$383.76 should be withheld from his $2965 gross pay over 2 weeks.

2014 WEEKLY TAX TABLE
OVER          BUT NOT OVER  BASE TAX       RATE         
     87.00
                   436.00                   -   10% OVER 87 
     
   436.00
                1,506.00            34.90  + 15% OVER 436 
  
1,506.00
                3,523.00          195.40  + 25% OVER 1506 
   3,523.00                 7,254.00          699.65  + 28% OVER 3523 

Since, $2965 is for 2 weeks, we need to divide his pay by 2 to get his weekly pay.

2965 / 2 = 1482.50 per week.

1482.50 is OVER 436 BUT NOT OVER 1506. Therefore, his base tax for the week is 34.90 + 15% OVER 436.

1482.50 - 436 = 1046.50 * 15% = 156.98 + 34.90 = 191.88 tax withheld for the week.

The tax withheld 191.88 should be multiplied by 2 to get the tax withheld for the pay period of 2 weeks.

191.88 * 2 = 383.76 should be withheld from his $2965 gross pay over the last 2 weeks.
