Up until 1998 the tallest building status was essentially uncontested. Counting buildings as structures with floors throughout, New York City's World Trade Center was the tallest including the antennas, Sears Tower in Chicago excluding the antennas. As antennas were usually excluded, Sears Tower was counted as the tallest. When Petronas Twin Towers in Kuala Lumpur, Malaysia was built, some felt that the "spire" extending to 9 meters higher than the roof of the Sears Tower was just added to "cheat" its way into the spot as tallest building. Excluding the spire, the Petronas Towers were not taller than the Sears Tower. Therefore, before the Petronas Towers were completed, the Council on Tall Buildings and Urban Habitat defined four categories in which the "world's tallest building" can be measured:
Height to the structural or architectural top (including spires and pinnacles, but not antennas, masts or flagpoles)
Height to the highest occupied floor
Height to the top of the roof
Height to the top of antenna
The height is measured from the sidewalk level of the main entrance. In all of these categories, Sears Tower had held the top spot. After Petronas was built, Sears Tower became second in the first category only.
On April 20, 2004, the Taipei 101 in Taipei, Taiwan was completed. Its completion gave it the record for the first three categories.
The Sears Tower still leads in the fourth category with 527 m (1,729 ft

It depends on who does the measuring! Skyscraper buffs disagree on whether features like flagpoles, antennas, and spires should be included when measuring building height.
Also under dispute is the question of what, exactly, constitutes a building. Technically, observation towers and communications towers are considered structures, not buildings, because they are not habitable. They do not have residential or office space.
Soaring 1,670 feet (509 meters), the Taipei 101 Tower in Taipei, Taiwan appears to be the world's tallest building. But the Taipei 101 Tower's massive 60-foot spire contributes to much of that height.
Before the Taipei 101 Tower was completed, the Petronas Twin Towers in Kuala Lumpur, Malaysia were described as the tallest buildings in the world.
But, like the Taipei 101 Tower, the Petronas Twin Towers get much of their height from spires, not from usable space.
If you count only habitable space and measure from the sidewalk level of the main entrance to the structural top of building (excluding flagpoles and spires), then Chicago's Sears Tower, built in 1974, may still be the tallest building in the world.
But none of these buildings will keep their rankings for long. Even taller buildings are on the drawing board. Freedom Tower at the new World Trade Center in New York City is expected to rise 541 meters (1,776 feet) tall, including its enormous spire.
However, if spires, flagpoles, and antennas can be counted when we measure building heights, perhaps rankings of the World's Tallest Buildings should include all man-made structures, whether or not they contain habitable space. In this case, the CN Tower in Canada is the world's tallest building. The communications tower and tourist attraction measures 553.33 meters (1,815 ft., 5 inches) tall.

Right now the Burj Dubai is being built in Dubai, of the UAE.
That will be the tallest building in the world when completed, at 2313ft
But right now its Taipei 101. In Taipei, Taiwan standing at 1,670 ft, and 101 stories tall.
Unless you count the CN Tower in Toronto, which is 1815 ft tall.

It depends upon your definition of the word "building". If you mean the tallest building with the highest floor used for the bldg's purpose (in other words, a floor used as office space in an office bldg), the answer is the Sears Tower in Chicago, IL, US. Some of the other contenders for "tallest building" have ornamental structures on top like spires, etc to get the max height, but their highest floor of usable space is not as far up as Sears.
