As an example, once you, the student, make over ~7000 a year, it starts to impact financial aid options. (Obviously, the higher you go, the more the impact is.) When I started working too many hours in the summer/weekends it definitely had an impact on my aid even 20 years ago. [0]
[0] - Semi related protip; If you are engaged to someone and they are still going to college, waiting until they graduate to get married may qualify as a good idea financially. This cost me a lot in the short run and my now-ex wife a lot in the long run.
But I already had a plan. That's very important. When I got to the end I'd re-enrolled and started back right where I'd stopped. I had a job for 8 months and a trip for four.
It did put my out of sync a bit with the kids I'd started with, but that was no big deal (and in some ways I was ahead). Otherwise school has its own calendar so it was no big deal.
Another self-inflicted problem: by my last semester, due to my work during the time off leading to work over the summer, was that I had a full time job thousands of miles from school. As a result I didn't finish my last semester in the last semester and had to pay for an extra one just to take one class. And I was pressured by my team at work to drop out and not worry about it ("You already have a good job"). So glad I didn't listen to them!
I started college at 20, and dropped out a year later to pursue other things. Although I got into the industry through my own self-learning, it took me a full 20 years more to finally get my Bachelors.
It will be a major challenge to go back into school if you leave. Not from an administrative standpoint (probably) but definitely from a social-economic one. Once you get started into your career, it can be very hard to reorient yourself back into academics. For me, I had the hardest time coping with the Sisyphusian nature of school, where so much of it felt like "what's the point of this?" when the real world often had real rewards.
You've got the rest of your life to upskill and work (seriously, you'll move jobs frequently, and you'll always be learning stuff.) Maybe more than you want to. Enjoy this situation right now. It doesn't come around again.
