After surveying more than 2,000 U.S. adults on the new tax bill, legal and illegal tax-saving strategies and tax bracket knowledge, personal finance site NerdWallet found that most Americans are in the dark.
An increasing share of Americans don't know their income tax bracket: 48 percent, compared to 40 percent in 2016. And 1 in 14 Americans don't even know what a tax bracket is.
To further complicate things, the tax brackets are changing under the the new GOP tax plan.
"About 1 in 4 Americans (26 percent) don't know that a new tax bill was signed into law in 2017," NerdWallet reports, "and about half (51 percent) don't know that income tax brackets are changing under the new rules."
