Republicans touting the new tax-cut plan released by the House of Representatives on Nov. 2 insist it will do wonders for the middle class. A lot of people don’t believe it.

In a new Yahoo Finance poll, 31% of respondents felt their taxes would go up under the GOP tax plan, while 42% said their taxes would go down. Twenty-three percent felt they’d end up the same and 5% weren’t sure. (Numbers don’t add to 100 because of rounding.)

Those findings suggest Republicans aren’t convincing people that their tax-cut plan will be good for the middle class, or the economy overall. House Speaker Paul Ryan says a typical family with two kids would save $1,182 in taxes per year under the plan. In our survey, however, 22% of voters in that income bracket — between $50,001 and $75,000 in annual household income — feel their taxes will go up. That’s a big messaging problem for Republicans, including President Donald Trump, who backs the House plan.

The sweeping House plan would revamp both the corporate and individual side of the income-tax code. It would slash the corporate tax rate to 20% from 35%, to make the United States a more attractive place for global companies to do business. On the individual side, it would replace seven income brackets with five and undoubtedly lower the tax burden for some filers. But by shifting deductions around, the House plan makes it difficult for any given family to tell whether they’d end up better off or worse off under the plan, leaving plenty of room for critics to demagogue the whole proposal.

Not surprisingly, people with higher incomes are more likely to believe their taxes will go up. Among people with incomes below $150,000 a year, 23% think their taxes will rise under the GOP plan. Above $150,000, 36% think they’ll face a higher tax bill. In a way, that’s by design. Since the GOP plan would put new limits on the deductibility of mortgage interest and state and local taxes— deductions typically claimed by wealthier filers — it’s likely to hit higher earners harder.

Even some Trump voters feel they’d pay more under the Republican plan. Of poll respondents who voted for Trump, 19% say their taxes will go up. Of those who didn’t vote for Trump, 39% think their taxes will rise. The gap could reflect the large portion of Democrats who presumably did not vote for Trump and live in high-income states such as New York and California.

More than 8,000 people took the poll, which we ran on Nov. 2 and Nov. 3. The full results are here. If there’s good news for Republicans, it’s that voters do think their plan would make taxes easier to navigate. Forty-five percent of respondents said the plan would make their taxes simpler, while just 6% said it would make their taxes more complicated. Thirty-seven percent expect no change and 11% aren’t sure.
