Over the past two weeks, The New York Times has been publishing the results of an examination of decades of personal and corporate tax records for President Trump and his businesses in the United States and abroad. The records stretch from his days as a high-profile New York real estate investor through the beginning of his time in the White House.

A team of Times reporters has pored over this information to assemble the most comprehensive picture of the president’s finances and business dealings to date, and we will continue our reporting and publish additional articles about our findings. We are not making the records themselves public because we do not want to jeopardize our sources, who have taken enormous personal risks to help inform the public.

We are publishing this series of reports because we believe citizens should understand as much as possible about their leaders and representatives — their priorities, their experiences and also their finances. Every president since the mid-1970s has made his tax information public. The tradition ensures that an official with the power to shake markets and change policy does not seek to benefit financially from his actions.

Mr. Trump, one of the wealthiest presidents in the nation’s history, has broken with that practice. As a candidate and as president, Mr. Trump has said he wanted to make his tax returns public, but he has never done so. In fact, he has fought relentlessly to hide them from public view and has falsely asserted that he could not release them because he was being audited by the Internal Revenue Service. More recently, Mr. Trump and the Justice Department have fought subpoenas from congressional and New York State investigators seeking his taxes and other financial records.

Our latest findings build on our previous reporting about the president’s finances. The records show a significant gap between what Mr. Trump has said to the public and what he has disclosed to federal tax authorities over many years. They also underscore why citizens would want to know about their president’s finances: Mr. Trump’s businesses appear to have benefited from his position, and his far-flung holdings have created potential conflicts between his own financial interests and the nation’s diplomatic interests.

The reporters who examined these records have been covering the president’s finances and taxes for almost four years. Their work on this and other projects was guided by Paul Fishleder, a senior investigative editor, and Matthew Purdy, a deputy managing editor who oversees investigations and special projects at The Times.

Some will raise questions about publishing the president’s personal tax information. But the Supreme Court has repeatedly ruled that the First Amendment allows the press to publish newsworthy information that was legally obtained by reporters even when those in power fight to keep it hidden. That powerful principle of the First Amendment applies here.
