Expected Performance of the ATLAS Inner Tracker at the High Luminosity LHC

The expected performance of the ATLAS ITk is presented. The performance is evaluated on different dedicated MC samples, where for some samples minimum bias events with an average number of 190-210 p-p interactions per bunch crossing is added. The performance is evaluated in terms of reconstruction efficiency for prompt tracks in different environments and tracks from converted photons, as well as track parameter resolutions. This presentation is primarily based on ATL-PHYS-PUB-2016-025
