Hello @yaso86
Yes, you can each take additional withholding from your salaries. This additional withholding will be reported on line 4c of your W-4 form. You and your spouse will each fill out your own W-4 form with your employer.
You can always use this W-4 Calculator to determine your estimated tax withholdings.
You can update your W-4 form anytime during the year with your employer.
Hope this helps!
