposure, validates component classifications, and surfaces gaps before filing.

Tax-ready output

Generate Form 7207, Form 3800, and audit-defense documentation. Export to your tax advisor or the IRS e-file system. Credit transfer attestations included.

The workflow layer

An operating layer for finance, ops, legal, and tax.

Bridging data ingestion and tax output is a collaborative operating layer - task delegation, AI guidance, and document generation in one platform.

Delegate across teams

Assign and track compliance tasks across finance, ops, legal, and tax - with clear ownership and full history.

AI guidance at each step

"Your Q2 battery cell production qualifies for $1.2M in §45X credits; here are the 3 supplier attestations needed to finalize."

Structured issue queue

Resolve FEOC exposure, missing production records, and classification mismatches in one queue - not over email.

Continuous audit trail

Audit-ready isn't a filing-week sprint. The trail is maintained throughout the production year.

Human in the loop

Expert review before anything is filed.

With a 20% IRS penalty regime on incorrect §45X claims, no manufacturer ships a multi-million dollar credit without a licensed expert reviewing it. We build that step into the product.

STEP 01
Platform
Ingests data, runs eligibility checks, flags FEOC exposure, drafts Form 7207 and supporting docs.
STEP 02
Team review
Finance, ops, and legal resolve flagged items inside the workflow. No spreadsheets. Full audit trail.
STEP 03
Expert sign-off
A tax attorney or CPA reviews the final package - calculations, FEOC attestations, Form 7207 - before anything leaves.
STEP 04
File or transfer
Approved documents go to the IRS or are packaged for credit transfer with buyer-facing FEOC attestations.

Compliance architecture

FEOC and IRS requirements, built in from day one.

FEOC under the OBBB

Suppliers >25% owned by Chinese, Russian, North Korean, or Iranian entities are auto-quarantined. Effective from the One Big Beautiful Bill, signed July 4, 2025.

IRS pre-filing registration

All §45X claimants must obtain a registration number via the IRS/CHIPS Pre-filing Registration Tool. We guide users through it and store the number for every future filing.

Form 7207 + Form 3800

Precise component categorization, production volumes, and sale documentation. Audit-defense files generated alongside every line of the form.

20% penalty regime, defended

Every claim ships with the source data, supplier attestations, and expert sign-off needed to defend it against an IRS challenge.
