Hi HertzFam, great idea to plan ahead now for not having the child tax credit or the other dependent credit. You will want to submit an updated Form W-4 to your employer. There is a W-4 Calculator that will take you through step-by-step,

Once you complete the form, give it to your employer. Then, keep a close eye on your next few paychecks to see how the changes impacted your federal income tax withholding. You should see more tax withheld after removing the dependent from your Form W-4.
I hope this is helpful!
