What if tax season hit tomorrow - could your wallet take it?

I was just thinking, imagine if suddenly the government decided tax day was tomorrow instead of months away. Like, no warning, just boom - time to pay up. Honestly, I'd be scrambling big time. I know it's smart to set aside money each month, but life happens and sometimes I'm like "eh, I'll catch up next paycheck." Anyone else feel like they'd be totally unprepared or am I just terrible at adulting, haha?
