Numerous farmers have reported receiving the letters this Monday, with tax bills ranging from €5,000 to €50,000. The Irish Farmers Journal understands that farmers are encouraged to pay and file the corresponding tax within weeks to minimise penalties.In a statement to the Irish Farmers Journal, a spokesperson for the Revenue Commissioners said: “Certain milk suppliers received patronage or free shares in proportion to the quantity of milk supplied to a co-op. Such shares should be included as trading income subject to income tax, USC and PRSI based on their market value when received. Revenue has written to a number of such shareholders advising them of the possible tax liability in relation to the value of free shares received, and giving an opportunity to come forward now and pay any income tax due in this matter.”
