The public may not like the idea of tax cuts for the rich, but it can be sold as a plan to lower rates across the board and create a more simple and flatter tax code, according to new polling commissioned by a GOP-aligned group.

A majority of Americans, including nearly half of Democrats, believe that taxes are too high, according to the new national poll conducted by the GS Strategy Group for the advocacy group the American Action Network. The group plans to spend as much as $20 million to promote the Republican tax reform plan.

The poll also asked voters whether they would prefer a simpler, flatter, and "fairer" income tax system for all Americans, or a more progressive system that raises more money from the wealthy. More than 60 percent of respondents opted for simpler.

The tax reform plan that President Trump and congressional Republicans are working toward would likely yield significant tax cuts for high-income earners.

Polling on taxes usually yields different and conflicting answers depending on questions are phrased, making Republicans' bet on tax reform a politically uncertain one.

A problem facing Republicans is that one of the few consistent results in polling is that many voters want to see rich people and bigger corporations pay more.

Yet the poll released Tuesday shows that people are also open to a pitch for tax reform based on simplicity and equal treatment, and lowering taxes across the board.

Republicans have touted the idea of simplifying the tax code, allowing most taxpayers to file on a postcard-sized return, and reforming the IRS.

The poll included 1,000 likely voters and was conducted in early August.
