Question:  The Kansas City Power & Light District includes the headquarters of what tax prep company?
Context: Arthur Wayland "Art" Ellison (1899–1994) was an actor and director who worked for the Kansas City Power and Light Company for forty-eight years before becoming a professional actor.  Prior to that, he had appeared in scores of amateur stage productions in the Kansas City area.  He was born in Potsdam, New York and he died in Kansas City, Missouri.  Director Herk Harvey speculated that Art Ellison had acted in more industrial and educational films than any other, including some directed by a young Robert Altman.  He is best known for his part in the 1962 cult-classic horror film "Carnival of Souls". The Kansas City Power & Light District or Power & Light District or P&L is a dining, shopping, office and entertainment district in Downtown Kansas City, Missouri, United States, developed by The Cordish Companies of Baltimore, Maryland and designed by Beyer Blinder Belle and 360 Architecture.  The district comprises nine blocks on the south side of the downtown loop.  It is located between Baltimore Avenue to the west, Grand Boulevard to the east, 12th Street to the north, and Interstate 670 to the south.  The $850 million mixed use district is one of the largest development projects in the Midwestern United States, and is anchored by the renovated Midland Theatre, Alamo Drafthouse Mainstreet Cinema and the world headquarters of H&R Block. Kansas City Power and Light Company is an electric utility company serving the Kansas City metropolitan area.  It is a wholly owned subsidiary of Great Plains Energy Incorporated of which it is the biggest component.  The company traces its roots to November 1881 when Joseph S. Chick obtained the exclusive rights to use the Thompson-Houston arc lighting system in the counties of Jackson, Missouri, and Wyandotte, Kansas, for $4,000.  The following month, the initial franchise to establish an electric works in the City of Kansas, Mo., was granted to Lysander R. Moore and later assigned to "Kawsmouth Electric Light Company".  Construction was begun in February 1882 on a power plant on a tract of land at the southeast corner of 8th and Santa Fe Streets in the West Bottoms.  Kawsmouth Electric Light Company built quickly and, on Saturday night, May 13, 1882, brought electric illumination to the first 13 customers on the west side of Main Street in the downtown district.  In 1885 the company reincorporated as "Kansas City Electric Light Company". The Kansas City Power and Light Building (also called the KCP&L Building and the Power and Light Building) is a landmark skyscraper located in Downtown Kansas City, Missouri.  The building was constructed by Kansas City Power and Light in 1931, as a way to promote new jobs in Downtown Kansas City.  Since then, the Art Deco structure has been a prominent part of the Kansas City skyline.  The structure was the tallest building west of the Mississippi River upon its completion after succeeding the Smith Tower until completion of the Space Needle in 1962.  The east side of the building faces the Power & Light District which bears its name, and the building's iconic lantern appears on promotional materials and signage for the district and even Kansas City as a whole. H&R Block is an American tax preparation company in North America, Australia, and India.  The Kansas City-based company also offers payroll, and business consulting services. The Jenkins Music Company Building in Kansas City, Missouri was built in 1911 at 1217-1223 Walnut Street, located in the Kansas City Power and Light District.

It was listed on the National Register of Historic Places in 1979. The 1201 Walnut Building is a Skyscraper located in Downtown Kansas City, Missouri, USA, built by HNTB Architects in 1991.  Found at the intersection of 12th and Walnut streets, it is the eighth tallest habitable structure in the Kansas City Metropolitan Area, and the twelfth-tallest habitable structure in Missouri, at 427 feet.  The exterior is made of mostly dark-colored glass, and granite panels, and is very close the new Sprint Center and Power & Light District, part of the redevelopment of downtown Kansas City.  The glass look helps to further the glass-theme that the Sprint Center, H&R Block Building, and the "Kansas City Star" printing press have.  In late 2010, building tenant Stinson Morrison Hecker, LLP acquired the rights to place a large sign and corporate logo atop the southern face of the building.
