Frequently Asked Questions
Why do freelancers pay 15.3% self-employment tax?↓
W-2 employees have half of their FICA taxes (7.65%) paid by their employer and half deducted from their paycheck. Independent contractors (1099) are considered both employer and employee, so they pay the full 15.3% (12.4% Social Security and 2.9% Medicare).
When are US quarterly estimated tax payments due?↓
IRS Form 1040-ES estimated payments are typically due on April 15 (Q1), June 15 (Q2), September 15 (Q3), and January 15 of the following year (Q4).
What is the 50% self-employment tax deduction?↓
Under IRS tax code, you can deduct 50% of your self-employment tax from your gross income on Form 1040 Schedule 1. This "above-the-line" deduction lowers your adjusted gross income (AGI) and reduces your income tax burden.
What limitation should I keep in mind regarding this calculation?↓
This calculator provides general informational estimates based on standard rates. It does not account for the Social Security wage cap threshold ($168,600+), the 0.9% Additional Medicare Tax on high earners, state-specific self-employment surcharges, or Section 199A Qualified Business Income (QBI) deductions.
