As said before, just use the first IRS W-4 withholding link. Do not try to micro manege a W-4. Just list the number of dependents and filing status. It is better to be over withheld then under withheld or you will owe tax at the end of the year. Don't even consider things like child tax credit - you may or may not even qualify for it - if you do then you will just get a larger refund and you can adjust next years W-4 accordingly. Since W-4 withholding is based on a year and this year is more than half over it is difficult to predict a W-4 to allow for past earnings and future earnings and to account for low withholding at the start of a new job. When there will only be a few months pay, the type and amounts of any credits you might get are very difficult to predict and can be very different when there is a full years pay - many credits depend on the amount of income and disappear with either low or high income - (child tax credit and EIC for example.)
