How to calculate and pay your quarterly estimated taxes
The IRS requires freelancers to pay estimated taxes four times per year because you don't have an employer automatically withholding taxes from your paycheck. You'll pay 25% of your annual estimated tax liability each quarter to avoid penalties.
First, you need to calculate how much you owe. The general rule is you must pay either 90% of this year's tax liability or 100% of last year's (110% if your prior year AGI exceeded $150,000). For most new freelancers, using 100% of last year's taxes is simpler and safer.
Example: $60,000 freelance income calculation
Let's say you expect to earn $60,000 in freelance income in 2026:

Best for people with W-2 jobs who also have 1099 freelance income and need to coordinate withholding
Coordinating W-2 withholding with freelance income
As a side hustler with both W-2 and 1099 income, you have more flexibility in how you cover your tax obligation. You can either make quarterly estimated payments or increase your W-2 withholding to cover the additional taxes from freelance income.
Example: $70,000 W-2 + $20,000 freelance income
Let's say your W-2 job withholds taxes for $70,000 salary, and you earn an additional $20,000 freelancing:
Option 1: Quarterly payments
Option 2: Increase W-2 withholding
Payment timing strategy
Since W-2 withholding is considered paid evenly throughout the year, increasing your withholding can help you avoid underpayment penalties even if you start late in the year. Quarterly estimated payments, however, must be made by specific deadlines for each quarter.
For side hustlers earning under $30,000 in freelance income, increasing W-2 withholding is often simpler and provides better penalty protection.
Key takeaway: Side hustlers can either make quarterly payments on freelance income or increase W-2 withholding to cover the additional tax liability from 1099 income.

Advanced payment strategies for full-time freelancers
As a full-time freelancer, quarterly estimated taxes are a major cash flow consideration. Your income likely varies throughout the year, making it important to understand the annualized income installment method and safe harbor rules.
Safe harbor vs. current year liability
You have two options to avoid underpayment penalties:
1. Safe harbor: Pay 100% of last year's tax liability (110% if AGI > $150,000)
2. Current year: Pay 90% of this year's actual tax liability
For freelancers with growing income, the safe harbor method provides certainty. If your income dropped this year, the current year method saves money.
Annualized income method for uneven income
If your freelance income is seasonal or project-based, you can use the annualized income installment method (Form 2210 Schedule AI) to adjust payments based on actual quarterly income rather than paying equal amounts.
Example: Wedding photographer earning 70% of income in Q2-Q3:
Cash flow management tips
1. Set aside 25-30% of each payment immediately for taxes
2. Use EFTPS scheduled payments to automate quarterly payments
3. Consider monthly transfers to a tax savings account ($1,100/month for $13,000 annual liability)
4. Track payments carefully using accounting software or our freelance dashboard
Full-time freelancers should also consider making state estimated tax payments, which often have different due dates and calculation methods than federal payments.
Key takeaway: Full-time freelancers should use the safe harbor method for predictable payments and consider the annualized income method if income varies significantly by season.
