Tai Seng MRT station is an underground Mass Rapid Transit (MRT) station on the Circle line, situated along the boundary of Hougang and Toa Payoh planning areas, Singapore.

[citation needed] Before the station was built, it was tentatively named Upper Paya Lebar.

[3] On 16 May 2017, it was announced that Tai Seng MRT station on the Circle line will be linked by an underground walkway to the bustling Paya Lebar industrial and commercial hub called 18 Tai Seng on the other side of the road.

The station was the only station on the eastern stretch of the line that did not have an underground link to the other side of Upper Paya Lebar Road, where 18 Tai Seng, J'Forte, Sakae Building, BreadTalk IHQ, RE&S Building, Charles & Keith Building and Jackson Design Hub (Tupperware) are located.

Work on the new Exit C leading to the underground walkway started in March 2015 and was completed on 7 December 2017.
