The New York state tax department has said it is investigating reports that President Donald Trump helped his parents dodge millions of dollars in taxes and received far more money from his father's real estate empire than he has claimed in the past.
The New York Times said its own exhaustive probe of a vast trove of tax returns and confidential records showed Mr Trump had engaged in suspect tax tactics, including "outright fraud" that greatly inflated the funds he received from his parents.
The White House has dismissed the allegations as "misleading".
Mr Trump has stated on numerous occasions that he received little help from his father, New York property developer Fred Trump, in building his fortune.
"The Tax Department is reviewing the allegations in the NYT article and is vigorously pursuing all appropriate avenues of investigation," according to New York state Taxation and Financing spokesman James Gazzale.
The New York Times said Mr Trump received the equivalent of $413 million in today's dollars from his father's real estate activities - having earned $200,000 a year in today's dollars by age three.
By the time he was eight, he was already a millionaire.
Mr Trump was receiving the equivalent of $1 million a year from his father shortly after his college graduation, it added, noting that the funds grew to more than $5 million per year when he was in his 40s and 50s.
The newspaper said the bulk of the funds owed to tax evasion tactics that Mr Trump helped devise, including a "sham corporation" he and his siblings created to hide millions of dollars in gifts from their parents.
There were also millions of dollars in improper tax deductions and Mr Trump helped further reduce his parents' tax bill by undervaluing their real estate holdings by hundreds of millions of dollars on tax returns, according to the NYT.
The newspaper said Mr Trump's parents, Fred and Mary Trump, who died in 1999 and 2000 respectively, transferred more than $1 billion in wealth to their five children.
This could have produced a tax bill of at least $550 million but the Trumps paid a total of just $52.2 million, the NYT said, citing tax records.
