Give the Form to Your Employer. Fill out the rest of the Form W-4 and give it to your employer. If you're starting a new job, he'll use this information to calculate the tax withholding on your first paycheck.How many dependents can you claim on W4?
You have zero dependents and only one job, so ideally the total number of allowances you’re claiming would be two. On your W-4 form, you would write a “1” beside line A and a “1” next to line D under the Personal Allowances Worksheet. You could choose to claim zero tax allowances.
