Beginning in 2011, the IRS was auditing Trump's $72.9 million tax refund covering multiple years of paid taxes; the audit was not resolved as of 2020. If the IRS determines that the refund was improper, Trump would be required to repay more than $100 million, which includes interest on the amount. Trump has also personally guaranteed $421 million in debt, most of which is due within four years. Trump previously expressed regret that he had personally guaranteed debt during the 1980s which brought him close to personal bankruptcy when his businesses faltered in the early 1990s. The bulk of the debt came from Trump's struggling Doral golf resort ($125 million) and the Washington D.C. Trump International Hotel ($160 million). Trump also had failed to pay back $287 million in debt since 2010, according to the Times "far more money than previously known". Forgiven debt is supposed to be treated as income, but Trump used tax provisions to avoid or defer reporting it as such.
