From what I've read. Half of that 47% are people who aren't required to pay taxes because their income is too low or the receive certain benefits.
About half are supposably low income. So a family of four that made less than about 26,000$ gets enough tax credits that essentially they aren't paying taxes. However those people still pay taxes in form of state taxes, payroll taxes and sales tax.
The other half is elderly persons who have non-taxed social security income and also some other old person tax benefits.
What I read said less than 1% of people who don't pay tax are outside of these two groups.
Also many of the states with the highest concentrations of non-payers are red states, though it is true that very low income households tend to support the democrats.
Infants, housewives, soldiers, retirees, the disabled, students, the millionaires, the billionaires, the poor, the unemployed, etc.
There is your 47% who pay no federal income tax
This is an excellent list. I would also add the elderly, corporations that received bailouts during the financial crisis and afterwards, investors, Wall Street firms that received tax breaks, and farmers.
