There are hundreds of factors that impact your withholding and any refund or payment: age of children, physical conditions, investments, loan payoffs, and whether or not you were affected by COVID for starters.
The IRS provides an online estimator.
As the IRS estimator limits values to federal withholding, this does not take into account your local, state, or other specific withholdings. Use this at your own risk if determining comprehensive estimated payments throughout the year. We are more than happy to forecast next year’s liabilities so surprise fees are minimized.
