Things You'll Need:
- IRS Form W-4
-
Step 1
Obtain a copy of IRS Form W-4. It is available at www.IRS.gov (see Additional Resources) or by telephoning (800) 829-1040.
-
Step 2
Follow the instructions and complete form W-4. To withhold less, either decrease the number of allowances on line 5 or decrease the additional amount being held on line 6. To withhold more, increase the number of allowances on line 5 or increase the additional amount held on line 6.
-
Step 3
Sign and date your W-4, and then return it to your employer. Federal law no longer mandates that W-4 forms be sent to the IRS, but they must be available for inspection if necessary.
