Karl August and Maria Ana had four children:

Princess Clotilde of Thurn and Taxis (30 November 1922 – 1 September 2009) married Prince Hans-Moritz of Liechtenstein (son of Prince Alfred Roman of Liechtenstein).

After his marriage, Karl August and his wife resided at Schloss Höfling in Regensburg where he managed the family's agricultural interests in nearby Burgweinting. As a committed opponent to Nazism, Karl August forbade his children, after the Machtergreifung, to join the Hitler Youth.
