S481 final claim — engaging an external accountancy firm

Last verified 27 May 2026


The S481 / S487A final claim is prepared and filed by an external chartered accountancy firm, engaged by the producer specifically for the work. This is not an audit — it is service work. The firm is preparing the Cost of Production accounts and filing the claim with Revenue, on the producer's behalf.

Why "not an audit"

An audit is an independent attestation — an auditor opines on accounts prepared by management. The S481 final-claim work is the opposite: the firm is doing the preparation itself. There is no opinion, no fieldwork in the audit sense, no qualified-vs-unqualified outcome. The firm delivers Cost of Production accounts and a filed claim.

Common Irish practice: confusing the two is widespread, and producers sometimes describe the firm as "our auditor". Strictly speaking they are the producer's accountant for the S481 final claim — and the engagement letter flows from firm to producer (the firm accepts the brief).

Producer obligation

Engage the firm before the production wraps. Trying to find a S481 specialist after wrap typically means a long queue — these firms are seasonal and book up during the year.
