I assume the FICA tax is not considered income tax.
So income tax to be paid is as follows:
0-3500 : exemption, so net taxable income = 25000-3500=21500
0-8025: at 10%, so $802.50
8025 to 21500: at 15%, so (21500-8025)*0.15=13475*0.15=2021.25
Total income tax due = 802.50+2021.25=$2823.75
If FICA tax is included, then tax rate is 7.65%, or
FICA tax = 25000*0.0765=1912.50 (to be added to income tax above, if necessary).
