Minerals Resource Rent Tax

The Minerals Resource Rent Tax (MRRT) was a tax on profits generated from the mining of non-renewable resources in Australia. It was a replacement for the proposed Resource Super Profit Tax (RSPT).

The tax, levied on 30% of the "super profits" from the mining of iron ore and coal in Australia, was introduced on 1 July 2012. A company was to pay the tax when its annual profits reach $75 million, a measure designed so as not to burden small business. The original threshold was to be $50 million until independent MP Andrew Wilkie negotiated an amendment. Around 320 companies will potentially be affected by the changes.
