Quarterly Taxes for Freelancers: 2026 Guide and Dates
US freelancers pay estimated taxes on four dates — April 15, June 15, September 15, and January 15 — and must pay once they expect to owe $1,000 or more for the year after withholding and refundable credits. Employees have taxes withheld every paycheck; freelancers get four deadlines instead, and missing one costs penalties plus interest even if everything is paid by April. Here is the system, with a worked safe-harbor example and the payment routes that give you a receipt.
Who has to pay quarterly?
In the US, you generally must make quarterly estimated payments if you expect to owe $1,000 or more for the year after withholding and refundable credits. That threshold comes straight from the IRS estimated taxes guidance. If you freelance seriously at all, you'll clear it.
The four deadlines
- April 15 — Q1 (Jan–Mar income)
- June 15 — Q2 (Apr–May)
- September 15 — Q3 (Jun–Aug)
- January 15 — Q4 (Sep–Dec) of the following year
Note the uneven quarters: Q2 covers only two months. Freelancers with lumpy income should estimate per-quarter income rather than dividing the annual bill by four — the IRS Form 1040-ES annualized income worksheet exists for exactly this.
| Payment | Due date | Income period it covers | Level installment (example) |
|---|---|---|---|
| Q1 | April 15 | January – March | $6,000 |
| Q2 | June 15 | April – May | $6,000 |
| Q3 | September 15 | June – August | $6,000 |
| Q4 | January 15 of the following year | September – December | $6,000 |
The last column is the installment from the worked example below: four equal payments totaling $24,000. Equal quarters are the default, not a requirement — the annualized income worksheet lets you size each payment to the quarter it covers.
How much? The safe harbor rules
You avoid underpayment penalties if you pay, across the year, the smaller of:
- 90% of the current year's tax, or
- 100% of last year's tax (110% if your adjusted gross income was over $150,000 — a detail high earners miss and that every major tax-software provider's guide repeats, because it's the single most common safe-harbor mistake).
If last year's income was stable, paying 100% of last year's bill in four chunks is the stress-free path — even if this year turns out better.
Worked example: choosing your safe harbor
Suppose last year's return showed a total tax of $24,000 with adjusted gross income of $140,000, and you expect this year's tax to land around $28,000.
- 90% of the current year: $28,000 × 90% = $25,200 for the year, which is $6,300 per quarter.
- 100% of the prior year: $24,000 × 100% = $24,000 for the year, which is $6,000 per quarter.
- The 110% test: last year's AGI was under $150,000, so 100% is enough. Had it been $180,000, the required payment would rise to $24,000 × 110% = $26,400, or $6,600 per quarter.
- Pay the smaller: $6,000 per quarter satisfies the prior-year safe harbor, so no underpayment penalty accrues.
Formula: Quarterly installment = (prior-year tax × safe-harbor percentage) ÷ 4.
One thing the safe harbor does not do is pay your tax. At $6,000 a quarter you will have handed over $24,000 against an expected $28,000 liability, so roughly $4,000 is still due with the return. The safe harbor protects you from the penalty, not from the bill — which is exactly why the set-aside account has to run on a percentage, not on a schedule.
Practitioner note: In practice, steady earners should default to the prior-year safe harbor and stop optimizing: four $6,000 vouchers you actually send beat a theoretically perfect annualized schedule you abandon in July. Save the worksheet for genuinely lumpy years — it earns its keep when one quarter carries most of the income, not when every quarter looks alike.
When income moves mid-year
A new retainer landing in August does not make your spring payments late if you are riding the prior-year safe harbor: that route forgives nothing about the total tax, but it forgives the shape of it, because the penalty only compares what you paid each period against what was required for that period. What the new retainer does change is the April balance — every dollar of added profit carries income tax and, above $400 of net earnings, self-employment tax on 92.35% of it as well. Recompute your percentage when a contract changes size rather than when the calendar changes, and move the difference into the tax account the same week the invoice clears. The tax set-aside calculator turns net profit into the number to transfer.
The penalty is worse than it looks
The underpayment penalty is an interest charge computed per quarter, from each quarter's deadline — so being 9 months late on the April payment costs 9 months of interest on that slice. The rate floats quarterly (it's tied to the federal short-term rate plus a margin; the IRS publishes the current rate each quarter). Interest compounds the mistake; paying on time is cheaper than any savings account pays you.
The practical system
- Set aside a percentage of every payment — 25–30% of net for most US freelancers (our set-aside percentage guide explains the derivation, and the tax set-aside calculator computes it per invoice).
