Payroll taxes are the taxes that employers are required to withhold from employees’ paychecks and remit to the government. Payroll tax is the combination of Social Security, Medicare, federal and state income taxes, and any other applicable local taxes. Calculating payroll taxes for employers involves collecting information from employees about their withholding amounts, registering with the IRS, verifying employee documents, calculating net pay, withholding taxes from each paycheck, remitting taxes accurately and on time to the relevant authorities, and documenting all payments and employer-issued documents for future reference. Calculating payroll taxes for employers can be a complex process, but thankfully there are several available software and services options that can help make it easier.
