@Val_B Thanks for the question! 

So the income from 2nd job is going to fluctuate throughout the year - this could mean you need to adjust your W4 more than once during the year. I would take your best estimate of how much you will make in the 2nd job for the year and add it to the rest of your number and input them on our W4 Calculator  That should let you know if you need to add to your withholdings on one of the jobs. 

Hope that helps!
