Freelance Quarterly Tax Deadlines (2026)

Short answer: as a freelancer the IRS expects you to pay tax as you earn it, in four estimated payments. For the 2026 tax year the due dates are April 15, June 15, September 15, 2026 and January 15, 2027. Miss them — or underpay — and you owe a penalty even if you settle up in April. Here are the exact dates, what each one covers, and the safe-harbor rule that keeps you penalty-free.

The four 2026 deadlines

Notice the "quarters" are uneven — Q2 covers only two months and Q4 covers four. If a due date lands on a weekend or federal holiday it rolls to the next business day. Confirm the exact dates each year at IRS.gov, as holidays can shift a deadline by a day or two.

Who actually has to pay?

You generally owe quarterly estimates if you expect to owe $1,000 or more in tax for the year after withholding. For most full-time freelancers with no W-2 job, that's almost everyone. If you also have a W-2 job (or a spouse who does), extra withholding from that paycheck can cover your freelance tax and let you skip the quarterly hassle.

The safe-harbor rule (your penalty shield)

You don't have to predict your income perfectly. The IRS won't charge an underpayment penalty if you pay, through the year, at least the smaller of:

• 90% of this year's total tax, or
• 100% of last year's total tax (110% if your prior-year adjusted gross income was over $150,000).

The second one is the easy lever: take last year's total tax, divide by four, and pay that each quarter. Even if you earn far more this year, you're protected from penalties — you just settle the balance in April. This is the single most useful rule for freelancers with bumpy income.

What happens if you miss a deadline

The penalty isn't a flat fine — it's calculated like interest on the amount you underpaid, for the days it was late. Skip Q1 and pay double at Q2 and you still owe a small penalty for the quarter the money was late. It's usually modest, but it compounds across four periods and is entirely avoidable. Paying something close to on time always beats paying nothing.

How to actually pay (5 minutes)

• IRS Direct Pay — free, straight from your bank account, no account needed. Choose "Estimated Tax" and the 2026 tax year.
• EFTPS — the Electronic Federal Tax Payment System; free, lets you schedule all four payments in advance.
• Card — works but carries a processing fee.
• Don't forget your state. Most states with an income tax have their own quarterly estimates on a similar schedule.

Stop guessing what to send the IRS

The hardest part of quarterly taxes is knowing the number. The $9 Freelance Rate & Tax Calculator spreadsheet projects your annual self-employment and income tax from your real income and expenses, so each quarterly payment is just that figure ÷ 4.

Frequently asked questions

What are the quarterly tax deadlines for freelancers in 2026?

For the 2026 tax year the estimated tax payments are due April 15, 2026, June 15, 2026, September 15, 2026, and January 15, 2027. If a date falls on a weekend or federal holiday it moves to the next business day.

Do freelancers have to pay quarterly taxes?

You generally must pay quarterly estimated taxes if you expect to owe at least $1,000 in tax for the year after any withholding. Most full-time freelancers without a W-2 job meet this threshold. If you also have a job with withholding, you can sometimes cover your freelance tax through extra paycheck withholding instead.

What is the safe-harbor rule for estimated taxes?

You avoid an underpayment penalty if you pay through the year at least 90% of the current year's tax or 100% of last year's tax, whichever is smaller. That prior-year figure rises to 110% if your previous adjusted gross income was over $150,000. Paying last year's tax divided by four is the simplest way to stay protected.

What is the penalty for missing a quarterly tax payment?

The penalty is calculated like interest on the amount you underpaid for the period it was late, rather than a flat fine. It is usually modest per quarter but compounds across the four periods, so paying close to on time keeps it small or zero.

How do I pay quarterly estimated taxes?

The easiest free options are IRS Direct Pay, which pulls from your bank account with no account setup, and EFTPS, which lets you schedule all four payments in advance. Choose "Estimated Tax" and the correct tax year. Most states with an income tax require separate quarterly payments on a similar schedule.
