If any of your clients need valuation-related work because of the new tax law, don’t wait for them to call you. Over a quarter (26%) of Americans don’t even know there was a tax bill in the first place, according to a recent survey. What’s more, of those who do know there is a new tax law, they don’t know much about it. NerdWallet, a personal financial planning site, did the survey, polling 2,000 U.S. adults on legal and illegal tax-saving strategies, tax bracket knowledge, concerns about filing taxes incorrectly, and understanding the new tax bill.
