Quick Background on Payroll Taxes
The Federal Insurance Contributions Act (FICA) imposes two taxes on employers, employees, and self-employed people. One tax is the Old Age, Survivors and Disability Insurance (OASDI, commonly known as the Social Security tax). The other tax is for Hospital Insurance (more commonly known as Medicare A). The Social Security tax has been 6.2% and the Medicare tax has been 1.45%. An employee pays the 6.2% Social Security Tax on her first $110,100 of wages (this wage base changes periodically), and pays the 1.45% Medicare Tax on all wages without limit. The employer must match employees’ Social Security and Medicare Tax contributions. Therefore, the employee pays a combined Social Security and Medicare tax rate of 7.65% of wages and the employer matches this 7.65% contribution for a combined FICA rate of 15.3%.
Self employed people pay both employer and employee portions of the tax on their self employment income. The self-employment rate has been 15.3%. There are two adjustments that self employed people make that are related to self employment tax:
- The first adjustment is to multiply self-employment income by 0.9235. This adjustment basically allows the employer portion of FICA taxes to be deducted from self employment income. Notice that the 0.9235 number is equal to 1 – 7.65%. 7.65% representing the employer portion of FICA
Example: Joan has $100,000 of self employment income from her proprietorship. She multiplies this income by 0.9235 and the product is $92,350, which is equal to her $100,000 self employment income less the employer portion of 7.65%. The self employment tax rate of 15.3% is then multiplied by $92,350 to arrive at self employment tax of $14,129.
- The second adjustment is a deduction equal to one-half of the self employment tax on the self employed person’s tax return.
On Joan’s personal tax return, she would be allowed an above the line deduction of $7,064.50 (one half of the $14,129 self employment tax).
What’s New
During 2011, the employee portion of Social Security was reduced to 4.2% from 6.2%. The Social Security tax for self-employed individuals was 10.4% (6.2% employer portion plus 4.2% employee portion). In December 2011, when Congress couldn’t agree on how to fund a full-year extension of the payroll tax cut, it passed the Temporary Payroll Tax Cut Continuation Act of 2011 that provided a two month extension of the 4.2% employee Social Security rate. On February 17, Congress passed the Middle Class Tax Relief and Job Creation Act of 2012. This new law extended both the 4.2% Social Security employee portion and the 10.4% Social Security portion of self employment tax until December 31, 2012.
The maximum savings for 2012 will be $2,202 (2% of $110,100) per taxpayer. If both spouses earn at least as much as the wage base, the maximum savings will be $4,404.
An additional change is made for the above the line deduction for self employment tax. The deduction is normally one half of the self employment tax to reflect the half that represents the employer portion of the tax. However, the employee portion of the Social Security tax is 4.2% while the employer portion of the Social Security tax is 6.2%. Thus, the deduction for Social Security tax is now 59.6% [6.2% employer portion divided by combined employer and employee Social Security tax of 10.4%]. The deduction for the Medicare portion of the self employment tax remains at 50% since the 2% reduction applied only to the Social Security Tax.
Example: It is now 2012 and Joan still has $100,000 in self employment income. The first adjustment is still to multiply her $100,000 income by 0.9235. The product of $92,350 is multiplied by the Social Security portion of self employment tax of 10.4% to arrive at $9,604.40. The $92,350 is also multiplied by the Medicare portion of self employment tax of 2.9% to arrive at $2,678.15 for a total self employment tax of $12,282.55. Notice that the self employment tax is less than the first example by $1,846.45. This difference is due to the 2% reduction in the Social Security portion of self employment tax times the self employment income of $92,350.
To calculate Joan’s above the line deduction:
- multiply the Social Security portion of self employment tax by 59.6% ($9.604.40 times 59.6% equals $5,724.22)
- multiply the Medicare portion of self employment tax by 50% ($2,678.15 times 50% equals $1,339.08)
- Joan’s total above the line deduction for self employment tax is $7,063.30.
