Former Sen. Rick Santorum (Pa.) had tax trouble he needed to sort out on his Pennsylvania home.

The Republican presidential contender had a lien filed against him on his suburban Pittsburgh home after he was late on his 2009 property taxes.
 
Penn Hills Township filed a lien against Santorum for just under $500 last fall for his unpaid 2009 property taxes, the Pittsburgh Post-Gazette reported. He paid the tax bill a few months late, which meant he was slapped with a $40 penalty. His 2010 taxes on the Penn Hills house, which he bought in 1997 for $106,000, were paid on time.

The Santorum family spends most of its time at a larger home in Northern Virginia, but they have maintained their house in Penn Hills next to his in-laws' home. This isn't the first time the former senator has fallen delinquent on the property taxes.

The township filed a $275 lien against him in 2003, and the Penn Hills school district went after him for slightly over $200 in 2001. Santorum paid off both liens within a year, according to the Post-Gazette.

Santorum's residency was an issue in his 2006 reelection bid, which he lost to Sen. Bob Casey Jr. (D-Pa.).

Santorum will announce his presidential bid in Somerset County, southeast of Pittsburgh, on June 6.
