As stated on the W-4 that you give to your employer for tax withholding -https://www.irs.gov/pub/irs-pdf/fw4.pdf
I claim exemption from withholding for 2019, and I certify that I meet both of the following conditions for exemption.
• Last year I had a right to a refund of all federal income tax withheld because I had no tax liability, and
• This year I expect a refund of all federal income tax withheld because I expect to have no tax liability
If this applies to you then write Exempt on the W-4, otherwise enter the number of allowances on the W-4
