Not my business, but I'm wondering about those numbers and trying to put it in perspective.
The 28% bracket starts at $87K, so if most of your earned money is in the 28% bracket, you must be making twice that. Pretty sweet for a part time gig!
SS stops being taxed around $113K, so the expiration of the SS payroll tax break is going to cost you less than $2300. Is that really a deal breaker at your income level, or just the push out the door you are looking for? The latter is certainly fine, but let's call it what it is.
Even ignoring when SS tax stops and that some of your income is taxed at less than 28%, 28% fed+7.65% SSA + 6% state is just under \42%. I don't know what these other taxes are and what the pension tax credit loss amounts to, but it sounds like your transportation costs must be enormous! Just saying it doesn't seem to add up. If you are talking about property taxes, that has nothing to do with income.
Are you maybe counting 401K and ESPP deductions in that 70% not taken home? You may not be able to spend that money on groceries today, but eventually you will be able to, so that's not really right to take those amounts away from what you call earned money.
If you really didn't want to get into this, I can delete this. It wasn't really to pick on you, but when I saw a follow up comment that there's not much incentive for single people to work, I felt like it was overblown. It's a 2% increase, and really less than that since there's a cap, and it just gets you back to where you were before the decrease.
