Changes to the tax law might concern some Americans, but that's not the main thing keeping most up at night. Instead, it's the fear of unexpected expenses, according to financial website Lending Tree, which polled more than 1,000 adults on their financial concerns for 2018.
Nearly half, or 43 percent, listed "unexpected expenses" as their primary concern, while 34 percent chose the daily burden of "making ends meet." About a third, 29 percent, said they were most concerned with "health care costs" and 18 percent said the same of "tax changes."
