Tips for carbon taxed builders

MASTER Builders fears the Federal Government's carbon tax will have far-reaching consequences for businesses, consumers and the Australian economy.

Master Builders director of housing policy Paul Bidwell said there was no doubt consumers would be impacted by the tax when it comes into effect on July 1.

"The carbon tax will increase the cost of many goods and services including electricity and many building materials, so you will need to factor these additional costs into building jobs that will run past or start after July 1," he said.

"While the cost impact will vary depending on the materials used, the size of the building and the location; a number of economic consultants have modelled the price impact of the carbon tax on the cost of a new home.

"For example, The Allen Consulting Group has released a report that estimates that the carbon tax will add around $3821 to its model two-storey brick veneer 200m2 house.

"However, this cost increase is just an estimate and the best way to assess the cost impact of the carbon tax on a business will be to speak to associated suppliers about their post July 1 prices.

"Although it is quite likely that the price of bricks, concrete, glass and aluminium will rise as a result of the carbon tax, builders and trade contractors should never inform clients that they are putting their prices up to cover carbon tax, unless they are absolutely certain of the exact costs involved.

"For building contractors, ensuring you pass on the additional costs associated with a particular building job to a client simply makes good business sense.

"However, in the current situation, this can be a challenging task, particularly given many suppliers, manufacturers and distributors are not yet sure about how the carbon tax will affect their prices.

Master Builders has developed some 'dos' and 'don'ts' for building contractors when dealing with the carbon tax.


  • Increase your contract price from 1 July 2012 if you are very confident in your estimates.
  • Avoid ACCC penalties for deceptive and misleading behaviour and price gouging - unless you are absolutely sure, don't tell a client that your prices will increase, for example, by 10% or 20%.
  • Take the safe approach and tell your client that your prices will rise at the start of the new financial year and leave it at that.


  • Advise your client that the price rise is due to the carbon tax if you only have a rough estimate of the cost impact.
  • Tell clients that your prices have risen solely because of the carbon tax when in fact they have risen because of a range of factors.
  • Increase your price and tell the customer it is to cover the carbon tax. If you cannot fully substantiate your statement, you will likely break the law and the ACCC may prosecute you. If you are found guilty, the penalties are very substantial.
