Self-Employment TaxCalculator

Use this calculator to estimate your self-employment taxes. Normally these taxes are withheld by your employer. However, if you are self-employed, operate a farm or are a church employee you may owe self-employment taxes. Please note that the self-employment tax is 12.4% for the FICA portion and 2.9% for Medicare.

Additional Medicare Tax

This calculator does not include any required amounts for the Additional Medicare Tax. This tax applies to a household and not an individual tax payer. Joint filers with over $250,000 in earned income, single filers with over $200,000 in earned income and married persons filing separately with over $125,000 in earned income will owe an additional 0.9% of the amount exceeding these thresholds. These thresholds are not index to inflation. This is paid only by the tax payer, there is no additional employer amount. This additional tax is calculated on your full tax return and while it is directly related to your earned income it is not calculated with your self-employment taxes.

Net Farm Income Or Loss

This is your net farm income or loss. This should include both the net farm profit or loss from Schedule F along with any income from farm partnerships. Please note that if your gross farm income is $2,400 or less and your net farm income is $1,733 or less there is a ‘Farm Optional Method’ for calculating income subject to self-employment taxes. If you qualify for this optional method it may produce a slightly lower income subject to self-employment taxes. This calculator assumes that you will not use the ‘Farm Optional Method’. For more information see IRS Schedule SE Part II, Optional Methods to Figure Net Earnings.
