The new W-4 form keeps the withhold such that your tax refund should be as close to zero as possible after taking the credits into consideration. SOOOO .... look at last year's refund and the reduced withholding times the rest of the pay periods + the prior withholding ... do they equal about the same amount ? If you want to increase your withholding to increase your refund then you can either remove one or both of the kids on the W-4 and/or add a static amount to line 4C to be withheld in addition to the regular withholding amount per pay period.
