This question always baffles me. Maybe it's just because I haven't read anywhere that the 61 day is the magic number, other than having to wait until you had the card for at least 60 days. If you are not exactly sure, why not just wait until the 16th, (Friday) or even Monday, just to make sure? Can someone chime in as to whether that exact 61 day date is the exact day you must request the CLI on or if not, the window shuts?
The reason I am asking is because using mine as an example, my 61st day is Jan 22, but I had already set a reminder for me to request mine later that weekend or Monday because my BCE statement close date is the 23rd and I thought it made more sense to let that second statement close.
I had the same question too, and I think it just opens at day 61, its not only open for 1 day. 
Is there any downside to if AMEX requests tax information? Do they just want proof of my income? Any downsides?

Yeah that's what I was thinking about the 61 days. As far as the tax information, I am one of those that originally was in the camp of "what's the big deal, just provide it". However, after I thought about it, it seems way more intrusive than necessary and I never want to play that relationship with them. They could check income via other means and there is some info we could redact by other means. The way I understand it, they normally want to have access to your tax information themselves, all of it.
