Start with your projected annual freelance income
For your first quarter as a freelancer, you need to estimate your entire year's income and taxes, then divide by four. According to IRS Publication 505, you must pay either 90% of your current year's tax liability or 100% of last year's taxes (110% if last year's AGI exceeded $150,000) to avoid penalties.
Since this is your first year freelancing, you likely don't have prior self-employment tax history, so focus on the 90% rule.
Step-by-step calculation for your first quarter
Step 1: Project your annual freelance income
Estimate conservatively. If you think you'll make $1,500-2,500 per month, use $2,000 ($24,000 annually).
Step 2: Calculate your self-employment tax
Step 3: Calculate your income tax
Step 4: Total annual tax liability
Step 5: First quarter payment
Real example: $20,000 projected freelance income
Adjustments you should make
If you have other income: Include your W-2 income and withholding in the calculation. You only pay estimated taxes on the amount NOT covered by withholding.
If you're married: Your tax bracket depends on your spouse's income too. Use married filing jointly brackets and standard deduction ($30,000 for 2026).
If you have business expenses: Reduce your net income by legitimate business deductions (home office, equipment, software, etc.).
What you should do right now
1. Make a conservative estimate of your annual freelance income
2. Use our quarterly estimator tool to run the exact calculations with your specific situation
3. Set up automatic transfers of 25-30% from each payment you receive
4. Pay your first quarter by April 15, 2026 (or January 15 if you started freelancing in January)
Important timing note: If you didn't earn freelance income in January, your first payment isn't due until April 15. But if you earned income in January-March, you must pay by April 15 for the entire first quarter.

Best for people adding freelance income to their existing W-2 job
Factor in your existing W-2 withholding
As a side hustler, your calculation is more complex because you already have tax withholding from your W-2 job. You only need to pay estimated taxes on the gap between your total tax liability and what's already being withheld.
Example: $50,000 W-2 + $10,000 side hustle
Your W-2 situation:
Adding freelance income:
Your quarterly payment:
The safe harbor rule for side hustlers
Since you had tax liability last year from your W-2, you can use the "safe harbor" rule: pay 100% of last year's total tax liability (110% if AGI over $150,000) to avoid penalties, regardless of what you owe this year.
If your total tax last year was $8,000 and your W-2 withholding this year will be $6,000, you only need $2,000 in estimated payments ($500 per quarter) to meet safe harbor.
Quick decision framework
Choose the LOWER of:
1. 90% of current year liability
2. 100% of last year liability (safe harbor)
This gives you penalty protection while you figure out your actual earnings pattern.
Key takeaway: Side hustlers should calculate estimated taxes on only the additional tax liability beyond their W-2 withholding, typically 30-35% of net freelance income.
Key Takeaway: Side hustlers pay estimated taxes only on the gap between total tax liability and existing W-2 withholding, usually 30-35% of freelance income.

Best for freelancers whose income varies significantly by season or quarter
Use the annualized income installment method
If your freelance income is seasonal (like tax preparation, holiday retail, or summer tourism), the standard quarterly method can create cash flow problems. The IRS allows the "annualized income installment method" that bases each payment on your actual income to date.
How annualized payments work
Instead of: 25% of annual estimate each quarter
You pay: Based on actual income earned through each quarter
Example - Holiday photographer:
Standard method: $1,875 each quarter (assuming $30k annual)
Annualized method: $150, $375, $75, $1,800 respectively
When to use this method
Important: You must file Form 2210 (Underpayment of Estimated Tax) to justify the unequal payments, even if you owe no penalty.
Key takeaway: Seasonal freelancers can use the annualized income method to match quarterly payments to actual earnings, but must file Form 2210 to document the calculation.
Key Takeaway: Seasonal freelancers can match quarterly payments to actual earnings using the annualized income method, but must file Form 2210 to justify unequal payments.
