Luxembourg SME Packages AI grant 2026: eligibility, process, timeline, pitfalls

Last updated 22 April 2026. Every fact in this guide is sourced from guichet.public.lu, the Luxembourg Ministry of the Economy, Luxinnovation, the Chamber of Commerce (cc.lu), and Paperjam. Where authoritative sources disagree or leave a gap, we say so.

TL;DR, the grant in 30 seconds

The SME Packages AI (operational since 11 March 2025) reimburses 70% of eligible costs on AI implementation projects worth €3,000 to €25,000 excluding VAT (HT). Maximum subsidy per project: €17,500 HT. The grant is run by the Luxembourg Ministry of the Economy, with mandatory pre-analysis through the House of Entrepreneurship (Chamber of Commerce) or eHandwierk service (Chamber of Skilled Trades, for craft businesses). You pay the service provider in full, then claim reimbursement after implementation. Typical wall-clock time from first appointment to reimbursement: 4 to 6 months. It is a de minimis aid under EU Regulation 2023/2831, so it counts against your €300,000 rolling-three-year state-aid ceiling. If you start work before Ministry approval, you are disqualified, no exceptions.

What the SME Packages AI actually is

The SME Packages portfolio is Luxembourg's fast-track, lightly-administered answer to five common small-business modernisation questions: going digital, going sustainable, going circular, tightening cybersecurity, and, since March 2025, adopting artificial intelligence. Each package is capped at €25,000 HT per project, reimbursed at 70%, and gated through a mandatory chamber-led pre-analysis.

The AI variant was announced on 4 July 2024 by Lex Delles, Minister of the Economy, SMEs, Energy and Tourism, alongside Sasha Baillie, CEO of Luxinnovation, at Luxinnovation's 2023 annual-report presentation. It went live operationally on 11 March 2025. It sits deliberately downstream of Luxinnovation's larger Fit 4 AI programme (which funds strategic assessments at up to €50k to €200k), SME Packages AI is for companies that already know what they want to build and need money to put an existing AI tool into production.

What it funds, in plain English: consulting, configuration, integration, and rollout of an AI solution delivered by an external service provider. What it does not fund: R&D, building your own model from scratch, internal-staff time, and ongoing subscription costs beyond the project window (more on this in the pitfalls section).

Legal basis. The grant operates under Commission Regulation (EU) 2023/2831 of 13 December 2023 (de minimis aid), implemented nationally via loi modifiée du 9 août 2018 on SME support and règlement grand-ducal du 12 octobre 2018 determining eligible expenses.

Who qualifies

Three boxes must be ticked, all of them, before anything else matters.

1. You must be an SME under the EU definition (Recommendation 2003/361/EC): fewer than 250 employees, and either ≤ €50M annual turnover or ≤ €43M annual balance-sheet total. Only one of the two financial thresholds needs to be met. Critically, the definition applies to the entité économique unique, if your company has partner or linked entities, the headcount and financials of the whole group count, not just your own.

2. You must be a Luxembourg-established business. Three sub-tests, all mandatory:

• You hold an autorisation d'établissement (business permit) issued by the Ministry of the Economy.
• Your siège social (registered office) is in Luxembourg.
• You carry out active operations in Luxembourg (implied by the pre-analysis requirement).

A Luxembourg-registered subsidiary of a foreign parent qualifies. A bare branch or franchise of a foreign company likely does not, unless it has obtained its own business permit and RCS registration. If you are unsure, raise it in your first pre-analysis appointment.

3. Your project must fit the cost window. Between €3,000 and €25,000 HT, quoted by an external service provider. Projects below €3k and above €25k HT are automatically outside scope. If your ambition is larger, the right instrument is Fit 4 AI, not this one.

There is no sectoral restriction written into SME Packages AI specifically, but the general SME aid law excludes primary agriculture, fishing, certain transport activities, and firms in financial difficulty. Heavily regulated sectors (banks, insurers) are usually ineligible under the broader framework. If your NACE code sits in any of these, verify with the House of Entrepreneurship before you invest time in an application.

How much money you actually receive

Flat 70% of eligible costs, reimbursed in one post-implementation payment. There is no size-based tiering, a micro-enterprise with 3 employees and a medium-sized firm with 200 both get 70%. There is no sector loading or regional bonus.

Two things to keep top of mind when modelling cash flow. First, you pay the service provider the full invoice up front; the 70% lands in your account afterwards, not during. Second, VAT is on you, the €3k and €25k bounds are both HT (hors TVA / excl. VAT). A €25k HT project actually costs €29,250 TTC out of your current account before any reimbursement arrives.

