Republican presidential nominee Donald Trump admitted taking advantage of loopholes in the taxation law to avoid paying federal income taxes for several years.

During Trump’s second presidential debate against Hillary Clinton Sunday, the real estate mogul confirmed that he declared a US$916 million (AU$1.2 billion) loss in 1995, which offset his federal income tax liabilities by way of tax deductions.

“Of course, I do. Of course, I do,” Trump said in response to Anderson Cooper when the debate moderator asked if he had used the loss to erase his tax liabilities.

“I absolutely used it. And so do all of her donors,” he later fired back, referring to Clinton’s business supporters.

Trump has long promised to release his tax returns for public scrutiny until the New York Times reported on his 1995 tax records, wherein he a massive loss that could have allowed him to legally paying federal income taxes for up to 18 years.

The 70-year-old businessman did not offer details how long he was able to avoid paying federal income taxes, but he claimed that, “I understand the tax code better than anybody that’s ever run for president.”
