Top Energy is opposing an Inland Revenue plan to tax the rebate it pays its customers every year.
The proposal came to light last week via a 'top secret' IRD memo revealing that the department was planning to impose a tax of 28 per cent, on the basis that the rebate (traditionally $200 per residential Top Energy customer) is effectively a dividend.
If enacted, the change will affect 12 community trust-owned lines companies, including Top Energy and North Power.
Top Energy chief executive Russell Shaw said his company would be submitting against the proposal and explaining the rationale behind the credit, which he described as a discount (paid this year as a credit on the November power bill).
Lines companies had long had a "binding ruling" from the IRD that the discount would not be taxed, but that agreement had expired in 2010.
