WASHINGTON (Reuters) — President Joe Biden's proposed U.S. government budget would raise tax receipts by $4.951 trillion over 10 years, including more than $2.7 trillion in tax hikes on businesses and nearly $2 trillion on wealthy individuals and estates, the U.S. Treasury said on Monday.
The budget plan also calls for an additional $104.3 billion in mandatory funding for the Internal Revenue Service on top of $80 billion won by the tax agency in 2022, the Treasury said in its «Green Book» estimates of the budget's revenue effects.
