2026 quarterly tax due dates
The IRS divides the tax year into four uneven payment periods. Each has a firm due date — if the date falls on a weekend or holiday, the deadline moves to the next business day.
Note that Q2 covers only two months (April–May) while Q3 covers three (June–August). This trips up a lot of first-time freelancers — the June payment sneaks up fast after the April one.
Who needs to pay quarterly taxes?
You're required to make estimated tax payments if you expect to owe $1,000 or more in federal tax for the year after subtracting withholding and refundable credits. This threshold hasn't changed in over a decade — it applies to 2026 just as it did in prior years.
In practice, this means almost every freelancer, independent contractor, sole proprietor, and gig worker earning more than a few thousand dollars per year. If you receive a 1099-NEC or 1099-K, you almost certainly need to pay quarterly.
The rule also applies if you have significant non-wage income from investments, rental properties, or side businesses — even if you also have a W-2 job. The test is whether your total withholding covers what you'll owe.
How to calculate your quarterly tax payment
There are two IRS-approved methods for calculating quarterly payments. You only need to satisfy one of them to avoid the underpayment penalty.
Method 1: Current-year estimate (90% rule)
Estimate your total tax liability for 2026 and pay at least 90% of that amount across your four quarterly payments. This method works best if your income is predictable and relatively stable. The challenge: you're guessing at income you haven't earned yet.
Method 2: Prior-year safe harbor (100%/110% rule)
Pay 100% of your prior year's total tax liability, divided into four equal payments. If your 2025 adjusted gross income exceeded $150,000 ($75,000 if married filing separately), the threshold is 110% instead of 100%.
This is the safest method for most freelancers because it's based on a known number — your 2025 return. Even if your income doubles in 2026, you won't face an underpayment penalty as long as you've paid in at least 100% (or 110%) of last year's total tax.
If your income is shrinking: use the current-year estimate. Overpaying based on a higher prior year ties up cash you need.
If your income is steady: either works. The safe harbor is simpler since you already have the number from last year's return.
Step-by-step: calculate your first payment
Estimate your net self-employment income
Total expected revenue minus business expenses. If you're using the prior-year method, pull this from your 2025 Schedule C, line 31. For a current-year estimate, use your best projection.
Calculate self-employment tax
Multiply net income × 92.35% × 15.3%. The 92.35% factor is the IRS adjustment — you only pay SE tax on 92.35% of net earnings. On $60,000 net income: $60,000 × 0.9235 × 0.153 = $8,478.
Calculate income tax
Start with net SE income. Subtract the deductible half of SE tax ($4,239 in our example). Subtract the standard deduction ($15,000 for single filers in 2025 — the 2026 figure is typically announced in late 2025 and is usually slightly higher). Apply all eligible deductions. Then apply the federal tax brackets to the remaining taxable income.
Add SE tax + income tax, then divide by 4
Your total estimated federal tax divided by four equals each quarterly payment. On $60,000 net SE income with no other income or credits, the math works out to roughly $10,700 total — about $2,675 per quarter.
How to actually pay
The IRS offers four payment methods. All are free except credit/debit cards.
| Method | How | Fee | Speed |
|---|---|---|---|
| IRS Direct Pay | irs.gov/directpay — bank account | Free | 1–2 business days |
| EFTPS | eftps.gov — scheduled bank transfer | Free | Schedule in advance |
| IRS2Go app | Mobile app — bank or card | Free (bank) / 1.85–1.98% (card) | Same day |
| Mail a check | Form 1040-ES voucher + check | Free (plus postage) | Mail processing time |
IRS Direct Pay is the simplest option for most people. Go to irs.gov/directpay, select "Estimated Tax" as the reason for payment, choose the correct tax year (2026) and quarter, enter your bank info, and confirm. You get an instant confirmation number. No account creation required.
EFTPS (Electronic Federal Tax Payment System) requires enrollment — it takes about a week to receive your PIN by mail. The advantage: you can schedule payments in advance and set up recurring payments. If you know you'll owe the same amount each quarter, schedule all four payments in January and never think about it again.
Don't forget state estimated taxes
Most states with an income tax also require quarterly estimated payments. The due dates usually — but not always — match the federal schedule. Notable exceptions include some states that use different quarters or have a single annual deadline for estimated taxes.
States with no income tax (and therefore no estimated payments needed): Alaska, Florida, Nevada, New Hampshire (no earned income tax), South Dakota, Tennessee (no earned income tax), Texas, Washington, and Wyoming.
For everyone else: check your state's department of revenue website for the specific due dates and payment portal. Most states have their own online payment system. For help figuring out exactly how much to set aside including state taxes, see our tax set-aside guide.
What happens if you miss a payment
The IRS charges an underpayment penalty calculated as interest on the unpaid amount. The penalty rate is the federal short-term rate plus 3 percentage points, updated quarterly. As of early 2026, the penalty rate is approximately 7–8% annualized — applied only to the underpaid portion for the days it was late.
The penalty is not catastrophic. Missing one quarter by a month on a $2,500 payment costs roughly $15–17 in penalties. It's an annoyance, not a crisis. That said, the penalties compound if you miss multiple quarters, and you'll still owe the full tax amount plus penalties at filing time.
2. Pay at least 90% of this year's actual tax via current-year estimates.
3. Owe less than $1,000 when you file. If your withholding + estimated payments leave you owing under $1,000, no penalty applies regardless of when you paid.
Real example: freelance designer earning $72,000
Alex is a freelance graphic designer. In 2025, her net Schedule C income (after business deductions) was $72,000. She's single, files as a sole proprietor, and takes the standard deduction.
Self-employment tax: $72,000 × 92.35% × 15.3% = $10,172
Deductible half of SE tax: $5,086
Adjusted gross income: $72,000 − $5,086 = $66,914
Taxable income after standard deduction: $66,914 − $15,000 = $51,914
Federal income tax (2025 brackets): 10% on first $11,925 ($1,193) + 12% on $11,926–$48,475 ($4,386) + 22% on $48,476–$51,914 ($757) = $6,336
Total federal tax: $10,172 (SE) + $6,336 (income) = $16,508
Quarterly payment (safe harbor): $16,508 ÷ 4 = $4,127 per quarter
Alex schedules four $4,127 payments via EFTPS in January. If she earns more in 2026, she'll owe a balance at tax time but faces zero penalties. If she earns less, she'll get a refund.
Form 1040-ES: do you need it?
Form 1040-ES is the IRS worksheet for calculating estimated tax. You don't need to file it — it's a worksheet for your own use. If you pay online (Direct Pay or EFTPS), you never touch this form. The only time you use the printed 1040-ES is if you're mailing a check — the form includes payment vouchers with your info pre-filled.
Most tax software (TurboTax, FreeTaxUSA, TaxAct) will calculate your estimated payments and generate the vouchers when you file your prior-year return.
Tips from actual freelancers
Open a separate tax savings account. Every time you get paid, immediately transfer 25–30% to a savings account earmarked for taxes. When the quarterly deadline arrives, the money is sitting there. This is the single most effective habit for avoiding quarterly tax stress. For exact percentages by income level and state, see our how much to set aside guide.
Use the prior-year safe harbor. It removes all guesswork. You already know the number. Divide by four. Done.
Track deductions year-round. Your quarterly payment amount depends directly on your net income — and net income depends on deductions. The more deductions you track, the lower your actual liability. Don't leave money on the table because you forgot to log a business expense in March.
Know your Schedule C. Your quarterly estimate is essentially a preview of what your Schedule C will look like at year's end. Understanding the form makes estimating easier.
