my fear would be if we tried to institue a national sales tax to replace the income tax, we get the sales tax, but income tax would stay too.
Not if you make repeal of income and payroll taxes coincident with the replacement.
John Linder (R Texas) offers a comprehensive bill to kill all income and payroll taxes outright, and provides an NRST as a replacement tax, not simply in addition to:
H.R.2525
SPONSOR: Rep Linder, John (introduced 07/17/2001)
A bill to promote freedom, fairness, and economic opportunity by repealing the income tax and other taxes, abolishing the Internal Revenue Service, and enacting a national retail sales tax to be administered primarily by the States.
