No federal withholding

@Kp08 

That's not unusual. The $4,000 child tax credit from Step 3 of your W-4 is divided by the number of pay periods in a year and then that amount is credited against any federal withholding. So, for example, if your employer has 26 pay periods in a year, you get a credit of $154 per pay period ($4,000/26) credit towards your federal income tax.  That's a massive credit. 

If you look up the tax withholding tables in IRS Publication 15-T, you will see that if you are married filing jointly, you would need to have a biweekly paycheck of at least $2,395 ($62,270/yr) before a dime of federal income tax is withheld.  If you're head of household, you would need a biweekly paycheck of $2,120 ($55,120/yr) before a dime in federal income tax is withheld.  

So instead of the $4000 in that box I need to have the divided account based on the salary?  This is just too much, never had these issues with old format. 

Just to be on the safe side I want will submit a additional withholding from 4c, because after reading some other community post I do not want to be that person with a tax bill next year.
