What Tax Guard does
Tax Guard verifies direct and indirect tax identifiers, confirms the entity behind them, and keeps records compliant over time — across global formats and jurisdictions.
Identifier qualification
Automatically checks whether a business partner's name and address match what the issuing authority holds for a given identifier — EU VAT, CNPJ (Brazil), Swiss UID, SIRET (France) and more — returning individual and consolidated qualification decisions.
Qualified checks against authoritative sources
Validates business and tax identifiers against issuing authorities and official registers such as VIES, with syntax and check-digit verification across global formats.
Continuous monitoring
Data quality rules run against records in your Data Mirror to detect changes in taxpayer status and keep records legally compliant over time, alongside real-time transactional checks.
Correction and enrichment
Automatically corrects format errors and enriches records with jurisdiction-specific tax reference data and metadata, keeping your tax data complete, accurate, and consistent.
Validation configuration and store
Configure data quality monitors with validation profiles to automate qualification, then review detailed results — decisions, timestamps, request identifiers, execution context, and identified defects — stored for audit and correction.
Headless API integration
A documented, headless API embeds real-time and batch tax validation into existing ERP, CRM, procurement, and e-commerce platforms — without custom code or system overhauls.
Why CDQ Tax Guard
A new category of tax data quality: continuous, global, and unified — built on CDQ's data quality and network foundation.
Continuous and embedded, not periodic and manual
Conventional checks against government portals are slow, error-prone, and unscalable. Tax Guard makes validation a continuous, preventative process embedded at the point of transaction.
Global coverage for direct and indirect tax identifiers
Legacy tools cover only regions, leaving compliance gaps. Tax Guard delivers consistent global coverage and supports requirements such as EU VAT Quick Fixes and U.S. sales tax rules.
One service, not fragmented workflows
Tax Guard merges tax identifier verification, status monitoring, and reference data lookup into a single service, replacing disconnected legacy tooling.
Part of the CDQ ecosystem
Tax Guard extends CDQ's data quality and network into the tax domain, complementing Data Quality Guard and AML Guard and drawing on shared, validated tax intelligence across the network.
How Tax Guard works
From a qualified check at the point of transaction to continuous monitoring of your records — configured once, automated from then on.

Run checks for business and tax identifiers against data provided by issuing authorities and official registers, confirming the entity by name and address.
Real time
Validation configuration

Frequently asked questions
What buyers ask about Tax Guard.
What is Tax Guard?
Tax Guard is CDQ's cloud-native service for validating, monitoring, and enriching the tax identifiers in your business partner data. It verifies direct and indirect tax identifiers against official registers and tax authority databases, confirms the entity by name and address, and continuously monitors for changes in taxpayer status — embedding tax compliance directly into your transaction workflows.
Who is it for?
Master data and governance leads who want a single, consistent source of truth for global tax identifiers; finance teams who need fewer payment rejections and accurate VAT reporting; procurement teams verifying suppliers before onboarding; and compliance and risk teams monitoring for non-compliant or changing tax identifiers.
How does it integrate with our SAP / ERP systems?
Tax Guard is delivered as a documented, headless API. It embeds real-time and batch tax validation into your existing ERP, CRM, procurement, and e-commerce platforms without custom code or system overhauls, so checks happen at the point of transaction as well as through ongoing monitoring.
Do we stay in control of our data and any changes?
Yes. Tax Guard works from a secure, customer-specific Data Mirror and monitors against trusted external sources. Insights and corrections are proposed, never enforced — you keep full control — and every decision is traceable to its source and time, stored with timestamps, request identifiers, and execution context for audit.
