Because of changes in our tax system, the IRS is currently working on the new W-4, the 2018 withholding tables article from the IRS website can give you more information on this. However, if you want more taxes taken out, the number on G line should be small. The larger the number the less taken out, therefore, if you have a 1, you will be paying more taxes each month from your paycheck. Please use this information to help you decide. Below is an excerpt which was taken from the article I have included above.
The calculator and new Form W-4 can be used by employees who wish to update their withholding in response to the new law or changes in their personal circumstances in 2018, and by workers starting a new job. Until a new Form W-4 is issued, employees and employers should continue to use the 2017 Form W-4.
