Keystone is a town in the Black Hills region of Pennington County, South Dakota, United States. The population was 311 at the 2000 census. It had its origins in 1883 as a mining town, and has since transformed itself into a resort town, serving the needs of the millions of visitors to Mount Rushmore National Memorial, which is located just beyond city limits. Among its tourist attractions is the Black Hills Central Railroad, built in 1900 for Black Hills gold. It now operates passenger trains pulled by preserved steam locomotives. Carrie Ingalls spent a significant part of her adult life here, living with her husband David N. Swanzey and his children. Her sister Mary Ingalls lived with them for a while and died here in 1928.
What is tax law?
Tax law is the codified system of laws that describes taxes on economic transactions. Tax attorneys advise and represent individuals and businesses on all types of tax issues -- including income tax, payroll tax, property tax, and estate and gift taxes. Tax attorneys ensure that their clients are in compliance with federal and state laws and regulations, and represent taxpayers in enforcement proceedings initiated by the Internal Revenue Service (IRS) and/or state taxation agencies.
