Mostly True
South Korea's excess tax revenue for this year has reached a record high of more than 50 trillion won, an unprecedented level driven largely by strong corporate tax collections.
The record excess collections stem primarily from corporate tax revenue that came in far above government projections, with semiconductor-sector profits among the key contributors. The scale of the overshoot — described as '50 trillion won + α' to indicate the total exceeds 50 trillion won by an additional, not fully fixed margin — is the largest since such comparisons have been tracked.
The exact size of the 'α' component remains unconfirmed, as year-end settlement figures had not been finalized when the figure was circulated. Government revenue estimates for the year had assumed lower corporate tax receipts, and the gap between projections and actual collections accounts for the bulk of the excess.
The claim that this year's excess tax revenue of '50 trillion won + α' is the largest on record is Mostly True.