The process, step by step

The official guichet.public.lu page prescribes six stages. Real-world project timelines push each one a little further than the page admits, we flag the realistic estimates here.

Stage 1, Pre-analysis with the chamber (mandatory). You phone the House of Entrepreneurship (for most businesses) or the eHandwierk service at the Chamber of Skilled Trades (for craft businesses: entreprises artisanales) and book a meeting. The adviser assesses your current AI readiness, helps you identify priority use-cases, and starts shaping the application. This is not optional, guichet.public.lu is explicit: "L'entreprise doit obligatoirement passer par une préanalyse de la House of Entrepreneurship ou de la Chambre des métiers qui l'aide à remplir le formulaire de demande de subvention." Allow 1 to 2 weeks to get an appointment.

Stage 2, Choose your package and service provider. You pick a specific AI solution (a documented, internal-process use-case) and an external provider, and together you draft a quote (devis) in the €3 to €25k HT window. The provider does not need to be on a formal Ministry list for the SME Packages AI track (unlike Fit 4 AI, which operates a labelled-consultant network), but your chamber adviser will push back on vague scopes. Allow 2 to 4 weeks.

Stage 3, Submit the application. With the chamber adviser's help, the application file is assembled (form, devis, company financials, project description) and submitted, usually through MyGuichet.lu with LuxTrust digital-signature authentication, sometimes directly to the Ministry. A dedicated adviser is assigned to follow your case.

Stage 4, Ministry review and approval. The Ministry of the Economy's Direction générale Aides d'État et financement aux entreprises analyses and validates the application. Expect 6 to 10 weeks wall-clock. Published material typically says "4 to 6 weeks"; our read of practitioner reports is that 8 to 10 weeks is more realistic if the file needs even minor clarification. You must not start project work until you have the written approval in hand.

Stage 5, Implementation. The service provider delivers the AI solution. Typical range: 2 to 8 weeks, depending on complexity. You pay their invoice(s) as work progresses.

Stage 6, Evaluation and reimbursement. A closure meeting measures your satisfaction and the real business outcomes. The file is considered closed when this evaluation is documented. You submit proof of payment + delivery to the Ministry, which reimburses 70% of eligible costs to your business account. Plan for 4 to 8 weeks between "project complete" and "cash in the account."

Realistic end-to-end: 4 to 6 months from first appointment to reimbursement for a clean application. Plan for 6 months if your team has never done a Luxembourg grant before.

Timeline at a glance

What "eligible costs" really covers

The official scheme deliberately avoids publishing a line-item schedule. The pre-analysis and chamber-led file preparation are where eligibility is negotiated in practice. From our reading of the texts and from practitioners, here is the working map:

Clearly in scope:

• External consultant and service-provider fees for AI implementation
• One-time software setup and configuration costs tied to the AI deliverable
• Integration work (connecting the AI tool to your existing systems)
• Initial training and knowledge-transfer sessions that are part of handover

Grey zones, get them validated during pre-analysis:

• SaaS and licence subscriptions. The €3 to €25k HT window is a project window, not an annual budget. A twelve-month licence bundled into the initial implementation is usually fine; year-two and onwards ongoing licensing is not what the grant is for.
• Hardware. Equipment required to deploy the AI solution (e.g., an edge device, a specific sensor) is sometimes accepted if justified. A general IT refresh is not.
• Internal staff time. Not eligible. The programme funds external delivery, not your own payroll.
• Travel. Not explicitly addressed; assume it is out of scope unless confirmed.

Out of scope:

• R&D and novel-model development. If your plan is to train a custom LLM or publish research, Fit 4 AI or Aide à la R&D are the correct instruments, not SME Packages AI.
• AI projects that are effectively the construction of saleable product IP rather than adoption of existing tooling.

If in doubt, ask for written confirmation from your chamber adviser before the devis is finalised, post-hoc eligibility disputes are one of the most common reasons reimbursements get held up.

How SME Packages AI stacks with other Luxembourg grants

The core cumulation rule, taken straight from the general SME conditions: "Un projet ne peut pas cumuler différentes aides étatiques portant sur les mêmes coûts à moins que le plafond de l'intensité maximal des régimes en question demeure respecté", a project cannot combine multiple state aids on the same costs unless the maximum aid-intensity ceiling is respected. Because SME Packages already offers 70%, stacking another state aid on the same line items almost always breaches the ceiling.

