Digitalisation grants for SMEs and freelancers: what AEAT and Registro Mercantil will ask for

What you need to have to hand

1. Certificado digital (better the representative’s for companies) or Cl@ve active.
2. Estar al corriente with AEAT and Seguridad Social. If not, defer/regularise first.
3. Escritura y poderes registered at the Registro Mercantil and cuentas anuales deposited.
4. IAE correcto on your Modelo 036/037. Update if you change activity.
5. Budget or project brief you’ll submit (as required by the convocatoria).

Documentation

• Certificado AEAT de estar al corriente (PDF downloaded from sede.agenciatributaria.gob.es).
• Certificado Seguridad Social de estar al corriente (sede.seg-social.gob.es).
• Escritura of incorporation and current poderes (Registro Mercantil).
• Cuentas anuales deposited (latest ejercicio) or proof of depósito.
• Modelo 036/037 with the correct epígrafe IAE.
• DNI/NIE of the representative and poder de representación if a third party files.
• Declaración de minimis and presupuestos/ofertas from the provider (if requested by the convocatoria).

Step by step

1. Go to sede.agenciatributaria.gob.es > Certificados and download the “estar al corriente” with your electronic signature.
2. On sede.seg-social.gob.es > Empresas > Informes y certificados, download the certificado de estar al corriente.
3. Visit sede.registradores.org or registradores.org and order a nota simple, copia simple of the escritura and the current poderes. Order copies if needed.
4. Check your IAE. If you must change/add an epígrafe, file Modelo 036/037 at the AEAT site and save the receipt.
5. Verify your cuentas anuales are deposited. If not, file the depósito online and keep the receipt.
6. Submit the application on the convocatoria site (e.g. sede.red.gob.es/procedimientos/kit-digital). Fill the form, attach PDFs and sign.
7. If there’s a requerimiento de subsanación, upload the missing items within 10 días hábiles from the notification. Don’t leave it to the last day.

Time-saving tricks

• Use the representative’s certificate for companies: fewer signature errors.
• Keep PDFs under 10 MB and name them clearly ("poderes_sociedad_2026.pdf").
• If the Registro is slow, request the nota simple in the afternoon; it often performs better then.
• Keep receipts of everything (download and export all justificantes to PDF).
• If you’re tight on minimis, request only what won’t push you over the cap.

Common mistakes that will mess up your application

1. Active debt with AEAT/Seguridad Social: direct inadmission.
2. Signing with the wrong certificate (natural person instead of company representative): signature error and failed registration.
3. IAE/CNAE mismatch with the aid line: denial or endless subsanación.
4. Accounts not deposited: process blocked until you regularise at the Registro Mercantil.
5. Missing the subsanación deadline (10 días hábiles): application archived.
6. Submitting to the wrong convocatoria site: always file on the official sede listed in the bases, not on third-party sites.
