When you work as an employee, your employer handles a significant portion of your tax obligations — withholding income tax, paying half of your Social Security and Medicare taxes, and sending everything to the IRS on your behalf. When you become an independent contractor, all of that becomes your responsibility.
The self-employment tax rate is 15.3% on net earnings — that covers both the employee and employer portions of Social Security and Medicare. On top of that, you owe federal income tax on your profits. Many new contractors are caught off guard by the size of their first tax bill because they didn't set money aside throughout the year.
The IRS generally requires self-employed individuals to make estimated tax payments four times a year — in April, June, September, and January. These payments cover both income tax and self-employment tax. Missing them can result in underpayment penalties, even if you pay everything you owe by the April filing deadline.
The good news is that contractors can deduct legitimate business expenses from their taxable income. Home office space, equipment, software subscriptions, professional development, business travel, and a portion of your health insurance premiums may all be deductible. The key is keeping organized records — receipts, invoices, and bank statements — throughout the year, not just at tax time.
Separating your business and personal finances is one of the most important habits you can build. A dedicated business checking account and credit card make it far easier to track income and expenses, prepare for taxes, and demonstrate the legitimacy of your deductions if you're ever audited.
Tax rules for contractors can be complex, and they vary depending on your industry, state, and business structure. Working with a financial professional who understands self-employment can help you stay compliant, avoid surprises, and keep more of what you earn.
