Selected funding instrument: INTER MOBILITYAmended law of 31 May 1999 establishing a National Research Fund in the public sector, in particular Articles 2 and 3, as well as the following implementing regulations:
- Amended Grand-Ducal regulation of 27 July 2000 laying down the procedures relating to the presentation, selection and implementation of research activities benefiting from a grant from the National Research Fund.
- Amended Grand-Ducal regulation of 6 October 2008 relating to the methods of allocation, calculation, and management of training & research grants.
As part of its legal mission, the National Research Fund (FNR) is called upon to:
- allocate grants to research projects selected based on scientific quality criteria, taking into account their economic, social, or cultural potential;
- allocate grants for training & research, and finance measures linked to their promotion in order to support research trainees;
- contribute to the implementation and use of the research results of these programmes and projects and ensure respect for intellectual property generated by the activities supported;
- award grants to researchers and scientists and allocate subsidies to individuals as well as associations engaged in activities of scientific nature;
- promote, coordinate, or manage, in whole or in part, Luxembourg’s participation in international research cooperation programmes, including the allocation of grants to research projects within the framework of international programmes.
Article 3(3) of the law of 31 May 1999 as amended specifies in particular:
Eligible expenses in this respect include personnel expenses, expenses for third party services, operating and acquisitions expenses, and other expenses relating to the implementation of the research activities concerned, and the use and publication of their results. Acquisition, construction, or property development expenses may be considered eligible expenses if they are deemed indispensable for carrying out this research.
The purpose of this document, hereinafter referred to as the “Regulations” is:
- to specify the different costs categories and expenses eligible for reimbursement by the FNR, in compliance with legal provisions,
- to set the eligibility criteria and the terms under which said costs and expenses are reimbursed for the various funding instruments implemented by the FNR
- and to specify the themes: scope, grant ceilings, co-funding, double ceiling, eligibility according to progress, changes to budget breakdown, monitoring procedures, as well as general references.
If one or more provisions of these Regulations are found to be null, void, or contrary to a law or to a Grand-Ducal regulation, they will be deemed unwritten, but the other provisions will retain their validity in full.
Term | Description |
Agreement | The contract signed between the Parties and the FNR regulating the terms and conditions for allocating a grant or training & research grants |
Beneficiary | Other term used for a Party eligible for FNR funding |
Coordinator | The Party in charge of coordinating the Project where the Agreement is signed with several contractors |
Partner | A natural or legal person with whom the Parties associate in order to carry out the Project but who is not a signatory to the Agreement |
Party | The natural or legal person that signs the Agreement and commits to respect the terms thereof |
Project | The project selected for FNR funding and given a unique identification number in the online submission system |
The Regulations can be used as follows to ascertain the eligible costs for a specific FNR funding instrument:
Stage | What to do? |
1 | The beneficiary should check Annex 3 “eligible budget lines by funding instrument“. This table indicates the different categories of eligible costs per instrument.
|
2 | The beneficiary should then consult 6.1. ( Section 6 ) to 6.8. (direct costs), and Section 7 (indirect costs) to find out the eligibility criteria for the costs in question.
Annexes 3.1 to 3.6 set out the specific regulations as detailed in sub-sections 6 for different categories of costs and by funding instrument. |
Note that sections 1 to 5 and 8 to 12 include other procedures to be considered for FNR funding, as mentioned above under section 1.3.
The Regulations apply to all FNR Beneficiaries, as defined and identified on the FNR website, under the section “FNR Beneficiaries” (https://archive.fnr.lu/fnr-beneficiaries/) and cover all FNR funding instruments ( https://archive.fnr.lu/funding/).
To be eligible for FNR funding, certain categories of beneficiaries must be accredited[1] by the Ministry of Higher Education and Research or the Ministry of the Economy.
To be eligible, expenses must be real, justified, reasonable, necessary, and related to the Project. Granting of FNR funding may not have the purpose or effect of generating a profit for the Beneficiary(ies). Section 11 provides information on monitoring procedures.
