CANBERRA, Australia—Wealthy Australian art collectors are coming under scrutiny by the country's tax office amid concerns that they are gaining inappropriate benefits with the help of museums, reports the Australian.

The newspaper refers to a report from the Australian Taxation Office that identifies nine "potential areas of mischief," including claiming to donate a work they haven't, officially transferring works but keeping possession of them, and inflating values of works to reach tax-deductible requirements.

The report admits that it is not known how much the practices are happening, but says "the likelihood of these concessions being applied for the private benefit of associates cannot be dismissed."

It recommends a risk-assessment program designed to analyze the dealings of museums linked to wealthy individuals.
