Exemption from withholding. You may
claim exemption from withholding for 2018
if both of the following apply.
• For 2017 you had a right to a refund of all
federal income tax withheld because you
had no tax liability, and
• For 2018 you expect a refund of all
federal income tax withheld because you
expect to have no tax liability.
If you’re exempt, complete only lines 1, 2,
3, 4, and 7 and sign the form to validate it.
Your exemption for 2018 expires February
15, 2019. See Pub. 505, Tax Withholding

If you aren’t exempt, follow the rest of
these instructions to determine the number
of withholding allowances you should claim
for withholding for 2018 and any additional
amount of tax to have withheld. For regular
wages, withholding must be based on
allowances you claimed and may not be a
flat amount or percentage of wages.
You can also use the calculator at
www.irs.gov/W4App to determine your
tax withholding more accurately. Consider
using this calculator if you have a more
complicated tax situation, such as if you
have a working spouse, more than one job,
or a large amount of nonwage income
outside of your job. After your Form W-4
takes effect, you can also use this
calculator to see how the amount of tax
you’re having withheld compares to your
projected total tax for 2018. If you use the
calculator, you don’t need to complete any
of the worksheets for Form W-4.
Note that if you have too much tax
withheld, you will receive a refund when you
file your tax return. If you have too little tax
withheld, you will owe tax when you file your
tax return, and you might owe a penalty.
Filers with multiple jobs or working
spouses. If you have more than one job at

the Two-Earners/Multiple Jobs Worksheet
Nonwage income. If you have a large
amount of nonwage income, such as
interest or dividends, consider making
estimated tax payments using Form 1040-
ES, Estimated Tax for Individuals.
Otherwise, you might owe additional tax.
Or, you can use the Deductions,
Adjustments, and Other Income Worksheet
on page 3 or the calculator at www.irs.gov/
W4App to make sure you have enough tax
withheld from your paycheck. If you have
pension or annuity income, see Pub. 505 or
use the calculator at www.irs.gov/W4App
to find out if you should adjust your
withholding on Form W-4 or W-4P.
