The details of the tax filings complicate Trump’s description of himself as a shrewd and patriotic businessman, revealing instead a series of financial losses and income from abroad that could come into conflict with his responsibilities as president. His financial disclosures indicated he earned at least $434.9 million in 2018, but the tax filings reported a $47.4 million loss, AP wrote.

The tax filings also illustrate how a reputed billionaire could pay little to nothing in taxes, while someone in the middle class could pay substantially more than him. Roughly half of Americans pay no income taxes, primarily because of how low their incomes are. But Internal Revenue Service figures indicate that the average tax filer paid roughly $12,200 in 2017, about 16 times more than what the president paid.

The disclosure, which the Times said comes from tax return data it obtained extending over two decades, comes at a pivotal moment ahead of the first presidential debate Tuesday and weeks before a divisive election against Democrat Joe Biden.

Speaking at a news conference Sunday at the White House, Trump dismissed the report as “fake news” and maintained he has paid taxes, though he gave no specifics. He also vowed that information about his taxes “will all be revealed,” but he offered no timeline for the disclosure and made similar promises during the 2016 campaign on which he never followed through.

In fact, the president has fielded court challenges against those seeking access to his returns, including the US House, which is suing to get Trump’s tax returns as part of congressional oversight.

Trump found multiple ways to reduce his tax bills. He has taken tax deductions on personal expenses such as housing, aircraft and $70,000 to style his hair while he filmed “The Apprentice.” Losses in the property businesses solely owned and managed by Trump appear to have offset income from his stake in “The Apprentice” and other entities with multiple owners.

During the first two years of his presidency, Trump relied on business tax credits to reduce his tax obligations. The Times said $9.7 million worth of business investment credits that were submitted after Trump requested an extension to file his taxes allowed him to offset his obligations and pay just $750 each in 2016 and 2017.

The Times said a ruling against Trump could cost him $100 million or more.

The president could also face mounting financial pressure in the years ahead.

During his first general election debate against Democrat Hillary Clinton in 2016, Clinton said that perhaps Trump wasn’t releasing his tax returns because he had paid nothing in federal taxes.

Trump interrupted her to say, “That makes me smart.”
