For clarification, I'm adding this definition of disposable income:
Disposable personal income is total personal income minus personal current taxes.
Personal current taxes is tax payments (net of refunds) that are made by persons and that are not chargeable to business expense and certain other payments by persons to government agencies (except government enterprises) that are treated like taxes.
Personal current taxes includes taxes on income, including realized net capital gains, and on personal property. Also included in personal taxes are personal licenses. Contributions for government social insurance are not included.
Q. Are sales taxes included in the calculation of disposable personal income?
A. No. Disposable personal income is personal income less personal current taxes. Personal current taxes consists of income taxes, motor vehicle licenses, and personal property taxes.
Q. Do you have disposable personal income by county?
A. No. It is not available from any Federal statistical agency.
All state and local area dollar estimates are in current dollars (not adjusted for inflation).
