This guide walks you through every stage of the process, from preparing your documentation to choosing a Digitalization Agent, with the practical advice we've built up from handling over 2,000 Kit Digital cases in Valladolid, Burgos, Palencia, Aranda de Duero, the Canary Islands, and the rest of Spain. On the islands, we handle both Kit Digital in Tenerife and Kit Digital in Las Palmas. This isn't a rehash of the official rules: it's a hands-on guide written by professionals who work with this process every day and know exactly where most businesses trip up.
Do it yourself: you follow each step in this guide — self-assessment, documentation, online application, choosing an agent, and implementation — and take on the deadlines, any requests to fix or complete your application, and the final justification.
Let us handle it: our Kit Digital team manages the entire case, from checking your eligibility for the grant through to justification with Red.es. See our official Digitalization Agent listing and, if you'd like to get started, let us handle your Kit Digital application for you.
Before You Start: Make Sure You Meet All the Requirements
Spending 15 minutes checking the eligibility requirements before you start the process can save you hours of wasted work. You can start with our Kit Digital calculator, which tells you your segment and how much you could be eligible for. Red.es checks every requirement electronically during the process, and any shortfall results in a denial that, while it can be resolved, means starting over and losing time.
The core requirements are: being registered as a business or self-employed professional with the minimum length of registration set by the call for applications (check the current rules for the exact period); having your registered tax address (domicilio fiscal) in Spain; being up to date with tax obligations with the Spanish Tax Agency (a certificate you can get online at aeat.es within minutes); being up to date with Social Security (certificate available at sede.seg-social.gob.es); not qualifying as an "undertaking in difficulty" under EU rules; not being subject to any of the prohibitions in Article 13 of Spain's General Subsidies Act (Law 38/2003); and not exceeding the cumulative de minimis aid ceiling set by Regulation (EU) 2023/2831.
One point that often causes confusion: communities of property (comunidades de bienes), civil partnerships without legal personality, and non-profit entities can apply for Kit Digital as long as they meet the other requirements. Temporary business consortiums (UTEs) and public companies, on the other hand, are excluded under the program rules.
Practical tip: get your Tax Agency and Social Security certificates before starting the online application, even though they're verified electronically anyway. If there's an issue (an outstanding payment, a deferral that was never formalized), it's better to find out and fix it beforehand than to get a denial after you've already spent time on the form.

Step 1: Register on Acelera PYME and Complete the Self-Assessment
The Acelera PYME platform (acelerapyme.gob.es) is the entry point for the whole process. You'll need to create an account if you don't already have one, then complete the digital self-assessment test, which evaluates your business's current level of technological maturity. This test is mandatory, and its result is attached to your application.
The self-assessment isn't a competitive exam: you don't need a high score to get the grant. Its purpose is to give Red.es a snapshot of where your business currently stands digitally. The questions cover areas such as online presence, use of management tools, cybersecurity, your team's digital training, and the level of process automation.
The most important advice about the self-assessment: answer honestly and accurately. Your answers should reflect your business's actual situation, not an idealized version or an overly pessimistic one. If you say you have advanced BI tools when you don't actually use them, or that you have no online presence at all when you actually run social media profiles, that inconsistency can cause problems later in the process.
Take your time. Don't rush through it or do it with distractions. If you don't understand a question, look into it before answering. The test takes 15-20 minutes to complete if you've prepared beforehand.
Step 2: Prepare Your Complete Documentation
Documentation is the stage where most applications get stuck. Document errors are the most common cause of requests to fix or complete an application, and each such request can add weeks to the process. The key is to get everything ready before you start the online application.
You'll need a valid digital certificate for the company's legal representative, or advanced-level Cl@ve, for the electronic signature. If your certificate has expired or is about to, renew it before you start. You'll also need: the company's articles of incorporation or, for self-employed professionals, your registration in the economic activities census; the legal representative's national ID (DNI) or foreign ID (NIE); certificates confirming you're up to date with the Tax Agency (AEAT) and Social Security (TGSS), which you can get online with your digital certificate; and a declaration of responsibility (declaración responsable) confirming compliance with all the requirements set out in the rules.
Organize all your documentation in a digital folder before starting the application. Check that names, tax ID numbers, addresses, and tax details match exactly across every document. A tax ID with one digit wrong, or a company name abbreviated differently on two documents, can trigger a request for clarification that delays the resolution by weeks.
One more tip: if your company's legal representative is different from the administrator listed in the commercial registry, make sure you have a valid power of attorney that's been properly registered. We've often seen this cause rejections in companies with more complex corporate structures.
Step 3: Submit Your Online Application
With the self-assessment done and your documentation ready, all that's left is the online submission. This step can only be completed when a call for applications is open; there isn't one right now. Once Red.es publishes the next call, you'll submit your application through its electronic portal (sede.red.gob.es). The form will guide you through the required fields: company identification details, legal representative's details, tax information, declarations of responsibility, and supporting documents.
Fill in every field with pinpoint accuracy. Your tax details must match, character for character, what's on your certificates and in the AEAT census. Upload your documents in the accepted formats (usually PDF) and check that every file has uploaded correctly before you sign.
Once the form is complete and the documents are attached, sign electronically with your digital certificate or Cl@ve. The system will generate a submission receipt with a registration number: keep it somewhere safe, as it's your proof that the application has been correctly registered in the system.
From this point on, Red.es will assess your application and issue a decision granting or denying the grant. Timelines vary depending on the volume of applications, but they typically range from several weeks to a few months. While you wait, you can use the time to evaluate Digitalization Agents and work out which solution categories you need, so you don't waste time once your voucher is approved.
Step 4: Choose Your Digitalization Agent and Formalize the Agreement
Once you receive a favorable decision granting the voucher, you have a set period to choose a Digitalization Agent and formalize the Service Agreement. This is arguably the most critical moment in the whole process, because the quality of the implementation and the success of the justification depend directly on the agent you choose.
The catalog of authorized Digitalization Agents is available on the Acelera PYME platform, where you can filter by category, location, and specialization. But don't just skim the catalog: look into the agents that interest you, visit their websites, check their references, and don't hesitate to ask for detailed information about their track record before signing any agreement.
Always ask how many Kit Digital projects the agent has completed and successfully justified, what exactly the proposed solution for your category includes, the estimated implementation timeline, what they'll need from you during the process, who handles the documentary justification with Red.es, and what support they offer after implementation.
The service agreement should clearly spell out the features you'll receive, the delivery timelines, each party's responsibilities, and the justification process. Don't sign an agreement with vague or generic descriptions: the more specific the document, the lower the chance of disputes later on.
Step 5: Implementation, Delivery, and Justification
Once the agreement is formalized, the agent begins implementing the solution. Your active involvement during this stage is essential: you'll need to provide content (text, images, business data), review intermediate deliverables, give timely feedback, and make sure the final result matches what was agreed and fits the real needs of your business.
Once the solution is implemented and delivered, the agent handles the documentary justification with Red.es. This justification includes technical evidence that the implementation actually took place, itemized invoices for the services, and documentation proving the solution meets the minimum requirements for the category you contracted.
Red.es will verify the justification and, if everything checks out, pay the voucher amount to the agent. During this stage, your responsibility is to keep all the project documentation, keep the solution up and running, and cooperate with the agent if Red.es requests clarifications or additional documents.
One important detail: the implemented solution must stay operational for a minimum period set by the call for applications (usually 12 months). If you take your website offline, uninstall the antivirus, or cancel the CRM before that period is up, you could be required to repay the grant. Plan for continuity from day one.
