Your tax rate increases if your income does. Yes, you'll get it back, if you're income doesn't put you through to the next tier. I tracked this closely with a coworker who shunned OT through my career, so I have first hand experience. We had similar deductions and he made almost as much as I did even though I far, far, outstripped him in OT. Maybe 100 hours over a given year.
It's easier to keep money that the taxman doesn't take than it is to get it back.
You can always make more money at UPS, or elsewhere. You can't make more time.
People think the higher tax bracket effects all of your income. The truth is that it will only effect the amount you earn in the higher bracket. If you were both in the 15% bracket which I think goes to roughly $50k, but you make another $5k in OT, the extra $5 Grand would then be taxed at 25%. So the difference in to making $5k more than your coworker would be paying an extra $500 over your regular tax rate.
You can't make more time but as someone earlier posted, the extra taxes you are paying aren't that big of a deal...Especially if you are maxing out your pension options.