- Keep it in a separate account you never touch.
- Calendar all four deadlines with reminders a week ahead.
- Pay via IRS Direct Pay — free, instant, and gives you a confirmation number. Never ignore a quarter because income was small; the $1,000 annual threshold is the only grace you get.
Withholding counts as payments too
If you hold a W-2 job alongside freelancing — or your spouse does — the tax withheld from those paychecks counts toward the same annual requirement, and the IRS generally treats withholding as paid evenly across the year. That quirk is useful: a December bonus that withholds heavily can shore up a spring you underpaid, because the withholding is credited against every quarter rather than the quarter it happened. The mechanics are set out in IRS Publication 505. Blending salary and freelance income is its own calculation, so we built a mixed W-2/1099 calculator for it.
Your first year: the no-tax-liability exception
The rules contain one clean exemption for beginners. If you were a US citizen or resident for all of the prior year and had no tax liability for that full year — your total tax was zero, or you were not required to file a return — you do not have to make estimated payments for the current year. That is the exception as Form 1040-ES states it. The relief lasts exactly one taxable year: the first time you owe, the four deadlines apply to you like everyone else's.
How to actually pay
IRS Direct Pay pulls the money straight from your bank account, costs nothing, and returns a confirmation number you should store with that quarter's records. The IRS payments page also lists card and bank-transfer options, and a check with a Form 1040-ES voucher remains valid. Two habits prevent most problems: tag every payment with the tax year it applies to (payments default to the current year, which is wrong in January), and never skip a quarter because that quarter's invoices were small — the $1,000 test is annual, and penalties accrue per missed due date.
When the safe-harbor math goes wrong:
- Your first profitable year. Last year's tax was $0, so 100% of zero is zero — the safe harbor asks nothing quarterly, but the full bill still lands in April; pay on current-year estimates instead.
- A spouse's income jumps. The 110% test keys off household AGI over $150,000 — a raise you never saw can flip your required percentage from 100% to 110%.
- You skip Q1 because income was small. The $1,000 test is annual, and interest starts from each missed deadline — a quiet spring does not pause the clock.
- You satisfied the IRS and forgot the state. State estimates run on separate vouchers and calendars — the federal safe harbor says nothing about Sacramento or Albany.
Paying online: Direct Pay vs EFTPS
Both routes pay the IRS directly with no fee for a bank transfer. Direct Pay pulls a single payment straight from your bank account each time you use it — pick the tax year, the estimated-tax reason, and the quarter, submit, and store the confirmation number with that quarter's records. EFTPS is an enrolled account: you enroll once, then you can schedule payments in advance, review payment history, and see every quarter in one place. Use Direct Pay when you want a free one-off bank pull per payment; use EFTPS when you want scheduling plus a history of what you already sent. Either way, tag every payment with the correct tax year — payments default to the current year, which is wrong in January — and keep the confirmation number with the quarter it covers.
First-payment worked example: a new freelancer's $72,000 year
A freelancer in their first profitable year nets $72,000 after expenses, with no prior-year tax to base a safe harbor on, so the first-year payments run on current-year estimates. Using the site formula at a 22% income-tax rate:
- Self-employment tax: $72,000 × 92.35% = $66,492 of taxable net earnings, then $66,492 × 15.3% = $10,173.28.
- Federal income tax: $72,000 × 22% = $15,840.
- Annual total: $10,173.28 + $15,840 = $26,013.28.
- Per quarter: $26,013.28 ÷ 4 = $6,503.32, so four payments of about $6,503.
Formula: Quarterly installment = ((net profit × 92.35% × 15.3%) + (net profit × income-tax rate)) ÷ 4. Because last year's tax was $0, the prior-year safe harbor requires almost nothing quarterly — but the full April bill still arrives, so pay on these current-year estimates instead and move each quarter from the set-aside account the same week it is due.
A note on state estimates
States run separate estimated-tax systems with their own vouchers, accounts, and calendars — the federal safe harbor, federal deadlines, and federal payment routes above say nothing about what your state expects. Pay state estimates through your state's own system, on its own dates, and keep federal and state confirmations in separate records so a clean federal file never hides a missed state quarter.
Outside the US
Most countries run parallel systems: the UK's "payments on account" (two payments a year toward next year's tax, via gov.uk), France's quarterly aperçus, and similar install-ahead schemes across the EU. The principle is the same everywhere: the tax office expects its money before you've earned it, so the set-aside account is non-negotiable.
