The high-luminosity phase of LHC operations (HL-LHC), willfeature a large increase in simultaneous proton-proton interactionsper bunch crossing up to 200, compared with a typical levelingtarget of 64 in Run 3. Such an increase will create a verychallenging environment in which to perform charged particletrajectory reconstruction, a task crucial for the success of theATLAS physics program, and will exceed the capabilities of thecurrent ATLAS Inner Detector (ID). A new all-silicon Inner Tracker(ITk) will replace the current ID in time for the start of the HL-LHC. To ensure successful use of the ITk capabilities in Run 4and beyond, the ATLAS tracking software has been successfullyadapted to achieve state-of-the-art track reconstruction inchallenging high-luminosity conditions with the ITk detector. Thispaper presents the expected tracking performance of the ATLAS ITk based on the latest available developments since the ITk technical design reports.
