Checks, audits, reviews & investigations

As a beneficiary of H2020 funding, you must keep supporting documents that may be required for:

As a beneficiary of FP7 funding, please see the FP7 audits and certifications guidance on the FP7 Reference Documents page.

Certificate on Financial Statements (CFS)

The CFS is a factual report produced by an independent auditor or Public Officer. Its purpose is to enable the European Commission or grant awarding agency to check whether costs declared in the financial statements are eligible.

A separate CFS must be submitted for each beneficiary (and linked third party) that requests total of EUR 325 000 or more as reimbursement of actual costs and unit costs calculated according to its usual cost accounting practices.

Submitting the CFS

The project coordinator must send the CFSs to the Commission or grant-awarding agency, with the final report, within 60 days of the end of the last reporting period.

For more details, see the Grant Agreement (Article 20.4) for multi-beneficiary grants or mono-beneficiary grants.

Content and format

The CFS should be based on the model in Annex 5 to the Grant Agreement and consist of:

  • the terms of reference, signed by the beneficiary/linked third party and the auditor/Public Officer.
  • the auditor's independent report of factual findings. This report must be issued on the auditor's or Public Officer's letterhead, dated, stamped and signed by the auditor/Public Officer.

Representation letter

According to Article 1.2 of Annex 5 the Beneficiary/Linked Third Party is, amongst others, responsible for the completeness and accuracy of the information provided to enable the Auditor to carry out the Procedures and must provide the Auditor with a written representation letter supporting his statements. You may use this example for the letter of representation related to the CFS.


For any questions about the CFS, you may contact the Horizon 2020 Helpdesk.

Checks, reviews & investigations

    The Commission will - during the implementation of the action or afterwards -
  • check the proper implementation of the action and compliance with the obligations under the grant agreement, including assessing deliverables and reports.
  • carry out reviews on the proper implementation of the action (including assessment of deliverables and reports), compliance with the obligations under the grant agreement and continued scientific or technological relevance of the action.
  • carry out audits on the proper implementation of the action and compliance with the obligations under the grant agreement.


The European Commission may order an audit of your H2020 grant during the project or at any time up to 2 years after the final payment. Any claimed ineligible costs will be recovered or deducted from the next payment.

If there are any systematic errors, the Commission may extend the findings of the audit results to non-audited grant agreements or non-audited periods. Besides these corrections, other measures may be taken, including penalties.

If you have submitted a CoMUC, the auditor will ensure that you have applied the approved methodology consistently.

To learn more about checks, reviews, audit & investigations, please read Article 22 of the H2020 Annotated Model Grant Agreement.
