NYC vs. NJ commuter math
NJ commuter working in NYC pays NY non-resident tax on NY-source income (no NYC tax), then NJ resident tax with a credit for NY tax paid. Net: similar combined burden but no NYC tax. The savings is rent, not taxes.
The NY 'true-up' trap
NY underwithholds bonuses at 11.7% supplemental rate. If you're in the 9.65%+ bracket, you owe more at filing. Adjust withholding via IT-2104 to avoid April surprise.
Tax-loss harvesting hits differently in NY
NY follows federal for capital losses ($3K annual offset against ordinary income). NYC also follows. RSU sell-to-cover plus harvesting in a brokerage account can reduce both NY and NYC tax simultaneously.
