The King of Pop may be gone but his estate is still being hounded by the IRS. According to Forbes, they are going for more blood:

In a previously unreported court filing, the government says that IRS auditors originally thought the King of Pop owned only 50% of certain master recordings at his death in June 2009, when he really owned 100% of them. That 100% interest was worth $91 million by the IRS’ figuring, compared to the $11 million reported on the Jackson estate tax return.

The change brings the IRS’ valuation of Jackson’s estate and lifetime taxable gifts up to $1.178 billion, compared to the $7 million the estate reported. The IRS now wants a total of $525.6 million in tax and $205.1 million in gross valuation misstatement and negligence penalties. (Any interest owed will be on top of that.) Of course both the IRS and the estate’s values are best regarded as opening bids in what could be a long negotiation. A trial, if there is one, is far off.
