That is completely false.
A single taxpayer gets a standard deduction plus a personal exemption worth $10,350.
In other words, you pay zero income tax on your first $10,350 of income.
Also, a single person who earns less than $15,000 total is eligible for the Earned Income Credit, and is also eligible for Medicaid in most states (via ObamaCare), or, if over 65 and eligible for Medicare, you pay no Part B monthly premium, no co-pays, and no Medicare deductibles.
Also, most elderly people pay no income tax on their Social Security pension.
Also, people over age 65 get almost $12,000 in standard deductions and personal exemptions, $1,600 more than younger people.
50% of the people in this country pay no income tax....some actually get a return even though they paid nothing!!!! Talk of low income workers getting taxed is ludicrous....one cannot get a tax cut if one pays no taxes!!!
