This is a great example of exactly how brainwashed most of you on the left are on this topic... this lie has been repeated enough that you all just take it as fact now, when it's complete bs.
Income data published by the IRS clearly show that on average all income brackets benefited substantially from the Republicans’ tax reform law, with the biggest beneficiaries being working and middle-income filers, not the top 1 percent, as so many Democrats have argued.
A careful analysis of the IRS tax data, one that includes the effects of tax credits and other reforms to the tax code, shows that filers with an adjusted gross income (AGI) of $15,000 to $50,000 enjoyed an average tax cut of 16 percent to 26 percent in 2018, the first year Republicans’ Tax Cuts and Jobs Act went into effect and the most recent year for which data is available.
Filers who earned $50,000 to $100,000 received a tax break of about 15 percent to 17 percent, and those earning $100,000 to $500,000 in adjusted gross income saw their personal income taxes cut by around 11 percent to 13 percent.
By comparison, no income group with an AGI of at least $500,000 received an average tax cut exceeding 9 percent, and the average tax cut for brackets starting at $1 million was less than 6 percent. (For more detailed data, see my table published here.)
That means most middle-income and working-class earners enjoyed a tax cut that was at least double the size of tax cuts received by households earning $1 million or more.
Republicans’ 2017 tax reform law did exactly what was promised: It lowered taxes for all income groups.
