As an accountant or tax agent, you're likely to encounter login issues with the ATO's TAP (Tax Agent Portal). These login problems occur regularly due to system updates. The quickest workaround is using an Incognito Window in your browser - if this works, it indicates a browser cache or cookie issue.

If you prefer not to use Incognito mode, follow the browser-specific steps below to resolve the issue.
