2013 Federal & CA Updates

Social Security and Medicare Tax for 2013


The social security wage base for 2013 is $113,700. The social security tax rate remains at 6.2% for employers and reverts to 6.2% for employees and 1.45% for Medicare tax for employees and employers. There is no wage base limit for Medicare tax.

Beginning with wages paid in 2013, an additional 0.9% Medicare tax rate will apply to single employees who earn more than $200,000 and to married couples who file joint tax returns and earn more than $250,000. For high earners, therefore, the total Medicare tax rate will be 2.35%.

Tax Rate









NOTE: The 7.65% tax rate is the combined rate for Social Security and Medicare. The Social Security portion (OASDI) is 6.2% on earnings up to the applicable taxable maximum amount. The Medicare portion (HI) is 1.45% on all earnings.


Maximum Earnings Taxable:



Social Security (OASDI only)



Medicare (HI only)

No Limit

Federal Unemployment Tax (FUTA)


The FUTA tax rate is 6.0% of taxable wages as of

July 1, 2011. The taxable wage base is the first $7,000 paid in wages to each employee during a calendar year. Employers who pay the state unemployment tax, on a timely basis, will receive an offset credit of up to 5.4% regardless of the rate of tax they pay the state. Therefore, the net federal tax rate is generally 0.6% (6.0% - 5.4%). This would equate to a maximum of $42.00 per employee, per year (.006 X $7,000. = $42.00) in federal tax. State tax rates are based on requirements of state law.
