How to fill in your organization's tax details (DIAN)

Watch the video2:01

In FEV & RIPS → Electronic invoicing you register the tax details the DIAN identifies your organization by. These details travel on every invoice you issue.

They must match your RUT exactly. If they do not, the DIAN may accept the invoice with an observation, or reject it outright.

Before you start

Have your RUT open. Every field on this screen comes from it.

The fields, one by one

Tax ID (NIT) : Digits only — no check digit, no dots or dashes. Example: 900123456.

Check digit : You do not type it. We compute it from the NIT and show it beside it. For NIT 900123456 the digit is 8. If your RUT shows a different one, the NIT was mistyped.

Legal name : The full legal name as it appears on the RUT — not the trading name.

Tax regime : One of three: IVA responsible (most clinics), not IVA responsible (independent professionals who do not charge IVA), or large taxpayer (only if the DIAN classified you so by resolution).

Economic activity (CIIU) : The four-digit code for your main activity, from the RUT. Example: 8621.

Municipality (DANE code) : The five-digit code for the municipality of your tax domicile. Example: 11001 (Bogotá D.C.).

Address, Phone, Email : As registered on the RUT. Invoices are delivered to that email address, so use one somebody reads daily.

The provider code (REPS) is not typed here

The DIAN requires the provider code on every health-services invoice, but this form does not ask for it: we take it from the ReTHUS/REPS verification on your professional profile — the same source as the code that travels in the RIPS. That way an invoice and its RIPS can never name two different providers.

If you have not done it yet, go to Professional Profile, enter your document and press Verify Credentials. Until one professional is verified, your invoices go out without the health-sector data — they are still issued, but incomplete against the regulation.

If it will not save

We check every field before sending anything to the DIAN. That is deliberate: a malformed value does not fail here, it fails later — the DIAN rejects all your invoices with a message that never names the offending field.
