The IRS requires quarterly payments to avoid penalties. Pay on time using these deadlines:
If you work as a freelancer, independent contractor, gig worker, or small business owner receiving 1099-MISC or 1099-NEC forms, understanding your tax obligations is critical. Unlike W-2 employees who have taxes automatically withheld from paychecks, 1099 workers are responsible for calculating and paying their own taxes throughout the year.
Self-employment tax is the equivalent of FICA taxes (Social Security and Medicare) that W-2 employees pay. The key difference: 1099 contractors pay both the employer and employee portions, totaling 15.3%:
Importantly, self-employment tax applies to 92.35% of your net earnings, not your gross income. This accounts for the employer-equivalent portion that would normally be tax-deductible for a business.
On top of self-employment tax, you also owe federal income tax based on your tax bracket. For 2025, most self-employed individuals fall into the 12%, 22%, or 24% brackets. Our calculator uses a simplified 12% estimate, but your actual rate depends on your total taxable income, filing status, and deductions.
Our calculator includes state-specific income tax rates for all 50 states. Nine states have no income tax (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming), while others range from 2.9% (North Dakota) to 13.3% (California for high earners). Always select your state of residence for accurate estimates.
Tracking business expenses is one of the most powerful ways to reduce your 1099 tax liability. Common deductible expenses include:
The IRS requires quarterly estimated tax payments if you expect to owe $1,000 or more annually. Missing payments results in underpayment penalties (0.5% per month, or 6% annually). Our calculator divides your annual tax liability into four equal payments aligned with IRS deadlines.
