How do I calculate my Q1 2026 estimated tax payment as a freelancer?

Your Q1 2026 estimated tax payment is due April 15, 2026, the same day as your 2025 tax return. Here's how to figure out what you owe:

Who must pay estimated taxes?

You're required to make estimated payments if you expect to owe $1,000 or more in federal tax for 2026 after subtracting withholding and credits. This applies to most freelancers, independent contractors, sole proprietors, and gig workers.

Two safe harbor methods (choose one):

• 100% of prior year method: Divide your total 2025 tax liability by 4 and pay that amount each quarter. If your 2025 AGI was above $150,000 ($75,000 if married filing separately), you need to pay 110% of prior year tax divided by 4. This method guarantees no underpayment penalty regardless of how much you earn in 2026.

• 90% of current year method: Estimate your 2026 income and calculate 90% of the expected tax, divided by 4. This is more accurate but requires you to project your income.

What taxes to include in your calculation:

• Federal income tax at your marginal rate
• Self-employment tax: 15.3% on net self-employment income (12.4% Social Security on the first $168,600 in 2026, plus 2.9% Medicare on all earnings). You get to deduct half of SE tax as an above-the-line deduction.
• Don't forget state estimated taxes if your state requires them

Quick estimate for a freelancer earning $100,000 net:

• Self-employment tax: ~$14,130
• Federal income tax (single, standard deduction): ~$12,000-$14,000
• Total annual: ~$26,000-$28,000
• Quarterly payment: ~$6,500-$7,000

How to pay:

• IRS Direct Pay (irs.gov/directpay) for free bank transfers
• EFTPS (Electronic Federal Tax Payment System) for scheduled payments
• IRS2Go app
• Mail a check with Form 1040-ES payment voucher

2026 quarterly due dates:

• Q1: April 15, 2026
• Q2: June 15, 2026
• Q3: September 15, 2026
• Q4: January 15, 2027

Pro tip: If your income is uneven, you can use the annualized income installment method (Form 2210, Schedule AI) to potentially lower your earlier payments if you earn more later in the year.