The granting of FNR funding may in no case constitute double funding of operating, acquisition or personnel costs already subsidised by the State or financed by the Parties via national or foreign third-party sources of funding other than the FNR.
The Parties are authorised to apply for one or several other aid(s) from other funders for the same Project – or for a similar Project (in full or in part) – for which a grant application has been submitted to the FNR. The Parties must, however, inform the FNR of this when submitting the grant application. Two Projects are deemed of a similar nature if they (in full or in part) describe the same main objectives or constitute a mere adaptation.
Once the FNR grant has been granted and accepted by the Parties, the interdiction of double funding applies.
VAT is not an eligible cost where the Party(ies) can recover VAT from the Luxembourg tax authorities, in accordance with Luxembourg indirect tax regulation.
The FNR reserves the right to set for each funding instrument grant ceilings per Project. For certain funding instruments, the Beneficiaries also have co-funding obligations.
The maximum amounts for “training & research grants” are set by Grand-Ducal regulation.[1]
Annex 1 below includes the various funding instruments indicating the grant ceilings per Project, where applicable, as well as the co-funding terms. This information is included in the launch documents for relevant calls for proposals.

The Agreements detail the duration of the Project as well as the execution, dissemination, and exploitation periods during which different types of costs are eligible.
Annex 2 below details the different stages of progress and specifies the applicability of a dissemination or exploitation period by funding instrument.
For the relevant funding instruments (BRIDGES; CORE; INTER; OPEN and RESCOM) Section 8 details the eligible costs during the dissemination period.

Annex 2: Progress periods – eligible costs

INTER MOBILITY | No | No |
Costs are allocated to direct and/or indirect budget lines as set out in Section 6 and Section 7
In all funding instruments, except for instruments allocating “research & training grants”, a budget table must be submitted using the relevant form alongside the grant application.
All estimated costs for the Project must be detailed and explained, as must the sources and amounts of the various financial contributions (FNR, own funds, funding from third parties other than the FNR) from which the Project is to benefit. Depending on the funding instrument, more detailed explanations may be required. The FNR may decide to limit its funding if no satisfactory justification of the budget is provided.
The budget table must indicate the maximum allowable amounts that can be charged to the FNR for reimbursement for each budget line.
Some costs may be indicated on a verifiable flat-rate basis (for example, in relation to activities performed regularly by the relevant Party), provided that they do not differ substantially from the actual incurred (real) cost and the activities are in accordance with the FNR eligibility criteria.
No reallocation is allowed between direct and indirect costs, as well as for costs listed under 6.8 in Section 6 and the Junior track [CORE Junior only] mentoring costs (see 6.6.5).
Section 10 describes the implementation of a change in the budget breakdown [not applicable to AFR; Industrial Fellowships; IPBG; Open Access Fund; PRIDE; RESCOM]. In case of doubt, the FNR must be contacted.
Definition. Direct costs are expenditures directly and solely attributable to a specific Project and for that project only. They must be supported by an auditable record, comply with the regulations of the Party(ies), and adhere to the present Regulations.
Categories. Budget lines are divided into different categories: (1) personnel costs, (2) equipment, (3) consumables, (4) travel costs, (5) mobility and training allowance, (6) subcontracting, (7) other costs and (8) specific non-transferable costs.
Eligibility. Annex 3 below details the eligibility of budget lines by funding instrument. The costs eligibility criteria are defined below. Note that internal invoicing expenses are eligible provided that these expenses are (i) directly attributable to the Project, are (ii) measurable and valued according to internal regulations in force and (iii) are not contradictory to the eligibility criteria for the various budget lines. Consultancy costs to prepare a funding request are not eligible.
Annex 3: Eligible budget lines by funding instrument
FNR funding instrument | Personnel Costs (6.1) |
Equipment (6.2) |
Consumables (6.3) |
Travel costs (6.4) |
Mobility and training allowance (6.5) |
Subcontracting (6.6) |
Other costs (6.7) |
Specific non-transferable costs (6.8) |
Indirect Costs (6.9) |
---|---|---|---|---|---|---|---|---|---|
INTER MOBILITY | Yes | No | No | Yes | Yes | No | Yes | No | No |
This budget line refers to the personnel allocated to the Project. More specifically, it refers to the payroll costs of all staff, full or part-time, who work directly on the Project and are stated in the Project description, where the working hours spent (monitoring and valuation) can be duly supported by an auditable record.
