Tax Appeals Commission

The Tax Appeals Commission hears appeals in tax matters, including stamp duties and duties of customs and excise. The Finance (Tax Appeals) Act 2015 revises the law on those appeals and establishes An Coimisiún um Achomhairc Chánach, or in English the Tax Appeals Commission, and defines its functions.

The establishment day appointed by the Finance (Tax Appeals) Act 2015 (Establishment Day) Order 2016 (S.I. No. 111/2016) is 21 March 2016.

How to read these figures

These are reported values from published purchase order and payment records — not verified cash paid, and not total spending by this organisation. A row may be a purchase order, a payment, or another reported transaction; the source files often do not say which.

Coverage and quality vary. Some fields are blank, supplier names are free text (the same firm can appear under many labels), and descriptions are inconsistent rather than a controlled taxonomy. An amount alone says nothing about value for money and it may or may not include VAT.

Records are retrieved from each organisation’s published files such as spreadsheets, PDFs, and other formats of uneven quality. Extraction techniques (including automated parsing) can introduce gaps, misreads, or incomplete rows when source layout or quality is poor. Treat the data as a starting point for investigation, not a definitive ledger.
