As you gather and review all the paperwork needed for filing your federal tax return you may begin to have concerns for your withholding. IRS Spokesman Michael Devine says use their Withholding Estimator to get a sense of where you are and if you will need to pay in.
Devine says if you do your taxes early using the filing software and find you need to pay in, you can still file your taxes early and schedule the payment.
He says all of the information is on the IRS website. Go to IRS.GOV.
