What footnotes do I need to tag?
You need to tag any number in a footnote or a Note if it is in the declared currency (i.e. the currency you report in). This requirement is detailed in Annex 2 (page 6) of the RTS on ESEF. Please be aware that a footnote is not a synonym of the term Notes, which are the Notes to the Primary Financial Statements. Please contact your auditors if you are uncertain about whether or not to tag a number.
This screenshot from section 1.8 (page 18) of the ESMA ESEF Reporting Manual shows an example of the numbers, including numbers disclosed in the footnotes, that must be tagged in a consolidated statement of cash flows (highlighted in yellow):