The concerned staff must have a valid employment contract (or equivalent contract)[1] with the Party/Beneficiary in accordance with the legal and regulatory provisions in force.
The Principal Investigator or Project Manager must be known at the time of application submission. The FNR requirements for Principal Investigator(s), Supervisor(s), and Project Manager(s) (http://bit.ly/PIandSupervision) within FNR funded projects apply.
The need for staff as provided for in the budget must be clearly outlined (name, category of staff: post-doctoral student / PhD student, etc., person already recruited or to be recruited, expected person-months, FNR funding requested).
Changes of profile (e.g. Postdoc to technician) during the execution of the Project must be requested in accordance with the terms as defined in the Agreement.
Actual working time on the relevant Project must be auditable to form the basis of the costs charged to the Project. To do this, the actual working time attributable to the Project must be recorded (time sheets) for each person assigned to the Project.
When persons are contracted to work one hundred per cent (100%) of their time on a single project (whether full-time or part-time), timesheets are not necessary since their costs can only be allocated to that one Project.
In all other cases, timesheets for a given project are mandatory.
There are two categories of personnel costs (6.1.1. & 6.1.2.), with salary costs for “training & research grants” governed by Article 5 of the Grand-Ducal regulation of 6 October 2008 relating to the methods of allocating, calculating, and managing training & research grants, as amended by the Grand-Ducal regulation of 29 October 2014.
[1] The employment relationship must be duly described and justified.
6.1.1. Special rules relating to personnel costs applicable to certain funding instruments
This paragraph lists the specific rules relating to the item “personnel costs” applicable in certain funding instruments.
For grants that fall under “training & research grants”, please refer to the following paragraph (6.1.2).
Personnel costs in relation to international mobility
For a Luxembourg researcher going abroad, the FNR will cover the full salary of the researcher for the whole duration of the visit. The salary costs of university and/or public research centre professors during their sabbatical leave (“congé scientifique”) will not be covered by FNR. However, if the professor or researcher receives only fifty percent (50%) of his or her salary (one (1) year sabbatical leave), the FNR will cover fifty percent (50%) of his or her salary for the entire duration of the Project;
If a researcher based abroad comes to Luxembourg, FNR funding should ensure that the researcher will benefit from a salary which is equivalent to a standard salary of a researcher (with the same track record) employed by the Luxembourg host institution. If the researcher still benefits from a salary from his or her home institution, the FNR funding will be reduced accordingly;
The researcher and the host institution must set up a contractual agreement guaranteeing that all the necessary provisions have been adhered to for the visit. This is applicable to the visiting researcher and to the second visiting researcher, where applicable;
Lump sums
Lump sums for staff categories may be used, provided these are based on real and verifiable figures (implementation of a methodology for calculating unit costs).
“Annex 3.1 table 1 – Special rules relating to personnel costs applicable to certain funding instruments:
FNR funding instrument |
Additional activities (6.1.1.1) |
Cost in relation to international mobility (6.1.1.2) |
Only personnel costs of eligible external parties (6.1.1.3) |
Grouping personnel costs if less than 3 person-months (6.1.1.4) |
Use lump sums (methodology to calculate unit costs) (6.1.1.5) |
PhD personnel costs (6.1.1.6) |
Limitation of personnel assigned to "Junior track" project (6.1.1.7) |
---|---|---|---|---|---|---|---|
INTER MOBILITY | No | Yes | No | No | Yes | No | No |
This budget line covers travel expenses, accommodation and subsistence expenses or allowances, as well as expenses relating to participation in conferences and training.
