How it works
Set aside = your profit x the share you choose. Putting it in a separate savings account means the money is there when tax is due.
Self-employment tax = profit x 92.35% x 15.3%. The 15.3% is 12.4% Social Security plus 2.9% Medicare, and it is worked out on 92.35% of your net earnings (IRS: Self-employment tax).
The Social Security part only applies up to a yearly wage limit, so at high incomes the real amount is lower than shown. An extra 0.9% Medicare tax can apply at higher incomes.
Federal income tax, and state tax where you live, comes on top of the self-employment tax. The line "left for income tax" shows what your set-aside leaves for that.
Self-employed people usually pay tax during the year in quarterly estimated payments (IRS: Estimated taxes).
Questions people ask
How much should I set aside for taxes when self-employed?
Many self-employed people set aside about 25% to 30% of their profit. Your real number depends on your income, deductions and state, so check it with a tax professional.
What is the self-employment tax rate?
It is 15.3%: 12.4% for Social Security and 2.9% for Medicare, worked out on 92.35% of your net earnings from self-employment. The Social Security part stops at the yearly wage limit.
Do I pay self-employment tax on a small side income?
In general you owe it, and file Schedule SE, when your net earnings from self-employment are $400 or more for the year.
Is self-employment tax the only tax I pay?
No. Income tax comes on top of it, and many states have their own income tax as well.
Is this tax advice?
No. It is an estimate to help you save enough. A tax professional can tell you what you will really owe.
