A subsidiary of Allied Farmers has been served with a liquidation notice from Inland Revenue for $4.2 million.
Allied Farmers Rural has been in discussions with the tax department since February 25 when it received a demand notice for $3.7 million in outstanding debt.
A statement from the company, which acquired the assets of Hanover in 2009, said the liquidation notice had been filed on May 1 but it had not been advised of it.
"Allied Farmers Rural will be seeking legal advice to clarify the matter, but in the meantime continues its discussions with IRD."
The company said it remained hopeful of achieving a settlement with the Inland Revenue before the hearing on July 23.
