How much self-employment tax will I pay?
Self employment taxes are comprised of two parts: Social Security and Medicare. For 2011, you will pay 4.2 percent and your employer will pay Social Security taxes of 6.2 percent on the first $106,800 of your covered wages. You each also pay Medicare taxes of 1.45 percent on all your wages – no limit. If you are self-employed, your Social Security tax rate is 10.4 percent and your Medicare tax is 2.9 percent on those same amounts of earnings but you are able to deduct the employer portion.
