And no surprise, it doesn’t look good for Trump…

The Times obtained Donald Trump’s tax information extending over more than two decades, revealing struggling properties, vast write-offs, an audit battle and hundreds of millions in debt coming due.

Donald J. Trump paid $750 in federal income taxes the year he won the presidency. In his first year in the White House, he paid another $750.

He had paid no income taxes at all in 10 of the previous 15 years — largely because he reported losing much more money than he made.

As the president wages a re-election campaign that polls say he is in danger of losing, his finances are under stress, beset by losses and hundreds of millions of dollars in debt coming due that he has personally guaranteed. Also hanging over him is a decade-long audit battle with the Internal Revenue Service over the legitimacy of a $72.9 million tax refund that he claimed, and received, after declaring huge losses. An adverse ruling could cost him more than $100 million.

The tax returns that Mr. Trump has long fought to keep private tell a story fundamentally different from the one he has sold to the American public. His reports to the I.R.S. portray a businessman who takes in hundreds of millions of dollars a year yet racks up chronic losses that he aggressively employs to avoid paying taxes. Now, with his financial challenges mounting, the records show that he depends more and more on making money from businesses that put him in potential and often direct conflict of interest with his job as president.

The New York Times has obtained tax-return data extending over more than two decades for Mr. Trump and the hundreds of companies that make up his business organization, including detailed information from his first two years in office. It does not include his personal returns for 2018 or 2019. This article offers an overview of The Times’s findings; additional articles will be published in the coming weeks.

Examining the Trump Organization’s tax records, a curious pattern emerges: Between 2010 and 2018, Mr. Trump wrote off some $26 million in unexplained “consulting fees” as a business expense across nearly all of his projects.

In most cases the fees were roughly one-fifth of his income: In Azerbaijan, Mr. Trump collected $5 million on a hotel deal and reported $1.1 million in consulting fees, while in Dubai it was $3 million with a $630,000 fee, and so on.

Mysterious big payments in business deals can raise red flags, particularly in places where bribes or kickbacks to middlemen are routine. But there is no evidence that Mr. Trump, who mostly licenses his name to other people’s projects and is not involved in securing government approvals, has engaged in such practices.

Rather, there appears to be a closer-to-home explanation for at least some of the fees: Mr. Trump reduced his taxable income by treating a family member as a consultant, and then deducting the fee as a cost of doing business.

The “consultants” are not identified in the tax records. But evidence of this arrangement was gleaned by comparing the confidential tax records to the financial disclosures Ivanka Trump filed when she joined the White House staff in 2017. Ms. Trump reported receiving payments from a consulting company she co-owned, totaling $747,622, that exactly matched consulting fees claimed as tax deductions by the Trump Organization for hotel projects in Vancouver and Hawaii.

When Mr. Trump glided down a gilded Trump Tower escalator to kick off his presidential campaign in June 2015, his finances needed a jolt.

His core businesses were reporting mounting losses — more than $100 million over the previous two years. The river of celebrity-driven income that had long buoyed them was running dry.

If Mr. Trump hoped his unlikely candidacy might, at least, revitalize his brand, his barrage of derogatory remarks about immigrants quickly cost him two of his biggest and easiest sources of cash — licensing deals with clothing and mattress manufacturers that had netted him more than $30 million. NBC, his partner in Miss Universe — source of nearly $20 million in profits — announced that it would no longer broadcast the pageant; he sold it soon after.

Now his tax records make clear that he is facing a battery of threats to his business and his own financial well-being.

Over the past decade, he appears to have filled the cash-flow gaps with a series of one-shots that may not be available again.

In 2012, he took out a $100 million mortgage on the commercial space in Trump Tower. He took nearly the entire amount as a payout, his tax records show. His company has paid more than $15 million in interest on the loan, but nothing on the principal. The full $100 million comes due in 2022.

In 2013, he withdrew $95.8 million from his Vornado partnership account.

And in January 2014, he sold $98 million in stocks and bonds, his biggest single month of sales in at least the last two decades. He sold $54 million more in stocks and bonds in 2015, and $68.2 million in 2016. His financial disclosure released in July showed that he had as little as $873,000 in securities left to sell.

Mr. Trump’s businesses reported cash on hand of $34.7 million in 2018, down 40 percent from five years earlier.

What’s more, the tax records show that Mr. Trump has once again done what he says he regrets, looking back on his early 1990s meltdown: personally guaranteed hundreds of millions of dollars in loans, a decision that led his lenders to threaten to force him into personal bankruptcy.

This time around, he is personally responsible for loans and other debts totaling $421 million, with most of it coming due within four years. Should he win re-election, his lenders could be placed in the unprecedented position of weighing whether to foreclose on a sitting president.
