I heard that Biden had a secret bank account in China and actually paid more in income taxes in China than he did in the US
Also, despite an internal policy that mandates the review of presidential finances, the IRS failed to audit President Biden during the first two years of his presidency.
You heard wrong. It was Trump who wasn't audited the first two years.
WASHINGTON—The Internal Revenue Service has completed two audits of President Biden's tax returns since he took office in 2021, but records released this week show it has not finished any audits of Donald Trump from his time in the White House.
For tax year 2020, the IRS determined that Mr. Biden and his wife, Jill, were owed an additional refund, White House spokesman Andrew Bates said. For 2021, which the Bidens filed in April 2022, the couple paid an extra $13 after the audit.
