XI. Pedro Manalo, A Filipino citizen residing in Makati City, owns a vacation house and lot in San Francisco, California, U.S.A, which he acquired in 2000 for P15 million. On January 10, 2006 he sold said real property to Juan Mayaman, another Filipino citizen residing in Quezon City, for P20 million. On February 9, 2006 Manalo filed the capital gains tax return and paid P1.2 million representing 6% capital gain tax. Since Manalo did not derive any ordinary income, no income tax returnn was filed by him for 2006.