In practice that means:

• SME Packages AI + SME Packages, Digital + SME Packages, Cybersecurity: allowed, if each is a separate project targeting different cost lines, and if each is completed sequentially (not run in parallel as one mega-project). Each is subject to its own €3 to €25k HT window.
• SME Packages AI + Fit 4 AI: allowed if they address genuinely different workstreams (e.g., Fit 4 AI pays for the strategic assessment, SME Packages AI pays for the implementation of a specific downstream use-case). The same activity cannot be paid twice.
• SME Packages AI + Fit 4 Digital: allowed, with the same different-workstreams caveat.
• SME Packages AI + Digital Europe / L-DIH vouchers: usually allowed (DIH vouchers are explicitly designed to be stackable), but declare all aid when you apply.
• SME Packages AI + Aide à la R&D: generally incompatible for the same project. R&D aid has its own higher intensity ceilings and reporting regime.

Everything cumulates toward the €300,000 rolling-three-year de minimis ceiling under EU Regulation 2023/2831 (threshold raised from €200k on 1 January 2024). Before applying, ask your accountant for a de minimis history report covering the past 36 months. If you are already at €270k, you only have €30k of headroom, not enough for a full €25k × 70% project that lands an €17,500 subsidy if you still have room for another SME Package afterwards.

Adjacent grants, when SME Packages AI is the wrong answer

Rough rule of thumb: if your project is under €25k HT, involves no research, and uses a service provider you already trust, SME Packages AI is the fastest path. Anything larger or more speculative belongs further up the Luxinnovation ladder.

Ten ways applications get rejected or reimbursements blocked

Most of these are avoidable with discipline. Every consultant we've spoken with rates the first one as the leading cause of outright disqualification.

1. Starting project work before Ministry approval. The effet incitatif (incentive effect) rule says the aid must change your behaviour, and you cannot change behaviour that has already happened. A signed contract, a deposit, a first invoice from the consultant, or even a public announcement can count as "starting." Wait for the written approval letter. No exceptions.

2. Passing €25,000 HT mid-project. Scope creep above the ceiling retroactively disqualifies the whole project. If the scope has to grow, either stop at €25k or restart as a Fit 4 AI application.

3. Skipping the pre-analysis. Applications that arrive at the Ministry without a documented House of Entrepreneurship or eHandwierk pre-analysis are declined on procedure, not merit. This is a non-negotiable gate.

4. Using an inappropriate service provider. Although there is no formal accredited-provider list for SME Packages AI (unlike Fit 4 AI), the Ministry expects a credible, specialised firm. Vague one-page quotes without deliverables, milestones, or itemised costs get flagged as "insufficient detail for evaluation."

5. Counting ongoing SaaS into the €25k. A €8k/year SaaS contract for three years is not a €24k project. The grant funds one-time implementation. Year-two subscriptions are your ongoing opex.

6. A purely technical pitch with no business case. Evaluators look for quantified efficiency gains, cost reductions, or revenue effects. Published signals suggest applications with a clear business case are materially more likely to clear review than those that dwell on the technology alone. Frame the project around the outcome, not the model.

7. Being part of a larger group without disclosing it. The SME definition is calculated at the entité économique unique level. A standalone Luxembourg subsidiary with 40 employees may still fail if the parent group pushes it over 250 or €50M. Disclose upfront.

8. De minimis ceiling already hit. Other state aid you received in the previous 36 months counts. If cumulated de minimis is already at or near €300k, you will be refused on ceiling grounds even if every other criterion is met.

9. Missing LuxTrust or RCS paperwork. An expired LuxTrust certificate, a signatory who is not the gérant or authorised director per RCS, or a mismatched company number triggers automatic rejection before evaluation. Dry-run the digital-signature flow a week before submission.

10. GDPR not addressed for personal-data projects. If your AI processes customer records, employee data, or any personal information, a Data Protection Impact Assessment (DPIA) is expected as part of the file. An omission is usually a request-for-clarification rather than an outright refusal, but it adds 2 to 4 weeks to the timeline. Treat this as a day-one task, not an afterthought. The EU AI Act Article 4 (AI-literacy duty) has been in force since 2 February 2025 regardless of whether you take the grant; August 2026 brings national penalties, so AI literacy training for affected staff is in scope and fundable.

