Crown Perth is raking in the big bucks this year, in the wake of a big boost in revenue and tax cuts given to the company by the WA government.

On Christmas Eve, the international commission business tax was cut by 3%, from 11-8%. This means that WA's coffers will not be reaping the full benefits of the Crown Perth's gaming business' healthy financial year, which happened to be augmented by International high rollers spending big money at Crown Perth and Australian online casinos.

The company's annual report shows that their international VIP revenue in Perth grew by almost 50% in the last fiscal year, from $173 million to $249 million. But, that's not all, total gaming revenue increased by over 10% to $747 million.

Despite the huge revenue growth, it is estimated that Crown only paid the government a little over $100 million in casino tax in the 2014-15 fiscal year, this is per information received from the Department of Racing, Gaming, and Liquor.

It's also important to note that the department also said that this number doesn't include reimbursements made to the gaming business because of the tax cuts. Even without these reimbursements, Crown only paid the government an extra $2 million this year in casino tax, when compared to the year before, this is based in information from the annual reports of the Gaming and Waging Commission of Western Australia.

In a surprise move, former gaming minister Terry Waldron announced the tax cut before he stepped down from Cabinet last year. This was done in an effort to make Crown more competitive in the future. If the company isn't able to maintain a certain level of success, it may hurt both Crown and the government in the long run.

Waldron's ruling was predicated by years of lobbying by executives at Crown. In fact, the company made it a point to meet with a number of Barnett Government ministers, like Treasurers Mike Nahan and Troy Buswell, way back in 2011. The first formal request to Waldron was made in April of 2012.

About a year later, Crown flew Barry Sargeant, the director-general of the Department of Racing, Gaming, and Liquor to Macau, where the company has many casino investments. In a written statement that he wrote last year, Waldron defend the trip stating that he went away to get a better understanding of the international VIP business in Macau and its implications for operations in the local area.

Under the arrangement between the WA Government and Crown, the company must pay at least $9.05 million in international commission business tax each year for the next five years.
