On track for estimated payment
As a US freelancer, self-employed professional, or independent contractor, you're responsible for paying both the employee and employer portions of Social Security and Medicare taxes—plus federal income tax.
Unlike traditional employees, taxes aren't automatically withheld from your income. The IRS requires you to make quarterly estimated tax payments to avoid penalties and a massive tax bill at year-end.
This calculator helps you estimate your quarterly US federal tax payments based on your income, business expenses, and filing status. It calculates both self-employment tax and federal income tax so you know exactly how much to set aside.
What you'll get: Quarterly payment amounts, annual tax estimate, effective tax rate, and how much to set aside from each payment.
How Freelance Taxes Work
As a self-employed individual, you're responsible for both sides of payroll taxes that traditional employees split with their employer. Here's how this calculator estimates your tax liability:
Net Income =
Gross Income - Business Expenses
Self-Employment Tax =
(Net Income × 92.35%) × 15.3%
Adjusted Gross Income =
Net Income - (½ SE Tax) - Additional Deductions
Taxable Income =
AGI - Standard Deduction
Federal Income Tax =
Calculated using progressive tax brackets
For example: $80,000 gross - $10,000 expenses = $70,000 net. SE tax: ~$9,891. Income tax (single): ~$8,400. Total: ~$18,291 annually, or ~$4,573 quarterly.
Understanding the Components
Self-Employment Tax (15.3%)
This covers Social Security (12.4%) and Medicare (2.9%). Traditional employees pay 7.65% while their employer pays the other 7.65%. As self-employed, you pay both halves.
The 92.35% rule: You calculate SE tax on 92.35% of net income (not 100%) because the employer portion of SE tax is deductible. This approximates what W-2 employees pay.
Federal Income Tax (Progressive Rates)
Your income is taxed in brackets. The first portion is taxed at 10%, the next at 12%, then 22%, and so on. Your effective rate is usually much lower than your top bracket.
2024 rates: Single filers pay 10% on income up to $11,600, then 12% on $11,601-$47,150, then 22% on $47,151-$100,525, etc. Only the income in each bracket is taxed at that rate.
Standard Deduction
Before calculating income tax, you subtract the standard deduction from your adjusted gross income. This reduces your taxable income.
2024 amounts: Single: $14,600 | Married Filing Jointly: $29,200 | Head of Household: $21,900. You can itemize instead if deductions exceed the standard amount.
Quarterly Estimated Payments
The IRS requires you to pay taxes throughout the year, not just at tax time. Quarterly payments are due April 15, June 15, September 15, and January 15.
Avoiding penalties: You must pay at least 90% of the current year's tax or 100% of last year's tax (110% if AGI over $150,000). Underpayment results in penalties and interest.
Business Expense Deductions
You can deduct ordinary and necessary business expenses from gross income. This includes office supplies, software, equipment, marketing, professional development, insurance, and more.
Common deductions: Home office (simplified or actual), health insurance premiums (for self-employed), retirement contributions (SEP-IRA, Solo 401k), half of SE tax, mileage, travel, meals (50%), and professional services.
Above-the-Line Deductions
Certain deductions reduce your adjusted gross income before the standard deduction. These include half of self-employment tax, health insurance premiums, and retirement contributions.
Powerful savings: A $6,000 SEP-IRA contribution reduces both your income tax AND your SE tax, potentially saving $2,000+ in taxes while building retirement savings.
Important: This calculator provides US federal tax estimates only and is based on 2024 IRS tax rates. Actual tax liability depends on many factors including other income, tax credits, itemized deductions, state taxes, and more. This tool does not apply to non-US taxpayers. Consult a US CPA or tax professional for personalized advice and to maximize deductions.
8 Costly US Freelance Tax Mistakes
These mistakes cost US freelancers thousands in unnecessary taxes and penalties. Most are easily preventable with proper planning.
