    This gets proposed as a way to implement basic income (UBI). It is only equivalent when the lowest tax bracket is equal to the NIT.

    ex: if NIT of 25% up to $40k, and 25% income tax rate up to $50k, then at $40k income, you would pay 0 net income tax. At 0 income, you would receive $10k, and at $50k income, you’d pay $2500. Every $10k of income results in $2500 extra taxes or less of a refund.

    Milton Friedman’s version of NIT was at 50% for low income ($20k), and then fairly low tax bracket rates (20%) above that. This means that the poorest people are taxed very high on income, and middle to high incomes pay a lower rate. Welfare and unemployment systems often use such a 50% clawback. It is a significant disincentive to work, unless you will make a lot during a year.

    Refundable tax credits is a similar system of permitting net refunds to people even if they pay no income taxes.
