Verified Certificate of Tax Status
You upload the certificate and Singula cross-checks it against the SAT registry. You get an authenticity verdict and the taxpayer’s current status.
Singula reads the certificate and confronts it with the SAT registry.
The SAT registry is the official source of every taxpayer’s status. Singula extracts the certificate data and cross-checks it against that registry. The answer carries the verdict and the current status, in seconds.
The cross-check ends in a verdict
Every certificate falls into one of three states against the SAT. The verdict arrives with the taxpayer status.
Genuine
The certificate data matches the SAT registry.
With discrepancy
The certificate and the SAT registry disagree. Each difference is flagged.
Not found
The RFC on the certificate does not exist in the SAT registry.
Beyond the verdict, each check returns whether the taxpayer is active, suspended or cancelled with the SAT. A genuine certificate can belong to a suspended taxpayer.
Every certificate is also searched in the padrones the SAT publishes: firm debts, unlocated taxpayers and simulated operations. Findings arrive with their publication date, and anything already resolved in the taxpayer’s favour comes flagged as such.
What the cross-checked certificate carries
Alongside the verdict comes the taxpayer’s fiscal profile, already confronted with the SAT registry.
Taxpayer identity
Name or company name, RFC and whether it is an individual or a company.
Tax address
The address on record with the SAT, exactly as it appears on the certificate.
Economic activities
The declared activities, each with the share it represents.
Regime and obligations
The active tax regimes and the obligations the taxpayer carries.
How it works
The certificate arrives
Your customer uploads it from your product, or your team adds it to the file. Photo or PDF.
It is read and typed
The certificate data is extracted and it is identified as an individual or a company.
Cross-checked with SAT
The extracted data is confronted with the SAT registry, value by value.
The verdict comes back
Genuine, with discrepancy or not found, with the current status. It all lands in the file.
Two ways to use it
The same cross-check, whichever way the document enters your operation.
Inside the document engine
Upload any document and the engine handles it. When it recognises a certificate, it cross-checks it with the SAT on its own.
As a focused check
Send the certificate to verify and get back the verdict and the taxpayer status. One step, one answer.
Use it directly (the value in the body) or on a customer file. Same response.
What stays on your side
Singula hands over the verdict and the taxpayer status. The decision on each file stays with you.
- The certificate arrives with its onboarding checklist already evaluated: current fiscal year, issued within the last 90 days, activity page present, taxpayer active and off the padrones.
- Every check is stored with its date in the taxpayer file, available for audit.
- The acceptance policy belongs to your company. We hand over the verdict and the status; what you do with a discrepancy is set by your manual.
- The privacy notice and the holder’s consent stay on your company’s side.
Frequently asked questions
Singula extracts the certificate data and cross-checks it against the official SAT registry. The verdict (genuine, with a discrepancy or not found) comes from that cross-check with the official registry, not from the document you were handed.
Yes. The same check runs for both. The taxpayer type is identified automatically and the matching registry is cross-checked.
Whether the taxpayer is active, suspended or cancelled with the SAT at the time of the check. It is separate from the verdict: a certificate can be genuine and still belong to a suspended taxpayer.
They are the lists the SAT publishes: taxpayers with firm, cancelled or unlocated debts, and those flagged for simulated operations. Every certificate is searched there and findings arrive with their publication date.
