Tax documents published by a committee in the US Congress showed that former President Donald Trump did not pay income tax in the last year of his presidency, as he reported losses in his vast business empire.

The documents, released by the Democratic-led House Ways and Means Committee on Tuesday after a years-long battle, show Trump's income and tax obligations have fluctuated dramatically during his four years in the White House.

According to tax records, Trump paid $1.1 million in federal taxes over two of his four years as president, according to a report reviewed by lawmakers on Wednesday.

The former Republican president paid $ 750 in 2017 and $ 1 million in 2018 and 2019, and nothing in 2020, in which his profits were estimated at about $ 5 billion, and he lost the presidential election in the face of Democrat Joe Biden.

The committee obtained the records after a years-long battle, and voted on Tuesday to approve their publication. This decision is the second blow this week to Trump, who recently announced that he will run again for the presidency in 2024.

A Trump spokesman said the release of the documents was politically motivated.
