After reading Bruce Bartlett’s newest critique of the FairTax, I decided to test the claim of the FairTax that the prebate will exempt all expenditures up to the poverty level. According to the FAQ, “All valid Social Security cardholders who are U.S. residents receive a monthly prebate equivalent to the FairTax paid on essential goods and services, also known as the poverty level expenditures.” According to the table, the poverty level for a single person is $10,400 and the prebate is calculated at 23% of that number for $2,392.
At first, I thought that was the end of it. If you made and spent $10,400, then you would pay $2,392 in sales taxes on $8,008 in purchases. But no worry, because you’d get a prebate check to reimburse that $2,392, giving you an effective tax rate of 0%. Right?
Wrong. I realized that the extra $2,392 in prebate check is not the full amount given back to the taxpayer. Why? Because that $2,392 is also taxed when spent. $550.16 is taxed from the prebate. So what is the rate if you made the poverty level wage?
5.29% is the rate. This is found by adding your income and prebate together and multiplying that by 77% to get your take-home pay ($10,400+$2,392 = $12,792 * 77% = $9,849.84). Divide take-home pay by your wage and subtract that from 1 and you get the effective tax rate (1 - $9,849.84 / $10,400 = 5.29%)
So the claim that the prebate set by the FairTax formula will exempt poverty level expenditures is a flat-out fraud. What is the actual rate to exempt poverty-level expenditures? It is the tax-exclusive rate of 29.87%. The new prebate level using this rate is $3,106.49 ($10,400 * 29.87%), which added to $10,400 gives you $13,506.49 in before tax pay and after tax pay will be $10,400. So just set the rate higher and the problem is fixed, right?
Wrong! Why is this? Because, if you didn’t notice, spending on prebates will go up (it will increase 29.87% to be exact). To get the same level of government “services,” you will have to increase the tax rate to compensate for the increased prebate. So the rate will increase, but since the prebate is set by the rate, it will also increase, and then the rate would have to increase again, so on and so on, ad infinitum.
So it is impossible to exempt the poverty level expenditures from tax using the FairTax formula. The FairTaxers will just have to admit that the effective tax rate on poverty-level expenditures at the established amounts is 5.29%, and that it can never be 0%.
