Was your certificate restricted or are you on the 69-B list? Respond on time.
Without a digital tax certificate (CSD) you can't invoice or collect. And if you appear on the 69-B list, your clients may lose the tax effect of your invoices. In both cases deadlines run from the notice: what matters is to identify the real reason and respond with evidence.
- Assessment of the real reason: art. 17-H Bis, 69-B, not located or negative opinion
- Clarification request and a substance file per transaction
- Follow-up in the tax mailbox until the decision
If you can't invoice, your case gets priority · Confidential
How many days do you have left to respond, and what does waiting cost you?
Your legal deadline
It only counts weekends as non-business days; SAT holidays and vacation periods are also excluded, so confirm the exact date with us.
What you stop invoicing
While you can't invoice, every day counts.
For guidance only. The exact deadline depends on when the notice takes effect and the SAT's official calendar.
Every day without a certificate is collections on hold
You can't invoice or collect
Without a certificate you can't issue invoices or payment receipts, and your clients can't deduct what they buy from you until you invoice.
Your clients start to have doubts
If you appear on the 69-B list, your invoices may lose their tax effect for your clients, who will have to prove the transaction or correct their position. Many prefer to switch suppliers.
Deadlines are short
In the 69-B procedure you have 15 business days to submit evidence from the last notice. If you don't respond in time, you can be moved to the definitive list.
Deadlines run from the notice
The sooner we review your case, the more options you have to respond.

What clients usually ask us
How long until my certificate is reactivated?
It depends on the reason. For the art. 17-H Bis restriction, filing the clarification request with the right information is what lets you use the certificate again and has the authority decide within the legal deadline. In the review we tell you what to expect in your case.
What if my supplier is on the 69-B list?
If your supplier ends up on the definitive list, you have 30 days from publication to prove the transaction existed or correct your tax position. We review your suppliers and help you gather the evidence.
Do you guarantee reactivation?
No. Nobody can guarantee what the authority decides. What we do is identify the real reason, build the complete file and follow up closely. If your case has no reasonable way out, we'll tell you in the review.
I'm already on the definitive list. Can anything still be done?
Yes. There are remedies such as an administrative appeal or an annulment lawsuit, which take longer. We explain which option applies and, if litigation is needed, refer you to a specialist lawyer.
How much does it cost?
It depends on the scope and the information you already have. After the assessment we send a written proposal with a fixed fee and no hidden charges.
