The Problem

Before You Act On a Business, You Have To Trust The Tax ID Behind It

Whether you're onboarding a supplier, releasing a payment, validating an invoice, or preparing a filing — generic KYB tells you a business exists, but can't tell you if it's correctly tax-resident, if its tax documents are authentic, or if its data is valid. That's where the real exposure lives — a fraud loss and a tax penalty at the same time.

Fraud & Forged Documents

Shell entities, forged tax certificates, and AI-fabricated documents pass a surface check. Paying them is a direct loss — and manual review misses them.

DirectFinancial Loss

Wrong Tax Classification

If residency and tax status are wrong, so is the withholding, the VAT treatment, and the reporting. That's penalties, backup withholding, and disallowed VAT.

Missing & Invalid Data

A missing number, an invalid ID, or an incomplete profile stalls the workflow and triggers weeks of chasing the counterparty by hand.

The job: know the business behind every Tax ID is real, correctly tax-resident, and complete — and fix it automatically when it isn't.

Generic different half. Nobody solves the whole thing.

What It Verifies

8 Areas . 30+ Signals The Verification Generic KYB Can't Do

This is the depth — not a score. Every business behind a Tax ID is interrogated across eight areas, and the ones that set us apart are the ones no KYB tool runs: official tax identity, cross-signal consistency, and forensic tax document verification

And More Validations...

Our validation suite extends beyond these core services, covering additional checks and specialized business requirements.

This is why we're not KYB. A KYB tool runs the middle rows. Only TaxDo reads the tax documents forensically, triangulates tax identity, and does it globally — the checks that decide whether a business is safe to act on, not just real.

The Answer

One Product . Two Layers Verify, Then Cure.

Tax-native verification of the business behind every Tax ID — and dynamic, case-based remediation that fills any gap in real time, then re-verifies until it passes.

The job: know the business behind every Tax ID is real, correctly tax-resident, and complete — and fix it automatically when it isn’t. Generic KYB solves half; tax-form tools solve a different half.

Why It’s Unique

The Intersection Nobody Else Owns

Two crowded markets sit on either side of us — and each solves only half the job. We deliberately don’t compete as either.

Generic KYB / IDV

Verify the business exists and collect documents via branded flows.

Not tax-native — no residency, no tax-document reading, no tax classification.

Tax-Form Collectors

Collect W-8/W-9, validate TINs, calculate withholding — bundled with payments or reporting.

US-form-centric — no KYB legitimacy, no forgery/forensic depth, not global.

TaxDoTaxDo . Verify+
Tax Identity & Business Assurance

The intersection nobody else owns.

Verifies the business is legitimate and correctly tax-resident, reads its tax documents forensically, and cures the gaps — in one verdict, globally.

Tax-native + global + forensic + auto-cure. One product.

We don’t win by being a better KYB tool — that’s a red ocean of funded players. We win by owning the tax-native lane between verification and tax compliance, where the buyer’s real risk (act on the wrong or wrongly-taxed party) lives.

Verify+ is Tax Identity & Business Assurance. It verifies, cures, and assures the business behind every Tax ID: the tax-native way to know a company is real, correctly tax-resident, and ready to onboard, pay, invoice, and report. It runs 30+ checks across eight areas and produces one verdict with an audit-ready certificate.

Generic KYB tells you a business exists, but can’t tell you if it’s correctly tax-resident, if its tax documents are authentic, or if its data is valid. Verify+ adds the checks no KYB tool runs — official tax residency, cross-signal consistency, and forensic tax-document verification — globally, and then cures the gaps automatically. A KYB tool runs the middle rows; Verify+ runs the ones that decide whether a business is safe to act on, not just real.

Eight areas and 30+ signals: TIN & Registry Intelligence (official identity and residency), Business Identity, Email Verification, Phone Verification, Address Validation, Cross-Signal Consistency (catches shell patterns), Deep Search & Digital Footprint, and Tax Document Verification. The tax-native and forensic areas — official tax residency, country triangulation across TIN, address and phone, and forensic document reading — are the ones that set it apart.

It’s not only a missing tax number. When anything is missing, invalid, or off — the tax number or any issue with the business information around it — Verify+ triggers remediation. It works out exactly what that case needs, requests it from the counterparty through a fully branded link on your domain with automated reminders, and cures the record in real time as they upload — then re-verifies. Zero touch from your team.

Only what the case is missing. Depending on the case that can include the tax number, a tax document and proof, any supporting document, a legally-binding e-signature, IP address, and a digital signature certificate. Nothing generic is requested — the link is built dynamically for the specific case.

Forensically. Verify+ determines the document type, extracts and matches the tax ID, matches the address, checks cross-field consistency and the issuing country, and runs forgery detection and prompt-injection detection — confirming the document is authentic, and that it belongs to the business being verified. Shell entities, forged tax certificates, and AI-fabricated documents pass a surface check; they don’t pass this one.

Supplier and vendor onboarding, payments and payouts, invoicing and e-invoicing validation, reporting and filing verification, counterparty due diligence, and ongoing monitoring and re-verification — every workflow that depends on a counterparty’s identity, for AP, procurement, tax, compliance, and finance-ops teams.

One verdict plus audit-ready evidence and a certificate for every case, kept current over time. The record is safe to act on, correctly classified, and audit-ready by default — and it is re-verified on a schedule, with alerts when a counterparty’s status, record, or risk signals change.

Know the Business Behind Every Tax ID.

Verify, cure, and assure — in one verdict, globally. 30+ tax-native checks across eight areas, forensic tax-document verification, and Zero-Touch Remediation that cures any gap without your team lifting a finger.
