$129.87 + State sales tax + local sales tax + city sales tax

Actually the tax is "of the gross payment".

Since all of those taxes are part of "the gross payment", following the letter of the law, it would have to be:
State sales tax + local sales tax + city sales tax + price TIMES the 0.30 fairtax rate

Actually the tax is "of the gross payment".

Which, as you have been repeatedly shown, does not include non-federal taxes. But why spoil a mediocre lie with facts?

State sales taxes in Illinois are calculated on the retail price. The local sales tax is not added to the portion taxed by the state. By definition, a sales tax is a tax on sales, not a tax on the taxes of sales.