Not Setting Money Aside Throughout the Year
The Problem:
Spending all income as it comes in without saving for taxes, then scrambling at tax time or facing penalties for underpayment.
IMPACT
Massive tax bill you can't pay, payment plans with interest, or worse—penalties and potential liens. Many freelancers owe $10,000-$30,000+ at tax time.
The Fix:
Set aside 25-35% of every payment in a separate savings account immediately. Treat tax money as untouchable. Use the percentage from this calculator as your guide.
Missing Quarterly Payment Deadlines
The Problem:
Waiting until April 15 to pay all taxes instead of making quarterly estimated payments throughout the year.
IMPACT
IRS penalties and interest for underpayment, even if you pay the full amount by April 15. Penalties can be hundreds or thousands of dollars.
The Fix:
Mark quarterly deadlines on your calendar (Apr 15, Jun 15, Sep 15, Jan 15) and pay on time. Set up reminders and automate if possible. Use IRS Form 1040-ES.
Forgetting About Self-Employment Tax
The Problem:
Only budgeting for income tax and not realizing self-employment tax (15.3%) is separate and additional.
IMPACT
Your tax bill is $10,000+ higher than expected. On $70,000 net income, SE tax alone is nearly $10,000 before income tax even starts.
The Fix:
Understand you pay BOTH self-employment tax and income tax. Combined, your total tax rate is often 25-40% depending on income level.
Not Tracking Deductible Expenses
The Problem:
Failing to track and categorize business expenses throughout the year, then scrambling at tax time or missing deductions entirely.
IMPACT
Paying tax on thousands more than necessary. Missing $10,000 in deductions means paying $3,000-$4,000 extra in taxes.
The Fix:
Use accounting software or apps to categorize expenses as they happen. Save all receipts. Common deductions: home office, software, equipment, mileage, meals, insurance, professional development.
Mixing Personal and Business Finances
The Problem:
Using the same bank account and credit card for personal and business expenses, making it impossible to separate deductible expenses.
IMPACT
Can't prove business expenses to IRS if audited. Miss legitimate deductions because you can't identify them. Nightmare at tax time sorting through mixed transactions.
The Fix:
Open separate business checking account and credit card. Pay yourself a "salary" transfer to personal account. Keep business and personal finances completely separate from day one.
Not Deducting Health Insurance Premiums
The Problem:
Many self-employed people don't realize health insurance premiums are 100% deductible as an above-the-line deduction.
IMPACT
Missing a massive deduction that reduces both income tax and self-employment tax. Could save $2,000-$5,000+ annually.
The Fix:
Deduct health, dental, and long-term care insurance premiums you pay for yourself, spouse, and dependents. This is an adjustment to income, not an itemized deduction.
Ignoring Retirement Contributions as Tax Strategy
The Problem:
Not contributing to SEP-IRA or Solo 401(k), missing the dual benefit of tax deductions and retirement savings.
IMPACT
Paying higher taxes now and not building retirement savings. A $10,000 contribution could save $3,000-$4,000 in taxes immediately.
The Fix:
Max out SEP-IRA (25% of net earnings, up to $66,000 in 2024) or Solo 401(k) ($23,000 + 25% of compensation). Contributions reduce current year taxes significantly.
Filing as a Sole Proprietor When LLC or S-Corp Makes Sense
The Problem:
Defaulting to Schedule C (sole proprietor) without exploring entity structures that could save thousands in SE tax.
IMPACT
Paying full 15.3% SE tax on all income when S-Corp election could save $3,000-$10,000+ annually depending on income level.
The Fix:
Once earning $60,000-$80,000+, consult a CPA about S-Corp election. You can pay yourself a reasonable salary and take remaining profit as distributions (avoiding SE tax on distributions).
The Bottom Line
Tax planning isn't optional for freelancers—it's essential for profitability. Work with a CPA who specializes in self-employment, track everything meticulously, and treat quarterly payments as non-negotiable. The time and money invested in proper tax management pays for itself many times over in savings and peace of mind.
