How to Calculate and Pay Quarterly Taxes in 4 Steps
- Determine Net Schedule C Profit: Calculate your gross business revenue and subtract allowable ordinary and necessary business expenses (software, equipment, travel, health insurance, and home office deductions).
- Compute Self-Employment Tax (SECA 15.3%): Multiply your net profit by 92.35% to determine statutory taxable earnings. Apply 12.4% for Social Security (up to the annual wage base limit) plus 2.9% for Medicare.
- Apply the IRC §164(f) 50% Deduction: Subtract half of your total self-employment tax from your income. This above-the-line deduction lowers your Adjusted Gross Income (AGI) before computing federal income tax brackets.
- Divide Annual Total into 4 Equal 1040-ES Installments: Combine your net self-employment tax, federal income tax, and state taxes, subtract any W-2 withholdings or tax credits, and remit one-fourth by each quarterly deadline via IRS Direct Pay.
"If you do not pay enough tax through withholding and estimated tax payments, you may be charged a penalty. You also may be charged a penalty if your estimated tax payments are late, even if you are due a refund when you file your tax return." — Internal Revenue Service (IRS Publication 505: Tax Withholding and Estimated Tax)

As a general rule, if you expect to owe at least $1,000 in federal tax after subtracting withholdings and refundable credits, you must make estimated quarterly tax payments using IRS Form 1040-ES. This applies to independent contractors, freelancers, sole proprietors, LLC members, and creators.
Estimated payments are divided into four periods:
• Q1 (Jan 1 – Mar 31): Due April 15
• Q2 (Apr 1 – May 31): Due June 15
• Q3 (Jun 1 – Aug 31): Due September 15
• Q4 (Sep 1 – Dec 31): Due January 15 of the following year
Note: If the 15th falls on a weekend or federal holiday, payment is due the following business day.
• Q1 (Jan 1 – Mar 31): Due April 15
• Q2 (Apr 1 – May 31): Due June 15
• Q3 (Jun 1 – Aug 31): Due September 15
• Q4 (Sep 1 – Dec 31): Due January 15 of the following year
Note: If the 15th falls on a weekend or federal holiday, payment is due the following business day.
The IRS allows you to avoid underpayment penalties if you meet either of these two Safe Harbor benchmarks:
1. Pay at least 90% of the tax shown on your current year return, or
2. Pay 100% of the tax shown on your prior year return (increases to 110% if your prior year Adjusted Gross Income exceeded $150,000 for married filing jointly or $75,000 for single).
1. Pay at least 90% of the tax shown on your current year return, or
2. Pay 100% of the tax shown on your prior year return (increases to 110% if your prior year Adjusted Gross Income exceeded $150,000 for married filing jointly or $75,000 for single).
Employers pay half of their employees' Social Security and Medicare taxes (7.65%). Because freelancers pay both parts (15.3%), the IRS allows you an above-the-line deduction equal to 50% of your total self-employment tax under IRC §164(f). This reduces your Adjusted Gross Income (AGI) before calculating standard deductions and income tax brackets.
An S-Corporation election under IRS Form 2553 typically becomes advantageous when your net freelance profit consistently reaches $60,000 to $80,000+ per year. By paying yourself an IRS-defensible "reasonable salary" via W-2 and taking the remainder as shareholder distributions, you eliminate the 15.3% self-employment tax on distributions.
