Adjusting my W4 with two jobs

[rebeca]

I recently started a part-time job for the summer, but am beginning a new full-time job at the end of July (for which I already filled out the online W4 as single, one job). I'm a bit stumped on how to fill out my W4 for this current part-time job (in the case that I continue it throughout the year) and if I should adjust the W4 for the upcoming job! Unsure if I should just fill it out as "single, one job" for the time being and then when I officially start the full-time job in late July adjust my W4. And if I do wait, which W4 should I adjust (the full-time one and/or the part time one) and how? Sorry for all the questions! I super appreciate it!

Use the Tax Withholding Estimator on the IRS web site to figure out what to put on each W-4 form.

@rebeca - just foflow the instructions on the form.  it is fairly easy to follow. 

https://www.irs.gov/pub/irs-pdf/fw4.pdf

start with the higher paying job first.  Fill in lines 1C and read step 2C closely before completing the form.

on the lower paying job, simply complete step 1C as the instructions just above Step 3 recommend doing nothing further for the lower paying job.
