Paying for a Home

My question is, how do i reduce the amount of FED tax i pay on my paycheck, my take home after the 401k and taxes are like $3000/month
should i increase my allowance on w4 to 6? currently at only 3..I rather have my effective tax rate to like 25% and pay end of yr than pay the fed off the bat..any help pls thanks

I agree with the choice of paying only the minimum of withholding allowable, short of being penalized - I'd rather keep as much of my own money as long as I can. Other than that it is impossible to advise on tax reduction strategies with so little actual information. But, welcome to the pool.
