IRS Form 941

Federal law requires you, as an employer, to withhold taxes from your employees' pay. Each time you pay wages, you must withhold or take out of your employees' pay certain amounts for federal income tax, social security tax, and Medicare tax. You must also withhold Additional Medicare Tax from wages you pay to an employee in excess of $200,000 in a calendar year. Under the withholding system, taxes withheld from your employees are credited to your employees in payment of their tax liabilities. Federal law also requires you to pay any liability for the employer's portion of social security and Medicare taxes. This portion of social security and Medicare taxes is not withheld from employees.
