At the foundation of any properly-planned federal tax return, is the Employee's Withholding Allowance Certificate, or Form W-4 as most people know it. Especially with the sweeping 2018 tax laws, it might be best if you consult with us as to what should be changed.As a rule of thumb, it never hurts to review the information on your W-4 each year before preparing to file your taxes in New York. This is especially true if you had a sizable tax refund the previous year, or owed a significant payment amount. If your household or income changed, be sure to make any needed adjustments on your W-4.
