Just got done with my 2016 taxes. I am good for 2016, but my amount of write offs for next year are going to change a bit, so I want to take out an extra $200 per month (I HATE owing and like coming as close to break even point as possible). I work 2 jobs, one of which is a salary job and the other is paid by the amount of work I do. I would like to keep my salary tax situation the same but take an extra $200 out of the other job. It looks like on the W4 form there is an area that says "Additional amount, if any, you want withheld from each paycheck". So instead of me working through the calculations of changing my deductions, would this actually be the easiest way to just take out an extra $200 per month?

TIA!!!