Two Luxembourg businesses that have actually done it

Published beneficiary case studies for SME Packages AI specifically are thin on the ground, the programme is only 13 months old at time of writing, and no dedicated AI-package testimonial has been surfaced publicly yet. The closest public examples sit under the broader Fit 4 / AI support umbrella:

Fischer (bakery). The Luxembourg bakery chain deployed an AI-based order-recommendation tool. Reported results (published via House of Entrepreneurship communications): +4% sales, -1.5% waste, payback within three months. A textbook SME Packages AI fit in shape and scale, an existing AI tool applied to one clearly-defined operational process, with measurable business outcomes from day one.

Cebi International (electromechanical components, automotive and appliances). Built an operational digital twin incorporating predictive AI, in partnership with the University of Luxembourg SnT centre. Reported results: -60% scrap within six months, +20% equipment efficiency within one year. Larger in ambition than the SME Packages AI envelope (so funded through Fit 4 AI / Aide à la R&D pathways rather than SME Packages AI), but it gives you the shape of what "serious" AI adoption in a Luxembourg SME looks like end-to-end.

The pattern both cases share is the one that matters for your own application: concrete process, measurable before/after, external partner doing the heavy technical lifting.

What to watch in the rest of 2026

A few moving pieces that may affect how you plan.

Luxinnovation's 2025 activity report is expected in the May to July window and should contain the first published usage figures: applications received, approval rate, average subsidy, sectoral mix. Today those numbers are not public.

EU AI Act national penalties activate on 2 August 2026. The AI-literacy duty (Article 4) has been in force since February 2025 already, but national fines (up to €7.5M or 1% of global turnover for transparency failures) start biting from August. AI-literacy training is itself an eligible SME Packages AI cost.

Potential programme-level refinements. No 2026 changes to rates, ceilings, or eligibility have been announced as of this writing. The programme appears to run on an ongoing-applications basis rather than a capped annual envelope, but the Ministry has signalled it will monitor uptake. If rates or scope change, we will update this page.

MeluXina + national AI strategy operationalisation. Luxembourg's national AI strategy (May 2025) and the LIST-hosted MeluXina supercomputer access route are increasingly being positioned as part of a bundled offer alongside the grants. At time of writing, MeluXina access is a separate application; expect clearer integration guidance later in 2026.

Frequently asked questions

Can I apply for SME Packages AI more than once? Yes. You can run one package, close it, then start another. You cannot stack two AI packages on the same costs simultaneously.

Does the 70% apply to the VAT as well? No. The €3k and €25k bounds are both HT. The grant reimburses 70% of the HT project cost; VAT is entirely your responsibility.

What if my project needs work to begin now and my application is still being reviewed? Wait. Starting before written approval disqualifies the aid retroactively. If you genuinely cannot wait, treat the project as self-funded and forfeit the grant.

Can a foreign company's Luxembourg branch apply? Probably not without its own Luxembourg business permit and RCS registration. The autorisation d'établissement requirement prioritises a distinct Luxembourg legal entity. Your first pre-analysis meeting is the right place to test this.

Is a DPIA mandatory? Mandatory wherever the AI processes personal data. Strongly advised even when it does not, evaluators respond well to an explicit "here is our data-handling approach" paragraph. With EU AI Act Article 4 in force since February 2025, AI-literacy training for affected staff is also expected and is itself eligible for funding.

Can I combine the grant with a bank loan? Yes. Many SMEs use an InvestEU-backed loan (BGL BNP Paribas, ING Luxembourg, BCEE, Spuerkeess) to cover the 30% cost share and the working-capital gap between paying the invoice and receiving the reimbursement.

What does the Ministry actually do during review? They verify SME status and Luxembourg-established status, check de minimis history, evaluate the devis for clarity and proportionality, and confirm the AI use-case is a genuine implementation rather than speculative R&D.

Is there an appeal if I am rejected? Formal appeal procedures for SME Packages AI specifically are not published, but general Luxembourg administrative-law appeal routes apply (administrative tribunal). In practice, a resubmission with the Ministry's feedback incorporated is the more productive route.

How to get started

The first 48 hours of effort are the highest-leverage. If you are seriously considering an AI project in the €3 to €25k HT window:

1. Pull a de minimis history report from your accountant or the Ministry, confirm you have headroom inside the €300k three-year ceiling.
2. Write a one-page project brief describing the business problem, the AI approach, the expected outcome in measurable terms, and a rough cost range.
3. Book the pre-analysis appointment (House of Entrepreneurship for most businesses, eHandwierk for craft trades).