The relevant section of the budget table, if applicable, can be used to detail these costs when submitting the Project, for example:
- Brief indication of the conferences or technology fairs in which you wish to participate and the number of employees concerned;
- Accommodation and travel expenses for speakers, panellists, and organisers from abroad (for an international conference held in Luxembourg);
- Travel, hotel and meal expenses for guest speakers, moderators, and presenters (promotion of scientific culture);
- Travel costs, entrance fees, guide fees, accommodation, and meals (only for school activities abroad) (promotion of scientific culture);
To reduce the amount of red tape when submitting the Project and to give the team (including PhDs) the necessary flexibility, a lump sum may be indicated. The FNR will only cover the actual incurred travel costs in the final settlement.
Annex 3.3 below specifies the application of specific rules for the various funding instruments where the “travel expenses” item is eligible. These specific rules are as below.
It is therefore essential to provide the total person-months effort of all the people working on the Project. If the Project team requires a higher travel budget, this must be duly justified.
The FNR expects all researchers participating in the Project (in particular PhD candidates) to benefit from this budgetary item provided by the FNR.
Other provisions that apply depending on the funding instrument include the following.
In the case of mobility, the FNR will cover the actual incurred (real) travel costs of the researcher and his or her family (if justified) between the place of usual residence and the host institution. In this context, the FNR retains the definition of the term “family” as all persons linked to the researcher, benefiting from a FNR funding, by (i) marriage or (ii) a recognised relationship having a status equivalent to legal marriage[1] as well as (iii) the researcher’s dependent children. The FNR covers at least one round trip for the researcher, with two reference amounts depending on the family situation of the researcher:
- 1 round trip per cumulated stay of 3 months for the researcher;
- 1 round trip per cumulated stay of 6 months, per family member, if applicable.
Additional travel, for example participation in conferences, etc. is not eligible under this funding instrument.
[1] Equivalence to marriage may depend on the legal provisions of the country of the Institution or on the law of the researcher’s nationality
Annex 3.3. Special rules – travel costs:
FNR funding instrument | Indication of a lump sum (6.4.1) |
Allocation of a maximum of 1 k€ per year and per 12 person*months (6.4.2) |
Scientific school trips (max 250 € per participant) (6.4.3) |
Supplement "Junior track" (6.4.4) |
Mobility - real costs for researcher and family (6.4.5) |
Associated costs for "Advisory Board" and/or "Steering Committee" (6.4.6) |
Associated costs for "Scientific Advisory Board" (6.4.7) |
---|---|---|---|---|---|---|---|
INTER MOBILITY | No | No | No | No | Yes | No | No |
This budget line corresponds to a lump sum allowance granted by the FNR. This line is separate from line “6.4 Travel expenses”.
Annex 3.4 below details the eligibility of the mobility and training allowance for each funding instrument, as well as the application of certain specific rules, outlined below.
Note that this is the maximum amount that can be allocated and that the actual incurred (real) costs will be covered by the FNR in the final settlement. However, sections 6.5.1. and 6.5.4. include single lump sums.
A mobility accommodation allowance
A mobility accommodation allowance. The FNR provides an allowance to cover accommodation costs for the researcher and his or her family[1]. Only two (2) reference amounts, depending on the researcher’s family situation at the start of the Project, are funded by the FNR:
The following reference amounts, depending on the researcher’s family situation at the start of the Project, are funded by the FNR:
- €1500/month: researcher with dependent family,
- €1500/month: researcher without dependent family and a mobility of 6 (cumulative) months or more,
- €1000/month: researcher without dependent family and a mobility of less than 6 (cumulative) months.
If the accommodation allowance is largely insufficient to cover living expenses for a Luxembourg researcher travelling abroad, he or she may request additional funding.
Subject to justification, the FNR may decide on additional funding over and above the allowances stated under in this section.
[1] See section 6.4.5 for a definition of the term “family”
Annex 3.4 Special rules – mobility and training allowance:
FNR funding instrument | One-off travel lump sum (6.5.1) |
A mobility allowance researcher / family (6.5.2) |
Training and mobility allowance (6 k€ or 4 k€) (6.5.3) |
Supplement of 500 € per research trainee (6.5.4) |
