Robert De Niro Tax Lien - Veteran actor Robert De Niro was compelled to sign a check for over $6.4 million to the IRS on Thursday, reportedly only hours after he found out that he owed the hefty sum.

According to The Smoking Gun, the IRS revealed that the tax lien was lodged with the actor about 3 months ago. But De Niro's spokesman Stan Rosenfield has revealed that the tax bill was sent to the wrong address. "If they sent the bill to the right address, it would have gotten paid sooner," he explains.

Apparently the IRS has one of De Niro's properties in Tribeca incorrectly listed as his residence and had been threatening to go after the property if the actor failed to pay up the debt. De Niro's $6.4 million tax lien is reportedly in relation to his personal 1040 filings in 2013.

Reports indicate that De Niro found out about his outstanding tax debt from the press. It is unclear why no one checked the mails in his Tribeca condominium and informed him of the $6.4 million debt.

Rosenfield said De Niro had a check with the full amount and had it delivered to the offices of the IRS on Thursday.

De Niro and his wife Grace Hightower are currently staying at a plush Central Park West apartment. The 71-year-old actor's home in the same neighborhood caught fire in 2012 and has been under renovation. It is unclear when the works on the property will be completed.

In January, De Niro bought a plush $2.8 milllion West Villa penthouse for his daughter Drena De Niro.

Meanwhile, last year, The Godfather actor finally settled a 7-year-long court case with the City of Gardiner, Montana, over the alleged overvaluation of his $6 million property in the city. He even agreed to settle the legal bills that the town had incurred while fighting him in court.
