Florida is one of the few states that does not require employees to pay state income tax. While some city and local governments in other states mandate employees to pay city and local income tax, Florida does not require its employees to pay those taxes either. As a Florida employee, you are required to pay federal taxes, which are based on a percentage of your wages.
Medicare tax is a federal payroll tax that employers and employees in the United States pay. Your employer is supposed to withhold Medicare tax at the rate the federal government sets. As of 2011, you pay 1.45 percent of all your taxable wages for Medicare tax. Your taxable wages is your pay after your employer subtracts nontaxable deductions, such as a Section 125 medical or dental plan. If you do not have nontaxable deductions, all of your wages are subject to Medicare tax.
Social Security Tax
Social Security tax is a federal payroll tax that employers and employees pay. The federal government sets the Social Security tax percentage and the annual wage limit. For 2011, you pay 4.2 percent of your taxable wages for Social Security tax, up to $106,800 for the year. If you have no nontaxable deductions, all of your wages are subject to Social Security tax.
Federal Income Tax
Federal income tax is a tax that the federal government levies on personal income. Your federal income tax withholding is based on the IRS withholding tax tables (Circular E) and your W-4 form data. Your employer obtains your filing status and allowances from your W-4 and uses the withholding tax table that matches your W-4 information, wages and pay period. This method is the wage bracket method, which gives a flat amount to withhold.
The other method is the percentage method. Your employer obtains your number of allowances from your W-4 and determines the total sum based on the amount the IRS gives for each allowance (see page 35 of IRS Circular E). Your employer subtracts your allowance sum from your wages after it subtracts nontaxable deductions and pretax deductions, such as a traditional 401k plan, from your gross pay. Then it uses the percentage method table (see page 36 of IRS Circular E) relevant to your filing status, pay period and wages after allowances to figure your withholding.
Your employer is supposed to report your annual taxes withheld and wages earned to the Social Security Administration via Form W-2. Unlike employees in states that charge state income tax, your Florida employer does not have to file your W-2 with the state since you paid no state income tax. Therefore, when you file your tax return, you file it only with the IRS.
