What changed this year, and why
For 2020, the self-employment tax rate on net earnings is 15.3%. The 15.3% rate is made of two parts: 12.4% for social security and 2.9% for Medicare. Both parts are charged on the same net earnings from self-employment, and only the social security part stops at the year’s wage base.
Common questions
- What are the two parts of the 2020 self-employment tax rate?
- The self-employment tax rate of 15.3% consists of 12.4% for social security and 2.9% for Medicare. The 12.4% social security part applies only up to the year’s social security wage base, while the 2.9% Medicare part applies to all net earnings from self-employment with no ceiling of its own.
The $400 threshold that makes Schedule SE mandatory
You must file Schedule SE (Form 1040) and pay self-employment tax if your net earnings from self-employment, excluding church employee income, were $400 or more in 2020. This $400 threshold is the bright line that turns self-employment activity into a filing obligation. Church employee income is handled under a separate, lower threshold and is not counted toward this $400 test. Once your net earnings reach $400, the full self-employment tax at the 15.3% rate (12.4% for Social Security and 2.9% for Medicare) is computed on 92.35% of those net earnings. The threshold applies regardless of whether the work was full-time or occasional, and regardless of whether you also have wages from a job where Social Security and Medicare taxes are already withheld. If you fall below $400, you do not file Schedule SE on that basis; if you are at or above it, you file and compute the tax due.
Your net earnings from self-employment (excluding church employee income) were $400 or more.

Church employee income is taxed from $108.28
Church employees have a special, lower threshold for self-employment tax. If your church employee income was $108.28 or more, you must pay SE tax and file Schedule SE (Form 1040). This threshold is much lower than what applies to regular self-employment earnings, because church employee income is treated as self-employment income for tax purposes even though you are technically an employee. The church does not withhold Social Security or Medicare taxes from your wages, so you are responsible for paying both the employer and employee share. Once you meet this $108.28 threshold, you compute your self-employment tax at the 15.3% rate (12.4% Social Security and 2.9% Medicare) on 92.35% of your net earnings. If your church employee income is below $108.28, you do not owe self-employment tax on that income.
You had church employee income of $108.28 or more.

Age and drawing benefits do not exempt you
You must pay self-employment tax on your net earnings regardless of your age. Even if you are already receiving social security or Medicare benefits, you still owe the 15.3% self-employment tax on your self-employment income. Many people mistakenly believe that once they reach retirement age or start collecting benefits, they are exempt from paying self-employment tax. That is not true. If your net earnings from self-employment meet the threshold, you must pay the full 15.3% rate (12.4% for social security and 2.9% for Medicare) on 92.35% of your net earnings. The only way to avoid this tax is to have no self-employment income or to fall below the applicable threshold. Age and benefit status do not provide any exemption from self-employment tax obligations.
The SE tax rules apply no matter how old you are and even if you are already receiving social secur- ity or Medicare benefits.

Half the tax comes back as an adjustment to income
Deduct one-half of your SE tax as an adjustment to income on line 14 of Schedule 1 (Form 1040). This means that after you calculate your full self-employment tax at the 15.3% rate (12.4% Social Security plus 2.9% Medicare) on 92.35% of your net earnings, you can claim half of that amount as an adjustment to your gross income on your individual income tax return. This deduction reduces your adjusted gross income, which in turn reduces your income tax liability. It is not a business expense and does not appear on Schedule C; it is an above-the-line adjustment. The deduction applies only to the income tax calculation and does not reduce your self-employment tax itself. This provision exists because the employer share of Social Security and Medicare is deductible for businesses, and this rule gives self-employed taxpayers a comparable benefit by allowing them to deduct one-half of the SE tax, which represents the employer-equivalent portion.

Only 92.35% of net earnings is actually taxed
To figure net earnings using the regular method, multiply your self-employment earnings by 92.35% (0.9235). This means that only 92.35% of your net earnings from self-employment is subject to the 15.3% self-employment tax rate (12.4% Social Security and 2.9% Medicare). The IRS applies this reduction because it represents the employer-equivalent portion of the tax. A regular employee does not pay Social Security and Medicare taxes on the employer's share of FICA; similarly, the IRS allows self-employed taxpayers to exclude a corresponding share from the tax base. The result appears on line 4a of Schedule SE (Form 1040). Net earnings figured using the regular method are also called actual net earnings. For example, if you had net self-employment earnings of any dollar amount, you would multiply that amount by 92.35% and pay the 15.3% tax on the product, not on the full amount.
To figure net earnings using the regular method, multiply your self-employment earnings by 92.35% (0.9235). For your net earnings figured using the regular method, see line 4a of your Schedule SE (Form 1040).

Nobody withholds it, so you pay it quarterly
When you are self-employed, no employer is withholding self-employment tax from your pay. Estimated tax payments. You generally have to make estimated tax payments if you expect to owe taxes, including self-employment tax (discussed later), of $1,000 or more when you file your return. This means you must calculate and pay your SE tax four times during the year, in quarterly installments, rather than waiting until you file your annual return. Use Form 1040-ES to figure and pay these installments. If you do not make sufficient estimated payments throughout the year, you may owe a penalty for underpayment. If you do owe $1,000 or more in total tax, including the 15.3% SE tax on 92.35% of your net earnings, you must plan for quarterly payments to avoid this penalty. If you expect to owe less than that threshold, you can pay the full amount when you file your return instead.
