WHAT IS FICA?

What's FICA ?

If you're a wage or salaried employee, your employer picks up half of this tax burden.

Under the Federal Insurance Contributions Act (FICA), 12.4 percent of your earned income up to an annual limit must be paid into Social Security, and an additional 2.9 percent must be paid into Medicare.

That limit is $94,200 for the 2006 tax year and rises to $97,500 for the 2007 tax year.

There are no earned income limits on Medicare taxes - so even if your salary is well above the cap for Social Security tax, you will still owe Medicare tax on your total earned income.

If you're a wage or salaried employee, you pay only half the FICA bill (6.2 percent for Social Security plus 1.45 percent for Medicare), and the tax is automatically withheld.

Your employer contributes the other half.

For most people that means 7.65 percent of their paycheck is withheld and their company pays another 7.65 percent on their behalf.

If you're self-employed, however, you're expected to cough up both the employee and the employer share of FICA. You are, however, permitted to deduct half of this self-employment tax as a business expense.
