As a self-employed individual, you are responsible for managing your own income, expenses, and tax obligations. Unlike traditional employees who have taxes withheld from each paycheck, self-employed individuals must proactively calculate and pay their taxes. This calculator helps you estimate your net income after accounting for business expenses and estimated taxes.
Key Concepts:
Gross Revenue: This is the total amount of money you've earned from your business activities before deducting any expenses. It's the top-line figure.
Business Expenses: These are the costs incurred in the ordinary course of running your business. Examples include office supplies, rent for a home office (if applicable), software subscriptions, marketing costs, professional development, and travel expenses related to your work. Deducting legitimate business expenses reduces your taxable income.
Net Income (Before Taxes): This is calculated by subtracting your total business expenses from your gross revenue. It represents your profit from the business.
Net Income (Before Taxes) = Gross Revenue - Business Expenses
Estimated Tax Rate: Self-employed individuals typically need to pay self-employment taxes (Social Security and Medicare) in addition to income taxes. The estimated tax rate you input should reflect your overall projected tax liability, considering federal, state, and local income taxes, as well as self-employment taxes. This is an estimate, and your actual tax rate may vary. It's advisable to consult with a tax professional to determine an accurate rate for your situation.
Estimated Net Income (After Taxes): This is the final figure after deducting estimated taxes from your net income (before taxes).
Estimated Net Income (After Taxes) = Net Income (Before Taxes) * (1 - (Estimated Tax Rate / 100))
How the Calculator Works:
Enter Gross Revenue: Input the total income you've received from all your self-employed activities.
Enter Business Expenses: Sum up all eligible costs associated with running your business.
Enter Estimated Tax Rate: Provide an estimated percentage that represents your total anticipated tax burden (income tax + self-employment tax).
Calculate: The calculator first determines your net income before taxes by subtracting expenses from revenue. Then, it applies your estimated tax rate to this figure to estimate the amount of tax you'll owe. Finally, it subtracts the estimated taxes from your net income (before taxes) to give you your estimated net income after taxes.
