Getting tax withholdings right can be extremely daunting. Failure to pay the IRS or state taxing authority the correct amount could end up costing you thousands of dollars in penalties and interest. For many employers, an outright failure to pay could result in personal liability for employment taxes.
Payroll tax withholding covers more than just federal taxes. It also addresses any state tax obligations, local tax requirements, and Federal Insurance Contributions Act (FICA) Taxes. If you, as an employer, do not pay these correctly, you could have both the federal and state taxing authorities upset with you, and your employee may have to pay into the government at the end of the year. You can avoid all of these potential problems by simply ensuring that you are withholding for everything you are supposed to—in the right amount.
