Worked fine for me just now.

There was a notice up there a couple of days ago saying that there was scheduled maintenance. I didn't pay too much attention to it (presumably it was after-hours), but it could be related.

I have had SOOOO many problems with the IRD website. It's now totally broke for me. Initially I could keep retrying and it would work. Then that stopped saying I had an invalid username/password. I tried another browser and that worked and now all browsers say I have a the wrong password, even if I reset.... Perhaps they don't want me to pay tax?

Fixed it now. I just needed to clear my browser cache for google chrome.

I did try and installed Firefox and had the same error message but worked when I was incognito/Private mode.
