I am starting a new job on 1/9/2012 where I will be making significantly more money than I did in 2011. Further, I do not have certain deductions that I have in the past (mainly $12,000 per year in tuition expenses to write off).
I am looking for a resource where I can determine how to select withholding allowance to set the amount of a rebate/payment near to $0 come tax time in 2013. My goal is to optimize contributions to 401k as well as setting the proper withholding allowance to maximize the amount of my semi-monthly check and get as close to $0 come tax time in 2013 as possible. My situation is fairly simple. Assume interest expense on my mortgage as the main deduction with no other income or special situations.
Is anyone aware of a good online (preferably free) resource for tax planning in this way?
